Low-temperature Sol-gel Approach for Creating New Functional Nanomaterials

摘要

It is well-known that production of a crystal matrix is as a rule accompanied by using hightemperatureudprocessing which considerably limits the area of applied use of the objects. In the presentudwork, we consider new approaches aimed at formation of crystalline highly active oxide phases without usingudannealing stage by achieving deep intercomponent penetration of disperse particles at the nanoleveludduring the sol-gel process reactions. The use of these approaches was possible in a single stage for the firstudtime: 1) entrapment of various biological objects in a ceramic biocompatible matrix necessary for obtainingudvaccines of new generation; 2) doping a crystal lattice up to 10at. % usingsoft chemistry method; 3) chemicaludmodification of biopolymers for the purpose of developing high-level operational characteristics. In thisudwork, trends in forming crystals from solutions for existing ceramic matrices are analyzed for the firstudtime. The main objects of study are materials of modified titania and alumina.When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/35209
