Ionocaloric refrigeration would eliminate the risk of greenhouse gases escaping into the atmosphere by replacing them with solid and liquid components. Image credit: Jenny Nuss / Berkeley Lab.

Ionocaloric Cooling: Novel Method of Refrigeration Developed

Jan 4, 2023 by News Staff

Solid- or liquid-state cooling strategies often rely on caloric effects in which materials are taken through some sort of phase change. Researchers from...

Kapil et al. describe the phase behavior of monolayer-confined water by calculating its pressure-temperature phase diagram: (a-g) the pressure-temperature phase diagram of monolayer water was calculated using an machine learning potential that delivers first-principles accuracy; the solid and dashed lines indicate first-order and continuous phase transitions, respectively; the gray regions indicate the statistical uncertainty for solid-solid phase transitions and, for the other transitions, the uncertainties arising from studying a finite number of thermodynamic states; the diagonally hatched area indicates the region in which square and flat-rhombic phases are near degenerate; diagrams of the hexagonal (a), pentagonal (b), square (c), flat-rhombic (d), hexatic (e), superionic (f) and liquid (g) phases are shown with oxygen atoms in red, hydrogen atoms in gray and hydrogen bonds shown by blue lines.

Monolayer-Confined Water Acts Like Neither Liquid Nor Solid, Scientists Say

Sep 14, 2022 by News Staff

Water in a one-molecule layer acts like neither a liquid nor a solid, and becomes highly conductive at high pressures, according to a new paper published...

Trachenko et al. show that a combination of two dimensionless fundamental constants results in a new dimensionless constant that provides the upper bound for the speed of sound in condensed phases. Image credit: Gerd Altmann.
