Scientists elucidate the crystal structure of sodium boride

An international team of scientists jointly with Professor Artem Oganov of Skoltech and the Moscow Institute of Physics and Technology report the chemical composition, crystal structure and properties of Na2B30 ‒ a compound ...

Is glass transition driven by thermodynamics?

Glassy substances are everywhere, yet this state of matter is not completely understood. The basic picture is clear enough—glasses are solids that lack the regular atomic structure of a crystal. How and why they form, however, ...

Solution to distortion effect in STM scanning

STM scanning experiments on poorly conducting materials are challenging, and can cause a distortion effect. A new model corrects for this effect, allowing physicists to better study materials in their quest to understand ...

New theory on liquid crystals with high symmetry

LCD screens use liquid crystals, which have a high degree of order, even though they form a fluid. A new theory detailed in Physical Review X maps out the interplay between order, temperature and symmetry.

New flowchart to eliminate universe models

Cosmologists have many possible models for the universe, of which only one can be true. A new flowchart detailed in Physical Review D on November 7 will eliminate some of them when two specific universe features are accurately ...
