Catalysis discovery takes aim at NOx emissions
A discovery in molecular chemistry may help remove a barrier to widespread use of diesel and other fuel-efficient "lean burn" vehicle engines. Researchers at the Department of Energy's Pacific Northwest National Laboratory have recorded the first observations of how certain catalyst materials used in emission control devices are... view more...

Cornell researchers clone aluminum-tolerance gene in sorghum, promising boost to crop yields in developing world
When soils are too acidic, aluminum that is locked up in clay minerals dissolves into the soil as toxic, electrically charged particles called ions, making it hard for most plants to grow. In fact, aluminum toxicity in acidic soils limits crop production in as much as half the world's arable land, mostly in developing countries in Africa, Asia and... view more... (2007-08-28)
Tandem ions may lead the way to better atomic clocks
Physicists at the Commerce Department's National Institute of Standards and Technology (NIST) have used the natural oscillations of two different types of charged atoms, or ions, confined together in a single trap, to produce the "ticks" that may power a future atomic clock. view more (2005-07-29)
Novel processing of Yttrium Aluminum Garnet promises improved raw materials for lasers
Yttrium Aluminum Garnet (YAG) is an important material used in the production of laser systems, for coating electronic devices, for tubes of cathodic rays and recently it has been considered as a suitable material for structural applications at high temperatures. view more (2005-10-19)
Journal of Alzheimer's Disease is devoted to metal ions and neurodegenerative diseases
The recent issue of the Journal of Alzheimer's Disease (Volume 8, Issue 2) published by IOS Press is devoted to "Metal Ions and Neurodegenerative Diseases" and presents a collection of important papers dedicated to uncovering the role of various metals in human neurophysiology and neurodegenerative disorders. view more (2006-01-13)
Super sensitive gas detector goes down the nanotubes
When cells are under stress, they blow off steam by releasing minute amounts of nitrogen oxides and other toxic gases. view more (2009-01-14)
Paying peanuts for clean water
Peanut husks, one of the biggest food industry waste products, could be used to extract environmentally damaging copper ions from waste water, according to researchers in Turkey. view more (2007-11-08)
New efficiency record for solar cells
The efficiency improvement is achieved by the use of an ultra-thin aluminum oxide layer at the front of the cell, and it brings a breakthrough in the use of solar energy a step closer. view more (2008-05-15)
Researchers demonstrate reversible generation of a high capacity hydrogen storage material
Researchers at the U.S. Department of Energy's Savannah River National Laboratory have created a reversible route to generate aluminum hydride, a high capacity hydrogen storage material. view more (2009-07-07)
Under pressure, atoms make unlikely alloys
Ever since the Bronze Age, humans have experimented with combining different metals to create alloys with properties superior to either metal alone. view more (2009-03-11)
NIST demonstrates better memory with quantum computer bits
Physicists at the National Institute of Standards and Technology (NIST) have used charged atoms (ions) to demonstrate a quantum physics version of computer memory lasting longer than 10 seconds-more than 100,000 times longer than in previous experiments on the same ions. view more (2005-08-11)
Aluminum-oxide nanopore beats other materials for DNA analysis
Fast and affordable genome sequencing has moved a step closer with a new solid-state nanopore sensor being developed by researchers at the University of Illinois. view more (2009-06-03)
New plasma transistor could create sharper displays
By integrating a solid-state electron emitter and a microcavity plasma device, researchers at the University of Illinois have created a plasma transistor that could be used to make lighter, less expensive and higher resolution flat-panel displays. view more (2009-02-05)
Compound removes radioactive material from power plant waste
Strontium 90 is a common radioactive by-product of fission in nuclear power plants. When extracted from the reactor along with other isotopes, a mixture is created made up of the radioactive material and inert ions like sodium and calcium. view more (2008-03-13)
Metal hazard from table wines
Potentially hazardous levels of metal ions are present in many commercially available wines. An analysis of reported levels of metals in wines from sixteen different countries, published in the open access Chemistry Central Journal, found that only those from Argentina, Brazil and Italy did not pose a potential health risk owing to metals. view more (2008-10-30)
Scientists discover how nanocluster contaminants increase risk of spreading
For almost half a century, scientists have struggled with plutonium contamination spreading further in groundwater than expected, increasing the risk of sickness in humans and animals. view more (2008-04-18)
Topical Papers in Biochemical Journal - Selective determination of mitochandrial chelatable iron in viable cells with a new fluorescent sensor
This paper by Petrat and colleagues marks an important advance in our understanding of the regulation of iron in the human body. Real-time changes in the concentration of the ionized form of iron (Fe2+) can now be monitored within the mitochondria of living cells for the first time, thanks to the technique described in this article. For some... view more... (2002-02-08)
Lighter gas reduces damage to optics in extreme ultraviolet lithography
Researchers at the University of Illinois have discovered a way to generate light and reduce damage in a leading candidate for next-generation microelectronics lithography. The technique could help pack more power into smaller computer chips. view more (2007-09-13)
New aluminum-rich alloy produces hydrogen on-demand for large-scale uses
Purdue University engineers have developed a new aluminum-rich alloy that produces hydrogen by splitting water and is economically competitive with conventional fuels for transportation and power generation. view more (2008-02-20)
A Penny for Your Prions
North Carolina State University researchers have discovered a link between copper and the normal functioning of prion proteins, which are associated with transmissible spongiform encephalopathy diseases such as Cruetzfeldt-Jakob in humans or "mad cow" disease in cattle. view more (2009-06-26)
