Capacitor breakthrough


Oct. 21, 2015, was the day that Doc Brown and Marty McFly landed in the future in their DeLorean, with time travel made possible by a "flux capacitor." While the flux capacitor still conjures sci-fi images, capacitors are now key components of portable electronics, computing systems, and electric ...

Are cars nanotube factories on wheels?

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 ...

New approach for 'nanohoops' could energize future devices


When Ramesh Jasti began making tiny organic circular structures using carbon atoms, the idea was to improve carbon nanotubes being developed for use in electronics or optical devices. He quickly realized, however, that his technique might also roll solo. In a new paper, Jasti and five University ...

Smaller is better for nanotube analysis


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 ...

Better trap for greenhouse gases


Emissions from the combustion of fossil fuels like coal, petroleum and natural gas tend to collect within Earth's atmosphere as "greenhouse gases" that are blamed for escalating global warming. So researchers around the globe are on a quest for materials capable of capturing and storing ...


Realizing carbon nanotube integrated circuits


Individual transistors made from carbon nanotubes are faster and more energy efficient than those made from other materials. Going from a single transistor to an integrated circuit full of transistors, however, is a giant leap. "A single microprocessor has a billion transistors in it," said ...


New nanomaterial maintains conductivity in three dimensions


An international team of scientists has developed what may be the first one-step process for making seamless carbon-based nanomaterials that possess superior thermal, electrical and mechanical properties in three dimensions. In early testing, a three-dimensional (3D) fiber-like supercapacitor ...


Physicists precisely measure interaction between atoms and carbon surfaces


Physicists at the University of Washington have conducted the most precise and controlled measurements yet of the interaction between the atoms and molecules that comprise air and the type of carbon surface used in battery electrodes and air filters - key information for improving those ...


'Microcombing' creates stronger, more conductive carbon nanotube films


Researchers from North Carolina State University and China's Suzhou Institute of Nano-Science and Nano-Biotics have developed an inexpensive technique called "microcombing" to align carbon nanotubes (CNTs), which can be used to create large, pure CNT films that are stronger than any previous such ...

Nanotubes with 2 walls have singular qualities

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 ...
