Researcher solve one mystery of high-temperature superconductors
Unlike low-temperature superconductors, which are metals, high-temperature superconductors are insulators in their normal state. This has puzzled scientists, because half of the electron states are empty. view more (2005-11-29)
University of Pennsylvania Chemists Reinvent the Science and Industry of Making Plastics
Chemists at the University of Pennsylvania have created a new process for free radical polymerization, the chemical reaction responsible for creating an enormous array of everyday plastic products, from Styrofoam cups to PVC tubing to car parts. view more (2006-10-13)
UD researchers put 'spin' in silicon, advance new age of electronics
Electrical engineers from the University of Delaware and Cambridge NanoTech have demonstrated for the first time how the spin properties of electrons in silicon--the world's most dominant semiconductor, used in electronics ranging from computers to cell phones--can be measured and controlled. view more (2007-05-21)
Brookhaven lab scientists stabilize platinum electrocatalysts for use in fuel cells
Platinum is the most efficient electrocatalyst for accelerating chemical reactions in fuel cells for electric vehicles. In reactions during the stop-and-go driving of an electric car, however, the platinum dissolves, which reduces its efficiency as a catalyst. This is a major impediment for vehicle-application of fuel cells. view more (2007-01-15)
Einstein's magnetic effect is measured on microscale
A gyromagnetic effect discovered by Albert Einstein and Dutch physicist Wander Johannes de Haas-the rotation of an object caused by a change in magnetization-has been measured at micrometer-scale dimensions for the first time at the National Institute of Standards and Technology (NIST). view more (2006-10-02)
Researchers think pink to produce 'green' solar energy
When it comes to producing earth-friendly solar energy, pink may be the new green, according to Ohio State University researchers. Scientists here have developed new dye-sensitized solar cells, that get their pink color from a mixture of red dye and white metal oxide powder in materials that capture light. view more (2007-07-31)
Researchers explain odd oxygen bonding under pressure
Oxygen, the third most abundant element in the cosmos and essential to life on Earth, changes its forms dramatically under pressure transforming to a solid with spectacular colors. Eventually it becomes metallic and a superconductor. view more (2008-08-05)
Toward plastic spin transistors
University of Utah physicists successfully controlled an electrical current using the "spin" within electrons - a step toward building an organic "spin transistor": a plastic semiconductor switch for future ultrafast computers and electronics. view more (2008-08-18)
Hidden structure revealed in characteristics of transistor laser
The transistor laser, invented by scientists at the University of Illinois at Urbana-Champaign, has been full of surprises. view more (2006-04-06)
High-temperature superconductors: magnetic glue may be the clue
Striking pictures of magnetic waves inside advanced ceramics may be the clue to understanding how they can transmit electricity without losing energy, according to results obtained by two teams of scientists using the UK's world-leading ISIS neutron source in Oxfordshire and published this week in the journal Nature. The ceramics, known as... view more... (2004-06-02)
First Direct Observations of Spinons and Holons
Working at the Advanced Light Source (ALS) of the U.S. Department of Energy's Lawrence Berkeley National Laboratory, a team of researchers has observed the theoretical prediction of electron "spin-charge separation" in a one-dimensional solid. view more (2006-07-17)
Noise measurement may boost cell phone performance
Researchers at the National Institute of Standards and Technology (NIST) and industry collaborators have developed improved methods for accurately measuring very faint thermal "noise"—caused by random motion of electrons—in electronic circuits. view more (2006-06-28)
A new understanding of crystal structure of actinide metals
Researchers have a better understanding of how the crystal structure of some metals becomes stable through magnetism. Magnetic stabilization of the crystal structures of metals is rare. In some metals, such as manganese, iron, and cobalt, the magnetic interaction energy is large enough to influence the crystal structure. view more (2007-06-07)
A young pulsar shows its hand
A small, dense object only twelve miles in diameter is responsible for this beautiful X-ray nebula that spans 150 light years. view more (2009-04-06)
From graphene to graphane, now the possibilities are endless
Ever since graphene was discovered in 2004, this one-atom thick, super strong, carbon-based electrical conductor has been billed as a "wonder material" that some physicists think could one day replace silicon in computer chips. view more (2009-07-31)
From Europa to the lab, a new recipe for oxygen on icy moons
A new Pacific Northwest National Laboratory study offers the most detailed picture to date on how oxygen can be made in frigid reaches far from Earth. view more (2006-03-28)
Nano-signals get a boost from magnetic spin waves
Researchers have figured out how nanoscale microwave transmitters gain greater signal power than the sum of their parts-a finding that will help in the design of nano-oscillator arrays for possible use as transmitters and receivers in cell phones, radar systems, or computer chips. view more (2006-09-01)
'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)
Researchers at UC-Santa Barbara have built the world's first mode-locked silicon evanescent laser
Researchers at UC Santa Barbara have announced they have built the world's first mode-locked silicon evanescent laser, a significant step toward combining lasers and other key optical components with the existing electronic capabilities in silicon. view more (2007-08-22)
An aerial for light
Austrian physicists report unusual light-metal interaction A team under Professor Franz Aussenegg at the University of Graz in Austria is looking into unusual interactions between light and submicroscopic metal particles. The physicists' findings represent a major advance towards the development of improved data storage media and optical sensors.... view more... (2003-02-17)
