Scientists discover how oxygen loss saps a lithium-ion battery’s voltage

Measuring the process in unprecedented detail gives them clues to how to minimize the problem and protect battery performance. When lithium ions flow in and out of a battery electrode…

Easy detection of materials

A team at Landshut University of Applied Sciences has developed a low-cost, mobile near-infra-red spectrometer which provides information about different substances; the goal is its further development up to and…

Insulators: Safe under Maximum Load

Insulator strings connect the live conductor to overhead-line towers. Researchers at TU Graz simulated for the first time when and under what conditions different loads act on these strings. Overhead…

Intelligent electronic microsystems from green material

A research team from the University of Massachusetts Amherst has created an electronic microsystem that can intelligently respond to information inputs without any external energy input, much like a self-autonomous…

Saving the climate with solar fuel

Produced in a sustainable way, synthetic fuels contribute to switching mobility to renewable energy and to achieving the climate goals in road traffic. In the mobility demonstrator “move” Empa researchers…

Lead Halide Perovskites – a Horse of a Different Color

In a joint experimental and theoretical effort between Lund University (Sweden), the Russian Academy of Science (Russia), and the Center for Advancing Electronics Dresden at Technische Universität Dresden (Germany), researchers…

Stepstone for sustainable batteries – greener carbons

Lithium-ion batteries require in addition to lithium metal a number of sophisticated functional materials for their performance. Some of them sound rather unspectacular: conductive additives. In fact, conductive additives like…

Supplying rural areas with electricity sustainably

Interactive design tool from Fraunhofer for innovative energy infrastructures. Germany is supposed to become climate-neutral by 2045. The federal govern-ment’s new climate protection law stipulates this. Greenhouse gas emissions are…

Light-shrinking material lets ordinary microscope see in super resolution

Electrical engineers at the University of California San Diego developed a technology that improves the resolution of an ordinary light microscope so that it can be used to directly observe…

New Description of Electrification by Contact: Transfer of Charge Observed

Everyone has gotten an electric shock when touching a door handle. That’s because when two different substances touch, an electrostatic charge can occur that dissipates with a small flash. This…
