Researchers at Rensselaer Polytechnic Institute have developed a new technique for growing slimmer copper nanorods, a key step for advancing integrated 3-D chip technology. These thinner copper nanorods fuse together, or anneal, at about 300 degrees Celsius. This relatively low annealing temperature could make the nanorods ideal for use in heat-sensitive nanoelectronics, particularly for "gluing" together the stacked components of 3-D computer chips. "When fabricating and assembling 3-D...

U.S. chemists say they've discovered a technology that permits them to produce ultra-pure gold nanorods that are about 99 percent pure. "The content of high-aspect-ratio gold nanorods produced by today's best synthetic methods is only about 20 percent," said Rice University Assistant Professor Eugene Zubarev, who is leading the research. "A nanoparticle's shape plays a crucial role in determining many of its physical and chemical properties, so when four out of five particles in a batch are...

By Larry Rulison, Albany Times Union, N.Y. Jul. 4--TROY -- An associate professor at Rensselaer Polytechnic Institute has figured out a way to make a pot of water boil more quickly. Nikhil Koratkar and a team of researchers at RPI lined a pot with tiny copper nanorods. They found that the copper material more effectively induced the "phase change" that occurs when the pot is heated to the boiling point, turning the water to vapor. The resulting benefit is that less energy is required...

Nanomaterials are increasingly gaining the attention of not only the scientific community, but also the public due to their unique properties which endear them to new and exciting applications. These special properties can vary markedly from those of the analogous bulk materials. The physical and chemical properties of the nanomaterials tend to be exceptionally closely dependent on their size and shape or morphology. As a result, materials scientists are focusing their efforts on developing...

WEST LAFAYETTE, Ind. "“ Researchers at Purdue University have taken a step toward developing a new type of ultra-sensitive medical imaging technique that works by shining a laser through the skin to detect tiny gold nanorods injected into the bloodstream. In tests with mice, the nanorods yielded images nearly 60 times brighter than conventional fluorescent dyes, including rhodamine, commonly used for a wide range of biological imaging to study the inner workings of cells and molecules....

Nanorods of many materials are proving very successful, and their properties often exceed that of nanotubes, making them excellent candidates for industrial applications. Theoretical calculations predicted that diamond nanorods too would have properties superior to that of carbon nanotubes. But, so far, nobody had been able to actually synthesize diamond nanorods. This is no longer true. A team from the Bayerisches Geoinstitut (Universität Bayreuth) has just reported the synthesis of...
