A continuous spectrophotometric procedure is presented for the measurement of the kinetic properties of acetylcholinesterase (EC 3.1.1.7) with its natural substrate, acetylcholine. The procedure is based upon the production of stoichiometric quantities of H+ upon hydrolysis of substrate.

Exact Asymptotic Relaxation of Pseudo-First-Order Reversible Reactions
Physical Review Letters, 1997The relaxation kinetics of the diffusion-influenced reversible reaction $A+B\ensuremath{\rightleftharpoons}C$ is studied in the pseudo-first-order limit $([B]\ensuremath{\gg}[A])$ when A and C are static and the B's move independently with diffusion coefficient D. For the initial condition $[A(0)]\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1$, $[

Simulation of 1,3-dichloropropene in topsoil with pseudo first-order kinetics
Journal of Contaminant Hydrology, 1995Abstract For fast-degraded chemicals such as 1,3-dichloropropane (1,3-D), their long persistent time in topsoils cannot be explained by the ordinary first-order kinetics of biodegradation that is commonly used in the simulation of chemical transport in soils.

Enhanced Kinetics of Pseudo First-Order Hydrolysis in Liquid Phase Coexistent with Ice
The Journal of Physical Chemistry A, 2013The reaction rate of the hydrolysis of fluorescein diacetate (FDA) is several times larger in the frozen state than that in the unfrozen solution of the same composition at the same temperature. The freeze concentration of reactants in the liquid phase expelled form ice crystals cannot explain the kinetic enhancement of pseudo first order reactions ...

Pseudo First-Order Adsorption Kinetics of N719 Dye on TiO2 Surface
ACS Applied Materials & Interfaces, 2011We have investigated the adsorption kinetics of Ru-based N719 dye on TiO(2) surface in dye-sensitized solar cell using 0.5 mM and 5 mM dye solutions. The amount of adsorbed dye on TiO(2) surface of ca. 5 μm-thick film was measured as a function of immersion (adsorption) time.

Pseudo-first-order phase transitions in one dimension
Journal of Physics A: Mathematical and General, 1979A study is made of the one-dimensional Ginzburg-Landau system with a cubic term, a model of the first-order phase transition. Fluctuations are taken into account by means of the WKB method. It is pointed out that the transition is of continuous type for any value of the coefficient of the cubic term.

The study of bimolecular reactions under non-pseudo-first order conditions
Biophysical Chemistry, 2005In this work a new equation which describes the time evolution of bimolecular reactions is derived and tested by experiment. The equation is general and the results show that second-order reactions of any simple type may be accurately described by a quotient of exponential functions. The model and reagent concentration dependent observed rate constants
