The oxygen enriched combustion of diesel engines can reduce smoke emission and increase engine thermal efficiency; however it can also lead to an increase of NO emission. In this paper, experiment was conducted on a turbocharged direct injection diesel engine, and oxygen-enriched and EGR...

High-performance TiO2–polythiophene hybrid solar cells are reported. Metal-free organic dye (D102) is employed to modify the TiO2/polythiophene interface. Results indicate that interfacial engineering and dye engineering are crucial for device performance.

During anaerobic fermentation of waste activated sludge (WAS), the production of short-chain fatty acids (SCFAs), especially propionic acid which is considered as the most preferred carbon source for enhanced biological phosphorus removal, can be improved by controlling the suitable mass ratio...
