Fast and Selective Dehydrogenative C–H/C–H Arylation Using ...

A fast and site-selective biaryl synthesis via dehydrogenative C–H/C–H arylation in a ball mill was developed. In this paper, both electron-deficient oximes and electron-rich anilides quickly and under mild conditions provided arylation with various arenes to give the biaryl products in high-level selectivity. Given the solventless mechanochemical conditions, the transformation obviated ...

The cold spraying (CS) process was applied to deposit coatings using the AlCoNiFeCrTi high-entropy alloy (HEA) powder. The HEA powder was produced by short-time mechanical alloying (MA) of an equiatomic mixture in a planetary-ball mill followed by annealing at 1200°C and grinding of the resultant agglomerates. X-ray diffraction and microstructural analyses were employed to study the …

Ball Mills - The Ceramic Shop

Ball mills can be used to further break down or refine a single material, or you can place multiple materials into a ball mill jar to mix as you pulverize -- this is a very common industrial solution for mixing glazes that require the smallest of mesh sizes. Ball mills basically function like a mortar and pestle, but on a much larger scale.
