Filtering carbon dioxide, a greenhouse gas, from factory smokestacks is a necessary, but expensive part of many manufacturing processes. However, a collaborative research team from the National Institute of Standards and Technology (NIST) and the University of Delaware has gathered new insight into the performance of a material called a zeolite that may stop carbon dioxide in its tracks far more efficiently than current scrubbers do. Zeolites are highly porous rocks–think of a sponge...

Possible applications in chemistry and industry Zeolites are porous materials with perfectly regular pores and high surface area that can act as molecular sieves. This property has led to important applications including the purification of air or water such as the contaminated seawater around Fukushima. Zeolites are used as catalysts — all gasoline is now made with zeolites — and for the separation and adsorption of numerous substances. While more than 200 zeolites are known...

Researchers studying how fluids travel through nanoscale channels were surprised to discover that the fluids don't flow equally well in all directions. Contrary to the behavior in the macroscale world, the researchers discovered that methyl alcohol, when it was placed in a network of nanoscale channels in a mineral known as a zeolite, diffused 1,000 times faster in one direction than another. This is the first known evidence of such highly unequal diffusion of molecules in a nanoporous...

Breakthrough culminates a decade´s worth of research A University of Minnesota team of researchers has overcome a major hurdle in the quest to design a specialized type of molecular sieve that could make the production of gasoline, plastics and various chemicals more cost effective and energy efficient. The breakthrough research, led by chemical engineering and materials science professor Michael Tsapatsis in the university's College of Science and Engineering, is published in the...

A combination of forest byproducts and crustacean shells may be the key to removing radioactive materials from drinking water, researchers from North Carolina State University have found. "As we're currently seeing in Japan, one of the major health risks posed by nuclear accidents is radioactive iodide that dissolves into drinking water. Because it is chemically identical to non-radioactive iodide, the human body cannot distinguish it "“ which is what allows it to accumulate in the...

Rice University team creates database of 2.6 million varieties of molecular sieves Some people collect stamps and coins, but when it comes to sheer utility, few collections rival the usefulness of Rice University researcher Michael Deem's collection of 2.6 million zeolite structures. Zeolites are materials -- including some natural minerals -- that act as molecular sieves, thanks to a Swiss-cheese-like arrangement of pores that can sort, filter, trap and chemically process everything from...

ORLANDO, Fla., Dec. 5, 2010 /PRNewswire-FirstCall/ -- Amgen Inc. (Nasdaq: AMGN) today announced the final results from a 5-year open-label extension study investigating the long-term efficacy and safety of Nplate® (romiplostim) in adult chronic immune (idiopathic) thrombocytopenic purpura (ITP). Chronic ITP is a serious autoimmune disorder characterized by low platelet counts in the blood (thrombocytopenia), which can lead to serious bleeding events. The complete data,...

Study first to show that drug reduces risk of dangerous bleeding, need for spleen removal A new study finds that an FDA-approved drug to treat the rare autoimmune disorder immune thromobocytopenia (ITP) is more effective than earlier medical therapies in helping patients avoid surgical treatment and significantly improving their quality of life. The paper in the Nov. 11 New England Journal of Medicine reports that treatment with romiplostim, which mimics the effects of a growth factor that...
