Accurate topography of the seabed with CryoSat



The European Space Agency (ESA) will use its satellite CryoSat, and altimeter that incorporate, to monitor the seabed. Experts expect this mission, combined with three or more years of ocean mapping, will lead to a global seafloor topography (bathymetry) between two and four times more accurate than currently available measures.

Reproduce of a structure of five rings


A team of scientists has shaped and reproduced the structure of 5-membered ring as small as possible, about 100,000 times thinner than a human hair. A collaboration between the Royal Society of Chemistry, University of Warwick, both in the UK, and IBM Research - Zurich (Switzerland), has allowed researchers to give life to a single molecule in an image, using a combination of synthetic chemistry intelligent, and imaging techniques.

manage to cut graphene accurately with a nanorobot



A team of researchers from China and the U.S. has been a method to cut graphene accurately with a nanorobot that is based on an atomic force microscope. The work, entitled 'Court graphene controlled by a nanorobot based on an atomic force microscope', was published in 'Scientia Sinica'.

Graphene is a two-dimensional stable structure has attracted worldwide attention in recent years due to its excellent electronic properties, physical and mechanical properties and its wide range of applications. It has been shown experimentally that the electrical properties of graphene are closely related to its size, geometry and structure, therefore, make the graphene having the desired shape, it is essential for practical application.
