Scientists create improved CO2-absorbing crystals

Chemists in South Korea and the United States have improved the design of a type of artificial crystal, doubling the amount of carbon-dioxide they can absorb and store.
The new crystals are developed from an earlier crystal named MOF-177.
Called metal-organic frameworks (MOFs), the metallic crystals are porous, stable structures that can absorb and compress gases into very small spaces.
Scientists are hoping such materials can lead to cleaner energy and help capture heat-trapping carbon dioxide emissions before they reach the atmosphere and contribute to global warming, rising sea levels and ocean acidity.
Led by Omar Yaghi at UCLA’s California NanoSystems Institute, the team improved upon an earlier crystal named MOF-177 to produce two new versions -- MOF-200 and MOF-210 -- that can store twice the volume of gases.
"Porosity is a way to do a lot with little," said Yaghi, a chemistry and biochemistry professor, in a statement. "Instead of having only the outside surface of a particle, we drill small holes to dramatically increase the surface area."
The improved crystals were described in a paper published in the online edition of the journal Science.
Jaheon Kim, a chemistry professor at Seoul’s Soongsil University, helped design the MOF-210. He described one gram of MOFs as being about the size of four sugar tablets.
When flattened, each gram of these improved crystals could spread over 5,000 square meters, Yaghi said.
"If I take a gram of MOF-200 and unravel it, it will cover many football fields, and that is the space you have for gases to assemble," Yaghi said. "It’s like magic. Forty tons of MOFs is equal to the entire surface area of California."
In an email exchange with Reuters, Kim said he saw many uses for these crystals.
"They can be used for the short-term storage of CO2 (carbon dioxide) or fuel gas storage. I think it is practically possible," said Kim, adding that hydrogen could also be stored.
MOFs can be made from low-cost ingredients, such as zinc oxide, a common ingredient in sunscreen, and terephthalate, which is found in plastic soda bottles.

Global warming debunked: NASA report verifies carbon dioxide actually cools atmosphere
2013 05 22
Practically everything you have been told by the mainstream scientific community and the media about the alleged detriments of greenhouse gases, and particularly carbon dioxide, appears to be false, according to new data compiled by NASA’s Langley Research Center. As it turns out, all those atmospheric greenhouse gases that Al Gore and all the other global warming hoaxers have long ...
"Policy of multiculturalism in Europe has failed"
2013 05 22
The UK is experiencing a deficit of Caucasian people in the regions where the majority of the population is made up of immigrants and ethnic minorities. In the last 10 years more than 620 thousand white Brits left the capital of the UK, where Caucasians are now a minority making up only 45% of London’s population.
