Convection as a research area investigates buoyancy-driven and forced fluid motion arising from temperature or composition gradients, focusing on the coupled transport of momentum, heat, and mass in gases, liquids, and multiphase systems. It encompasses theoretical, numerical, and experimental studies of stability, transition to turbulence, pattern formation, and scaling laws in configurations such as Rayleigh–Bénard, thermal plumes, and mixed convection in boundary layers and porous media. This field underpins advances in geophysics, astrophysics, atmospheric and oceanic sciences, and engineering systems, where accurately resolving convective processes is essential for predictive modeling, control, and optimization of transport phenomena.
Covalent bonding is a widely understood phenomenon that joins the atoms of a molecule by a shared electron pair. But in nature, patterns of molecules can also be connected through weaker, more dynamic forces that give rise ...

Researchers at MIT recently published the first results of an experiment aimed at searching for axion dark matter by probing the axion-induced birefringence of electromagnetic waves. While these findings, published in Physical ...
Topological insulators raise the exciting hope of realizing lossless energy transport, which is true at ultralow temperatures. However, topological insulators fail to maintain this lossless 'magic' at room temperature.
