Page 14: Research news on Phase transitions

Phase transitions as a research area investigates qualitative changes in the macroscopic state of matter or systems as control parameters such as temperature, pressure, or external fields are varied, with emphasis on critical phenomena, universality, and order-parameter behavior. It encompasses equilibrium and nonequilibrium transitions, including first- and second-order transitions, symmetry breaking, renormalization-group theory, and scaling laws. The field spans condensed matter physics, statistical mechanics, and interdisciplinary complex systems, using analytical, numerical, and experimental methods to characterize phase diagrams, critical exponents, collective excitations, and emergent structures, and to understand how microscopic interactions give rise to distinct thermodynamic or dynamical phases.

Nano droplets go skiing at high temperatures

Currently, many (nano)structures are grown in layers, one above the other, but their ordering on the atomic scale is generally far from perfect. Researchers from the University of Twente have aimed for a better understanding ...

Stabilizing precipitate growth at grain boundaries in alloys

Materials are often considered to be one phase, but many engineering materials contain two or more phases, improving their properties and performance. These two-phase materials have inclusions, called precipitates, embedded ...

Discovery of ferroelectricity in an elementary substance

National University of Singapore (NUS) physicists have discovered a novel form of ferroelectricity in a single-element bismuth monolayer that can produce regular and reversible dipole moments for future applications of non-volatile ...

New phases of water detected

Scientists at the University of Cambridge have discovered that water in a one-molecule layer acts like neither a liquid nor a solid, and that it becomes highly conductive at high pressures.
