In this study, through reasonable composition design, three elements of Zn, Mn and Ca, which are harmless to human body, were selected for alloying magnesium. The effects of ECAP treatment on the microstructure and corrosion properties of Mg-4Zn-1Mn-0Ca, Mg-4Zn-1Mn-0.2Ca and Mg-4Zn-0Mn-0.2Ca alloys were studied. The corrosion mechanism of Mg-Zn-Mn-Ca alloys with different components in Simulated. Body fluid (SBF) was analyzed by weight loss method and electrochemical test. The grains and the second phase were refined by Equal Angular Channel Pressing (ECAP). It was found that after 8 ECAP deformations, the microstructure of the alloy was refined and more uniform than that of the extruded alloy. The corrosion resistance of the Mg-Zn-Mn-Ca alloy after ECAP deformation in simulated body fluids was studied by electrochemical testing techniques, immersion experiments and observation of the microstructure and morphology of corrosion products. The relationship between microstructure characteristics, the behavior of the magnesium metal matrix and the properties of corrosion products was revealed. The results show that the microstructure of the alloy is refined and the corrosion resistance is improved with the increase in extrusion passes in the SBF solution. The corrosion resistance of magnesium alloy after 8 ECAP deformation is the best, showing small Icorr and large Rt. With the extension of the soaking time, the surface of the alloy will form a passivation film, which will protect the matrix and avoid further corrosion of the alloy. It is found that in SBF, the corrosion of the alloy surface is mainly pitting, which indicates that Ca²⁺, HCO^3- and HPO₄^2- in SBF can reduce the corrosion rate of magnesium alloy.

本研究通过合理的成分设计，选择了对人体无害的 Zn、Mn 和 Ca 三种元素作为镁的合金。研究了 ECAP 处理对 Mg-4Zn-1Mn-0Ca、Mg-4Zn-1Mn-0.2Ca 和 Mg-4Zn-0Mn-0.2Ca 合金微观结构和腐蚀性能的影响。模拟体液（SBF）中不同成分的 Mg-Zn-Mn-Ca 合金的腐蚀机理。通过失重法和电化学测试分析了体液（SBF）中的腐蚀机理。采用等角通道压制法（ECAP）对晶粒和第二相进行了细化。结果发现，经过 8 次 ECAP 变形后，合金的微观结构比挤压合金更加细化和均匀。通过电化学测试技术、浸泡实验和观察腐蚀产物的微观结构和形态，研究了 ECAP 变形后的 Mg-Zn-Mn-Ca 合金在模拟体液中的耐腐蚀性。研究揭示了微观结构特征、金属镁基体行为和腐蚀产物特性之间的关系。结果表明，随着在 SBF 溶液中挤压次数的增加，合金的微观结构得到细化，耐腐蚀性能得到改善。随着浸泡时间的延长，合金表面会形成一层钝化膜，从而保护基体，避免合金进一步腐蚀。研究发现，在 SBF 中，合金表面的腐蚀主要是点蚀，这表明 SBF 中的 Ca2+、HCO3- 和 HPO42- 能降低镁合金的腐蚀速率。

Lithium-sulfur (Li-S) batteries are regarded to be the most probable‌ electrochemical energy storage devices for large-scale applications because of their high energy and green characteristics. Nevertheless, the polysulfides generated during the cycle of Li-S batteries can cause the "shuttle effect", reducing the utilization rate of sulfur (S) and electrochemical performance. In this study, a novel three-dimensional composite fiber (TDCF) interlayer was prepared and placed between the S cathode and the PP separator to adsorb polysulfide and restrain the "shuttle effect". The results show that the capacity retention rate of Li-S battery is still higher 3:50 ratio, 200 ml of anhydrous ethanol was added to moisten, than 70 % after 200 charge-discharge cycles at 1 C.

