However, current sizing agents, primarily reliant on non-covalent interfacial interactions, encounter significant challenges, including insufficient mechanical properties, substantial desizing effluent production, and non-biodegradability. Herein, a green, smart, redox-responsive keratin-based sizing agent was developed, inspired by the natural dynamic covalent behavior of disulfide bonds. This sizing agent demonstrates 47% greater adhesion to cotton fibers and 550% higher film fracture energy by enhancing covalent disulfide switches at the size–yarn interface and within the sizing films while reducing random coil conformations. Its reductive responsiveness facilitates easy removal, achieving up to 99.9% desizing efficiency at a bath ratio of 1 : 10 under ambient temperature conditions. The sulfhydryl-enrichment modification of feather keratins promotes reversible protein conformational changes and controllable covalent bonding during the sizing and desizing processes. Life cycle analysis (LCA) indicates a 73.69% reduction in CO<sub>2</sub> emissions compared with conventional petroleum-based polyvinyl alcohol (PVA) sizes, along with additional energy and water savings, attributable to the simplified desizing process and mild operating conditions associated with the keratin-based agents.</div></div>","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":"27 19","pages":"Pages 5624-5634"},"PeriodicalIF":9.3,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this case, increasing the PU biogenic carbon content is a strategy followed to enhance its sustainability, <em>e.g.</em>, by employing bio-polyols and biogenic polyisocyanates. Bio-based pentamethylene polyisocyanate (PDI-T), with 70% biogenic carbon content, is a prepolymer commercialized for bio-PU production. However, its production route has not yet been widely reported. Thus, herein, a theoretical study was conducted to investigate the manufacturing process of a novel bio-PU gel using castor oil and PDI-T. The biogenic production of PDI-T from molasses was designed. A comprehensive assessment integrating process modelling and simulation, cost estimation, economic analysis, and life-cycle assessment (LCA) methodologies was performed to evaluate the techno-economic and environmental performance of the produced bio-PU. This process showed a molasses-to-PU yield of 0.2 t<sub>bio-PU</sub> t<sub>molasses</sub><sup>−1</sup>, with the economic viability reaching a selling price of $15 000 per ton, <em>i.e.</em>, five-times higher than the price of a conventional PU-gel. Cradle-to-gate LCA showed a global warming potential (GWP) of 22.8 kg CO<sub>2</sub>e per kg bio-PU, which is four-times higher than the GWP reported in the Ecoinvent database for conventional PU. This methodology allowed the identification of key limitations negatively impacting GWP and production costs, primarily the complexity of bio-PDI-T synthesis, which involves high energy consumption and cumulative emissions from multiple raw materials. This study highlights that substituting fossil-based components with high biogenic carbon alternatives does not always result in climate benefits. Therefore, applying this methodology is pivotal for identifying truly sustainable pathways or suggesting modifications to existing processes, to achieve effective green chemistry transition.</div></div>","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":"27 19","pages":"Pages 5507-5530"},"PeriodicalIF":9.3,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fe leaching was identified as diffusion-controlled, while the leaching of other elements was primarily governed by chemical reactions.

To answer the expectations of analytical chemists, we propose a new tool that solves this problem in a simple and user-friendly way. The Red Analytical Performance Index (RAPI) presented in this article is inspired by the Red-Green-Blue assessment model, in which the red colour represents analytical criteria. A simple, open-source software (mostwiedzy.pl/rapi) is used to assess the given method in relation to the ten pre-defined criteria. The performance in particular criteria is scored (0, 2.5, 5.0, 7.5, or 10 points), with the sores mapped to colour intensity and saturation where 0 is white and 10 is dark red. A star-like pictogram is automatically created, and divided into fields related to the particular criteria, with the final, mean quantitative assessment score (0–100) in the middle. It thus shows similarities to the Blue Applicability Grade Index (BAGI) – a recently published “sister” tool dedicated to practical criteria represented by the blue colour. Therefore, RAPI and BAGI can support and supplement known greenness assessment metrics, providing key information about functional characteristics, crucial for the method application. The use of RAPI was demonstrated using examples of various analytical methods, which were assessed in parallel using BAGI and the greenness metrics showing the closest analogy. This provided a comprehensive picture of the varied methods’ characteristics. We believe that RAPI will prove to be an effective and useful support for analytical chemists in methods evaluation and comparison.</div></div>","PeriodicalId":78,"journal":{"name":"Green Chemistry","volume":"27 19","pages":"Pages 5546-5553"},"PeriodicalIF":9.3,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143938119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using lipase as a model enzyme, the resulting biocomposites present higher catalytic activity compared to their well-exploited lipase@ZIF-8 counterpart, which is also synthesized by a traditional mechanochemical approach. Additionally, Zn-HHTP can shield the encapsulated enzymes against environmental stressors, showing enhanced pH- and thermal stability.
