Chemical Physics, 1992 Abstract A theory for describing the effects of static quenching in the diffusion-influenced fluorescence quenching is presented, which is based on a hierarchical system of many-body Smoluchowski equations for the reactant molecule distribution functions.

Static Approach to Renormalization Group Analysis of Stochastic Models with Spatially Quenched Noise [PDF]
Journal of Statistical Physics, 2019 A new ''static'' renormalization group approach to stochastic models of fluctuating surfaces with spatially quenched noise is proposed in which only time-independent quantities are involved. As examples, quenched versions of the Kardar-Parisi-Zhang model and its Pavlik's modification, the Hwa-Kardar model of self-organized criticality, and Pastor ...

Dynamic and static quenching of 2-aminopurine fluorescence by the natural DNA nucleotides in solution [PDF]
Methods and Applications in Fluorescence, 2020 Abstract 2-aminopurine (2AP) is a responsive fluorescent base analogue that is used widely as a probe of the local molecular environment in DNA. The ability of 2AP to report changes in local conformation and base-stacking interactions arises from the efficient quenching of its fluorescence by the natural DNA bases. However, the mechanism

Characterizing the photoluminescence of fluorescein-labeled cellulose in aqueous and alcohol solutions: influence of the cellulose backbone [PDF]
Scientific ReportsAlthough many dyes have been introduced into cellulose, whether bound to its backbone or within a cellulose matrix, few studies have determined whether the backbone statically or dynamically quenches the photoluminescence of the dye.

Effects of Efimov states on quench dynamics in a three-boson trapped system [PDF]
Physical Review A 106, 063316 (2022), 2022 We investigate the effects of Efimov states on the post-quench dynamics of a system of three identical bosons with contact interactions, in a spherically-symmetric three-dimensional harmonic trap, which undergoes a quench in interaction strength. Using known hyperspherical solutions to the static three-body problem we calculate semi-analytic results ...

Study on the fluorescence properties of the interaction between felodipine and bovine serum protein [PDF]
E3S Web of Conferences, 2021 The interaction between felodipine and bovine serum protein was studied, the optimal experimental conditions were selected, and the fluorescence quenching mechanism was discussed. The interaction between filodipine and bovine serum protein was determined

Molecules, 2023 Excited-state chemistry relies on the communication between molecules, making it a crucial aspect of the field. One important question that arises is whether intermolecular communication and its rate can be modified when a molecule is confined.
