Graphene forms under microscope's eye

Scientists shrink laser-induced graphene for flexible electronics

14-Feb-2020

You don't need a big laser to make laser-induced graphene (LIG). Scientists at Rice University, the University of Tennessee, Knoxville (UT Knoxville) and Oak Ridge National Laboratory (ORNL) are using a very small visible beam to burn the foamy form of carbon into microscopic patterns. The labs ...

Less may be more in next-gen batteries

24-Jan-2020

The process of developing better rechargeable batteries may be cloudy, but there's an alumina lining. A slim layer of the metal oxide applied to common cathodes by engineers at Rice University's Brown School of Engineering revealed new phenomena that could lead to batteries that are better geared ...

A new look at 'strange metals'

20-Jan-2020

For years, a new synthesis method has been developed at TU Wien (Vienna) to unlock the secrets of "strange metals". Now a breakthrough has been achieved. Superconductors allow electrical current to flow without any resistance - but only below a certain critical temperature. Many materials have to ...

Not so fast: Some batteries can be pushed too far

Scientists find overabundance of intentional defects can cause battery cathodes to fail

16-Jan-2020

Intentional defects in batteries have given Rice University scientists a window into the hazards of pushing lithium-ion cells too far. New simulations by Rice materials scientist Ming Tang and graduate student Kaiqi Yang, detailed in the Journal of Materials Chemistry A, shows too much stress in ...

Old newspapers can be used to grow carbon nanotubes

27-Nov-2019

A research collaboration between Rice University and the Energy Safety Research Institute (ESRI) at Swansea University has found that old newspapers can be used as a low cost, eco-friendly material on which to grow single walled carbon nanotubes on a large scale. Carbon nanotubes are tiny ...

Ammonia synthesis made easy with 2D catalyst

Scientists develop inorganic process for small-scale production

27-Nov-2019

Rice University researchers have developed an inorganic method to synthesize ammonia that is both environmentally friendly and can produce the valuable chemical on demand under ambient conditions. The Brown School of Engineering lab of materials scientist Jun Lou manipulated a two-dimensional ...

Nano bulb lights novel path

Rice University engineers create tunable, nanoscale, incandescent light source

23-Sep-2019

What may be viewed as the world's smallest incandescent lightbulb is shining in a Rice University engineering laboratory with the promise of advances in sensing, photonics and perhaps computing platforms beyond the limitations of silicon. Gururaj Naik of Rice's Brown School of Engineering and ...

Chemists show it's hip to be square

Their synthetic azetidines could help simplify drug design for neurological diseases

13-Aug-2019

Rice University chemists want to make a point: Nitrogen atoms are for squares. The nitrogens are the point. The squares are the frames that carry them. These molecules are called azetidines, and they can be used as building blocks in drug design. The Rice lab of chemist László Kürti introduced ...

Chemists produce simple fluorescent surfactants

Compounds show promise for use in medicine, manufacturing

07-Aug-2019

Laboratories use surfactants to separate things, and fluorescent dyes to see things. Rice University chemists have combined the two to simplify life for scientists everywhere. The Wiess School of Natural Sciences lab of chemist Angel Martí introduced a lineup of eight fluorescent surfactants in ...

Oddball edge wins nanotube faceoff

02-Aug-2019

When is a circle less stable than a jagged loop? Apparently when you're talking about carbon nanotubes. Rice University theoretical researchers have discovered that nanotubes with segregated sections of "zigzag" and "armchair" facets growing from a solid catalyst are far more energetically stable ...
