An international multi-institution team of scientists has synthesized graphene nanoribbons -- ultrathin strips of carbon atoms -- on a titanium dioxide surface using an atomically precise method that removes a barrier for custom-designed carbon nanostructures required for quantum information sciences.
Treating silicon with carbon dioxide gas in plasma processing brings simplicity and control to a key step for making solar cells.
Rice University engineers make 2D materials for valleytronics, a platform for information processing and storage that relies on the manipulation of electrons' positions in energetic 'valleys.'
A University of Central Florida researcher is working to make portable devices and electric vehicles stay charged longer by extending the life of the rechargeable lithium-ion batteries powering them. He is doing this by making the batteries more efficient, with some of his latest work focusing on keeping the anode from falling apart over time. The new technique is detailed in the journal Advanced Materials.
A group of scientists from Korea has discovered that the amount of alkali metal introduced into crystals of flexible thin-film solar cells influences the path that charge carriers take to traverse between electrodes, thereby affecting the light-to-electricity conversion efficiency of the solar cell. Given the immense application potential that such solar cells have today, this finding could be key to ushering in a green future.
As part of an international collaboration, a team at the HZB has examined the corrosion processes of high-quality BiVO4 photoelectrodes using different state-of-the-art characterisation methods. The result is the first operando stability study of high-purity BiVO4 photoanodes during the photoelectrochemical oxygen evolution reaction (OER). This work shows how the stability of photoelectrodes and catalysts can be compared and enhanced in the future.
This is the first report for the syntheses of water-soluble polyimides which are Interestingly derived from bio-based resources, showing high transparency, tunable mechanical strength and the highest thermoresistance in water-soluble polymers reported ever.
A deeper understanding of efficiency-limiting processes provides design rules for organic solar cell materials.
Based on a quantum cascade laser (QCL) emitting mid-infrared light, the researchers developed a basic optical neuron system operating 10,000× faster than biological neurons. Their report is published in Advanced Photonics.
Researchers at National University of Science and Technology MISIS (NUST MISIS) have managed to develop a unique method to process bulk metallic glasses. According to the authors of the study, they have managed to find processing conditions that significantly improve the quality of this promising material. The research results were published in Journal of Alloys and Compounds.
