The work presents a new procedure of determination of an antifungal agent tolnaftate (TLN). A quick and simple analysis is proposed, based on the reaction of electrochemical oxidation of the studied analyte on a first-time used bare boron-doped diamond electrode. Before the measurement, the BDD electrode was subject to procedure, which, however, involved an innovative approach of multiple cycling in electrolyte with 0.1 mol/L solution of NaClO₄, in the potential range from −2.9 V to +0.3 V. Sensitive and accurate determination of TLN was possible on an unmodified BDD electrode with the use of square wave voltammetry (SWV), never used with this analyte before. The environment of the studied reaction was optimized in the work, and the B-R buffer with pH = 2.09 proved to be the best electrolyte. An irreversible oxidation peak was obtained in the solution at the potential of 1.3 V (vs. SCE). The analysis of the impact of scan rate on the height of TLN oxidation peak led to the conclusion that the recorded currents have a diffusion character. In the optimum conditions of SWV operation parameters, a linear range of concentrations was obtained from 4.9·10⁻⁶ to 8.6·10⁻⁵ mol/L, with LOD of 4.3·10⁻⁷ mol/L, LOQ of 1.3·10⁻⁶ mol/L, and the coefficient of determination close to one (0.9977). TLN was successfully determined in a pharmaceutical preparation and in artificial sweat. The obtained recovery of the proposed procedure was in the range from 94.95% to 100.92%.

本文提出了一种测定抗真菌药物托萘乙酸酯（TLN）含量的新方法。本文提出了一种快速、简便的分析方法，该方法基于所研究的分析物在首次使用的裸掺杂硼金刚石电极上的电化学氧化反应。在测量之前，BDD电极要经过一个程序，该程序涉及到一个创新的方法，即在−2.9 V至+0.3 V的电位范围内，在含有0.1 mol/L NaClO4溶液的电解质中多次循环。使用方波伏安法（SWV）可以在未经修饰的BDD电极上灵敏准确地测定TLN，而这种方法以前从未用于该分析物。工作中对反应环境进行了优化，pH = 2.09的B-R缓冲液为最佳电解液。溶液在1.3 V （vs. SCE）电位下出现不可逆氧化峰。通过分析扫描速率对TLN氧化峰高度的影响，得出记录电流具有扩散特征的结论。在最佳SWV操作条件下，样品浓度在4.9·10−6 ~ 8.6·10−5 mol/L范围内呈线性关系，LOD为4.3·10−7 mol/L， LOQ为1.3·10−6 mol/L，测定系数接近1（0.9977）。成功地测定了药物制剂和人工汗液中的TLN。该方法的回收率为94.95% ~ 100.92%。

Fabrication of nanostructures in single-crystal diamond is of crucial importance for various applications in sensing, optics, electronics, microelectromechanical systems (MEMS), etc. However, it is not trivial to achieve some design requirements of these nanostructures in fabrication processes, especially when certain device concepts require high aspect-ratio (HAR), exact tapering angle, or sharp edge/tip radius. We devise and demonstrate a top-down process flow leveraging self-aligned patterning technique that allows us to fabricate stepped conical nanopillars with height ranging from 3 to 5.5 μm, and tip radius from 5 to 200 nm. This stepped structure can be designed and manufactured for enhanced stiffness or for extended aspect ratio depending on device requirements. The fabrication process is applicable for standard wafer-level MEMS foundries, and could be readily used for the fabrication of scanning probes, electron emission electrodes, nanoindenter tips, etc., with high uniformity and repeatability in a scaled up fashion.

