Nano-metallic oxide particles have been found to be potentially effective microstructural reinforcements for cement mortar and become a research hotspot in recent years nano-modification technology of building materials. However, different conclusions obtained due various researchers used methods, which resulted deficiency the performance comparison between nano-metallic particles. In present s...

Polymeric nanocomposites are an emerging research topic, as they improve fiber-reinforced composites’ thermo-mechanical and tribological properties. Nanomaterials electrical thermal conductivity provide excellent wear friction resistance to the polymer matrix material. In this work, a systematic study was carried out examine tensile hardness properties of carbon fiber epoxy composite comprising...

Production of butadiene from biomass-based tetrahydrofuran (THF) is explored as an alternative to the existing petroleum-based processes. Metal oxide catalysts have been shown exhibit varying product selectivities when reacted with THF. Among those oxides, ZrO2 showed highest selectivity for butadiene. In contrast, Al2O3 competing retro-Prins products, C3H6 and HCHO. The reasons behind across o...

Series of Copper Ruthenium (Cu-Ru) bimetallic catalysts supported on γ-Al2O3 with different metal loading are prepared and investigated for catalytic wet air oxidation of ammonia to nitrogen. The ammonia decomposition activity was studied at three different temperatures i.e. 150oC, 200oC, and 230 oC and it is found that catalytic activity increases with the increase in temperature along with th...

The present work deals with the mechanical properties of hybrid nanocomposites made epoxy/glass fibre dispersed different weight percentages nano-α-Al2O3 powder . nanoparticles were synthesized by a high energy ball milling technique (60 and 200 nm).. effect size content (wt%) on properties, such as tensile, flexural, interlaminar shear stress (ILSS) hardness was investigated. addition enhanced...

Thermal enhancement of a single mini channel in Proton Exchange Membrane Fuel Cell (PEMFC) cooling plate is numerically investigated. In this study, low concentration of Al2O3 in Water Ethylene Glycol mixtures is used as coolant in single channel of carbon graphite plate to mimic the mini channels in PEMFC cooling plate. A steady and incompressible flow with constant heat flux is assumed in the...

Fuel oil has a deficit every year. Therefore, substitute fuel is needed, which can be obtained more efficiently. One of the alternative fuels that have been widely researched biofuel. Catalytic cracking method producing biofuels such as biogasoline (C5-C9), bioavtur (C10-C15) and green diesel (C16-C22). This research aims to produce by catalytic palm using HCl/γ-Al2O3 HCl/Ni/γ-Al2O3 catalysts (...

Coatings prepared from nanosized powders were obtained by spraying ethanol-based colloidal solutions into a plasma plume. The powders investigated included 40 nm γ -Al2O3, 75 nm 8 wt% Y2O3-ZrO2, and 750 nm 25 wt% CeO2-ZrO2. Spray distances from approximately 50 to 63 mm were required to achieve significant coating deposition. As observed in the TEM, the typical lamella morphology of air plasma ...
