AMORPHOUS WATER

Annual Review of Physical Chemistry, 2004
▪ Abstract  After providing some background material to establish the interest content of this subject, we summarize the many different ways in which water can be prepared in the amorphous state, making clear that there seems to be more than one distinct amorphous state to be considered.

First-Order Amorphous-Amorphous Transformation in Silica

Physical Review Letters, 2000
Molecular simulations predict that a first-order amorphous-amorphous transformation occurs in SiO2 under pressure, analogous to the first-order amorphous-amorphous transformation known to occur in H2O. At low temperatures the first-order transformation is kinetically hindered, and an amorphous-amorphous transformation occurs instead by gradual spinodal

Amorphous Metallic Plastic

Physical Review Letters, 2005
We report cerium-based bulk metallic glasses with an exceptionally low glass transition temperature Tg, similar to or lower than that of many polymers. We demonstrate that, in near-boiling water, these materials can be repeatedly shaped, and can thus be regarded as metallic plastics.

Amorphous boron and amorphous-like borides

Journal of Non-Crystalline Solids, 1986
Investigations of the electrical and optical properties and thermal conductivity of a number of MB66 compounds have been carried out (M = Gd, Sm, Yb, Dy, Y). Their properties were compared with the properties of amorphous boron. Amorphous boron and MB66 compounds were shown to be materials-analogs due to the specific complex lattice of MB66 ...

Is simulated ‘‘amorphous’’ silica really amorphous?

AIP Conference Proceedings, 1994
We have carried out extensive molecular dynamics simulations for the pressure induced amorphization of quartz by means of a classical force‐field model. In agreement with earlier simulations, we find that a phase transition occurs within the experimental pressure range of the amorphization.

Pharmaceutical Amorphous Nanoparticles

Journal of Pharmaceutical Sciences, 2017
There has been a tremendous revolution in the field of nanotechnology, resulting in the advent of novel drug delivery systems known as nanomedicines for diagnosis and therapy. One of the applications is nanoparticulate drug delivery systems which are used to improve the solubility and oral bioavailability of poorly soluble compounds.

Amorphous Calcium Phosphate

2001
ACP is a unique calcium phosphate in that it lacks long-range crystalline order. Yet the constancy in the composition of ACP over a wide range of solution conditions suggests a well-defined local structural unit. Although this order within disorder is the most distinguishing feature of ACP, the solution instability of ACP and its ready transformation ...
