Electronic sensors are essential in applications like biosensors and fuel cells, providing rapid solutions for substance detection. Integrating electrochemical sensors into textiles offers advantages such as flexibility, comfort, and potential for wearable applications. This study explores the suitability of three textile substrates—100 % polyester knit mesh (S1), 100 % recycled polyester knit mesh (S2), and 50 % recycled polyester/50 % hemp fabric (S3)—for constructing screen-printed electrodes (SPEs). The goal is to develop a textile-based electrochemical sensor with a 3-electrode system (reference, auxiliary, and working electrode) using semi-automated screen printing. The electrochemical performance of two carbon inks, Elantas 9553 and DuPont BQ242, was evaluated to select the best working electrode (WE) ink. DuPont BQ242 was found most suitable for WE production, exhibiting quasi-reversible behavior and temperature stability. The electrochemical behavior of the textile-SPEs printed with DuPont BQ242 revealed that substrate S3 had superior properties, with higher peak currents (peak current ratio of 1.2) and smaller peak potential separation (602 n/V). Carbon Elantas 9553 was more sensitive to temperature changes (1 % variation) than the more stable DuPont BQ242 (0.03 % variation). The stability of the inks on substrates was examined using the 4-point probe method, highlighting excellent electrical stability under UV, high temperatures, cosmetics, and artificial sweat. The final textile-based SPE outperformed commercial SPEs, showing superior redox properties, with a peak potential separation (ΔEp) 56 % smaller and a relative standard deviation (RSD) of 1.58 % over 20 measurements. These textile-based SPEs present a valuable alternative to conventional rigid sensors, which are typically single-use and less durable.

电子传感器在生物传感器和燃料电池等应用中至关重要，可为物质检测提供快速解决方案。将电化学传感器集成到纺织品中具有灵活性、舒适性和可穿戴应用潜力等优势。本研究探讨了三种纺织品基材--100% 聚酯针织网（S1）、100% 再生聚酯针织网（S2）和 50% 再生聚酯/50% 麻织物（S3）--在构建丝网印刷电极（SPE）方面的适用性。我们的目标是利用半自动丝网印刷技术开发一种基于纺织品的电化学传感器，该传感器具有 3 个电极系统（参比电极、辅助电极和工作电极）。对 Elantas 9553 和杜邦 BQ242 两种碳油墨的电化学性能进行了评估，以选出最佳工作电极 (WE) 油墨。结果发现，杜邦 BQ242 最适合用于生产工作电极（WE），它具有准可逆性和温度稳定性。使用杜邦 BQ242 印刷的纺织品-SPE 的电化学行为表明，基底 S3 具有更优越的性能，峰值电流更高（峰值电流比为 1.2），峰值电位分离更小（602 n/V）。碳 Elantas 9553 对温度变化的敏感度（变化 1%）高于更稳定的杜邦 BQ242（变化 0.03%）。使用 4 点探针法检测了油墨在基底上的稳定性，结果表明，在紫外线、高温、化妆品和人工汗液条件下，油墨具有出色的电气稳定性。最终的纺织品基固相萃取剂优于商用固相萃取剂，显示出卓越的氧化还原特性，在 20 次测量中，峰值电位分离 (ΔEp) 小 56%，相对标准偏差 (RSD) 为 1.58%。这些基于纺织品的固相萃取剂是传统刚性传感器的重要替代品，传统刚性传感器通常是一次性使用，耐用性较差。

Electrochemical Impedance Spectroscopy (EIS) is a technique widely used in the electrochemistry field that allows assessing the kinetic parameters of electrochemical systems. In general, EIS spectra are analyzed using 2 methodologies: the physical–mathematical methodology and the Equivalent Electrical Circuit (EEC) methodology. The physical–mathematical methodology consists in developing and solving the set of differential equations that govern the system. In contrast, the EEC methodology describes EIS data in terms of EEC models, decreasing the math complexity and democratizing the use of the EIS technique. In the EEC methodology, the most critical task is selecting a physically sound EEC model. To help with the EEC model selection, Prof. Digby D. Macdonald proposed creating the Electrochemistry’s Genome Project, which would consist of a large database and an Artificial Intelligence (AI) able to suggest plausible EEC models given an EIS spectrum. Until now, several works have explored the idea of using Machine Learning (ML) for recommending an EEC for a given EIS spectrum. Indeed, several authors have benchmarked different ML algorithms for this task. However, these benchmarks generally report point estimates of the accuracy achieved by each algorithm, but do not assess its uncertainty.

In this work, we benchmarked different ML EEC recommendation algorithms. To achieve this, we refined a preexistent database, obtaining a new database. Then, the new database was used to train different ML algorithms, optimize their hyperparameters, and assess their accuracy. Finally, the performance of the different optimized algorithms were compared. Whereas most of the other benchmarks available in literature work with point estimates of the accuracies, in this work, the accuracy distributions have been estimated. This methodology allows to compare the performance of the different algorithms in a much more reliable and robust way.

