Giant magnetocaloric materials could have large impact on the environment
Materials that change temperature in magnetic fields could lead to new refrigeration technologies that reduce the use of greenhouse gases, thanks to new research at the U.S. Department of Energy's Argonne National Laboratory and Ames National Laboratory. view more (2007-06-20)
Researchers study how ice melts in contact with soil
A team of scientists from the Max Planck Institute for Metals Research in Stuttgart (Germany) and the ESRF in France has studied how ice starts to melt at temperatures as low as - 17°C. This can occur when ice is in contact with SiO2, a material commonly found in soil. Below the melting temperature of ice, a layer much denser than 'regular'... view more... (2004-06-15)
Marsquake detection sensors will take search for water underground
Researchers at Imperial College London have just begun a 5-year project to design and build tiny earthquake measuring devices to go to Mars on the 2007 NetLander mission. Unlike the instruments on next year`s European Mars Express/Beagle II mission, the Marsquake sensors will be the first to look deep inside the planet. The internal structure of... view more...

DNA computing targets West Nile Virus, other deadly diseases
Researchers say that they have developed a DNA-based computer that could lead to faster, more accurate tests for diagnosing West Nile Virus and bird flu. view more (2006-10-17)
Working together to design robust silicon chips
Designers of high-speed silicon chips have often had to compromise on performance levels for their integrated circuit designs because of physical weaknesses appearing during design verification or even in production. view more (2009-11-13)
Carnegie Mellon U. chemists advance organic semiconductor processing
Any machinist will tell you that a little grease goes a long way toward making a tool work better. And that may soon hold true for plastic electronics as well. view more (2007-06-27)
Universe contains more calcium than expected
The universe contains one and a half times more calcium than previously assumed. This conclusion was drawn by astronomers of the SRON Netherlands Institute for Space Research, after observations with ESA's XMM-Newton X-ray observatory. view more (2007-02-07)
Measurements from the edge: magnetic properties of thin films
Materials researchers at the National Institute of Standards and Technology (NIST), together with colleagues from IBM and the Massachusetts Institute of Technology, have pushed the measurement of thin films to the edge-literally-to produce the first data on how the edges of metallic thin films contribute to their magnetic properties. view more (2007-10-01)
Changing thermal conductivity to improve the performance of Silicon Nitride components
Silicon nitride ceramics are important engineering materials due to their excellent properties such as fracture toughness, wear resistance and high temperature strength. view more (2006-01-17)
New battery technology helps stimulate nerves
With the help of new silicon-based compounds, scientists - and patients - are getting a significant new charge out of the tiny lithium batteries used in implantable devices to help treat nervous system and other disorders. view more (2005-10-05)
Solar Power Game-Changer: "Near Perfect" Absorption of Sunlight, From All Angles
Researchers at Rensselaer Polytechnic Institute have discovered and demonstrated a new method for overcoming two major hurdles facing solar energy. view more (2008-11-04)
Aluminum-oxide nanopore beats other materials for DNA analysis
Fast and affordable genome sequencing has moved a step closer with a new solid-state nanopore sensor being developed by researchers at the University of Illinois. view more (2009-06-03)
Diamond detectors - The Physics Congress 2002
Diamond has an extremely high resilience to radiation - three orders of magnitude higher than silicon - making it an ideal material for detectors that monitor radioactive emissions inside the hostile environments found in nuclear energy plants. But because of the high price of real diamond, synthetic diamond is needed. The latest developments in... view more... (2002-04-02)
Tension in the nanoworld
A joint team of researchers at CIC nanoGUNE (San Sebastian, Spain) and the Max Planck Institutes of Biochemistry and Plasma Physics (Munich, Germany) report the non-invasive and nanoscale resolved infrared mapping of strain fields in semiconductors. view more (2009-01-26)
Imaging Technology Restores 700-Year-Old Sacred Hindu Text
Scientists who worked on the Archimedes Palimpsest are using modern imaging technologies to digitally restore a 700-year-old palm-leaf manuscript containing the essence of Hindu philosophy. view more (2006-09-20)
Researchers make new electronics -- with a twist
They've made electronics that can bend. They've made electronics that can stretch. And now, they've reached the ultimate goal -- electronics that can be subjected to any complex deformation, including twisting. view more (2008-11-20)
Nanotube forests grown on silicon chips for future computers, electronics
Engineers have shown how to grow forests of tiny cylinders called carbon nanotubes onto the surfaces of computer chips to enhance the flow of heat at a critical point where the chips connect to cooling devices called heat sinks. view more (2007-10-02)
Sharply-tuned nanostrings work at room temperature
Using a fast, low-cost fabrication technique that allows inexpensive testing of a wide variety of materials, Cornell researchers have come up with nanoscale resonators - tiny vibrating strings - with the highest quality factor so far obtainable at room temperature for devices so small. view more (2006-07-17)
New technique could dramatically lower costs of DNA sequencing
Using computer simulations, researchers at the University of Illinois have demonstrated a strategy for sequencing DNA by driving the molecule back and forth through a nanopore capacitor in a semiconductor chip. The technique could lead to a device that would read human genomes quickly and affordably. view more (2007-12-13)
Small ... smaller ... smallest? ASU researchers create molecular diode
Recently, at Arizona State University's Biodesign Institute, N.J. Tao and collaborators have found a way to make a key electrical component on a phenomenally tiny scale. Their single-molecule diode is described in this week's online edition of Nature Chemistry. view more (2009-10-13)
