Design for Magnetoelectric Device May Improve Your Memory

Conventional memory devices use transistors and rely on electric fields to store and read out information. An alternative approach uses magnetic fields, and a promising version relies on the magnetoelectric effect which allows an electric field to switch the magnetic properties of the devices. Existing devices, however, tend to require large magnetic and electric fields. One potential solution is a new switching element made from chromia. The researchers report their findings in Applied Physics Letters.

A Potentially Cheap, Efficient and Eco-Friendly System for Purifying Natural Gas

Fundamental researchers have proposed a novel two-part system for separating impurities from natural gas in the Journal of Renewable and Sustainable Energy. Natural gas primarily contains methane, but impurities in the gaseous mixture need to be removed before the methane can be put into the pipeline. The newly proposed purification system combines two separation methods and, in principle, promises to improve performance, reduce costs and diminish ecological side effects compared to benchmark technologies.
