This mosaic of images from the Navigation Camera (Navcam) on NASA's Mars rover Curiosity shows the scene from the rover's position on the 376th Martian day, or sol, of the mission (Aug. 27, 2013). The images were taken right after Curiosity completed the first drive during which it used autonomous navigation on unknown ground.

EU and Russian scientists join efforts in development new nanomaterials for medical implants

With the ageing of European population, more and more people find themselves in need of dental or bone implants, which should help them to continue normal life even after mechanical damage or medical operations.

Size Matters as Nanocrystals Go Through Phases: Berkeley Lab Researchers at the Molecular Foundry Reveal Fundamental Size-Dependence of Metal Nanocrystals Undergoing Phase Transitions

Understanding what happens to a material as it undergoes phase transformations - changes from a solid to a liquid to a gas or a plasma - is of fundamental scientific interest and critical for optimizing commercial applications. For metal nanocrystals, assumptions about the size-dependence of phase transformations were made that now need to be re-evaluated.

48048.jpgPalladium nanocubes interacting with hydrogen gas were directly observed through in situ luminescence to reveal that size can make a much bigger difference on phase transformations than scientists previously believed.

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.
