Relaxation kinetics of excitons in cuprous oxide
… luminescence reveals the relaxation of their kinetic energy distribution. It has been known for several years that, when the excitons are produced with the highest attainable densities, the time-sequence of exciton kinetic energy distributions closely resembles a sequence …

Infrared Studies of Intramolecular Rovibrational Relaxation (Kinetics, Energy Transfer)
… the extent of intramolecular vibrational relaxation from the CH stretching modes of several organic molecules. The molecules are isolated and cooled in a pulsed supersonic expansion. The infrared fluorescence is collected and dispersed using either a cryogenic Michelson interferometer or a …

Monte Carlo analysis of non-equilibrium steady states and relaxation kinetics in driven lattice gases
… we find that correlations induce extremely slow relaxation to the asymptotic power law decay We compare the crossover functions obtained from our simulations with various analytic results in the literature, and analyze the characteristic oscillations that occur in finite systems away from …

On the Relaxation Dynamics of Disordered Systems
… the steady-state properties and non-equilibrium relaxation kinetics of magnetic vortex lines in disordered type-II superconductors. To this end, we developed a versatile and efficient Langevin molecular dynamics simulation code, allowing us to do a careful study of samples with or without …

Analyses and predictions of ultrasound interactions with model biomembrane systems via two-state transition model
… employed to investigate biomembrane structural relaxation kinetics via absorption and velocity dispersion spectroscopy. The multilamellar vesicles utilized in this investigation were either composed of pure phospholipids or mixtures of phospholipids and small molar fractions of protein …

Nonequilibrium Relaxation and Aging Scaling Properties of the Coulomb Glass and Bose Glass
… scaling methods, we find that the nonequilibrium relaxation properties can be described sufficiently by a full-aging scaling analysis. The scaling exponents depend on both temperature and filling fraction, and are thus non-universal. We look at the trends of these exponents and found that as …

Optical study of shear and longitudinal acoustic waves and complex relaxation dynamics of glass forming liquids
… refined and used to study the complex structural relaxation dynamics of glass forming liquids, allowing both empirical modeling and testing of the predictions of the mode-coupling theory (MCT). Longitudinal and shear acoustic waves throughout much of the MHz frequency range, time-dependent thermal …

Nanoporous glass-ceramics transparent in infrared range to be used as optical sensor-Mechanical and viscoelastic properties of the TAS (Te-As-Se) glass
… an increase of tensile strength. The structural relaxation phenomenon is hypothesized to explain these results. The coordination number, , which is a rough measure of the network rigidity, has an influence on the TAS mechanical properties. It is shown that the TAS glass exhibits photosensitive …

Exercise induced damage to skeletal muscle and connective tissue
… day 3 post exercise. Unaltered contraction and relaxation kinetics suggested that the sarcoplasmic reticulum was not the site of E-C coupling delays. Prior 'conditioning' eccentric exercise bouts of varying duration were used to examine skeletal muscle adaptation to a subsequent bout of 50 …

Structural and contractile alterations in skeletal muscles from the genetically obese (ob/ob) mouse: impairment or adaptation?
… and tetanic force-generating capacity and kinetics; force-frequency relationship] of EDL, SM and SOL muscles from ob/ob and lean mice were explored using an isolated whole muscle preparation. The following statistically significant differences were observed for muscles from ob/ob mice when …

All Inorganic Colloidal Perovskite Nanocrystals for Optoelectronic Applications
… effect of surface traps on hot carrier cooling kinetics, making use of polar antisolvents to intentionally introduce surface traps in inorganic CsPbBrxI3x NCs. Through energy-dependent PLQY measurements, I observe the increased tendency of the hot carriers to localise in the trap states as their …
