of polymer nanoparticles for drug delivery, control of protein adsorption on materials
surfaces and protein nanofibers. In addition, the new excellence graduate school (Research
Training Group) RTG 2723: Materials‐Microbe‐Microenvironments: Antimicrobial
biomaterials with tailored structures and properties (M‐M‐M) funded by the German Science
Foundation will be introduced.
Polymer nanoparticles (PNP) became recently exceedingly popular through novel vaccination
technologies but have also major potential for fighting inflammation and cancer. These drug
release properties of the PNP depend on their structure. Yet, the literature reports little
about the structure and the properties of most PNPs, except the chemical composition. The
PNP’s crystallinity, thermal and mechanical properties are frequently ignored, even though
they may play a key role in the drug delivery properties of the PNPs.
Protein adsorption on biomaterials is the first process after implantation and determines
much of the fate of the biomaterial, such as cell adhesion, blood coagulation or infection at
the implant site. Despite decades of research, only rules of thumb exist to predict protein
adsorption behavior. We present nanotechnological approaches to control protein
adsorption using nanostructured semicrystalline polymers and crystal facets of TiO2. Selfassembled
protein nanofibers consisting of one or more proteins, potentially allow to tailor
the properties of biomaterials interfaces and to create bone mimetic structures.
Finally, the new DFG‐RTG 2723: Materials‐Microbe‐Microenvironments: Antimicrobial
biomaterials with tailored structures and properties (M‐M‐M) in Jena will be introduced. The
aim of the RTG is to provide excellent training for approximately 40 international doctoral
researchers in antimicrobial biomaterials in interdisciplinary tandem projects, connecting
materials science and medical science. The RTG pursues a new strategy by developing
antibiotic free biomaterials, where the antimicrobial action is based mainly on physical
principles. The new RTG offers ample opportunity for fruitful cooperation and exchange with
leading research institutions in Israel. -

University of WashingtonOrganizer Faculty of PhysicsContact Abstract Show full text abstract about The Legacy Survey of Space and Time (LSST), the first projec...» The Legacy Survey of Space and Time (LSST), the first project to be undertaken
at the new Vera Rubin Observatory, will be the most comprehensive optical astronomical
survey ever undertaken. Starting in 2024, Rubin Observatory will obtain panoramic images
covering the sky visible from its location in Chile every clear night for ten years.
The resulting hundreds of petabytes of imaging data, essentially a digital color movie
of the night sky, will include about 40 billion stars and galaxies, and will be used for investigations ranging from cataloging dangerous near-Earth asteroids to fundamental
physics such as characterization of dark matter and dark energy.
I will start my presentation with an overview of LSST science drivers and system design,
and continue with a construction status report for the Vera Rubin Observatory. I will
conclude with a brief discussion of a few Big Data challenges that need to be addressed
before LSST data can be used for precise cosmological measurements.

Advanced Concepts of Super-Resolution Fluorescence Microscopy
More information Time 11:00 - 12:00Location Gerhard M.J. Schmidt Lecture HallLecturer Prof. Joerg Enderlein, Sarah Amzallag
Biophysics, Georg-August-University GöttingenOrganizer Faculty of ChemistryContact Abstract Show full text abstract about With the advent of super-resolution microscopy, the last ~25...» With the advent of super-resolution microscopy, the last ~25 years have seen a revolution in optical microscopy, pushing the spatial resolution capabilities of optical microscopy towards length scales that were typically accessible only by electron microscopy. In my presentation, I will give a short overview of the different principal approaches to super-resolution microscopy. I will briefly discuss the concepts of Structured Illumination Microscopy (SIM), Stimulated Emission Depletion (STED) microscopy, and Single Molecule Localization Microscopy (SMLM). Then, I will focus on two specific techniques where our group has contributed most. The first is Image Scanning Microscopy or ISM [1-3]. This technique uses a simple combination of confocal microscopy with wide-field image detection for doubling the resolution of conventional microscopy. I will explain the physical principals behind ISM, and the various kinds of its implementation. Meanwhile, ISM has found broad and wide applications and lies behind state-of-the-art commercial systems such as the extremely successful AiryScan microscope from Carl Zeiss Jena. The second method is Super-resolution Optical Fluctuation Imaging (SOFI), which uses the stochastic blinking of emitters for overcoming the classical diffraction limit of resolution, similar to single-molecule localization microscopy, but with much relaxed demands on blinking behavior and label density [4]. The third method is Metal-Induced Energy Transfer imaging or MIET imaging [5-6]. It addresses the axial resolution in microscopy, which is particularly important for resolving three-dimensional structures. MIET is based on the intricate electrodynamic interaction of fluorescent emitters with metallic nanostructures. I will present the basic principles and several applications of this technique. -

