He has advanced these since leaving the chair. For example, a product of these advances is presently undergoing tests for industrial application, apart from considering the extension of formation of zeolites, beyond linking the Columns Three and Four elements, to other contiguous elements, to produce novel advanced materials, for industrial and domestic uses.
