Oxides, inorganic materials

A significant recent advance has been the development of microfiltration and ultrafiltration membranes composed of inorganic oxide materials. These are presently produced by two main techniques (a) deposition of colloidal metal oxide on to a supporting material such as carbon, and (b) as purely ceramic materials by high temperature sintering of spray-dried oxide microspheres. Other innovative production techniques lead to the... 

Traditionally heterogeneous catalysts have been based primarily on inorganic oxide materials, and attempts to construct molecularly well-defined metal complex centres have been fewer in number. In contrast the much less used polymer-based heterogeneous catalysts have focussed more on immobilising well-defined catalytic entities. Interestingly these two areas are now moving closer towards each other, such that a healthy overlap has started to develop. This trend seems set to continue and can only benefit the whole heterogeneous catalysis field. 

He has carried out researches in various fields of inorganic chemistry (coordination chemistry of 3d-metals, high-temperature chemistry of molten fluorides), physical chemistry (phase equilibria in molten salt systems), electrochemistry (thermodynamics of metal-electrolyte interface, electrodeposition of refractory and other metals from molten salts, lithium batteries and active materials for them) and, more recently, nanochemistry of inorganic oxide materials. 

Principally there are two classes of materials which can be used as a sol-gel electrolyte The first one is based on the fabrication of an inorganic oxide material (e.g., Ta20s, Nb20s) and the other on the preparation of organic-inorganic hybrids which combine the better conductive properties of polymer type material with the better mechanical strength of inorganic material.

Electrospinning is a simple but extremely versatile method for obtaining continuous nano- and microfibers of natural and synthetic polymers, as well as of inorganic oxide materials. The process itself has been discussed in the first two chapters. Additional information for the interested reader can be found in reviews on the topic.
