A new and economical technology for the separation and capture of carbon dioxide from industrial processes could lead to a significant reduction in greenhouse-gas emissions to the atmosphere. Scientists at the Department of Energys Los Alamos National Laboratory are developing a new high-temperature polymer membrane to separate and capture carbon dioxide, preventing its escape into the atmosphere. This work is part of the DOE Carbon Sequestration Programs mission to reduce the amount of carbon dioxide emitted into the environment from industrial processes.
Growing concern about the potential worldwide environmental impacts, such as global warming and acidification of the oceans, from the vast amounts of carbon dioxide released from the combustion of fossil fuels prompts scientists to research and develop methods for carbon sequestration. National studies estimate approximately 30 percent of human-caused carbon dioxide emissions are a result of power-producing industries.
At the American Geophysical Union conference today in Washington D.C., Jennifer Young, principal investigator for Los Alamos carbon dioxide membrane separation project, presents data on a new polymeric-metallic membrane that is operationally stable at temperatures as high as 370 degrees Celsius. To date, polymer membranes commercially available for gas separation are limited to maximum operating temperatures of 150 degrees Celsius.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