单晶金刚石纳米结构的制备对于传感、光学、电子、微机电系统（MEMS）等领域的应用具有重要意义。然而，在制造过程中实现这些纳米结构的一些设计要求并非易事，特别是当某些器件概念需要高宽高比（HAR），精确的锥度角或锋利的边缘/尖端半径时。我们设计并演示了一种自上而下的工艺流程，利用自对准图像化技术，使我们能够制造高度从3到5.5 μm，尖端半径从5到200 nm的阶梯锥形纳米柱。这种阶梯式结构可以根据设备要求设计和制造增强刚度或扩展宽高比。该工艺适用于标准晶圆级MEMS代工厂，可用于扫描探头、电子发射电极、纳米压头尖端等的制造，具有高均匀性和可重复性。

To overcome limitations in conventional terahertz absorbers—such as limited channels, single-mode operation, and challenges in balancing high selectivity with broadband response, a dynamically tunable terahertz absorber based on a graphene-VO₂ hybrid metamaterial is proposed and numerically investigated. By combining the electrically tunable Fermi level of graphene with the insulator-metal phase transition of VO₂, reversible switching between eight narrowband frequency-selective absorption modes and an ultra-broadband absorption mode is achieved within a single structure. When VO₂ is in the metallic state and the graphene Fermi level is 0 eV, broadband absorption exceeding 90% is realized over 2.4–7.14 THz. In contrast, when VO₂ is in the insulating state and the graphene Fermi level is increased to 1 eV, eight well-defined narrowband resonances with high frequency selectivity are obtained. Impedance matching and electric field analyses reveal that the absorption performance arises from the excitation and coupling of multiple localized surface plasmon resonance modes. The proposed absorber offers a compact and effective strategy for multifunctional and reconfigurable terahertz devices.

为了克服传统太赫兹吸收器的局限性，如有限的通道、单模操作以及平衡高选择性和宽带响应的挑战，提出了一种基于石墨烯- vo 2混合超材料的动态可调谐太赫兹吸收器，并进行了数值研究。通过将石墨烯的电可调谐费米能级与VO₂的绝缘体-金属相变相结合，在单个结构内实现了八个窄带频率选择吸收模式和一个超宽带吸收模式之间的可逆切换。当VO₂处于金属态，石墨烯费米能级为0 eV时，在2.4 ~ 7.14 THz范围内实现了超过90%的宽带吸收。相比之下，当VO 2处于绝缘状态时，石墨烯的费米能级增加到1 eV，得到了8个具有高频率选择性的窄带共振。阻抗匹配和电场分析表明，吸收性能是由多个局域表面等离子体共振模式的激发和耦合产生的。所提出的吸收器为多功能和可重构太赫兹器件提供了一种紧凑有效的策略。

Polymer nanocomposites often contain a partial interphase that influences their performance; however, this aspect was rarely studied in the literature. In this work, the conductivity of a partial interphase in the composites of carbon nanofiber (CNF) named as PCNFs is analyzed based on CNF properties and the magnitude of conduction moving via the partial interphase. Additionally, percolation inception, network ratio, and tunneling zone resistance are examined, assuming the formation of CNF/partial interphase networks. A conductivity model for PCNFs is then developed using these factors. The parameters in the equations for interphase conductivity (ψ), net proportion, and composite conductivity are evaluated and explained. Similarly, experimental data are provided to validate the developed equations for percolation inception and PCNF conductivity. Increased conduction transfer through the partial interphase, reduced CNF waviness, and the slimmer and longer nanofibers enhance interphase conductivity and network formation, leading to improved overall conductivity. An interphase size (t) of 30 nm and ψ = 1000 S/m increase nanocomposite conductivity to 0.23 S/m, whereas t < 7 nm results in an insulated PCNF. The densest interphase with the highest conductivity yields the greatest conductivity, whereas an extremely thin interphase cannot provide the charge transfer.

聚合物纳米复合材料通常含有影响其性能的部分界面相；然而，这方面的研究在文献中很少。在这项工作中，基于碳纳米纤维（CNF）的性质和通过部分间相移动的传导幅度，分析了pcnf复合材料（CNF）部分间相的电导率。此外，假设CNF/部分相间网络的形成，研究了渗透开始、网络比率和隧道区阻力。然后利用这些因素开发了PCNFs的电导率模型。对相间电导率（ψ）、净比例和复合电导率方程中的参数进行了评价和解释。同样，提供了实验数据来验证所开发的渗流起始和PCNF电导率方程。增加了部分间相的传导传递，减少了CNF的波浪形，更细更长的纳米纤维增强了间相电导率和网络形成，从而提高了整体电导率。当界面尺寸为30 nm， ψ = 1000 S/m时，纳米复合材料的电导率提高到0.23 S/m，而当界面尺寸为7 nm时，则产生绝缘的PCNF。最致密的间相具有最高的电导率，产生最大的电导率，而极薄的间相不能提供电荷转移。

