Cobalt and nickel oxides with large theoretical capacitance, high redox activity and low-cost features are widely applied as electroactive material of battery supercapacitor hybrids (BSH) to reduce energy consumption and create renewable energy. Synthesizing cobalt and nickel oxides using zeolitic imidazolate framework 67 (ZIF67) can enhance conductivity and electroactivity and maintain surface area and porosity of ZIF67. Structure directing agent (SDA) can control morphology and improve electrochemical performance. It is attractive to apply SDA for controlling morphology of oxidized ZIF67 and achieving excellent energy storage. In this work, ammonium tetrafluoroborate (NH4BF4) is firstly applied as SDA to synthesize ZIF67 derivative, which is then annealed to form leaf-like cobalt and nickel oxides as electroactive material. The optimal oxidized ZIF67 derivative shows a larger specific capacitance (CF) of 828.9 F/g than those of 519.9 and 5.0 F/g respectively for the oxidized ZIF67 and pristine ZIF67 electrodes, due to preferable leaf-like structure and (311) facet for the former case. A BSH with oxidized ZIF67 derivative positive electrode and graphene negative electrode shows maximum energy density of 10.2 Wh/kg at 357 W/kg, and CF retention of 91% and Coulombic efficiency of 97% after 10,000 cycles. The novel SDA of NH4BF4 is expected to design other efficient electroactive materials for effective energy storage. © 2023 Elsevier Ltd

Owing to the advancement of bioactive materials, bioactive glasses (BGs) are progressively being recognized as promising choices in fields of bone and tissue engineering with their superior properties such as bioactivity and biocompatibility. However, their applications are limited by the fact that the material itself does not possess antibacterial properties. To address this limitation, antibacterial BGs with silver-zinc co-dopant were proposed and successfully synthesized via the one-step spray pyrolysis technique in this work. The phase composition, chemical composition, surface morphology, and nanoscale structures of the obtained BG specimens were characterized using X-ray diffraction, energy dispersive spectroscopy, scanning electron microscopy, and transmission electron microscopy. Moreover, in-vitro bioactivity was assessed through immersion of the SBF solution, while the in-vitro antibacterial property was examined using Escherichia coli bacteria. Meanwhile, the viability of MC3T3-E1 osteoblast cells was evaluated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Finally, the results showed positive effects of zinc addition, and the influence of silver and zinc dopants on the in-vitro bioactivity, antibacterial property, and cell viability were discussed. © 2024 The Author(s).

Bisphenols threaten human health and sensitive detection is crucial. The present study aims to develop ternary composites of copper metal-organic framework (Cu-MOF) with Au[sbnd]Ag microstructures. The composite structure was formed by a galvanic displacement reaction and confirmed using SEM. A binder-free catalyst was used to study the electrochemical redox reaction of bisphenol A (BPA) and bisphenol S (BPS);an irreversible cyclic voltammetric signal at +0.70 V and + 0.91 V (vs. Ag/AgCl), in the dynamic range of 20 nM to 2.0 mM, and 10 nM to 1.0 mM, with limits of detection of 2.9 nM, and 3.2 nM (S/N = 3) was obtained. Practical analysis was applied to frozen tomatoes, tuna fish, milk powder, PET bottles, raw milk, and urine samples with a recovery rate of 94.00–100.80% (n = 3). Voltammetric results were validated using HPLC detection with high precision. The sensor is a promising alternative platform for measuring BPA in food samples. © 2024

