Extrusion pretreatment was applied to enhance fermentative methane production from rice straw. The extrusion-pretreated rice straw (EPRS) showed significant particle size reduction, physical properties improvement and volume expansion, as compared to the milling-pretreatment rice straw (MPRS)...

Well-aligned hierarchical TiO2 tubular macrochannel arrays (HTTMAs) with high surface area have been synthesized via a facile one-step ammonia hydrothermal synthesis process without using any structure-directing templates. The typical samples are made of an assembly of macrochannels with uniform...
