Better Battery Imaging Paves Way for Renewable Energy Future

Iron-Fluoride-Discharge-Li-041715.jpg

In a move that could improve the energy storage of everything from portable electronics to electric microgrids, University of Wisconsin–Madison and Brookhaven National Laboratory researchers have developed a novel X-ray imaging technique to visualize and study the electrochemical reactions in lithium-ion rechargeable batteries containing a new type of material, iron fluoride.

Nondestructive 3-D Imaging of Biological Cells with Sound

APL-Wright-ultrasonics.jpg

In this week’s Applied Physics Letters, researchers from Thailand and Japan describe the first known demonstration of 3-D cell imaging using picosecond ultrasonics, and show that picosecond ultrasonics can achieve micron resolution of single cells, imaging their interiors in slices separated by 150 nanometers. This work is a proof-of-principle that may open the door to new ways of studying the physical properties of living cells by imaging them in vivo.

Giant Magnetic Effects Induced in Hybrid Materials

For a magnetic thin film deposited onto a transition metal oxide film, the magnetic properties change dramatically as the oxide undergoes a structural phase transition. The hybrid between a simple magnetic material and a transition-metal oxide provides a “window” to understand the metal-to-insulator transition and offers dramatic tunability of magnetic properties. Potential applications are envisioned in the fields of information storage and power transmission.

Scientists Develop Mesh That Captures Oil—but Lets Water Through

A mesh with a high-tech coating captures oil while water passes right through. With further development of this technology, the researchers say, "you could potentially catch an oil spill with a net."

New “Cool Roof Time Machine” Will Accelerate Cool Roof Deployment

BerkeleyLabroofagingsmall.jpg

A collaboration led by Berkeley Lab scientists has established a method to simulate in the lab the soiling and weathering of roofing materials, reproducing in only a few days the solar reflectance of roofing products naturally aged for three years. Now this protocol has been approved by ASTM International, a widely referenced standards body, as a standard practice for the industry.
