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.","PeriodicalId":12758,"journal":{"name":"Green Processing and Synthesis","volume":null,"pages":null},"PeriodicalIF":4.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43317212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":12758,"journal":{"name":"Green Processing and Synthesis","volume":null,"pages":null},"PeriodicalIF":4.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47332992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.","PeriodicalId":12758,"journal":{"name":"Green Processing and Synthesis","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135448211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.
