International Research Team Discovers that it Takes some Heat to form Ice on Graphene Written by AZoNanoMay 27 2021 A new study from the University of Surrey, in collaboration with the University of Cambridge and Graz University of Technology (Austria), reveals that energy is needed for water to proceed through the first step of ice formation on graphene.

The molecular-level perspective of this process...

However, the exact process and its microscopic details remained elusive up to know. Anton Tamtögl from the Institute of Experimental Physics at TU Graz explains: "The first step in ice formation is called 'nucleation' and happens in an incredibly short length of t...

The first step of ice formation requires a little heat, scientists recently discovered.

Nanoscale tunneling microscopy goes contact-free MSU joins an international research team to create a new type of ‘nanoscopy’ to characterize interesting materials like never before A new microscopy technique lets researchers characterize materials with incredible precision while keeping its distance — at least from a nanoscopic perspective. Physicists from the University of Regensburg in Germany, the University of Manchester in England and Michigan State University developed the technique that enables observations at incredibly small sizes over ultrashort time scales. The invention, wh...

 E-Mail An international research team led by the University of Cologne has succeeded for the first time in connecting several atomically precise nanoribbons made of graphene, a modification of carbon, to form complex structures. The scientists have synthesized and spectroscopically characterized nanoribbon heterojunctions. They then were able to integrate the heterojunctions into an electronic component. In this way, they have created a novel sensor that is highly sensitive to atoms and molecules. The results of their research have been published under the title 'Tunneling current modulatio...
