SHORT COURSE ON OREMICROSCOPY AND ADVANCED

MINERAL TECHNIQUES FOR IRONAND RELATED MINERALS TOPERWAJA STEEL SDN. BHD.

KEMAMAN, TERENGGANU

3 - 4 April 2012, the above short coursewas organized at the Universiti Sains MalaysiaEngineering Campus when the management ofPerwaja Steel Mill Plant in the Telok KalongIndustrial Estate, Kemaman, Terengganuappointed the School of Materials and MineralResources Engineering in USM as the officialtrainer for ore microscopy and advanced min-eral techniques, in preparation for their futureiron ore exploration/evaluation, mining andprocessing undertaking in Terengganu.

Perwaja is an integrated steelmaker thatproduces direct reduced iron (DRI), and semi-finished long steel products such as billets,beam blanks and blooms. It commands 17%market share of semi-finished long steel prod-ucts and manufactures 40% of the country’sDRI production, which can produce 1.8 milliontonnes of DRI annually, contributing 12% ofthe total sales. Its steel making plant, locatedin Kemaman, Terengganu, has a capacity ofproducing 1.5 million tonnes of steel annually.Its rolling mills in Gurun, Kedah produce sec-tions, H-beams and I-beams, bars, wire rods,channels, angles and nails. Perwaja supplies its

products to the domestic market as well asexports to countries such as Indonesia, HongKong, Korea and Singapore.

The aim of the project is to fulfill the rawmaterial (iron ore) requirement of the steelmills which is currently imported at exorbitantprices from countries located half way aroundthe world such as Chile and Brazil.Development of their own iron ore resourcewould ensure a stable and reliable local supplyof raw material for their plant. Several keystaffs and engineers in the R&D, processingand supply chain departments attended thetraining course, which included both theoryand practical in the laboratory using the polar-izing ore microscope and several sets of pol-ished sections and hand specimens. A tour wasalso conducted of the school facilities toexplain all the other advanced techniques suchas the SEM with EDAX, XRD and XRF which canbe used to complement the training. Theadvantage of holding the training in the Schoolwas that several enthusiastic staffs and gradu-ate students were also able to join in the train-ing without taking up too much resources ofthe trainers and facilities.

The course content was aimed at develop-ing a better understanding of iron and associ-ated metallic minerals as well as the variouscomponents of the ore microscope in terms oftheir functions and applications. Another areathat was touched upon was the systematicstudy of the optical properties of the variousmineral groups in a practical manner. Thesestudies should aid participants in the identifica-tion and confirmation of several minerals notrecognizable from hand specimen studiesalone. The optical properties of minerals inreflected light are very different from the min-erals under normal hand specimen studies, andhence complement each other.

The training is considered to have beenvery successful and to have fulfilled one of thekey mission of the university which is in trans-forming knowledge from the academics to theindustry to ensure a better tomorrow for thepeople and the country. We wish to thank theDean, and all the academic, technical andlogistical staffs for their invaluable supportthroughout the training.

Selain untukmemenuhi keperluan kursus universiti iaitusubjek Hubungan Etnik, para peserta telahmengambil inisiatif untuk mengumpul bebera-pa jenis barang keperluan untuk dijadikansumbangan kepada masyarakat orang asli diTasik Banding.

Kemajuan dari segi sistem perhubungandapat diperhatikan didalam kalangan pen-duduk orang asli dimana terdapat dikalanganmereka yang sudah mempunyai telefon bimbitbagi tujuan komunikasi serta sebagai mediumuntuk hiburan (mendengar lagu, mengambilgambar, video dan sebagainya). Capaiantelekomunikasi yang rendah, menghadkanpenggunaan untuk berhubung kecuali jikaberada di bandar. Kekurangan utama bagimasyarakat orang asli di Tasik Banding adalahkeperluan perkhidmatan pusat rawatan kesi-hatan. Semasa lawatan, terdapat seorang anakkecil yang mengalami masalah demam panasdan malangnya tidak dapat dibawa ke pusatrawatan berdekatan. Perasaan sedihmenyelubungi peserta lawatan apabila melihatkeadaan anak kecil itu. Jarak dan masalahkewangan menjadi halangan untuk ibu bapaanak kecil itu membawanya ke tempatrawatan.

Lawatan dan sumbangan yang dihulurkankepada masyarakat orang asli Tasik Bandingmampu meringankan beban dan membantumenyelesaikan beberapa masalah yang dipikuloleh mereka. Sebagai masyarakat yang pri-hatin, tanggungjawab membantu merekadapat memberikan kesan yang sangat positifkepada masyarakat yang menerima kunjun-gan. Semoga program yang bermanfaat inidapat diteruskan pada masa akan datang.Syabas dan tahniah kepada semua yang telahmenjayakan program ini dari semua wargaPPKBSM.

