Typically, when 2 g of bulk h-BN was used, the production rate of 2D h-BN could reach 0.3 g h −1, which is around 10 times that of a typical ball milling method for preparing amino-functionalized small 2D h-BN sheets . This rate is the highest value reported for h-BN production to date (Supplementary Table S1).

Ultrafine grinding is an environmentally friendly pretreatment that can alter the degree of polymerization, the porosity and the specific surface area of lignocellulosic biomass and can, thus, enhance cellulose hydrolysis. Enzyme adsorption onto the substrate is a prerequisite for the enzymatic hydrolysis process.

The following equation is used to calculate spindle speed: rpm = sfm ÷ diameter × 3.82, where diameter is the cutting tool diameter or the part diameter on a lathe in inches, and 3.82 is a constant that comes from an algebraic simplifica-tion of the more complex formula: rpm = (sfm × 12) ÷ (diameter × π). Because the tool diameter is ...
