In the framework of the thermodynamics of irreversible processes and using a graphical approach based on the simple theorems of differential geometry, a generic phenomenological treatment of the glass transition is developed. A thermodynamic derivati

Boron Oxide plays a key role in numerous glasses of high technological importance, yet its role in glass structure is far from clear. Indeed, in recent years there have been serious chal lenges to previous structure concepts for both crystalline an

Comparisons were made for the structures of condensates from the ternary tetramethoxysilane (TMOS)/methyltrimethoxysilane (MTMS)/diethoxydimethylsilane (DEDMS) system and the binary MTMS/DEDMS system upon hydrolysis/polycondensation using infrared sp

Structural changes occurring during the heat treatment of gels that were prepared from binary tetramethoxysilane (TMOS)/diethoxydimethylsilane (DEDMS) mixtures were investigated using infrared spectra. Analysis of the spectral data indicated that the

The classical description of a melt cooling to form a solid glass is expressed by the volume-temperature behavior shown in Fig. 1. The point where a change of slope takes place in this graph is defined as the glass transition temperature, Tg. Its exa
