'Squid Skin' Metamaterials Project Yields Vivid Color Display

Jade Boyd, Rice University The quest to create artificial "squid skin" -- camouflaging metamaterials that can "see" colors and automatically blend into the background -- is one step closer to reality, thanks to a breakthrough color-display...

Harnessing Power Of The Sun To Produce Steam
2012-11-19 16:15:14

[WATCH VIDEO: Creating Solar Steam With Nanoparticles] Michael Harper for redOrbit.com — Your Universe Online Scientists from Rice University have created a new technology which can harness the power of the sun and transform it into steam. This new method can even produce steam from icy cold water, making nearly any body of water, large or small, hot or cold, a potential energy source. The details of this new technology have been published in today´s online edition of...

Nanoantennas hold promise for infrared photovoltaics Basic scientific curiosity paid off in unexpected ways when Rice University researchers investigating the fundamental physics of nanomaterials discovered a new technology that could dramatically improve solar energy panels. The research is described in a new paper this week in the journal Science. "We're merging the optics of nanoscale antennas with the electronics of semiconductors," said lead researcher Naomi Halas, Rice's Stanley C....

Rice bioengineers, Baylor College of Medicine and Texas Children's physician-scientists zap tumors with light-activated nanoparticles Rice University bioengineers and physician-scientists at Baylor College of Medicine and Texas Children's Hospital have successfully destroyed tumors of human brain cancer cells in the first animal tests of a minimally invasive treatment that zaps glioma tumors with heat. The tests involved nanoshells, light-activated nanoparticles that are designed to destroy...

Self-assembly method yields materials with unique optical properties Scientists from four U.S. universities have created a way to use Rice University's light-activated nanoshells as building blocks for 2-D and 3-D structures that could find use in chemical sensors, nanolasers and bizarre light-absorbing metamaterials. Much as a child might use Lego blocks to build 3-D models of complex buildings or vehicles, the scientists are using the new chemical self-assembly method to build complex...

Nanoparticle could allow diagnosis, treatment in one visit Researchers at Rice University and Baylor College of Medicine (BCM) have created a single nanoparticle that can be tracked in real time with MRI as it homes in on cancer cells, tags them with a fluorescent dye and kills them with heat. The all-in-one particle is one of the first examples from a growing field called "theranostics" that develops technologies physicians can use to diagnose and treat diseases in a single procedure. The...

U.S. scientists are using computer simulations to study the effect of heating nanoparticles with lasers to kill cancer cells without damaging healthy tissue. Rice University Professor Yildiz Bayazitoglu and doctoral student Jerry Vera said they hope to raise the efficiency of destroying tumors by fine-tuning methods of heating them based on the size and composition of the tumor and surrounding tissue. The researchers said they found attacking a tumor with two lasers can heat it more...

Researchers build computer simulations of laser-nanoparticle treatments Two lasers may be better than one when attacking cancer cells, according to a paper by Rice University scientists. Yildiz Bayazitoglu, Rice's H.S. Cameron Chair Professor of Mechanical Engineering and an authority on heat transfer and fluid flow, and doctoral student Jerry Vera are using computer simulations to quantify the effect of heating nanoparticles with near-infrared lasers to kill cancer tumors without damaging...

Light-bending metamaterial could lead to superlenses, invisibility cloaksResearchers at Rice University have created a metamaterial that could light the way toward high-powered optics, ultra-efficient solar cells and even cloaking devices.Naomi Halas, an award-winning pioneer in nanophotonics, and graduate student Nikolay Mirin created a material that collects light from any direction and emits it in a single direction. The material uses very tiny, cup-shaped particles called nanocups.In a...

By Eric Berger, Houston Chronicle Jul. 31--Graphics * --How nanoshells burn away tumors Blogs * --SciGuy introduces a new science blog: Evo.Sphere The buzz surrounding gold nanoshells, a radical new approach to treating cancer, began shortly after their creation in Houston a decade ago. The work by Rice University scientists prompted U.S. Rep. John Culberson, a nanotechnology enthusiast whose district includes Rice, to declare that cancer was "cured." And when the National...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
