Schematic representation of a processor for matrix multiplications which runs on light. Credit: University of Oxford The exponential growth of data traffic in our digital age poses some real challenges on processing power. And with the advent of machine learning and AI in, for example, self-driving vehicles and speech recognition, […]

The solar cell created by the team is transparent, allowing its use in a wide range of applications. Credit: Joondong Kim from Incheon National University A new study led by scientists from Incheon National University in Korea shows how to make a fully transparent solar cell. In a new study […]

Graphene hybrid made from metal organic frameworks (MOF) and graphenic acid make an excellent positive electrode for supercapacitors, which thus achieve an energy density similar to that of nickel-metal hydride batteries.

Highly efficient, pure-blue organic light-emitting diodes (OLEDs) developed by researchers at Kyushu University in Japan are being tested to measure their lifetime. Based on hyperfluorescence, which uses a two-molecule process to emit light, the OLEDs emit pure-blue emission and exhibit significantly improved lifetimes compared to other highly efficient devices, all […]

: MIT researchers have found that an alloy material called InGaAs could be suitable for high-performance computer transistors. If operated at high-frequencies, InGaAs transistors could one day rival silicon. This image shows a solid state memory wafer traditionally made of silicon.

The four transistors on this chip were built out of a 2D material that disguises them from hackers. Credit: Purdue University photo/John Underwood A hacker can reproduce a circuit on a chip by discovering what key transistors are doing in a circuit – but not if the transistor “type” is […]

By copying the multilayer geometry of mammal bones, cathodes for sodium-ion batteries can be made more structurally stable, while maintaining high capacities and fast charge rates. Sodium-ion batteries are poised to replace lithium-ion batteries for large-scale electrical energy storage. They offer several advantages over lithium-ion batteries, particularly due to the […]

Illinois researchers developed a spherical lens that allows light coming into the lens from any direction to be focused into a very small spot on the surface of the lens exactly opposite the input direction. This is the first time such a lens has been made for visible light. Credit: […]

An artist’s rendition of the photoacoustic airborne sonar system operating from a drone to sense and image underwater objects. Credit: Kindea Labs The “Photoacoustic Airborne Sonar System” could be installed beneath drones to enable aerial underwater surveys and high-resolution mapping of the deep ocean. Stanford University engineers have developed an […]
