New Probe to Uncover Mechanisms Key to Fusion Reactor Walls

From Purdue University, University News Service, August 25, 2011:  "A new tool developed by nuclear engineers at Purdue University will be hitched to an expPurdue University erimental fusion reactor at Princeton University to learn precisely what happens when extremely hot plasmas touch and interact with the inner surface of the reactor.

The work is aimed at understanding plasma-wall interactions to help develop coatings or materials capable of withstanding the grueling conditions inside fusion reactors, known as tokamaks. The machines house a magnetic field to confine a donut-shaped plasma of deuterium, an isotope of hydrogen."  


The research "will provide information about how the coating materials evolve under plasma conditions and how the interaction correlates with changes in the plasma itself."

At the Forefront of Plasma-Surface Interaction 


From CNRS International Magazine (French National Center for Scientific Research), July 2011, p. 41, by Elaine Cobbe:  "Researchers from France and Luxembourg join forces to advance knowledge in plasma physics. European Associated Laboratory (LEA) LIPES, was created in January 2010.

For its initial four-year term (2010-2013), this "laboratory without walls" will work on studying the interactions between a plasma source a
CNRS Nitrogen Atmospheric Plasmand the topmost surface of various materials. The scientists will focus on "building" the top surface, from the single plasma species deposited on the material up to the complete monolayer. In this way, they hope to better understand the behavior of any isolated species as it touches the surface."

DOE Plans Shift in R&D Direction

From Chemical & Engineering News, Oct. 3, 2011, by Jeff Johnson:  ""The Department of Energymust reshuffle its research direction, according to an expert panel created to guide the agency's research needs over the next four years. In particular, the panel recommends a shift toward transportation-related R&D and away from aid to stationary sources of clean electricity.

Energy Secretary Steven Chu and Under Secretary for Science Steven E. Koonin rolled out the panel's report, the "Quadrennial Technology Review," on Sept. 27 at a briefing attended by a highly supportive and receptive audience of scientists. The first-of-its-kind review grew from recommendations of the President's Council of Advisors on Science & Technology, which urged DOE to better prioritize energy R&D.   The biggest proposed change in research direction, according to DOE, is a shift to electric vehicles."

Experiments Help Refine Thin-Film Solar Cells

From Oak Ridge National Laboratory, Sept. 1, 2011, by Deborah Counce: "Neutron scattering experiments conducted at Oak Ridge National Laboratory are helping solar cell makers obtain the hard data they need to refine their materials and manufacturing processes.

Recent studies of polymer-based solar cells at ORNL's Spallation Neutron Source and High Flux Isotope Reactor revealed important details about their molecular structure and showed that annealing (heat treating) the devices improves their power conversion efficiency. The experiments showed that annealing solar cells appropriately as they are fabricated improves their efficiency by more than 20 percent compared to films that aren't annealed. ORNL Thin Film Solar Cells


'We are trying to use mixtures of photoactive polymers to absorb light over a broad wavelength range to improve efficiency,' said principal investigator Thomas Russell of University of Massachusetts-Amherst. Haiyun Lu of U-Mass and Bulent Akgun of the NIST Center for Neutron Research and the University of Maryland are co-investigators. Studies such as this one are key to improving the performance of polymer-based solar cells so that they can compete in the marketplace."

Structural Efficiency Boost Heralds Third-Generation Solar Cells

From, October 11, 2011, by Navab Singh et al.: "The majority of solar cells are made of crystalline silicon-a material used for electronic circuits-that has a high production cost ($1.80 per peak watt). By contrast, low-grade silicon is a cheaper alternative that is widely used in thin-film solar cells. However, poor absorption of light and poor collection of resulting electric charge carriers result in a 50% reduction in efficiency compared to crystalline silicon.  

SPIE Poor reflection control (light not entering the film) and poor light trapping (light not being absorbed once inside) reduce light absorption. Defects inside the films also annihilate charge carriers before they can contribute to the electrical output, and so reduce the collection efficiency. We therefore added periodic vertical nanostructures to improve thin-film solar cells' reflection control, light trapping behavior, and collection efficiency."

Moving Away from Silicon Technology 


From, October 3, 2011: "Silicon, the conventional semiconductor used to build up electronics, is processed at very high temperature -over one thousand Celsius degrees- and it is difficult to recycle. With the aim of facilitating the sustainable and competitive manufacture of new displays with low-cost technology, scientists of the European project MULTIFLEOXIDES have developed new ceramic thin films containing amorphous or nano-structured oxides processed at low temperature to be used as transparent materials, conducting, semiconducting or insulating components in rigid and flexible electronic devices.  


'"The challenge is that we use zinc, which is a ceramic good-behaviour material, with gallium and indium and mix it within oxide to make new materials with electronic performances as good as silicon, something that was never tried before' says Rodrigo Martins, director of CEMOP (Center of Excellence in Microelectronics Optoelectronics and Processes) at the Portuguese University-Enterprise association UNINOVA (Institute for the Development of New Technologies), president of the European Materials Research Society and coordinator of the MULTIFLEOXIDES project."

