Polarography was first developed in the 1920 s in Czechoslovakian and Japanese laboratories, where the foundations of the method were laid. Subsequently, the geography of laboratories using the polarographic method expanded considerably. This was mainly due to the students of J. Heyrovský, among whom was Yevgeniya Nikolayevna Varasova. The scientific activity of Varasova played a critical role in establishing polarography in the Soviet Union, a country that became one of the leading contributors to electrochemical analysis in the twentieth century. The many schools of polarography in the Soviet Union are a vivid testimony to this. Polarography and general electroanalytical chemistry, together with fundamental electrochemistry developed by A.N. Frumkin, contributed to the worldwide reputation of the Soviet Union as a centre of science in the twentieth century. This happened, despite the international isolation and internal political atrocities of the Soviet system, thanks to the dedicated work of its scientists. This article, based on archival data, reflects the events of Varasova’s tragically short life, her scientific achievements and her actions aimed at introducing polarographic equipment and methods into the work of Soviet scientific and industrial laboratories.</p></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"29 10","pages":"4339 - 4354"},"PeriodicalIF":2.6,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145057680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influence of temperature on the corrosion process, the critical micellar concentration (CMC) of SDS, and its inhibition efficiency were evaluated using conductimetry, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization and inductively coupled plasma-optical emission spectrometry (ICP-OES). Two samples of grey cast iron, GCI-A and GCI-B, were studied. The presence of varying percentages of copper and manganese in the chemical composition of grey cast iron enhances its corrosion resistance. In phosphoric acid solutions, the surface charge of grey cast iron becomes negative in the presence of SDS molecules, as SDS adsorbs onto the metal surface through both chemical and physical interactions, acting as a mixed-type inhibitor by blocking anodic and cathodic reaction sites. Increasing the phosphoric acid concentration decreases the critical micellar concentration (CMC) of SDS, whereas an increase in temperature has the opposite effect. The addition of SDS at a concentration of 10⁻<sup>4</sup> M significantly reduces iron dissolution in both grey cast iron alloys studied. Consequently, SDS decreases both anodic and cathodic current densities, effectively inhibiting the corrosion process of grey cast iron in phosphoric acid solutions, with an inhibition efficiency of approximately 95%. SEM analysis revealed that SDS protects the grey cast iron surface by reducing the size and density of graphite flakes. The inhibitive properties of SDS highlight its potential importance in the conservation and restoration of grey cast iron objects.</p></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"29 10","pages":"4305 - 4324"},"PeriodicalIF":2.6,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145057567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These devices have gained increasing attention this century as they have the possibility of valorising otherwise wasted (heat) energy to useful (electrical) energy with no moving parts, no greenhouse gas emissions, and using sustainably sourced elements such as iron (Fe). Liquid thermocells suffer from several issues including electrolyte leakage, lower ‘observed’ temperature gradients than those applied and poor mechanical properties. Towards applications such as body heat harvesting — where thermal energy sources are dynamic — these disadvantages can become significant. Gelled electrolyte thermocells have been developed as these are self-contained systems that achieve higher temperature gradients across the thermocell and have mechanical properties that allow the ability to stretch, bend, and twist. This makes gelled thermocells compatible with many of the proposed applications of these devices. However, compared to liquid electrolyte thermocells, gelled electrolyte thermocells typically achieve significantly lower performance, mainly due to frustrated ion transport in the denser matrix, reducing the generation of current, which also leads to reductions in power output over time. This review provides an overview of the current state of gelled electrolyte thermocells and compares them to their liquid counterparts.</p></div>","PeriodicalId":665,"journal":{"name":"Journal of Solid State Electrochemistry","volume":"29 2024","pages":"2055 - 2074"},"PeriodicalIF":2.6,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10008-025-06294-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mixed surfactants are more effective than single surfactants at reducing the surface tension of a solution and have a more significant impact on synthesis and modification. Mixed surfactants can also regulate interlayer spacing, morphology, and loading to acquire high capacitance performance. In this study, NiCo-LDH binder-free electrodes are fabricated on foam nickel using the hydrothermal method, with micelles formed by mixing sodium octyl sulfonate (SOS) and cetyltrimethylammonium bromide (CTAB) serving as soft templates.
