Waste Oil to Wonder Material: Transforming Trash Into Supercapacitor Gold | Newswise

David Bale5 months ago06 mins

Newswise — Amid an escalating global energy crisis, the need for high-performance energy storage solutions is more pressing than ever. Supercapacitors, known for their fast charge/discharge rates and longer cycle life compared to traditional batteries, have emerged as a critical component in future energy systems. However, to meet growing demand, supercapacitors require high-quality electrode materials…

Breakthroughs in Thermal Photonics Enable Efficient Subambient Daytime Radiative Cooling for Vertical Surfaces | Newswise

David Bale5 months ago06 mins

Newswise — Radiative heat transfer is one of the most critical energy transfer mechanisms in nature. However, traditional blackbody radiation, due to its inherent characteristics such as non-directional, incoherent, broad-spectrum, and unpolarized nature, results in energy exchange between the radiating body and all surrounding objects, significantly limiting heat transfer efficiency and thermal flow control. These…
