"How defects become useful: the memory of confined nematic liquid crystals"

Abstract:
Nematic liquid crystals (NLCs) are uniaxial anisotropic and birefringent fluids that have been widely used for many decades in displays. While the aim of conventional display technology is to obtain a wholly aligned and defect-free material, new technologies are starting to exploit the potential of topological defects, i.e. regions where the NLCs are not aligned. ...

" Biology within Membranes: Solid and Solution State NMR approaches"

Abstract:
Cellular membranes define the space of numerous biological processes, including structure, transport, and signaling processes. One of the emerging tools for characterization of structure and function of membrane proteins is solid-state NMR, which has particularly been benefiting from fast spinning enabling manifold conceptually new techniques. Likewise, in the solution state, lipid-nanodisc techniques provide immaculate mimics of membranes new to NMR...

"PROTON SPIN KINETICS IN POLYMER MELTS: new perspectives for experimental investigations of polymer dynamics in bulk and confinement"

Abstract:
An essential progress was made in recent years [1-9] in understanding of the proton spin kinetics in polymer melts. This opens new perspectives for experimental investigations of polymer dynamics on the basis of different NMR methods. Generally, the proton spin kinetics is determined by intramolecular and intermolecular magnetic dipole-dipole contributions of proton spins. During many decades it was actually postulated that main contribution is coming from magnetic dipole-dipole interactions from intramolecular protons belonging to the same polymer segment. It appears that this postulate is very far from reality....

" Persistent correlations in complex Transport – Brownian motion and beyond"


Abstract: The pillars of all transport processes have been established in the molecular-kinetic interpretation of diffusion by Einstein and Smoluchowski. In modern terms the central limit theorem applies whenever dynamical correlations decay quickly. Yet, already the preeiminent dutch physicist Hendrik Antoon Lorentz noted that this theoretical framework fails to account for subtle effects in Brownian motion and has to be completed. In the presentation I will introduce several model systems where persistent correlations emerge with macroscopic measurable consequences...

“Optimization of Macromolecular Architecture in Styrene/Diene Block Copolymer Thermoplastic Elastomers"

Abstract:
Thermoplastic elastomers (TPEs) are rubbery materials that can undergo large reversible deformation. Unlike conventional crosslinked rubber, TPEs do not require chemical crosslinking, which gives advantages of lower processing costs and easy recycling. Conventional styrene/diene TPEs, for example Kraton® - a product of Kraton Polymers and a major commercial product, have changed little since their discovery 50 years ago by Shell Oil Company....

" Amyloid Fibrils: Certain Molecular Level Structural Insights with Solid-State Nuclear Magnetic Resonance. "

Abstract:

Ab peptides are interesting models for investigating different aspects of amyloid aggregation. On the basis of amyloid cascade hypothesis, which has dominated amyloid disease research for the past two decades, the main therapeutic strategies have aimed either to prevent the aggregation of Ab, or to remove toxic oligomeric and fibrillar species of Ab. Since Ab is ordinarily produced in the brain, and there is no proof that Ab overproduction underlies sporadic AD, the pursuit of former strategy demands a thorough understanding of all the neurochemical factors that initiate Aβ deposition in brain....

"Relaxation of Macromolecules Adsorbed on Surfaces Studied by Neutron Scattering Experiments"

Abstract:
Polymer based nanostructured materials promise substantially improved features such as increased tensile strength, abrasion resistance, and gas barrier tightness. Even composites with very different material behavior such as an enhanced electrical conductivity or the opposite way around better insulating properties can be assembled. Though intense research in this field has led to substantial progress toward the physical understanding ...

“Adsorption and folding transitions of a polymer chain: Applications of the Wang-Landau and partition function zeros methods"

Abstract:
The Wang-Landau (WL) algorithm is a Monte Carlo simulation technique providing a direct computation of the density of states (and thus the partition function) of a many-body system. The partition function encodes all thermodynamic information about a system, and thus, its construction allows for an efficient determination of phase behavior...

“Liquid-crystalline ordering in semiflexible polymer blends"

Abstract:
Semiflexible polymers of sufficient stiffness exhibit liquid crystalline order at low temperature and high polymer concentration. Blends of stiff and flexible polymers have interesting physical properties and important applications in organic electronics. For example, in bulk heterojunction devices, amorphous and ordered regions with varying compositions coexist due to microphase separation of the blend components. Accounting for these effects in device simulations is difficult ...
