Research on postelection auditing procedures finds error rates of up to 2 percent Hand counting of votes in postelection audit or recount procedures can result in error rates of up to 2 percent, according to a new study from Rice University and Clemson University. "These procedures are intended as a safeguard against computer and human error, but until recently, no research existed to tell whether these efforts helped or hurt the accuracy of the vote," said Michael Byrne, associate...

Rice University lab uses nanoparticles to increase thermal properties of transformer oil Rice University scientists have created a nano-infused oil that could greatly enhance the ability of devices as large as electrical transformers and as small as microelectronic components to shed excess heat. Research in the lab of Rice materials scientist Pulickel Ajayan, which appears in the American Chemical Society journal ACS Nano, could raise the efficiency of such transformer oils by as much...

Among corporations involved in the 2006 stock-option backdating scandal, those implicated earlier were more likely to dismiss their top executives than those that surfaced later on, according to new research from Rice University and the University of California at Irvine. The study, "Executive Turnover in the Stock-Option Backdating Wave: The Impact of Social Context," will be published in an upcoming edition of the Strategic Management Journal. The researchers examined the behavior of...

Rice University researchers show how length, imperfections affect carbon nanotube fluorescence A painstaking study by Rice University has brought a wealth of new information about single-walled carbon nanotubes through analysis of their fluorescence. The current issue of the American Chemical Society journal ACS Nano features an article about work by the Rice lab of chemist Bruce Weisman to understand how the lengths and imperfections of individual nanotubes affect their fluorescence...

Terahertz polarizer nears perfection Researchers at Rice University are using carbon nanotubes as the critical component of a robust terahertz polarizer that could accelerate the development of new security and communication devices, sensors and non-invasive medical imaging systems as well as fundamental studies of low-dimensional condensed matter systems. The polarizer developed by the Rice lab of Junichiro Kono, a professor of electrical and computer engineering and of physics and...

Rice University researchers first to see superfluorescence from solid-state material In a flash, the world changed for Tim Noe — and for physicists who study what they call many-body problems. The Rice University graduate student was the first to see, in the summer of 2010, proof of a theory that solid-state materials are capable of producing an effect known as superfluorescence. That can only happen when "many bodies" — in this case, electron-hole pairs created in a...

Air Force Research Laboratory experiment shows chirality of tube controls speed of growth The Air Force Research Laboratory in Dayton, Ohio, has experimentally confirmed a theory by Rice University Professor Boris Yakobson that foretold a pair of interesting properties about nanotube growth: That the chirality of a nanotube controls the speed of its growth, and that armchair nanotubes should grow the fastest. The work is a sure step toward defining all the mysteries inherent in what...

Study finds protein's entwined arm movements may control fate of potentially toxic payload Like a magician employing sleight of hand, the protein mitoNEET -- a mysterious but important player in diabetes, cancer and aging -- draws the eye with a flurry of movement in one location while the subtle, more crucial action takes place somewhere else. Using a combination of laboratory experiments and computer modeling, scientists from Rice University and the University of California, San Diego...

[ Watch the Video ] Orbit of captured electron matches orbit of Jupiter's captured asteroids Rice University physicists have gone to extremes to prove that Isaac Newton's classical laws of motion can apply in the atomic world: They've built an accurate model of part of the solar system inside a single atom of potassium. In a new paper published this week in Physical Review Letters, Rice's team and collaborators at the Oak Ridge National Laboratory and the Vienna University of...
