Facet-controlled synthesis strategies for Cu2O-based nanocrystals are reviewed and properties that make them suitable for numerous applications in sensing and catalysis are highlighted.
Highly Detective Photodetector Based on Graphene-Silicon Heterojunction
Researchers devise a highly detective photodetector based on graphene-silicon heterojunctions with interface improvement by introducing a thin interfacial oxide layer.
Mimicking human skin with haptic pressure sensors
Chen et al. have developed haptic memory arrays which can detect and retain external pressure distribution.
Modeling, Design and Development of Soft Pneumatic Actuators
This work presents a design tool for soft pneumatic actuators using finite element method adaptable to a range of soft materials and design parameters.
Quantum Cascade Lasers
Steady progress turns multi-wavelength quantum cascade laser arrays into a powerful versatile source for next-generation spectroscopy and stand-off detection systems.
Don't touch: Operating displays with moisture
A new sensor technology could enable touchless displays that respond to moisture emitted by the human body.
A Flexible and Sensitive miRNA Biosensor
Low concentrations (10 × 10−15 M) of the disease biomarker microRNA-21 (miRNA-21) can be detected by a flexible biosensor.
International Year of Light: Whispering Gallery Mode Microcavities
The fundamentals and the advances in the fabrication methods of whispering gallery mode cavities, as well as their application prospects are presented in this review article.
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.
New composite material enables smaller CO2 sensor
Material scientists at ETH Zurich and the Max Planck Institute of Colloids and Interfaces in Potsdam have developed a new type of sensor to measure CO2.
