Advanced light: Sending entangled beams through fast-light materials

Michael Lewis's bestselling book "Flash Boys" describes how some brokers, engaging in high frequency trading, exploit fast telecommunications to gain fraction-of-a-second advantage in the buying and selling of stocks. But you don't need to have billions of dollars riding on this-second securities transactions to appreciate the importance of fast signal processing. From internet to video streaming, we want things fast.

This image depicts the experimental setup for studying fast light. Pump beams (purple) create correlated probe (turquoise) and conjugate (gold) beams. Each of these beams is aimed at a beam splitter (yellow disks). A local oscillator (LO) also sends a laser beam into each of the beam splitters. The resulting interference pattern -- registered in a spectrum analyzer, SA -- for the probe and conjugate arms are compared.

Scientists use nanoparticles to control growth of materials: UCLA-led team creates 'diet control' technique that could have broad applications in manufacturing and medicine

But it also occurs naturally in chemicals, metals and other inorganic materials. That fact has, for decades, posed a major challenge for scientists and engineers, because controlling the growth within materials is critical for creating products with uniform physical properties so that they can be used as components of machinery and electronic devices. The challenge has been particularly vexing when the materials' molecular building blocks grow rapidly or are processed under harsh conditions such as high temperatures.

Improved Supercapacitors for Super Batteries, Electric Vehicles: Researchers develop novel supercapacitor architecture that provides two times more energy and power compared to supercapacitors commercially available today

Researchers at the University of California, Riverside have developed a novel nanometer scale ruthenium oxide anchored nanocarbon graphene foam architecture that improves the performance of supercapacitors, a development that could mean faster acceleration in electric vehicles and longer battery life in portable electronics.
