A promising approach in the selective separation and modification of cellulose from raw biomass under a mild alkali process was proposed. In our study, ball milling was applied to wheat straw prior to alkali treatment. With ball milling, ultrafine powder formed an amorphous microstructure and displayed a level of solubilization in aqueous NaOH higher than that of general ground samples. Alkali ...

Silicon powder ( %, particle size ) was ballmilled in an attritor ballmill at 400 rpm for 30 h in hexane. It was found that slurry of ballmilled silicon in hexane was produced as a result of the milling. This slurry was sprayed into a silica tube at high temperature (800±1100℃) under an argon atmosphere.
