We interviewed the French scientist Jean-Marie Dubois, specialist in quasicrystals (ordered, but aperiodic structures on solid materials) and pioneer in patenting applications for them. He told us a little about his main contributions to the field of Materials and gave a teaser on the theme of his plenary lecture in the XIII SBPMat Meeting: he will talk about quasicrystal structures, found in metallic alloys, polymers, oxides and artificial nanostructures, and their unprecedented properties. In the picture, Jean-Marie Dubois (on the left) and Dan Shechtman, who received a Nobel Prize in 2011 for the quasicrystals, using equal ties, both decorated with the Penrose tiling, an example of aperiodicity.  Read our interview with Jean-Marie Dubois here.

We also interviewed the Italian chemist Roberto Dovesi, one of the creators of CRYSTAL, a computational tool for ab initio quantum calculations used in the study of several solid materials properties. The CRYSTAL code is currently used in over 350 laboratories around the world.  In his plenary lecture in the XIII SBPMat Meeting, Dovesi will attempt to demonstrate that today quantum simulations may be very useful tools to complement experiments.  Read our interview with Roberto Dovesi here.

Featured paper with Brazilian participation

A group of scientists, coordinated by Brazilian researchers, used a Helium Ion Microscope (HIM) located in Silicon Valley, in the United States,  to engrave nanometric periodic patterns in graphene sheets, giving an innovative use to the instrument. The fast, simple and precise technique could be used by the electronics industry to produce graphene semiconductive devices, which could replace the silicon ones. The lead author of the paper published in Applied Physics Letters told us the story behind the study and announced that, soon, Brazil is going to have its first HIM.  Read the story.
