Time-resolved studies of radical pairs

Biochemical Society Transactions, 2009
The effect of magnetic fields on chemical reactions through the RP (radical pair) mechanism is well established, but there are few examples, in the literature, of biological reactions that proceed through RP intermediates and show magnetic field-sensitivity. The present and future relevance of magnetic field effects in biological reactions is discussed.

Time-Resolved Fluorescence Studies of Fullerene Derivatives

The Journal of Physical Chemistry B, 2013
Fullerene (nano-C60) and its water-soluble derivatives have several clinical applications including use as a drug carrier to bypass the blood-ocular and blood-brain barriers. However, in vitro and in vivo detection of these nanomaterials is limited by their very low fluorescence quantum yield.

Time-resolved photoluminescence studies of biexcitons in InP

Physical Review B, 1993
The low-temperature (5 K), steady-state photoluminescence spectra of a high-quality InP sample grown by chemical-beam epitaxy, reveal a new emission band at high excitation intensities. This emission is characterized by a superlinear intensity dependence on excitation density, a lifetime shorter than that of the polariton, and an energy between those ...

Time-resolved structural study of Pb(100)

Physical Review Letters, 1993
Time-resolved reflection high-energy electron diffraction is used to study the structural behavior of Pb(100) subjected to 200 ps laser pulses. Analysis of the electron diffraction intensity indicates that residual order is present on the surface at a temperature of 615[plus minus]20 K, where the bulk melting temperature of Pb is 600.7 K.

A Time-Resolved Spectroscopic Study on Peptide Folding

2010
Generation of nucleation centers, such as the helix-turn-helix motif, is one of the possible mechanisms of protein folding. Therefore, knowledge of the kinetics of formation of such locally structured domains may be important for discriminating different folding pathways.

Time-resolved studies of solvation

AIP Conference Proceedings, 1988
Solvent dynamics in alcohols are measured by examining the time dependent Stokes shift of the emission from the twisted intramolecular charge transfer state of bis(4‐(dimethylamino)phenyl) sulphone (DMAPS). The solvation times deviate from the dielectric continuum prediction of τL, the longitudinal relaxation time of the solvent, but generally fall ...
