In situ formation of nanocrystalline Ni(OH)2 in alkaline electrolyte explains superior capacitance and cycling stability of Ni3S2/NF electrodes Kh. A. Abdullin, M. T. Gabdullin, L. V. Gritsenko, Zh. K. Kalkozova, Zh. S. Kanatov, A. A. Markhabayeva, R. R. Nemkayeva, D. Zhapargali, M. Mirzaeian Scientific Reports, 2026 The free-standing Ni 3 S 2 electrode was fabricated via a simple one-step hydrothermal method at 160 °C through the sulfidization of nickel foam (NF). The as-synthesized samples exhibited X-ray diffraction (XRD) patterns and Raman spectra consistent with the formation of Ni 3 S 2 Although the XRD reflections of the Ni 3 S 2 lattice remained unchanged after short-term electrochemical activation in 3.5 M KOH electrolyte, the Raman spectrum evolved to resemble that of oxidized nickel species, indicating a surface transformation of the electrode under electrochemical conditions. Prolonged redox cycling of the electrode for more than 10,000 cycles resulted in noticeable modifications of the XRD pattern. In addition to the characteristic reflections of the Ni 3 S 2 phase, the formation of β-Ni(OH) 2 nanoparticles was observed, with an average crystallite size of approximately 2.8 nm, as estimated using the Scherrer equation. The resulting heterostructured Ni(OH) 2 /Ni 3 S 2 /NF electrode exhibited an areal capacitance of 4.1 C cm –2 at a current density of 20 mA cm –2 when evaluated in a three-electrode configuration. The electrode demonstrated progressively enhanced capacitance stability with continued cycling. Capacitance retention increased from 19% after the first 10,000 cycles to 41% after the second 10,000 cycles, 66% after the third 8,000 cycles, and ultimately 79% after the fourth 6,000 cycles. Taking into account the electrochemical activation occurring between cycling intervals, the overall capacitance retention reached 72% after more than 30,000 cycles. Although the electrode capacitance decreased during galvanostatic charge–discharge (GCD) cycling, it could be partially recovered through subsequent cyclic voltammetry (CV) activation. Concurrently, a broad XRD reflection attributable to the α-Ni(OH) 2 phase emerged, providing valuable insight into the structural evolution of the electrode and the underlying electrochemical energy-storage mechanism. The Ni(OH) 2 /Ni 3 S 2 /NF electrode aged through 10,000 GCD cycles was subsequently employed as the positive battery-type electrode in a hybrid supercapacitor, paired with an activated carbon negative electrode. The assembled device, with a Ni 3 S 2 /NF electrode area of 6 cm 2 , delivered an areal capacitance of 4.63 C cm –2 at a current density of 4 mA cm –2 and maintained 83.5% capacitance retention after more than 20,000 charge–discharge cycles.
Highly Sensitive Zinc Oxide Nanorods for Non-Enzyme Electrochemical Detection of Ascorbic and Uric Acids Lesya V. Gritsenko, Zhaniya U. Paltusheva, Dinara T. Tastaibek, Khabibulla A. Abdullin, Zhanar K. Kalkozova, Maratbek T. Gabdullin, Juqin Zeng Biosensors, 2026 In this study, an enzyme-free electrochemical sensor based on zinc oxide (ZnO) nanorods synthesized by the thermal decomposition of zinc acetate is presented. The suggested approach ensures simplicity, environmental friendliness, and scalability of the process without the use of an autoclave or high pressure. The morphology and structure of the samples are studied using SEM, TEM, XRD, Raman, FTIR, XPS, PL, and UV-Vis spectroscopy. It is found that heat treatment at 450 °C increases the degree of crystallinity, increases the size of crystallites, and reduces the concentration of surface defects, which leads to improved optical and electrochemical characteristics of the material. Beyond conventional sensitivity metrics, our study demonstrates that the selective detection of ascorbic acid (AA) and uric acid (UA) can be achieved by controlling the applied potential on a single ZnO electrode, an approach that leverages differences in redox energetics and surface interaction dynamics rather than complex surface functionalization. It is shown in this work that the synthesized ZnO samples subjected to heat treatment in air at 450 °C exhibit high sensitivity to ascorbic acid (9951.87 μA·mM−1·cm−2; LoD = 1.11 μM) at a potential of 0.2 V and to uric acid (5762.48 μA·mM−1·cm−2; LoD = 1.71 μM) in a phosphate buffer solution (pH 7) at a potential of 0.4 V with a linear range of 3 mM, offering a way to create simplified multicomponent electrochemical biosensors based on potential-controlled selectivity.
