Ball milling liquid nitrogen

liquid nitrogen (LN) and ball milling was developed for the pretreatment of cellulose. Liquid nitrogen was widely used for the frozen treatment of biological samples such as plant tissue to extract intracellular compounds.21 Besides, liquid nitrogen has been applied in the mechanical production of cellulose microfibers.22 Castoldi et al

    Coupled Pretreatment with Liquid Nitrogen and Ball Milling

    Jul 08, 2019 A key problem in the conversion of cellulose into chemicals and fuels is the low product yield from cellulose due to its robust structure. In this work, for the first time, cellulose was pretreated with coupling of liquid nitrogen and ball milling (LN–BM) for cellulose hydrolysis. After the LN–BM treatment, the glucose yield from cellulose by HCl in water increased by almost 2 times and

    Aug 12, 2021 Aug 12, 2021 Yu and Wu studied ball milling under cryogenic conditions by cooling the grinding cell with liquid nitrogen for 10 min before a 2-min ball milling pretreatment. The authors found that cryogenic ball milling of microcrystalline cellulose resulted in a significant reduction in cellulose particle size but only a slight improvement was achieved in

    A novel ultra-cryo milling micronization technique for pharmaceutical powders using liquid nitrogen (LN2 milling) was used to grind phenytoin, a poorly water-soluble drug, to improve its dissolution rate. LN2 milling produced particles that were much finer and more uniform in size and shape than particles produced by jet milling
