Release of compositional elements and detection of illite, siderite and silica as reduction products during ESHA-mediated bioreduction of NAu-2 was in support of the dissolution-precipitation mechanism. Transformation of smectite to illite (S-I reaction) has long been recognized as an important ...
Scheme 2. Proposed sensing mechanism of 1 for Fe3 +. 3.4. Application in cellular imaging The toxicity of 1 is a natural concern because of its potential application for bioimaging. The cytotoxicity of 1 was evaluated by standard 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide ...

A 23factorial design of experiment was used to investigate the effect of synthesis parameters such as temperature, pH and volume of AgNO3to KI extract, while the result is shown in Table2c. According to Table2c, optimum formation of KIAgNPs at the wavelength of 450 nm was obtained at the ...
The possible formation mechanism of HEPES-coated Fe3O4 nanomaterials was also discussed. In the reaction system, the influence of inorganic anions on the morphologies of Fe3O4 nanostructures was also investigated. The as-synthesized spherical Fe3O4 nanoparticles with a concentration of 5–100 μg...

2.2.2. Hydration of Nitriles to Amides The reaction of benzonitrile in water was chosen as the test model. A possible mechanism of nitrile hydration by Ag catalyst is shown by Satsuma's group [28]. Almost no reaction occurred in the absence of a catalyst (entry 1, Table 3). Generally,...
Complexation Mechanism of SQ–Fe3+ and SQ–Hg2+ Job's plot measurement was carried out to determine the complexation mode between SQ and Fe3+. A maximum value of the absorption intensity at 525 nm was observed when the mole fraction of Fe3+ reached 0.5. A signature of 1:1 stoichiometry...
Visible-light-sensitive Ag/AgCl/SrTiO3 photocatalysts have been successfully assembled through the precipitation reaction between AgNO3 and NaCl at ambient temperature, wherein Ag/AgCl nanoparticles were immobilized on the surface of SrTiO3. The composition, crystallinity, morphologies and optical properties...
