Chemical reactions that take place in a ball mill and the absence of bulk reaction solvent present different safety profiles to stirred solution reactions. Herein, we describe steps researcher may better ensure they have considered some hazards measures emerge minimize risk themselves their colleagues.

An experimental study was carried to find out the degradability of black liquor of pulp and paper mill wastewater for biomethanogenesis in continuous stirred tank reactor (CSTR) and followed by activated sludge process (ASP). Continuous stirred tank reactor was used in present study for anaerobic digestion of black liquor, while completely mixed activated sludge system was used for aerobic dige...

The effect of mechanical activation on the leaching and electrochemistry chalcopyrite was investigated in a glycine medium. Leaching experiments were conducted to evaluate particle size (with re-ground sample ball mill) planetary mill for 4 h) dissolution stirred tank reactor. Results show that maximum copper extraction (95.1%) obtained mechanically activated after 12 h 0.4 M solution at 60 °C,...

Herein, novel bioactive glass flakes (BGFs) (45S5 composition), obtained by compression in the liquid phase a stirred media mill, are combined with chitosan (CS) to develop composite membranes using solvent casting for guided bone regeneration (GBR). The incorporation of BGFs endows CS superior bioactivity as evidenced rapid hydroxyapatite formation after 3 days immersion simulated body fluid (...

We investigated a nonlinear advection-diffusion-reaction equation for a passive scalar field. The purpose is to understand how the compressibility can affect the front dynamics and the bulk burning rate. We study two classes of flows: periodic shear flow and cellular flow, analyzing the system by varying the extent of compressibility and the reaction rate. We find that the bulk burning rate v(f...
