Collective, fast diffusion observed by Ames Laboratory team could represent a new way to grow perfect, tiny metal nanostructures.

If you’re allergic to natural rubber latex, the U.S. Food and Drug Administration has good news for you: in the future, you are less likely to be misinformed about the absence of this allergen in such products as medical devices. To avoid false assurances about this hazard to your health, FDA is recommending to manufacturers to stop using the labels “latex-free” or “does not contain latex.”

Researchers at the University of Texas at Dallas have created new structures that exploit the electromechanical properties of specific nanofibers to stretch to up to seven times their length, while remaining tougher than Kevlar.

The Critical Materials Institute, a U.S. Department of Energy Innovation Hub led by the Ames Labratory, has created a new chemical process that makes use of the widely available rare-earth metal cerium to improve the manufacture of nylon.

Less than 1 percent of Earth’s water is drinkable. Removing salt and other minerals from our biggest available source of water—seawater—may help satisfy a growing global population thirsty for fresh water for drinking, farming, transportation, heating, cooling and industry. But desalination is an energy-intensive process, which concerns those wanting to expand its application.

By figuring out how to precisely order the molecules that make up what scientists call organic glass — the materials at the heart of some electronic displays, light-emitting diodes and solar cells — a team of chemists from the University of Wisconsin-Madison has set the stage for more efficient and sturdier portable electronic devices and possibly a new generation of solar cells based on organic materials.

University of Washington scientists have built a new nanometer-sized laser — using the thinnest semiconductor available today — that is energy efficient, easy to build and compatible with existing electronics.
