Cleaning up pollutants with sunlight
A cheap, harmless chemical and sunlight could provide an environmentally friendly way of destroying micro-pollutants in the environment. UK researchers are developing a new type of reactor to destroy persistent contaminants such as pesticides and pharmaceutical residues. The technology, which breaks down the polluting molecules into carbon... view more... (2002-10-23)
Researchers generate hydrogen without the carbon footprint
A greener, less expensive method to produce hydrogen for fuel may eventually be possible with the help of water, solar energy and nanotube diodes that use the entire spectrum of the sun's energy, according to Penn State researchers. view more (2008-07-16)
Novel approach estimates nanoparticles in environment
Without knowing how much of an industrial chemical is being produced, it is almost impossible for scientists to determine if it poses any threat to the environment or human health. view more (2009-05-21)
Toward a nanomedicine for brain cancer
In an advance toward better treatments for the most serious form of brain cancer, scientists in Illinois are reporting development of the first nanoparticles that seek out and destroy brain cancer cells without damaging nearby healthy cells. view more (2009-09-10)
Nanostructure boosts efficiency in energy transport
Overcoming a critical conductivity challenge to clean energy technologies, Boston College researchers have developed a titanium nanostructure that provides an expanded surface area and demonstrates significantly greater efficiency in the transport of electrons. view more (2009-03-03)
Titanium dioxide — It slices, it dices ...
Chemists from the National Institute of Standards and Technology (NIST) and Arizona State University have proposed an elegantly simple technique for cleaving proteins into convenient pieces for analysis. view more (2007-04-02)
Nanotech particles affect brain development in mice
Maternal exposure to nanoparticles of titanium dioxide (TiO2) affects the expression of genes related to the central nervous system in developing mice. view more (2009-07-29)
New titanium manufacturing process saves energy, helps protect troops
Whether for stopping cars or bullets, titanium is the material of choice, but it has always been too expensive for all but the most specialized applications. view more (2008-05-21)
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...

Titania nanotubes create potentially efficient solar cells
A solar cell, made of titania nanotubes and natural dye, may be the answer to making solar electricity production cost-effective, according to a Penn State researcher. view more (2006-02-08)
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)
Airbus A380 Mega-liner: Weight Savings by Titanium
The titanium parts implemented in the new Airbus A380 aircraft will constitute about 9 % by weight. The new mega-liner basic version is able to transport 555 passengers over a distance of 14.800 kilometres at a speed of Mach 0.85. Length and wingspan do not exceed 80m. Airbus aircraft has been using titanium alloys from the very beginning. Due to... view more... (2003-06-23)
Sunlight turns carbon dioxide to methane
Dual catalysts may be the key to efficiently turning carbon dioxide and water vapor into methane and other hydrocarbons using titania nanotubes and solar power, according to Penn State researchers. view more (2009-03-05)
'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...

Safety of combat military vehicles examined
A Queen's University Belfast academic is working on research that could help protect the lives of military based in Afghanistan. view more (2009-07-30)
Caltech scientists create titanium-based structural metallic-glass composites
Scientists from the California Institute of Technology (Caltech) have created a range of structural metallic-glass composites, based in titanium, that are lighter and less expensive than any the group had previously created, while still maintaining their toughness and ductility--the ability to be deformed without breaking. view more (2008-12-22)
Slippery customer: A greener antiwear additive for engine oils
Titanium, a protean element with applications from pigments to aerospace alloys, could get a new role as an environmentally friendly additive for automotive oil, thanks to work by materials scientists from Afton Chemical Corporation (Richmond, Va.) and the National Institute of Standards and Technology (NIST). view more (2008-07-24)
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)
Increased atmospheric carbon dioxide promotes algal growth
It is usually thought that unlike terrestrial plants, submerged plants like algae will not show any response to an increase of atmospheric carbon dioxide. This view may be biased by a neglect of the effects of the plants themselves on the water chemistry. In the June issue of Ecology Letters, Schippers, Lürling and Scheffer of the Wageningen... view more... (2004-05-13)
Ethylene suggested for hydrogen storage
Ethylene, a ho-hum material that is the building block of the most common plastic, might have an exciting future in storing hydrogen, the hoped-for transportation fuel of the future. view more (2006-12-11)