Rheological and mechanical propertiesof allylic monomers as reactive plasticiz-

ers of polyphenylene oxide

Arjulizan Rusli* Wayne D. Cook**

*School of Materials and Mineral ResourcesEngineering, Universiti Sains Malaysia

**Department of Materials Engineering,Monash University, Clayton, Victoria, Australia

1.0 Introduction

Thermoplastics such as polyphenylene oxide(PPO), polyetherimide and polyethersulfonepossess desirable properties such as highstrength and toughness and very good dimen-sional stability. However, their applications arealways limited due to their high melt viscositywhere they require to be processed at hightemperature and long processing time whichmay result in degradation and loss of theirdesirable properties. A number of researchers [1-3] have reportedon the addition of a small amount of crosslink-able monomers as plasticizers to improve pro-cessibility of thermoplastics by which, unlikecommon plasticizers, can be polymerized into acrosslinked phase at the end of processing ofthe blend. These blend components are initial-ly miscible but then phase separate into ther-moplastic and thermoset rich phases duringcure due to reduction of the entropy of mixingwith the progress of polymerization process. Ifthe thermoplastic forms the continuous phase,the properties of the thermoplastic can beretained. In addition, if the monomers formcrosslinked particles they can act as reinforcersor tougheners depending whether they arerigid or rubbery.Most of the research on the application of athermosetting monomer as reactive solvent forPPO used epoxy monomers but there has beenmuch less research on radically initiated plasti-cized monomers. Allylic monomers undergogelation at relatively high conversion havebeen found to be useful as reactive plasticizersto improve processing of thermoplastics suchas polycarbonate [4], PVC [5] and PPO [6-8].Our previous study on solubility, the phase dia-gram and viscosity of various allylic monomersin PPO also shows that ortho-diallyl phthalate(DAOP) monomer is a suitable reactive plasti-cizer in improving processibility of PPO [7]while curing studies on DAOP with various ini-tiators and the blends PPO and DAOP [8] indi-cates that the cure reaction varies dependingon the initiator used. In the present work, therheological behaviour during cure of variousconcentrations of DAOP in PPO, the effects ofcomposition on the morphologies of the blendsand thus on the properties were investigated.

2.0 Experimental

2.1 MaterialsThe monomer and the initiator used wereortho-diallyl phthalate (DAOP) and dicumylperoxide (DCP) which were purchased fromAldrich and used as received. Poly (2,5-dimethyl phenylene oxide), PPO was suppliedby GE Plastics as C2000 in a powder form.Before processing, the PPO was dried in anoven at 110˚C for 12 hr. 2.2 Sample preparation The blends are identified by the code

wt%PPO:wt%DAOP/initiator so that 20 PPO:80DAOP/DCP identifies the sample containing 80wt% PPO and 20 wt% DAOP with 3 phr of DCP. Blends of low concentrations of PPO in allylicmonomer (up to 40 wt% PPO) were preparedby direct dissolution in an oven. PPO powderwas first mixed with the monomer at roomtemperature. Then, the mixture was heatedand stirred at 180°C for up to 30 min (depend-ing on the PPO content) until PPO completelydissolved in the monomer. The blend was thencooled to 150°C and DCP was added with rig-orous stirring, Then, the blend was poured intosilicon mould between two microscope slidesand cured at 150° for 8 h before post-cured at200°C for 2 h. For higher concentrations of PPO (50 wt% and60 wt% PPO), melt blending was conducted intwo stages. 60PPO:40DAOP and70PPO:30DAOP blends were first preparedusing a Minilab microextruder and was recircu-lated in the extruder by a pair of taperedscrews and a recycling channel for 5 minbefore being extruded. The screw speed was100 rpm and the pre-set temperature of thebarrel, recycling channel and die was 200°C for60PPO:40DAOP and 220°C for 70PPO:30DAOP.Then the extrudate was cut into about 1-2 cmlengths before crushing the extrudate in thepresence of nitrogen using IKA mill to producea fine powder of the blend. The powder wasmixed at room temperature with the requisiteamount of initiator dissolved in DAOP to pro-duce the 50PPO:50DAOP or 60PPO:40DAOPblends with 3 phr initiator. This mix was thenmelt blended in the twin screw extruder at150°C and screw speed of 100rpm producingthe final homogeneous blends. Although PPO:DAOP/DCP blends could be pre-pared by melt blending, a small but variableamount of allylic polymerization occurs duringthis process. To avoid this complication indetailed studies of the rheological propertiesduring cure, studies were performed on sys-tems that had been solvent blended. Solventblending samples were prepared by dissolvingPPO in chloroform and then mixing with DAOPand initiator, producing 20 wt% of the totalcomponents in chloroform. The solutions werecast into a silicon mould well to produce disksample of about 1-2 mm thick. Then, the sol-vent was evaporated at room temperature fora few hours before further drying under vacu-um at 30°C for 2 days and the at 50°C for 1day (where constant weight was achieved).Mass loss studies on DAOP/initiator aloneshowed that none evaporated using this proce-dure. 2.3 Rheology During CureMultifrequency dynamic rheology studies wereconducted at 0.1, 0.316, 1, 3.16, and 10 Hz at140°C with PPO:DAOP/DCP blends using anARES rheometer (Rheometric Scientific) inorder to monitor the polymerization processes.Samples obtained from solvent blending wereplaced between two steel parallel plates with atop plate diameter of either 8 mm or 15 mmand a gap of 0.5 mm in the rheometer furnacewhich was pre-heated to the temperature ofexperiment. 2.4 Dynamic mechanical thermal analysis(DMTA)A Rheometric Scientific Mark IV model dynam-ic mechanical thermal analyzer (DMTA) wasused in dual cantilever bending mode to meas-ure the glass transition temperature (Tg) ofvarious concentrations of cured PPO:DAOP/ini-tiator blends over a temperature range of 25°Cto 300°C at 2°C/min at 1 Hz. The bar type