In this study, we present an ecofriendly and simple electrochemical method for synthesizing nano zero-valent iron particles (nZVIs) directly on boron-doped diamond (BDD) electrode surfaces. A BDD electrode served as the substrate for electrodeposition using a 5 mM FeCl₃/0.1 M KCl solution and chronoamperometry at an applied potential of −1.3 V versus Ag/AgCl (1 M KCl), as determined by cyclic voltammetry (CV) and supported by Pourbaix diagram analysis. The electrochemical behavior and surface modification were characterized using CV, electrochemical impedance spectroscopy (EIS), and surface analysis and microscopy techniques. The results confirm that BDD electrodes can serve as effective platforms for a controlled deposition of 56 nm nZVIs, offering a promising strategy for the development of advanced materials for environmental remediation, catalysis, and sensing applications.

The absorber proposed in this study builds upon a water-based absorber by introducing a patterned graphene framework and a patterned gold layer, thereby enhancing its relevant performance. Within the frequency range of 0 to 29 THz (THz), using a 90% absorption rate as the threshold, this absorber achieves an absolute bandwidth of 19.5 THz, a relative bandwidth of 113.44%, and an average absorption rate of 97.92%. It exhibits polarization insensitivity and demonstrates strong robustness against oblique incidence. Furthermore, the absorber maintains excellent performance across a temperature range of 0–60 °C and can be tuned through both electrical and thermal methods. This absorber holds significant promise for applications in thermal detectors, sensors, and terahertz imaging.

Nitrogen and Sulfur Co-doped Carbon Dots (NS-CDs) are synthesized from shrimp shell biomass waste, and L-cysteine, as the carbon source and dopant, using a microwave-assisted method. This study explores the use of biomass waste to develop sustainable high-performance electrode materials for supercapacitors. The synthesized NS-CDs has exhibited the agglomeration of the particle in the diameter ranging from 80 to 100 nm. X-ray diffraction (XRD) analysis has confirmed the characteristic diffraction peaks corresponding to the graphitic carbon planes (002) and (001), while spectroscopic methods further validate the successful incorporation of nitrogen and sulfur dopants by detecting functional groups such as N=C=S. Electrochemical evaluation shows that the sample with a 1:1 ratio of shrimp shell to L-cysteine provides optimal performance, achieving a specific capacitance of 490.22 F/g, the lowest internal resistance of 3.92 Ω, and the highest electrical conductivity of 452.49 S/cm. Furthermore, this optimal sample reaches an energy density of 109.15 Wh/kg and a power density of nearly 598 W/kg. These results demonstrate that shrimp shell-derived NS-CDs could be a promising candidate for sustainable electrode materials in supercapacitor applications.

This study systematically evaluated the tribological behaviors of polycrystalline diamond compact (PDC) when paired with various materials in high temperature drilling fluid. The results demonstrated that PDC/Si₃N₄ exhibited excellent overall performance under high temperature, with both the coefficient of friction and wear rate being significantly lower than those at room temperature. This phenomenon was attributed to an effective wear-oxidation lubrication mechanism: high temperature promoted the formation of a composite synergistic film consisting of both oxide layer and carbonaceous material. In contrast, although PDC/steel showed reduced the coefficient of friction under high temperature, this was accompanied by an increased wear rate. The decrease in the coefficient of friction primarily originated from decreased shear strength due to material softening and improved graphitization degree within the transfer layer. However, high temperature also aggravated both oxidation processes and adhesive wear. Coupled with the corrosion induced by Cl⁻ in the drilling fluid, multiple failure mechanisms interacted synergistically, leading to accelerated wear.

