Abstract Brassica is one of the crops sensitive to low copper supply, leading to Alternaria blight. The present study reflects the synthesis of myco-derived copper oxide (M-CuO) nanoparticles (NPs) from Trichoderma asperellum and investigates their effect against Alternaria blight of Brassica in two soil types, alluvial and calcareous. Foliar applications of different treatments were used to treat plants: T1 (mancozeb@0.2%), T2 (propiconazole@0.05%), T3 (T. asperellum filtrate), T4 (M-CuO NPs), T5 chemically synthesized (C-CuO NPs), and T6 bulk phase (BP-CuO @25, 50, 100, 150, and 200 ppm) of each in twice such as protectant and curative method under pot experiments. M-CuO NPs in two protective sprays exhibit up to 75% disease suppression in alluvial soil, compared to 68.9% suppression in curative spray at 200 ppm. Maximum seed yield and seed number were obtained, 1.95 g/plant and 850 seeds/plant in alluvial soil, but in calcareous soil, seed yield (1.14 g/plant) and seed number 414 seeds/plant were recorded in plants supplemented with M-CuO NPs as a protectant. In both soils, maximum plant height was increased by protective applications of M-CuO NPs at 200 ppm. Thus, the present study suggested that among foliar sprays of copper nanocompounds, protective activity shows better results as compared to curative activity. Among all the treatments, M-CuO NPs were found to be most effective in suppressing disease and improving productivity and growth-promoting effects of Brassica.

Abstract Structurally diverse fused polycyclic pyrrolo[3,2-c]quinolinone/pyrrolizino[2,3-c]quinolinone hybrids were synthesized to get excellent yields via a tandem multi-component reaction sequence employing an environmentally benign solid state melt reaction involving [3+2]-cycloaddition process followed by two consecutive annulation steps. Baylis–Hillman products, used as dipolarophiles, were synthesized from various substituted aryl/heteroaryl aldehydes in the presence of DABCO and methyl acrylate, while the 1,3-dipole component was derived in situ from indoline-2,3-dione and acyclic/cyclic amino acid viz N-methylgylcine/l-proline. The structure of the unusual tandem products was unambiguously assigned by spectroscopic and XRD analysis. The products arose through the formation of three new rings, five new bonds, and three adjoining stereocenters with complete diastereomeric control.

Abstract Thiosulfate gold leaching is a green gold extraction technology. Here, the effects of thiosulfate, copper ion, ethylenediamine, and polarization voltage on the dissolution of gold in this system were investigated by an electrochemical method. The results showed that the addition of thiosulfate promoted the dissolution of gold, but increasing the thiosulfate concentration had a little additional effect. The addition of ethylenediamine also increased the dissolution of gold, but the dissolution resistance of gold increased after adding ethylenediamine. The dissolution of gold increased, the diffusion resistance increased, and the dispersion effect increased upon increasing the copper ion concentration. The copper–ethylenediamine–thiosulfate system did not display passivation (or only weak passivation) upon increasing the polarization voltage, which indicates that the system was relatively stable. The influence of three factors on the dissolution of gold followed the order thiosulfate > copper ion > ethylenediamine.

Abstract The micron-scale diamond film was prepared using hydrogen and methane as the mixed gas supplies via self-developed 3 kW/2,450 MHz microwave plasma chemical vapor deposition (MPCVD) equipment. On this basis, the evolution of the surface morphology, hydrophobicity, and electrical properties of samples under different hydrogen plasma etching times was investigated. The results indicate that the crystal edge and the top of the diamond grain were preferentially etched when etching time is less than 30 min. The surface roughness reduced from 0.217 to 0.205 μm, and the resistance value decreases from 3.17 to 0.35 MΩ. However, as the etch time increases to 120 min, the etching depth increases, and the surface roughness was increased. Simultaneously, the contact angles increased from 62.8° to 95.9°, which indicates that the surface of the diamond films exhibits more pronounced hydrophobicity. The treatment time of hydrogen plasma has no significant effect on the resistance value in the range of 0.26–0.50 MΩ. The mechanism of surface etching by hydrogen plasma was also discussed.

Abstract The present study employed molted feather ash extract from Pavo cristatus to synthesize zinc oxide nanoparticles (Pcf-ZnONPs). The Pcf-ZnONPs were characterized through advanced spectroscopy techniques to study the chemical and physical properties of NPs. Pcf-ZnONPs specifically exhibit an absorption peak at 365 nm in the UV spectroscopy analysis. TEM and SEM confirmed the nanoscale presence of ZnO. The antibiofilm and antibacterial properties of Pcf-ZnONPs were assessed against Staphylococcus aureus and Pseudomonas aeruginosa . At a concentration of 25 µg·mL −1 , Pcf-ZnONPs exhibited a significant reduction in the thickness of bacterial biofilms. Breast cancer cell lines (MDA-MB-231) and fish cell lines were used to investigate in vitro anticancer activity. The MTT experiment demonstrated that Pcf-ZnONPs have good anticancer efficacy against a breast cancer and a fish cell line. The nontoxicity and biocompatibility of Pcf-ZnONPs were also investigated, exhibiting excellent hemocompatibility with red blood cells and no appreciable toxicity in Brine shrimp. In conclusion, Pcf-ZnONPs may be deemed nano-biomedicine compatible with biological systems for the treatment of bacterial illnesses in higher species.

