Bending light around tight corners without backscattering losses

11 hours 1 min ago
Researchers demonstrate a new optical waveguide capable of bending photons around tight corners on a smaller scale than previously possible. The technology is made possible by through photonic crystals using the concept of topological insulators.

Electronic skin points the way north

Thu, 2018-11-15 21:15
Researchers have developed an electronic skin (e-skin) with magnetosensitive capabilities, sensitive enough to detect and digitize body motion in the Earth's magnetic field. As this e-skin is extremely thin and malleable, it can easily be affixed to human skin to create a bionic analog of a compass. This might not only help people with orientation issues, but also facilitate interaction with objects in virtual and augmented reality.

Epoxy compound gets a graphene bump

Wed, 2018-11-14 22:33
Researchers combine epoxy with a tough graphene foam and carbon nanotube scaffold to build a resilient composite that's tougher and as conductive as other compounds but as light as pure epoxy.

Scientists shed light on semiconductor degradation mechanism

Tue, 2018-11-13 22:24
SiC-based electrical devices degrading will be improved by controlling the semiconductor material deformation with atomic level.

Detecting light in a 'different dimension'

Tue, 2018-11-13 21:33
Scientists have dramatically improved the response of graphene to light through self-assembling wire-like nanostructures that conduct electricity.

Study opens route to ultra-low-power microchips

Tue, 2018-11-13 05:48
Researchers have developed a new way of controlling magnetism in materials, which could lead to new low-power technologies for memory, computing, and sensing devices.

New records in perovskite-silicon tandem solar cells through improved light management

Mon, 2018-11-12 23:46
Using microstructured layers, a team has been able to increase the efficiency of perovskite-silicon tandem solar cells, achieving 25.5 %, which is the highest published value to date. At the same time, computational simulations were utilized to investigate light conversion in various device designs with different nanostructured surfaces. This enabled optimization of light management and detailed energy yield analyses.

Creating better devices: The etch stops here

Fri, 2018-11-09 03:13
Researchers have discovered a new, more precise method to create nanoscale-size electromechanical devices.

Materials scientist creates fabric alternative to batteries for wearable devices

Fri, 2018-11-09 03:12
A major factor holding back development of wearable biosensors for health monitoring is the lack of a lightweight, long-lasting power supply. Now scientists report that they have developed a method for making a charge-storing system that is easily integrated into clothing for 'embroidering a charge-storing pattern onto any garment.'
