Schumacher to serve a two-year term on Executive Council Westmont, IL (PRWEB) February 20, 2012 McCrone Associates, Inc.’s senior research scientist, Elaine Schumacher, was elected to the Executive Council of the Microanalysis Society (MAS), and will serve a two-year term (2012-2014) as one of six directors. “I strongly support the ongoing efforts of MAS to define its role in the evolving world of microanalysis and its relationship with the Microscopy Society of America (MSA) and...

Affinity capture devices provide a platform for viewing cancer cells and other macromolecules in dynamic, life-sustaining liquid environments A photograph of a polar bear in captivity, no matter how sharp the resolution, can never reveal as much about behavior as footage of that polar bear in its natural habitat. The behavior of cells and molecules can prove even more elusive. Limitations in biomedical imaging technologies have hampered attempts to understand cellular and molecular...

A recently published article in Nature Chemistry by a research team at Stockholm University and the Polytechnic University of Valencia in Spain presents a new porous material that evinces unique properties for converting gasoline directly into diesel World fuel consumption is shifting more and more to diesel at the expense of gasoline. A recently published article in Nature Chemistry by a research team at Stockholm University and the Polytechnic University of Valencia in Spain presents a...

Atomic-level defects in graphene could be a path forward to smaller and faster electronic devices, according to a study led by researchers at the Department of Energy's Oak Ridge National Laboratory. With unique properties and potential applications in areas from electronics to biodevices, graphene, which consists of a single sheet of carbon atoms, has been hailed as a rising star in the materials world. Now, an ORNL study published in Nature Nanotechnology suggests that point defects,...

MIGDAL HAEMEK, Israel, January 5, 2012 /PRNewswire/ -- Camtek Ltd. (NASDAQ and TASE: CAMT) ("Camtek") announced today the first sale of its newly launched Xact200: the second generation of its revolutionary TEM/STEM sample preparation system for the Semiconductor industry. The purchase order was from a leading semiconductor company in Asia. Shrinking feature dimensions and advances in material complexity require a scale of analysis only possible through Transmission...

Not to pick up electrons, but tweezers made of electrons. A recent paper by researchers from the National Institute of Standards and Technology (NIST) and the University of Virginia (UVA) demonstrates that the beams produced by modern electron microscopes can be used not just to look at nanoscale objects, but to move them around, position them and perhaps even assemble them. Essentially, they say, the tool is an electron version of the laser "optical tweezers" that have become a standard...

Proteins caught 'in action' in intact cells using new electron microscopy technique Proteins are literally the movers and the shakers of the intracellular world. If DNA is the film director, then they are the actors. And much can be learned about cell function – and dysfunction – by watching proteins on the move. Until now, scientists have only been able to see this process indirectly. Now researchers at Vanderbilt University in Nashville, Tenn., have come up with a promising new...

A revolutionary conducting polymer enables the use of low-cost, high-energy silicon for the next generation of lithium-ion battery anodes Lithium-ion batteries are everywhere, in smart phones, laptops, an array of other consumer electronics, and the newest electric cars. Good as they are, they could be much better, especially when it comes to lowering the cost and extending the range of electric cars. To do that, batteries need to store a lot more energy. The anode is a critical...

Scientists can now look deeper into new materials to study their structure and behavior, thanks to work by an international group of researchers led by UC Davis and the Lawrence Berkeley National Laboratory and published Aug. 14 by the journal Nature Materials.The technique will enable more detailed study of new types of materials for use in electronics, energy production, chemistry and other applications.The technique, called angle-resolved photoemission, has been used since the 1970s to...

Berkeley Lab researchers observe structural transformations in single nanocrystalsWhile a movie about giant robots that undergo structural transformations is breaking box office records this summer, a scientific study about structural transformations within single nanocrystals is breaking new ground for the design of novel materials that will serve next-generation energy storage batteries and solar energy harvesting devices. Researchers at the U.S. Department of Energy (DOE)'s Lawrence...