specimen had dimensions of 1.5 mm × 5.0 mm× 20 mm and was formed in silicon mouldscured at 150°C for 8 h before post-curing at200°C for 2 h. 2.4 SEMThe morphology of the blends was studied byexamining the fracture surfaces by using SEM(FEI Quanta 3D FEG-SEM) at an operating volt-age of 15 kV. The specimens were freeze frac-tured using liquid nitrogen and then the frac-ture surface was either un-etched or etched inchloroform (for 30 min) to remove the contin-uous phase (PPO phase) from the blends.

3.0 Results and Discussion

3.1 Rheology During CureRheological studies during cure were conduct-ed on the blends of DAOP-DCP and variousconcentrations of PPO and DAOP with DCP asan initiator. Figure 1 shows the variation of G′and G′′ (at 1 Hz) and tan δ (at various frequen-cies) with time of DAOP-DCP at 140°C. It canbe seen that in the early stages of cure, bothmodulii are very low (about 0.1 Pa) and arevery scattered since the material is still a lowviscosity liquid but at 500 s, the G′ increasesrapidly (with G′ exceeding the G′′) due toincrease in the molecular weight of the grow-ing chain and then the build up in the threedimensional network. Then the G′ graduallylevels off and reaches a rubbery plateau of1MPa (at approx. 1000s - see Figure 1) andthen finally, G′ rises to above 10 MPa (atapprox. 1700s) as the material enters theglassy state. Even though 8 mm rheometryplates were used to collect this data, the com-pliance in the instruments components result-ed in overestimates of the strain and so themeasured modulii were lower than thoseexpected of a material near its glassy state(100MPa to 1000MPa).In the early stages of cure, the tanδ valueswere quite high suggesting a viscoelastic liquidstate of the sample but the values are quitescattered and reveal no significant variation oftan δ with frequency (Figure 1). Then, after¬400 s, tan δ began to reduce and approachalmost a constant value at 500 s correspon-ding to the point when the real modulus start-ed to increase. The stage where tan δ is inde-pendent of frequency (often known as the tanδ crossover) is the Winter-Chambon criterionfor gelation [9] and this is not very distinct inFigure 1 due to the low modulus and thus lowtorque of the system at the start ofpolymerization. However a tan δ crossoverappears to occur at ca. 480 s and this is lessthan 5% different from an operational gel pointdefinition [10] which taken from the pointwhere G′ reach 10 Pa (500 s) suggesting thefirst formation of a network. Surprisingly, thedependence of tan δ on frequency just beforeand after gelation is not in accord with the selfsimilarity theory [9] because tan δ shoulddecrease with increased frequency before gela-tion and show the reverse behaviour after gela-tion - the reason for this is not understood buthas also been observed by Varley [11]. Near1700 s the tan δ exhibits a maximum whichshifts to longer curing times with decreasingfrequency suggesting vitrification [10, 11].Additional evidence of vitrification is given bythe logarithmic plot of the real modulus whichshows an inflection corresponding to the tan δmaximum and a rise of the modulus towards aglass-like value.

The gelation time, taken from the time of thetan δ crossover occurs and the time ofvitrification, obtained when tan δ (at 1 Hz)passed through a maximum for various con-centrations of PPO:DAOP/DCP is given in Table1. The tabulated data on gelation and vitrifica-tion (Table 1) shows that the gel timedetermined by the tan δ crossover did not varymuch with PPO content up to 30 wt%PPO butsuddenly increased for 40 wt%PPO whichmight be due to the DAOP being the continu-ous phase in the former but being bi-continu-ous or phase inverted morphology (i.e. dis-persed particles) in the latter which significant-ly reduces gelation of the global blend. Anotherpossible reason for the significantly highergelation time in the presence 40 wt%PPO isthat the Winter-Chambon criteria [9] might notbe applicable for the system of more than 30wt%PPO because these materials are non-homogeneous whereas the Winter-Chambongelation theory was defined for homogeneouspolymer networks [11]. As can be seen fromthe Table 1, the time to vitrify (i.e. reach theglass transition) is raised with increasing PPOcontent suggesting slower reaction. Theincreasing time to vitrify with increasing PPOcontent is expected since previous studies ondynamic DSC [8] of the blends indicates thatthe cure reaction is delayed in the presence ofhigher PPO content.

