A method of adapting a centrifugal machine that is a dual asymmetric centrifugal mixer or a planetary mill, used for mixing materials, for grinding one or more materials; it includes positioning in a container of the machine, non-spherical grinding media, and securing a lid on the opening of the container, wherein the bases of the units of the non-spherical grinding media are prevented from toppling by having a shortest distance between the center of mass of the unit of non-spherical grinding media and a base be less than half of the width of the base; or securing the lid sufficiently near the top of the units of the non-spherical grinding media such that when a unit of the non-spherical grinding media tilts, the unit of the non-spherical grinding media contacts the lid, the lid acting as an obstacle preventing the unit of the non-spherical grinding media from toppling.

Systems for providing centrifugal machines with grinding functionality

A method for the preparation of a metal-organic compound is provided. This method comprises the steps of (a) providing at least one metal precursor, (b) providing at least one bridging organic ligand, and (c) exposing together the metal precursor and the ligand to liquid COor supercritical COas a reaction medium, thereby producing said metal-organic compound.
