Sweet solution for chromium toxicity in industrial waste
Sugar shows promise in laboratory studies as a environmentally-friendly, economical alternative for reducing the toxicity of chromium waste products from the plating, mining and leather industries, according to a report by scientists in the United States and Mexico.
Chromium is normally converted to a less toxic form by treating industrial wastewater with large amounts of acid, which can foul lakes and rivers. In the current study, Bryan Bilyeu and colleagues showed that they could achieve a similar reduction in toxicity, up to 94 percent, by using natural sugars like fructose and sucrose.

Antidote for fuel cell poisoning: Gold and Silver Nanoparticles
With hydrogen emerging as the most promising energy sources for fuel cells, scientists in Illinois are reporting progress toward overcoming a major barrier to tapping hydrogens potential as a clean, abundant energy source.
Jose Rodriguez and colleagues explain that a major problem facing todays most promising fuel-cell technologies is that the same hydrogen-rich
