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.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
