Harnessing the Marangoni Effect in Semiconductor Manufacturing
Researchers from the University of Hong Kong report how solution shearing of organic semiconductor crystals is influenced by a surface tension gradient. Using a Marangoni-effect-assisted bar coating method, ultrathin, uniform layers of crystals with large domain sizes are obtained that show excellent performance in organic field-effect transistors.
Photoreduction of Gaseous Nitrogen to Ammonia using Layered Double Hydroxide Nanosheets
For the first time, a new class of metal-to-metal charge-transfer (MMCT) systems is facilely synthesized.
A Unified Model for Hafnium-Oxide-Based Resistive Random Access Memory
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.
Aqueous-Processed Hole-Transport Layer for High-Performance Solar Cells
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.
Remove Nuclear Waste With Smart Photonic Crystals
Photonic crystal hydrogels for monitoring and removal of uranium in water.
3D-Printed, Bioinspired Blood Vessels for Treatment of Ischemic Diseases
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.
