Cesium-exchanged heteropolyacid (Cs(x)H3.0-xPW12O40) was impregnated onto activated carbon aerogel (ACA) with a variation of cesium content (X = 2.0, 2.3, 2.5, 2.7, and 3.0) in order to provide acid sites to ACA. Palladium catalysts were then supported on Cs(x)H3.0-xPW12O40-impregnated activated carbon aerogel (Pd/Cs(…
The RERTR Program (Reduced Enrichment in Research and Test Reactors) is an attempt to utilize uranium fuel enriched below 20% for nuclear research reactors. Since the program was launched by the United States in 1978, the International Atomic Energy Agency (IAEA) has recommended that UxSiy alloys, particularly U3Si2 a…
Poly-Silicon nanowire (Poly-Si-NW) simulations are very important field of nanotechnology and nanostructures; in this paper presented review in general nanowire and it applications such as thermoelectric device (TED) has potential applications in areas such as chip level cooling/ energy harvesting and many more applic…
Perovskite lanthanum manganites, especially those doped LaMnO3 (LMO), have shown potentials for applications in magnetic electronic functional materials. Partial substitution of La ion with divalent ions or Mn ion with trivalent ions gives rise to new properties. Substituted LMO has ability for absorbing electromagnet…
Nanoporous silicon based explosive formulations are currently being explored, with an aim of replacing lead based primary explosives. Nanoporous silicon combines with oxidisers to form energetic mixtures. It is known that the reactivity of such explosive formulations is influenced by the amount and type of oxidiser us…
The synthetic dyes are a refractory and poisonous material. Most of industrial textile today used the synthetic dyes that can be dangerous to the environment because of the colored wastewater produced from their processes. This study concentrates on the application of Advanced Oxidation Processes (AOPs) for synthetic…
The effects of carbon black (CB), silica and calcium carbonate (CaCO3) in virgin polyethylene (vPE)/recycle polyethylene (rPE)/ethylene propylene diene terpolymer (EPDM) blends were investigated. rPE was melt blended with EPDM in different ratio by using a Haake Rheomix. The characterization such as swelling analysis…
In the present work, ZnO nanorods array were successfully grown on ITO substrate via chemical bath deposition method (CBD). The seeding solution was prepared at low temperature (0°C) using zinc nitrate tetrahydrate and hexamethylenetetramine. The as-deposited ZnO nanorods were hexagonal wurtzite structure growing vert…
PbSn composites have been prepared by powder metallurgy for Advance Energy Transfer Bullet Application. Sn compositions was variety 5, 10, 15wt%. The compacting pressure performed at 10, 15, and 20 MPa. Temperature and holding time of sintering constantly in 150OC for 2 hours. The microstructure and mechanical perform…
Silicon carbide reinforced copper matrix (Cu-SiCp) composites are highly rated as thermal management materials due to their high thermal conductivity and low thermal expansion properties. However, the Cu-SiCp composites fabricated via the conventional powder metallurgy methods have substandard properties due to the we…
The effect of space-holder content on the porosity of sintered copper that was fabricated by powder metallurgy technique has been investigated. Carbamide was used as space-holder and the content selected was 10 wt. %, 20 wt. % and 30 wt. %. A roll mill was used to mix the copper powder and the carbamide particles with…
Pd (en)2Cl2 can be intercalated into graphite oxide layers with high efficiency. The Pd (en)22+ intercalated graphite oxide was firstly synthesized by mixture reaction of Pd (en)2Cl2 and graphite oxide, then it was reduced in solution with NaBH4 and thereafter the graphene/Pd nanosized particle composites were obtaine…
Organic light-emitting diodes (OLEDs) were fabricated containing guest molecule of Tris (8-hydroxyquinoline) aluminum (Alq3) blend with host molecules of N,N-diphenyl-N,N-bis (3-methylphenyl)-1,1-biphenyl-4,4-diamine (TPD) and 2-(4-biphenylyl)-5-phenyl-1,3,4-oxadiazole (PBD) small molecules. Optical, photoluminescence…
In this paper, a formula for the calculation of carbon content during austenitizing of cast iron was deduced, considering the effect of silicon content on the heat treatment parameter. According to this formula, the carbon content of the austenite in a certain austenization temperature for a cast iron with given compo…
Transformation optics-based innovative cloak which combines the virtues of both internal and external cloaks to enable arbitrary multi-objects hidden with visions and movements was first proposed by Huang et al. [Appl. Phys. Lett.101, 151901 (2012)]. But it is rather difficult to implement in practice, for the require…
The combustion of paper mill sludge and bituminous coal in air was analyzed using a thermogravimetric instrument. TG and DTG curves for the blends lies between that of the individual fuels, and the main combustion characteristics of blends depended on individual fuels and followed the weighted average. As the blending…
A composite comprising cyclopentyl trisilanol silsesquioxanes (CpSSQ(OH)3) and 50% epoxidized natural rubber (ENR-50) was prepared at reflux temperature employed hydrochloric acid (HCl) as catalyst. HCl was found to be an effective catalyst to promote ring opening reaction of ENR-50 and tailored CpSSQ(OH)3 to the ENR-…
The gold nanoparticles film has been successfully formed on the silicon wafer by self-assembled method. The gold colliods were prepared by chemical reduction method where sodium citrate (act as the reducing, capping and stabilizing agent) were added into the boiling 50ml of 0.01% tetrachloroauria acid (HAuCl4) solutio…
The biocomposites were prepared by using kenaf bast fiber mat as reinforcing materials at different percentage. The kenaf bast fiber was treated with alkaline at different sodium hydroxide (NaOH) percentage. From the results obtained, surface morphology of the treated kenaf bast fiber shows less impurity than untreate…
This research work investigates the influence of the annealing process upon the performance of photo-emissive layer of organic light-emitting diode (OLED).
