Modifying surfaces by means of nanostructured reliefs to prevent the spread of bacteria
Friday, July 20, 2012 - 08:17

Researchers at the Institute for Agrobiotechnology (a mixed research centre set up by the Public University of Navarre, the CSIC-National Scientific Research Council, and the Government of Navarre) are designing, by means of laser application, nanostructured reliefs on surfaces so that they acquire antibacterial properties and are more resistant to the formation of bacterial biofilms.

World Record: Scientists from Northern Germany Produce the Lightest Material in the World
Tuesday, July 17, 2012 - 07:42

A network of porous carbon tubes that is three-dimensionally interwoven at nano and micro level – this is the lightest material in the world. It weights only 0.2 milligrams per cubic centimetre, and is therefore 75 times lighter than Styrofoam, but it is very strong nevertheless. Scientists of Kiel University (KU) and Hamburg University of Technology (TUHH) have named their joint creation “Aerographite”. The scientific results were published as the title story in the scientific journal “Advanced Materials” on July, 3rd. Today (Tuesday, July 17th) it is presented to the public.

Unprecedented Subatomic Details of Exotic Ferroelectric Nanomaterials
Sunday, July 8, 2012 - 20:36

Brookhaven scientists used a technique called electron holography to capture images of the electric fields created by the materials’ atomic displacement with picometer precision — that’s the trillionths-of-a-meter scale crucial to understanding these promising nanoparticles. By applying different levels of electricity and adjusting the temperature of the samples, researchers demonstrated a method for identifying and describing the behavior and stability of ferroelectrics at the smallest-ever scale, with major implications for data storage.

A new approach to water desalination: Graphene sheets with precisely controlled pores
Monday, July 2, 2012 - 08:48

MIT researchers have come up with a new approach using a different kind of filtration material: sheets of graphene, a one-atom-thick form of the element carbon, which they say can be far more efficient and possibly less expensive than existing desalination systems.
