Newly discovered catalyst could lead to the low-cost production of clean methanol
An international research team has discovered a potentially clean, low-cost way to convert carbon dioxide into methanol, a key ingredient in the production of plastics, adhesives and solvents, and a promising fuel for transportation. Scientists from Stanford, SLAC and the Technical University of Denmark combined theory and experimentation to identify a new nickel-gallium catalyst that converts hydrogen and carbon dioxide into methanol with fewer side-products than the conventional catalyst.

A molecular ballet under the X-ray laser
An international team of researchers has used the world's most powerful X-ray laser to take snapshots of free molecules. The research team headed by Professor Jochen Küpper of the Hamburg Center for Free-Electron Laser Science choreographed a kind of molecular ballet in the X-ray beam. With this work, the researchers have cleared important hurdles on the way to X-ray images of individual molecules, as they explain in the scientific journal Physical Review Letters.

Advantages emerge in using nanostructured material when forging mechanical components
In his Ph.D. thesis, the Industrial Engineer Daniel Salcedo-Perez has studied the process to forge mechanical components using nanostructured material. Specifically, he has been able to produce matrices to forge a set of mechanical parts like cogs and gears. 'These functional nanostructured components have been produced free of faults, and this is something that had not been done previously,' he pointed out.

More dangerous chemicals in everyday life: Now experts warn against nanosilver
Endocrine disruptors are not the only worrying chemicals that ordinary consumers are exposed to in everyday life. Also nanoparticles of silver, found in dietary supplements, cosmetics and food packaging, now worry scientists. A new study from the University of Southern Denmark shows that nano-silver can penetrate our cells and cause damage.

Finding a few foes among billions of cellular friends
Beating cancer is all about early detection, and new research from the University of South Carolina is another step forward in catching the disease early. A team of chemists is reporting a new way to detect just a handful of lurking tumor cells, which can be outnumbered a billion to one in the bloodstream by healthy cells.

A cavity that you want
An international research team is developing an optical 'nanocavity' that boosts the amount of light that ultrathin semiconductors absorb. The advancement could lead to: more powerful photovoltaic cells; faster video cameras; and it could be useful for splitting water using energy from light, which could aid in the development of hydrogen fuel.

Now in 3-D: Video of virus-sized particle trying to enter cell
Tiny and swift, viruses are hard to capture on video. Now researchers at Princeton University have achieved an unprecedented look at a virus-like particle as it tries to break into and infect a cell. The technique they developed could help scientists learn more about how to deliver drugs via nanoparticles -- which are about the same size as viruses -- as well as how to prevent viral infection from occurring.

A fast and effective mechanism to combat an aggressive cancer
Professor Dan Peer of Tel Aviv University has developed a new strategy to tackle an aggressive subtype of ovarian cancer using a new nanoscale drug-delivery system designed to target specific cancer cells. He and his team have devised a cluster of nanoparticles called gagomers, made of fats and coated with a kind of polysugar. When filled with chemotherapy drugs, these clusters accumulate in tumors, producing dramatically therapeutic benefits.

Penn researchers 'design for failure' with model material
Researchers at the University of Pennsylvania have devised a method to study stress at the macro and micro scales at the same time, using a model system in which microscopic particles stand in for molecules. This method has allowed the researchers to demonstrate an unusual hybrid behavior in their model material: a reversible rearrangement of its particles that nevertheless has the characteristics of plastic deformation on the macroscale.

NIST microanalysis technique makes the most of small nanoparticle samples
Researchers from the National Institute of Standards and Technology and the Food and Drug Administration have demonstrated that they can make sensitive chemical analyses of minute samples of nanoparticles by, essentially, roasting them on top of a quartz crystal. The National Institute of Standards and Technology-developed technique, 'microscale thermogravimetric analysis,' holds promise for studying nanomaterials in biology and the environment, where sample sizes often are quite small and larger-scale analysis won't work.
