System treats gastroschisis in developing countries

It should go without saying it takes guts to develop a low-cost procedure to treat gastroschisis. A team of Rice University students working on the problem had them in every way. The three members of Team Si-Low built a sophisticated system that would be simple for doctors in developing countries to execute as they help infants born with the condition, in which the abdominal wall is not fully closed and some of the child’s intestines r...

Imaging technique pulls plasmon data together

Rice University scientists have developed a novel technique to view a field of plasmonic nanoparticles simultaneously to learn how their differences change their reactivity. Their new method is called snapshot hyperspectral imaging (SHI), which up to now has been used primarily in astronomy. SHI allows researchers to view minute differences between otherwise identical nanoparticles and see how they react in response to light and environmental cha...

Magnets and nanoparticles open and close gaps in blood vessels

The endothelial cells that line blood vessels are packed tightly to keep blood inside and flowing, but scientists at Rice University and their colleagues have discovered it may be possible to selectively open gaps in those barriers just enough to let large molecules through — and then close them again. Rice bioengineer Gang Bao and collaborators at Emory University and the Georgia Institute of Technology reported using magnets to help ...

Laser-induced graphene suitable as implant material

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 of chemist James Tour developed it three years ago by burning partway through an inexpensive polyimide sheet with a laser, which turned the su...

Turning cement's weakness into strength

The Rice lab of materials scientist Rouzbeh Shahsavari performed an atom-level computer analysis of tobermorite, a naturally occurring crystalline analog to the calcium-silicate-hydrate (C-S-H) that makes up cement, which in turn holds concrete together. By understanding the internal structure of tobermorite, they hope to make concrete stronger, tougher and better able to deform without cracking under stress.

Bumpy surfaces dissipate heat in microelectronics

Bumpy surfaces with graphene between would help dissipate heat in next-gen microelectronic devices, according to Rice University scientists. Their theoretical studies show that enhancing the interface between gallium nitride semiconductors and diamond heat sinks would allow phonons – quasiparticles of sound that also carry heat – to disperse more efficiently. Heat sinks are used to carry heat away from electronic devices.
