Raman spectra of alkali and alkaline-earth borate glasses are reported. These spectra are
used to discuss the molecular structure of the glasses. The influence of additions of Al 2 O 3 …

This result has been applied to many liquids ranging from fused silica to liquid argon and
including polyatomic van der Waals as well as hydrogen-bonded liquids. Consistent fits to …

In evaluating the results of measurements of the viscoelastic behaviour of liquids and
polymers derived from cyclic shearing stress we usually employ reduced variables in which …

Extensive and accurate viscosity values for molten B2O3 are reported over the continuous
range from 20 poises (at 1400° C) to 1010 poises (at 318° C). The measurements were …

Molecular acoustics is the study of molecules and their interactions by means of ultrasonic
shear or longitudinal waves. When a shear wave propagates through a medium, there is no …

Early in 1975, Norbert Kreidl approached me for my opinion on the topic and novel format
which he was considering for the Fifth 11 Rollall Ceramic Materials Conference.* The theme …

Role of Free Volume in the Pressure Dependence of the Viscosity of Liquids Page 1 THE
JOURNAL OF CHEMICAL PHYSICS VOLUME 44, NUMBER 2 15 JANUARY 1966 Role of …

Although certain liquids show Arrhenius viscosity behavior over the whole liquid range, most
liquids have a substantial non-Arrhenius range in which their viscosity is described by the …

Infrared spectra, thermal expansion, viscosity, and other physical properties in the melt
system diopside-anorthite were measured in air at 1 atmosphere. The constituent silicate …

We suggest a model, according to which the local low activation stretching of a valence
bond network is a necessary condition for the realization of an elementary act of viscous flow …
