Nano‐sized bivalent metal complexes, specifically [M(L)2] with L = 2‐((E)‐((4,5‐dimethyl‐2‐(((E)‐4‐methylbenzylidene)amino)phenyl)‐imino)methyl)benzenethiol] (C23H22N2S) and M = Cu (II) (C1), Co (II) (C2), Ni (II) (C3), and Zn (II) (C4), underwent synthesis and subsequent characterization. Elemental analyses, infrared, NMR, mass, electronic, magnetic susceptibility, conductivity assessments, and X‐ray diffraction studies were used to assess our bivalent metal complexes. DFT studies were used to study the tautomeric equilibrium of the tridentate thio‐Schiff base ligand (HL), via the DFT\B3LYP method in connection with a 6–311G* correlation consistent basis set. Two tautomers, which are thione and thiol forms, were studied to estimate the predominant one. The metal formed four coordinated with the tridentate N2S donor thio‐Schiff base to form octahedral geometry complexes. The SEM, TEM, XRD, AFM, and EDX of the studied complexes unveiled distinct and strong diffraction peaks, signifying their crystalline nature and providing evidence of their particle sizes being within the nano‐size. The crystal sizes calculated for all complexes were determined to be ranging from 27.73 to 76.39 nm. The interactions between metal complexes and calf thymus DNA, and their potential for mimicking insulin activity, were investigated in a controlled lab setting by measuring their ability to inhibit alpha‐amylase. The antimicrobial potential of thio‐Schiff base ligand (HL) plus complexes (C1–C4) were tested. The viscosity and UV–Vis absorption determinations were utilized to assess the calf thymus DNA (CT‐DNA) interaction with the nano‐sized metal (II) chelates. Our flow cytometry data indicate significant levels of apoptosis and cell cycle arresting in both liver and breast cancer cell lines. [ABSTRACT FROM AUTHOR]

The shortage of fossil fuels and global warming are the two main issues facing the world today and these can be overcome by the usage of H2 as a sustainable energy. The study's primary objective is to fabricate an efficient electrocatalyst for electrochemical water splitting. This study uses CuS, Ni-doped CuS and Ni/CuS/S-g-C3N4 (NCS/SCN) composites for the electrochemical water-splitting. NCS/SCN composites were produced via the co-precipitation method with different S-g-C3N4 contents (10, 30, 50, 70, and 90 wt.%) to study the impact of S-g-C3N4 on the electrochemical water splitting performance of NCS. Characterization techniques SEM, EDX, FTIR, and XRD evaluated the electrocatalysts' size, shape, and morphology. Electrochemical studies were performed employing a three-electrode system using KOH as the electrolyte. Results from LSV, CV, and EIS show that the development of composite material NCS/SCN enhances the electrocatalytic water-splitting activity of NCS in 1 M KOH solution. Results show that NCS/50%SCN exhibits the best OER and HER and thus can be utilized as a commercial electrocatalyzer for water splitting. [ABSTRACT FROM AUTHOR]

This study addresses the hydrogen storage capabilities and mechanical, optoelectronic, and thermoelectric features of double perovskite hydrides A 2 FeH 6 (A = Be, Mg). The structural aspects suggest the cubic symmetry of studied hydrides. The formation enthalpy value calculation has confirmed the structures' thermal stability. The gravimetric ratios of Be 2 FeH 6 and Mg 2 FeH 6 hydrides are 7.50 wt% and 5.43 wt%, respectively. The desorption temperatures are predicted to be 230.32 K and 208.67 K, respectively. The mechanical and thermophysical characteristics have been elaborated, which demonstrate mechanical stability, higher stiffness, ductile behavior, and higher temperature stability of both materials. The examined electronic properties have revealed band gap values of 2.89 and 3.08 eV, respectively. The optical properties have been assessed to predict the appropriateness of these hydrides for deployment in photovoltaic systems. The thermoelectric characteristics have been evaluated to examine the carrier transport mechanism and efficiency for converting heat into electricity. Finally, the investigated properties and hydrogen storage capacity of these compounds suggest that they are suitable for hydrogen storage and have the potential to play a key role in many energy generation applications. The lift side shows the figure of merit with large values at room temperature, and the right side shows the hydrogen storage capacity.

Featured Application: The silent threat from the release of antimicrobial resistant genes into the environment from hospital and municipal sources, which is going unnoticed, and the existing techniques for remediation of ARG polluted waters have been highlighted. Additionally, prospective nano-based applications have been suggested. Antibiotic resistance is a major crisis that the modern world is confronting. This review highlights the abundance of different types of antibiotic resistance genes (ARGs) in two major reservoirs in the environment, namely hospital and municipal wastewater, which is an unforeseen threat to human lives across the globe. The review helps understand the current state of affairs and the whereabouts on the dissemination of ARGs in both these environments. The various traditional wastewater treatment methods, such as chlorination and UV treatment, and modern methods, such as electrochemical oxidation, are discussed, and the gaps in these technologies are highlighted. The need for the development of newer techniques for wastewater treatment with enhanced efficiency is urgently underscored. Nanomaterial applications for ARG removal were observed to be less explored. This has been discussed, and prospective nanomaterials and nanocomposites for these applications are proposed.

A significant amount of energy can be produced using renewable energy sources; however, storing massive amounts of energy poses a substantial obstacle to energy production. Economic crisis has led to rapid developments in electrochemical (EC) energy storage devices (EESDs), especially rechargeable batteries, fuel cells, and supercapacitors (SCs), which are effective for energy storage systems. Researchers have lately suggested that among the various EESDs, the SC is an effective alternate for energy storage due to the presence of the following characteristics: SCs offer high-power density (PD), improvable energy density (ED), fast charging/discharging, and good cyclic stability. This review highlighted and analyzed the concepts of supercapacitors and types of supercapacitors on the basis of electrode materials, highlighted the several feasible synthesis processes for preparation of metal oxide (MO) nanoparticles, and discussed the morphological effects of MOs on the electrochemical performance of the devices. In this review, we primarily focus on pseudo-capacitors for SCs, which mainly contain MOs and their composite materials, and also highlight their future possibilities as a useful application of MO-based materials in supercapacitors. The novelty of MO's electrode materials is primarily due to the presence of synergistic effects in the hybrid materials, rich redox activity, excellent conductivity, and chemical stability, making them excellent for SC applications.

This article systematically presents new approaches and techniques for preparing these compounds. It also highlights the biological importance of benzo[f][1,3,5]triazepine derivatives, which have been used as drugs for treating nervous system diseases. This review aims to provide researchers with the necessary information to create and develop new derivatives of these compounds as quickly as possible. [ABSTRACT FROM AUTHOR]