Glucose level surveillance in mankind is considered the greatest need of recent times to achieve healthy lifestyle goals due to its health-related concern for humans. To fulfill the need, Nickel-based compounds emerge with excellent bio-mimic properties. However, due to the poor electrical properties of oxides and hydroxides of Ni, developing a supporting base that can enhance electron transportation is mandatory. The present work is dedicated to non-enzymatic glucose detection by electrochemical means on the Ni3N thin film on an Indium-doped Tin Oxide (ITO) substrate as a working electrode in an alkaline medium. The Ni3N films use HiPIMS as a deposition technique due to its high ionization rate of sputtered species and dense plasma which helps the Ni ions to react with nitrogen in the formation of a perfect Ni3N phase, and it is a green process that can contribute to sustainable manufacturing. Ni3N thin film deposited at a 60 % N2 flow ratio shows the largest crystallinity and catalytic properties, which helps this modified electrode to have significant potential for glucose detection. The Ni3N modified electrode acquires a lower linear range of 0.001–1.25 mM with sensitivity and Limit of Detection (LOD) of 337.46 µAmM–1cm−2, and 0.78 µM, respectively, and a higher linear range of 1.25–7.3161 mM with a sensitivity of 158.58 µAmM–1cm−2. The amperometric measurements reveal the fast response of the electrode towards glucose detection at 2.46 secs. The key measures of the electrode according to the corresponding measurements are satisfactory selectivity, reproducibility, repeatability, and operational stability. The modified electrode shows a significant response for real samples such as commercially available honey, apple juice, and biological fluids. © 2024 Elsevier B.V.

Glass coating is an important thermal insulation technique used in the aerospace industry that serves as a thermal protection system (TPS) to protect the inner layer at elevated temperatures. This work highlights the superb mechanical and thermal properties of the B2O3-SiO2 glass systems as a surface coating for space shuttle. In the B2O3-SiO2 system, the glass transition temperature raises from 650 °C to 750 °C with increasing SiO2 content and devitrification of the α-cristobalite phase. The Al2O3 addition in B2O3-SiO2 glass can increase the glass transition temperature from 750 °C to 1000 °C and inhibit the α-cristobalite phase. The phase transition from an unstable α-cristobalite phase to an amorphous phase was achieved at 10 wt% Al2O3-added specimens. This study demonstrates that the Al2O3-B2O3-SiO2 glass (ABS glass) exhibits thermally stable behavior, making it an effective thermal barrier coating at elevated temperatures. © 2023

Water contamination is a serious environmental issue posing a significant global challenge. Roxarsone (ROX), a widely used anticoccidial drug is excreted in urine and feces, potentially disrupting natural habitats. Therefore, rapid and cost-effective ROX detection is essential. In this study, we developed a 2D sheet structure of zinc molybdate decorated on MXene (ZnMoO4/MXene) for detecting ROX using electrochemical methods. The materials were characterized using appropriate spectrophotometric and voltammetric techniques. The ZnMoO4/MXene hybrid exhibited excellent electrocatalytic performance due to its rapid electron transfer rate and higher electrical conductivity. The ZnMoO4/MXene-modified GCE (ZnMoO4/MXene/GCE) showed a broad linear range with high sensitivity (10.413 μA μМ−1 cm−2) and appreciable limit of detection (LOD) as low as 0.0081 μM. It also demonstrated significant anti-interference capabilities, excellent storage stability, and remarkable reproducibility. Furthermore, the feasibility of utilizing ZnMoO4/MXene/GCE for monitoring ROX in water samples was confirmed, achieving satisfactory recoveries. © 2024 Elsevier Ltd

The glass coating is an important technique in the aerospace industry as a thermal insulation role to protect the inner layer to form a thermal protection system (TPS) at elevated temperature. The results show an increase of the glass transition temperature (from 650 °C to 750 °C) in B2O3-SiO2 systems with increasing SiO2 content and the devitrification of the α-cristobalite phase. The Al2O3 additive in B2O3-SiO2 glass can increase the glass transition temperature from 750 °C to 1000 °C, and also inhibit the α-cristobalite phase. The transformation from the unstable α-cristobalite phase to the amorphous phase occurs at specimen with 10 wt% Al2O3 addition. Microstructure characterization shows the flat morphology without cracks on the surface. This study demonstrates that the Al2O3- B2O3-SiO2 glass has a thermally stable behavior which can be used as an effective thermal barrier coating at elevated temperature. © 2023, The Authors.

