A Fluorescent Rotaxane: Molecular Shuttle and Sensor Gel
The fluorescent rotaxane is a molecular shuttle sensitive to temperature, pH, and solvent polarity changes. It forms a gel which changes its fluorescence properties upon acidic/basic gas exposure and can be turned into a liquid by shaking, heating, and by adding anions.
Learning from the cactus: Artificial water-collecting spines
Artificial cactus spines, which can collect fog from the air, have been constructed by a research group from Beihang University. This water-harvesting method is of great interest in a world where water is becoming more scarce.
Custom Fit: Self-Wrapping 3D Electronics
A team of researchers at Stanford University has developed shape-controlled, self-wrapping electronics based on carbon nanotubes.
Facile, Green, and Tunable: Synthesizing Catalytically Active Multimetallic Mesoporous Spheres
A facile, green, and tunable synthesis for mesoporous spheres consisting of noble metals is developed. The spheres are potential catalysts in fuel cells.
Color-controlled perovskite quantum dots
New research published in Advanced Science by a team of Chinese researchers presents the control of the emission color of CH3NH3PbBr3 perovskite quantum dots using precipitation temperature.
Heatproof roof can cool your house for free
Researchers at the University of Technology in Sydney have developed a new material that can keep roofs cooler than the air above them, even in direct sunlight.
Hybrid Superstructures Boost Lithium-Ion Research
Hierarchical structuring in hybrid amorphous/crystalline nanowire bundles provides a promising anode material for lithium-ion batteries.
Spacer Layers Enhance Organic Photovoltaic Performance
Inserting a spacer layer between the donor and the acceptor material of organic photovoltaic (OPV) devices enhances their power conversion efficiency.
In Situ Studies Pave Path for Stable Lithium Electrodes
Perpendicular inhomogeneities in lithium electrodes have been studied in real time using synchrotron radiation.
