11/10/2018Materials 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.
11/10/2018Researchers 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.
10/10/2018Engineers 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.
10/10/2018The 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.
09/10/2018A research group from Chalmers University of Technology, Sweden, has made great, rapid strides towards the development of a specially designed molecule which can store solar energy for later use. These advances have been presented in four scientific articles this year, with the most recent being published in the highly ranked journal Energy & Environmental Science
09/10/2018Fuel 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.
08/10/2018Researchers are documenting the different temperature and proton dosages required to make defects that will further allow silicon carbide to be used for quantum technology.
08/10/2018Scientists from the University of Liverpool, University College London and East China University of Science and Technology have synthesized a new organic material that can convert water into hydrogen fuel using sunlight.
05/10/2018A new material that is as stiff as metal but flexible enough to withstand strong vibrations could transform the car manufacturing industry, say experts from the University of Surrey.
05/10/2018A Florida State University research team has discovered that a unique organic-inorganic compound containing zero-dimensional molecular clusters emits a highly efficient blue light.
