Structural Transistions
in Glasses and Glassforming Liquids
Brillouin light scattering was used for the investigation
of glassforming systems of variable fragility, with the
objective to elucidate the glass transistion phenomenon.
A theoretical model was developed that provides consistent
description of the temperature dependence of real and imaginary
mechanical moduli of all the systems investigated. John Kiefferi
Ceramic Brake Rotor for Passenger Cars
Although currently too expensive for use in most passengers,
a new high-performance, lightweight, ceramic disc brake
has been developed. V. Kevorkijan
Dispersants for High-Alumina Castables
Zeta-potential data alone is not an appropriate parameter
to select dispersants for Al2O3-based
zero-cement castables and suspension when high solids loadings
are concerned. Salt-neutralized polyacrylic acid leads to
suspensions with superior viscosity and yield stress when
compared with those dispersed with citric acid. A.R. Studart and V.C. Pandolfelli
Alumina Ceramics for Ballistic
Protection, Part 2
High-alumina and alumina-zirconia ceramics have been
successfully used as armor material for personnel and vehicular
ballistic protection.. Eugene Medvedovski
