Catalyst holds promise for clean, inexpensive hydrogen production
Graphene doped with nitrogen and augmented with cobalt atoms has proven to be an effective, durable catalyst for the production of hydrogen from water, according to scientists at Rice University. The Rice lab of chemist James Tour and colleagues at the Chinese Academy of Sciences, the University ...
Cars appear to produce carbon nanotubes, and some of the evidence has been found in human lungs
Rice University scientists working with colleagues in France have detected the presence of man-made carbon nanotubes in cells extracted from the airways of Parisian children under routine treatment for asthma. Further investigation found similar nanotubes in samples from the exhaust pipes of ...
In a great example of "less is more," Rice University scientists have developed a powerful method to analyze carbon nanotubes in solution. The researchers' variance spectroscopy technique zooms in on small regions in dilute nanotube solutions to take quick spectral snapshots. By analyzing the ...
Rice University researchers have demonstrated an efficient new way to capture the energy from sunlight and convert it into clean, renewable energy by splitting water molecules. The technology relies on a configuration of light-activated gold nanoparticles that harvest sunlight and transfer solar ...
Theorists show flat boron form would depend on metal substrates
Scientists have theoretically determined that the properties of atom-thick sheets of boron depend on where those atoms land. Calculation of the atom-by-atom energies involved in creating a sheet of boron revealed that the metal substrate - the surface upon which two-dimensional materials are ...
Rice University chemists who developed a unique form of graphene have found a way to embed metallic nanoparticles that turn the material into a useful catalyst for fuel cells and other applications. Laser-induced graphene, created by the Rice lab of chemist James Tour last year, is a flexible ...
Rice University scientists make tantalum oxide practical for high-density devices
Scientists at Rice University have created a solid-state memory technology that allows for high-density storage with a minimum incidence of computer errors. The memories are based on tantalum oxide, a common insulator in electronics. Applying voltage to a 250-nanometer-thick sandwich of graphene, ...
Scientists find 3-D boron nitride structures will excel at thermal management for electronics
Three-dimensional structures of boron nitride might be the right stuff to keep small electronics cool, according to scientists at Rice University. Rice researchers Rouzbeh Shahsavari and Navid Sakhavand have completed the first theoretical analysis of how 3-D boron nitride might be used as a ...
What if peanut brittle, under certain conditions, behaved like taffy? Something like that happens to a two-dimensional dichalcogenide analyzed by scientists at Rice University.Rice researchers calculated that atomically thin layers of molybdenum disulfide can take on the qualities of plastic ...
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 ...
