The increase of antibiotic-resistant strains has necessitated the generation of antibacterial agents that do not induce microbial resistance. The present study was conducted to evaluate the antibacterial effect of copper-coated carbon nanotubes (Cu/CNTs) synthesized by plasma-enhanced chemical vapor deposition (PECVD) on two strains of gram positive (Staphylococcus aureus) and gram negative (Escherichia coli) bacteria. First, the PECVD method was used to deposit carbon nanotubes (CNTs) on high-resistivity silicon wafers previously decorated with nickel catalyst by an electron beam gun. These nanotubes were then coated with copper thin films (Cu, 0– 60 nm) in a vacuum evaporator using the Direct Current (DC) Magnetron Sputtering method. The morphology of PECVD-grown Cu/CNTs was investigated by scanning electron microscope (SEM) and transmission electron microscope (TEM). The antibacterial properties of as-synthesized Cu/CNTs against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) were determined using Standard Plate Count (SPC). The results showed that increasing the coating thickness of Cu/CNTs had intensified their antibacterial activity. The SEM and TEM images confirmed the morphological modification of the samples after coating with copper.

The generation of a low HOMO-LUMO energy gap makes organic polymer-based composites an important class of materials with outstanding catalytic efficiency. The present work describes the simple and direct synthesis of an excellent photocatalyst, PC (C26H16NO7S)n via doping of erythrosine-B dye on sulfone infused poly(2-amino thiophenol) assembly (PA, (C6H4NO2S)n). The O 1 s spectrum displays peaks at 531.8 eV and 533.3 eV, representing the O=C and O–C groups of the in-situ generated fluorescein loaded on PA surface. Through absorption study (Tauc’s plot), the optical band gap (Eg) for polymer PA (2.9 eV) and photocatalyst PC (2.1 eV) has been calculated. Further, due to the efficient absorbance in the range of 400–600 nm with a low optical band gap, the applicability of the catalyst, PC has been checked in photocatalytic C–H activation in thiophene, and the generation of C–C bond with p-nitro aryldiazonium salt.

After extensive computations, novel trinitro compounds, triethyl ammonium 2,4,6-trinitro phenoxide (TEA-TNP) and tetramethyl guanidinium 2,4,6-trinitro phenoxide (TMG-TNP), are designed, synthesized, and identified. The Geometrical parameters, electronic properties, and spectroscopic analysis have been investigated by comparison of theoretical and experimental methods. Spectrum features that include IR and Raman have been calculated, and 1H and 13C NMR spectra are compared to experimental data. Electronic analysis has been investigated through NLO, FMO, UV-Vis, NBO, and MEP calculations. B3LYP/6-311++G(d,p) is highly successful and dependable for predicting ionic liquid stability, electrical characteristics, and spectroscopy. Both TEA-TNP and TMG-TNP are introduced as suitable candidates for NLO material. TMG-TNP with greater nucleophilicity (N) is a noncorrosive lubricant additive that reduces friction and wear for tribological performance.

Nowadays, the dilemma of drug resistance to antibacterial strains is of huge concern. Among the bacteria, Escherchia coli (E. coli) is the major pathogen, which is found in human and other animals. It is responsible for variety of severe diseases. A variety of commonly used antibiotics such as amoxicillin, gentamycin, etc and fluid replacement method are the suggested treatments for the infections caused by E. coli. In a study, it was established that the metal-based heterocyclic drugs demonstrated a different mode of action compared to the commonly used heterocyclic antibacterial drugs. Coumarin, an oxaheterocycle, is a privileged scaffold in medicinal chemistry. Metal complexes of coumarin-derived Schiff’s bases exhibit a broad range of pharmacological activities. Therefore, in the present review article, we have focused on the synthesis of metal complexes of coumarin derived Schiff’s bases as well as their respective Schiff’s base ligands and their antibacterial activities against the gram-negative bacterium E. coli.

Water pollution caused by antibiotics is one of the major challenges in the world today. The current research aims to investigate the effect of the Photo-Fenton process in removing indomethacin antibiotics from aqueous solutions. This experiment-based study was conducted on a laboratory scale and discontinuous manner. The influential variables affecting the removal efficiency of indomethacin include initial antibiotic concentration, pH, time, hydrogen peroxide concentration, and iron ion. The study was conducted base on standard methods (APHA, AWWA, CFWP, 2005). The Design Expert software was used to analyze the effect of independent variables on the removal efficiency of indomethacin antibiotics in the Photo-Fenton process (UV/H2O2/Fe2+) using response surface methodology (RSM) and central composite design (CCD). To ensure the repeatability of the results, each experiment was repeated three times and the reported the average. The results showed that the optimal removal conditions for indomethacin antibiotics were pH = 4, H2O2 oxidant concentration = 50 ppm, Fe2+catalyst concentration = 50 ppm, time = 75 minutes, and initial antibiotic concentration = 20 ppm, with a removal efficiency of 91.03% . The variables of initial antibiotic concentration, H2O2 concentration, and pH had the greatest impact on the removal efficiency of indomethacin. The results of this study indicate that under optimal conditions, more than 90% of indomethacin antibiotics can be removed from aqueous solutions using the Photo-Fenton process, which is a significant result for removing this pharmaceutical pollutant from aquatic environments.

