NOTE ON POPULAR POSTS

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.)

HYDROGEN FUEL-CELL VEHICLES NOW CLOSER

ScienceDaily outlines a paper published in
Science magazine that reveals a breakthrough in using ammonia borane to store hydrogen that will make it a far more attractive fuel for vehiclesby researchers at the Los Alamos National Laboratory describes a simple scheme that regenerates ammonia borane from a hydrogen-depleted 'spent fuel' form (called polyborazylene) back into a usable fuel via reactions in a single container. That 'one pot' method represents a significant step toward the practical use of hydrogen in vehicles by potentially reducing the expense and complexity of the recycling stage. Regeneration takes place in a sealed pressure-vessel in off-vehicle sites using hydrazine and liquid ammonia at 40 degrees Celsius. The researchers envision vehicles with interchangeable hydrogen storage tanks containing ammonia borane that are used then sent back to a factory for recharging.
