IRD for GC and MS
ASAP Analytical introduces their Vapor Phase IRD designed with the sensitivity and stability required to make the capillary GC/FTIR practical in the chromatography lab. The instrument requires a minimum of bench space with optimized, dedicated optics for highest sensitivity. The GC/IRD integrated software provides efficient instrument control, data acquisition with library searching. The result is a universal non-destructive IRD for routine to complex sample analysis.

‘Vortex Lattices’ May Help Explain Material Defects
What do you get when you superimpose a rotating pattern of intersecting laser beams on a spinning cloud of ultracold atoms in a thin gas? Pretty pictures, for one thing — but also a new method that could be used to simulate why and how defects arise in superconductors, important materials that are difficult to study directly.
By combining two cutting-edge laboratory creations—optical lattices and atoms in a Bose-Einstein condensate (BEC) spinning in a trap like planets orbiting the sun — physicists at JILA have developed a method of visualizing defects, or disruptions, in rotating patterns. continue
New Magnetic Polymers May Advance Spintronics Technologies
Researchers at the U.S. Department of Energy's Argonne National Laboratory have pioneered a new approach for making magnetic polymers that are held together with very strong hydrogen bonds. These polymers contain an innovative bifluoride, HF2–, building block that allows a magnetically ordered state to be obtained. The development may help lead to new techniques for faster and more versatile computer chips, among other applications. continue
CO2 Emissions Will Reduce Density of Earth's Outermost Atmosphere by 2017
Carbon dioxide emissions from the burning of fossil fuels will produce a 3 percent reduction in the density of Earth's outermost atmosphere by 2017, according to a team of scientists from the National Center for Atmospheric Research (NCAR) and Pennsylvania State University (PSU).
"We're seeing climate change manifest itself in the upper as well as lower atmosphere," said NCAR scientist Stan Solomon, a co-author of the study. "This shows the far-ranging impacts of greenhouse gas emissions."
Lower density in the thermosphere, which is the highest layer of the atmosphere, would reduce the drag on satellites in low Earth orbit, allowing them to stay airborne longer. Forecasts of upper-level air density could help NASA and other agencies plan the fuel needs and timing of satellite launches more precisely, potentially saving millions of dollars. continue
Industrial Nanomaterials Appear Vulnerable to Dispersal in Natural Environment
Laboratory experiments with a type of nanomaterial that has great promise for industrial use show significant potential for dispersal in aquatic environments – especially when natural organic materials are present.
When mixed with natural organic matter in water from the Suwannee River - a relatively unpolluted waterway that originates in southern Georgia - multiwalled carbon nanotubes (MWNTs) remain suspended for more than a month, making them more likely to be transported in the environment, according to research led by the Georgia Institute of Technology.
Carbon nanotubes, which can be single- or multiwalled, are cylindrical carbon structures with novel properties that make them potentially useful in a wide variety of applications including electronics, composites, optics and pharmaceuticals. continue
