Defects are perfect in laser-induced graphene

Rice University lab discovers simple way to make material for energy storage, electronics

12-12-2014

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 ...

Rice nanophotonics experts create powerful molecular sensor

Sensor amplifies optical signature of single molecules about 100 billion times

23-07-2014

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 ...

Quantum criticality observed in new class of materials

06-06-2014

Quantum criticality, the strange electronic state that may be intimately related to high-temperature superconductivity, is notoriously difficult to study. But a new discovery of "quantum critical points" could allow physicists to develop a classification scheme for quantum criticality - the first ...

Rice University produces carbon-capture breakthrough

Porous material polymerizes carbon dioxide at natural gas wellheads

05-06-2014

Rice University scientists have created an Earth-friendly way to separate carbon dioxide from natural gas at wellheads. A porous material invented by the Rice lab of chemist James Tour sequesters carbon dioxide, a greenhouse gas, at ambient temperature with pressure provided by the wellhead and ...

Not all diamonds are forever

Rice University researchers see nanodiamonds created in coal fade away in seconds

28-05-2014

The Rice researchers behind a new study that explains the creation of nanodiamonds in treated coal also show that some microscopic diamonds only last seconds before fading back into less-structured forms of carbon under the impact of an electron beam. The research by Rice chemist Ed Billups and ...

Graphene only as strong as weakest link

Rice, Georgia Tech experiments determine real-world limits of 2-dimensional carbon

02-05-2014

There is no disputing graphene is strong. But new research by Rice University and the Georgia Institute of Technology should prompt manufacturers to look a little deeper as they consider the miracle material for applications. The atom-thick sheet of carbon discovered this century is touted not ...

Rebar technique strengthens case for graphene

Rice University lab makes hybrid nanotube-graphene material that promises to simplify manufacturing

09-04-2014

Carbon nanotubes are reinforcing bars that make two-dimensional graphene much easier to handle in a new hybrid material grown by researchers at Rice University. The Rice lab of chemist James Tour set nanotubes into graphene in a way that not only mimics how steel rebar is used in concrete but ...

Nanotracer tester tells about wells

Rice University lab builds rig to evaluate oil, gas wells in fracturing operations

26-02-2014

A tabletop device invented at Rice University can tell how efficiently a nanoparticle would travel through a well and may provide a wealth of information for oil and gas producers. The device gathers data on how tracers – microscopic particles that can be pumped into and recovered from wells – ...

A faster way to flag bacteria-tainted food — and prevent illness

21-02-2014

The regular appearance of food poisoning in the news, including a recent event that led to the recall of more than 33,000 pounds of chicken, drives home the need for better bacterial detection long before meats and produce make it to the dinner table. On the horizon is a new approach for pathogen ...

Carbon nanotube fibers outperform copper

Tests show bundles beat traditional cables for transmitting electricity

18-02-2014

On a pound-per-pound basis, carbon nanotube-based fibers invented at Rice University have greater capacity to carry electrical current than copper cables of the same mass, according to new research. While individual nanotubes are capable of transmitting nearly 1,000 times more current than ...
