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 ...

Whereas structural and vibrational properties of crystalline materials can be measured in great detail by various techniques, properties of amorphous materials are much harder to resolve. For this and ...

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 ...

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 ...

Glassy states represent a fascinating class of disordered materials in which atoms or molecules are frozen into non-crystalline arrangements. Their vibrational properties differ markedly from those of ...

Researchers have developed a new method for understanding the structure organization of disordered materials fundamentally different from previous geometric approaches of ordered crystals. This ...

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 ...

Weighing the pros and cons of hot-melt extrusion and spray drying. The oral route remains the most preferred method for delivering drugs. It offers good patient compliance due to its acceptability, ...

Scientists from Tokyo Metropolitan University have created a new model for disordered materials to study how amorphous materials resist stress. They treated groups of atoms and molecules as squishy ...
