Fair-Weather Clouds Hold Dirty Secret
New study reveals particles that seed small-scale clouds over OklahomaApril 2013
Results: Their fluffy appearance is deceiving. Fair-weather clouds have a darker side, according to scientists at Pacific Northwest National Laboratory. Fair-weather cumulus clouds contain an increasing amount of droplets formed around pollution particles. The new simulations, using data collected over Oklahoma, show how pollution from Oklahoma City increased the number of cloud droplets and reduced their size, affecting their sunlight absorbing, light scattering and cloud-seeding performance.

Controlling Proton Source Speeds Catalyst in Turning Electricity to Fuel
Nickel-based catalyst three times faster with adjustments to key acidApril 2013
Results: A new
catalyst is faster when it and its surrounding acid have the same proton
affinity or pKa, according to scientists at the Center
for Molecular Electrocatalysis, an Energy Frontier Research Center, at
Pacific Northwest National Laboratory. The catalyst drives turning electrons
and protons into a bond between two hydrogen atoms, storing the energy. Making
the catalyst faster is vital to designing technologies that can store electrons
created by wind turbines. The team's experimental and computational studies
focused on the acid that supplies the reaction's protons. When the acid and the
catalyst had the same pKa, the speed jumped from 2,400 and 27,000 hydrogen
molecules a second to 4,100 to 96,000.
