Scanning electron micrograph image of germanium nanowires electrodeposited onto an indium-tin oxide electrode from an aqueous solution.

Researchers at Missouri University of Science and Technology have developed what they call “a simple, one-step method” to grow nanowires of germanium from an aqueous solution. Their process could make it more feasible to use germanium in lithium-ion batteries. [Read more…]

Yue-Wern Huang, professor of biological sciences at Missouri S&T.

Nanoparticles are used in all kinds of applications — electronics, medicine, cosmetics, even environmental clean-ups. More than 2,800 commercially available applications are now based on nanoparticles, and by 2017, the field is expected to bring in nearly $50 billion worldwide.

Researchers design nanometer-scale material that can speed up, squeeze light

The cross-section of a 100-nanometer-long “meta-atom” of gold and silicon oxide. Researchers say the meta-atom is capable of straightening and speeding up light waves.

In a process comparable to squeezing an elephant through a pinhole, researchers at Missouri University of Science and Technology have designed a way to engineer atoms capable of funneling light through ultra-small channels.

Connecting the (quantum) dots

Imagine if your office laser printer could print text the size of atoms, then embed that ink into a writing surface as light as air. That, in a sense, is what researchers at UMR have done with a new "laser writing" technique they have developed. But with this process, the "ink" is a semiconductor that could write a new chapter in the field of micro-computing.
