However, the yield is expected to be improved after optimization of the conditions, because we reported 87% yield in the ball milling of MoS 2 nanosheet with HTP under unoptimized conditions. In addition, we chose amino acid such as alanine, proline and phenylalanine as a bio-related molecule like SC, but much simpler one.
As shown in Fig. 1, ball milling effectively increased adsorption capacity from 5–15 mg/g for unmilled biochars to 100–300 mg/g for BM–biochars (about a 20-fold increase) regardless of different feedstock type and pyrolysis temperature.Both biochar feedstock type and pyrolysis temperature showed strong influence on capacity. For the same feedstock, removal increased in the order ...

Optimization of mill performance by using online ball and pulp measurements Soon after a stop, a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples. Crash stops are difficult to handle. The mill and all feed streams should be stopped simultaneously but, often, they are stopped around about the same time.
