However, maintaining a high biomass of oil-degrading bacteria has been proven challenging. Here, a carrier that enables simultaneous bacterial immobilization and oil absorption is proposed as a solution. Porous cellulose triacetate beads (PCTBs) derived from cellulose triacetate powder was obtained through the acetylation of kapok fibres. This study revealed that PCTBs with both 12.5% and 16.67% w/v precipitated in distilled water showed greater crude oil absorbency of 2.4850 ± 0.1326 g/g and 1.9852 ± 0.2343 g/g, respectively. Reusability tests of PCTBs showed promising results with no reduction in oil absorption after five reabsorption cycles. Successful immobilization of the oil-degrading bacteria, Acinetobacter venetianus on PCTBs was achieved and enumeration of bacteria showed no statistically significant differences compared to those on kapok fibres despite the raw fibres having a larger surface area. The SEM analysis revealed that A. venetianus adhered to the outer and inner walls of the beads through secreted exopolysaccharides. PCTBs with oil-degrading bacteria are potentially able to simultaneously absorb and degrade oil, thus highlighting the novelty of a working alternative to sustainable oil spill mitigation.","PeriodicalId":12929,"journal":{"name":"Green Materials","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44721530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High-performance and environment-friendly lubricants for water-based drilling fluid are urgently needed. In this work, Chinese yam (Dioscorea opposutifolia L.) was investigated as a drilling fluid lubricant, the effects of Chinese yam slurry on drilling fluid lubricating properties at different temperatures were investigated, and the compatibility and inhibitory properties of Chinese yam slurry were studied. The results show that the viscosity coefficient of the mud cake is reduced by 44.5% as 1.5% Chinese yam slurryadded in water-based drilling fluids. Chinese yam also has certain temperature resistance in drilling fluids, and it can inhibit the swelling of clay. Chinese yam slurry is compatitive compatible with other drilling fluid additives, and the lubricity of modified drilling fluids can also be improved effectively. The lubrication mechanism of Chinese yam slurry was discussed through TGA, SEM, FTIR, and contact angle tests.","PeriodicalId":12929,"journal":{"name":"Green Materials","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2022-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41830868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The storage modulus, loss modulus and tan δ values of the hybrid composites were also determined to evaluate the DMTA performance. The results showed that the storage modulus of jute/polyester resin is superior to those of the jute–wood/polyester hybrid and wood/polyester up to the glass transition temperature (T g). However, for temperature ranges higher than T g, the stiffness of hybrid composites increased relatively. The T g values from loss modulus and tan δ peaks support this effect of hybridization. Tests on mechanical properties showed that the jute/polyester specimens had a significant increase in tensile strength compared with the jute–wood/polyester hybrid and wood/polyester specimens. The results of tests of physical properties showed that the wood/polyester specimen had the lowest values of thickness swelling, water absorption and moisture content compared with the jute/polyester and jute–wood/polyester composites. The highest contact angle was obtained from composites made of wood/polyester. It could be concluded that the composites with enhanced performance could be used as novel green composites in various sectors.","PeriodicalId":12929,"journal":{"name":"Green Materials","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2021-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138514980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Waste eggshell (ES) generated from the food industry has been used as primary reinforcement material. Waste grinding sludge (GS) produced from the iron forging sector was utilized as secondary reinforcement content. Cr content has been further encapsulated to the composite material to prevent the composite material's grain growth. The composite material was developed by the stir casting process. Experimental results concluded that tensile strength, compressive strength, and hardness of base material (AA5052 alloy) had been improved by about 18.02 %, 23.40 %, and 49.53 respectively, by adding 4.5 % of ES, 4.5 % of GS, and 1.5 % of Cr. Microstructural analysis of the AA5052/4.5 % ES/4.5 % GS/1.5 % Cr composite shows the fair distribution of reinforcement content. XRD of the Al/4.5 % ES/4.5 % GS/1.5 % Cr composite shows the occurrence of Al, Fe2O3, CaCO3, CaO, and Cr phases. Corrosion weight loss and thermal expansion behavior of developed composite have also been explored to observe the ES, GS, and Cr addition in the aluminum alloy.","PeriodicalId":12929,"journal":{"name":"Green Materials","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2021-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47852458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
