Klaus Kern

Klaus Kern is Professor of Physics at EPFL and Director and Scientific Member at the Max-Planck-Institute for Solid State Research in Stuttgart, Germany. He also is Honorary Professor at the University of Konstanz, Germany. His present research interests are in nanoscale science, quantum technology and in microscopy at the atomic limits of space and time. He holds a chemistry degree and PhD from the University of Bonn and a honorary doctors degree from the University of Aalborg. After his doctoral studies he was staff scientist at the Research Center Jülich and visiting scientist at Bell Laboratories, Murray Hill before joining the Faculty of EPFL in 1991 and the Max-Planck-Society in 1998. Professor Kern has authored and coauthored close to 700 scientific publications, which have received nearly 60‘000 citations. He has served frequently on advisory committees to universities, professional societies and institutions and has received numerous scientific awards and honors, including the 2008 Gottfried-Wilhelm-Leibniz Prize and the 2016 Van‘t Hoff Prize. Prof. Kern has also educated a large number of leading scientists in nanoscale physics and chemistry. During the past twenty-five years he has supervised one hundred PhD students and sixty postdoctoral fellows. Today, more than fifty of his former students and postdocs hold prominent faculty positions at Universities around the world.

Magalí Alejandra Lingenfelder

Magalí Lingenfelder is currently leading the Max Planck-EPFL Laboratory for Molecular Nanoscience. Her vision is to create atomically tailored interfaces for applications in two distinct areas of urgent technological and societal relevance: energy conversion and smart antimicrobial interfaces. To access the nanoscale, her group uses a combination of state-of-the-art scanning probe microscopy and solid state spectroscopy, allowing the study of kinetic processes in-situ under liquid flow and potential control conditions (operando electrocatalysis). She made seminal contributions to the field of metal-organic coordination networks on solid surfaces, and received the Otto Hahn medal in 2008 for the microscopic understanding of the chiral recognition process with submolecular resolution. She is a committed mentor, and since her relocation from the Lawrence Berkeley National Laboratory, USA to EPFL in 2013, she directed 3 MSc. theses, 4 PhD theses and 4 postdocs. She advocates for problem-oriented interdisciplinary research: she led 5 international research consortiums, delivered over 40 invited presentations and organized 9 conferences and 4 doctoral schools. In 2018, the Royal Society of Chemistry included her work in the first collection “Celebrating Excellence in Research: 100 Women of Chemistry”.

Voltage drop

In electronics, voltage drop is the decrease of electric potential along the path of a current flowing in a circuit. Voltage drops in the internal resistance of the source, across conductors, across contacts, and across connectors are undesirable because some of the energy supplied is dissipated. The voltage drop across the load is proportional to the power available to be converted in that load to some other useful form of energy. For example, an electric space heater may have a resistance of ten ohms, and the wires that supply it may have a resistance of 0.

Électron

L'électron, un des composants de l'atome avec les neutrons et les protons, est une particule élémentaire qui possède une charge élémentaire de signe négatif. Il est fondamental en chimie, car il participe à presque tous les types de réactions chimiques et constitue un élément primordial des liaisons présentes dans les molécules. En physique, l'électron intervient dans une multitude de rayonnements et d'effets.

Diviseur de tension

Le diviseur de tension est un montage électronique simple qui permet de diminuer une tension d'entrée, constitué par exemple de deux résistances en série. Il est couramment utilisé pour créer une tension de référence ou comme un atténuateur de signal à basse fréquence. Les tensions du diviseur sont reliées à la masse et les deux résistances R1 et R2 sont connectées en série. Une tension U est appliquée en entrée sur ces deux résistances et la tension de sortie est mesurée aux bornes de R2.

Le noyau d', agrandi à droite, est formé de deux protons et de deux neutrons. redresse=1.25|vignette|Atomes de carbone à la surface de graphite observés par microscope à effet tunnel. Un atome est la plus petite partie d'un corps simple pouvant se combiner chimiquement avec un autre. Les atomes sont les constituants élémentaires de toutes les substances solides, liquides ou gazeuses.

Tension électrique

La tension électrique est la circulation du champ électrique le long d'un circuit électrique mesurée en volts par un voltmètre. Elle est notée V aux bornes d'un dipôle. La notion de tension électrique est souvent confondue avec celle de la « différence de potentiel électrique » (DDP) entre deux points d'un circuit électrique. Les deux notions sont équivalentes en régime stationnaire (indépendant du temps).