3.2 Dynamic mechanical propertiesDynamic mechanical studies were conductedon the sample of PPO and DAOP-DCP blendsprepared by melt blending in order to investi-gate the glass transition and rubbery regions ofthe blends after cure (Figure 2). After the glasstransition, the modulus of pure PPO continuesto decrease as the temperature is raised asexpected of an uncrosslinked polymer but sur

prisingly all of the blend samples exhibit a rub-bery modulus plateau, which indicates that thematrix is crosslinked. On the other hand, asexpected and in general accord with the theo-ry of rubber elasticity, the rubbery modulus ofthe cured blends are lower than that for pureDAOP-DCP and continuously decreases withincreasing PPO content because the PPOdilutes the concentration of crosslinks providedby the polymerized DAOP. With increasing PPOcontent (e.g. 30 wt%PPO), the storage modu-lus exhibits a two-step decrease in E′ (Figure 2)suggesting the presence of two phases andonly partial miscibility of the components. Thisis caused by the curing reaction of the poly-DAOP which reduces the entropy of mixingthus causing demixing of the PPO and DAOPblends.

Further evidence for phase separation in theblends is observed by the presence of two tanδ transitions, one with a high damping peakbetween 150°C to 200°C and a smaller tan δshoulder around 250°C. It can be seen that thetan δ maximum of this smaller relaxation riseswith increasing PPO content and it occurs at atemperature close to the Tg of pristine PPOsuggesting that this transition due to a PPO-rich phase. The lower temperature peak isclose to that for pure poly-DAOP and so can beattributed to a DAOP-rich polymer phase. Thevariation of Tg taken from the maximum in tanδ (see Table 2) indicates that the Tg of theblends are in-between both pure componentsbut it does not show a systematic pattern sug-gesting a complex effect of plasticization andcrosslinking. The maximum tan δ value for thelower temperature relaxation does not show amonotonic variation but also tends to increasewith the PPO content. This may appear count-er-intuitive but could be due to the effect of the

presence of PPO in this DAOP-rich phase onthe tan δ value.The Tgs of the blends are lower than the Tg ofpristine PPO (250°C) suggesting that the pres-ence of DAOP reduces the heat resistanceproperties of PPO even though it can success-fully improve the processibility of the PPO. Thismight be due to the presence of unpolymerizedmonomer, as suggested by the incomplete cureof DAOP in the blends [8] which can acts as aplasticizer. However, it should be noted that theTg of the blends were considerably higher thanthe Tg of the uncured blends because the Tg

were raised by crosslinking. Post-curing at200°C for 2 hrs was also applied to the curedsamples (Table 2). In each case, post-curingresulted in either a small (by 5-10°C) orinsignificant changes in the Tg and the rubberymodulus exhibited insignificant changes com-pared with the samples that had not beenpostcured suggesting that the only smallamounts of additional crosslinking of DAOPoccurred with the postcure step.

3.3 SEMThe phase separation and variation of morphol-ogy with increasing PPO content in the curedPPO:DAOP blends as revealed by SEM are illus-trated in Figure 3. In the blend of 20 wt%PPO,particles of 2 m diameter are clearlyrevealed on the un-etched surface and theseparticles are transformed into holes after etch-ing which also suggests island morphology withspherical PPO dispersed phases distributedquite well in poly-DAOP-rich continuous phase.Cured blend of 40PPO:60DAOP/DCP exhibits arough surface when un-etched, but after etch-ing they exhibit a smoother surface with noobvious holes suggesting a bi-continuousstructure of the blends.

In the presence of 50 wt%PPO, the unetchedsample had a rough surface but this was quiteunlike the surfaces found for blends with 10-30wt% PPO which had particles embedded in thematrix. On etching, the 50PPO:50DAOP/DCPsample exhibited a smooth surface with holesranging from sub-micron to 3m diameters.Such a morphology could result from a phaseinversion morphology where PPO is the primarycomponent of the continuous phase and curedDAOP constitutes the major component of thedispersed phase, and the holes in the surfacecould be caused by the dissolution of the PPO-rich matrix surrounding the DAOP-rich parti-cles.

From these SEM observations, it can be con-cluded that the phase inversion occurs withmore than 40 wt% PPO, which is a little high-er than found for the PPO:DGEBA-diamine sys-tem [2] where the phase inversion normallyoccurred at about 30 wt%PPO might be due tothe nature of polymerization of allylic monomerwhere the monomer undergoes chain growthpolymerization with a very slow reaction rate.

