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)

The secret to long life
What controls lifespan? An intriguing new twist is emerging from the work of Professor Heinz Osiewacz (Frankfurt) using a short-lived fungus. He has discovered that when there is a mutation in the gene, Grisea, that controls copper uptake into cells, the fungus can live 60% longer than their normal... view more (2001-04-04)

Chemists measure copper levels in zinc oxide nanowires
Chemists at the National Institute of Standards and Technology (NIST) have been the first to measure significant amounts of copper incorporated into zinc oxide (ZnO) nanowires during fabrication.   view more (2008-02-20)

Intake of dietary copper helps Alzheimer's patients
As one of the services for patients with Alzheimer's disease, the Department of Psychiatry at the Saarland University Medical Center offers participation in a clinical phase II trial. This clinical trial aims to elucidate a potential beneficial effect of copper orotate (an organic copper salt),... view more (2005-10-04)

Probing a rare material spin state at NIST
A team of international physicists that includes researchers from the National Institute of Standards and Technology (NIST) has found experimental evidence of a highly sought-after type of arrangement of atomic magnetic moments, or spins, in a series of materials.   view more (2007-09-17)

High-fat, copper-rich diets associated with increased rates of cognitive decline in older adults
Among older adults whose diets are high in saturated and trans fats, a high intake of copper may be associated with an accelerated rate of decline in thinking, learning and memory abilities.   view more (2006-08-15)

Cancer cells forming blood vessels send their copper to the edge
New information about a link between the growth of blood vessels critical to the spread of cancer and the copper in our bodies has been discovered by researchers from the U.S. Department of Energy's Argonne National Laboratory and the University of Chicago, using a beamline at the Advanced Photon... view more (2007-02-28)

The nanoworld of corrosion
The effect of corrosion has an impact on about 3% of the world's Gross Domestic Product. From a positive point of view, however, chemical attack of metal surfaces may result into surface nano-structures with very interesting technological applications such as catalysts and sensors.   view more (2006-02-10)

Unique porous copper structure enables new generation of military micro-detonators
Tiny copper structures with pores at both the nanometer and micron size scales could play a key role in the next generation of detonators used to improve the reliability, reduce the size and lower the cost of certain military munitions.   view more (2007-12-19)

Clemson chemists discover new way antioxidants fight debilitating diseases
Cancer, cardiovascular diseases, Parkinson's and Alzheimer's are often linked to DNA damage that occurs when metal ions in the body such as iron and copper produce reactive oxygen compounds that damage human cells.   view more (2007-08-20)

Copper nanowires grown by new process create long-lasting displays
A new low-temperature, catalyst-free technique for growing copper nanowires has been developed by researchers at the University of Illinois. The copper nanowires could serve as interconnects in electronic device fabrication and as electron emitters in a television-like, very thin flat-panel display... view more (2008-04-29)

Yale study: Not enough metals in earth to meet global demand
Researchers studying supplies of copper, zinc and other metals have determined that these finite resources, even if recycled, may not meet the needs of the global population forever, according to a study published in the Proceedings of the National Academy of Sciences.   view more (2006-01-26)

Model for the assembly of advanced, single-molecule-based electronic components developed at Pitt
Researchers based at the University of Pittsburgh have created the best method so far of assembling wire-like structures only a single molecule wide, a significant step in science's increasing attempts to reduce the circuitry size of electronic devices to the single molecule scale and provide... view more (2007-09-27)
