A team of researchers use in-situ transmission electron microscopy (TEM) to record the dynamic evolution of structural and electrical interfacial properties of zirconium dioxide films on aluminum oxide and indium gallium arsenide (InGaAs) substrates. This investigation paves the way towards faster, more efficient high-speed electronic devices.
Chunmeng Shi and co-workers from the Third Military Medical University in Chongqing, China, introduce a small-molecule-based cancer theranostic agent for simultaneous cancer-cell mitochondrial targeting, NIR imaging, and chemo-/PDT/PTT/multimodal therapeutic activities.
Researchers from the Suzhou Key Laboratory of Green Chemical Engineering, Soochow University, and from the State Key Laboratory of Molecular Engineering of Polymers, Fudan University, develop a one-step, solvent-free method to prepare a high-performance heterogeneous catalyst. The cobalt-based catalyst is highly dispersible in water and is effective for the tandem sodium borohydride dehydrogenation and nitrobenzene hydrogenation at room temperature.
Suzana P. Nunes, Klaus-Viktor Peinemann, and co-workers from the King Abdullah University of Science and Technology in Saudi Arabia describe a selective membrane with functionalized nanochannels formed by self-assembly of a hydrophobic block copolymer for nanofiltration applications.
Fengyu Li and Yanlin Song from the Chinese Academy of Sciences, along with their co-workers, have designed high-performance flexible perovskite solar cells (PSCs) for wearable electronics using green printing technology.
Researchers from Hong Kong Polytechnic University and the Hong Kong Polytechnic University Shenzhen Research Institute achieve remote and temporal tuning of luminescence intensity and wavelength in green- and blue-emissive piezophosphors by modulating the magnetic field. This novel method is promising for applications in magnetic optical sensing, piezophotonics, energy harvesting, nondestructive environmental surveillance, novel light sources, and displays.
University of Houston and Pennsylvania State University researchers fabricate conducting polymer microcups from polylactic-co-glycolic acid (PLGA) for neural applications and drug delivery. These microcups are tunable in terms of size, surface roughness, electrical properties, and drug release.
Researchers from Sun Yat-sen University, China, prepare a composite based on nickel nitride and sulfide nanosheets as the anode material for lithium ion batteries. The composite has enhanced cycle stability and lithiation capacity compared to the nitride and sulfide alone.
Ting Zhang and co-workers from the Suzhou Institute of Nano-Tech and Nano-Bionics at the Chinese Academy of Sciences develop a novel superhydrophobic and piezoresistive coating for wearable sensing devices. The coating is durable in harsh conditions and can be used to detect real-time human movement when fabricated as a wearable strain sensor.
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.
