The future of sol-gel science and technology

Abstract

Abstract. This paper addresses the future prospects for sol-gel processing. It includes responses from nearly two dozen leading practitioners of the sol-gel art, who were kind enough to answer a questionnaire about the present state and future directions of the field, Overall, the prospects appear quite bright; but achievement of anything like the full potential of the method will require greatly increased interaction between sol-gel specialists and device technologists.

Dependence of zinc aluminate microscopic structure on its synthesis

“…This result is also consistent with that reported by Bonhomme-coury et al [9]. However, sec-butoxide species with a larger molecular structure would undergo slower hydrolysis, leading to gradual formation of alumina sol [3]. At a lower temperature (25 8C), ASB which was originally available in slurry form was incompletely dispersed in ethanol, resulting in the relatively lower stability of sol formation (& in Fig.…”

“…Among various composites, alumina doped with zinc oxide is recognized as one of the most promising nanomaterials due to their synergetic advantages, which are high stability, high mechanical strength and a relatively wide band-gap energy [1,2]. Consequently, there are many investigations of proposing methods for fabricating those nanocomposites, for instance, sol-gel, sputtering and hydrothermal techniques [3][4][5]. Among them, sol-gel is one of the most promising methods because it could produce homogeneous product with consistent quality at low synthesized temperature and low investment.…”

Effect of Centrifugal Speed on the Anticorrosive Properties of Bismuth-Silicon Coatings by Sol-Gel on 316l Substrates

“…Metals are part of the basic equipment of most of the industrial fabric, including very diverse segments such as the oil, chemical, automotive, construction, and health industries. However, the steels are susceptible to corrosion phenomena due to chemical or electrochemical reactions, with the consequent deterioration of their properties limiting their life in use and losing efficiency in the applications to which it is destined, leading to a technological, economic and of health 2,3,4 . Among the metals, it is important to apply the steels as the AISI 316L which is commonly used in food preparation equipment, especially in chloride environments; chemical processing, equipment; laboratory benches and equipment; rubber, plastics, pulp and paper machinery; pollution control equipment; boat fittings, value and pump trim; heat exchangers; pharmaceutical and textile industries and condensers, evaporators and tanks 5,6 .…”

The sol–gel approach as a method of synthesis of xMgO·ySiO2 powder with defined physicochemical properties including crystalline structure

“…In addition, the sol-gel method ensures the high purity of the products and the possibility of mixing organic and inorganic components on a nanometric scale. The process usually takes place at low temperature and in mild reaction conditions, which permits, for example, the trapping of molecules such as enzymes or proteins, which have low thermal and chemical stability [12].…”
