Scientists grow 'nanonets' able to snare added energy transfer
Using two abundant and relatively inexpensive elements, Boston College chemists have produced nanonets, a flexible webbing of nano-scale wires that multiplies surface area critical to improving the performance of the wires in electronics and energy applications. view more (2008-09-03)
'Hot' oxygen atoms on titanium dioxide motivated by more than just temperature
Like two ballroom dancers waltzing together, the two atoms of an oxygen molecule severed by a metal catalyst usually behave identically. But new research reveals that on a particular catalyst, split oxygen atoms act like a couple dancing the tango: one oxygen atom plants itself while the other shimmies away, probably with energy partially stolen... view more...

Researchers coat titanium with polymer to improve integration of joint replacements
Research at the Georgia Institute of Technology shows that coating a titanium implant with a new biologically inspired material enhances tissue healing, improves bone growth around the implant and strengthens the attachment and integration of the implant to the bone. view more (2008-07-02)
Problem: Implant Infection. Solution: Nanotech Surfaces
Orthopaedic implants help millions of Americans stay active. But these medical devices are prone to infection, forcing patients back to surgery for repair or replacement. Now, for the first time, a team of engineers has shown that zinc or titanium oxide nanosurfaces can reduce the presence of bacteria, a technique that can be applied to implants... view more...

Dancing 'adatoms' help chemists understand how water molecules split
Single oxygen atoms dancing on a metal oxide slab, glowing brighter here and dimmer there, have helped chemists better understand how water splits into oxygen and hydrogen. In the process, the scientists have visualized a chemical reaction that had previously only been talked about. The new work improves our understanding of the chemistry needed... view more...

Hydrogen tank lighter than battery
Dutch-sponsored researcher Robin Gremaud has shown that an alloy of the metals magnesium, titanium and nickel is excellent at absorbing hydrogen. view more (2008-11-05)
Nanowire coating for bone implants, stents
University of Arkansas researchers have found a simple, inexpensive way to create a nanowire coating on the surface of biocompatible titanium that can be used to create more effective surfaces for hip replacement, dental reconstruction and vascular stenting. view more (2007-08-28)
Jefferson Scientists Design Method to Fight Artificial Implant Infections with Antibiotics
Infections associated with inserting a medical device can be devastating, painful, and cause prolonged disability, costing tens of thousands of dollars. view more (2005-09-26)
Cardiac fibrillation of the climate
In the current issue of the Scientific Journal Nature Geoscience a group of Norwegian, Swiss and German geoscientists prove that before the set-in of the Holocene very rapid climate changes already existed. view more (2009-02-17)
Guggenheim Bilbao museum gleaming again
Originality and suitability of titanium sheets that cover the exterior of the building was highlighted, among other things, the day Guggenheim Bilbao museum was opened - October 1997. Titanium, apart from being spectacular, is a material that does not require special maintenance. It is a light material and has a great resistance against salt water... view more... (2001-07-10)
Electrons 'in limbo' seen for first time
Hrvoje Petek, University of Pittsburgh professor of physics and codirector of Pitt's Gertrude E. and John M. Petersen Institute of NanoScience and Engineering (PINSE), has published two papers in recent weeks that literally illuminate how electrons behave on various surfaces. view more (2006-03-15)
UCLA researchers solve decade-old mystery
Environmentally friendly hydrogen gas fueled vehicles can dramatically reduce greenhouse gas emissions and lessen the country's dependence on sources of fossil fuel. Though several hydrogen vehicles exist on the market today, there is still much room for improvement in the way that hydrogen is stored on-board the vehicle. view more (2008-02-27)
Laser processes promise better artificial joints, arterial stents
Researchers are developing technologies that use lasers to create arterial stents and longer-lasting medical implants that could be manufactured 10 times faster and also less expensively than is now possible. view more (2009-09-16)
Titanium human “spare parts”
Heart valves bred from a patient’s own cells would be a big progress. Meanwhile, surgeons have to make do with other methods and materials: tissue grafts, modified heart valves from human or animal donors. Valves made from artificial materials have the advantage of lasting longer. But they have the unfortunate drawback to intensify the... view more... (2002-09-09)
Colour effects inspired by instant soup
The shimmering colors of beetle and butterfly wings are not usually due to pigments. Instead, these and rainbow effects are produced by interference - as in opal gemstones, or an oil slick on a wet road. Layers of colorless substances, of a thickness that lies within the wavelength of visible light, cancel out certain parts of the spectrum. The... view more... (2002-09-20)
EU smart construction materials absorb and wash away pollution
A European consortium of private enterprises, research institutions and the European Commission's Joint Research Centre (JRC) is running a test programme for innovative construction materials set to help in the fight against air pollution. The "smart" construction materials (plaster, mortar, architectural concrete) and coatings are being... view more... (2004-03-04)
Fake diamonds help jet engines take the heat
Engineers are developing a technology to coat jet engine turbine blades with zirconium dioxide -- commonly called zirconia, the stuff of synthetic diamonds -- to combat high-temperature corrosion. The zirconia chemically converts sand and other corrosive particles that build up on the blade into a new, protective outer coating. In effect, the... view more... (2008-03-18)
Ancient diatoms lead to new technology for solar energy
Engineers at Oregon State University have discovered a way to use an ancient life form to create one of the newest technologies for solar energy, in systems that may be surprisingly simple to build compared to existing silicon-based solar cells. view more (2009-04-09)
Solar energy: Charged for the future
Once regarded as costly and impractical, solar technology is now poised to play a larger role in the future, thanks to new developments that could result in lower costs and improved efficiency. view more (2006-09-11)
NIST and partners identify tiny gold clusters as top-notch catalysts
For most of us, gold is only valuable if we possess it in large-sized pieces. However, the "bigger is better" rule isn't the case for those interested in exploiting gold's exceptional ability to catalyze a wide variety of chemical reactions, including the oxidation of poisonous carbon monoxide (CO) into harmless carbon dioxide at room... view more...
