(Nanowerk News) Many substances with different chemical and physical properties, from diamonds to graphite, are made up of carbon atoms. Amorphous forms of solid carbon do not have a fixed crystal ...

Anything made out of plastic or glass is known as an amorphous material. Unlike many materials that freeze into crystalline solids, the atoms and molecules in amorphous materials never stack together ...

Glassy state: a new field theory describes amorphous materials such as glass beads. (Courtesy: iStock/schmidt-z) Many common materials such as glass, compacted sand and toothpaste have a solid’s ...

Scientists at EPFL and AstraZeneca have developed a method to map the atomic-level structure of amorphous drugs, demonstrated on a GLP-1 receptor agonist candidate for diabetes and obesity treatment.

In a crystalline solid, the atoms form an ordered lattice. Crystalline solids respond elastically to small deformations: When the applied strain is removed, the macroscopic stress, as well as the ...

Material engineers and scientists have long wanted to understand the atomic structures of amorphous solids such as glass, rubber and plastics more fully. Unlike the structures of crystalline materials ...

Researchers explain the distinctive low-temperature thermal properties of glasses using molecular dynamics simulations. By focusing on string-like defects, they were able to create a unified ...

AZoNano speaks to Dr. John Miao about his involvement in the breakthrough research that could rewrite our understanding of how substances are formed at an atomic level. Using an innovative atomic ...

The low-frequency vibrational and low-temperature thermal properties of amorphous solids are markedly different from those of crystalline solids. This situation is counterintuitive because all solid ...

For more than a century, an important class of matter -- the amorphous solid -- has eluded scientists' ability to depict nature at the level of atoms and molecules. Until now. A new study reports the ...

This is a preview. Log in through your library . Abstract Mechanical deformation of amorphous solids can be described as consisting of an elastic part in which the stress increases linearly with ...
