Numerous complex cyclopropenes with unprotected amino and silyl groups, that would need protecting in solution-phase chemistry, were synthesised in high yield. 4. Putting the screw on molecules. A ball mill is not the only way to physically force one or more molecules to react; the twin-screw extruder is another suitable option.

Ball milling is investigated as a method of reducing the leaching concentration (often termed stablilization) of heavy metals in municipal solid waste incineration (MSWI) fly ash. Three heavy metals (Cu, Cr, Pb) loose much of their solubility in leachate by treating fly ash in a planetary ball mill, in which collisions between balls and fly ash drive various physical processes, as well as ...

Mg 0.25 Mn 0.75, prepared through ball milling MgH 2 and Mn powders, is a nanocomposite where the nanometer-sized MgH 2 domains are randomly embedded in a Mn matrix. This sample readily and reversibly absorbs and desorbs deuterium even at a temperature of 200 °C without the addition of any catalysts.

Mechanochemistry using ball mills is a promising technique with applications in organic and inorganic chemistry as well as material sciences [1–4].During ball milling, up to 80 % of the energy that is generated in the mill is dissipated as heat [].This is why measurement and control of the temperature in the ball mills is important, for example, if heat-sensitive products …

Drum Mill TM 300. The TM 300 Drum Mill is used for the preparation of granules and powders. The grinding process is performed either in dry or wet conditions. The drum mill can be operated either as a Ball or as a Rod Mill by using the corresponding module. A sufficient number of balls or rods is required for an effective grinding process.

In the last years, numerous protocols have been published using ball milling for organic synthesis. Compared to other methods such as microwave or ultrasound irradiation and ionic liquids, ball mill chemistry is an economical, and ecofriendly method in organic synthesis that is rather underrepresented in the knowledge of organic chemists. The aim of this review is to …

The reaction with one Pd milling ball (3.6 g) resulted in a low yield (6 %) but a high DP (115) (PPP MM-1, see Table 2). The high energy impact with one milling ball had a high conversion efficiency but only a few possibly reactive collisions occurred. Also, inefficient mixing of the reaction mixture with one ball may have caused the poor yield.
