Supercritical fluids once thought uniform found to contain liquid clusters

Researchers at Pohang University of Science & Technology experimentally demonstrated the existence of nanometer-sized liquid clusters in supercritical fluids, overturning the prevailing notion of a single phase. These clusters persisted for up to an hour and have significant implications for industrial processes and natural environments.

Urban heat -- not a myth, and worst where it's wet

A new study reveals that urbanization reduces convection efficiency by 58 percent in wetter climates, leading to a significant rise in daytime temperatures. This finding challenges the long-held belief that vegetation loss is the primary cause of the urban heat island effect.

International team of physicists makes discovery about temperature in convection

An international team of physicists has made a groundbreaking discovery about the temperature profile in convection, which occurs in boiling liquids and turbulent movement of the Earth's outer core. The findings echo an important discovery from 1930 by Theodore von Kármán and Ludwig Prandtl, known as the Law of the Wall.