锂硫（Li-S）电池因其高能量和绿色环保的特点，被认为是最有可能大规模应用的电化学储能装置。然而，锂硫电池在循环过程中产生的多硫化物会造成 "穿梭效应"，降低硫（S）的利用率和电化学性能。本研究制备了一种新型三维复合纤维（TDCF）夹层，并将其置于 S 阴极和聚丙烯隔膜之间，以吸附多硫化物并抑制 "穿梭效应"。结果表明，在 1 C 下充放电循环 200 次后，锂-S 电池的容量保持率仍比 3:50 的比例（加入 200 毫升无水乙醇湿润）高出 70%。

In the present research, a novel photoelectrochemical (PEC) sensor was built to detect cefazolin sodium. A copper tetraamino phthalocyanine (CuTAPc) covalently linked graphene oxide compound (CuTAPc-GO) was fabricated successfully by covalent bonding of CuTAPc with graphene oxide (GO). The novel PEC sensing platform was prepared using CuTAPc-GO as a photoelectric material. The prepared PEC sensor showed a higher PEC efficiency under red light. In the perfect conditions, the PEC sensor exhibited a linear correlation in detecting cefazolin sodium concentrations between 0.25 and 12.5 μM, featuring a detection limit at 0.15 μM. Furthermore, the manufacturing sensor was employed to detect cefazolin sodium in a real-world sample, demonstrating commendable sensitivity and stability. Thus, our study provides a new method for cefazolin sodium detection.

Perform headspace SPE in 10 ml solution, and optimized parameters as follows: NaCl dosage 1.5 g, solution pH 5.5, extraction temperature 50℃ and extraction time 35 min. During the CE process, the effects of separation conditions such as pH value, ionic strength, additional additives, and separation voltage on the separation efficiency of nine organophosphorus were studied. The optimized CE conditions are as follows: the separation solution is a phosphate buffer solution with pH 7.0, containing 45 mmol/L NaCl and 25 mmol/L pyrrolidone, and the separation voltage is 17 kV. All nine organophosphorus showed good linear relationships. Their detection limits were 0.5–0.7 μg/kg. Their quantitation limits were 1.0–1.2 μg/kg. The recoveries were 85.2 % - 113.3 %.

The safe and stable operation of lithium-ion batteries in electric vehicles is crucial. Aiming at the problems of a large workload of online estimation and prediction and inability to weigh the whole life cycle of the battery in the joint estimation of SOH (State of Health) and RUL (Remaining Useful Life) for traditional lithium-ion batteries, this paper proposes an optimization scheme for the joint analysis of SOH-RUL. First, the article extracts suitable health features. It utilizes an integrated Extreme Learning Machine (ELM) to estimate the SOH of the battery and inputs the estimates into a Regression Vector Machine (RVM) model for RUL prediction. To better cope with the phenomenon of "sudden capacity change" in batteries, this paper divides the entire life cycle into the early and late stages. A lower estimation frequency and model integration are employed in the early stage.In contrast, the estimation frequency and model integration are increased later to balance speed and safety in total life cycle estimation. Finally, validation was performed on the NASA and CALCE datasets, comparing the effect of constant estimated frequency and model integration with that of varying estimated frequency and model integration at different aging stages. The RMSE of SOH estimation error for both datasets is within 2 % during the early and late stages, and the SOH estimation error for the entire lifecycle is within 2 %. The absolute RUL prediction error for the NASA dataset is below five times; for the CALCE dataset, it is below 20 times in most cases.

电动汽车中锂离子电池的安全稳定运行至关重要。针对传统锂离子电池的 SOH（健康状态）和 RUL（剩余使用寿命）联合估算中存在的在线估算和预测工作量大、无法权衡电池整个生命周期等问题，本文提出了一种 SOH-RUL 联合分析的优化方案。首先，本文提取了合适的健康特征。它利用集成的极限学习机（ELM）来估算电池的 SOH，并将估算结果输入回归向量机（RVM）模型以预测 RUL。为了更好地应对电池的 "容量突变 "现象，本文将整个生命周期分为早期和晚期两个阶段。在早期阶段，采用较低的估算频率和模型集成度；而在后期阶段，则提高估算频率和模型集成度，以平衡整个生命周期估算的速度和安全性。最后，在 NASA 和 CALCE 数据集上进行了验证，比较了在不同老化阶段恒定估算频率和模型积分与改变估算频率和模型积分的效果。在早期和晚期阶段，两个数据集的 SOH 估计误差均方根误差均在 2% 以内，整个生命周期的 SOH 估计误差均在 2% 以内。NASA 数据集的绝对 RUL 预测误差低于 5 倍；CALCE 数据集的绝对 RUL 预测误差在大多数情况下低于 20 倍。

