University of Illinois researchers have developed a theory that explains how glassy materials behave and predict the speed of molecular motion changes with temperature. The theory, based on thermodynamic measurements of heat capacity, provides a universal form for expressing glass transition phenomena.
Scientists at PPPL have achieved a significant breakthrough in fusion research, producing the highest plasma current ever recorded in a spherical torus device - 1 million amperes. This milestone is crucial for understanding the physics of fusion and potentially leading to more efficient development paths for fusion energy.
Two scientists suggest that satellites' waste heat could be causing distant spacecraft to slow down faster than expected. The heat is emitted in a direction opposite to the Sun, giving the spacecraft a small push towards the Sun and slowing them down.
Urban Heat Island Pilot Project measures city cooling with urban forests. Cities like Sacramento & Salt Lake City use trees to reduce surface heating, improving air quality & mitigating heat stress. The study helps develop planning strategies for cities worldwide.
Researchers are studying the impact of Atlanta's growth on its air quality and temperatures over two decades. Trees have been found to reduce temperatures, with a difference of up to 31 degrees between paved areas and tree-lined spaces. The study aims to provide insights for cities reshaping themselves for comfort and lower heating bills.
The Oak Ridge National Laboratory has developed a new wall testing and rating procedure to determine the thermal performance of entire walls, rather than just insulation. This approach accounts for increased heat leakages in corners, doors, windows, and studs, providing more accurate measurements of building energy performance.
