This paper proposes a novel hybrid powder-based additive manufacturing method to fabricate 3D biomass-derived laser-induced graphene (3D B-LIG) structures with customizable geometries and microporous features. This method utilizes two waste sources as feedstock precursors for sustainable graphene production: “black liquor” (sodium lignosulfonate, NaLS) and “white pollution” (polypropylene, PP). Employing a computer-aided design process, this method allows for the synchronous creation of various freeform macrostructures, with either identical or variable sections. To optimize the formability and processing efficiency of 3D B-LIG, systematic studies have been conducted. These studies establish the relationship between processing parameters and the resulting structures by controlling the laser parameters and the mixing ratio of NaLS and PP. By leveraging tunable microporous structures with a maximized specific surface area of 485.3 m2 g−1, 3D B-LIG demonstrates exceptional performance in pollutant adsorption (with a maximum adsorption capacity of 283.3 mg g−1 for methylene blue) and energy storage (with a gravimetric specific capacitance value of 194.9 F g−1).","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":null,"pages":null},"PeriodicalIF":7.1,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142266346","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}

To stabilize Si anodes, this work reports the design, synthesis, and application of a conducting/crosslinked poly(BIAN) (P‐BIAN) as a polymer binder for Si anodes. Theoretical evaluation of crosslinked P‐BIAN and electrochemical characterization of anodic half‐cells show that the crosslinked P‐BIAN exhibits its versatility by a) administering mechanical robustness to stabilize Si particles, b) undergoing n‐doping owing to the low‐lying lowest unoccupied molecular orbital (LUMO) to tailor a thin solid‐electrolyte interphase (SEI), and c) maintaining electrical conductivity.

While bio‐oils are known to soften asphalt, their specific impact on these properties is less understood. The study evaluates four different bio‐oils (B1–B4) derived from various waste vegetable sources to determine their influence on asphalt performance. The findings indicate that bio‐oils with higher purity and lower polyunsaturated fatty acid content offer better resistance to heat and UV‐induced degradation. Bio‐oils with lower iodine values also show improved resistance to moisture damage. Notably, bitumen composites containing bio‐oil B2 do not negatively affect asphalt's moisture resistance, while others increase its moisture susceptibility. Tests with liquid anti‐strip agents reveal that silanes and amine‐based agents are the most effective at reducing moisture damage. These results underscore the importance of selecting bio‐oils with low acid and iodine values, low polyunsaturated fatty acid content, and high purity for use in asphalt. This study supports sustainability and resource conservation by recommending bio‐oils that preserve the durability of bio‐modified asphalts.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":null,"pages":null},"PeriodicalIF":7.1,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142224786","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}

However, this multi-electron reduction process requires an efficient electrocatalyst to overcome the kinetic barrier. Herein, the Pt2Cu1 nanooctahedrons are synthesized through a liquid-phase chemical reduction process. The synergistic effect of bimetallic Pt and Cu sites in the Pt2Cu1 nanooctahedrons is indispensable for accelerated NO2− hydrogenation, originating from the strong hydrogen-atoms adsorption capacity at Pt site and the strong NO2− adsorption capacity at Cu site. Specifically, the introduction of Pt sites can accelerate the accumulation of hydrogenated species on the catalyst surface, which promotes the formation of NH3. In 0.5 m Na2SO4 solution, the Pt2Cu1 nanooctahedrons can reduce NO2− to NH3 at a yield of 4.22 mg h−1mgcat−1 and a Faraday efficiency of 95.5% at a potential of −0.14 V versus RHE. Meanwhile, the Pt2Cu1 nanooctahedrons also exhibit excellent activity for the sulfion oxidation reaction (SEOR). Using Pt2Cu1 nanooctahedrons as bifunctional electrocatalyst, a coupled electrolysis system combining the nitrite electrochemical reduction reaction (NO2−ERR) with the SEOR requires only 0.3 V total voltage, enabling energy-saving electrochemical NH3 production and collective value-added recovery of nitrite and sulfion waste.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":null,"pages":null},"PeriodicalIF":7.1,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142224784","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}