Designing efficient, cheap catalysts for oxygen production is very important for water electrolysis and green hydrogen production. Here, synthesis and electrocatalytic performance of graphene oxide (GO)/nickel-aluminum layered double hydroxide (NiAl-LDH) composites were investigated for water-splitting applications. The composition, microstructure, and morphology of the nanocomposites were confirmed by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), and field emission scanning electron microscopy (FE-SEM), and their water oxidation performance was examined in 0.1 M potassium hydroxide solution in the presence and absence of magnetic field. The results show that optimized GO/NiAl-LDH nanocomposite (GO-1 %/NiAl-LDH) exhibits the lowest overpotential compared with other prepared nanocomposites. This performance demonstrates comparable electroactivity to well-developed electrocatalysts like the perovskite-based electrodes, it also shows an improved electrocatalytic activity compared to NiAl-LDHs due to the presence of graphene oxide in the composite. We interpreted this significant performance to improve electron transform and high active site at the synthesized GO/NiAl-LDH composites. The best electrocatalytic activity with an overpotential of 443 and 473 mV at the current density 10 mA.cm⁻² were evidenced for GO-1 %/NiAl-LDH nanocomposite in the presence and absence of external magnetic field, respectively. Furthermore, the tafel slope were reported about 54 and 162 mV.dec⁻¹ in the presence and absence of magnetic field, respectively. This improved water oxidation can be attributed to the magneto-hydrodynamic effect and the increased number of metal sites on LDHs under the magnetic field.

Conventional micro-turning of metal materials with low rigidity and hardness is highly challenging. Electrochemical Discharge Machining (ECDM) offers an alternative approach for fabricating micro shafts. However, micro-turning by ECDM often leads to severe flaring at the shaft shoulder due to stray corrosion. To mitigate this issue, we propose two novel methods for insulating the sidewalls of the cathode tool: applying insulating tape to the sides of a rectangular cathode tool or attaching aluminum foil along the bottom edge of a rectangular acrylic plate. We evaluated the machining performance of these cathode tools on the 3 mm diameter copper rods. Experimental results demonstrate that using an acrylic plate with attached aluminum foil as the cathode tool significantly enhances machining accuracy in the transition area of the shaft shoulder. Additionally, the simplicity and reliability of this method highlight its advantages.

对刚度和硬度较低的金属材料进行传统的微车削加工极具挑战性。电化学放电加工（ECDM）为制造微型轴提供了另一种方法。然而，由于杂散腐蚀，电化学放电加工（ECDM）的微车削往往会导致轴肩处出现严重的扩口。为了缓解这一问题，我们提出了两种新颖的阴极工具侧壁绝缘方法：在矩形阴极工具的两侧贴上绝缘胶带，或在矩形丙烯酸板的底边贴上铝箔。我们对这些阴极工具在直径为 3 毫米的铜棒上的加工性能进行了评估。实验结果表明，使用附有铝箔的丙烯酸板作为阴极工具，可显著提高轴肩过渡区域的加工精度。此外，这种方法的简便性和可靠性也凸显了它的优势。

The study presents a comprehensive design and evaluation of a kilowatt-class proton exchange membrane fuel cell (PEMFC) stack, wherein stainless steel fiber felts are innovatively utilized as flow fields. The impacts of critical operating parameters, namely operating temperature, pressure, and reactant gas relative humidity, on the performance of the 22-cell stack with an active area of 83 cm² were thoroughly investigated. An analysis of the voltage consistency among individual cells was conducted across varying operating conditions and output currents. The total power output of the PEMFC stack reaches 1183 W under the fundamental operating conditions, where each cell achieves an average voltage of 0.6 V. As the operating temperature and pressure are incremented, the stack’s output power exhibits a noticeable increase. The optimal range for the reactant gas relative humidity is found to be 60–80 %. As the output current increases, the voltages of individual cells gradually decrease and the voltage consistencies tend to deteriorate. The optimal operating conditions for achieving the best voltage consistency vary with current density.

