Thio Sol-Gel Approach to An Octanuclear Titanium(IV) Cluster Compound

Introduction to Sol-Gel

A zipper model approach to the thermoreversible gel-sol transition

2014 The gel-sol transition of thermo-reversible gels is examined theoretically by using a zipper model which has been used for explaining the helix-coil transition and the melting of deoxyribonucleic acid (DNA). The endothermic peaks in a heating curve of differential scanning calorimetry for various thermoreversible gels are analysed by this treatment. J. Phys. France 51 (1990) 1759-1768 15 A...

Synthesis and characterization of an octanuclear copper(I) methanediide cluster.

The reaction of [K{CH((i)Pr2P=S)2(C9H6N-2)}]n (1) with one equivalent of CuCl in THF afforded a rare octanuclear copper(I) methanediide cluster (3). The structure of compound 3 as determined by X-ray crystallography was found to have eight copper atoms that form a Gyrobifastigium (J26).

the sol–gel technique

The sol–gel technique is a highly flexible technique for fabrication of oxide glasses, and various researchers have previously reported fluorescence studies of Er-doped sol–gel films and monoliths. Here we report the fabrication of Er-doped strip-loaded sol–gel silicate waveguides, using a silica–titania–alumina host composition, and Er concentrations up to f1.1=10 Er rcm, for possible applicat...

Two Simple Approaches to Sol-Gel Transition

We represent a theory of polymer gelation as an analogue of liquid-glass transition in which elastic fields of stress and strain shear components appear spontaneously as a consequence of the cross-linking of macromolecules. This circumstance is explained on the basis of obvious combinatoric arguments as well as a synergetic Lorenz system, where the strain acts as an order parameter, a conjugate...
