Microwave-assisted dry-gel conversion (MW-DGC) combines advantages of concentrated reactants in DGC with fast heating by microwave irradiation. This novel combination allows to drastically decrease the amount of solvent needed for synthesis and reaction times with energy needed. Further, MW-DGC ...
