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.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
