Scientists find a way of acquiring graphene-like films from salts to boost nanoelectronics: Physicists use supercomputers to find a way of making 'imitation graphene' from salt

Researchers from Moscow Institute of Physics and Technology (MIPT), Skolkovo Institute of Science and Technology (Skoltech), the Technological Institute for Superhard and Novel Carbon Materials (TISNCM), the National University of Science and Technology MISiS (Russia), and Rice University (USA) used computer simulations to find how thin a slab of salt has to be in order for it to break up into graphene-like layers. Based on the computer simulation, they derived the equation for the number of layers in a crystal that will produce ultrathin films with applications in nanoelectronics. Their findings were in The Journal of Physical Chemistry Letters (which has an impact factor of 8.54).

Scientists change properties of zeolites to improve hemodialysis

Scientists of Tomsk State University are working on changing physicochemical properties of zeolites using thermal and mechanical treatment. Based on the results of this research the scientists will be able to create a new material for a portable device for hemodialysis.

The scientists examined synthetic zeolite powder manufactured by SAPO-34 and natural zeolite of Tokay deposits (Hungary)

The top two rows show illustrations of crystals and solution structures of bacterial HU proteins with DNA represented by X-ray crystallography and small angle X-ray scattering, respectively. DNA strands are yellow and HU proteins are shades of blue. Soft X-ray tomography was used to visualize bacterial chromatin (in yellow) in wild type and invasive E. coli cells, shown in the bottom row.

New nontoxic process promises larger ultrathin sheets of 2-D nanomaterials

A team of scientists led by the Department of Energy's Oak Ridge National Laboratory has developed a novel way to produce two-dimensional nanosheets by separating bulk materials with nontoxic liquid nitrogen. The environmentally friendly process generates a 20-fold increase in surface area per sheet, which could expand the nanomaterials' commercial applications.
