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.
Southwest Research Institute (SwRI) is expanding its heat exchanger testing capabilities to include megawatt-scale performance evaluations. This move addresses a significant market gap for high-heat transfer rates involving high-temperature and -flowrate applications in data centers, defense, and other fields.
Tina Rost will use a $800,000 NSF CAREER award to control the disorder in high-entropy ceramics, making them stronger and more heat-resistant. Her team aims to develop new materials with tailored electrical, magnetic, and mechanical properties using machine learning-enhanced analysis.
A research team at CityU developed a multifunctional composite polymer coating with both radiative and non-radiative cooling capacity, enhancing heat dissipation in wearable electronics. The cooling interface achieved temperature drops of over 56°C, improving the performance of skin electronic devices.
Researchers developed kirigami-processed cellulose nanofiber films that dramatically improve cooling functionality, reducing thermal resistance by about one-fifth. These films can be used to create new cooling devices for wearable electronics, addressing bulkiness and inflexibility issues.
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.
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.
Scientists propose that a massive thermal burp could have briefly insulated the moon's core, allowing it to cool quickly and produce a magnetic field. This theory also explains the uneven distribution of metal-rich volcanic rock on the moon's surface.
