Mechanochemical synthesis of γ-Bi2O3
Solid State Sciences, 2004A series of gamma-Bi2O3 phases doped with Zn, Si, Pb and Fe was prepared by mechanochemical treatment of corresponding oxide mixtures with a nominal composition 6Bi(2)O(3) (.) MOx (MOx = ZnO, SiO2, PbO) and 12Bi(2)O(3) (.) Fe2O3 using high-energy ball mill. The products are characterized by X-ray powder diffraction technique.

Mechanochemical Synthesis of Boroxine-linked Covalent Organic Frameworks.
Angewandte ChemieWe report a rapid, room-temperature mechanochemical synthesis of 2- and 3-dimensional boroxine covalent organic frameworks (COFs), enabled by using trimethylboroxine as a dehydrating additive to overcome the hydrolytic sensitivity of boroxine-based COFs.

Mechanochemical synthesis of polyboronphenylsiloxanes
Polymer, 2020Abstract In the present work, the mechanochemical synthesis of polyboronphenylsiloxanes was carried out. Boron difluoride acetylacetonate and polyphenylsilsesquioxane were used as starting reagents. The products of the syntheses were studied by IR and NMR spectroscopy, elemental and X-ray phase analysis, gel permeation chromatography and MALDI-TOF ...