本研究系统评估了聚晶金刚石压片（PDC）与不同材料在高温钻井液中的摩擦学行为。结果表明，PDC/Si3N4在高温下表现出优异的综合性能，摩擦系数和磨损率均显著低于室温。这一现象归因于一种有效的磨损-氧化润滑机制：高温促使氧化层和碳质材料形成复合协同膜。相比之下，尽管PDC/钢在高温下的摩擦系数降低，但同时伴随着磨损率的增加。摩擦系数降低的主要原因是材料软化导致的抗剪强度降低和传递层内石墨化程度的提高。然而，高温也加剧了氧化过程和胶粘剂磨损。再加上钻井液中Cl−的腐蚀作用，多种失效机制协同作用，导致磨损加速。

We report a scalable, one-step fabrication of flexible graphene–gold nanocomposite electrodes via direct laser writing on polyimide substrates using an affordable continuous wave diode laser. Simultaneous laser-induced carbonization of polyimide to porous laser-induced graphene and reduction of gold(III) acetate to uniformly distributed gold nanoparticles yields a conductive and electroactive laser-induced graphene/Au composite. Comprehensive characterization by scanning electron microscopy, energy dispersive X-ray spectroscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy confirms the formation of a defect-rich graphene framework decorated with Au nanoparticles, with optimal laser parameters providing a minimum sheet resistance of 87 ± 5 Ω. The developed LIG/Au electrodes exhibit excellent electrochemical performance for the simultaneous detection of dopamine and paracetamol, achieving detection limits of 16 nM and 36 nM, respectively. Dopamine detection spans two linear ranges (0.1–50 μM and 50–300 μM) with sensitivities of 1.09 and 0.09 μA μM⁻¹ cm⁻², while paracetamol shows a single linear range (0.1–200 μM) with a sensitivity of 0.35 μA μM⁻¹ cm⁻². The flexible sensor demonstrates high selectivity against common biosensing interferents, remarkable mechanical robustness under cyclic bending, and long-term stability with more than 90% signal retention over 30 days. The proposed direct laser writing technique represents a rapid, low-cost, and easily scalable approach for high-throughput fabrication of robust, flexible electrodes suitable for multi-analyte electrochemical analysis.

Efficient methane (CH₄) decomposition is of fantastic importance for energy transition and environmental protection. In this paper, we explored the dehydrogenation reactions of CH₄ on the clean twin T-graphene (TTG) and TM-doped TTG (TM@TTG, TM = Fe, Pd, and Pt), using the first-principles methods. It is found that the doping of TM facilitates the activation and dehydrogenation of CH₄. On the TTG surface, both CH₂ and CH dissociation steps probably are rate-limiting step, while the rate-controlling step may be the CH₂ dissociation for the continuous dehydrogenation of CH₄ molecule on the TM@TTG surfaces. Furthermore, the analysis of transition state reveals that, different from other system where consecutive dehydrogenation of CH₄ is expected to be achieved, methyl has the potential to form C₂H₆ rather than undergoing further dissociation in the case of Pt@TTG substrate. The impact of temperature on the CH₄ dehydrogenation on TM@TTG is also explored. The results suggest that the dehydrogenation of CH₄ on TTG surface can be significantly modulated via a moderate doping of transition metals, and provide a new perspective to design the decomposition process of CH₄ molecule.

高效分解甲烷对能源转型和环境保护具有重要意义。在本文中，我们利用第一性原理方法探索了CH4在清洁双t-石墨烯（TTG）和TM掺杂TTG （TM@TTG, TM = Fe, Pd，和Pt）上的脱氢反应。发现TM的掺杂有利于CH4的活化和脱氢。在TTG表面，CH2解离和CH解离都可能是限速步骤，而控制速率的步骤可能是CH2解离，使TM@TTG表面的CH4分子连续脱氢。此外，对过渡态的分析表明，不同于其他体系期望CH4连续脱氢，在Pt@TTG底物的情况下，甲基有可能形成C2H6而不是进一步解离。探讨了温度对TM@TTG上CH4脱氢反应的影响。结果表明，适度掺杂过渡金属可以显著调节TTG表面CH4的脱氢反应，为设计CH4分子分解过程提供了新的思路。
