Then, carbaryl was hydrolyzed into reductive 1-naphthol in alkaline condition, which directly decomposed β-MnO2 into Mn2+ and significantly hindered the β-MnO2/Ni2+-mediated production of triOPD-Ni2+ polymers. Consequently, the photothermal effect was linearly correlated with carbaryl concentration ...

silica gel column chromatography and preparative liquid chromatography, and their structures were identified by NMR, MS and other spectra data. Results: One compound was isolated from medicinal materials Xianzhuli and elucidated as 5-(4-hydroxy-3,5-dimethoxyphenyl)-2,4-dimethoxy-3-naphthol. ...
An enzyme inhibition-based lab-in-a-syringe (EI-LIS) device was developed by integrating a 1-naphthol-linked bi-enzymatic reaction (sensor core) into the LIS (sensor device) for point-of-need monitoring of pesticide residues. The integration relies on the rational design of two reaction pads...
In this work, we investigate the influence of water molecules attached to naphthol on the spectroscopic properties of the neutral excited-state S1 and the ionic state. In addition to S1←S0 spectra, we present mass-analyzed threshold ionization (MATI) spectra for 1-naphthol and for the first ...

The pH optima in the presence of ABTS, α-naphthol, o-dianisidine, and catechol were 4.5 but 5.0 and 5.5 in the presence of guaiacol and pyrogallol, respectively. The initial velocities obtained from the kinetic study were analyzed using Graph Pad Prism 7 and Lineweaver-Burk plot to obtain ...
