Coating helps electronics stay cool by sweating

Mammals sweat to regulate body temperature, and researchers from Shanghai Jiao Tong University in China are exploring whether our phones could do the same. In a study published January 22 in the journal Joule, the authors ...

Porous polymer coatings dynamically control light and heat

Buildings devote more than 30% of their energy use to heating, cooling, and lighting systems. Passive designs such as cool roof paints have gone a long way toward reducing this usage, and its impact on the environment and ...

Would a carbon tax help to innovate more-efficient energy use?

Taxing carbon emissions would drive innovation and lead to improved energy efficiency, according to a new paper published in Joule from Carnegie's Rong Wang (now at Fudan University), Harry Saunders, and Ken Caldeira, along ...

New coating brings lithium metal battery closer to reality

Hope has been restored for the rechargeable lithium metal battery—a potential battery powerhouse relegated for decades to the laboratory by its short life expectancy and occasional fiery demise while its rechargeable sibling, ...

Ammonia for fuel cells

Fuel cells are pollution-free power sources that convert chemical energy to electricity with high efficiency and zero emissions. Fuel cell cars, trucks, and buses would allow people to travel long distances with convenient ...

Mapping the energetic landscape of solar cells

A new spectroscopic method now makes it possible to measure and visualize the energetic landscape inside solar cells based on organic materials. It was developed by a research team led by Prof. Dr. Yana Vaynzof, a physicist ...
