"Natural and Synthetic Polymeric Systems under


Controlling the response of polymeric materials against surrounding environment holds promise to engineer novel nanostructured materials. Particularly, constraints imposed by nanometer-scale confinement lead to significant changes in the bulk equilibrium behavior of chained molecules, breaking the symmetry in the assembled structure....

"Investigating Magnetic Soft Matter"


Ferrogels are hydrogels that additionally contain magnetic single-domain particles and whose properties can be controlled by using external magnetic fields. We will present recent results on the microstructure, the magnetic behavior, and the mechanical and viscoelastic properties of 2D and 3D magnetic gels on the basis of 2 microscopic particle models. In the first model the nano-magnets are part of the chain monomers, whereas in the second model the magnetic particles are restricted to the network nodes....

"DNA under force: New insights from simulations"


Separation of a double stranded DNA (dsDNA) is prerequisite for the essential cellular processes, such as, replication and transcription. It is now well known that DNA is stabilized by inter- and intra- molecular interactions. Single Molecular Force Spectroscopy (SMFS) techniques, e.g. optical tweezers, magnetic tweezers and atomic force microscopy, have emerged as powerful tools to investigate these interactions. These experiments have provided various insights and understanding of biological processes at the molecular level....

"Experimental and Computational Studies on the Dynamics of Confined Water"


Water in confinements of nanoscopic size and in mixtures with various molecules, ranging from alcohols to proteins, is of great relevance in many fields, from biology to geology. For these systems, the water properties can be strongly affected by finite-size effects and specific interface interactions. To gain fundamental insights, we combine nuclear magnetic resonance (NMR) and broadband dielectric spectroscopy (BDS) with molecular dynamics (MD) simulations...

"Correlating Polymer Crystals via SelfInduced Nucleation"


Crystallizable polymers often form multiple stacks of uniquely oriented lamellae, which have good registry despite being separated by amorphous fold surfaces. These correlations require multiple synchronized, yet unidentified, nucleation events. Here, we demonstrate that in thin films of isotactic polystyrene, the probability of generating correlated lamellae is controlled by the branched morphology of a single primary lamella...

"Are complex microgels special?"


Multi-sensitive, “smart” microgels display a variety of properties that distinguish them from rigid colloidal particles. The swelling of the soft particles can be controlled via the chemical composition as well as the morphology of the particle. Due to the chemical structure of the microgels, their size can respond to variations, e.g., of temperature, pH, pressure or solvent composition. The porosity of the microgels further allows for the uptake and release of guest species, which can be controlled by external stimuli....

"Kinetics of collapse and aggregation in thermoresponsive micellar block copolymer solutions"

Thermoresponsive, polymeric hydrogels respond in a controlled and reversible way with a volume change to a small change of temperature across the cloud point. These switchable and nanostructured materials are of great interest for controlled molecular ultrafiltration. A widely used thermoresponsive polymer is poly(N-isopropylacrylamide) (PNIPAM) which exhibits a cloud point at 32 °C. We investigate self-assembled, physically crosslinked thermoresponsive hydrogels formed by amphiphilic, symmetric triblock copolymers having short, fully deuterated polystyrene (P(S-d8)) end blocks and a large (PNIPAM) middle block.

“Aβ-oligomer targeted therapy and diagnosis of Alzheimer's disease.”


Alzheimer’s disease (AD) is a progressive neurodegenerative disorder. Several lines of evidence suggest a central role of amyloid-β-peptide (Aβ) in the pathogenesis of AD. More than Aβ fibrils, small soluble and prion-like Aβ oligomers are suspected to be the major toxic species responsible for disease development and progression. Therefore, these oligomers should be our major target for therapy and used as the most direct biomarker for diagnosis and therapy monitoring..,.

"Dynamics and thermodynamics of glasses in bulk and under confinement"


Glass-forming systems have been the subject of intense research in the last decades. Within this context the following topics have been recently debated: i) the glassy dynamics in nanoscale confinement, with special attention to thin polymer films; and ii) the fate dynamics and thermodynamics below the laboratory glass transition temperature (Tg), namely that obtained at cooling rates of several kelvin per minute. In this seminar, first of all I critically discuss the recent advancements in the understanding of glassy dynamics in confinement...

"Nanochemistry: Applications in surface functionalization, self-assembly and nanofabrication"


The availability of new materials, i.e., graphene, carbon nanotubes or inorganic plasmonic nanoparticles, opened up appealing possibilities to access novel material properties. While the resulting properties offer tremendous potential for applications, in many cases the handling and implementation of these materials into devices and functional materials sometimes imposes challenges to allow for the utilization of these materials. Frequently, chemical derivatization, surface coatings as well as the availability of novel synthesis strategies can help to solve these problems...

"Ultrafast Carrier Dynamics in Graphene and Graphene Nanostructures"

Graphene is an attractive candidate for many optoelectronic applications because of its vanishing bandgap and high carrier mobility. An essential process for such applications is the dissipation of the energy of photoexcited charge carriers in the material. Two competing energy relaxation mechanisms for optically excited carriers exist: They can (i) thermalize with intrinsic carriers near the Fermi level, heating them to higher energy states through the process of ‘hot carrier multiplication’; or ...

"Corrections to Chain Ideality in Polymer Melts: Bulk, Thin Films and Pores"


An important concept in polymer physics is the Flory ideality hypothesis. This hypothesis states that polymer chains in a melt have random-walk-like conformations. However, theoretical [14] and numerical results [3,5] suggest that this view is an oversimplification. There are noticeable deviations from chain ideality,...

"Tailormade Polymer Monolayers and Networks for Microsystems and Engineered Biointerfaces"


All interactions of materials with their respective environments are controlled by the topography and chemical composition of their surfaces. Examples are the adhesion between different objects, wetting of surfaces by contacting liquids and the adsorption of molecules from the surrounding medium. Accordingly it is important to develop chemical tools which allow the attachment of tailor-mode polymer molecules to surfaces of different chemical composition. In the presentation a new strategy will be presented which allows to generate novel, micropatterned polymer coatings with tailor-made properties with high spatial resolution on a variety of different substrates, ranging from typical oxides to polymers and biological materials [1-5]...

"What controls the relaxation time in glass-forming liquids and polymers? New insights from density scaling and the isomorph theory"


The relaxation time of a supercooled liquid increases dramatically upon lowering temperature or increasing density; the same applies for the alpha relaxation time of polymeric systems. In extreme cases a 1% temperature decrease leads to more than a factor of ten increase of the relaxation time. The relaxation time is typically probed as the inverse dielectric loss-peak frequency, but ...

"Polymer Crystallization: Ordered Structures in Complex Systems"Abstract:The crystallization of long chain molecules requires two ordering processes which take place simultaneously: Transition of each chain from the randomly coiled state into the partially folded and extended state, and the growth of many chains forming a regular crystalline structure. This leads to complex crystallization and nucleation pathways which usually result in non-equilibrium meta-stable states.
