Study of the corrosive effects of water
As is known, corrosion is defined as the destruction of a material under chemical or electrochemical action by its surrounding environment. The reactions and transformations involved in this corrosion are due to the thermodynamic instability in the materials of which the surrounding environment is made up, giving rise to products with properties... view more...

Metal homeostasis research in plants will lead to nutrient-rich food and higher yielding crops
Deficiencies of micronutrients such as Iron and Zinc commonly limit plant growth and crop yields. Dartmouth Professor Mary Lou Guerinot is conducting research to better understand the mechanisms of micronutrient uptake, distribution and regulation. view more (2006-08-07)
A new hope for heavy metal contaminated soils
In the 1980s scientists began laboratory studies on metal hyperaccumulator plants, i.e. plants which accumulate exceptionally high concentrations of heavy metals in their above-ground biomass. This coincided with the recognition that a number of serious human diseases are the result of disruptions in metal homeostasis, for example Menke's disease,... view more... (2003-12-05)
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)
Nano-cages 'fill up' with hydrogen
A "cagey" strategy to stack more hydrogen in nanoscale scaffoldings made of zinc-based boxes may yield a viable approach to storing hydrogen and, ultimately, replacing fossil fuels in future automobiles, according to new results from National Institute of Standards and Technology (NIST) researchers. view more (2005-12-02)
Nitrous gases and zinc in the crosshairs
The Senate Commission for the Investigation of Health Hazards of Chemical Compounds in the Work Area established by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) has issued the MAK and BAT Values List for 2009. This year's list contains 62 changes and new entries. view more (2009-07-29)
Nanogenerators convert mechanical energy to electricity for self-powered devices
Researchers have developed a new technique for powering nanometer-scale devices without the need for bulky energy sources such as batteries. view more (2006-04-14)
New clues to how sex evolves
Sex is a boon to evolution; it allows genetic material from parents to recombine, giving rise to a unique new genome. But how did sex itself evolve\\\ view more (2006-12-05)
Researchers think pink to produce 'green' solar energy
When it comes to producing earth-friendly solar energy, pink may be the new green, according to Ohio State University researchers. Scientists here have developed new dye-sensitized solar cells, that get their pink color from a mixture of red dye and white metal oxide powder in materials that capture light. view more (2007-07-31)
Gene signature may predict patient response to therapy for gastrointestinal stromal tumors
Researchers at Fox Chase Cancer Center uncovered a genetic pattern that may help predict how gastrointestinal stromal tumor (GIST) patients respond to the targeted therapy imatinib mesylate (Gleevec). view more (2009-05-15)
Long distance runners at risk of low bone density
Long distance running increases the risk of low bone density, shows research in the British Journal of Sports Medicine. Accepted wisdom is that running, as a weight bearing exercise, increases bone density and therefore reduces the risk of osteoporosis and bone fracture. view more (2003-01-24)
Nanohelix structure provides new building block for nanoscale piezoelectric devices
A previously-unknown zinc oxide nanostructure that resembles the helical configuration of DNA could provide engineers with a new building block for creating nanometer-scale sensors, transducers, resonators and other devices that rely on electromechanical coupling. view more (2005-09-09)
Remarkable new clothing may someday power your iPod
Nanotechnology researchers at the Georgia Institute of Technology are developing a shirt that harvests energy from the wearer's physical motion and converts it into electricity for powering small electronic devices worn by soldiers in the field, hikers and other users. view more (2008-02-14)
Printable batteries
In the past, it was necessary to race to the bank for every money transfer and every bank statement. Today, bank transactions can be easily carried out at home. Now where is that piece of paper again with the TAN numbers? In the future you can spare yourself the search for the number. view more (2009-07-06)
'Strained' quantum dots show new optical properties
Quantum dots, tiny luminescent particles made of semiconductors, hold promise for detecting and treating cancer earlier. However, if doctors were to use them in humans, quantum dots could have limitations related to their size and possible toxicity. view more (2008-12-08)
HIV treatments improve health, but nutritional issues remain
Despite the success of highly active antiretroviral treatment (HAART), people with HIV may still be at higher risk for nutritional deficiencies and abnormalities. view more (2006-12-26)
New fertilizer SRM can help control heavy metal content
A new reference material developed by the National Institute of Standards and Technology (NIST) can help the agriculture industry and state regulators monitor the concentrations of several potentially hazardous heavy metal contaminants in fertilizers. view more (2006-10-13)
Nanogenerator provides continuous power by harvesting energy from the environment
Researchers have demonstrated a prototype nanometer-scale generator that produces continuous direct-current electricity by harvesting mechanical energy from such environmental sources as ultrasonic waves, mechanical vibration or blood flow. view more (2007-04-06)
Snails snack on poison metals
SOILS tainted with heavy metals from industrial pollution and sewage sludge may poison organisms that live in the soil far more readily than thought. The finding raises fears that unexpectedly high levels of toxins are getting into the food chain. Contaminated soils are given hazard ratings that are based on the key assumption that organisms can... view more... (2002-12-18)
