nanotimes News in Brief

A radical new way of making structures visible at the nano level has been deve- loped at Johannes Gutenberg Univer- sity Mainz (JGU, Germany). This new method makes it possible to determine with precision the arrangement of atoms and molecules in a diverse range of ma- terials from cement to pharmaceuticals. The method was developed by Dr. Ute Kolb‘s working group at the Institute of Physical Chemistry at Mainz University. In cooperation with researchers from Spain and China, the method has now allowed the structure of a new type of fine-pore zeolite to be established.

Scientists at the University of Manchester, U.K., have come one step closer to creating the next generation of computer chips using wonder material graphene. By sandwiching two sheets of graphene with another two-dimensional material, boron nitrate, the team created the graphene ‘Big Mac’ – a four-layered structure which could be the key to replacing the silicon chip in computers.
