Synthesis of high surface area copper trimesate MOF via mechanochemical method
No full textCopper Trimesate Metal-organic framework (MOF), known as CuBTC has attracted a great deal of interest due to its high surface area and moisture stability. In this research, the synthesis of CuBTC MOFs has been carried out successfully using mechanochemical method. The purification method to preserve the high surface area of CuBTC after the synthesis was systematically investigated. It was found that the best method was by drying the samples soon after the synthesis and kept under argon atmosphere. Meanwhile, the purification is more favorable to be conducted just in time before the use of the samples for further applications. The highest BET surface area of CuBTC synthesized using this method was 2011 m2/g. This is the highest reported value for CuBTC synthesized with mechanochemical technique to our knowledge

The Effect of Solvent on the Characteristics of FeBTC MOF as a Potential Heterogenous Catalyst Prepared via Green Mechanochemical Process
No full textIn this study, the synthesis of FeBTC (BTC = 1,3,5-benzenetricarboxylate) also known as MIL-100 (Fe) metal organic framework (MOF) has been carried out successfully using green mechanochemical method (neat grinding and liquid assisted grinding). The effect of solvent used in the synthesis was investigated for the first time to elucidate the physicochemical properties of FeBTC including crystal structure, thermal stability, pore size and specific surface area. The physicochemical properties of all FeBTC obtained in this study were compared to commercial FeBTC (Basolite F-300), characterized using powder X-Ray Diffraction (XRD), Thermogravimetric Analysis (TGA) and nitrogen physisorption isotherms. All Fe-BTC MOF synthesized in this study showed improved textural properties compared to commercial Basolite F-300 such as higher crystallinity, higher surface area and larger pore size. It was found that the best synthesis method was by using the mixture of ethanol and water with equal volume ratio as solvent. The highest BET surface area of FeBTC synthesized using this method was 972 m2/g for FeBTC-EtOH/H2O. This value is 2.3 times higher than the surface area of commercial Basolite F-300 (418 m2/g). FeBTC with higher surface area is expected to have higher catalytic activity which makes this FeBTC an excellent candidate as a heterogenous catalyst for many reactions such as aldol condensation or esterification reaction

Rutting resistance of SMA mixtures incorporating crumb rubber / Herda Yati Katman
Get PDFWith the exponential growth in the number of automobiles in Malaysia in recent years, the problem generated by waste tyres has also increased. Therefore, incorporating waste tyres as an additive in road pavement might be an option to overcome the increase in the number of waste tyres as well as address some of the pavement problems, such as rutting deformation.
Crumb rubber modified binder is acknowledged to provide better rutting resistance. Many research works have been implemented on the effects of chemical additives to further increase the performance of crumb rubber modified binders. Recent studies have shown that the properties of crumb rubber modified binders can be improved by adding crosslinking agents, such as trans-polyoctenamer (TOR) for which the main function is to activate the rubber-bitumen interaction and improve crosslinking.
This study was conducted to determine a method to improve the rutting resistance of SMA 20 bituminous mixtures. Accordingly, different percentages of crumb rubber were added to bitumen using different blending methods (continuous blend and terminal blend) in order to produce different concentrations of crumb rubber modified binder. In addition, a crosslinking agent, namely, trans-polyoctenamer (TOR), was introduced in the crumb rubber modified binder with the intention of further improving the binder properties and minimizing the rutting problem.
In order to analyse the performance of the binders and mixtures as well as to evaluate the relationship of the rutting characteristics between them, a series of binder tests and bituminous mixture tests were performed. In the final analysis, the author found that the binder tests were not adequate to evaluate the rutting characteristics of bituminous mixtures. For instance, in the case of the crumb rubber modified binder prepared using the terminal blend method, most of the binder tests show that the terminal blend binder displays the best performance; however, in respect of the bituminous mixtures it became worse.
To further study the creep behaviour (rutting characteristics) of bituminous mixtures, the dynamic creep test was performed using the universal testing machine (UTM) at different temperatures and stress levels. Finally, the creep behaviour of the specimens was estimated using the Zhou three-stage creep model. The results show that crumb rubber and TOR significantly affected the rutting parameters, especially at high stress levels and temperatures. Moreover, based on the Zhou model, it was concluded that resistance to permanent deformation (rutting resistance) was improved by the application of crumb rubber and TOR.
In addition, multiple linear regression (stepwise method) was used for statistical analysis for which the main objective was to develop an equation (regression model) that could be used for predicting the rutting of the mixtures for all factors engaged. A secondary purpose was to use regression analysis as a means of explaining the causal relationship among the factors (significant level)

Trauma Klas III Ellys dan Davey pada Gigi Insisivus atas Permanen
No full textCedera traumatik merupakan hal yang umum terjadi pada anak, dapat melibatkan gigi desidui maupun gigi permanen. Trauma pada gigi permanen muda sering terjadi pada usia 8 tahun sampai usia 12 tahun. Gigi Insisivus atas yang protrusi (klas II divisi 1). overjet yang lebih dari 4 mm dan penutupan bibir yang tidak sempurna merupakan faktor predisposisi terjadinya trauma.
Trauma klas III Ellys dan Davey dengan pulpa terbuka pada gigi, terjadi 26-92% dari semua cedera trauma pada gigi. Pada saat terjadi trauma kondisi gigi belum sempurna, khususnya di daerah dinding saluran akar dan apikalnya, oleh karena itu tujuan utama perawatan trauma klas III Ellys dan Davey yang kompleks adalah mempertahankan vitalitas pulpa gigi, dan melanjutkan perkembangan sampai pembentukan akar yang sempurna.
Berdasarkan pemeriksaan klinis trauma klas III Ellys dan Davey, untuk gigi yang pulpanya masih vital, dilakukan perawatan apeksogenesis sedangkan gigi yang pulpanya telah nekrosis atau non vital dilakukan perawatan apeksifikasi dengan menggunakan dressing kalsium hidroksida (Ca(OH)2), oleh karena itu sangat perlu untuk mempertahankan vitalitas pulpa gigi dan melanjutkan perkembangan akar yang sempurna.32 HalamanSkripsi Sarjan
