Replacing just one atom gives new powers to biocompatible fluorescent molecules, say researchers. The Rice University lab of chemist Han Xiao reports in the Journal of the American Chemical Society that it has developed a single-atom switch to turn fluorescent…
Gold nanowires. Color added. See the original image here. (Credit: Zubarev Research Group/Rice) Some vitamin C helps turn small gold nanorods into fine gold nanowires, report researchers. Common, mild ascorbic acid is the not-so-secret sauce that helped the Rice…
Electric vehicles, powered by macroscopic electric motors, are increasingly prevalent on our streets and highways. These quiet and eco-friendly machines got their start nearly 200 years ago when physicists took the first tiny steps to bring electric motors into the world.
Venkataraman's group has been studying the fundamental properties of single-molecule devices for almost two decades, exploring the interplay of physics, chemistry, and engineering at the nanometer scale. Her underlying focus is on building single-molecule circuits, a molecule attached to two…
As silicon-based electronics approach fundamental limits, researchers are turning to molecules as the smallest possible functional devices. Molecular electronics replaces conventional transistors with individual molecules that control current through quantum effects rather than classical charge flow. Recent progress shows that…
Scientists have long strived to develop artificial molecular motors that can convert energy into directed motion. Researchers at Linköping University in Sweden have now presented a solution to a... How to shift gears in a molecular motor Scientists have long strived…
Artistic representation of a ladder molecule acting as a component in molecular electronics. This new research, led by Charles Schroeder, the James Economy Professor of Materials Science and Engineering and Professor of Chemical and Biomolecular Engineering, along with postdoc Xiaolin…
Scientists have proposed what they believe is the first way to detect "mirror life," a hypothetical form of life built from molecules that are reversed versions of those found in living organisms on Earth. Researchers from the University of Strathclyde…
The appeal of supercritical carbon dioxide as a processing medium stems from its accessible critical point, with a critical temperature of approximately 31 degrees Celsius and a critical pressure of roughly 74 bar. Above these thresholds, carbon dioxide behaves as
