Researchers introduce a new device concept for electroluminescent displays, which does not require transparent electrodes and can be used as remotely readable, spatially-responsive sensors that emit light in response to the accumulation and distribution of materials on the device surface.
A new type of hybrid hydrogel for tissue regenerative therapy—Anisogel—is developed by Abdolrahman Omidinia-Anarkoli, Laura De Laporte, and co-workers from the Leibniz Institute for Interactive Materials in Aachen, Germany. This low-invasive hydrogel is promising for healing body tissues that consist of an aligned architecture, such as the heart, kidney, muscles, and nerves.
Lambert Alff and his team from Darmstadt University of Technology (TU Darmstadt) in Germany, along with their collaborators, propose a novel unified model for hafnium-oxide resistive random access memory (RRAM) based on the role of oxygen vacancy defects.
Thomas D. Anthopoulos and colleagues report a simple, environmentally-friendly processing method for copper(I) thiocyanate (CuSCN), a next-generation hole-transport layer (HTL) for organic and hybrid perovskite solar cells. The power conversion efficiency reaches 17.5%—a remarkable improvement over conventional polymer HTLs.
University of Waterloo researchers develop a bifunctional oxygen electrocatalyst based on graphene that can recharge zinc-air batteries more efficiently.
Jordi Matorell and co-workers achieve a longer lifetime of polymer solar cells by addressing the issue and mechanism of UV-induced “burn-in”, a phenomenon linked to rapid degradation of electron transport.
Highly efficient, red-emissive carbon quantum dots (R-CQDs) with a quantum yield of 53% are prepared and a CQD-phosphors-based warm white-light-emitting diode (WLED) is realized for the first time.
Researchers from Pohang University of Science and Technology and Pusan National University engineer a bioinspired blood vessel for treating ischemic diseases using a 3D bioprinting technique.
Chunrui Ma, Ming Liu, and colleagues develop a practical way to transfer flexible, centimeter-scale, single-crystalline spinel ferrite oxide thin films onto flexible substrates for applications in flexible and wearable electronics.
Researchers from the Indian Institute of Science Education and Research demonstrate a simple and effective approach for tuning the redox properties of perylene diimides as high-voltage cathodes for organic sodium-ion batteries.
