Nano-forsterite powder made of natural silica sand Nano-forsterite powder with natural silica sand and magnesium powder as the raw materials have been successfully synthesized. The silica sand was purified followed by a coprecipitation process to obtain colloidal silica. The ...
Aluminum – matrix composites prepared by power metallurgical (P/M) process Al/Mg composites fabricated by P/M technique followed by sintering to improve mechanical properties. Interfacial bonding is an important issue in this regard, where metal oxide phases are commonly formed ...
RADAR absorbing materials employing Fe3O4 nanoparticles Stealth technology can in principle be either RAM (radar absorber material) or RAS (radar absorber structure) . RAMs are materials that have reflection loss of <-20 dB (equivalent to the absorption > 99%) with ...
Biogas as a renewable energy Organic substances from household and livestock wastes are raw materials for biogas. Anaerobic decomposition of organic waste that is riched of cellulose by microorganisms (bacteria methanogenesis) produces methane and other gases as by products ...
Zr-based Metallic Glass Oxidation behavior of Zr-based metallic glasses has been studied at temperatures below glass temperature (Tg), crystallization temperature (Tx), and between Tg and Tx in air atmosphere. This behavior affects significantly on the structural stability of the ...
