Iron-Based Superconductor Simulations Spin Out New Possibilities on Titan

Fig13.png

Researchers studying iron-based superconductors are combining novel electronic structure algorithms with the high-performance computing power of the Titan supercomputer to predict spin dynamics, or the ways electrons orient and correlate their spins in a material.

Tough Electronics Based on Bullet-Proof Kevlar

AVS-Atanasov-Kevlar.jpg

A group of North Carolina State University researchers is exploring novel ways to apply semiconductor industry processes to unique substrates to "weave together" multifunctional materials with distinct capabilities. During the AVS 61st International Symposium & Exhibition, they will describe how they were able to "weave" high-strength, highly conductive yarns made of tungsten on Kevlar -- aka body armor material -- by using atomic layer deposition, a process commonly used for producing memory and logic devices.

Nuclear Waste Viewed in New Light

AVS-Scott-uranium.jpg

Britain’s nuclear reactors, stainless steel drums, contain metal-clad spent uranium embedded in concrete, and they are highly radioactive. The only way to handle them safely is from behind 2-to-3-meter-thick concrete walls and leaded glass windows using automated equipment. Yet a very small number of these drums have begun to bulge after many years in storage, raising questions about what is happening within. The only way to know for sure is to sneak a peek inside.

Nanosafety Research: The Quest for the Gold Standard

Empa toxicologist Harald Krug has lambasted his colleagues in the journal Angewandte Chemie. He evaluated several thousand studies on the risks associated with nanoparticles and discovered no end of shortcomings: poorly prepared experiments and results that don’t carry any clout. Instead of merely leveling criticism, however, Empa is also developing new standards for such experiments within an international Network.

“Reverse Engineering” Materials for More Efficient Heating and Cooling

APL-Thermoelectric1-SEM-TristanDay2.jpg

If you’ve gone for a spin in a luxury car and felt your back being warmed or cooled by a seat-based climate control system, then you’ve likely experienced the benefits of a class of materials called thermoelectrics. Thermoelectric materials convert heat into electricity, and vice versa, and have many advantages over traditional heating and cooling systems. Recently, researchers have observed that the performance of some thermoelectric materials can be improved by combining different solid phases.
