Amorphous solid - Wikipedia, the free encyclopedia
An "amorphous solid" is a solid in which there is no long-range order of the positions of the atoms. (Solids in which there is long-range atomic order are called crystalline solids or morphous). Most ...

amorphous solid (physics), Atomic-scale structure, Britannica Online Encyclopedia, The absence of long-range order is the defining characteristic of the atomic arrangement in amorphous solids. ... Figure 2: The atomic arrangements in (A) a crystalline solid, (B) an amorphous solid, and (C) a gas. [

(Thus, the term amorphous, literally “without form or structure,” is actually a misnomer in the context of the standard expression amorphous solid.) The well-defined short-range order is a consequence of the chemical bonding between atoms, which is responsible for holding the solid together.

In this contribution, we report some general solid-state spin diffusion NMR methods, based on intramolecular and intermolecular spin diffusion, for the measurement and calculation of spin-diffusion coefficients in amorphous polymers and their blends using only NMR data.

Amorphous Solids; A solid substance with its atoms held apart at equilibrium spacing, but with no long-range periodicity in atom location in its structure is an amorphous solid. Examples of amorphous solids are glass and some types of plastic.

A concept of amorphous and microporous amorphous ice, developed in the early 1980s, is presented, but more recent ... Modern experimental and theoretical studies of ice particles have focused on the infrared spectra and structure of the ice surface, and the interaction of the surface with molecular adsorbates.

Structure and relaxation in amorphous materials studied by solid state NMR and computer simulations ... This thesis is aimed at investigating the structure and relaxation in amorphous materials using solid state NMR and computer simulations. Amorphous solids, unlike crystalline materials, lack long range order.
