By doping a thermoelectric material with minute amounts of sulfur, a team has found a new path to large improvements in the efficiency of materials for solid-state heating and cooling and waste energy recapture...

Researchers determined that using integrated circuits, including one shown right of the US quarter and below the label ‘CHIP1’ in an electronic nose will make the device more affordable. Credit: UT Dallas

Researchers at Texas Analog Center of Excellence (TxACE) at UT Dallas are working to develop an affordable electronic nose that can be used in breath analysis for a wide range of health diagnosis. While devices that can conduct breath analysis using compound semiconductors exist, they are bulky and too costly for commercial use. The researchers determined that using CMOS integrated circuits technology will make the electronic nose more affordable.

CMOS is the integrated circuits technology used to manufacture the bulk of electronics that have made smartphones, tablets and other devices po...

With four moving rows of magnets, the Delta undulator can create circularly polarized, or spiraling, light. Credit: SLAC National Accelerator Laboratory

A new device at the Dept of Energy’s SLAC National Accelerator Lab allows researchers to explore the properties and dynamics of molecules with circularly polarized, or spiraling, light. The use of polarized light is important in the study of many molecules and processes that affect our everyday lives...

Moderate heating up to 80 °Celsius tilts the magnetic moment associated to a single bit into the plane. Upon cooling to room temperature, the magnetic moment stays in plane, until it is overwritten by a magnetic writing head. Credit: HZB

It paves the way to fast and energy efficient ultrahigh density data storage. Scientists have examined thin films of Dysprosium-Cobalt sputtered onto a nanostructured membrane at BESSY II. New patterns of magnetization could be written in a quick and easy manner after warming the sample to only 80C, which is a much lower temperature as compared to conventional Heat Assisted Magnetic Recording systems.

To increase data density further in storage media, materials systems with stable magnetic domains on the nanoscale are needed...
