Discovery could have big impact on semiconductor industry. A new experimental discovery, led by researchers at the University of Minnesota, demonstrates that the chemical element ruthenium (Ru) is the fourth single element to have unique magnetic properties at room temperature. The discovery could be used to improve sensors, devices in the computer memory and logic industry, or other devices using magnetic materials.

The use of ferromagnetism, or the basic mechanism by which certain materials (such as iron) form permanent magnets or are attracted to m...

Switching with Molecules for Pioneering Electro-Optical Devices

A research team at the Technical University of Munich has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering of devices that could replace silicon-based components with organic molecules. Credit: Yuxiang Gong / TUM / Journal of the American Chemical Society

Imagine a box you plug into the wall that cleans your toxic air and pays you cash. That’s essentially what Vanderbilt University researchers produced after discovering the blueprint for turning CO2 into the most valuable material ever sold – carbon nanotubes with small diameters.

Carbon nanotubes are supermaterials that can be stronger than steel and more conductive than copper. The reason they’re not in every application from batteries to tires is that these amazing properties only show up in the tiniest nanotubes, which are extremely expensive...
