The synthesis and characterization of CeO₂/MnFe₂O₄ nanocomposite is significant due to its potential uses in various sectors, including environment and energy storage. This nanocomposite, created through calcination at 600 °C, has received a lot of interest. However, worries about potential cytotoxicity have encouraged studies into its safe use in biological systems. This study investigates the material’s cytotoxic properties to determine its impact on cell health. Electrochemical testing revealed good capacitance performance within the 0–0.5 V potential window, with a specific capacitance (Cs) of 76 F/g at a current density of 0.25 A/g, making it a prospective candidate for supercapacitor (SC) development. Despite the higher current density of 5 A/g, the electrode maintained 81.28 % of its capacitance retention. These findings highlight the nanocomposite’s potential in SC applications. Furthermore, cell viability studies with normal mouse muscle fibroblasts (BLO-11) and murine colorectal cancer cells (CT-26) demonstrated high biocompatibility, with cell survival rates exceeding 82 %. These findings highlight the need to assess nanocomposite safety for potential biological applications.

For the first time, a novel solid adsorbent of silicone rubber modified with thiourea and methyl methacrylate polymeric material was developed for Mn(II) and Fe(III) adsorption from wastewater.

Since these two elements Mn(II) and Fe(III) represent a very big problem in the drinking water resulting from treatment from the technology station during some stages, in this way they are used again in agriculture and also for human use. Before crosslinking the polymer chains, methyl methacrylate (as partial hydrogen bonding cross-linking sites) quickly interacted with thiourea groups, resulting in rapid curing. The polymeric adsorbent’s structure was investigated by XRD, FTIR, SEM, EDX, and Brunauer, Emmett, and Teller analyses. The polymeric material’s adsorption efficiency for Mn(II) and Fe(III) from wastewater has been studied by XRF. The adsorption factors (including contact time, pH, temperature, and metal concentration) were extensively examined. The adsorption optimized conditions were elucidated to study the structure–property relationship. The material’s maximum adsorption capacity was 14 for Mn(II) and 29 mg/g for Fe(III). Reusability studying is 3 stage, A pseudo-second-order mechanism was recycled in the adsorption of Mn(II) and Fe(III) of wastewater, which followed the Langmuir isotherm model. The obtained thermodynamic factors (such as ΔH°, ΔG°, and ΔS°) demonstrated that Mn(II) and Fe(III) were adsorbed exothermically and spontaneously. A novel porous silicone-thiourea-methyl methacrylate blend showed outstanding adsorption efficiency for Mn(II) and Fe(III) adsorption.

CeO₂ with porous nanosheet structure was prepared by changing the calcination environment. The prepared CeO₂ nanosheets had high specific surface area and porosity, which was suitable for supporting other active components. By the same synthesis conditions, a small amount of Cu and Ag was introduced into the synthesis system of CeO₂ nanosheets respectively. The introduction of Cu or Ag did not significantly change the morphology of the prepared CeO₂ nanosheets, but it notably improved the catalytic activity for CO oxidation. Therefore, considering the significant improvement of catalytic performance caused by the single doping of Cu or Ag, (Cu, Ag) were co-doped into the CeO₂ system. The analysis of physical structure (XRD, BET, SEM and TEM) and surface chemical properties (XPS, Raman and H₂-TPR) showed that the (Cu, Ag) co-doping not only improved the dispersion of Cu and Ag species on the catalyst surface, but also increased the Ag⁰ and oxygen vacancies on the catalyst surface. The smaller Ag⁰ crystallite size and the abundant oxygen vacancies made the catalyst easier to activate O₂ at low temperature, so the activity of the catalyst at low temperature was significantly enhanced compared to the CeO₂ singly doped with Cu or Ag. At the same time, the high dispersion of Cu-Ag species was conducive to electron transfer between Cu-Ag species and CeO₂ support.

