The collaborative effort of researchers from Skoltech, SB RAS Nikolaev Institute of Inorganic Chemistry, and RAS Institute for Problems of Chemical Physics translated into the development of advanced lead-free semiconductors for solar cells, based on complex antimony and bismuth halides. The results of their study were published in the Journal of Materials Chemistry A and showcased on the journal's cover page.
Underwater vehicles, diving robots, and detectors require their own energy supply to operate for long periods independent of ships. A new, inexpensive system for the direct electrochemical extraction of energy from seawater offers the advantage of also being able to handle short spikes in power demand, while maintaining longer term steady power. To do so, the system can autonomously switch between two modes of operation, as researchers report in the journal Angewandte Chemie.
Solar cells made of perovskite hold much promise for the future of solar energy. However, the material degrades quickly, severely limiting its efficiency and stability over time. Researchers from Eindhoven University of Technology, energy research institute DIFFER, Peking University and University of Twente have discovered that adding a small amount of fluoride to the perovskite leaves a protective layer, increasing stability of the materials and the solar cells significantly.
Research funded in part by the US Army identified properties in materials that could one day lead to applications such as more powerful data storage devices that continue to hold information even after a device has been powered off.
In the latest issue of the journal Nature, Army researchers and the University of Maryland demonstrate a transformative step in battery technology with the identification of a new cathode chemistry.
The smallest pixels yet created -- a million times smaller than those in smartphones, made by trapping particles of light under tiny rocks of gold -- could be used for new types of large-scale flexible displays, big enough to cover entire buildings.
Solar cells and photocathodes made of copper oxide might in theory attain high efficiencies for solar energy conversion. In practice, however, large losses occur. Now a team at the HZB has been able to use a sophisticated femtosecond laser experiment to determine where these losses take place: not so much at the interfaces, but instead far more in the interior of the crystalline material. These results provide indications on how to improve copper oxide and other metal oxides for applications as energy materials.
Northwestern University researchers have found that the enzyme responsible for the methane-methanol conversion in methanotrophic bacteria catalyzes the reaction at a site that contains just one copper ion. This finding could lead to newly designed, human-made catalysts that can convert methane -- a highly potent greenhouse gas -- to readily usable methanol with the same effortless mechanism.
Tiny light-emitting microalgae, found in the ocean, could hold the secret to the next generation of organic solar cells, according to new research carried out at the universities of Birmingham and Utrecht.
Close genetic analysis of 480 blue mallee eucalyptus plants provides clues to modify cultivars for greater yield, whether for essential oils or jet fuel.
