Toxicity of antimicrobial silver in products can be reduced

Chemists in Finland have made new polymer-stabilized silver nanoparticles that they say significantly reduce the exposure to silver encountered by those who use silver’s ability to neutralize microbial contaminants, for example in colloidal silver water filters. Though silver’s health benefits are well known, the long-term exposure effects of small amounts of the toxin are not entirely understood.

Synthetic gene-like crystals created for carbon dioxide capture

Synthetic gene-like crystals created for carbon dioxide capture

UCLA chemists report creating a synthetic "gene" that could capture heat-trapping carbon dioxide emissions, which contribute to global warming, rising sea levels, and the increased acidity of oceans.

Exploring environmental concerns of nanotechnology

As researchers around the world hasten to employ nanotechnology to improve production methods for applications that range from manufacturing materials to creating new pharmaceutical drugs, a separate but equally compelling challenge exists.

Next-generation solar cells on the horizon

Next-generation solar cells on the horizon

A Monash Univ.-led international research team has developed an innovative way to boost the output of the next generation of solar cells. Scientists at Monash Univ., in collaboration with other universities in Germany, have produced tandem dye-sensitised solar cells with a three-fold increase in energy conversion efficiency compared with previously reported tandem dye-sensitised solar cells.  

Producing plastic without the use of fossil fuels

A team of pioneering South Korean scientists have succeeded in producing the polymers used for everyday plastics through bioengineering, rather than through the use of fossil fuel based chemicals. This research may now allow for the production of environmentally conscious plastics.

Taking the lead out of piezoelectrics

Taking 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. A lead-free alternative to the current crop of piezoelectric materials has been identified by researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the Univ. of California (UC), Berkeley.

Dandelion’s natural latex now used for rubber production

Dandelion’s natural latex now used for rubber production

  About 30,000 everyday items are made using natural rubber, but rubber trees in Asia are less than ideal because they can cause allergic reactions and are also decline from fungal disease. The Russian dandelion, used previously in World War II to make rubber, has now been optimized to fill this role.

Plastics decompose faster in the sea, but release toxins

In the first study to look at what happens over the years to the billions of pounds of plastic waste floating in the world's oceans, scientists are reporting that plastics—reputed to be virtually indestructible—decompose with surprising speed and release potentially toxic substances into the water.

Dopant permeation tubes

Kin-Tek Laboratories, Inc. manufacturers dopant permeation tubes used in detection systems for trace concentrations of narcotics, explosives, chemical warfare agents (CWAs), and industrial airborne molecular contaminants (AMCs).

A new job for nanoparticles: tracing rock fractures

Scientists with the Stanford Geothermal Program say they have achieved a proof-of-concept in the use of tiny nanoparticles as tracers to characterize fractured rocks.

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.
