When a beam of neutrons is directed towards a sample, the neutrons can be scattered elastically (without energy change) or inelastically (with energy change) depending on the nature of the interaction ...

While on Earth we mostly encounter the hexagonal, crystalline ice (like ice cubes, glaciers, snow), there are at least 20 other known ice phases, many of which have merely been theorised to exist in ...

For the first time, scientists have observed one of these exotic phases: Plastic Ice VII. “Plastic phases are hybrid states ...

In neutron scattering experiments, instruments count the scattered neutrons as a function of wave vector Q, which depends on the scattering angle θ and wavelength λ. For elastic scattering – i.e., ...

In everyday life, we typically encounter water in one of three familiar states—solid, liquid or gas. But there are in fact ...

What is Small-Angle Neutron Scattering (SANS)? Small-Angle Neutron Scattering (SANS) is a powerful analytical technique used to characterize the structure and properties of materials at the nanoscale.

Water isn't just liquid, ice, or vapor — under extreme conditions, it can transform into exotic phases, such as the newly observed plastic ice VII. This hybrid phase, predicted years ago but only ...

In everyday life, we typically encounter water in one of three familiar states – solid, liquid or gas. But there are in fact many more phases, some of which – predicted to exist at high temperature ...