Abstract The synthesis of cinnolines has found great interest due to their diverse biological and industrial potency. Yet, the reported synthetic protocols for their synthesis showed limitations that involve harsh reaction conditions such as strong acidic or basic medium, low reaction yields, and using expensive and high loading catalysts. The C–H functionalization has been recognized as intriguing synthetic approach for the synthesis of aromatic/heteroaromatic scaffolds over the past two decades. Here, we reported a novel metal-catalyzed free photocatalytic synthesis of polyfunctionally substituted cinnolines. When ethyl 1-aryl-5-cyano-4-methyl-6-oxo-1,6-dihydropyridazine-3-carboxylates and nitrostyrene derivatives are irradiated with white light (LED 30 W) in ethanol in the presence of piperidine (30 mol%) in open air for 8 h at room temperature, the corresponding polyfunctionally substituted cinnolines are obtained in excellent yields (90–95%) via C–H activation of pyridazine methyl group and nitrostyrene (–N═O) function. Several merits were achieved, which are as follows: (1) the reaction is metal-free; (2) the reaction proceeds with increasing energy efficiency; (3) diversity of functionally substituted cinnolines; (4) high EcoScale value, which reflects the greens of the reaction; and (5) ease handling either in conducting the reaction or in the isolation of products.

Abstract Throughout history, the utilization of plant products as medicinal remedies has been widespread, with numerous modern drugs finding their origins in the plant kingdom. Taxol, derived from Taxus species, stands out as an exceptional and highly potent anticancer medication. In this study, we present a rapid one-pot synthesis method for silver nanoparticles (AgNPs) using the leaves of Taxus wallichiana Zucca in the presence of sunlight. The synthesized AgNPs were comprehensively characterized using X-ray diffraction, transmission electron microscopy, and HPLC Q-TOF. The AgNPs were further investigated for their antioxidative, anticancer, anti-inflammatory, and antiurolithi properties. The anticancer activity was assessed through a sulforhodamine B assay conducted on the MDA-MB-231 human breast carcinoma cell line and SiHa human cervical cancer cell line. The findings of this study reveal the impressive antioxidative, anticancer, anti-inflammatory, and antiurolithi characteristics exhibited by AgNPs synthesized from leaf extracts. This research highlights an environmentally friendly and cost-effective approach to producing AgNPs by utilizing plant extracts as reducing agents, underscoring the immense potential of natural resources in advancing nanotechnology and its applications.

Abstract Everything around us is made up of atoms and molecules. The properties of quantum atoms are sought to understand the behavior of a particular object. But with the advent of research, it was discovered that there is a quantity smaller than the molecular size. The nanoscale measures a fraction of a billionth of a meter. The atom of an object measures 0.1 nm. Since atoms are the building blocks of matter, at the nanoscale one can combine these atoms to create new materials. The proposed model displays the properties of these nano-scale elements in modern medical applications. The nano-scale research of matter is fascinating because it is the basic phase in which atoms are held together. Therefore, by manipulating material at this level, one can create many different types of objects. This proposed model calculates the operation requirements and expects the results. Based on the operational requirements, the proposed model provides the suggestions. This will be helpful for the medical researchers to identify the proper medical treatments based on the microbiological requirements.

Abstract In this study, iron concentrate and blast furnace dust were used as raw materials, and graphite was used as a reducing agent for mixing and briquetting. The briquettes were roasted in a high-temperature tube furnace at different temperatures and held for a certain time to simulate the pre-reduction sintering process. The effects of dust content, reduction time, and reduction temperature on the removal rate of zinc, potassium, and sodium and the metallization rate of the pre-reduction sintered products were investigated. The reduced briquettes were characterized by X-ray diffraction, scanning electron microscopy-energy dispersive spectroscopy, and flame atomic absorption spectroscopy to further explore the mechanisms of zinc, potassium, and sodium removal. The Zn removal rate and metallization rate increased gradually with the increase in dust content, reaching 97.57% and 87.14% at 30% dust content, respectively. Both K and Na removal rates reached a maximum of 83.57% and 94.78%, respectively, at 25% dust content. With the increase in reduction time and temperature, the removal rate of the three elements and the metallization rate gradually increased. When the briquettes with 20% blast furnace (BF) dust content were reduced at 1,200℃ for 20 min, the removal rates of zinc, potassium, and sodium reached 95.66%, 79.97%, and 91.49%, respectively, and the metallization rate reached 84.77%. It shows that the pre-reduction sintering process can effectively remove Zn, K, and Na from the BF dust and meet the requirements of subsequent BF production. The research results can provide some theoretical basis for industrial production.

The briquettes were roasted in a high-temperature tube furnace at different temperatures and held for a certain time to simulate the pre-reduction sintering process. The effects of dust content, reduction time, and reduction temperature on the removal rate of zinc, potassium, and sodium and the metallization rate of the pre-reduction sintered products were investigated. The reduced briquettes were characterized by X-ray diffraction, scanning electron microscopy-energy dispersive spectroscopy, and flame atomic absorption spectroscopy to further explore the mechanisms of zinc, potassium, and sodium removal. The Zn removal rate and metallization rate increased gradually with the increase in dust content, reaching 97.57% and 87.14% at 30% dust content, respectively. Both K and Na removal rates reached a maximum of 83.57% and 94.78%, respectively, at 25% dust content. With the increase in reduction time and temperature, the removal rate of the three elements and the metallization rate gradually increased.
