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.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
