TL;DR: In this article, the authors used the technique of ballistic Hall micromagnetometry to study the annihilation process of an individual domain in sub-micron ferromagnetic nickel disks, which allows to detect changes in magnetization as low as 5×10 4 μ B over a wide range of temperatures.

TL;DR: In this paper, the authors present measurements of a superconducting quantum interference device incorporating ballistic Josephson junctions that can be controlled individually using local field effect gates and find a highest transfer function 300 lV/U0, which compares favorably with conventional, low temperature DC SQUIDs.

TL;DR: In this paper, the authors review recent advances in graphene science and technology in the context of contributions to this special issue, and present a review of the contributions to the special issue.

TL;DR: In this paper , the authors investigated multilayer graphdiyne membranes made from a graphene-like crystal with a larger unit cell and found that despite being nearly a hundred of nanometers thick, the membranes allow fast, Knudsen-type permeation of light gases such as helium and hydrogen whereas heavy noble gases like xenon exhibit strongly suppressed flows.

TL;DR: In this article, the reduced graphene oxide is preferably formed from the reduction of graphene oxide by HI, HBr or ascorbic acid, and their uses are described and discussed.