4.0 Conclusions

Dynamic rheology of PPO:DAOP/DCP indicatesthat the gelation time rises with increasing PPOcontent. This retardation of gelation is lesswhen DAOP is the continuous phase but the geltime was significantly increased in systemswith bi-continuous (40 wt%PPO) or phaseinverted morphology due to dilution effect ordue to inapplicability of the Winter-Chamboncriteria on the inhomogeneous phase structure. Dynamic mechanical thermal analysis ofPPO:DAOP/DCP showed the occurrence ofphase separation with two Tgs in between thepure components. The Tgs of DAOP-rich andPPO-rich phases did not show a systematic pat-tern due to the complex effect of crosslinkingand plasticization. SEM observation on the blends ofPPO:DAOP/DCP indicated phase separatedstructure with a bi-continuous morphology inthe presence of 40 wt%PPO. The phase invert-ed morphology for the system occurred at ahigher PPO content compared to that alwaysreported for PPO in either step growth or chaingrowth epoxies may be due to the nature ofDAOP polymerization.

INTRODUCTION

Persistent phosphors can emit light for a longtime from seconds to many hours after theexcitation has ended. The irradiation used maybe UV, visible light, X-ray, gamma radiation andsunlight.Persistent luminescence has intrigued peoplefor hundreds of years. The situation drasticallychanged about 16 years ago when Matsuzawaet al. discovered bright and long-lasting lumi-nescence in SrAl2O4:Eu,Dy [1]. By codoping thegreen-emitting phosphor SrAl2O4:Eu2+ (alreadyshowing a relatively strong and long-lastingafterglow by itself [2]) with the rare earth ele-ment dysprosium (Dy3+), they were able to cre-ate a material that emit bright light for hoursafter ending the excitation ended (simultane-ously and independently, Takasaki et al. report-ed similar results [3]). They found an afterglowwith both a far higher initial intensity and amuch longer lifetime compared to traditionalZnS:Cu,Co. These investigations have led to arenewed research interest, and it promoted theuse of these green-emitting persistent phos-phors in signalization, glow-in-the-dark toys,emergency signs, dials and displays, textileprinting, medical diagnostics, and many otherapplications. Applications of persistent lumi-nescence phosphors are rapidly expanding.In this article we propose a new direction instudy and application of these materials,namely underwater investigation of persistentluminescence in real sea conditions.

EXPERIMENTAL PROCEDURES

Artificial rock and block made of steel slaghybrid matrix were developed recently in Japan[4,5]. We proposed experimental artificial glowto be made from concrete and sand to providehard surface. The main goal of these reefs is tocultivate the algae in future and to attract thefish. For this purpose the artificial block mustbe luminescent and preferably excite the greenlight. The persistent phosphor SrAl2O4:Eu2+,Dy3+ as a phosphorescence material and poly-mer epoxy as a coating layer are proposed.Strontium aluminate phosphor doped with Eu2+

and co-doped with Dy3+ SrAl2O4:Eu2+, Dy3+ wereprepared by solid state reaction approach usingstrontium carbonate (SrCO3; Aldrich, 99.9 %),aluminum oxide (Al2O3), europium oxide(Eu2O3; Aldrich, 99.99 %) and dysprosiumoxide (Dy2O3; Aldrich, 99.99 %) as the startingmaterials. Small amount (0.2 mol %) of H3BO3

was used as flux. Prior to heating at 1250ºC,the reagents were ground using a ball mill toform a homogeneous mixture. First, the drymilling was used for 30 minutes and then con-tinued by wet-mixing machine for 30 minutes.The resulting slurry was dried at 150°C for 3

hours to remove the water content. After fullydried, the mixed white powder was placed in asmall alumina crucible and then fired at 1250°Cfor 2 hours under a mild reducing atmosphere.Graphite crucible was used to create the reduc-ing atmosphere and to ensure complete reduc-tion of Eu3+ to Eu2+ and to crystallize and formthe luminescence centers. The mixing – millingprocess to get smaller particle size and homog-enous mixture, was used after calcination.When excited by UV or sunlight this phosphorshows bright green luminescence (Fig.1).

In this study, an epoxy layer of SrAl2O4:Eu2+,Dy3+ phosphor were deposited on reef surfaceby brushing technique. Some amount of mixedpolymers Epoxy DEN 431 and hardener poly-etheramine D230 were prepared and 30 – 40wt% of SrAl2O4:Eu2+, Dy3+ phosphor pigmentwere added to produce a high glowing intensi-ty. After precise weighing of all materials, slipmixture was manually mixing to homogenizedthe epoxy solution and phosphor pigments.This solution was applied onto reef surface bybrushing technique. The epoxy layer ofSrAl2O4:Eu2+, Dy3+ - reef surface interactionstook place during the curing process at 100ºCfor 1 h. The final artificial block is shown inFig.2.

