Testimony: Mastery of rare earth elements vital to U.S. security

Testimony: Mastery of rare earth elements vital to U.S. security

Karl A. Gschneidner Jr., a senior metallurgist at Ames Lab, spoke before a House Subcommittee this week, cautioning them that rare-earth R&D in America is “virtually zero”. He went on to say that expertise in rare-earth alloying is crucial to economic performance and that the U.S. has given up much ground to other countries in this area.

Magnetic solders are a leap towards green alternatives

Magnetic solders are a leap towards green alternatives

Yale Univ. scientists have developed a magnetic solder that can be manipulated in three dimensions and selectively heated, and offers a more environmentally friendly alternative to today’s lead-based solders.

Producing multifunction nanodevices

A team led by Univ. of Wisconsin-Madison researchers has developed a new approach for creating powerful nanodevices, and their discoveries could pave the way for other researchers to begin more widespread development of these devices.

Physicist discovers odd, fluctuating magnetic waves

Physicist discovers odd, fluctuating magnetic waves

The uneasy relationship between magnetism and superconductivity is appreciated by physicists—magnetism both creates and destroys superconductors—but is poorly understood. New findings at Brown Univ. show strange sliding waves in superconductors at 10 Tesla. Never before seen by science, the waves may help quantum-level understanding.

Fractal patterns may be key to semiconductor magnetism

Fractal patterns may be key to semiconductor magnetism

A Princeton-led team of scientists has observed electrons in a semiconductor on the brink of the metal-insulator transition for the first time. Caught in the act, the electrons formed complex patterns resembling those seen in turbulent fluids, confirming some long-held predictions and providing new insights into how semiconductors can be turned into magnets.

Neutron studies support magnetism's role in superconductors

Neutron studies support magnetism's role in superconductors

Neutron scattering experiments performed at the Department of Energy's Oak Ridge National Laboratory give strong evidence that, if superconductivity is related to a material's magnetic properties, the same mechanisms are behind both copper-based high-temperature superconductors and the newly discovered iron-based superconductors.

Using magnetic toys as inspiration

Using magnetic toys as inspiration

Scientists have long studied how atoms and molecules structure themselves into intricate clusters. Unlocking the design secrets of Nature offers lessons in engineering artificial systems that could self-assemble into any desired form. A team from Harvard Univ. presented additional clues to how and why groups of atoms and molecules may favor less symmetrical and more complex, flexible geometric patterns.  

Levitating magnet brings space physics to fusion

Levitating magnet brings space physics to fusion

A new experiment that reproduces the magnetic fields of the Earth and other planets has yielded its first significant results. The findings confirm that its unique approach has some potential to be developed as a new way of creating a power-producing plant based on nuclear fusion—the process that generates the sun’s prodigious output of energy.

Magnet lab reclaims world record for highest-field resistive magnet

In late December, engineers at Florida State Univ. completed testing of a 36-T magnet, which just edges the 35-T record of the Grenoble High Magnetic Field Laboratory in France. The field, about 1,200 times stronger than a refrigerator magnet, is created used 20 MW.

New magnetic ferropaper material may make low-cost micromotors

New magnetic ferropaper material may make low-cost micromotors

Reasearchers at Purdue Univ. have created a magnetic "ferropaper" that might be used to make low-cost "micromotors" for surgical instruments, tiny tweezers to study cells and miniature speakers.

Much ado about next to nothing

Much ado about next to nothing

The recent review of the past 10 years of the National Nanotechnology Initiative--as presented by the President's Council of Advisors on Science and Technology--suggested the rise of nanomanufacturing as the near future of nanotechnology. But the actual proposed funding reflects a cautious approach, even about nanotech in general.

Lunar tires, space MRSA, and resonating microfluidics

Lunar tires, space MRSA, and resonating microfluidics

I typically attend the annual Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy each year in pursuit of specific coverage. This year, I sought out candidates for coverage in a vacuum technology article, and pulled together some instruments for a spectroscopy guide. But as busy as that kept me, it wasn’t all mass spectrometers and vacuum pumps on the show floor.

P2i showcases liquid repellent nano-coating for hearing aids
P2i showcases liquid repellent nano-coating for hearing aids

At the AudiologyNOW! 2010 show in San Diego next month, UK-based coatings company P2i will display their relatively new Aridion liquid-repellant nano-coating. Designed for exposure to humidity or sweat, the polymer layer is applied by a pulsed ion gas process that lower’s the hearing aid’s surface energy, coaxing water away from delicate components.

Submersible FlowCAM catches particle images and data in-situ and real-time

Fluid Imaging Technologies recently introduced its Submersible FlowCAM particle and cell imaging and analysis system at Ocean Sciences 2010 in Portland, Ore. The remote sensing platform can be used for continuous, unattended monitoring tethered to research vessels or autonomous submersibles.
