Beginning with an exploration of solar energy conversion principles, we underscore the pivotal role of DSSCs in harnessing renewable energy. The significance of high-performance counter electrodes is emphasized, necessitating materials with superior catalytic activity, conductivity, and stability. We provide an in-depth analysis of various counter electrode types, encompassing carbon-based, metal-based, and emerging nanostructured materials like carbon nanotubes.

The fibrillation treatment facilitated the separation of PCNFs bundles into a nanonetwork of extensively disordered, elongated, and pliable nanofibers, with a width of 5.2 ± 1.3 nm. Furthermore, the physicochemical, structural, rheological and thermal properties of the produced PCNFs were investigated through various analytical techniques, including conductometric titration, FTIR, <sup>13</sup>C/<sup>31</sup>P NMR, XPS, rheology, and TGA-MS. Second, crosslinked phosphorylated cellulose nanopaper (Cr-PCNP) was prepared using solvent casting, followed by a crosslinking reaction through a heat treatment stage. The Cr-PCNP revealed notable tensile strength (reaching up to 72.65 MPa) and Young's modulus (reaching up to 2.41 GPa), along with excellent flexibility. As revealed by the micro combustion calorimeter, the heat release rate (HRR) of Cr-PCNP significantly decreased by 61.76 %, compared to CMFs.

However, the current design practices are not remanufacturing-inclusive, i.e., the majority of products are designed for a single life cycle. As a result, potential products that can sustain multiple life cycles are deprived of additional benefits of being designed for remanufacturing, such as reduced material usage, lower cost, and improved environmental impact. Moreover, the uncertainty in design, material selection, and economics are not considered to produce remanufacturable designs. Accordingly, this research proposes a design for remanufacturing (DfRem) framework that accounts for design uncertainty and material price volatility. The framework systematically explores the design space, performs design optimization under uncertainty, followed by topology optimization to provide additional mass savings, and finally, a price volatility analysis for plausible design material choices. The candidate designs are evaluated based on their design mass, material price volatility, failure mode characteristics, carbon footprint, and embodied energy impacts. The proposed framework's utility is demonstrated via the use of an engine cylinder head case study subjected to thermo-mechanical loads along with fatigue and wear failure. Considering grey cast iron and aluminum alloy as the design material choices, it was found that the cast iron design reduced the initial design mass by 6% as opposed to a 5% decrease for aluminum. On the other hand, about 8% area of the cast iron design failed due to fatigue, compared to 3% for aluminum. We further observed that although the aluminum design provided better mechanical performance than the cast iron design, this material was more expensive and volatile in price.</div></div>","PeriodicalId":22097,"journal":{"name":"Sustainable Materials and Technologies","volume":"42 ","pages":"Article e01163"},"PeriodicalIF":8.6,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142655994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