Dihydrazide-Mediated Crystal Engineering and Precursor Anti-Aging for Efficient and Stable Perovskite Solar Cells and Modules Hang Wei, Ruihao Chen, Yang Yang, Ruohao Wang, Kaiyu Wang, Shuyuan Wan, Haoze Lu, Zhiyuan Dai, Wei Hu, Lihao Fan, Anar Dosmukhambetova, Dilnaz Kadyrma, Yerzhan Mukhametkarimov, Zhanar Kalkozova, Zhe Liu, Hongqiang Wang Advanced Functional Materials, 2026 Commercialization of perovskite solar cells (PSCs) is hindered by challenges in crystallization control, long‐term operational stability, and precursor degradation. Here, a multifunctional molecule, isophthaloyl dihydrazide (BDH), is introduced to simultaneously address these issues in inverted PSCs. BDH facilitates preferential crystallization via dual‐site coordination with perovskite, resulting in improved crystallinity, suppressed non‐radiative recombination, and enhanced charge transport. Its carbonyl groups effectively passivate uncoordinated Pb2+ ions, while the hydrazide functionality suppresses iodide oxidation in both solution and solid‐state phases. This redox‐stabilizing effect significantly extends the ambient shelf life of perovskite precursor inks to four weeks without compromising device performance. Consequently, BDH‐modified devices deliver an impressive efficiency of 25.78%, retaining 94.6% of their initial value after 1000 h of maximum power point tracking and showing no degradation across nine light‐dark cycles. Notably, the mini‐modules (aperture area of 26.78 cm2) achieve a high efficiency of 22.30% and excellent stability.
New cobalt hydroxycarbonate-based material for highly sensitive enzyme-free glucose sensors Zh. K. Kalkozova, L. V. Gritsenko, U. A. Balgimbayeva, M. T. Gabdullin, Dan Wen, Kh. A. Abdullin Scientific Reports, 2025 Health monitoring with glucose sensors is essential for preventing various diseases and maintaining overall well-being. Among the numerous analytical methods used to measure glucose levels, electrochemical enzyme-free methods show high practical potential. Developing new materials for highly sensitive and stable enzyme-free sensors is of significant importance. This study presents hydroxycarbonates as a new class of materials for creating enzyme-free glucose sensors and demonstrates, for the first time, that nanostructured cobalt hydroxycarbonate is a promising candidate for effective sensor applications. Prepared using a simple one-step hydrothermal method, this material exhibited a sensitivity of 1950 µA cm−2 mM−1 with a detection limit (LOD) of approximately 30 µM and a linear range up to 3 mM glucose. In addition, the sensitivity of the sensor synthesized in a 0.1 M cobalt nitrate solution was found to increase by more than 3 times up to 6745 µA cm−2 mM−1 when only 2 mol% of zinc nitrate was added to the growth solution containing cobalt nitrate and urea during synthesis. This adjustment also significantly affects the lattice vibration spectrum and material morphology, reducing the average nanoparticle size from 30 nm to 7–8 nm. The sensors demonstrated high long-term stability when stored under normal conditions. These results highlight the significant potential of the new sensor material for the quantitative detection of glucose.
Composite Metal Oxide Nanopowder-Based Fiber-Optic Fabry–Perot Interferometer for Protein Biomarker Detection Ulpan Balgimbayeva, Zhanar Kalkozova, Kuanysh Seitkamal, Daniele Tosi, Khabibulla Abdullin, Wilfried Blanc Biosensors, 2025 In this paper, we present the development of a new semi-distributed interferometer (SDI) biosensor with a Zn, Cu, and Co metal oxide nanopowder coating for the detection of a kidney disease biomarker as a model system. The combination of nanopowder coating with the SDI platform opens up unique opportunities for improving measurement reproducibility while maintaining high sensitivity. The fabrication of sensors is simple, which involves one splice and subsequent cutting at the end of an optical fiber. To ensure specific detection of the biomarker, a monoclonal antibody was immobilized on the surface of the probe. The biosensor has demonstrated an impressive ability to detect biomarkers in a wide range of concentrations, from 1 aM to 100 nM. The theoretical limit of detection was 126 fM, and the attomolar detection level was experimentally achieved. The sensors have achieved a maximum sensitivity of 190 dB/RIU and operate with improved stability and reduced dispersion. Quantitative analysis revealed that the sensor’s response gradually increases with increasing concentration. The signal varies from 0.05 dB at 1 aM to 0.81 dB at 100 nM, and the linear correlation coefficient was R2 = 0.96. The sensor showed excellent specificity and reproducibility, maintaining detection accuracy at about 10−4 RIU. This opens up new horizons for reliable and highly sensitive biomarker detection, which can be useful for early disease diagnosis and monitoring using a cost-effective and reproducible sensor system.
A Facile Method for Synthesizing Cobalt Oxide Nanoparticles to Create a Highly Sensitive Non-Enzyme Glucose Sensor Zhanar K. Kalkozova, Ulpan A. Balgimbayeva, Maratbek T. Gabdullin, Lesya V. Gritsenko, Guoquan Suo, Khabibulla A. Abdullin Biosensors, 2025 In this study, an electrochemical non-enzymatic glucose sensor based on cobalt oxide was developed using a simple chemical bath deposition method. The as-synthesized material exhibited no significant sensitivity; the latter emerged only after subsequent electrochemical activation. To the best of our knowledge, this is the first report demonstrating the successful application of electrochemical activation to achieve enhanced sensitivity. An X-ray diffraction analysis confirmed that a single-phase Co2(OH)2(CO3) material was obtained immediately after synthesis, which was subsequently transformed into Co3O4 nanoparticles during electrochemical activation. SEM and TEM analyses revealed that the synthesized particles initially exhibited a nanorod structure, which evolved into a highly dispersed form after activation. The non-enzymatic glucose sensor based on the electrochemically activated material demonstrated excellent glucose sensitivity of 33,245 µA mM−1 cm−2 within the linear range of 0–0.5 mM, with a detection limit (LOD) of 5 µM. The starting material remained stable for over 12 months under ambient storage conditions and regained its high sensitivity following electrochemical activation.
