Zeolites are an important class of inorganic crystalline materials that have been widely used
in the fields of petroleum refining, petrochemical industry, and fine chemical industry, as …

Supercooled liquids and glasses are important for current and developing technologies.
Here we provide perspective on recent progress in this field. The interpretation of …

The field of phase transitions and critical phenomena continues to be active in research,
producing a steady stream of interesting and fruitful results. It has moved into a central place …

The physical properties of a topologically disordered amorphous material (glass), such as
heat capacity and thermal conductivity, are markedly different from those of its ordered …

We take familiar inorganic oxide glasses and non-oxide glasses and the liquids from which
they derive to review the current understanding of their atomic structure, ranging from the …

The vast majority of materials have a positive coefficient of thermal expansion and their
volume increases on heating. There has been considerable recent interest in materials …

We consider a system of coupled classical harmonic oscillators with spatially fluctuating
nearest-neighbor force constants on a simple cubic lattice. The model is solved both by …

We show that a vibrational instability of the spectrum of weakly interacting quasilocal
harmonic modes creates the maximum in the inelastic scattering intensity in glasses, the …

We poorly understand the properties of amorphous systems at small length scales, where a
continuous elastic description breaks down. This is apparent when one considers their …

High-conductivity oxide ion electrolytes are needed to reduce the operating temperature of
solid-oxide fuel cells. Oxide mobility in solids is associated with defects. Although anion …