The need to determine esomeprazole in pharmaceutical formulations and biological fluids with high accuracy arises to ensure proper dosage and follow-up on patient response. In the present investigation, Glassy Carbon Electrode (GCE) was modified by potentiodynamic electropolymerization of Diaquabis(1,10-phenanthroline copper (II) Iodide ([Cu(H₂O)₂P₂]I₂) on its surface with a fixed number of cycles. Cyclic voltammetry (CV) was used to characterize the voltammetric redox behavior of esomeprazole (ESO) on poly([Cu(H₂O)₂P₂]I₂)/GCE and the best reversible oxidative current response has been obtained. On the proposed electrode, the electrochemical activity of the ESO was enhanced at a peak intensity that was around 2.6 times higher than the bare one. The calibration curve for ESO at poly([Cu(H₂O)₂P₂]I₂)/GCE has a linear region for a concentration range of 0.01–200 µM with the detection limit and limit of quantifications of 28.90 and 95.53, respectively and the associated standard deviation was 0.59 %. he current sensor has also been effectively used to detect esomeprazole in clinical fluid samples and pharmaceutical samples in a sensitive and selective approach. The outstanding recovery percentage in the range of 95.97–105.26 % in the presence of 50–300 % potential interferents indicated an excellent accuracy and selectivity of the proposed sensor towards ESO in the presence of potential interferants. The proposed method is simple, quick, stable, and effective for real sensor applications for esomeprazole sensing in different samples.

因此需要高精度地测定药物制剂和生物液体中的埃索美拉唑，以确保剂量适当并跟踪患者的反应。在本研究中，通过在玻璃碳电极（GCE）表面以固定的循环次数聚合双(1,10-菲罗啉)碘化亚铜（II）（[Cu(H2O)2P2]I2），对玻璃碳电极（GCE）进行了改性。使用循环伏安法（CV）表征了埃索美拉唑（ESO）在聚（[Cu(H2O)2P2]I2）/GCE 上的伏安氧化还原行为，并获得了最佳的可逆氧化电流响应。在所提出的电极上，ESO 的电化学活性得到了增强，其峰值强度是裸电极的约 2.6 倍。在聚([Cu(H2O)2P2]I2)/GCE 上，ESO 的校准曲线在 0.01-200 µM 的浓度范围内呈线性，检出限和定量限分别为 28.90 和 95.53，相关标准偏差为 0.59%。在存在 50%-300% 潜在干扰物的情况下，该传感器的回收率在 95.97-105.26% 之间，这表明在存在潜在干扰物的情况下，该传感器对 ESO 具有极佳的准确性和选择性。所提出的方法简单、快速、稳定、有效，可用于不同样品中埃索美拉唑传感器的实际应用。

Titanium and its alloys are widely used in various fields owing to their exceptional wear resistance, heat resistance and biocompatibility. However, they still exhibit shortcomings, such as insufficient corrosion resistance, when used in specific working environments. micro-arc oxidation (MAO) has gained considerable attention in recent years for the preparation of ceramic coatings with good bonding force, wear resistance, corrosion resistance, and biological activity on aluminum, magnesium, titanium, and their alloys. Because of the porous structure of MAO coatings, researchers often enhance the corrosion resistance of MAO coatings on titanium and its alloys by incorporating different types of additives or using pre- and post-treatment processes. This paper reviews the mechanism of MAO technology and the effects of various types of additives and pre- and post-treatment processes on the corrosion resistance of MAO coatings on titanium and its alloys based on recent literature and predicts future development trends.