Vacuum Coating Processing System for CIGS Cells Unveiled 


From, Oct. 18, 2011:  "Singulus Technologies AG (Kahl am Main, Germany) unveiled a new processing system for vacuum coating copper indium gallium diselenide (CIGS) thin-film solar photovoltaic (PV) cells.

The company also reported its first order for the system to an un-named customer. Singulus states that the main advantage of the system is that it can be used for the vertical vacuum-based coating of glass substrates.


The tool is a response to demand for tools that increase the efficiency of CIGS cells while cutting production costs. The company also notes that production of the tool gives it a new field of operations in the market for thin-film PV, in addition to its wet-processing and selenization systems for CIGS cells.

Polymer Characterization 'Tweezers' Turn Nobel Theory into Benchtop Tool 


From EurekAlert!, Oct. 19, 2011: "Researchers at UC Santa Barbara have developed a new and highly efficient way to characterize the structure of polymers at the nanoscale - effectively designing a routine analytical tool that could be used by industries that rely on polymer science to innovate new products, from drug delivery gels to renewable bio-materials.


Professor Omar Saleh and graduate student Andrew Dittmore of the UCSB Materials department have successfully measured the structure and other critical parameters of a long, string-like polymer molecule - polyethylene glycol, or PEG - by stretching it with an instrument called magnetic tweezers.


'We attach one end of the PEG molecule to a surface, and the other to a tiny magnetic bead, then pull on the bead by applying a magnetic field,' explained Saleh. 'The significance is that we're able to perform the elastic measurements - force vs. length measurement - to see aspects of polymer structure that are hard to see in any other way, and we can do it within minutes on a benchtop apparatus.'"

NASA's Webb Telescope Completes Mirror-Coating Milestone 


From, Sept. 13, 2011: "NASA's James Webb Space Telescope has reached a major milestone in its development. The mirrors that will fly aboard the telescope have completed the coating process at Quantum Coating Inc. in Moorestown, N.J.

The Webb telescope has 21 mirrors, with 18 mirror segments working together as one large 21.3-foot (6.5-meter) primary mirror. The mirror segments are made of beryllium, which was selected for its stiffness, light weight and stability at cryogenic temperatures. Bare beryllium is not very reflective of near-infrared light, so each mirror is coated with about 0.12 ounce of gold.  

Quantum Coatings
The Webb telescope is the world's next-generation space  observatory and successor to the Hubble Space Telescope.  The most powerful space telescope ever built, the Webb telescope will provide images of the first galaxies ever formed, and explore planets around distant stars. It is a joint project of NASA, the European Space Agency and the Canadian Space Agency."

Metamaterials: Photonic Sleight of Hand 


From Photonics Spectra, September 2011, by Marie Freebody:  "The field of metamaterials is barely 10 years old. First conceived in 2000 by Sir John Pendry at Imperial College London, metamaterials relied in the early days on advances in nanotechnology to build tiny structures such as metallic rings or wires smaller than the wavelength of light. These nanostructures modify the electromagnetic properties of the metamaterial, sometimes creating seemingly impossible optical effects.

In the optical regime, the visionary applications such as enhanced photovoltaic light collection, biosensing, perfect imaging, all-optical memories and, of course, invisibility cloaks are expected to have the highest and most wide-ranging impact.

Although the basic building blocks and enabled functionalities of these extraordinary media have (at optical wavelengths) been created and experimentally demonstrated, bringing optical metamaterials out of the laboratory remains a tall order, said professor Ortwin Hess, the Leverhulme Chair in Metamaterials at Imperial College London."

Microexplosion Reveals New Superdense Aluminum


From Advanced Materials & Processes, Oct. 2011, page 6: 
"A research team including Arturas Valionis of SLAC National Accelerator Laboratory, Stanford University, Calif., blasted tiny Advanced Materials and Processes bits of sapphire with a new table-top laser device that penetrates crystals and sets off microexplosions inside them, creating powerful shock waves that compress the surrounding material.  Under extreme conditions, warm dense matter forms, the state of matter between a solid and a plasma.  Because sapphire is a form of aluminum oxide, or alumina, researchers expected to find evidence of various phases of high-pressure alumina inside the get.  Instead, they observed minuscule amounts of a stable, highly compressed form of elemental body-centered-cubic aluminum."

Iron 'Veins' are Secret of Promising New Hydrogen Storage Material 


From NIST TechBeat, August 30, 2011:  "With a nod to biology, scientists at the National Institute of Standards and Technology (NIST) have a new approach to the problem of safely storing hydrogen in future fuel-cell-powered cars. Their idea: molecular scale "veins" of iron permeating grains of magnesium like a network of capillaries. The iron veins may transform magnesium from a promising candidate for hydrogen storage into a real-world winner.


Hydrogen has been touted as a clean and efficient alternative to gasoline, but it has one big drawback: the lack of a safe, fast way to store it onboard a vehicle. According to NIST materials scientist Leo Bendersky, iron-veined magnesium could overcome this hurdle. The combination of lightweight magnesium laced with iron could rapidly absorb-and just as importantly, rapidly release-sufficient quantities of hydrogen so that grains made from the two metals could form the fuel tank for hydrogen-powered vehicles."
