These nanoparticles can be synthesised in the laboratory by using green synthetic methods. Hence, in the present study dark brown colour Ag-NPs have been synthesized from 0.01 mM AgNO3 using Azadirachta indica leaf extract as a reducing agent and characterised via different spectroscopic and microscopic techniques. The average particle sizes of the synthesized Ag-NPs are found to be 36 nm and all the particles are mostly spherical in shape. These biosynthesized Ag-NPs effectively have mitigated the mycelial growth of F. oxysporum and F. moniliforme. However, the inhibition has been found better for F. oxysporum as compared to F. moniliforme. At 500 ppm concentration of Ag-NPs, the reductions in mycelial growth have been found to be 100 and 80% for F. oxysporum and F. moniliforme, respectively. So, it can be concluded from the study that Ag-NPs prepared from A. indica leaf extracts could be explored for developing fungicidal formulations.","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135659785","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}

Nowadays researchers have been trying to investigate the antimicrobial properties of garlic and ginger peels extracts. Nevertheless, the effects of these materials on synthetic leather have not been experimented. The study aims at antimicrobial treatment of synthetic leather by the peels extracts and examining it against the staphylococcus epidermis bacterium. The peels have been collected in Bahir Dar city, Ethiopia, dried in the oven for one hour at 104°C, weighed and grounded in a grinder with a mesh size of 50-300 mesh. For both materials, 40 g of peel powder has been dissolved in 400 mL of ethanol solvent and stirred by a magnetic stirrer and then extracted by ultrasonic extraction method. Leather samples have been treated by extracted peels (5%, 15% and 20%) together with citric acid as a binder and soap as wetting agent. The antimicrobial properties of the treated samples have been assessed by a disc diffusion test method. The garlic peel extract at all concentrations levels has a wider inhibition zone indicating that garlic peel extract is more efficient at inhibiting Staphylococcus epidermis growth than ginger peel. Therefore; it could be used as antimicrobial treatment of synthetic leather.","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"1 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70702031","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 deposition of polymer coating has covered the surface cracks to a significant level and the fact has been confirmed by FE-SEM coupled with EDAX wherein the atomic percentage of Ti (99.90%) in non-coated surface has been decreased markedly to 0.42% after coating. Scratch resistance and adhesion power of bilayer coating has been increased as indicated by the higher critical loads Lc 1 (16.71 N), Lc 2 (17.56 N), Lc 3 (17.96 N) when a progressive load of 1 N to 20 N is applied over the coated surface. Further, Electrochemical impedance spectroscopy (EIS) and potentiodynamic-polarization studies have shown that the value of polarization resistance is inversely proportional to the corrosion rate. Thus decrease in the corrosion rate from 107.5×10 -2 (mm year -1 ) for the non-coated alloy to 2.88×10 -2 (mm year -1 ) for CH/EU coating demonstrated that coating enhanced the corrosion resistance of the alloy in the physiological condition. The in vitro antibacterial test conducted against S. aureus, B. subtilis, P. vulgaris and P. auregenosa has shown a significant inhibition zone of 9 mm, 6 mm, 7 mm and 10 mm, respectively, thus indicating the possible application of the polymeric coating material on the dental implants.","PeriodicalId":13388,"journal":{"name":"Indian Journal of Chemical Technology","volume":"1 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70701655","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}
