“#New fabrication method brings single-crystal perovskite devices closer to viability” A single-crystalline perovskite thin film during the transfer process. Credit: Yusheng Lei Nanoengineers at UC San Diego developed a new method to fabricate perovskites as single-crystal thin films, which are more efficient for use in solar cells and optical devices than the current state-of-the-art polycrystalline…
“#Electrochemical doping: Researchers improve carbon nanotube transparent conductors” An outline of the experiment. Credit: Pavel Odinev / Skoltech Skoltech researchers and their colleagues from Aalto University have discovered that electrochemical doping with ionic liquid can significantly enhance the optical and electrical properties of transparent conductors made of single-walled carbon nanotube films. The results were published…
“#Redesigning lithium-ion battery anodes for better performance” Argonne scientists observed reversible volume and phase change of micrometer-sized phosphorus particles during charge and discharge. Credit: Argonne National Laboratory / Guiliang Xu Scientists at Argonne National Laboratory have made progress toward a higher-capacity lithium-ion battery to meet rising consumer demand. With the growing number of electric vehicles…
“#Research on metallic nanoparticles may lead to improved solar cells” The feasibility of collecting the charges in a semiconductor means that they can be used in solar cells and in artificial photosynthesis. Credit: Matton In a new study, a research group at Uppsala University explain their outstanding success in harvesting “hot electron holes.” The results…
“#Mapping crystal shapes could fast-track 2-D materials” Inspired by the work of Japanese snowflake researcher Ukichiro Nakaya, materials scientists from Rice University the University of Pennsylvania created a Nakaya-like diagram of 2D crystal shapes of molybdenum disulfide produced via chemical vapor deposition (left) and a complete morphology diagram of molybdenum sulfide (right).

“#Taking the guesswork out of twistronics” Atomic scale moiré pattern created by overlapping two skewed sheets of graphene. Credit: Wikicommons The twist has been taking the field of condensed matter physics by storm. No, not the 1960s dance craze made famous by Chubby Checker— the stunning discovery that two sheets of graphene, a flat honeycomb-shaped lattice of carbon,…
“#Discovery of disordered nanolayers in intermetallic alloys” HAADF-STEM image reveals the ultrathin disordered layer at the grain boundaries with a thickness of about 5nm. Credit: Science DOI: 10.1126/science.abb6830 Intermetallic alloys potentially have high strength in a high-temperature environment. But they generally suffer poor ductility at ambient and low temperatures, hence limiting their applications in aerospace…