电化学阻抗光谱法（EIS）是一种广泛应用于电化学领域的技术，可以评估电化学系统的动力学参数。一般来说，EIS 光谱分析采用两种方法：物理数学方法和等效电路 (EEC) 方法。物理数学方法包括建立和求解支配系统的微分方程集。相比之下，等效电路方法是用等效电路模型来描述 EIS 数据，从而降低了数学复杂性，并使 EIS 技术的使用平民化。在 EEC 方法中，最关键的任务是选择一个物理上合理的 EEC 模型。为了帮助选择 EEC 模型，Digby D. Macdonald 教授提议创建 "电化学基因组计划"，该计划将由一个大型数据库和一个人工智能（AI）组成，人工智能（AI）能够在给定 EIS 频谱的情况下提出可信的 EEC 模型。迄今为止，已有几项研究探讨了使用机器学习（ML）为给定的 EIS 频谱推荐 EEC 的想法。事实上，有几位作者已经针对这项任务对不同的 ML 算法进行了基准测试。然而，这些基准通常报告的是每种算法所达到的精确度的点估计，但并不评估其不确定性。为此，我们完善了一个已有的数据库，得到了一个新的数据库。然后，使用新数据库训练不同的 ML 算法，优化其超参数，并评估其准确性。最后，比较不同优化算法的性能。文献中的大多数其他基准都是对准确度进行点估算，而在这项工作中，则是对准确度分布进行估算。通过这种方法，可以更可靠、更稳健地比较不同算法的性能。

In this paper, the problem of synthesizing hollow structures as a photoactive material for water electrolysis is addressed using the example of ZnO microtubes. In the study, a novel method of electrochemical template-assisted synthesis was applied to produce microtubes. The influence of zinc electrodeposition conditions (mode and electrolyte) and annealing on the photoelectrocatalytic (PEC) properties of the electrode material was evaluated. Samples prepared from citrate and zincate electrolytes were analyzed using scanning electron microscopy, energy dispersive X-ray mapping, X-ray diffraction, diffuse reflectance spectroscopy, photogalvanic response, voltammetry, and electrochemical impedance spectroscopy. The purpose of this paper was to demonstrate the advantages of using a citrate electrolyte over a classical zincate electrolyte for the electrochemical template method. It has been found that using citrate electrolyte allows for the production of ZnO microtubes that improve the PEC performance by 1.5–2 times. The effect of the synthesis conditions of the electrode material on the charge transfer resistance and diffusion limitations in the water splitting reaction is analyzed.

The speedy utilization and exploitation of fossil fuels lead to establishment of an ecosystem marked by pollution and the depletion of energy resources. Nevertheless, expediting the progress of alternative approaches to generate energy and fabricate energy storage devices is crucial. In such cases, supercapacitors (SC) emerged as the most auspicious energy storage device in terms of performance. Supercapacitors can have their electrochemical efficiency enhanced by employing several electrode materials, including transition metal oxides, chalcogenides, perovskites, and spinel. As an electrode for improved SC applications, a new BaS/CuS composite was created in this work using a hydrothermal method. The physical characterizations confirmed the proof of successful fabrication. BET results show that the prepared composite of the BaS/CuS has enhanced surface area (87.4 m² g⁻¹). BaS/CuS composite electrode was tested in alkaline media via three electrode configurations, and it demonstrated the high C_s (908.7F/g at 1 A/g), high energy density, and power density of 68.6 Wh kg⁻¹ and 368.6 W kg⁻¹ respectively, and good cyclic stability. According to the previously described findings, the synthesized electrode is promising for supercapacitor use.

化石燃料的快速利用和开采导致了以污染和能源枯竭为特征的生态系统的建立。尽管如此，加快替代能源生产和能源存储设备制造方法的发展至关重要。在这种情况下，超级电容器（SC）成为性能最佳的储能设备。超级电容器可以通过采用多种电极材料（包括过渡金属氧化物、瑀、过氧化物和尖晶石）来提高其电化学效率。作为改进超级电容器应用的电极，本研究采用水热法制备了一种新型 BaS/CuS 复合材料。物理表征证实了制备的成功。BET 结果表明，制备的 BaS/CuS 复合材料具有更高的表面积（87.4 m2 g-1）。在碱性介质中通过三种电极配置对 BaS/CuS 复合电极进行了测试，结果表明该电极具有高铯（908.7F/g，1 A/g 时）、高能量密度和功率密度（分别为 68.6 Wh kg-1 和 368.6 W kg-1）以及良好的循环稳定性。根据之前的研究结果，合成的电极有望用于超级电容器。

The research delves into a comprehensive process for synthesizing and characterizing NdFeO₃, reduced graphene oxide (rGO), and their composite. In present work, the NdFeO₃/rGO composite is synthesized using ultrasonic methods. Subsequently, techniques such as FT-IR, XRD, SEM, EDX, and XPS univocally affirmed the synthesis of NdFeO₃/rGO. The pristine materials NdFeO₃, rGO, and NdFeO₃/rGO were investigated for oxygen evolution reaction (OER) and hydrogen evolution reaction. The findings reveal that the NdFeO₃/rGO composite exhibits superior OER and HER compared to individual components in the presence of 1 M KOH solution. The NdFeO₃/rGO at current densities of 100, 500 and 1000 mAcm⁻² displays lower overpotentials 220, 255 and 345 mV for OER and enhanced stability over extended testing periods for 80 h. Similarly, composite at current densities of 100, 500, and 1000 mAcm⁻² to acquire overpotentials of 206, 301, and 466 mV, respectively. The exalted electrocatalytic performance of NdFeO_3/rGO is related to the production of synergism between NdFeO₃ and rGO, promoting faster charge transfer kinetics and catalytic activity. Overall, the study underscores the potential of NdFeO₃/rGO as promising and inexpensive electrocatalysts for OER and HER, offering significant promise for applications in sustainable energy conversion.

