Welding Nanowires With Light

Electrically conductive meshes made of metal nanowires promise exceptional electrical throughput, low cost, and easy processing in applications like video displays, LEDs, and thin-film solar cells. However, in processing, these meshes must be heated or pressed to unite the crisscross pattern of nanowires that form the mesh - damaging them in the process.

Quantum Dot Light Enhancement Substrate

A cost-competitive solution for increasing the light extraction efficiency of organic light-emitting diodes (OLEDs) with efficient and stable color rendering index (CRI) for solid-state lighting (SSL) was developed and demonstrated. Solution-processable quantum dot (QD) films were integrated into OLED indium tin oxide (ITO)-glass substrates to generate tunable white emission from blue-emitting OLED devices.

Looking at Atmospheric Stability to Predict Wind Power

Power generated by a wind turbine largely depends on wind speed. In a wind farm in which the turbines experience the same wind speeds but different shapes, such as turbulence, to the wind profile, a turbine will produce different amounts of power. Two researchers say that this variable power can be predicted by looking at atmospheric stability.
