Reversible doping: Hydrogen flips switch on vanadium oxide
Rice University physicists find reversible way to alter VO2's unique electronic about-face
05-25-2012
If you are not a condensed matter physicist, vanadium oxide (VO2) may be the coolest material you've never heard of. It's a metal. It's an insulator. It's a window coating and an optical switch. And thanks to a new study by physicists at Rice University, scientists have a new way to ...
BGU researchers successfully test an engineered oasis for solar desalination and arid land agriculture
05-24-2012
Ben-Gurion University of the Negev and Central and Northern Arava R&D researchers presented the successful application of solar-powered membrane desalination to arid agriculture at the Conference on Desalination for the Environment in Barcelona late last month.Dr. Andrea Ghermandi of the ...
Study shows availability of hydrogen controls chemical structure of graphene oxide
Metastable material
05-24-2012
A new study shows that the availability of hydrogen plays a significant role in determining the chemical and structural makeup of graphene oxide, a material that has potential uses in nano-electronics, nano-electromechanical systems, sensing, composites, optics, catalysis and energy ...
Hall effect at the speed of light: How can you demonstrate relativistic effects with your mobile phone?
05-23-2012
The relativistic Hall effect describing objects rotating at speeds comparable with the speed of light has now been reported. The work by Konstantin Bliokh and Franco Nori at RIKEN in Japan, NAS in Ukraine, and the University of Michigan in the US sheds light on aspects of fundamental physics, ...
BASF and Volkswagen jointly sponsor international “Science Award Electrochemistry”
Prize money of €50,000
05-23-2012
BASF and Volkswagen are launching an international initiative to promote research in the electrochemistry field. The “Science Award Electrochemistry” is intended to promote outstanding scientific and engineering achievements and provide impetus for the development of high-performance energy ...
Functional coatings from the plasma nozzle
05-23-2012
When manufacturing products, the coating technology is a key innovation driver for almost all areas of daily life – for example, for making scratch-proof displays for smart phones or anti-bacterial surfaces in refrigerators. Other coatings protect components from corrosion or aging, for ...
From lemons to lemonade: Using carbon dioxide to make carbon nitride
Exothermic reaction also yields lithium cyanamide, a precursor to fertilizers
05-23-2012
A materials scientist at Michigan Technological University has discovered a chemical reaction that not only eats up the greenhouse gas carbon dioxide, it also creates something useful. And, by the way, it releases energy. Making carbon-based products from CO2 is nothing new, but carbon ...
Production of chemicals without petroleum
Systems metabolic engineering of microorganisms allows efficient production of natural and non-natural chemicals from renewable non-food biomass
05-22-2012
In our everyday life, we use gasoline, diesel, plastics, rubbers, and numerous chemicals that are derived from fossil oil through petrochemical refinery processes. However, this is not sustainable due to the limited nature of fossil resources. Furthermore, our world is facing problems ...
Using graphene, scientists develop a less toxic way to rust-proof steel
Nontoxic composite under development at UB could replace commonly used toxic coatings
05-22-2012
University at Buffalo researchers are making significant progress on rust-proofing steel using a graphene-based composite that could serve as a nontoxic alternative to coatings that contain hexavalent chromium, a probable carcinogen. In the scientists' first experiments, pieces of steel ...
Improved lubrication without oil
05-22-2012
Metalworking plays a key role in industry. Drilling, milling, turning and grinding operations all use lubricants to prevent work pieces and tools from overheating and from excess wear. Standard lubricants today are based on mineral oil. This has drawbacks: fossil mineral oils come from finite ...