The morphology and structure of the as heat-ed products were studied using XRD Bruker, D8Advance X-ray Diffractometer with Cu-Kα radi-ation of wavelength 1.54 Å .Data have beencollected by step-scanning 2θ from 10° to 90°and 0.034 s counting time at each step at roomtemperature. The morphology was observedusing a Zeiss Supra 35VP field emission scan-ning electron microscope. The photolumines-cence excitation and emission spectra wererecorded using the IHR 550 UV FluorescenceSpectrometer Horiba Jobin Yvon. All the sam-ples were exicited using 325 nm radiation froma pulsed Xenon lamp 450 W. The emissionspectra were registered in the wavelengthsrange of 350 to 625 nm. The detailed results ofthese experiments are given in our previousarticles [6-8].

RESULTS AND DISCUSSION

The underwater experiments were carried outin Pulau Payar, Malaysia. First, the artificialblocks covered with SrAl2O4:Eu2+, Dy3+ andexcited by sunlight were placed on the sea bedwith different reef (agropora corals, rocks,sand) and different depth from 2 up to 6meters. Fig.3 shows the process of installationartificial luminescent block on real stone in thesea at the depth about 5 meters.

Next step was the underwater luminescenceinvestigations. All blocks showed the brightgreen luminescence from all the places inde-pendently of relief and deep. One of the exam-ples is demonstrated in Fig.4.

After a few minutes the fishes showed interestin new luminescent object and gatheredaround it (Fig.5)

Finally, the black-tip shark was also attracted tothe luminescence object and came near ourartificial sample (Fig.6)

CONCLUSIONS

First the experiments with artificial stone cov-ered by SrAl2O4:Eu2+, Dy3+ were carried out inreal sea conditions in Pulau Payar Marine Park.Strong and bright green luminescence wasobserved and registered under the water. Thefishes were attracted to the light of the artifi-cial reef.

Importance of Coal as Energy Resourcesfor Sustainable Development in Malaysia

K. K. CheangKamar Shah Ariffin

Introduction:It is estimated that more than 2 billion peopleor almost one third of the world’s populationhave no access to modern energy services, andunfortunately, the majority of this 2 billion peo-ple live in the Asia-Pacific region (8th APECCoal Flow Seminar 2002). Since energy is cru-cial in achieving the goals of sustainable devel-opment, greater efforts need to be taken toimplement policies, strategies and action plansthat will ensure these 2 billion people haveaccess to adequate and affordable energy sup-ply. At the same time, the directions of sustain-able development also require that plans toprovide greater access to energy supply, beimplemented with a minimum compromise onenvironmental quality. This would be one of thegreatest challenges facing us in this new mil-lennium.

Malaysia’s National Energy Policy in the comingyears will be firstly, to ensure the security ofenergy supply, with no major disruption to var-ious industries, as well as to the individualhouseholds in Malaysia, and secondly, tostrengthen energy security through regionalcooperation. Hence, Malaysia is expected tofully support inter- and intraregional trade andmultilateral-agreements, in various aspects ofthe energy supply chain, including cross borderinterconnection efforts such as Trans-ASEANGas Pipeline and the ASEAN Power grid.

Malaysia also remains committed to the targetsof sustainable development and measures willbe taken to ensure that the production and uti-lization of coal will meet the environmentalstandards of Malaysia. Clean-coal technology,which will include among others, electrostaticprecipitators (for particulate emission) and fluegas de-sulphurization for emission control, willbe utilized in the new power and cement plantsto ensure environmental standards are met.Carbon dioxide emissions from coal-firedpower plants will also grow at 4.1% per year toreach 98 million Mt in Malaysia and 171 millionMt in Indonesia by 2020. Today, both postcombustion as well as pre-combustion captureof CO2 and SO2 is available with adsorptiontechnology for new plants in Malaysia andIndonesia (Martunus et al.,2008). With theright technology, the process of coal extraction,movement and more efficient combustion sys-tem, will help to reduce the environmental con-cerns associated with the use of coal for gen-erating electricity.

However, what is more important in the direc-tion of our recent studies, is that we shouldonly select bituminous coal imported fromIndonesia with low sulfur and ash content butrelatively high gcv (6000-7000 kcal/kg), toreduce the amount of SO2 and ash contents atthe very source itself. This would also reducethe cost of transporting these componentspresent in coal, normally as pyrite and clays

respectively. The maximum amount of claysmay reach as high as 15-18% (arb) and mois-ture may be another 10-18% (maximum), or atotal of 25-36%. In a 60,000 Mt coal shipmentfrom Kalimantan to Malaysia for example, thismay work out to be 15,000-21,600 Mt of claysand water being transported using extra hydro-carbon fuel.

