A Northwestern University research team has revealed a new approach to conducting chemical reactions -- one that doesn't require direct contact with a catalyst. In typical catalytic reactions, the catalyst - the substance that increases the rate of a chemical reaction - and the substrate ...
Simple photochemical method takes advantage of quantum mechanics
Northwestern University chemists have used visible light and extremely tiny nanoparticles to quickly and simply make molecules that are of the same class as many lead compounds for drug development. Driven by light, the nanoparticle catalysts perform chemical reactions with very specific chemical ...
New technology gives insight into how nanomaterials form and grow
A new form of electron microscopy allows researchers to examine nanoscale tubular materials while they are "alive" and forming liquids -- a first in the field. Developed by a multidisciplinary team at Northwestern University and the University of Tennessee, the new technique, called variable ...
Discovery illuminates how bacteria turn methane gas into liquid methanol
Known for their ability to remove methane from the environment and convert it into a usable fuel, methanotrophic bacteria have long fascinated researchers. But how, exactly, these bacteria naturally perform such a complex reaction has been a mystery. Now an interdisciplinary team at Northwestern ...
Coating for metals rapidly heals over scratches and scrapes to prevent corrosion
It's hard to believe that a tiny crack could take down a gigantic metal structure. But sometimes bridges collapse, pipelines rupture and fuselages detach from airplanes due to hard-to-detect corrosion in tiny cracks, scratches and dents. A Northwestern University team has developed a new coating ...
Analyzing oxide films at atomic level
Corrosion is an age-old problem that is estimated to cost about $1 trillion a year, or about 5 percent of the U.S. gross domestic product. Corrosion of metals can be particularly bad, but fortunately they are normally protected from catastrophic damage by naturally forming, super-thin oxide ...
Applications in water purification, solar energy storage, body armor possible
Synthetic polymers are ubiquitous -- nylon, polyester, Teflon and epoxy, to name just a few -- and these polymers are all long, linear structures that tangle into imprecise structures. Chemists have long dreamed of making polymers with two-dimensional, grid-like structures, but this goal has ...
Northwestern University's Jiaxing Huang is ready to reignite carbon nanotube research. And he's doing so with a common chemical that was once used in household cleaners. By using an inexpensive, already mass produced, simple solvent called cresol, Huang has discovered a way to make disperse ...
If you combine two or three metals together, you will get an alloy that usually looks and acts like a metal, with its atoms arranged in rigid geometric patterns. But once in a while, under just the right conditions, you get something entirely new: a futuristic alloy called metallic glass. The ...
New formula works as well as commercial permanent dyes without chemically altering hairs
It's an issue that has plagued the beauty industry for more than a century: Dying hair too often can irreparably damage your silky strands. Now a Northwestern University team has used materials science to solve this age-old problem. The team has leveraged super material graphene to develop a new ...
