“…In fact, with the presence of the above modifiers, the kinetics of electron transfer on the electrode has increased and this reduces the load transfer resistance. In the case of the modified Fe 3 O 4 @SiO 2 -NH 2 /CS 2 electrode, there is a very sharp increase in charge transfer, which can be related to the high conductivity of the modifier [42][43][44][45][46].…”

Azaperone is a very important phenylbutanone-based neurotransmitter used in the treatment of some animal (veterinary) clinics. This compound has various nerve and tendon stabilizing agents on livestock and animals. Muscular injection of azaperone is used to reduce stress in livestock and reduce their acting. In the present work, Fe3O4@SiO2-NH2/CS2 nanocomposite was synthesized and thoroughly characterized using FE-SEM, FT-IR, and XRD technique. The glassy carbon electrode was then modified with nanocomposite to fabricate a sensor named GCE/Fe3O4@SiO2-NH2/CS2. The application of modified electrode was tested for analysis of azaperone in ostrich meat and rat plasma. The electrochemical behavior of azaperone was tested using differential pulse and cyclic voltammetry. In Briton–Robinson buffer solution (pH = 6), azaperone had an oxidation peak at 0.82 V. Cyclic voltammetry studies indicated that the azaprone oxidation process on the modified electrode is irreversible. Experimental variables, including pH and accumulation time were optimized by monitoring the cyclic voltammetry responses toward azaperone peak current. Measurement of azaperone by differential pulse voltammetry technique showed linearity of anodic peak current vs. azaperone concentration in a range of 0.01–100.0 μM with detection and quantification limits of 3 nM and 10 nM, respectively. Also, the effect of disturbance of some species as possible interferers on the electrochemical response of azaperone was checked out. Finally, the capability of the fabricated sensor for azaperone measurement was successfully tested in ostrich meat and rat plasma as real samples. Graphical abstract

“…The electrochemical impedance spectrometer (EIS) method was used to evaluate the charge transfer impedance [31][32][33] of prepared electrodes in a 8.0 g l -1 Na SO 2 4 solution in the frequency range of 10 -1 -10 5 Hz. The arc diameter of the Nyquist diagram (figure 4) is directly related to the charge-transfer impedances.…”

Today, electrochemical methods and their applications in human life, combating environmental pollution, synthesis and energy have been taken scientists' attention. Meanwhile, the preparation of various compounds and products using electrochemical methods has received more attention due to various advantages such as ease and low cost. Here, we used an electrochemical method to prepare perchlorate. Perchlorate salts are extensively used in rocket fuel, spacecraft, submarines, airbags, fireworks, and fertilizers. Since the anode potential for perchlorate oxidation is near that for water oxidation, conventional electrodes can't be used in the perchlorate electrosynthesis. The modified PbO2 electrodes by neodymium with a wide potential window can be used for this purpose. We prepared these electrodes and they were first evaluated by scanning electron microscopy (SEM), X-ray diffraction (XRD) spectrometer, voltammetry and electrochemical impedance spectrometer (EIS). The results showed that the potential of water oxidation on the modified PbO2 electrodes by neodymium was 2 V. To achieve high production yield in the preparation of perchlorate from chlorate, various parameters including pH, time, and current density were optimized by the Box-Behnken design of the experiment method. The optimal values for this process were obtained at pH = 11, temperature 40C and current density of 0.5 mA/cm2. The results at the optimal condition showed that the perchlorate production yield by modified PbO2 electrodes was 80% in the 300 min. This value was only 60% for the unmodified PbO2 electrode.

At present, nanostructures with excellent morphology have become a research hotspot. With the deepening of research and the rapid development of nanotechnology, nanosemiconductors have also made remarkable progress. In recent years, ZnWO4 in metal tungstates has been widely used in many fields, which is mainly due to its high crystal density, short radiation length, excellent optical properties, good radiation damage resistance, and non‐liquefaction. Therefore, herein, the synthesis methods and applications of ZnWO4 semiconductor materials in recent years are reviewed. First, the crystal structure and characteristics of ZnWO4 are described, and then the latest research progress of ZnWO4 semiconductor materials is summarized. The synthesis methods and contributions to photocatalysis, sensors, electronic materials, and luminescent materials are highlighted. The characteristics of ZnWO4 nanoarrays and their applications in supercapacitors are particularly emphasized, which provide a reference for the development of multifunctional nanoarrays. Finally, the challenges and countermeasures of ZnWO4 semiconductor materials are summarized and prospected. In a word, a new idea and strategy to design and assemble new types of ZnWO4 nanomaterials with multiconstructional systems and multifunctional properties for their practical applications is provided.
