The micro-scale Al particles prepared by ball milling and vitamin B12 as common pharmaceutical composed a new combination reagent for hydrodebromination with low-cost and high reactivity.

Application of intermittent ball milling to enzymatic

Hydrolysis of lignocellulosic biomass is important for isolation of glucose in a biorefinery. In this research, intermittentball millingwas applied to facilitate and enhance enzymatic hydrolysis of dilute acid-pretreated lignocellulosic biomass, with the highest glucose yield of 66.5% at a low enzyme dose (10 FPU g −1 glucan) over 24h. In comparison, the yield for the typical liquid-state ...

The mechanism of polystyrene microplastics to affect

Nov 05, 2020· We previously prepared polystyrene microplastic particles (PS-MP) byball millingand used them to adsorb As (III) in pure water. The results showed that PS-MP can adsorb As (III) in ultrapure water through hydrogen bonding, and the adsorption amount can reach 1 mg g −1. The adsorption reached steady-state in about 1200 min, and a pseudo-secondary model adequately described the …
