Polymer membranes used for biomedical applications, such as in hemodialysis and blood oxygenators, must also have good antithrombogenic and biocompatibility characteristics. Recently developed polyetherimide/polyvinylpyrrolidone (PEI/PVP) hollow fiber membranes showed good potential as an alternative to clinically available membranes, as evaluated by the transport properties of blood-targeted molecules relevant in the treatment of patients with renal chronic diseases. Aiming at improving the hemocompatibility of these membranes, the incorporation of heparin onto their surface was sought as a promising attempt to achieve this goal. In this work, flat sheet PEI/ PVP membranes were prepared by the phase inversion technique and were functionalized through the covalent grafting of heparin. Characterization included the follow-up of hydrophilicity, protein adsorption, prothrombin time (PT), activated partial thromboplastin time (aPTT), hemolysis occurrence, platelet adhesion, and complement system activation. The results showed that heparinization resulted in more hydrophilic membranes (contact angle reduced from 76.5° to 58.5°) and in the reduction of protein adsorption by more than 50%. In contact with human blood, these membranes reduced the occurrence of platelet adhesion, increased aPTT from 34 to 46 s, and did not lead to complement system activation. Such PEI/PVP membranes have therefore remarkable antithrombogenic and biocompatibility characteristics, which are highly desired for use in biomedical applications such as hemodialysis filters.</p>","PeriodicalId":9194,"journal":{"name":"Brazilian Journal of Chemical Engineering","volume":"5 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138568872","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 study explores the potential of anaerobic co-digestion (AcoD) as a sustainable solution, specifically investigating its capacity for biogas generation from these agricultural residues. The primary objective is to determine the optimal substrate mixing ratios (SMRs) to maximize biogas yield. In-depth examination revealed that the highest biogas production reached a significant 2880 mL with a blend of 60% RH and 40% PP (RH60PP40). Additionally, the 80% RH and 20% PP composite (RH80PP20) demonstrated a substantial yield of 1996 mL. However, when plantain peels were used as the major substrate, biogas outputs decreased to 1250 mL and 173 mL for RH40PP60 and RH20PP80, respectively. Synergistic indexes (SI), measuring compatibility, reported values of 1.36 and 1.96 for the most promising samples, underscoring their optimal blending for biogas enhancement. From the perspective of digestate quality, plantain peel-based digestate (PP100D) stood out as a leading biofertilizer candidate due to its enriched nutrient profile. For the kinetic analysis, the logistic model was identified as the most predictive, outperforming the exponential and modified Gompertz models in mapping biogas production dynamics. Conclusively, the study accentuates that strategically optimized anaerobic co-digestion (AcoD) of RH and PP not only amplifies biogas outputs but also presents a viable, sustainable avenue for managing the environmental concerns associated with unchecked agricultural residue accumulation.</p>","PeriodicalId":9194,"journal":{"name":"Brazilian Journal of Chemical Engineering","volume":"58 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138513539","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 reactions were carried out with acetic acid and acetic anhydride using sulfuric acid, pyridine and triethylamine as catalysts. The acetylation reactions yielded a mixture of mono, di and triacetin respectively with short irradiation time and high selectivity to triacetin. Pyridine exhibits 100% of selectivity to triacetin in 30 min of microwave heating with 0.88% (<i>w</i>/<i>w</i><sub>T</sub>) of catalyst concentration. Microwave-heating technology has been demonstrated as an alternative to reach a green chemistry and to this end becomes essential the knowledge of the dielectric properties of the materials involved in microwave heating in order to operate under optimal conditions. Dielectric properties of the pure reagents and during the glycerol acetylation under conventional heating were measured. High loss tangent were obtained for reactions mixtures employing H<sub>2</sub>SO<sub>4</sub> and triethylamine and dielectric heating is dominated by ionic conductivity whereas with pyridine the dielectric heating of the reaction mixture is governed by dielectric relaxation process. Physical–chemical analysis of blended biodiesel with triacetin show values for viscosity, flash point, water content, density and acid number in accordance with current international standards. Gaseous emissions analyses of blended biodiesel showed significant reduction of CO emission (50%), CO<sub>2</sub> (25%) and 30% reduction in unburned hydrocarbon (UBHC) and 50% of NOx emissions.

Enhanced oil recovery (EOR) methods are applied to modify fluid–fluid and fluid–rock interactions in the reservoir, facilitating the oil displacement and, consequently, increasing the recovery factor. In this work, the use of silica nanofluids as EOR method to reduce the IFT and to change the wettability conditions of reservoir rock were evaluated. For experimental tests, crude oil from a reservoir in a Brazilian Pre-salt field was used as oleic phase. No significant change in IFT was observed with an increase in the concentration of SiNPs for both distilled water and low salinity water (1000 ppm) dispersant fluids. The significant reduction of the contact angle is observed for nanofluids with 0.02 wt% SiNP. Finally, the Amott test was performed in a carbonate rock sample to reaffirm the action of these chemicals in oil recovery, corroborating the potential of nanofluids to EOR applications.
