With a nod to biology, scientists at the National Institute of Standards and Technology (NIST) have a new approach to the problem of safely storing hydrogen in future fuel-cell-powered cars. Their idea: molecular scale "veins" of iron permeating grains of magnesium like a network of capillaries. The iron veins may transform magnesium from a promising candidate for hydrogen storage into a real-world winner. Hydrogen has been touted as a clean and efficient alternative to gasoline, but it...

HOUSTON, Aug. 3, 2011 /PRNewswire/ -- As children we're taught that our bodies need calcium to grow tall and healthy. As adults, we learn that calcium helps keep our bones strong and our minds sharp. By the time we reach our golden years, most of us will be taking dietary calcium supplements and consuming plenty of calcium foods under doctor's recommendation. The problem is some popular forms of calcium may actually cause the body more harm than good. "People have a false sense of security...
ORANGE, Calif., July 27, 2011 /PRNewswire/ -- A magnesium deficiency reduces the absorption and metabolism of calcium and prevents the proper amount of calcium being directed toward building stronger bones. According to Dr. Carolyn Dean, MD, ND, magnesium expert and Medical Director of the nonprofit Nutritional Magnesium Association (http://www.nutritionalmagnesium.org), the effectiveness and benefits of calcium with respect to bone health and the prevention of osteoporosis are greatly...

Aluminum (or aluminium) is a soft, lightweight, silvery metal. It is an element in the boron group on the periodic table of elements, with the symbol Al and atomic number 13. On the earth's crust, aluminum is the most abundant metal, and the third most abundant of all elements on the earth's crust, after oxygen and silicon. It accounts for 8% of the weight of the Earth's solid surface. Because aluminum is a highly reactive metal, it doesn't occur in nature in a pure form. Aluminum forms a...
Aurichalcite is a mineral, usually found as a secondary mineral in copper and zinc deposits. Its chemical formula is (Zn,Cu)5(CO3)2(OH)6. The name probably originates from the Greek oreichalchos meaning "mountain copper".
Cobalt is a chemical element in the periodic table that has the symbol Co and atomic number 27. Notable characteristics Cobalt is a hard ferromagnetic silver-white element. The Curie temperature is of 1388 K with 1.6~1.7 Bohr magnetons per atom. It is frequently associated with nickel, and both are characteristic ingredients of meteoric iron. Mammals require small amounts of cobalt salts. Cobalt-60, an artificially produced radioactive isotope of cobalt, is an important radioactive...
Copper is a chemical element in the periodic table that has the symbol Cu and atomic number 29. Notable characteristics Copper is a reddish-coloured metal, with a high electrical and thermal conductivity (among pure metals at room temperature, only silver has a higher electrical conductivity). Copper may well be the oldest metal in use, as copper artifacts dating to 8700 BC have been found. Besides being part of various ores, copper can be found in the metallic form (i.e. native copper)...
Manganese is a chemical element in the periodic table that has the symbol Mn and atomic number 25. Notable characteristics Manganese is a gray-white metal, resembling iron. It is a hard metal and is very brittle, fusible with difficulty, but easily oxidized. Manganese metal is ferromagnetic only after special treatment. The most common oxidation states of manganese are +2, +3, +4, +6 and +7, though oxidation states from +1 to +7 are observed. Mn2+ often competes with Mg2+ in...
