Two become one with the 3D NanoChemiscope - unique surface analysis instrument

The 3D NanoChemiscope is a miracle of state-of-the-art analysis technology. As a further development of well-known microscopic and mass spectroscopic methods, it maps the physical and chemical surfaces of materials down to the atomic level. This instrument, which is unique in the world, not only delivers high-definition images; it also knows what it is "seeing".

Physicists from Bielefeld University have developed a new method of fabrication

In the future, carbon nanomembranes are expected to be able to filter out very fine materials. These separating layers are ultrathin, consisting of just one layer of molecules. In the long term, they could allow to separate gases from one another, for example, filtering toxins from the air.

48034.jpgUsing a new process the team working with Professor Dr. Armin Gölzhäuser has produced twelve different nanomembranes. The three images were made using the Bielefeld Helium Ion Microscope and show nanomembranes made from various starting materials.

New tests for determining health and environmental effects of nanomaterials

A group of international experts from government, industry and academia have concluded that alternative testing strategies (ATSs) that don't rely on animals will be needed to cope with the wave of new nanomaterials emerging from the boom in nanoscience and nanotechnology.

From more than 40 countries and 30 U.S. states, people around the world shared more than 1,400 images of themselves as part of the Wave at Saturn event organized by NASA's Cassini mission. That event on July 19, 2013, marked the day the Cassini spacecraft turned back toward Earth to take our picture as part of a larger mosaic of the Saturn system.

Littlest Continent Had Biggest Role in Sea Level Drop

Changes in Australia's mass as reported by data from NASA's Gravity Recovery and Climate Experiment (GRACE) satellites from June 2010 to February 2011. Areas in greens and blues depict the greatest increases in mass, caused by excessive precipitation. The contour lines represent various land surface elevations. A new study co-authored and co-funded by NASA finds extensive flooding in Australia, combined with the continent's soils and unique topography, were the biggest contributors to the drop in global sea level observed in 2010 and 2011.