Malaysia’s Energy Mix Policy:

In Malaysia, at 2005 production levels andenergy generation mix (Table 1), oil reservesare dwindling and expected to last another 20years, while natural gas reserves are expectedto last another 33 years only. Contributionsfrom other sources of energy such as hydro-electricity (5-10% despite cutting down a lot oftrees and flooding of river valleys), biomass,solar (several solar panel plants have been setup, but mostly for export), wind and nuclearare still relatively small. It is crucial for us todevelop contingency plans for the supply andutilization of coal as a mineral energy resourcefor the next 20-30 years. The Malaysian government’s policy is to phaseout oil, and reduce the dependency on naturalgas to approximately 45%, while coal andhydroelectricity will have to contribute almost45%, and 10% respectively to 2030, until newpower sources are in place. Even the utilizationof solar panels will require a very large flatarea, which is uninhibited and well-guarded,which is exposed to the sun most time of theyear, in order to garner the sun’s energy.Malaysia will become a net energy importer by2030, and gas will be mostly exported to Japanand Korea due to the higher price it can com-

mand in the regional market. Malaysia isexpected to consume 35 million Mt of coal,whereas our neighbor Indonesia will take up75 million Mt of coal respectively by 2020.

Malaysia’s Coal Production:In 2012, coal production from Malaysian minesis reported to be 2.4 million Mt, while importsare in the region of 19.9 million Mt, mostlyfrom Indonesia (72%), Australia (13%) and S.Africa (12%). The total consumption of 22.3million Mt is mostly in power plants (19.0 mil-lion Mt) and another 3.3 million Mt for indus-tries such as cement, steel and aluminum.Growth in coal demand is approximately 10%per year through 2030.The Merit-Pila Coal Field in Sarawak, which isone of the largest and main sources of coalsupply in the country, has coal characterized ashaving moderate ash content and moisture,very low sulphur and gross calorific values ofabout 5000 to 6000 (Table 2). This area’sreserve is estimated to be about 300-385 mil-lion tonnes of which 10% may be mined byopen cast method.

Another major field is the Mukah-Balingancoalfield, with a reserve at about 270 milliontonnes. The coal is of lignite with high mois-ture, low sulphur, low to moderate ash contentand a gross calorific value of about 5000-5500kcal/ kg. Due to its high moisture content andlow calorific value, the coal from this area isbest suited for mine-mouth power plants andfor coal briquettes. Production is just beginningin 2012.The Silantek coal field contains reserve of 60million tonnes with coal type ranging from bitu-

minous to anthracite and semi-anthracite hav-ing low to medium volatiles, low ash, very lowsulphur and a high gross calorific value ofabout 7000 to 8000 per kg. Some of the coalfrom this area has good coking properties.Production is still relatively small.

Potential Coalfields:The Bintulu coalfield is estimated to have areserve at 20 million tonnes of low ash and ahigh gross calorific value of 7000 to 7500 perkg. Due to its high heating value and closeproximity to a deep-sea port, this coalfieldoffers great potential for further development.In the state of Sabah, coal is known to occur atseveral places, including the Maliau andMalibau basins in south-central Sabah and theSilimpopon and Labuan areas. Maliau coalfieldhas shown great potential, having good qualitycoal and an inferred reserve of 215 milliontonnes. However, this area has been gazettedas Maliau Basin Conservation Area in 1998 bythe Sabah State Government. Malibau coal-fields have a reserve of 26 million tonnes andSilimpopon 14 million tonnes with potential forunderground mining.

Technology for Sequestration of CO2:Fossil fuel such as petroleum, natural gas,shale gas and coal/lignite are still the mostimportant energy sources with almost no otheralternate. CO2 is also one of the major sourcesfor green-house gases CO2 that are assumedto cause global warming. The overall efficiencyof a power plant is significantly reduced if CO2

is captured from flue gas. So far the only reli-able methods for reducing CO2 emissions are adecrease of fuel consumption, increase inprocess efficiency, use of lower carbon fuelssuch as gas, enhancing the natural sinks forCO2 such as jungles/forests, soil, lakes andoceans which drawdown CO2 from the atmos-phere, or to use energy sources with very lowor neutral CO2 emissions such as biomass,wind or nuclear energy.

Another way is to understand the properties ofcoal imported (~90%) into the country andselecting the ones with the lowest sulfur, ashand moisture contents. Luckily, technologiessuch as solvent absorption, physical absorp-tion, membrane and cryogenic fractionationsystems are also available for the sequestrationof CO2. Coal gasification is another way to pro-duce clean fuel in the future. As such for thepresent, coal would still be a sustainable ener-gy resource for Malaysia until such times whencheaper and more practical alternatives areavailable. We must remember that without arelatively low economical energy, we cannotrun any engineering equipment or projectcompetitively, let alone having the luxury ofturning on our lights or heater with the flickerof a switch.

