Like other organophosphorus pesticides, this compound exhibits inhibitory effects on acetylcholinesterase enzyme. The inhibition of the enzyme leads to the accumulation of acetylcholine and causes the death of insects. DZN is considered a toxic compound for humans due to its high adsorption via skin and inhalation, which leads to the emergence of different symptoms of toxicity. When DZN is used for plants, the compound residues in crops enter the food chain, and hence, bring about different problems for human health. Moreover, the compound is easily washed by surface water and enters the groundwater. Its entrance into aquatic environments can negatively affect a wide range of non-targeted organisms. Thus, researchers are seeking to find fast and precise methods for the recognition of DZN. The electrochemical method for recognizing the compound in real samples is preferable to other analytical methods. Because this method can be used without spending time preparing the sample, it is simple, fast, and cost-effective. The present study is an overall review describing electrochemical-based methods for the recognition of DZN. Methods of modifying electrodes with CNT, polymers, biomolecules, and the simultaneous use of multiple methods are evaluated and compared. The influential factors contributing to the improvement of the signal response are also explained.","PeriodicalId":15660,"journal":{"name":"Journal of Electrochemical Science and Engineering","volume":"28 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76306276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, the effect of the nozzle distance and pulse number parameters were investigated on the modification process. AISI 4140 steel was preferred as the substrate for modification. In this system, the battery capacity and voltage were constant, and, were selected as 800 mF and 3000 V, respectively. The AISI 4140 steel samples were modified by applying 5, 10, and 15 pulses with 40, 50 and 60 mm nozzle distance. The molybdenum consumable electrode was used during the process. The modified surfaces were examined by optical and scanning electron microscope (SEM) and analyzed by X-ray diffractometer (XRD). Vickers microhardness on the cross-section surface of the samples was measured under a load of 50 g for 15 s. Finally, the specimens were exposed to corrosion in 0.5 M NaCl solution. Corrosion tests were realized using the potentiodynamic polarization method. A modified layer on the steel was determined to consist of two layers, the compound layer and the diffusion layer. It was observed that the structure and thickness of the modified layer affect by pulse number and nozzle distance. New phases such as Fe2N, FeN, MoN, and γ-Fe in the modified layer have occurred. The hardness value of the treated sample has risen about 4-5 times than the untreated, depending on applied process parameters. In general, the pulse plasma treatment has improved the corrosion resistance of treated samples. It was observed that while intergranular corrosion has formed on the unmodified surface, pitting corrosion has appeared on the unmodified surfaces.","PeriodicalId":15660,"journal":{"name":"Journal of Electrochemical Science and Engineering","volume":"21 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81533068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The physicochemical properties and characteristics of DES, namely, conductivity, FT-IR and NMR analysis were determined. FT-IR results confirmed that H-bonds occurring between two components in DES were the main force leading to the eutectic formation. Electrochemical techniques were used to characterize the deposition process and scanning electron microscopy was used to study the deposit morphology. Based on polarization measurements, it has been found that at NiCl2·6H2O content of 1.14 M and a temperature of 75 °C, the limiting current density of nickel electrodeposition was near 2 A dm-2. The polarization of the cathodic nickel deposition varied within -0.63 to 1.1 V at current density of 0.25 A dm-2 It has been shown that an increase of water content in the electrolyte does not significantly affect the current efficiency of the nickel electrodeposition process, which was in a range 85-93 %. However, the increase in water content contributes to the increase of heterogeneity and crystal grains size distribution of galvanic deposits. The established values of the Wagner number indicate the predominance of the primary current density distribution in the process of electrodeposition of nickel coatings. Galvanic coatings possess a highly developed nanostructured surface, exhibit increased capillary properties, and can be used as electrode materials for the process of electrolysis of water.","PeriodicalId":15660,"journal":{"name":"Journal of Electrochemical Science and Engineering","volume":"11 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86987171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used for structural and morphological analysis of the fabricated cathode materials, while charge-discharge curves and differential capacity were used to study the electrochemical behavior. Results confirm the formation of the structures with two phases associated with the components of the layered material. It was found that at 55 °C, a capacity higher than 357 mAh g-1 could be achieved at a voltage of 2.5-4.8 V vs. Li/Li+, which was larger than the capacity achieved at room temperature. At 55 °C, a change in valence could be observed during charging and discharging due to the change in the position of the peaks associated with Mn and Ni, highlighting cathodic material with x = 0.5 as the material that retains the layered structure at this temperature. This work confirms the good performance of electrodes made with this material at elevated temperatures and gives a better understanding of its electrochemical behavior.","PeriodicalId":15660,"journal":{"name":"Journal of Electrochemical Science and Engineering","volume":"2 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79256492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
