For ‘smart’ or knowledge-based design of photocatalysts, it is, however, important to understand the adsorption and degradation dynamics and their relationship with the particulate surface. Hansen solubility parameters (HSPs) can provide relevant information about the particle surface characteristics in dispersions. Herein, HSPs of six different titania materials including their composites with graphene are determined and they are related to the adsorption capacities of Bisphenol A and chloroform. The effect of the underlying synthesis procedures and graphene addition on the pollutant adsorption in the liquid phase is examined. The results show that the Hansen sphere radii correlate with the specific equilibrium adsorption capacities of the titania-based substrates for both pollutants. The type of crystallographic structure and the addition of graphene increase the adsorption dynamics and are accurately correlated with the HSP sphere radii. HSPs can thus serve as a characterization method for understanding liquid pollutant adsorption or, set in a wider context, the interaction of ligands or surface groups with a specific particle surface.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 5","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsu.202400795","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144171308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fiber yield increased from ≈0.84% to 11.26%, the crystallinity index (CI) increased from ≈55.6% to 67.3%, and linear density decreased from ≈73.6 to 51.7 Tex with the increase in retting time, temperature, and water flow rate. However, the overall trends are complicated due to the heterogeneity in the structures and properties of the starting plant materials.

Contrastingly, the lack of proper management leads to a large accumulation of plastic waste, majorly including polyolefins and polyesters. Conventional management methods possess significant drawbacks like cost-ineffectiveness and greenhouse gas emissions. Over the last decade, chemical processes have shown promising potential for plastic management but only hold a 0.1% share in plastic recycling. The catalytic processes offer excellent protocols to obtain high-value liquid fuels, waxes, and chemicals from plastic waste. This review presents an elaborate discussion on the state of the art in the reductive upcycling of polyolefins, polyesters, and mixed plastic waste. The review initially discusses the alarming statistics of plastics and conventional approaches followed by an introduction to chemical processes. Further, various recently reported catalytic upcycling strategies have been elaborated in detail followed by catalyst deactivation, technoeconomic analysis, and life cycle assessment to obtain a deeper understanding of the current state of this research field. Finally, a detailed summary of the current state of plastic management along with the existing challenges and countermeasures is discussed to open new avenues in plastic waste management research.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 4","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study combines attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy with partial least squares (PLS) regression to predict deterioration induced by accelerated weathering (xenon lamp method) in waterborne acrylic coatings varying concentrations of cellulose nanofiber (CNF), an additive known to suppress surface defects and discoloration. Mid-infrared spectral data (400–4000 cm−1) are used as explanatory variables, while weathering duration served as the response variable. Genetic algorithm-based wavenumber selection with PLS (GAWNSPLS) identified critical spectral regions contributing to model accuracy. The models demonstrated strong predictive performance, achieving coefficient of determination (R2) values of 0.95 and 0.92 for coatings with 3.8% and 24.9% CNF, respectively, in leave-one-out cross-validation. Combining data across formulations achieved an R2 of 0.73, showcasing the method's robustness. Subtle molecular changes, such as carbonyl oxidation and structural rearrangements, are successfully detected. This framework offers a practical tool for evaluating coating deterioration, reducing reliance on labor-intensive inspections, and preventing timber decay. Additionally, the approach can accelerate formulation optimization by improving the efficiency of accelerated weathering tests.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 5","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144171247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally made from petroleum-derived polymers, these materials typically demand high energy for production, generate considerable dust during mixing components, have poor fire resistance, and degrade slowly. To address these issues, this work proposes a sustainable alternative using microfibrillated cellulose (MFC) and carbon black (CB) to create conductive cryogels by the freeze-drying method. The dispersibility of CB in aqueous suspensions of cationic or anionic MFC is studied, and the interactions between components are evaluated using advanced techniques, showing stronger interactions between CB and cationic cellulose. Also, the effect of CB content is assessed on the cryogels’ morphological, mechanical, and electrical properties. Results show cryogels with low densities (<55 mg cm−3), high porosities (>91%), strong network structures with high specific compression moduli (11–21 MPa cm3 g−1), and superior fire resistance. Electrical properties vary with CB content: 1–5 wt% CB results in static-dissipative behavior (≈108 Ω cm), while ≥10 wt% CB forms a conductive network (103–101 Ω cm). Overall, cationic MFC/CB cryogels exhibit promising properties, suggesting the potential for replacing plastic-based antistatic foams in electrical applications as a greener alternative.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 5","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144171190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electrochemical seawater splitting is a sustainable approach for hydrogen production and carbon dioxide (CO2) sequestration, producing hydrogen gas at the cathode and oxygen or chlorine gas at the anode. Simultaneously, minerals such as calcium carbonate and magnesium hydroxide precipitate at the cathode, especially when coupled with CO2 injections for the sake of CO2 sequestration. These precipitates are often dismissed as energy-intensive byproducts. However, they have untapped potential as resources for construction, manufacturing, and environmental remediation. Here, a comprehensive experimental investigation is presented into the electrochemical precipitation of minerals in seawater under varying operational conditions. By systematically varying applied voltage, current density, and CO2 flow rate, the conditions that optimize mineral yield and selectivity while minimizing energy consumption are revealed. The findings advance the understanding of electrochemical synthesis and material processing in aqueous solutions, with a particular focus on the mineralization of calcareous compounds and their transformation into large-scale aggregates. These findings also support an additional and highly scalable application of seawater electrolysis, encompassing not only oceanic renewable hydrogen production and CO2 sequestration but also the sustainable production of carbon-trapping minerals and aggregates.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 3","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsu.202400943","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The physico-chemical and structural properties of these carbocatalysts are correlated with their catalytic activities. The PNC catalyst pyrolized at 1200 °C for 4 h using K2CO3 (PNC1200-4K2CO3) provides a complete pollutant degradation after 150 min, while PNC catalyst pyrolized at 1200 °C for 4 h without activation requires 300 min. PNC1200-4K2CO3 performance compares favorably with previous reports. The superior catalytic activity of this reusable catalyst is attributed to its highest population of π-extended aromatic domains as active sites together with high porosity. The catalytic formation of 1O2, HO. and HOO. radicals are supported by electron paramagnetic resonance measurements and selective quenching experiments.
