Abstract: AbstractA two-stage pretreatment (TSP), namely ultrasonic vibration treatment and solid-solution treatment, is proposed to improve the microstructure and properties of Mg-9Al-1Si alloy before equal-channel angular pressing (ECAP). The ultrasonic vibration treatment could distribute Mg2Si and… read more here.

DOI: 10.3390/en12091715
Abstract: Pretreatment is a necessary step when lignocellulosic biomass is to be converted to simple sugars; however single-stage pretreatment is often insufficient to guarantee full availability of polymeric sugars from raw material to hydrolyzing enzymes. In… read more here.
