Berkeley Researchers Take the Lead Out of Piezoelectrics
There is good news for the global effort to reduce the amount of lead in the environment and for the growing array of technologies that rely upon the piezoelectric effect. view more (2009-11-16)
Is bismuth a safe medicine for the treatment peptic ulcer disease?
Bismuth compounds have been used for centuries in medicine. The discovery of H. pylori in 1983 led to renewed interest in bismuth compounds, because these were found to successfully treat the infection in combination with antibiotics. view more (2009-01-05)
Multiferroics -- making a switch the electric way
Multiferroics are materials in which unique combinations of electric and magnetic properties can simultaneously coexist. view more (2009-05-26)
Domain Walls that Conduct Electricity
The logic and memory functions of future electronic devices could shrink dramatically - to one or two nanometers (billionths of a meter) instead of the many tens of nanometers that characterize today's most advanced elements - if a way can be found to control domain walls, the ultrathin transition zones that separate regions of a material having... view more...

The Lightness of Electrons in a Twisting Metal Crystal
A team of researchers at Princeton University's Materials Research Science and Engineering Center has observed electrons moving through a crystal of bismuth metal behaving like light. view more (2008-07-28)
Princeton scientists spy an electron dance
A team of scientists led by researchers from Princeton University has discovered a new way that electrons behave in materials. The discovery could lead to new kinds of electronic devices. view more (2008-07-28)
New Exotic Material Could Revolutionize Electronics
Move over, silicon-it may be time to give the Valley a new name. Physicists at the Department of Energy's (DOE) SLAC National Accelerator Laboratory and Stanford University have confirmed the existence of a type of material that could one day provide dramatically faster, more efficient computer chips. view more (2009-06-16)
Appropriate timing in the use of breast shields in children can further reduce MDCT radiation dose
Using breast shields during pediatric chest MDCT reduces radiation dose and minimally increases image noise, according to a recent study conducted by researchers at Duke University Medical Center in Durham, NC and the University of Arkansas for Medical Sciences and Arkansas Children's Hospital in Little Rock. view more (2008-02-13)
Road to greener chemistry paved with nano-gold, researchers report
The selective oxidation processes that are used to make compounds contained in agrochemicals, pharmaceuticals and other chemical products can be accomplished more cleanly and more efficiently with gold nanoparticle catalysts, researchers have reported in Nature magazine. view more (2005-10-26)
Hot On The Heels Of Oil Pollution
Who spilled the oil? This is not an idle inquiry especially when the damage is enormous. To catch the culprits red-handed and prove their guilt is very difficult. That is why the identification of the sources which are responsible for oil pollution seems to be one of the major environmental problems all over the world. However, thanks to efforts... view more... (2001-10-12)
"Nanosculpture" Could Enable New Types of Heat Pumps and Energy Converters
A new technique for growing single-crystal nanorods and controlling their shape using biomolecules could enable the development of smaller, more powerful heat pumps and devices that harvest electricity from heat. view more (2008-07-21)
Strengthening Fluids With Nanoparticles
Researchers at Rensselaer Polytechnic Institute have demonstrated that liquids embedded with nanoparticles show enhanced performance and stability when exposed to electric fields. The finding could lead to new types of miniature camera lenses, cell phone displays, and other microscale fluidic devices. view more (2008-02-20)
'Cooper pairs' can be found in insulators as well superconductors
Nearly a century ago, Dutch physicist Kamerlingh Onnes discovered that some metals transform into perfect electrical conductors when cooled to temperatures near absolute zero. Once started, their currents of electrons can flow perpetually. view more (2007-11-26)
Beyond the looking glass
While the researchers can't promise delivery to a parallel universe or a school for wizards, books like Pullman's Dark Materials and JK Rowling's Harry Potter are steps closer to reality now that researchers in China have created the first tunable electromagnetic gateway. view more (2009-08-13)
Is it effective of low-dose furazolidone-based quadruple regimens for H pylori infection?
H pylori infection was associated with many upper gastrointestinal diseases. The prevalence of H pylori resistant to antibiotics was increased with the spreading of H pylori eradication. view more (2009-02-23)
Princeton scientists discover exotic quantum state of matter
A team of scientists from Princeton University has found that one of the most intriguing phenomena in condensed-matter physics -- known as the quantum Hall effect -- can occur in nature in a way that no one has ever before seen. view more (2008-04-25)
Quantum dance: Discovery led by Princeton researchers could revolutionize computing
An international team of scientists, led by a Princeton University group, has observed an exciting and strange behavior in electrons' spin within a new material that could be harnessed to transform computing and electronics. view more (2009-02-19)
'Science:' Novel quantum effect directly observed and explained
An international research team has succeeded in gaining an in-depth insight into an unusual phenomenon, as reported in the current edition of the high-impact journal "Science". view more (2009-02-13)
Superconductors get a boost from pressure
Superconductors can convey more than 150 times more electricity than copper wires because they don't restrict electron movement, the essence of electricity. view more (2008-05-20)
Magnetic nanoparticles facilitate separations in 'one-pot' multi-step reactions
Using the unique properties of new nanometer-scale magnetic particles, researchers have for the first time separated for reuse two different catalysts from a multi-step chemical reaction done in a single vessel. view more (2006-03-15)
