A new plastic made from CO2 and butadiene has been synthesized by Kyoko Nozaki and her research group at the University of Tokyo (Tokyo, Japan; www.chembio.t.u-tokyo.ac.jp/labs/nozaki). Although butadiene is already produced on a large scale for making synthetic rubber, it has previously been impossible to copolymerize CO2 and butadiene in a single-step reaction, because the...

Scientists from the A*STAR (Agency for Science, Technology and Research) Institute for Chemical and Engineering Sciences (Singapore; www.a-star.edu.sg) have shown that a copper catalyst can incorporate CO2 into organic molecules under mild conditions, opening the way to an inexpensive, nontoxic source of carbon for the synthesis of products such as plastics and pharmaceuticals. Normally, a lot of energy is...

North American production of crude oil, driven by a rapid increase in output of “tight oil” from U.S. shale deposits like Bakken and Eagle Ford, is surging. In many, but not all areas, petroleum refiners are incorporating an increasing amount of this cost-advantaged feedstock into their crude-oil-processing slates to capitalize on its discounted price, which is partly a result of a lack of...

A newly developed proprietary terpolymer from GE Water and Process Technologies (Trevose, Pa.; www.gewater.com) has been shown to provide improved scale control on heat-transfer surfaces in low- to intermediate- (up to 900 psig) pressure-steam boilers. Deposit formation on heat-transfer and steam-generating surfaces can result in reduced boiler efficiency and tube failures. Known as Solus AP, the GE...

Lithium is an element of growing importance for the production of batteries and nuclear fuels. Because Japan relies completely on imports of this material, with the majority coming from South America, the country is looking for alternative sources for this element. The answer may be in the island-nation’s own “backyard” — namely, seawater. A promising, “revolutionary”...