A porous, low-cost, organic, amorphous and carbon-nitride functionalized polymer was synthesized using melamine and 5-bromo-2-thiophenecarboxaldehyde. One-pot polycondensation method was opted, to yield hyper-crosslinked polyaminal network which was used for the detection of NaOCl and Hg2+. Reaction proceeds in single step without addition of any catalyst and gives promising yield. The authenticity of the synthesized polymer MB was established using X-Ray photoelectron spectroscopy (XPS), Fourier-transform infrared spectroscopy (FT-IR) and Energy-dispersive spectroscopy (EDS). However, the morphology and thermal stability of MB was studied using X-Ray diffraction (XRD) & Scanning electron microscopy (SEM) and Thermogravimetric analysis (TGA) & Differential thermal analysis (DTA) respectively. BET studies were carried out to analyze the porous structure of MB. The pore diameter is centred at 6.2851 nm with specific surface area of 24.348 m2 g–1 and pore volume of 0.038258 cm3 g–1. The TGA curve showed that it has a good thermal stability (250°C). The synthesized compound was checked for its sensing behaviour with different analytes (metal ions: Cu2+, Cr2+, Mg2+, Cd2+, Mn2+, Zn2+, Pb2+, Hg2+; acids: HCl, H2SO4, HNO3 and ROS: t-BuOOH, KO2, NaOCl) in deionized water and was found to show significant change in intensity with NaOCl and Hg2+. The change in absorption spectra was observed at varied concentrations of NaOCl and Hg2+ solutions in deionized water using UV-Vis. Spectrophotometer.

In this search organic peroxide has been studied for its potential biological activities in various fields, including medicine and biotechnology. Molecular docking studies have been conducted to predict the binding between organic peroxide and certain biological targets, such as the breast cancer receptor 3hb5-oxidoreductase and the prostate cancer mutant 2q7k-Hormone. The docking results indicate potential interactions between peroxide and these targets. In addition to its potential cytotoxic activity, organic peroxide has been investigated for its antidiabetic activity. The docking results suggest that peroxide binds to the active site of enzymes involved in diabetes, such as α-amylase, pancreatic lipase, and β-glucosidase, with low binding energies. This indicates a potential role for peroxide in the treatment of diabetes. Furthermore, the interaction between peroxide and the antioxidant protein IHD2 (2HCK) has been explored. These computational studies suggest a possible pharmacological role for peroxide in the treatment of Helicobacter pylori (H. pylori) infection. The docking energy between peroxide and Helicobacter pylori adhesin HopQ type I bound to the N-terminal domain of human CEACAM1 indicates that peroxide could be a potential target to inhibit H. pylori infection. It’s important to note that these findings are based on computational methods and molecular docking studies. Further research, including in vitro and in vivo experiments, would be necessary to validate these findings and fully understand the potential benefits and limitations of peroxide in these applications.
在这项研究中，人们对有机过氧化物在医学和生物技术等多个领域的潜在生物活性进行了研究。为了预测有机过氧化物与某些生物靶标（如乳腺癌受体 3hb5-oxidoreductase 和前列腺癌突变体 2q7k-Hormone）的结合情况，进行了分子对接研究。对接结果表明，过氧化物与这些靶标之间存在潜在的相互作用。除了潜在的细胞毒性活性外，有机过氧化物还被研究用于抗糖尿病活性。对接结果表明，过氧化物能以较低的结合能量与α-淀粉酶、胰脂肪酶和β-葡萄糖苷酶等糖尿病相关酶的活性位点结合。这表明过氧化物在治疗糖尿病方面具有潜在作用。此外，还探讨了过氧化物与抗氧化蛋白 IHD2 (2HCK) 之间的相互作用。这些计算研究表明，过氧化物在治疗幽门螺旋杆菌（H. pylori）感染方面可能具有药理作用。过氧化物与人 CEACAM1 N 端结构域结合的幽门螺旋杆菌粘附素 HopQ I 型之间的对接能表明，过氧化物可能是抑制幽门螺旋杆菌感染的潜在靶点。值得注意的是，这些发现是基于计算方法和分子对接研究得出的。要验证这些发现并充分了解过氧化物在这些应用中的潜在益处和局限性，还需要进一步的研究，包括体外和体内实验。

According to the structure/property characteristics of polyacids, the design and synthesis of new inorganic organic hybrid materials based on POMs is of great significance for the rapid and effective removal of pollutants in wastewater. In addition, many researchers have synthesized a large number of POMs-based inorganic organic hybrid compounds with organic cations as templates. Based on the above background, in this article, a new supramolecular compound named o-[C20H18N2O4][Mo8O26]0.5.H2O was obtained through hydrothermal method by reacting 1, 2-bis[4-nitrile-pyridine)-N-methylene]phenyldibromide (L1) with (NH4)6Mo7O24.4H2O. The compound was characterized by IR, PXRD, and single crystal X-ray analysis. Single crystal X-ray analysis shows that the compound consists of a [β-Mo8O26] 2–, a dicarboxylic acid chelating ligand and a water molecule. This compound exhibits good catalytic activity towards MB. The degradation rate of MB by photocatalysis of compound 1 was 75.2% . The novelty of this work lies in the synthesis of a cyano-hydrolyzed ligand and the high efficiency of MB degradation of the compound.
