A Cornell Univ. team has developed cotton threads that can conduct electric current as well as a metal wire can, yet remain light and comfortable enough to give a whole new meaning to multi-use garments.

Yale Univ. scientists have developed a magnetic solder that can be manipulated in three dimensions and selectively heated, and offers a more environmentally friendly alternative to today’s lead-based solders.

A team led by Univ. of Wisconsin-Madison researchers has developed a new approach for creating powerful nanodevices, and their discoveries could pave the way for other researchers to begin more widespread development of these devices.

Chemists in Finland have made new polymer-stabilized silver nanoparticles that they say significantly reduce the exposure to silver encountered by those who use silver’s ability to neutralize microbial contaminants, for example in colloidal silver water filters. Though silver’s health benefits are well known, the long-term exposure effects of small amounts of the toxin are not entirely understood.

Researchers at North Carolina Univ. have developed a “metal foam” that has a similar elasticity to bone, which could mean a new generation of biomedical implants that would avoid bone rejection that often results from more rigid implant materials, such as titanium.

Researchers at the California Institute of Technology (Caltech) have developed a way to make some notoriously brittle materials ductile—yet stronger than ever—simply by reducing their size.

Employing some of the world’s most powerful supercomputers, scientists at Lawrence Berkeley National Laboratory have shown that mismatched alloys are a good match for the future development of high performance thermoelectric devices. Thermoelectrics hold enormous potential for green energy production because of their ability to convert heat into electricity.

Physicists have long wondered whether hydrogen could be transformed into a metal and possibly even a superconductor. High-pressure researchers have now modeled three hydrogen-dense metal alloys and found there are pressure and temperature trends associated with the superconducting state—a huge boost in the understanding of how this abundant material could be harnessed.

Gold’s non-toxic nature had led to much experimentation with nanostructures made from this metal. But until recent efforts by NIST scientists, there were no guidelines as to how nanoparticle size would affect interactions with proteins. These observations of behavior may help designers produce predictable effects in potential medical applications.

What’s an MOF? It’s a metal-organic framework--a combination of metal and organic materials with molecular-scale pores that boast a high surface area and great potential for catalytic activity. Argonne Lab research into one promising example, ZIF-8, shows that such structures can be tailored to specific purposes by exerting industrially-accessible high pressure, changing the compound’s structure.
