Possibly Major Materials Science Breakthrough: "Carbon Dioxide Super Scrubber?"

 Why do I think the next secular bull market will be based on some combination of 
materials science, advanced manufacturing and nanotechnology?...

That's me, quoting myself.
From the Christian Science Monitor:
Scientists have announced a potential breakthrough in developing a new material that removes carbon dioxide from the air. CO2 scrubbing could be a useful tool against global warming

Using cheap, readily available materials, a team of chemists has developed a new compound for drawing carbon dioxide out of the atmosphere.

The compound holds the potential to drive down the cost of capturing carbon, although it's too early to say by how much, the scientists say.

The results "add to the list of possible materials that can absorb CO2 from the air, and it potentially could be quite a good one," says Klaus Lackner, who heads the department of earth and environmental engineering at Columbia University in New York and was not part of the team formulating the material....MORE
Here's the paper, recently published in the Journal of the American Chemical Society:

Carbon Dioxide Capture from the Air Using a Polyamine Based Regenerable Solid Adsorbent

Abstract Image
Easy to prepare solid materials based on fumed silica impregnated with polyethylenimine (PEI) were found to be superior adsorbents for the capture of carbon dioxide directly from air. During the initial hours of the experiments, these adsorbents effectively scrubbed all the CO2 from the air despite its very low concentration. The effect of moisture on the adsorption characteristics and capacity was studied at room temperature. Regenerative ability was also determined in a short series of adsorption/desorption cycles.
That Olah fellow is a bit slower than the rest, he's encumbered by some hardware