Malachite green (MG), a dye in wastewater, pollutes the natural environment, and it is difficult to eliminate dyes from aquatic systems. MgAlLDH-magnetite humic acid (Mg3Al@M2HA) was prepared for MG adsorption via coprecipitation and hydrothermal methods. The adsorption was performed using the batch adsorption method at the pH of the point of zero charge (8.33), with an optimum contact time of 120 min and a maximum concentration of 100 mg/L of MG. Furthermore, the pseudo-second-order and Langmuir models were better fitted to the kinetic and isotherm models, respectively. The maximum monolayer adsorption capacity for MG on Mg3Al@M2HA at 313 K was 113.6 mg/g. The calculated thermodynamic parameters (

Moreover, the ΔH was less than 40 kJ/mol, confirming that the combination of MG with Mg3Al@M2HA was due to the physisorption with electrostatic interaction, hydrogen bonding, and π–π interaction. Recycling experiments showed that the MG removal rate was 82.55 % after 5 cycles. This study provides new insights into Mg3Al@M2HA and its potential applications for MG adsorption.

Polymers have consistently proven to be a convenient option for enhancing the catalytic characteristics of Molybdenum diselenide. Opting for the correct choice facilitates permanent exfoliation, enhances the available space on the surface, and improves the adaptability of the dichalcogenide. In this study, the researchers utilized two highly advantageous conducting polymers, namely poly(3,4-ethylenedioxythiophene) (PD) and polyaniline (Pn), to enhance the efficiency of MoSe₂ in the dye-sensitized solar cell. Optimal percentage is crucial for achieving a uniformly distributed, consistent, and well-separated system that improves the electrocatalytic sites and conductive properties while providing flexibility through PD. Furthermore, PD is employed independently, without the assistance of a secondary polymer. The produced composite’s purity, morphology, and surface area were examined using X-ray diffraction, field emission scanning electron microscopy, and Brunauer-Emmett-Teller analysis. Electrochemical investigations reveal that composites display outstanding electrocatalytic performance, rapid electron transfer rate, and enhanced current flow compared to unadorned materials. The devices’ photovoltaic performance was assessed by employing a typical solar simulator set at an intensity of 1 Sun (AM 1.5 G). The electrochemical investigation of the fabricated hybrid system demonstrates the efficacy of a high level of electrocatalysis and excellent device performance with a photoconversion efficiency of 8.65 %. This makes it an effective and affordable choice for a counter electrode in DSSCs.

The growing need for effective gas detection technologies has led to significant advancements in the development of gas sensors. This study introduces a novel Poly(o-toluidine) (POT)/Titanium dioxide (TiO₂) nanocomposite sensor for sulfur dioxide (SO₂) detection, demonstrating remarkable improvements in sensitivity, selectivity, and response/recovery times. The POT/TiO₂ nanocomposite sensor exhibits a threefold enhancement in sensitivity compared to pure POT, achieving a response of 186 at 50 ppm SO₂ at room temperature, a significant improvement over previous high-temperature-based SO₂ sensors. Additionally, the sensor demonstrates excellent repeatability and stability over 35 days, making it a promising candidate for industrial and environmental monitoring. The synergistic interaction between POT and TiO₂ enhances charge transfer and gas adsorption, resulting in faster and more reliable SO₂ detection and presenting an innovative solution for practical gas sensing applications.

The geometry and conformations of all published single crystal X-ray (SCXRD) structures of cyclic P₂N₂-ligands (1,5-diaza-3,7-diphosphacyclooctanes) were analyzed. It was found that the cyclic P₂N₂-ligands exist in two fundamentally different structural motifs with relatively high or low angles between phosphorus lone pairs. The interdependence of the angle between phosphorus lone pairs, distance between phosphorus atoms, distance between nitrogen atoms and endocyclic CNC angles was demonstrated via the correlation plots of these parameters. The detailed analysis of XRD structures accompanied with the DFT calculations allowed to establish that the endocyclic CNC angle, which is determined by the hybridization of N-atom, is the main driving force for the structural variations. These data are demonstrating that the P₂N₂-ligands are the “breathing” cycles, which are able to increase or decrease the P^…P-distances accompanied with rotation of phosphorus atom affecting the angle between phosphorus lone pairs. According to the obtained massive of data it was hypothesized that the N-alkyl substituted P₂N₂-cycles preferably forms the P,P-chelate complexes, whereas the N-aryl substituted ligands are able to form both P,P-bridged and P,P-chelate complexes. All of the foundations provide the explanations for the behavior of the P₂N₂-ligands during the coordination with transition metals.

