In this research, copper nanocomposites reinforced by graphene nanoplatelets (GNPs) were fabricated using a wet mixing method followed by a classical powder metallurgy route. In order to find the best dispersion technique, ball milling and wet mixing were chosen.
Researchers from the University of Minnesota College of Science and Engineering have found yet another remarkable use for the wonder material graphene—tiny electronic “tweezers” that can grab biomolecules floating in water with incredible efficiency. This capability could lead to a revolutionary handheld disease diagnostic system that could be run on a smart phone.
An international team of researchers from Empa, the Max Planck Institute for Polymer Research in Mainz and the University of California at Berkeley has succeeded in growing graphene ribbons exactly nine atoms wide with a regular armchair edge from precursor molecules. The specially prepared molecules are evaporated in an ultra-high vacuum for this purpose. After several process steps, they are put on a gold base to form the desired nanoribbons of about one nanometer in width and up to 50 nanometers in length.
The Fraunhofer Institute for Manufacturing Engineering and Automation IPA uses the tagline: “We manufacture the future”.
Certainly as one of the leading research institutes in the world for the development of automotive technology, Fraunhofer has a global reputation for delivering the latest cutting edge breakthroughs in any technology associated with the automotive industry from energy storage to lightweight engineering.
You probably won’t find many nanotechnologists at New York Fashion Week, but that may soon change thanks to the work of Felice Torrisi, a researcher at the Cambridge Graphene Center who is pioneering the future of wearable tech.
In this paper, the authors report the use of a simple and inexpensive electrophoretic deposition (EPD) technique to develop thin, uniform, and transparent graphene oxide (GO) coating on copper (Cu) substrate on application of 10 V for 1 s from an aqueous suspension containing 0.03 wt % graphene oxide.
Imaging electrons can help scientists better understand exotic electronic states, such as electricity that travels through wires without loss. The team created images of superfast electrons trapped as they tunnel through energy barriers in graphene. They visualized this unusual tunneling for the first time (Nature Physics, “Imaging electrostatically confined Dirac fermions in graphene quantum dots”).
In November, Pan European Networks attended the 4th Graphene New Materials and 15th HVM Conference in Cambridge, UK, and there heard Professor Andrea Ferrari – director of the Cambridge Graphene Centre and chair of the management panel for the €1bn Graphene Flagship project, discuss some of the challenges experienced when attempting to move graphene – and, indeed, any other material – from the laboratory to the marketplace.
A novel solid-phase microextraction fiber was prepared using graphene oxide/β-cyclodextrin (GO/β-CD) composite as a coating material immobilized on a stainless steel wire using sol–gel technique. The coating has large surface area with uniform porous structure, stable performance at high temperature, and good coating preparation reproducibility.
There are many other 2D materials than graphene that exhibit a hexagonal array and are uni-atomic. A team of researchers from Brazil and Germany have used theoretical ab-initio methods to investigate how other group IV 2D materials, the so-called X-enes, interact when deposited onto a graphene-silicon carbide substrate.
