Topological transitions and cell-cell adhesion properties in biological development
Corominas Murtra, Bernat, Ass.-Prof. PhD, Institute of Biology - University of Graz

The biological developmental process —the process that starts with one fertilized cell and ends with the fully developed individual— implies precise but significant changes in the geometry and structure of the embryonic tissues. Recent results show that apparently minor chang ... more

Solvation of ions, surfactants and polymers at interfaces and in confinement
Douwe Jan Bonthuis, ITPCP, TU Graz

In contact with aqueous solutions, many interface types spontaneously acquire a surface charge through deprotonation, adsorption of charged species, or both. Moreover, modification of surface properties by polymer adsorption is a widely used technique to tune interactions in expe ... more

Nanophotonics meet Optical Fibers: a flexible concept for single-virus sensing, achromatic light focusing and optical trapping
Prof. Dr. Markus A. Schmidt, Leibniz Institute of Photonic Technology e.V. / Otto Schott Institute of Material Research Friedrich Schiller / University Jena ,Germany

Optical fibers provide a waveguide platform with unique advantages, especially in the fields of bioanalytics and life sciences. In this talk, I will report our recent results on fibers (i) that are interfaced with nanostructures and (ii) that are used for the characterization of ... more

Flavour matters – Highlights from the LHCb experiment
Prof. Dr. Stephanie Hansmann-Menzemer, Physikalisches Institut, Universität Heidelberg

The Large Hadron Collider (LHC) close to Geneva holds many records. Amongst others, it is the world largest flavour factory. More than 10^12 particles containing bottom quarks and even more containing charm quarks have been recorded by the LHCb experiment, in recent years. Exploi ... more

Coulomb interactions in conventional Superconductivity
Antonio Sanna, Max Planck Institute of Microstructure Physics - Halle

First principle methods to simulate conventional superconductors rely, primarily, on the accurate calculation of the electron phonon coupling. However, phonon mediated attraction is partly compensated by an excess electron-electron Coulomb repulsion associated with the formatio ... more

Feeling Life with Light
Kareem Elsayad, Advanced Microscopy, Vienna Biocenter Core Facilities

The colour of light scattered from an object can give us information on its chemical consistency. For example, a moldy apple will be a different colour to a fresh one. If we analyze the spectrum of colours even more carefully and under special illumination conditions we can even ... more

Nanocomposites and polymer thin films: from gas phase synthesis to functional applications
Franz Faupel, Kiel University

Highly filled particulate metal-dielectric nanocomposites films have unique functional properties with hosts of applications. To explore collective interactions between the particles, we control the particle separation on the nm scale by employing vapor phase deposition, which is ... more

Dielectric Mie voids
Dr. Mario Hentschel, University of Stuttgart - 4th Physics Institute

Manipulating light on the nanoscale has become a central challenge in metadevices, resonant surfaces, nanoscale optical sensors and many more, and it is largely based on resonant light confinement in dispersive and lossy metals and dielectrics. I will discuss a novel paradigm in ... more

Mesoscale phase transformations in beyond-intercalation-type batteries
Christian Prehal, Department of Information Technology and Electrical Engineering, ETH Zürich, Switzerland,

Realizing beyond intercalation-type batteries, such as Metal-sulfur (Me-S) batteries, could be game-changing due to a theoretical specific capacity amongst the highest of all batteries paired with the low cost and sustainability of sulfur. However, the insufficient understanding ... more

Nuclear Quantum Effects in Ice - New Insights from Computational Modelling
Jörg Meyer, Leiden University

In crystalline phases of water nuclear quantum effects manifest themselves quite prominently in macroscopic thermodynamic properties, like for example density change at low temperatures [1] upon substitution of a light by a heavier isotope or phase transition enthalpies [2]. The ... more

Focused electron beam nanoprinting: How to twist physics with chemistry for nanoscale metal additive manufacturing
Ivo Utke, Swiss Federal Laboratories for Materials Science and Technology

Amongst various 3D additive manufacturing methods reviewed for metals [1], nanoprinting with focused electron beams offers most shape flexibility together with smallest print size. Rooted in high-tech industry as powerful maskless, minimally invasive nanofabrication platform for ... more

Out of the Crystalline Comfort Zone: ML-Empowered Modelling of Operando Energy Conversion Systems
Karsten Reuter, Fritz-Haber Institute,

Operando spectroscopies and microscopies reveal a highly dynamic behavior of interfaces in energy conversion systems. Insufficient insight and the concomitant inability to control or exploit the corresponding strong structural and compositional modifications centrally limits the ... more
