On Wednesday, June 10th 2019, a group of female physicists from various different research groups of the Department of Physics at the University of Basel set out on a journey to Beckenried, NW, at the shore of Lake Lucerne, to go on their first Women in Physics networking hike. The goal of this event, which is also a part of the NCCR QSIT equal opportunities program, is to get to know each other, talk about both physics-related and -unrelated topics in a relaxed environment, and build up a sense of community among the female members of the department. After taking the cable car to Klewenalp, which offered amazing views of Lake Lucerne and the surrounding mountains, our path led us uphill to the SAC hut Brisenhaus, and from there in a big loop through meadows and forests back to Klewenalp. There, everyone was happy to get their well-deserved coffee and enjoy the sun until the cable car took us back down and we started our way home back to Basel.
Nowadays materials science faces an even more ambitious task: creating materials by design, that is engineering materials with tailor made properties, typically because they can be useful for some specific applications. A way to achieve this goal is creating superlattices, periodic structures made of an ordered sequence of building blocks of different materials, whose properties that can be tuned by controlling the stacking of the building blocks.
In the framework of a collaborative research project led by Ilaria Zardo, from the University of Basel (Switzerland), counting with the collaboration of the Institut de Ciència de Materials de Barcelona (ICMAB-CSIC) (Spain), the Universitat Autònoma de Barcelona (UAB) (Spain) and the Technical University of Eindhoven (The Netherlands), the tuning of the vibrational properties of a crystal phase superlattice has been demonstrated for the first time. This superlattice is different from the conventional ones, since its basic LEGO® bricks used as building blocks, rather than made of different materials, are made of different crystal phases of the same material. This finding has been published in the journal Nano Letters and highlighted by the editor in the journal cover .
In dem Science-Fiction-Klassiker „Zurück in die Zukunft II“ flitzt Filmschauspieler Michael J. Fox auf einem Skateboard durch die Straßen, das keine Rollen besitzt, sondern wie ein Hovercraft über dem Boden schwebt. Genau an dieser technologischen Vision tüftelten auch Felix Sewing und Alex Korocencev. Ihr Gefährt basiert auf vier rotierenden Scheiben, die auf einer darunterliegenden Metallplatte ein kräftiges, abstoßendes Magnetfeld hervorrufen können. Die Tragkraft des Boards ist durchaus beeindruckend, der Prototyp kann ein beträchtliches Gewicht stemmen. Zudem ist es möglich, die Rotorscheiben einzeln zu kippen, wodurch sich das Brett gezielt lenken lässt. Mittlerweile funktioniert die Technik so gut, dass die beiden Jungforscher für die darin verwendete Magnetanordnung ein Patent beantragt haben.
Congratulations to the winner of the golden chalk, the golden correction pen & the golden scale!
Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.
Der Physiker Dr. Matteo Fadel von der Universität Basel gehört zu den vier jungen Forschenden an Schweizer Hochschulen, die von der Akademie der Naturwissenschaften (SCNAT) mit dem Prix Schläfli 2019 ausgezeichnet werden. Der Preis wird jährlich für die vier besten Doktorarbeiten in Naturwissenschaften vergeben.
The use of potassium bromide in the production of graphene on a copper surface can lead to better results. When potassium bromide molecules arrange themselves between graphene and copper, it results in electronic decoupling. This alters the electrical properties of the graphene produced, bringing them closer to pure graphene, as reported by physicists from the universities of Basel, Modena and Munich in the journal ACS Nano .
For the first time, physicists at the University of Basel have succeeded in measuring the magnetic properties of atomically thin van der Waals materials on the nanoscale. They used diamond quantum sensors to determine the strength of the magnetization of individual atomic layers of the material chromium triiodide. In addition, they found a long-sought explanation for the unusual magnetic properties of the material. The journal Science has published the findings.
The European Research Council has awarded two University of Basel scientists each a generously endowed ERC Advanced Grant. Biologist Professor Alex Schier and physicist Professor Ernst Meyer will each receive funding in the six figures for their innovative research projects.
