U.S. chemists say they've developed a class of new porous materials that are very effective at purifying hydrogen by separating it from complex gas mixtures. Northwestern University Professor Mercouri Kanatzidis and postdoctoral researcher Gerasimos Armatas said their new materials exhibit excellent selectivity in separating hydrogen from carbon dioxide and methane. A more selective process means fewer cycles to produce pure hydrogen, increasing efficiency, said Kanatzidis. Our materials...

President Barack Obama's pursuit of energy independence promises to accelerate research and development for alternative energy sources -- solar, wind and geothermal power, biofuels, hydrogen and biomass, to name a few. For the hydrogen economy, one of the roadblocks to success is the hydrogen itself. Hydrogen needs to be purified before it can be used as fuel for fuel cells, but current methods are not very clean or efficient. Northwestern University chemist Mercouri G. Kanatzidis, together...

baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
