Liquid sulfur changes shape and goes critical under pressure

Scientists from the ESRF, together with teams from CEA and CNRS/Sorbonne Université, have found the proof for a liquid-to-liquid transition in sulfur and of a new kind of critical point ending this transition. Their work ...

Order out of disorder in ice

The glass structure of a material is often believed to mimic its corresponding liquid. Polyamorphism between ices has been used as a guide to elucidate the properties of liquid water. But how many forms of amorphous ices ...

Observing changes in the chirality of molecules in real time

Some molecules can exist in two mirror-image forms, similar to our hands. Although such so-called enantiomers have almost identical physical properties, they are not the same. The fact that they behave to each other like ...

Improved catalytic processes for the synthesis of phenol

Researchers at the University of Electro-communications, Tokyo report a single-site catalytic platform with high selectivity for the single-step synthesis of phenol in a paper appeared in ACS catalysis.

Theories describe dynamically disordered solid materials

Theoretical physicists at Linköping University have developed a computational method to calculate the transition from one phase to another in dynamically disordered solid materials. This is a class of materials that can ...

Physicists made crystal lattice from polaritons

An international research team produced an analog of a solid-body crystal lattice from polaritons, hybrid photon-electron quasiparticles. In the resulting polariton lattice, the energy of certain particles does not depend ...

Acoustic emissions from organic martensite analogues

Some organic crystals jump around when heated up. This happens because of an extremely fast change in their crystal structure. In the journal Angewandte Chemie, scientists have now demonstrated that the crystals send out ...