Supercapacitors (SCs), including electric double-layer capacitors (EDLCs), pseudo-capacitors, and hybrid capacitors, are vital for energy storage. EDLCs use porous carbon materials, while pseudo-capacitors rely on oxide redox reactions. Hybrid SCs combine these methods to enhance cell potential and energy density. This review examines the electrochemical characterization of hybrid SCs, focusing on cyclic voltammetry (CV). It discusses material selection, cell setup, initial CV results, and full-cell CV characterization, emphasizing curve shape, voltage-current behavior, diffusion, and performance. The review also explores the impact of mechanical stress on CV and highlights the need for standardized CV protocols. Although hybrid SCs offer rapid charging and high energy storage, CV research from 2019 to 2024 remains limited and sometimes contradictory. The review underscores CV’s role in understanding hybrid SCs and suggests future research to address gaps and improve optimization.

Organic solar cells are a class of photovoltaic technologies that have complemented the currently available inorganic silicon-based solar cells. The increased energy consumption requirements from industries and households have led to an increased need to improve the current conversion efficiency of photovoltaic technology. The incorporation of a magnetic field into the active layer of organic solar cells has been established for improved conversion efficiency. The current review outlines the recent progress and strategies that have been employed in engineering the transport properties of magnetic-based organic solar ce. The main contributing factors to the enhanced performance of the reported organic solar cells are attributed to the rate increase of the intersystem crossing of singlet to the triplet states. The review discusses the current challenges hampering the commercialization of the technology and the prospect of magnetic field-based organic PV technology.

The esterification of 4-oxopentanoic acid (OP) to amyl-4-oxovalerate (AV) is a green, efficient, and cost-effective process. However, traditional methods for catalyst selection and optimization are inefficient and costly, failing to meet the evolving demands of the fuel industry. In this study, we synthesized a WO₃/FePO₄ (0.3:1 mass ratio) catalyst for the esterification of OP with amyl alcohol (AA) via facile hydrothermal and wet impregnation methods and characterized it with various physio-chemical techniques. The WO₃/FePO₄ catalyst, having larger total acidic sites (1.5 mmol/g), moderate surface area (72 m²/g), void size (3.4 nm), and spherical morphology, exhibited superior catalytic performance, achieving a 92 % OP conversion and 100 % AV selectivity, compared to the FePO₄ catalyst at 100 °C in 3 h with a catalyst dosage of 50 mg. Moreover, the WO₃/FePO₄ catalyst maintains its activity after six recycling cycles. The esterification of OP with different alcohols was also explored. Reaction parameter impacts were examined, and pseudo first-order kinetics revealed that activation energy of 12.65 kJ/mol.

However, traditional methods for catalyst selection and optimization are inefficient and costly, failing to meet the evolving demands of the fuel industry. In this study, we synthesized a WO<sub>3</sub>/FePO<sub>4</sub> (0.3:1 mass ratio) catalyst for the esterification of OP with amyl alcohol (AA) via facile hydrothermal and wet impregnation methods and characterized it with various physio-chemical techniques. The WO<sub>3</sub>/FePO<sub>4</sub> catalyst, having larger total acidic sites (1.5 mmol/g), moderate surface area (72 m<sup>2</sup>/g), void size (3.4 nm), and spherical morphology, exhibited superior catalytic performance, achieving a 92 % OP conversion and 100 % AV selectivity, compared to the FePO<sub>4</sub> catalyst at 100 °C in 3 h with a catalyst dosage of 50 mg. Moreover, the WO<sub>3</sub>/FePO<sub>4</sub> catalyst maintains its activity after six recycling cycles. The esterification of OP with different alcohols was also explored.
