The reason some popular posts are tagged ‘no title’ is not because they have no title—they all do—but because the old Blogger embedded the title at the top of text, and the new software does not see that. You can see the titles in capitals at the start of each snippet. (It would be nice if Blogger introduced an upgrade program that could fix this little problem.)

A team of researchers with the U.S. Department of Energy's (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley has discovered an inexpensive metal catalyst that can effectively generate hydrogen gas from water.

The new proton-reduction catalyst is based on a molybdenum-oxo metal complex that is about one seventieth the cost of platinum, the most widely used metal catalyst for splitting the water molecule. The new catalyst does not need organic additives, and can operate in neutral water, even if it is dirty. It can also operate in sea water, the most abundant source of hydrogen on earth and a natural electrolyte. It is therefore ideal for renewable energy and sustainable chemistry.

The research team found that the complex catalyses the generation of hydrogen from neutral buffered water or even sea water with a turnover frequency of 2.4 moles of hydrogen per mole of catalyst per second.
