Salt Water System Could Generate Hydrogen

(PhysOrg.com) -- The idea of generating hydrogen from salt water has often been claimed to work effectively. However, the systems proposed so far generally require a much greater energy input than the energy they produce, ...

Solving a natural riddle of water filtration

For many engineers and scientists, nature is the world's greatest muse. They seek to better understand natural processes that have evolved over millions of years, mimic them in ways that can benefit society and sometimes ...

Atomic-scale capillaries block smallest ions, thanks to graphene

Researchers at The University of Manchester's National Graphene Institute in the UK have succeeded in making artificial channels just one atom in size for the first time. The new capillaries, which are very much like natural ...

New water-splitting catalyst found

(PhysOrg.com) -- Expanding on work published two years ago, MIT's Daniel Nocera and his associates have found yet another formulation, based on inexpensive and widely available materials, that can efficiently catalyze the ...

Gold solution for enhancing nanocrystal electrical conductance

In a development that holds much promise for the future of solar cells made from nanocrystals, and the use of solar energy to produce clean and renewable liquid transportation fuels, researchers with the U.S. Department of ...
