Silk's secrets revealed

Silk's secrets revealed

Silks are among the toughest materials known, stronger and less brittle, pound for pound, than steel. Now scientists at MIT have unraveled some of their deepest secrets in research that could lead the way to the creation of synthetic materials that duplicate, or even exceed, the extraordinary properties of natural silk.

Organic catalysts could greatly ease polymer recycling, reuse

Scientists from IBM and Stanford University have recent detailed polymer discoveries that could lead to the development of new types of biodegradable, biocompatible plastics. The result of a multi-year research effort, the breakthrough is based on organocatalysis, specifically oxide-based catalysts that show activities rivaling the most active metal-based catalysts. Harnessing this activity could enable us to significantly increase the ability to recycle and reuse PET.

Creating a graphene hybrid

Rice Univ. researchers have found a way to stitch graphene and hexagonal boron nitride (h-BN) into a two-dimensional quilt that offers new paths of exploration for materials scientists.

Turning chemical manufacturing green

A new nanotech catalyst developed by McGill Univ. chemists offers industry an opportunity to reduce the use of expensive and toxic heavy metals. Although chemists have long been aware of the ecological and economic impact of traditional chemical catalysts and do attempt to reuse their materials, it is generally difficult to separate the catalyzing chemicals from the finished product. The team's discovery does away with this chemical process altogether.

Surface science goes inorganic

A collaboration between researchers at Northwestern Univ.'s Center for Catalysis and scientists at Oxford University has produced a new approach for understanding surfaces, particularly metal oxide surfaces, widely used in industry as supports for catalysts.

Aerogel material absorbs oil spills

An ultra-lightweight sponge made of clay and a bit of high-grade plastic draws oil out of contaminated water but leaves the water behind.

3-D scaffold provides biodegradable structure for stem cell growth

3-D scaffold provides biodegradable structure for stem cell growth

Materials scientists at the Univ. of Washington have built a three-dimensional scaffold out of a natural material that mimics the binding sites for stem cells, allowing the cells to reproduce on a clean, biodegradable structure. Results show that human embryonic stem cells grow and multiply readily on the structure.

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.

Venus flytrap for nuclear waste

Not every object is food to a Venus flytrap. Like the carnivorous plant, a new material developed at Northwestern Univ. permanently traps only its desired prey, the radioactive ion cesium, and not other harmless ions like sodium.

Hydrogen: A new superconductor?

Physicists have long wondered whether hydrogen could be transformed into a metal and possibly even a superconductor. High-pressure researchers have now modeled three hydrogen-dense metal alloys and found there are pressure and temperature trends associated with the superconducting state—a huge boost in the understanding of how this abundant material could be harnessed.

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.
