Sol Gel Method Performed for Biomedical Products Implementation

Mini-Reviews in Medicinal Chemistry, 2010
Sol-gel technology is an impressive and instructive innovation in science that necessitates a multidisciplinary approach for its important applications in the practice. An important peculiarity of the sol gel technology is the possibility to control the mechanism and kinetics of the chemical reactions, thus monitoring the final structure (particle size,

SUPERCONDUCTIVE CERAMICS OBTAINED WITH SOL–GEL METHODS

International Journal of Modern Physics B, 1988
Several sol–gel routes have been considered, studied and developed to produce large quantities of granulates which can be processed to obtain ceramics having good superconducting characteristics. In the considered process a mixture of commercial nitrates is atomized, at room temperature, in a solution 1:1 of Primene JMT and benzene, and a pale blue ...

Ferroelectric coatings by the sol-gel method

SPIE Proceedings, 1990
Recent research on ferroelectric films via the sol-gel method is discussed, with emphases on preparative problems, electrical and optical properties, and applications in devices. Ferroelectric thin films, including LiNbO3, BaTiO3, KNbO3, Pb(ZrTii)O3, and (SrBai..)Nb2O6, were investigated.

Silk fabrics modification by sol–gel method

Textile Research Journal, 2016
Sol–gel is a very effective method to obtain high purity ceramic and hybrid coatings on a variety of substrates. Thanks to their unique structure and extremely reduced thicknesses, sol–gel coatings can remain adherent and transparent even on flexible substrates such as textiles.

Hydrophobic Ceramic Surface by Sol-Gel Method

Advanced Materials Research, 2010
The sol-gel method was chosen in the experiment to make nano-structured coatings on the ceramics. In this experiment the TEOS, ETOH were chosen as the main reagents and the two group formulas whose scale were 3:50 and 18:25 were chosen to make the sol of silica by the way of sol-gel, and the two formula were mixed on some scale.

Fabrication of PZT BY sol-gel method

Proceedings of the 2010 Symposium on Piezoelectricity, Acoustic Waves and Device Applications, 2010
The sol-gel method was used to prepare the high purity lead zirconate titanate Pb(Zr,Ti)O 3 (PZT) piezoelectric ceramic powders. To determine the optimum fabrication process, the influence of calcined conditions and sintering conditions on the characteristics of PZT bulk was studied. After calcined at 900°C for 4hr, and then sintered at 1100°C for 2hr,

Ceramic superconductors synthesized by sol-gel methods

Physica C: Superconductivity, 1991
A sol-gel method is described based on the use of organic complexing agents in liquid solution, such as citric acid, ethylene-diamine-tetra-acetic acid (EDTA) and others. It is shown how the procedures can be designed on a scientific basis, using pM′-pH diagrams for the respective cation and complexing agent.

Electrode modification by the sol-gel method

The Journal of Physical Chemistry, 1993
Silica gel films prepared by the sol-gel route were used to modify platinum and transparent indium oxide electrodes. The silicon dioxide layer reduces electron transfer to the electrode but, due to the porous structure of the silica gel, does not completely prevent it. The tris(2,2'-bipyridyl)ruthenium(II) cation is incorporatcd into the gel layer, and

Sol-Gel Method in Oxide Material Technology

Glass and Ceramics, 2003
The principles of producing highly disperse powders of oxide materials, including complex compositions, using the sol-gel method are considered. Various compounds (polyacrylic acid, polyacrylamide, polyvinyl alcohol) are used as the gel-forming agents in true and colloid solutions.

Thin Coatings By The Sol-Gel Method

SPIE Proceedings, 1989
Thin oxide coatings may be prepared from solutions of alkoxides by the sol-gel method. The procedure consists in the application of a thin liquid layer of solution to the substrate and in the subsequent gelation of this coating, which, upon drying and heating, transforms into a glass or a ceramic.
