The influence of variation of concentration of ACOP and AD was investigated at BiVO<sub>4</sub>/NaOH/MCPE. The limit of detection (LOD) and limit of quantification (LOQ) of both ACOP and AD at BiVO<sub>4</sub>/NaOH/MCPE, respectively were determined, the LOD was found to be 3.3 µM for ACOP and 5.9 μM for AD, and LOQ was found to be 11.1 µM for ACOP and 17.8 μM for AD, respectively. Moreover, the BiVO<sub>4</sub>/NaOH/MCPE is used for the sensitive and selective determination of ACOP and AD in real samples.https://www.abechem.com/article_705133_54d6edd0f2634d3b1b62280e1a40ba89.pdfAnalytical and Bioanalytical Electrochemistry is an international scientific journal, which is published online every 3 months (since 2009), every 2 months (since 2011) and monthly (since 2018) by Center of Excellence in Electrochemistry, University of TehranAnalytical and Bioanalytical Electrochemistry-15520230531Voltammetric Determination of Trace Methyl Parathion using Electrochemically Reduced Graphene Oxide Modified Carbon Screen-Printed Electrodes35637070513410.22034/abec.2023.705134ENHesameddin AzimiDepartment of Civil and Environmental Engineering, University of Massachusetts Lowell, Lowell, MA, USAConnor SullivanDepartment of Civil and Environmental Engineering, University of Massachusetts Lowell, Lowell, MA, USADingnan LuDepartment of Civil and Environmental Engineering, Ningbo University, Zhejiang, ChinaEric BrackU.S. Army Natick Soldier Systems Center, Natick, MA, USAChristopher DrewU.S. Army Natick Soldier Systems Center, Natick, MA, USAPradeep KurupDepartment of Civil and Environmental Engineering, University of Massachusetts Lowell, Lowell, MA, USA0000-0001-9605-7199Journal Article20230114Timely, efficient on-site detection of pesticides such as methyl parathion (MP) is crucial to ensure public health. This study introduces the first disposable electrochemically reduced graphene oxide (ErGO) modified electrode for rapid MP detection. A square wave anodic stripping voltammetry method for the detection of MP was developed using these ErGO-modified carbon screen-printed electrodes. Based on this study, graphene’s high electric conductivity and unique structure enhanced the sensitivity of the electrode for MP detection. Following optimization of the pH, equilibrium period, deposition potential, and period, the methodology demonstrated high sensitivity and reproducibility. Using the enhanced experiment conditions, calibration experiments were performed with a concentration range of 0 to 150 µg L<sup>-1</sup> of MP. A consistent oxidation peak was observed at -0.180 V. The calibration data showed the increase in the peak height was linearly correlated to the increase in MP concentration, with a correlation coefficient of 0.9854. The sensitivity of the developed methodology was 0.0887 µA (µg L<sup>-1</sup>)<sup>-1</sup>, and the limit of detection was 9.06 µg L<sup>-1</sup>.

Ni-based compounds to which solid Al<sub>2</sub>O<sub>3</sub> particles have been electrochemically inserted. Nickel-alumina mixtures were deposited on steel substrates from the electroplating bath using different concentrations of Al<sub>2</sub>O<sub>3</sub>. The electrochemical corrosion tests of the samples were carried out in two different solutions 0.5 M K<sub>2</sub>SO<sub>4</sub> and 0.5 M NaCl. Structural and morphological analyzes were carried out by X-ray diffraction (XRD) and scanning electron microscopy (SEM) coupled to microanalysis (EDAX) analyses respectively. The electrochemical behavior of co-electrodeposited coatings (Ni-Al<sub>2</sub>O<sub>3</sub>) in corrosive solutions was followed using potentiodynamic methods and electrochemical impedance spectroscopy (EIS). The various tests carried out under working conditions revealed that the Al<sub>2</sub>O<sub>3</sub> particles added to the bath have a beneficial effect on the electrochemical behavior of the steel by reducing its tendency to corrosion. In this work, we were also able to determine the optimal concentration leading to significant inhibition of the steel tested.

(EEH) seeds with different oxidation potentials was confirmed by cyclic voltammetry. The evaluation of the inhibition efficiency of the extract on zinc corrosion in the hydrochloric acid medium was carried out by gravimetry and electrochemical techniques. The results showed that the extract has satisfactory corrosion-inhibiting properties and that its efficiency is controlled by its concentration and medium temperature. The inhibition rate reached 96.8% in the presence of 2200 ppm of the EEH extract at 298K. The potentiodynamic polarization study showed that the extract is classified as a mixed-type inhibitor with a cathodic predominance. A good agreement between the results of the gravimetric study and those of the electrochemical measurements was demonstrated. The studied extract acts by physical adsorption, as indicated by the thermodynamic parameters, and follows the Langmuir model. The inhibition efficiency of the studied extract was improved in the presence of KI through a synergistic effect.https://www.abechem.com/article_705137_da8d7510185d6eae7d111bbbc92e057c.pdfAnalytical and Bioanalytical Electrochemistry is an international scientific journal, which is published online every 3 months (since 2009), every 2 months (since 2011) and monthly (since 2018) by Center of Excellence in Electrochemistry, University of TehranAnalytical and Bioanalytical Electrochemistry-15520230531Electrochemical Determination of Human Growth Hormone (HGH) Utilizing A Pyrrole (Py) Molecularly Imprinted Polymer (MIP) On Screen-Printed Carbon Electrode (SPCE)41042770513810.22034/abec.2023.705138ENShahriar BohlooliDepartment of Biology, University of Guilan, Rasht, IranSolmaz KiaDepartment of Engineering Sciences, Faculty of Advanced Technologies, University of Mohaghegh Ardabili, Namin, IranShahab BohlooliDepartment of Pharmacology, School of Pharmacy, Ardabil University of Medical Sciences, Ardabil, IranReyhaneh SaririDepartment of Biology, University of Guilan, Rasht, IranJournal Article20230108A new electrochemical biosensor based on Fe<sub>3</sub>O<sub>4</sub> nanoparticles and molecularly imprinted polymer-modified screen-printed carbon electrode (SPCE) was built to record the HGH molecules. The HGH is an important metabolic hormone and is responsible for body growth, stimulating the growth and differentiation of muscle, bone, and cartilage. A stable SPCE/Fe3O4/Poly-pyrrole/MIP layer was formed by the electro-polymerization of pyrrole molecules as functional monomers and HGH as template molecules. The accuracy and sensitivity of the prepared SPCE were confirmed using the electrochemical impedance spectroscopy (EIS) technique. According to the results, the MIP showed a linear range of 1×<br />10<sup>-6</sup> to 1×10<sup>-11</sup> g/cm<sup>3 </sup>for the HGH under study conditions with a limit of detection (LOD) of 2.927×10<sup>-12</sup> g/cm<sup>3</sup>. The calibration curve showed 99.9% correlation of the data. It can be concluded that the MIP made for HGH molecules has high sensitivity and stability, low cost, short response time, and excellent reproducibility.https://www.abechem.com/article_705138_ca16d82a5ae974bd73bdcca8c51a4d3d.pdf
