Spinach and nanodiamonds?

Popeye, the comic book hero, swears by it as do generations of parents who delight their children with spinach. Of course, today it is known that the vegetable is not quite as rich in iron as originally thought, but that ...

Team bolsters batteries with nanotubes

Researchers at the Energy Department's National Renewable Energy Laboratory (NREL) are turning to extremely tiny tubes and rods to boost power and durability in lithium-ion batteries, the energy sources for cell phones, laptops, ...

Marine bacterium sheds light on control of toxic metals

An ocean-dwelling bacterium has provided fresh insights into how cells protect themselves from the toxic effects of metal ions such as iron and copper, in research led by the University of East Anglia (UEA).

Zapping untreated water gets rid of more waterborne viruses

Using sophisticated microscopy and computational analysis, Texas A&M University researchers have now validated the merit of a water purification technology that uses electricity to remove and inactivate an assortment of waterborne ...

Aqueous iron interacts as strong as solid iron

German scientists have applied a new method -- "inverse Partial Fluorescence Yield" (iPFY) on micro-jet -- which will enable them to probe the electronic structure of liquids free of sample damages. The experiments are performed ...
