To be more energy efficient, many people have replaced their incandescent lights with light-emitting diode (LED) bulbs.
A lucky break has shown silicon is a powerful material for use in the manipulation of light.
Scientists have discovered a new technique to measure the distribution of compositional changes in the indium gallium nitride (InGaN) quantum wells (QWs) at varying amounts of indium.
The inclusion of a special new perovskite layer has enabled scientists to create a "spin-polarized LED" without needing a magnetic field or extremely low temperatures, potentially clearing the path to a raft of novel technologies.
Energy-efficient light-emitting diodes (LEDs) have been used in our everyday life for many decades. But the quest for better LEDs, offering both lower costs and brighter colours, has recently drawn scientists to a material called perovskite. A recent joint-research project co-led by the scientist from City University of Hong Kong (CityU) has now developed a 2D perovskite material for the most efficient LEDs.
Researchers from University College London (UCL) and the Istituto Italiano di Tecnologia (Italian Institute of Technology—IIT) have made a temporary tattoo using light-emitting technology found in smartphone and TV screens. The study sets the stage for a new kind of “smart tattoo” with several possible applications.
Living in a group has clear benefits. As a member of a societal group, one can share resources with the others, seek protection from predators, and forage in an efficient manner.
Teledyne Imaging, a group within Teledyne Technologies, and manufacturer and developer of digital cameras for industrial and scientific imaging, is pleased to announce the release of its new 20 megapixel Lt Series USB3 cameras. Like all Lt Series models, these newest cameras have a robust and compact enclosure, fully locking USB3 connectors, and are built for rugged 24/7 use. They are available from Teledyne Lumenera, a part of the Teledyne Imaging Group.
Imec, a world-leading research and innovation hub in nanoelectronics and digital technologies, reports for the first time the use of a 13.5 nm High Harmonic Generation source for the printing of 20 nm pitch line/spaces using interference lithographic imaging of an Inpria metal-oxide resist under high-numerical-aperture (high-NA) conditions.
The new All-Rounder ITS camera is engineered with an all-in-one structure, embedding video, radar, and supplemental light in one module, helping traffic authorities to easily ramp up the detection of violations
