Static Local Field Factor for Dielectric Screening Function of Electron Gas at Metallic and Lower Densities
A simple parametric form for the static local field factor G(q) which appears in the dielectric screening theory of an electron gas is proposed. A very accurate fit of Ceperley–Alder data of electron…

Dynamic insight into protein structure utilizing red edge excitation shift.
TLDR
While application of REES to proteins in native conformation has been in use for a long time, this work highlights the potential of this approach in case of molten globule and denatured conformations and demonstrates the presence of residual structure, that could not be detected using other methods, by REES ofDenatured spectrin.

Orientation and dynamics of a novel fluorescent cholesterol analogue in membranes of varying phase.
TLDR
Monitoring the orientation and dynamics of a novel fluorescent cholesterol probe, 6-dansylcholestanol (DChol), in membranes of different phase type utilizing sensitive fluorescence techniques including the red-edge excitation shift (REES) approach shows that fluorescence emission maximum, anisotropy, and lifetime of DChol are dependent on the phase of the membrane.

Organization and dynamics of membrane probes and proteins utilizing the red edge excitation shift.
TLDR
The red edge excitation shift (REES) represents a sensitive approach to monitor the environment and dynamics around a fluorophore in a host assembly to monitor organization and dynamics of membrane probes and proteins.

Photophysical behaviour of 1-(4-N,N-dimethylaminophenylethynyl)pyrene (DMAPEPy) in homogeneous media.
TLDR
The photophysical behaviour of a new pyrene derivative, 1-(4-N,N-dimethylaminophenylethynyl)pyrene (DMAPEPy), in various solvents has been studied and shows high steady-state fluorescence anisotropy, which is very sensitive to the viscosity change of the medium.
