NUS physicists have discovered that recovered carbon black powder can be transformed by laser treatment to give a wide range of colours for potential display applications. Recovered carbon black powder is a common pigment produced from scrap rubber tyres. There is a growing demand to use it as an environmentally friendly and sustainable material as […]

A Hole in One for Holographic Display
Researchers in Korea have designed an ultrathin display that can project dynamic, multi-colored, 3D holographic images, according to a study published in Nature Communications. The system’s critical component is a thin film of titanium filled with tiny holes that precisely correspond with each pixel in a liquid crystal display (LCD) panel. This film acts as a […]
NRL Develops Laser Processing Method to Increase Efficiency of Optoelectronic Devices
Scientists at the U.S. Naval Research Laboratory (NRL) discovered a new method to passivate defects in next generation optical materials to improve optical quality and enable the miniaturization of light emitting diodes and other optical elements. “From a chemistry standpoint, we have discovered a new photocatalytic reaction using laser light and water molecules, which is […]
Panasonic Unveils Transparent OLED Concept Display
At Italy’s Salone del Mobile furniture and lifestyle exhibition, Panasonic unveiled a transparent OLED concept display, which was part of an installation by Swiss furniture brand Vitra. If you walk by the structure, it resembles an ordinary glass cabinet with a wooden frame. But once the device is powered on, the glass reveals its true […]
Largest, Fastest Array of Microscopic ‘Traffic Cops’ for Optical Communications
Engineers at the University of California, Berkeley have built a new photonic switch that can control the direction of light passing through optical fibers faster and more efficiently than ever. This optical “traffic cop” could one day revolutionize how information travels through data centers and high-performance supercomputers that are used for artificial intelligence and other […]
Touch-Free UI Solutions with Capacitive Touch-Key Microcontrollers for 2D/3D Gesture Control
Renesas Electronics Corporation introduced two touch-free user interface (UI) solutions to simplify the design of 2D and 3D control-based applications. Based on Renesas’ capacitive sensor microcontrollers (MCUs), the new solutions support the development of UI that allows users to operate home appliances, as well as industrial and OA equipment without touching the devices. The UI […]
Bionics: Electric View in Murky Waters
When dealing with disasters or searching for objects, robots or drones with cameras are usually used. However, conventional cameras are of rather limited use in murky, dark water, such as in a sewage pipe or a lake that is cloudy with sediment. Zoologists at the University of Bonn have now developed a special camera for […]
Photons Trained for Optical Fibre Obstacle Course Will Deliver Stronger Cyber Security
Beneath many cities are complex networks of optical fibres that carry data, encoded in pulses of light, to offices and homes. Researchers from the National University of Singapore (NUS) and Singtel, Asia’s leading communications technology group, have demonstrated a technique that will help pairs of light particles smoothly navigate these networks, a breakthrough that will […]
Record Efficiency for Perovskite-Based Light-Emitting Diodes
Efficient near-infrared (NIR) light-emitting diodes of perovskite have been produced in a laboratory at Linköping University. The external quantum efficiency is 21.6%, which is a record. The results have been published in Nature Photonics. The work is led by LiU scientist Feng Gao, in close collaboration with colleagues in China, Italy, Singapore and Switzerland. Perovskites are […]
Physicists Create Star Trek-Style Holograms
Star Trek‘s famous holodeck is a virtual reality stage that simulates any object in 3-D as if they were real. However, 3-D holographic projection has never been realized. A team of scientists from Bilkent University, Turkey, has now demonstrated the first realistic 3-D holograms that can be viewed from any angle. Now, a team at […]
