    The fast dynamics occurring in natural processes increases the difficulty of creating biomaterials capable of mimicking Nature. Within synthetic biomaterials, water-soluble supramolecular polymers show great potential in mimicking the dynamic behavior of these natural processes. In particular, benzene-1,3,5-tricaboxamide (BTA)-based supramolecular polymers have shown to be highly dynamic through the exchange of monomers within and between fibers, but their suitability as biomaterials has not been yet explored. Herein we systematically study the interactions of BTA supramolecular polymers bearing either tetraethylene glycol or mannose units at the periphery with different biological entities. When BTA fibers were incubated with bovine serum albumin (BSA), the protein conformation was only affected by the fibers containing tetraethylene glycol at the periphery (BTA-OEG4). Coarse-grained molecular simulations showed that BSA interacted with BTA-OEG4 fibers rather than with BTA-OEG4 monomers that are present in solution or that may exchange out of the fibers. Microscopy studies revealed that, in the presence of BSA, BTA-OEG4 retained their fiber conformation although their length was slightly shortened. When further incubated with fetal bovine serum (FBS), both long and short fibers were visualized in solution. Nevertheless, in the hydrogel state, the rheological properties were remarkably preserved. Further studies on the cellular compatibility of all the BTA assemblies and mixtures thereof were performed in four different cell lines. A low cytotoxic effect at most concentrations was observed, confirming the suitability of utilizing functional BTA supramolecular polymers as dynamic biomaterials.

    International conference within the ERC Locus Ludi at the Swiss Museum of Games, with public lecture by Michel Manson and public opening of Saype artwork, Play in the lake (September, 17-19..2018). For more see: https://locusludi.ch. Play and games provide a privileged access to past societal norms, values, identities, and collective imaginary. People play all over the world and throughout history, but they do not play the same games, nor do they attribute the same meaning and function to play. The aim of this pluridisciplinary conference is to investigate how this past patrimony can be methodologically reconstructed. Three sessions will address first how the Ancients defined play and games by analysing their vocabulary in order to reconstruct an emic definition. Beyond the common association of child and play (in Greek, paidia, ‘game’, pais, the child, and paideia, ‘education’, share the same root, in Latin ludus means ‘play’, ‘school’ and ‘rhetorical games’), the views are more complex and nuanced. Identifying ludic material and practices archaeologically as well as in iconography is also a debatable issue. The second session concerns the sources available and their bias associated with literary genre, such as oniromancy, proverbs and the lexicon of Pollux. A major challenge is the reconstruction of a mostly oral patrimony, of lost children’s lore and agency. The third session examines the transmission process of these practices from one generation to the next, addressing crucial issues about continuities and discontinuities, as well as about the definition of a “traditional” game

    Presentation slides prepared for a series of eight lectures on gravitational waves (GWs) from the early Universe given at the 46th Heidelberg Physics Graduate Days (April 6-9, 2021). This lecture series is aimed at physics graduate students with rudimentary background knowledge of general relativity and cosmology and covers the following topics: Lecture 1A: Definition and properties of GWs in general relativity (GWs in linearized gravity, propagation in the expanding Universe, stochastic GW backgrounds in cosmology) Lecture 1B: An overview of existing and future GW experiments, plus the basics behind the data analysis (GW interferometers, experimental sensitivity curves, pulsar timing arrays, cosmic microwave background) Lecture 2A: GWs in big-bang cosmology (frequency-temperature relation, integrated GW energy density, bounds from Neff, GW signal from a generic source) Lecture 2B: GWs in inflationary cosmology (introduction to inflation, amplification of tensor perturbations, transfer function) Lecture 3A: Various exotic mechanisms of generating GWs (axion inflation, audible axions, modified theories of gravity, scalar-induced GWs and primordial black holes) Lecture 3B: GWs from strong first-order phase transitions in the early Universe (introduction to cosmological phase transitions, GW signal from runaway and non-runaway phase transitions, models and sensitivity curves) Lecture 4A: GWs from cosmic defects (introduction to cosmic defects, GW signal from a general defect network, GWs from cosmic strings) Lecture 4B: NANOGrav signal, possible interpretations, and an outlook onto the field in the coming years (overview of the NANOGrav measurement, possible astrophysical and BSM interpretations, special emphasis on cosmic strings, upcoming pulsar timing data) The file "graddays_2021_gravitational_waves_kai_schmitz.pdf" is a 881-page PDF file containing the slides of all lectures together.
