To investigate this aspect, the biofilm formation ability of E. coli on both LP and untreated surfaces of 630 stainless steel was examined over 48 h. Biofilm on the coupons was analyzed for bacterial enumeration and total carbohydrates concentration, and also was observed using scanning electron microscopy. The surface modification by texturing caused a 6 h delay in the attachment of E. coli, and an approximately 99% decrease in the number of adhered bacteria was determined at the end. However, it was determined that E. coli produced more extracellular polymeric substances (EPS) (p<0.01) to attach to the LP surface and formed a multi-layered biofilm. In conclusion, LP surface can be recommended regarding the bacterial count and the delay in attachment, but the increased amount of EPS limits its use.","PeriodicalId":14807,"journal":{"name":"Johnson Matthey Technology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67351266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cobalt chrome (Co-Cr) was a viable alternative to stainless steel for long-term applications with superior ductility. Their mechanical properties are explained with high-strength biomaterials for elastic models of 220 to 2300 GPa, more significant than the 30 GPa of bones. The goal of combining metals and bioactive glass has resulted in high biocompatibility and improved bioactivity of the implant’s surface. In addition, it triggers new bone tissue to regenerate throughout osteogenesis and mineralization. However, implantation failure still occurs and requires surgery revision due to a lack of adequate bone bonding and delamination at the coat’s surface layer of the implant. The current review summarizes the coating's adhesion between bioactive glass and Co-Cr substrate applied through Electrophoretic deposition (EPD).","PeriodicalId":14807,"journal":{"name":"Johnson Matthey Technology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67351428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Life Cycle Analysis (LCA) offers the gold standard for process assessment, but LCA can take weeks or months to complete, with incomplete databases and inflexibility in comparing different chemical pathways.In this study, we demonstrate an alternative and complementary methodology. By simplifying the metrics used to describe chemical processes, each process may be linked to another by its feedstocks and products. This generates a network of the chemical industry, which may be investigated using graph theory principles. A case study of the plastics industry is provided, using publicly available information to quantitively compare with a more formalised and detailed LCA approach.This methodology proves useful for quickly estimating the carbon intensity and water footprint of thousands of routes. Further development, such as including Scope 3 emissions and additional industrial data, may further improve the methodology.","PeriodicalId":14807,"journal":{"name":"Johnson Matthey Technology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67350921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, lichen species including Usnea sp., Platismatia glauca, Ramalina farinacea, Evernia divaricata, Bryoria capillaris, Hypogymnia tubulosa, Pseudevernia furfuracea and Lobaria pulmonaria were examined for their antibacterial efficacies against Staphylococcus saprophyticus subsp. saprophyticus (TR5) and Salinicoccus roseus (KV3) which are proteolytic and lipolytic Gram-positive moderately halophilic bacteria. The extracts of P. glauca, B. capillaris, P. furfuracea, and L. pulmonaria had no antibacterial efficiency against test bacteria. On the other hand, the extracts of H. tubulosa, R. farinacea, Usnea sp., and E. divaricata had considerable antibacterial effect with varying percentages of inhibition. The maximum inhibition ratios at the tested concentrations of 240-15 µg/ml for lichen samples of H. tubulosa, R. farinacea, Usnea sp, and E. divaricata were detected as 94.72±0.75%, 76.10±1.85%, 99.36±0.04%, 89.49±2.26% for TR5 and 97.44±0.14%, 95.92±0.29%, 97.97±0.39%, 97.58±0.53% for KV3, respectively. The most remarkable suppression was obtained with Usnea sp. extracts against KV3. These results indicate the need for further studies investigating the applicability of these natural resources to control moderately halophilic bacteria in the preservation of raw hides/skins.","PeriodicalId":14807,"journal":{"name":"Johnson Matthey Technology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67351126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is a known fact that fluorocarbon compounds, which are widely used for this purpose, are quite harmful to the environment. Therefore, within the scope of this study, a water repellent chemical that does not contain fluorocarbon compounds was treated to 100% cotton fabrics and compared with fluorocarbon compounds. As a result of the analyzes, it has been seen that the environmentally friendly chemical is at least as effective as the fluorocarbon compounds. According to the spray test, a water repellency at ISO 5 level was obtained. In addition, the fabrics' high water vapor permeability, air permeability and low bending stiffness (280 mg.cm) were given effective results in terms of usage properties. This has yielded very important results in terms of sustainability and eliminating the use of fluorocarbons in ecological terms.","PeriodicalId":14807,"journal":{"name":"Johnson Matthey Technology Review","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67351411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