Coal Resource Training at USM:The Mineral Resources Engineering Program atthe School of Materials and Mineral ResourcesEngineering is uniquely positioned as the onlyschool in the country that provides the basictraining for the exploration, evaluation, miningand processing of coal and other mineralresources for engineers and the developmentof Malaysia towards industrialization. The pro-gram has also attracted graduate studentsfrom ASEAN countries such as Laos, Cambodia,Thailand and Indonesia. Large mining compa-nies such as P.T. Bayan Resources (with US$5billion capitalization) has also offered to pro-

vide industrial training, as well as recruitmentof engineers at their more than 8 mining sitesin Kalimantan (top notch facilities) with allexpenses paid. While other industries are inrecession, the coal mining industry is still fairlyrobust, generating jobs not only for mining,but also for transport (large shipments of coalaround the region) and related equipment sup-pliers and civil works with opening of roads andports for the many towns in the region. It isenvisaged that in the foreseeable future theimportance of coal as a sustainable energyresource in Malaysia will be very bright.

Plastics are widely usedmaterial due to their inert properties. The major problems we are facing today withPlastic are non-degradable, toxic-effect humanhealth, harmful components, waste manage-ment problem and environmental issuesThe continuous increase of consumer interestin quality, convenience and food quality hasencouraged the production of edible plasticfrom natural polymer, such as starch or poly-saccharides. In this invention a new EdiblePlastic based on Sago starch was produced. Sago starch was used because it is the higheststarch producer among all starches crops ofthe world, lowest cost compared with otherstarches, widely available and good film form-ing.

Importance of Invention∗ To fabricate a new edible plastic from sagostarch.∗ To replace the toxic and non-degradablepetroleum based plastics with edible plastic.∗ To produce the edible plastic using an inex-pensive and novel technology for packagingapplication.

Novelty and Inventiveness∗ An edible plastic due to the incorporation ofstarch, and special additives (CleanEnvironment). ∗ Can be fabricated using a cheap and break-through technology by optimized the formula-tion and processing condition (Save time andmoney).∗ “Ready to use” edible plastic and have bigpotential usage/global application.

IntroductionDue to increasing concerns of hazardouseffects of using tin-lead alloy solders, lead-freesolders and electrical conductive adhesives(ECAs) have been introduced and are consid-ered to be the most promising alternative forinterconnects, which provide the conductivepathways in the electronics industry. ECAs offernumerous advantages over conventional soldertechnology, such as environmental friendly(due to the elimination of the use of lead andflux cleaning), fewer processing steps (whichreduces processing costs), and fine pitch inter-connect capabilities (which enables the minia-turization of the electronic devices). ECAsmainly consist of an organic or polymeric resinand a metal filler. Currently, the electronicsindustry uses ECAs with micron-sized silverflakes in epoxy resin. However, the advantagesof the nano-sized silver filler have attractedboth academic and industrial interest in furtherinvestigating the potential of these materials toreplace the micron filler.

InnovationSilver nanoparticles were synthesized via thereduction of silver nitrate (AgNO3) by trisodiumcitrate (C6H5O7Na3) and a surfactant. It wasfound that, particles with polygon shapes,good dispersion, and narrow particle size distri-bution of silver nanoparticles were produced byoptimizing the synthesis processing parame-ters.

ProductECA with a better particle distribution of the as-synthesized silver nanoparticles showed aremarkable improvement in electrical conduc-tivity as compared to commercial silvernanoparticles and silver flake.

TEMPERATURE CONTROLLER FOR HEAT-ED GLASSHeated glass panes have been used in com-mercial refrigeration doors for many years toavoid formation of fog on the glass surfaceowing to the temperature differences occurredin between the internal and external environ-ment. Considering that glass is an insulatingmaterial by itself, the glass surface has to becoated with a layer of resistive material, inorder to conduct the electric and generate suf-ficient heat to avoid vapor condensation. Thetemperature of the glass pane is preferablyabove dew point temperature of the surround-ing ambient air to prevent fogging onto theglass pane. Generally, coatings used in glasspane of refrigerator are known as TransparentConductive Oxides (TCOs). Relying on thethickness of the coating material and type ofcoating material as well as size of the glasspane, an electric current of specified amounthas to be supplied in order to maintain theglass pane temperature while not overheatingthe glass pane at the same time. Consideringthat main electric supply always has highervoltage than the voltage actually needed forheating the glass pane, the refrigerator nor-mally includes a circuit to conduct a process forstepping down the voltage. This product is acontrol circuit capable of proportionally supply-ing electrical current from an AC power supplyto a glass pane coated with transparent con-ductive oxides on refrigerator comprising aTRIAC electrically gating the voltage to be sup-plied to the glass pane; and micro-controllerconfigured to fire an electrical pulse to theTRIAC after a pre-determined delayed durationonce detecting zero crossing of each phase ofthe AC. This product can also be used for a dif-ferent size of refrigerator door by setting theselector jumper to the predetermined location.Furthermore, the program in the programma-ble interface controller (PIC) will automaticallydetect the frequency of the AC voltage (for adifferent country) and will supply the requiredvoltage level accordingly.
