PL decay dynamics in solution are best described by a monoexponential function with a lifetime of 0.76 ns.
In this study, the contrast agents were introduced into solutions of different oxygen concentration levels, as might be encountered in blood, and their relative performance was assessed in terms of decay in the solution environment.
Because DMPO OH decays faster in solution, we conclude that the surface-stabilized DMPO OH adducts are responsible for the longer incubation times.
The decay of ReP− in solution, in the presence of CO2, has a strong biphasic behaviour, with a fast component in the 1 10 ms timescale and a slow phase in the 100 ms–1 s timescale, indicative of a multiple step process.
Consequently, CpdA dissolved in water is relatively stable while it rapidly decays in buffered solution with increasing pH.
The aim of this study was to evaluate the influence of the physical chemical characteristics of wastewater on PAA decay, in multi-component solutions of inorganic and organic compounds (11 compounds in total) representative of secondary effluents of wastewater treatment plants, disinfected at various PAA concentrations (2 5 mg/L).
Temperature dependencies of proton magnetic relaxation times and forms of transversal magnetisation decay in chloroform-d solutions of three liquid crystalline polyesters with fumaroil-bis-oxybenzoate mesogenic units connected by different flexible spacers (CH2 5, (CH2 6 and CH2(CH2CH2O2)2CH2 (poly R-M5), poly R-M5) and poly R-M62), respoly R-M6) and studied in the concentration range 9–20 w/w%.
From the biphasic transient absorption decay under CO2 of RePpic in solution, the kinetics of the slow phase are very similar to those of RePpic TiO2, suggesting that they involve the same process.
For the radiative and reactive gas, Ducomet [11] established the global existence and exponential decay in H1 of smooth solutions, and Umehara and Tani [12] proved the global existence of smooth solutions for a self-gravitating radiative and reactive gas.
If G 1 < 1 then solutions decay in both n and t, but this tells us nothing about the mean etching rate.
