To mitigate this issue, we focus on the synthesis of biodegradable surfactants capable of emulsifying free water to form stable emulsions. Among various classes of biodegradable surfactants tested, oleic acid diethanolamide emerged as a promising candidate due to its superior emulsifying properties and relatively unexplored potential. To assess the maximum water emulsification, oleic acid diethanolamide was synthesised by optimising the ratio of oleic acid to diethanolamine. Out of the prepared formulations, a clear emulsion was achieved at a 1:1 ratio of oleic acid to diethanolamine, demonstrating higher efficacy in water emulsification compared to other formulations. Characterization analyses, including FTIR and total acid number, were conducted for all surfactants. Formulations utilising the synthesised surfactant at varying concentrations, ranging from 1 to 10% were used to stabilise 5% water in the emulsions. The study demonstrated that clear emulsions showed extended stability beyond 45 days with formulations having surfactant concentrations ranging from 6 to 10%. The emulsions were further characterized for key fuel properties such as calorific value, viscosity and cloud point to meet the operational requirements of the fuel. The research aims to provide a sustainable, environment friendly and operationally efficient solution to the persistent problem of water precipitation in large diesel storage tanks, offering operational efficiency and environmental benefits to the fuel industry.</p></div>","PeriodicalId":502,"journal":{"name":"Bulletin of Materials Science","volume":"48 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12034-024-03383-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143446588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considering the admixture’s limitation in recent years, the employment of waste materials in stabilizing such soils is highly encouraged. This study investigates the efficacy of digestate ash as a soil stabilizer under diverse temperature conditions (100°C to 800°C) through an unconfined compressive strength test at an optimal stabilizer content. The Atterberg’s limits and compressive strength test were performed on the clay with and without additives at room temperature through various curing times (0 and 28 days). The digestate ash was used at 0 to 25% (by dry clay weight) as an additive along with the initial consumption of lime as an activator at 4.5% (by dry soil weight). The maximum unconfined compressive strength value of 336 kPa was observed when using 15% digestate ash obtained at 560°C for a curing period of 28-days. The significant alteration in mineralogical and chemical composition was identified when the DA-modified clay underwent X-ray diffraction and fourier transform infrared examinations. This research facilitates better understanding of digestate ash-based soil stabilization in different thermal conditions, aiding sustainable soil improvement in civil engineering and environmental remediation.</p></div>","PeriodicalId":502,"journal":{"name":"Bulletin of Materials Science","volume":"48 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12034-024-03394-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143446587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, silk fibroin (SF) nanofibre mats coated with polypyrrole (PPy) were prepared through electrospinning and chemical polymerization. Scanning electron microscopy (SEM) showed even and firm coating of PPy around the nanofibres, and fourier transform infrared spectroscopy (FTIR) analyses of the conductive mats confirmed the presence of hydrogen bonds or electrostatic interactions between PPy and SF. The conductivity of the composite mats could be regulated by varying the pyrrole monomer concentration from 10–20 mM, resulting in corresponding changes in conductivity from 9.4 ± 3.4 × 10<sup>–5</sup> to 4.6 ± 1.0 × 10<sup>–3</sup> S cm<sup>–1</sup>. The mechanical strength, hydrophilicity and biodegradability of the mats exhibited similar changing trends. Biodegradability tests showed weight losses of 51.2, 13.6, 11.2 and 15.1% for composite mats with varying PPy coating rates on the 28th day, revealing that the biodegradability can be regulated and optimised by varying the pyrrole concentration. Schwann cell culture confirmed that the SF/PPy mats improved cell proliferation and adhesion compared to pure SF mats.
