Abstract

This research introduces a sustainable method for extracting carboxymethyl cellulose (CMC) from durian peel waste via supercritical carbon dioxide (Sc.CO₂) processing, leading to the development of advanced aerogel scaffolds. The study evaluates the influence of Sc.CO₂ treatment times (60, 90, and 120 min) on the properties of the produced CMC, investigating enhancements in terms of thermal stability, crystallinity, and mechanical attributes through thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and mechanical strength assessments. It was discovered that a 90-minute treatment duration yielded CMC aerogels with notable improvements in porosity, structural robustness, and mechanical resilience. This innovative approach not only proposes a viable strategy for repurposing agricultural by-products but also significantly augments the functional qualities of CMC aerogels, rendering them highly applicable in diverse fields. The outcomes underscore the efficiency of Sc.CO₂ treatment in refining the mechanical and thermal characteristics of CMC derived from durian peel waste, facilitating the creation of aerogel scaffolds poised for use in various sectors including drug delivery, water purification, and eco-friendly packaging, thereby contributing to the global initiatives for sustainability and efficient waste management.

从榴莲皮废弃物中分离羧甲基纤维素并制备气凝胶支架的生态友好型方法

本研究介绍了一种通过超临界二氧化碳（Sc.CO2）处理从榴莲皮废弃物中提取羧甲基纤维素（CMC）的可持续方法，从而开发出先进的气凝胶支架。该研究评估了 Sc.CO2 处理时间（60、90 和 120 分钟）对所生产的 CMC 性能的影响，通过热重分析（TGA）、差示扫描量热仪（DSC）和机械强度评估，研究了热稳定性、结晶度和机械属性方面的改进。研究发现，90 分钟的处理时间可产生 CMC 气凝胶，其孔隙率、结构坚固性和机械韧性都有明显改善。这种创新方法不仅为农业副产品的再利用提出了一种可行的策略，而且还大大提高了 CMC 气凝胶的功能品质，使其在不同领域都有很高的应用价值。研究结果表明，Sc.CO2 处理能有效改善从榴莲皮废弃物中提取的 CMC 的机械和热特性，促进气凝胶支架的创造，使其可用于药物输送、水净化和生态友好型包装等多个领域，从而为可持续发展和有效废物管理的全球倡议做出贡献。

期刊介绍： Nano-Structures & Nano-Objects is a new journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. The journal is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. The journal is focused on the objects rather than on their applications. However, the research for new applications of original nano-structures & nano-objects in various fields such as nano-electronics, energy conversion, catalysis, drug delivery and nano-medicine is also welcome. The scope of Nano-Structures & Nano-Objects involves: -Metal and alloy nanoparticles with complex nanostructures such as shape control, core-shell and dumbells -Oxide nanoparticles and nanostructures, with complex oxide/metal, oxide/surface and oxide /organic interfaces -Inorganic semi-conducting nanoparticles (quantum dots) with an emphasis on new phases, structures, shapes and complexity -Nanostructures involving molecular inorganic species such as nanoparticles of coordination compounds, molecular magnets, spin transition nanoparticles etc. or organic nano-objects, in particular for molecular electronics -Nanostructured materials such as nano-MOFs and nano-zeolites -Hetero-junctions between molecules and nano-objects, between different nano-objects & nanostructures or between nano-objects & nanostructures and surfaces -Methods of characterization specific of the nano size or adapted for the nano size such as X-ray and neutron scattering, light scattering, NMR, Raman, Plasmonics, near field microscopies, various TEM and SEM techniques, magnetic studies, etc .