Background: Fungicides, like carbendazim, have effects on male fertility. There have been sufficient studies conducted on certain chemical compounds to indicate a selective action at the epididymis level. To prevent contamination of food products with fungicides, most of the governments have established rules for the use of fungicides. However, even though this type of fungicide is primarily used in agriculture. More probably, it's contaminated with fruits and vegetables. In particular, carbendazim is one of the major fungicides in the agricultural usage Methods: This research work developed a europium vanadate (EuVO4) nanoparticle decorated carbon nanofiber (CNF) composites by hydrothermal-sonochemical approach. Based on this composite, Carbendazim sensing is developed through electrochemical oxidation based on EuVO4/f-CNF modified Glassy Carbon Electrode (GCE). By combining EuVO4 and f-CNF with the GCE, carbendazim detection can be highly effective. GCEs are rigid, making them ideal for depositing EuVO4/f-CNF, while their expansive surface area makes it possible to immobilize a greater amount of EuVO4/f-CNF, which could increase the Carbendazim sensing ability of the resulting modified GCEs with EuVO4/f-CNF. Main Findings: : The carbendazim sensing was actualized by the electrocatalytic oxidation of carbendazim on the composite modified electrode, and it is demonstrating a linear range of 0.125 to 23.875 – 33.81 to 131.375 µM with a remarkably limit of detection of 0.00612 µM. The EuVO4/f-CNF /GCE also showcased an excellent degree of stability, retaining 96.5 % of its initial activity even after 30 days. This research highlights the potential of EuVO4/f-CNF modified GCEs as robust, and efficient platform for the carbendazim detection under electrochemical approach. © 2024 Taiwan Institute of Chemical Engineers

In this study, chrysanthemum flower-like nickel oxide – cobalt oxide (NiO-CoO) nano hybrid was generated hydrothermally and explored as an anode in lithium/sodium-ion batteries. Various characterization techniques were employed to analyze the crystal structure, chemical composition and morphology of the synthesized NiO-CoO nano hybrid. Electrochemical studies including cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) and electrochemical impedance spectroscopy (EIS) were conducted to evaluate the lithium-ion and sodium-ion storage performances of the NiO-CoO nano hybrid electrode. It turned out that the lithium-ion battery half-cell constructed in the form of CR-2032 coin cell containing the NiO-CoO hybrid anode achieved a high specific capacity of 739 mA h g-1 at 0.1C-rate showed consistent 100% Coulombic efficiency over 100 charge-discharge cycles. Additionally, the sodium-ion battery performance was also investigated, delivering a specific capacity of 340 mA h g-1 at 0.1C-rate with stable cycle life over 100 cycles. Interestingly, a full-cell lithium-ion battery (NiO-CoO|1M LiPF6|LiCoO2) was assembled for the first time employing the NiO-CoO nano hybrid as anode. The fabricated CR-2032 coin-type LIB full-cell exhibited a specific capacity of 112 mA h g-1 at 0.1C-rate. Further the full cell LIB was demonstrated for practical applications such as powering commercial LED bulbs and a temperature sensor. The fabricated full-cell sustained illumination of a green LED bulb for over 5 hours on a single charge. The fascinating flower-like morphology of the NiO-CoO hybrid led to better interaction with the electrolyte and offered short diffusion path as well as efficient conversion/re-conversion reactions which in turn led to high charge storage. © 2024, The Authors.

The rapid fabrication is described of binary electrocatalyst based on a highly porous metal–organic framework with zirconium metal core (Zr-MOF) decorated over the graphitic carbon nitride (g-C3N4) nanosheets via facile ultrasonication method. It is used for the robust determination of antipsychotic drug chlorpromazine (CLP) from environmental samples. The electrochemical behaviour of 2D Zr-MOF@g-C3N4 was characterized by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) studies. The crystalline and porous nature of the composite was characterized by XRD and SEM analysis. The functional groups and surface characteristics were investigated by FT-IR, Raman and XPS. The major electrochemical properties of the Zr-MOF@g-C3N4 composite towards CLP detection were analyzed by CV, chronocoulometric (CC), chronoamperometric (CA) and differential pulse voltammetry (DPV) techniques. The composite exhibits a low detection limit (LOD) of 2.45 nM with a linear range of 0.02 to 2.99 µM and attractive sensitivity for CLP. The sensor system shows higher selectivity towards the possible interferences of CLP drug and exhibits better repeatability and stability. Finally, the fabricated sensor system shows a high recovery range varying from 96.2 to 98.9% towards the real samples. The proposed electrochemical probe might be a promising alternative to the prevailing diagnostic tools for the detection of CLP.
