Relaxation phenomena during non-equilibrium growth
… by a power-law or by an exponential relaxation, are identified, and a dynamic phase diagram is constructed. We discuss global fluctuation-dissipation ratios and how to use them for the characterization of non-equilibrium growth processes. We also numerically study the same two-time …

Relaxation dynamics in heme proteins
… to give rise to a multitude of nonequilibrium relaxation phenomena. If the temperature is lowered, transitions between substates of higher tiers are frozen out, and relaxation processes characteristic of lower tiers will dominate the observational time scale.

Detection and characterisation of secondary relaxations in solids using thermally stimulated current spectroscopy
… the detection and characterisation of secondary relaxation phenomena in the crystalline state for a number of low-molecular weight organic materials (LOMs), namely α-alanine, β-alanine, a co-crystal system (salicylic acid and benzamide) and the drug paracetamol (form I). The aim of the research …

Understanding The Physics Of Magnetic Nanoparticles And Their Applications In The Biomedical Field
… by these materials. Two of the most important relaxation phenomena occurring in magnetic nanoparticles are superparamagnetic blocking and spin-glass-like freezing. In addition to features attributed to superparamagnetism, these nanoparticles can also exhibit magnetic relaxation effects at very …

Asymptotic and numerical analysis of time-dependent wave propagation in dispersive dielectric media that exhibit fractional relaxation
… the non-exponential nature of such dielectric relaxation phenomena, which is manifest in a variety of dispersive dielectric media. In the C-C model, the dielectric polarization is coupled to the time-dependent Maxwell's equations by a fractional differential equation involving the electric …

Shock Physics in Compressible Solids
… (TVE) materials with and without rheology. Shock phenomena in compressible solids are inherently complex, involving nonlinear wave interactions, dissipation mechanisms, and material-specific properties. Through the development of mathematical models, numerical methods, and detailed model problem …

Temperature-dependent Terahertz Time-domain Spectroscopy as a Tool to Assess the Crystallisation Tendencies of Amorphous Drug-Polymer Systems
… as polymer grade and drug loading, influence relaxation dynamics and the crystallisation tendency of ASDs. ASDs of three model drugs – indomethacin, felodipine, and clotrimazole – were prepared with the polymer HPMCAS across a range of drug loadings and polymer substitution grades. …

Influence Of Cholesterol And Bilayer Asymmetry On Membrane Protein Distribution In Polymer-Tethered Raft-Mimicking Lipid Membranes
… stress by inducing membrane buckling, a stress relaxation phenomena. As part of the current dissertation, we established that membrane buckling can also be induced by gradually increasing CHOL concentration in polymer-tethered membranes of low lipopolymer content. Further analysis using …

Primary and Secondary Relaxations in Neat and Binary Glass Formers Studied by Means of Dielectric Spectroscopy
… temperature evolution of primary and secondary relaxation phenomena. The other objective is to gain insight into the microscopic origin of the beta-process (a secondary relaxation observed for T<Tg) in neat and binary systems, as well as the primary relaxation phenomena in binary systems. The …
