Acidic dissolution of transition metals from Pt based alloy catalysts for oxygen reduction reaction (ORR) is an unavoidable process during fuel cell operation. In this work we studied the effect acid treatment graphene-supported Pt1Nix(x = 0, 0.25, 0.5, 1, and 2) alloys on kinetics ORR in both alkaline acidic solutions together with generation OH radicals solutions. The nanoparticles were synthesized through coimpregnation chemical reduction. electronic structural features characterized by...
A reusable sensing strategy employing magnetic nanoparticles and thymine-containing aptamers was developed to detect Hg2+ in real water samples based on "turn-on" resonance light scattering. The LOD as low 500 fM (S/N = 3), the present sensor can be repeatedly used for at least seven cycles.
A dependence of oxygen reduction reaction activity and generation OH radicals upon the composition Pt–Co alloy electrocatalyst supported on graphene was found in alkaline solutions.
Using photocatalytic reactive nanoparticles and DNA composite modified gold electrodes, exploiting the sensitivity of DNA-mediated electron transfer to base pair stacking, we examined effects oxidation damage by photocatalytically generated hydroxyl radicals (˙OH) on charge efficiency proposed an electrochemical technique read effective diffusing distance ˙OH.
In this study, a gold nanoparticles colorimetric probe (AuNPs) with direct response to mercury ions (Hg2+) were developed using treated N-methylpyrrolidone (NMP) and chloroauric acid (HAuCl4) as precursors. NMP showed good reducibility after high temperature hydrolysis could be used reducing stabilizing agent synthesize AuNPs. The prepared AuNPs have obvious characteristic absorption peaks appear wine-red. At the same time, it was found that presence of Hg2+ can cause aggregation AuNPs,...
N-doped carbon dots (NCDs) exhibit bright blue emissions and have been used as viable fluorescent probes in the turn-off fluorometric assay for vanillin detection. NCDs were prepared from glucose tyrosine using a facile green synthesis process. The one-pot hydrothermal treatment was without any strong acid or oxidant. fluorescence of (with excitation/emission peaks at 323/416 nm, respectively) can be quenched by vanillin. quenching mechanism belongs to dynamic mode due molecular collisions...
The mechanism of the interaction between bovine serum albumin (BSA) and ceftriaxone with without zinc (II) (Zn 2+ ) was studied employing fluorescence, ultraviolet (UV) absorption, circular dichroism (CD), synchronous fluorescence spectral methods. intrinsic BSA quenched by in a static quenching mode, which authenticated Stern-Volmer calculations. binding constant, number sites, thermodynamic parameters were obtained, indicated spontaneous hydrophobic regardless Zn . Changes UV CD, data are...
