Pseudomonas putida HS12, which is able to grow on nitrobenzene, was found to carry two plasmids, pNB1 and pNB2. The activity assay experiments of wild-type HS12(pNB1 and pNB2), a spontaneous mutant HS121(pNB2), and a cured derivative HS124(pNB1) demonstrated that the catabolic genes coding for the nitrobenzene-degrading enzymes, designated nbz, are located on two plasmids, pNB1 and pNB2. The ge...

A single crystal of organic nonlinear optical material 3-aminophenol perchlorate (3-AMP) was successfully grown by the slow evaporation solution method. Single-crystal X-ray diffractrometer was utilized to measure unit cell parameters and to confirm lattice parameter. 3-aminophenol perchlorate belongs to monoclinic space group P21. The optical transparency window in the UV–vis-NIR region is fou...

The experimental arrangement in this investigation is one in which poly(o-aminophenol) (POAP) films were supported on thin gold films. Freshly prepared POAP film electrodes were firstly deactivated by interaction with a ferric cation solution and then, they were reactivated by treatment with an alkaline solution. Cyclic Voltammetry (CV) and Surface Resistance (SR) measurements were performed to...

The capillary electromigration method is an important analytical technique known for its simplicity, sensitivity, and selectivity. We have investigated electrophoretically mediated microanalysis (EMMA) in plug-plug and continuous formats for the determination of phenolic compounds. The azocoupling reactions of phenol, 3-aminophenol, and resorcinol with 4nitrophenyldiazonium fluoroborate were ca...

Dopamine (DA) is a neurotransmitter, and its levels in the human body are associated with serious diseases. The need for suitable detection method medical practice has encouraged development of electrochemical sensors that take advantage DA electroactivity. Molecularly imprinted polymers (MIPs) biomimetic materials able to selectively recognize target analytes. A novel MIP sensor proposed here ...

In this research, a facile and effective approach was developed for the preparation of well-designed AuPd alloyed catalysts supported on magnetic halloysite nanotubes (HNTs@Fe₃O₄@AuPd). The microstructure and the magnetic properties of HNTs@Fe₃O₄@AuPd were confirmed by transmission electron microscopy (TEM), high resolution TEM (HRTEM), energy-dispersive X-ray spectroscopy (EDS), and vibrating ...

This work reports the reduction of 4-nitrophenol to 4-aminophenol using UiO-66(Zr) as a bifunctional photocatalyst and hydrogenation catalyst methanol hydrogen source.
