Salt boosts creation of 2-D materials

23-Apr-2018

A dash of salt can simplify the creation of two-dimensional materials, and thanks to Rice University scientists, the reason is becoming clear. Boris Yakobson, a Rice professor of materials science and nanoengineering and of chemistry, was the go-to expert when a group of labs in Singapore, China, ...

Nature's toughest substances decoded

05-Dec-2017

How a material breaks may be the most important property to consider when designing layered composites that mimic those found in nature. A method by Rice University engineers decodes the interactions between materials and the structures they form and can help maximize their strength, toughness, ...

Nanoshells could deliver more chemo with fewer side effects

13-Nov-2017

Researchers investigating ways to deliver high doses of cancer-killing drugs inside tumors have shown they can use a laser and light-activated gold nanoparticles to remotely trigger the release of approved cancer drugs inside cancer cells in laboratory cultures. The study employed gold nanoshells ...

Laser-induced graphene made from wood

02-Aug-2017

Rice University scientists have made wood into an electrical conductor by turning its surface into graphene. Rice chemist James Tour and his colleagues used a laser to blacken a thin film pattern onto a block of pine. The pattern is laser-induced graphene (LIG), a form of the atom-thin carbon ...

Heavy metals in water meet their match

28-Jul-2017

Carbon nanotubes immobilized in a tuft of quartz fiber have the power to remove toxic heavy metals from water, according to researchers at Rice University. Prize-winning filters produced in the lab of Rice chemist Andrew Barron by then-high school student and lead author Perry Alagappan absorb ...

Indented cement shows unique properties

21-Jul-2017

Rice University scientists have determined that no matter how large or small a piece of tobermorite is, it will respond to loading forces in precisely the same way. But poking it with a sharp point will change its strength. Tobermorite is a naturally occurring crystalline analog to the ...

Fluorine grants white graphene new powers

17-Jul-2017

A little fluorine turns an insulating ceramic known as white graphene into a wide-bandgap semiconductor with magnetic properties. Rice University scientists said that could make the unique material suitable for electronics in extreme environments. A proof-of-concept paper from Rice researchers ...

Zap! Graphene is bad news for bacteria

24-May-2017

Scientists at Rice University and Ben-Gurion University of the Negev (BGU) have discovered that laser-induced graphene (LIG) is a highly effective anti-fouling material and, when electrified, bacteria zapper. LIG is a spongy version of graphene, the single-atom layer of carbon atoms. The Rice lab ...

'Hot' electrons don't mind the gap

10-May-2017

If they're quick about it, "hot" electrons excited in a plasmonic metal can tunnel their way across a nanoscale gap to a neighboring metal. Rice University scientists said the cool part is what happens in the gap. A Rice team discovered those electrons can create a photovoltage about a thousand ...

Graphene foam gets big and tough

16-Feb-2017

A chunk of conductive graphene foam reinforced by carbon nanotubes can support more than 3,000 times its own weight and easily bounce back to its original height, according to Rice University scientists. Better yet, it can be made in just about any shape and size, they reported, demonstrating a ...
