Rice University lab calculates unique electronic qualities of double-walled carbon nanotubes
Rice University researchers have determined that two walls are better than one when turning carbon nanotubes into materials like strong, conductive fibers or transistors.Rice materials scientist Enrique Barrera and his colleagues used atomic-level models of double-walled nanotubes to see how they ...
Graphene quantum dots made from coal, introduced in 2013 by the Rice University lab of chemist James Tour, can be engineered for specific semiconducting properties in either of two single-step processes.In a new study this week in the American Chemical Society journal Applied Materials & ...
What lies beneath growing islands of graphene is important to its properties, according to a new study led by Rice University. Scientists at Rice analyzed patterns of graphene - a single-atom-thick sheet of carbon - grown in a furnace via chemical vapor deposition. They discovered that the ...
Rice researchers develop accurate measure of aggregating particles that block oil production lines
Rice University researchers have developed an easy and accurate technique to detect and quantify the amount of asphaltene precipitated from crude oils, which bedevils the oil industry by clogging wells and flow lines.Asphaltene is a complex of hydrocarbon molecules found in crude. As the name ...
Rice physicists build superconductor analog, observe antiferromagnetic order
Using ultracold atoms as a stand-in for electrons, a Rice University-based team of physicists has simulated superconducting materials and made headway on a problem that's vexed physicists for nearly three decades.The research was carried out by an international team of experimental and ...
In Rice University study, treated carbon-60 molecules remove metals from liquids
Treated buckyballs not only remove valuable but potentially toxic metal particles from water and other liquids, but also reserve them for future use, according to scientists at Rice University.The Rice lab of chemist Andrew Barron has discovered that carbon-60 fullerenes (aka buckyballs) that ...
Rice-led study shows how particles quench damaging superoxides
Injectable nanoparticles that could protect an injured person from further damage due to oxidative stress have proven to be astoundingly effective in tests to study their mechanism.Scientists at Rice University, Baylor College of Medicine and the University of Texas Health Science Center at ...
Findings bolster theory that quantum fluctuations drive strange electronic phenomena
A new study by a team of physicists at Rice University, Zhejiang University, Los Alamos National Laboratory, Florida State University and the Max Planck Institute adds to the growing body of evidence supporting a theory that strange electronic behaviors - including high-temperature ...
Rice University lab discovers simple way to make material for energy storage, electronics
Researchers at Rice University have created flexible, patterned sheets of multilayer graphene from a cheap polymer by burning it with a computer-controlled laser. The process works in air at room temperature and eliminates the need for hot furnaces and controlled environments, and it makes ...
Sensor amplifies optical signature of single molecules about 100 billion times
Nanophotonics experts at Rice University have created a unique sensor that amplifies the optical signature of molecules by about 100 billion times. Newly published tests found the device could accurately identify the composition and structure of individual molecules containing fewer than 20 ...
