Tomislav Friscic and his colleagues have been using the European Synchrotron Radiation Facility which is nestled in the mountains of southeastern France to open up frontiers of mechanochemistry grinding molecules together to promote hydrogen bond associations Photo creadit S Evans G Garner
The use of mechanochemistry addresses these issues8 The process of grinding solid components to induce chemical transformations can be traced back centuries but it has only been in the last twentyfive years that a period of rediscovery in mechanochemistry has begun to take place9 Mechanochemistry
Mechanochemistry conducted by grinding or milling is a powerful strategy for rapid clean and environmentally friendly synthesis of coordination compounds and polymers which avoids bulk solvent and limitations of solutionbased chemistry such as solvolysis and solvent complexation
Mechanochemistry is maturing as a discipline and continuing to grow so it is important to continue understanding the rules governing the system In a mechanochemical reaction the reactants are added into a vessel along with one or more grinding balls and the vessel is shaken at high speeds to facilitate a chemical reaction
In mechanochemistry the emphasis is on the synthesis of new materials respectively the alteration of existing material properties Here it is attempted to break apart the known atomic structure of a material and the links of individual atoms chains or also replacing existing gaps with other material 3This process requires special conditions since in these structures numerous forces are
Mechanochemistry the process of synthesising chemical products using mechanical action has gained attention as a way of doing just that Friščić’s team has gone a step further by also removing the need for socalled grinding media – the tiny balls or pellets used to grind the molecules together
