However, it faces pressing issues regarding carbon emissions and resource management. Traditional open-loop systems generate substantial waste and pollution, exacerbating environmental concerns. Various emerging technologies offer promising solutions. Carbon Capture, Utilization, and Storage (CCUS) presents avenues for tackling carbon emissions. Utilization transforms CO2 emissions into valuable products, while Storage securely stores emissions to prevent atmospheric release. Closed-loop processes and waste valorization capitalize on material reuse, conserving natural resources, and minimizing waste. By promoting resource efficiency and waste minimization, circular economy principles align seamlessly with CCUS, closed-loop systems, and waste valorization. This study delves into utilizing Utilization technologies tailored to sugarcane 1G+2G bioethanol production, evaluates CO2 capture options, and presents applications. Storage strategies suitable for bioethanol production facilities are scrutinized, and deployment options are explored, highlighting the closed-loop system and waste valorization's role in waste reduction and environmental preservation. Through synergistic integration, these technologies pave the way for sustainable sugarcane bioethanol production, addressing economic and technological challenges while fostering innovation and collaboration. This comprehensive study will serve as a guide for transitioning to a circular economy model in bioethanol production.","PeriodicalId":8097,"journal":{"name":"Applied Science and Engineering Progress","volume":"114 25","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141667876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yield losses due to this pathogen are still not measured, but the damage could extend from the purple immature to the dried postharvest nuts. Therefore, there is a pressing need for safe, effective, and environmentally friendly control measures. This study reports on the successful formulation of various Ionic Liquid-loaded Eucalyptus Essential Oil Nanoemulsions (IL-EEONE) for potential applications against Stenotrophomonas maltophilia, a pathogenic bacterium responsible for kernel rot disease in Pili nut (Canarium ovatum). Combining eucalyptus essential oil (EO) and Tween 80 in an oil-in-water (O/W) system, followed by stirring and sonication, and the subsequent loading of 1-Butyl-3-methylimidazolium hydrogen sulfate ([Bmim][HSO4]), an ionic liquid, at varying ratios (1:1, 2:1, and 3:1), yielding the formation of IL-EEONE. The nanoemulsion droplets exhibited a size range of 9.4–12.26 nm, highlighting their nanoscale dimensions. The IL-loaded nanoemulsions formulated at varying ratios typically displayed nearly monodisperse characteristics, except for the higher concentration 1:1 ratio of IL:EEONE formulation, as indicated by their Polydispersity Index (PDI) values. Fourier Transform Infrared (FT-IR) analysis further confirmed the successful formulation of the different IL-EEONE nanoemulsion compositions. Significantly, these nanoemulsions demonstrated excellent inhibitory properties against S. maltophilia, as indicated by Zone of Inhibition (ZOI) ranging from 11.3 ± 0.58 mm to 32.7 ± 0.58 mm. The antibacterial activity varied from partially active to very active across different formulations, with the 1:1 IL-EEONE ratio formulation standing out as exceptionally effective. This study shows the potential of IL-loaded nanoemulsions, IL-EEONE, as a potential agent for mitigating S. maltophilia causing the kernel rot disease, offering innovative avenues for addressing bacterial infection in agricultural settings.","PeriodicalId":8097,"journal":{"name":"Applied Science and Engineering Progress","volume":" 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141676340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chitosan derived from black soldier fly (Hermetia illucens) maggot presents a biodegradable substitute. This study fabricated chitosan-based polymer electrolyte membranes by blending chitosan with polyvinyl alcohol (PVA) and polyacrylonitrile (PAN), then doping with ammonium chloride (NH4Cl) using the solvent-casting method. Varying NH4Cl compositions aimed to maximize ionic conductivity. Chitosan (13.455% water, 27.810% ash) was subsequently combined with PVA/PAN (20:80 w/w), NH4Cl, and casted onto petri dishes. Electrolyte membranes exhibited a maximum conductivity of 0.19612 ± 0.01572 S/cm with 0.9 g NH4Cl. FTIR spectroscopy verified the incorporation of chitosan (peaks at 3446.79 cm–1, 1643.35 cm–1, and 1151.50 cm–1), PVA (3446.79 cm–1 and 1136.07 cm–1), and NH4Cl (3371.57 cm–1 and 721.38 cm–1). SEM imaging visualized the