Static and Dynamic Quenching of Ru(II) Polypyridyl Excited States by Iodide
Inorganic Chemistry, 2005The metal-to-ligand charge-transfer (MLCT) excited states of Ru(bpy)(2)(deeb)(PF(6))(2), where bpy is 2,2-bipyridine and deeb is 4,4'-(CO(2)CH(2)CH(3))(2)-2,2'-bipyridine, in dichloromethane were found to be efficiently quenched by iodide at room temperature.

Biochemistry, 1985
The reactions catalyzed by argininosuccinate synthetase have been examined by the use of static and dynamic quench techniques. The time course of the forward reaction (22 degrees C) at pH 8.0 is characterized by a "burst" of AMP formation upon quenching with acid that is equivalent to 0.59 mol of enzyme.

Theoretical analysis of the static quenching of optical excitations in luminescent nanoparticles
JETP Letters, 2010A compact analytical expression has been obtained for the kinetics of the donor-acceptor transfer of the energy and the quenching of optical excitations in spherical nanoparticles with luminescent impurities. A series of numerical experiments simulating the process have been performed using the Monte Carlo method for nanoparticles of various sizes and ...

Significance of the static fluorescence quenching limit in the finite sink approximation
Journal of Photochemistry and Photobiology A: Chemistry, 1989Abstract In the finite sink approximation the time-independent quenching rate constant kQ(c) increases with quencher concentration c according to the equation where (2πNc)− 1 3 ) = r0, the most probable nearest-neighbor separation or sink radius.

Coordination Polymer Nanoarchitecture for Nitroaromatic Sensing by Static Quenching Mechanism
The Journal of Physical Chemistry C, 2015A nanoscale coordination-polymer (CP) architecture with a π-conjugated backbone (Zn-ata) was synthesized in this work. In aqueous media, this material exhibited a specific fluorescence response to nitroaromatics (detection limits of 0.2–1.3 ppm) but not to nitroaliphatics, despite their similar electron affinities.

Static solitary wave solution in 1D quantum quenched systems
Physics Letters A, 1985Abstract We use Morita's formulation to describe quenched systems. Through the Holstein-Primakoff (HP) representation we quantize the system in 1D and it gives coupled non-linear Schrodinger equations. We show that a static solitary wave is a solution of these equations.

Static fluorescence quenching in the study of micellar systems
2007The effect of a number of polar and non-polar organic molecules on the micelli- zation of sodium dodecyl sulfate at low suffactant and additive concentration, has been studied by fluorescence probing methods. The solubilization and its effect on micellar parameters and structure is examined and some general trends are discussed.

Static and dynamic fluorescence quenching of a dicyanoanthracene-capped β-cyclodextrin
J. Chem. Soc., Perkin Trans. 2, 1995Fluorescence quenching of 6A,6D(C)-(9, 10-dicyanoanthracene-2,6-disulfonyl)-β-cyclodextrin (DCA-β-CD) by several amines (1–6) has been investigated. Apparent Stern–Volmer constants, which are the sum of dynamic and static (binding) components, have been determined.

Instabilities of quasi-static crack patterns in quenched glass plates
Physica D: Nonlinear Phenomena, 1997Abstract We have produced controlled quasi-static crack propagation in thin glass plates to study crack instabilities. Quasi-static fractures can exhibit drastic changes in morphology when the control parameter is varied. The thermal stress and the velocity of the crack tip depend on the temperature difference between two heat reservoirs (ΔT) and the
