Internationalisation of sustainable hydrogen technology

Green hydrogen and fuel technology are a new focus of the Export Initiative Environmental Technologies (EXI). The University of Bayreuth has recently become involved in this funding programme of the…

Metasurface-based antenna turns ambient radio waves into electric power

Technology could make it possible to use radio emissions from cell phone networks to wirelessly power sensors and LEDs. Researchers have developed a new metasurface-based antenna that represents an important…

A potential breakthrough for production of superior battery technology

Micro supercapacitors could revolutionise the way we use batteries by increasing their lifespan and enabling extremely fast charging. Manufacturers of everything from smartphones to electric cars are therefore investing heavily…

“Workhorse” of photovoltaics combined with perovskite in tandem for the first time

Tandem cells made of silicon and perovskite are able to convert the broad energy spectrum of sunlight into electrical energy more efficiently than the respective single cells. Now, for the…

Combine AI and atomic-scale images in pursuit of better batteries

Today’s rechargeable batteries are a wonder, but far from perfect. Eventually, they all wear out, begetting expensive replacements and recycling. “But what if batteries were indestructible?” asks William Chueh, an…

World’s Smallest Battery Can Power Computer with the Size of a Grain of Dust

A research team led by Chemnitz University of Technology with the participation of IFW Dresden and Changchun Institute of Applied Chemistry present an application-oriented method for an unsolved problem in…