该研究深入探讨了合成和表征氧化钕、还原氧化石墨烯（rGO）及其复合材料的综合过程。在本研究中，采用超声波方法合成了 NdFeO3/rGO 复合材料。随后，傅立叶变换红外光谱（FT-IR）、X射线衍射（XRD）、扫描电子显微镜（SEM）、电子发射光谱（EDX）和 XPS 等技术一致证实了 NdFeO3/rGO 的合成。对原始材料 NdFeO3、rGO 和 NdFeO3/rGO 进行了氧进化反应（OER）和氢进化反应的研究。研究结果表明，在 1 M KOH 溶液中，NdFeO3/rGO 复合材料的氧进化反应和氢进化反应均优于单个成分。在电流密度为 100、500 和 1000 mAcm-2 时，NdFeO3/rGO 在 OER 反应中的过电位分别为 220、255 和 345 mV，且在 80 小时的长时间测试中稳定性更强。NdFeO3/rGO 杰出的电催化性能与 NdFeO3 和 rGO 之间产生的协同作用有关，这种协同作用促进了电荷转移动力学和催化活性。总之，该研究强调了 NdFeO3/rGO 作为前景广阔且成本低廉的 OER 和 HER 电催化剂的潜力，为其在可持续能源转换领域的应用提供了巨大前景。

A simple and efficient microwave-assisted synthesis route was adopted for carbon aerogel (CA)-supported Cu and Fe catalysts for OER in alkaline media. Catalysts were characterized physically by ICP-MS, XRD, TEM, XPS, SEM, and EDX and electrochemically by CV, chronoamperometry, and EIS. The catalyst having the composition of Cu₃₀Fe₇₀/CA showed excellent activity towards OER with low overpotential (345 mV) and Tafel slope (92.5 mV dec⁻¹). Diffusion coefficient (D° = 2.1 × 10⁻⁸ cm² s⁻¹), mass transport coefficient (m_T = 2.8 × 10⁻⁴ cm s⁻¹), heterogeneous rate constant (k° = 5.7 × 10⁻⁴ cm s⁻¹), and electrochemically active surface area (0.0167 cm²) were obtained for Cu₃₀Fe₇₀/CA modified glassy carbon electrode. CV response in the non-faradic region showed that C_dl and electrochemical surface area (ECSA) of Cu₃₀Fe₇₀/CA increased ∼ 34 times compared to Fe/CA. This work suggests that adding up an optimum amount of Cu to the Fe/CA nanocomposite offers a cost-effective and efficient electrocatalyst for OER.

This study explores the synthesis of ultrathin flower architecture of spinel-structured Co₃O₄ electrodes, on nickel foam using a double hydrothermal method, followed by annealing at 250 °C for 4 h. We systematically investigate the effects of varying reaction times and additional Co²⁺ treatment during the second hydrothermal process on the morphology and electrochemical properties of Co₃O₄. Field emission scanning electron microscopy (FE-SEM) images confirm the formation of self-supported hierarchical flowers, characterized by sharp, spike-like nanowires (16–33 nm in diameter) arranged radially. The self-supported optimized hierarchical Co₃O₄ thin film, characterized by its unique architecture and substantial mass loading of 4.6 mg cm⁻², achieved an impressive specific capacitance of 749.48F g⁻¹ at a scan rate of 10 mV s⁻¹ (specific capacity of 182.16 mAh g⁻¹) in 2 M KOH electrolyte and retained 64 % of its initial capacitance after 5000 cycles. Furthermore, a symmetric device demonstrated the ability to illuminate a red LED for approximately 120 s when two devices were connected in series.

In the realm of energy storage, the evolution of lithium-oxygen (Li-O₂) batteries has garnered substantial attention, owing to their potential to revolutionize electric vehicles. For a long time, ideas for sustainable development have positioned platinum group metals (PGMs) as potentially revolutionary, especially in the automotive industry. Intended to enhance Li-O₂ battery performance, PGMs are appealing due to their catalytic activities and this might be a big step forward for the electrification automotive industry and possibly pave the way for longer-lasting batteries used for reasons other than transportation. Therefore, this review explores progressions in PGMs-based electrocatalysts used as electrode materials for Li-O₂ batteries, starting with an overview of the Li-O₂ battery principle and its challenges. It then examines in detail the utilization of PGMs-based electrocatalysts as electrode materials for improving Li-O₂ battery performance. Finally, it addresses the remaining hurdles preventing the full integration of PGMs into battery technologies, offering insights into the current status and future possibilities for PGMs in Li-O₂ battery technology.