However, we established that chiral material can act as spin filters for photoelectrons transmission, in electron transfer, and in electron transport. The effect, termed Chiral Induced Spin Selectivity (CISS), has interesting implications for the production of new types of spintronics devices and on electron transfer in biological systems. The basic effect, and its applications and implications, will be presented. -

Using functional MRI to better understand neurodevelopmental disorders and to find biomarkers of treatment response in mental illness
More information Time 12:30 - 13:30Location Gerhard M.J. Schmidt Lecture HallLecturer Prof. Keith Shafritz
Hofstra University and Feinstein Institutes for Medical Research NYOrganizer Department of Brain SciencesContact Abstract Show full text abstract about Our ability to correctly diagnose and treat mental illness i...» Our ability to correctly diagnose and treat mental illness is limited by the overlap in symptoms of many disorders, despite differing etiology. Determining the proper course of treatment is quite difficult because treating individual symptoms does not always lead to successful remission and typically involves a trial-and-error approach. Task-based functional MRI has become a highly useful tool for determining the brain regions involved in cognition and behavior in humans, with the potential to be used to find biomarkers of mental illness and treatment outcomes. Much of the research in this domain has focused on the differences in brain activation between groups of individuals with specific mental disorders and typically developing “control” groups. However, by relating brain activation patterns of clinical groups to symptom severity, developmental processes, and response to treatment at the individual level, we can determine brain-based markers that have the potential to be used as diagnostic tools in the future and to determine whether certain treatments would be helpful based on specific brain activation patterns. In this talk, I will present data from studies using task-based functional MRI in autism spectrum disorder, schizophrenia, and childhood adversity that illustrate the potential of this technology for diagnostic and treatment purposes. I will also discuss the promises and limitations of using fMRI as a clinical tool.

Among all the existing methods optically based ones are very well adapted to quantitatively probe optoelectronic properties at any stage. We here present the use of multidimensional imaging techniques that record spatially, spectrally and time resolved luminescence images. We will discuss the benefits (and challenges) of looking into energy conversion systems from high dimensions perspective and those of dimensional reduction for improved intelligibility through some examples, mostly drawn from halide perovskite materials and device. These examples will help visit questions related to efficient transport and conversion in solar cells, as well as questions related to chemical and operational stability of the devices.

The techniques resulting from this capability may lead to a considerable improvement in several sensing modalities, for example atomic clocks and the measurement of magnetic fields on the nanoscale.
As an example for a quantum sensor, and of course after introducing the underlying concepts of quantum sensing, I will present the nitrogen-vacancy defect, or color center, in diamond. First, I will explain how one can use it to measure magnetic and electric fields, temperature, strain and even pH levels. Then, I will try to show what the "quantum advantage" that is possible in this class of sensors and will give a few examples from research activities in our group. Finally, I will also discuss several industrial applications, some of which are already in use or in development around the world.

How microbial interactions shape the exo-metabolic landscape of the ocean
More information Time 11:30 - 12:30Location Nella and Leon Benoziyo Building for Biological SciencesLecturer Dr. Constanze Kuhlisch Organizer Department of Plant and Environmental SciencesContact Abstract Show full text abstract about Algal blooms are events of high primary productivity and rap...» Algal blooms are events of high primary productivity and rapid population growth that can cover vast oceanic regions. They thus play an important role for the marine food web and for the global carbon and sulfur cycling. Furthermore, algal blooms are hotspots of microbial interactions with e.g. grazers, heterotrophic bacteria, fungi and viruses. These interactions are mediated by metabolite signals, they can modulate metabolic pathways and can induce biosynthetic gene clusters – the diversity of microbial communities in natural blooms is thus crucial in understanding the chemical ecology of algal blooms. In my talk, I will show how lipid remodeling during the infection of E. huxleyi blooms by its giant virus imprints the marine dissolved organic matter pool. Further, I will present how a tripartite interaction between alga, virus and associated microbes leads to a unique halogenation activity during bloom demise. Lastly, I will discuss the potential ecological role of indole derivatives that accumulate in the blooms of E. huxleyi. -
