Ball milling methide

Aug 11, 2021 The developed ball-milling method enabled large-scale synthesis, that over 4.7 g of Co-SNC can be produced in one pot. In benzylamine coupling reaction, Co-SNC exhibited the highest conversion of 97.5 % with 99 % selectivity toward N-benzylidenebenzylamine in 10 h

In such cases, polysaccharides, lignin, and lignin/carbohydrate complexes cannot be separated according to their molar masses because all these components are depolymerized during ball-milling

    The nature of precursor phenomena in the paraelectric phase of ferroelectrics is one of the main questions to be resolved from a fundamental point of view. Barium titanate (BaTiO3) is one of the most representative perovskite-structured ferroelectrics intensively studied until now. The pretransitional behavior of BaTiO3 single crystal grown using a solid-state crystal growth (SSCG) method was
