China Hit by 'Largest Ever' Hack Attack

Large parts of China’s Internet went dark this past weekend as the country came under what the Beijing government is calling the “largest ever” hack attack on Chinese sites.

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.

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.
