Copper ions flow like liquid through crystalline structures

11/10/2018

Materials scientists have sussed out the physical phenomenon underlying the promising electrical properties of a class of materials called superionic crystals through the investigation of CuCrSe2. A better understanding of such materials could lead to safer and more efficient rechargeable batteries than the current standard-bearer of lithium ion.

Approach paves way for new antimicrobial materials

11/10/2018

Researchers have successfully incorporated 'photosensitizers' into a range of polymers, giving those materials the ability to render bacteria and viruses inactive using only ambient oxygen and visible-wavelength light.

Study opens route to flexible electronics made from exotic materials

10/10/2018

Engineers have developed a technique to fabricate ultrathin semiconducting films made from a host of exotic materials other than silicon. To demonstrate, they fabricated flexible films made from gallium arsenide, gallium nitride, and lithium fluoride - materials that exhibit better performance than silicon but until now have been prohibitively expensive to produce in functional devices.

HZB researchers are used to boost the efficiency of silicon solar cells

10/10/2018

The efficiency of a solar cell is one of its most important parameters. It indicates what percentage of the solar energy radiated into the cell is converted into electrical energy. The theoretical limit for silicon solar cells is 29.3 percent due to physical material properties. In the journal Materials Horizons, researchers describe how this limit can be abolished.

New fuel cell concept brings biological design to better electricity generation

09/10/2018

Fuel cells have long been viewed as a promising power source. But most fuel cells are too expensive, inefficient, or both. In a new approach, inspired by biology, a University of Wisconsin-Madison team has designed a fuel cell using cheaper materials and an organic compound that shuttles electrons and protons.
