Heat Energy Leaps Through Empty Space, Thanks to Quantum Weirdness
If you use a vacuum-insulated thermos to help keep your coffee hot, you may know it’s a good insulator because heat energy has a hard time moving through empty space. Vibrations of atoms or molecules, which carry thermal energy, simply can’t travel if there are no atoms or molecules around. But a new study by…
Read MoreGoing to extremes
New research by Berkeley engineers may soon make it more practical to use battery-powered vehicles and devices in extreme temperatures, such as icy-cold winters in Minnesota or stifling-hot summers in Death Valley. Led by Chris Dames, professor of mechanical engineering, the researchers developed a thermal regulator that can improve the performance of lithium-ion batteries outside of what’s…

New research by Berkeley engineers may soon make it more practical to use battery-powered vehicles and devices in extreme temperatures, such as in icy-cold winters in Minnesota or stifling-hot summers in Death Valley. Those conditions represent temperature ranges that fall outside the narrow window — typically 20 to 40 degrees Celsius — needed for a…

Researchers in the Laser Thermal Laboratory have developed a new method for the stable doping of atomically layered transition-metal dichalchogenide materials TMDCs. TMDCs play a crucial role in next generation opto- electronic devices enabling new functionalities to overcome limitations of current semiconductor devices. Doping is a central issue in the integration of these new materials…

Dr. Hojeong Jeon and doctoral student Sangmo Koo of the Laser Thermal Laboratory LTL reported their work on the functionalization of the surface of biological devices by ablative direct laser writing in the August 20 issue of Nature Materials. Patterned surfaces with nanoscale craters can control the cell ability to stick to surfaces. This in…
