By consideration of unique properties of composite Al2O3-ZrO2 such as high toughness, high wear resistant and relative low thermal expansion, in this study, nanocomposite of Al2O3-ZrO2 was produced by Mechanical activated Self propagating High-temperature Synthesis (MASHS) using laser beam for ignition. First Al and ZrO2 powders were mixed in the mole ratio of 1:1 and milled for 1, 3 and 6 hour...
Introduction: The extended human presence on the Moon will enable astronauts to develop new technologies and harness the Moon's abundant resources to allow manned exploration of more challenging environments [1]. Various approaches to establish permanent outposts on the Moon are being considered by major space agencies and construction companies from USA, Europe, Russia and China. Construction ...
A series of well-defined copolymer brushes, PS-g-P3HT, composed of a hydrophobic coil-like PS backbone and densely grafted rod-like P3HT side chains were successfully synthesized by a combination of the quasiliving Grignard metathesis (GRIM) method, reversible addition–fragmentation chain transfer (RAFT), and click reaction. The molecular weight distribution of the resulting PS-g-P3HT copolymer...
