Our results show that the effect of this ratio must be interpreted in combination with other environmental factors, such as the type and complexity of the electron donor, pH, or sulfide concentrations.
To minimize the blank rate with the more reactive donor, assays with p-Tol-SO2S– and glutathione are conducted at a pH (pH 8.0) and temperature (25 °C) lower than those of the standard TST assay with thiosulfate as the donor (pH 9.0 and 37 °C, respectively).
The hydrogenation reaction, studied with solution recycling through the HPM, was mainly influenced by the flow rate in the column, the excess of hydrogen donor, the pH of the solution and the type of acid used for pH control (poisoning effect of chloride ions), but was poorly influenced by temperature.
Though Eu III) prefers ionic binding with a strong acid ligand, it is also capable of weak binding with a neutral oxygen donor at pH 3 and 4. Sorption is affected by solution acidity despite the absence of ion exchange.
A multivariate design of experiments was used in which a half fractional factorial approach was applied to screen six factors (donor phase pH, acceptor phase HCl concentration, carrier composition, stirring rate, extraction time and salt content) for their extent of vitality in carrier mediated liquid microextractions.
Dataset 2 consists of all brain tissue samples with known donor brain pH and duration of agony stage contained in the database.
Therefore, acid-sensitive variants can serve as ideal donors in pH indicators based on FRET, and DsRed is the most desirable acceptor [ 110].
A linked donor-bridge-acceptor molecule, PZn-Ph-NDI, consisting of a (porphinato Zn donor (PZn), a phenyl bridge (Ph), and a naphthalene diimide acceptor (NDI), is shown to be a "meter" to indicate protein dielectric environment.
The biosynthesis of AgNPs is affected by a variety of factors (substrate concentration, electron donor, incubation time, pH, temperature, buffer strength, etc).
No evidences for the dependence of chip RNA quality on brain pH, donor age of death, duration of agony stage, and post-mortem interval before sampling was found.
This ratiometric chemosensor was constructed by introduction of a pH-insensitive coumarin fluorophore as an FRET donor into a pH-sensitive amino-naphthalimide derivative as the FRET acceptor.
