Because they are riddled with defects, bulk crystalline materials never achieve their ideal strength; nanocrystals, on the other hand, are so small there's no room for defects. ("Nano" is short for nanometer, a billionth of a meter.) Yet while nanocrystalline materials may approach ideal strength in their resistance to stress, most nanostructures have shown only a limited ability to withstand large internal strains before they fail. Overcoming this limitation could lead to great advances in...

By Patton, Jessica Rae UPDATES Chemical pollutants have cropped up in - and are threatening the very existence of - the populations of two distinctive predatory creatures (see "Intensive Condor Care," Currents, September/October 2007). As reported in the San Francisco Chronicle, "Studies of peregrine falcon eggs and chicks by state scientists reveal that the birds in San Francisco, Long Beach, Los Angeles and San Diego are ingesting the flame retardant called PBDEs, believed to leach out of...

By Kumar, Sunil Sharma, Vishal; Bhoyar, R V; Bhattacharyya, J K; Chakrabarti, Tapan ABSTRACT: The effect of heavy metals on the activities of earthworm species Eudrillus eugineae was studied during vermicomposting of municipal solid waste (MSW) spiked with heavy metals. The activities of earthworms, in terms of growth and biomass production and number of cocoons produced, were monitored periodically, and the concentration of heavy metals in earthworms and substrates was determined at...

By Liang, Yong-mei Jun, Ma; Liu, Wei ABSTRACT: A laboratory study demonstrated that ferrate pretreatment significantly enhanced lead and cadmium removal in alum coagulation, under the conditions of natural surface water. The enhancement of lead removal was approximately 21 to 37% by ferrate pretreatment at a dosage of 1 to 5 mg/L. The enhanced removal of cadmium by ferrate pretreatment at a dosage of 1 to 5 mg/L exceeded the removal by alum coagulation alone 2- to 12-fold. Cadmium is much...

GENEVA (Reuters) - Food experts on Friday set new international standards on maximum allowed levels of contaminants including lead and cadmium, as well as aflatoxins, so as to improve food safety, officials said. The standards, issued by the Codex Alimentarius Commission, are voluntary for countries, but apply to food consignments that move in international trade, they added. "The new standards adopted this week will thus go a long way to protecting human health, as they set out new,...

By Anthony J. Brown, MD NEW YORK (Reuters Health) - Women with the highest levels of cadmium in their urine have more than a two-fold higher risk of breast cancer than women with the lowest levels, according to a new study. However, further studies are needed to determine if these elevated levels are a cause or effect of breast cancer. Although cadmium, a heavy metal, has been classified as a probable cancer-causing substance by the US Environmental Protection Agency, until now no human...

Cadmium is a chemical element in the periodic table that has the symbol Cd and atomic number 48. A relatively rare, soft, bluish-white, toxic transition metal, cadmium occurs with zinc ores and is used largely in batteries. Notable characteristics Cadmium is a soft, malleable, ductile, bluish-white bivalent metal which can be easily cut with a knife. It is similar in many respects to zinc but lends itself to more complex compounds. The most common oxidation state of cadmium is +2,...

Silver is a chemical element in the periodic table that has the symbol Ag (from the traditional abbreviation from the Latin Argentum) and atomic number 47. A soft white lustrous transition metal, silver has the highest electrical and thermal conductivity of any metal and occurs in minerals and in free form. This metal is used in coins, jewelry, tableware, and photography. Notable characteristics Silver is a very ductile and malleable (slightly harder than gold) univalent coinage metal...

Zinc is a chemical element in the periodic table that has the symbol Zn and atomic number 30. Notable characteristics Zinc is a moderately reactive metal that will combine with oxygen and other non-metals, and will react with dilute acids to release hydrogen. The one common oxidation state of zinc is +2. Applications Zinc is the fourth most common metal in use, trailing only iron, aluminium, and copper in annual production. - Zinc is used to galvanize metals such as steel to...