incorporation of NH4Cl within the membrane. The chitosan-based biodegradable approach is compelling but limited by 0.19612 S/cm ionic conductivity, necessitating further compositional and processing optimizations for viable applications. Though it is promising for sustainable bio-sourced energy storage, challenges remain in enhancing conductivity through advanced polymer blends/dopants and scaling up for commercial biobattery manufacturing.","PeriodicalId":8097,"journal":{"name":"Applied Science and Engineering Progress","volume":" 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141678464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Various horseradish peroxidase (HRP) immobilization techniques— physical adsorption, covalent bonding, and cross-linking with glutaraldehyde—were applied to a regenerated cellulose (RC) membrane with a surface area of 44 m2 and a molecular weight cut-off of 30 kDa. The investigation examined factors influencing phenol removal, including phenol concentration, membrane fouling, and the reusability of immobilized enzymes. Results indicated that covalent bonding was the most suitable enzyme immobilization technique, achieving a remarkable 90.1% immobilization yield. Phenol removal efficiency reached 100% at 30 min under specific conditions: phenol concentration of 1 mg/L, pH 6.0, hydrogen peroxide concentration of 0.5 mM, and operating pressure set at 3 psig, with temperature maintained at 28 ± 3 °C. Membrane fouling resulted in a decrease in flux. The performance of fouling models was found to be influenced by phenol concentration, with the Cake Formation Model (CFM) proving most effective at low concentrations, while the Complete Pore Blocking Model (CBM) emerged as more suitable at higher concentrations. The immobilized enzyme exhibited reusability for five cycles, maintaining a phenol removal efficiency exceeding 50%. These findings contribute to understanding the enzymatic phenol removal process and the use of appropriate enzyme immobilization techniques for the effective and sustainable treatment of phenol-contaminated water.","PeriodicalId":8097,"journal":{"name":"Applied Science and Engineering Progress","volume":"5 19","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141684323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Historically, machinery has been employed to categorize the lime quality, with dual objectives of cost reduction and error mitigation, thereby facilitating the classifying process. Nevertheless, deploying such machinery to classify limes in their fresh produce form, intended for consumer sale, has encountered limitations imposed by the stringent criteria stipulated in Thai Agricultural Standards No. TAS 27-2017, a standard derived from the Codex Standard and widely adopted by numerous countries. Considering these constraints, the presented research aims to enhance the efficiency of limes classification, adhering to the standards. The Machine Learning System is designed to recognize and categorize limes based upon their skin color and defects to achieve this goal. This system employed convolutional neural network (CNN) models in conjunction with logistic regression equations, which are unavailable in the literature. The research findings indicate that this system is proficient in accurately presenting lime images and their corresponding quality classes via a Graphical User Interface on a computer screen, achieving an accuracy rate exceeding 90%. The implications of this research extend to the agricultural sector by augmenting the efficacy of Machine Learning for classifying limes in compliance with Thai Agricultural Standard No. TAS 27-2017.

In this study, enzymatic extraction of FuCS from two species of sea cucumber, Holothuria scabra and Bohadschia argus was undertaken using two protease enzymes, alcalase and papain. Response surface methodology (RSM) was employed in determining the optimal extraction conditions with the highest yield of FuCS concentration. The predicted optimal papain-assisted extraction conditions of Holothuria scabra and Bohadschia argus obtained a predicted FuCS yield of 1609.73 mg/100 g and 444.51 mg/100 g, respectively. To compare extraction efficiencies of two protease enzymes, employment of the RSM optimal conditions to Holothuria scabra resulted in 1538.76 ± 20.26 mg/ 100 g and 1295.50 ± 14.28 mg/100 g of purified FuCS for papain and alcalase, respectively.

The acquired FTIR and NMR spectrums of extracted FuCS showed typical bands of sulfation patterns and were compared to commercial FuCS. The extracted FuCS showed enzyme type dependent antioxidant activity, and significant tyrosinase inhibitory activity than commercial FuCS.
