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.

An Organized Approach to 3D Tissue Engineering: IBN’s novel technique brings researchers closer to viable organ implants

Researchers at the Institute of Bioengineering and Nanotechnology (IBN) have developed a simple method of organizing cells and their microenvironments in hydrogel fibers.

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.

Open access to research publications reaching 'tipping point', said European Commission

The global shift towards making research findings available free of charge for readers—so-called 'open access'—was confirmed in a study funded by the European Commission. This new research suggests that open access is reaching the tipping point, with around 50% of scientific papers published in 2011 now available for free. This is about twice the level estimated in previous studies, explained by a refined methodology and a wider definition of open access. The study also estimates that more than 40% of scientific peer reviewed articles published worldwide between 2004 and 2011 are now available online in open access form. The study looks at the EU and some neighbouring countries, as well as Brazil, Canada, Japan and United States of America.

‘Groovy’ hologram creates strange state of light at visible and invisible wavelengths: Nanostructured device controls the intensity, phase, and polarization of light for wide applications in optics

Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have demonstrated that they can change the intensity, phase, and polarization of light rays using a hologram-like design decorated with nanoscale structures.

A new three-in-one optical element can control light’s amplitude, phase, and polarization through a wedding of old-fashioned holograms and state-of-the-art nanoscale features.
