Mechanochemical activation in planetary ball mills generates energy that is effective for the efficient, solvent-free syntheses of several types of organic molecules, including active pharmaceutical ingredients and diagnostic agents. X-ray-based procedures ...
Direct mechanochemical synthesis of nanostructured CaWO 4 from wolframite and CaO.. Quantitative conversion of wolframite and CaO into CaWO 4 by planetary ball milling.. No need of CaO excess to get complete conversion of wolframite into CaWO 4.. Nanostructured CaWO 4 is easily leachable in alkali solutions at ambient pressure.
The Institute for Technical Chemistry and Environmental Chemistry of the Friedrich-Schiller University of Jena has developed new and improved methods for synthesis strategies using Planetary Mills in the organic synthesis laboratory - without solvents. …
For instance, high energy ball milling is a top-down method using planetary ball mills. To obtain optimized milling parameters in a planetary ball mill, many trials are needed. Hence optimization of the milling parameters through modeling tools is necessary to reach economically efficient and time-saving synthesis of nano-fertilizers.
The mechanochemical synthesis was carried out in a planetary ball mill "Activator 2S" (Activator, Russia). HEBM of hafnium and carbon powders, mixed in a 2:1 M ratio, was accomplished in a nitrogen atmosphere. 18 g of Hf + C powder mixture was placed in a 250 ml stainless steel cylindrical jars with 360 g of stainless-steel balls.

The Strecker reaction between aldehydes or ketones, amines and cyanide to furnish α-aminonitriles was the first reported multicomponent reaction and hence a milestone in the development of organic synthesis.17 Hernández and Bolm have recently disclosed their work on the mechanochemical Strecker reaction (Scheme 3), employing a planetary ball ...
The lack of the rapid and direct synthesis of a perovskite product by a planetary ball mill is attributed to a kinetic limitation associated with difficulties in developing a mill capable of ...
Herein, nano-sized α-Al 2 O 3 powders were successfully synthesized at low temperatures via unidirectional ball milling of Al(OH) 3 and addition of an AlF 3 additive. The effects of the rotational direction in planetary ball milling on the α-phase transformation and morphology of α-Al 2 O 3 were studied. Unidirectional rotation was observed to be significantly more helpful than ...
