Summary: Fourteen kinds of building insulation foam materials (BIFM) were prepared by combining industrial and agroforestry wastes with alkali activator. The properties of BIFM were tested and the effects of Na2O content, sodium silicate modulus, and RHA content on the properties were discussed. The CO2 emissions and energy consumption of BIFM were estimated and compared to traditional insulation materials. The results showed that BIFM had optimum thermal conductivity and beneficial energy and carbon footprint compared to traditional materials.

Summary: A novel method of heating was used in this study to investigate the effect of heating temperature on the strength, pore, and fracture structure of briquette coals. The results showed that the uniaxial compressive strength and elastic modulus of briquette coal first increased and then decreased with heating temperature, while pore size distribution and morphology changed. This study provides a new method that can be applied in physical simulations to prevent disasters caused by coal and gas outburst in coal mines.

Summary: This study compared the effects of microwave heating (MH) and conventional conductive heating (CH) on methane desorption from coal. The results showed that MH had a higher final total desorbed volume of methane compared to CH, and it effectively changed the coal sample's microstructure, reducing methane adsorption, promoting diffusion, and improving permeability. The rapid temperature rise and changes in the coal's microstructure caused by MH were the main reasons for its superior performance in enhancing coalbed methane recovery.

Summary: In this study, a novel hybrid fiber-reinforced material, silk-carbon fiber/epoxy resin composites (SCFECs), was developed using unique silk-carbon fiber core-spun yarns (SCCYs). By strategically placing silk wraps at the carbon fiber bundle-matrix interfaces, the impact strength of SCFECs was significantly improved without compromising their static strength. The optimal impact strengths of SCFECs with 5.6 vol% carbon fiber-5.2 vol% silk and 11.2 vol% carbon fiber-10.4 vol% silk were 50.4 and 64.4 kJ/m(2), respectively, which were about 80% higher than those of neat carbon fiber composites without silk.
