In this study, the ionic conductivity of NASICON-structured materials Li3(Zr,Ti)2(Si,Ge)2PO12 are explored through ab initio molecular dynamics (AIMD) simulations. This investigation reveals the significant impact of isovalent substitution on the lithium-ion diffusion pathways and the associated energy barriers. Elemental substitutions, such as replacing Zr with Ti, significantly reduce the Li site energy levels, enhance the polyhedral volume, and change the coordination structure from four-coordinate to five-coordinate, thereby facilitating lithium-ion migration. Conversely, substituting Si with Ge reduces the diffusion channel size and increases fluctuation of Li migration potential surface, leading to less favorable ion transport conditions. Li3Ti2Si2PO12 exhibits a room temperature ionic conductivity of 5.79 × 10−2 Scm−1, 163% higher than that of the pristine Li3Zr2Si2PO12, with a reduced diffusion barrier of 0.16 eV. Additionally, these analyses reveal that the critical size for effective diffusion channels is vital: below this threshold, ion migration is suppressed; while above it, the channel size no longer limits migration.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 4","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840552","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 investigates the influence of different etching media on the synthesis of 2D Cr2CTx MXene derived from cost-effective Cr2AlC MAX phase. Three etching solutions- hydrofluoric acid (HF), HF-forming (lithium fluoride + Hydrochloric acid, LiF+HCl), and non-fluoride (sodium hydroxide, NaOH) have been used to treat ternary carbide Cr2AlC MAX phase under varied reaction conditions. The MXenes, Cr2CTx-HF, Cr2CTx-LiF/HCl, and Cr2CTx-NaOH are structurally, and morphologically characterized using XRD, Raman spectroscopy, TGA, XPS, SEM-EDX, and BET-BJH analysis. The electrochemical performance of Cr2CTx MXene is assessed, focusing on its performance in water splitting and supercapacitive applications. The materials exhibit lower overpotential values for hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and demonstrate improved pseudocapacitive behavior, with enhanced energy and power densities. The introduction of surface termination groups in Cr2CTx MXene (Tx = ─F, ─OH, ─O) resulted in a more open and accessible layered structure with an appreciable surface area, without any modifications. This enhanced electrochemical kinetics, improved ion transport, diffusion, and storage capacity, which are beneficial for electrochemical energy storage and production.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 4","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840943","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 proposes an optimized method for recycling bifacial solar panels, which lack a back sheet and use ethylene-vinyl acetate (EVA) as the sole encapsulant. The process achieves 100% recovery of valuable materials, including polymerized oil, clean glass, solar cells, and copper tape. Unlike traditional PV panels with back sheet polymers like PVF, PET, or PVDF, bifacial panels simplify the recycling process. EVA, composed of hydrogen, carbon, and oxygen, is more environmentally friendly, especially without fluorinated compounds. Using a modified pyrolysis reactor, the EVA layer is degraded in inert conditions, minimizing emissions and producing polymerized oil. This oil can be used as a lubricant, while the recovered glass, solar cells, and copper tape are reusable in manufacturing new panels. Optimized oil yield is achieved using Response Surface Methodology (RSM) and Box-Behnken Design (BBD). At a heating rate of 8.92 °C min−1, a 31.82-min hold time, and a maximum temperature of 528.22 °C, the process yields 57.53% polymerized oil. The oil is characterized by thermogravimetric analysis (TGA) and Fourier-transform infrared spectroscopy (FT-IR), meeting ASTM and Australian diesel standards. This method maximizes material recovery and supports a circular economy, enhancing solar energy system sustainability.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 4","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840688","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}

In this work, the stability of different alginate hydrogels semi-interpenetrated with poly(3,4-ethylenedioxythiophene):polystyrene sulfonate conducting polymer (Alg/PEDOT), which acts as a photothermal absorber is examined. More specifically, the behavior of Alg/PEDOT hydrogels ionically and covalently crosslinked with Ca2+ ions and glyoxal, respectively, has been compared when used as water purification platforms. The homogenous porosity and higher cycling capacity of the glyoxal-crosslinked gels provide superior performance for water-steam generation under sunlight irradiation than that of the ionically stabilized gel. Furthermore, increasing the glyoxal cross-linking reaction time prove to have little effect on the porosity and the efficiency of freshwater supply from an artificial seawater solution. Covalent cross-links provide thermal absorber (PEDOT:PSS) retention capacity in artificial seawater, which is critical to maintaining such efficiency with the increasing number of purification cycles. This research opens new frontiers to promote the use of alginate biopolymer in chemical engineering processes such as water desalination, directly addressing the United Nations Sustainable Development Goals for Clean Water & Life on Land.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 4","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840686","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}

Among the various modification strategies, separator modification offers a promising approach to address issues on both anodes and cathodes. In this study, a bifunctional asymmetric polypropylene (PP) separator is modified with nitrogen-doped reduced graphene oxide (N–rGO) on the cathode side and cellulose fibers (CF) on the anode side to address the challenges associated with both electrodes. CF effectively promotes the uniform deposition of lithium metal and significantly inhibits the growth of lithium dendrites. In addition, N–rGO with a porous structure and nitrogen-doped active sites can not only suppress lithium polysulfide shuttling by physical and chemical adsorption but also catalyze the kinetics of the redox reaction, leading to an increased specific capacity of the battery. The Li─S battery incorporating N–rGO@PP@CF separator exhibits an impressive specific capacity of 1294 mAh g−1 at a current rate of 1 C, with a remarkably low average capacity decay of 0.076% per cycle over 500 cycles.

The integrated Van der Waals (vdW) engineering and morphology engineering hold the potential to effectively boost hydrogen evolution on MoS2. Herein, hierarchical nanotubes (MoS2/N-doped-C) assembled from MoS2 nanosheets sandwiched by N-doped-C layers are synthesized utilizing an integration of hydrothermal and annealing.

To address this gap, we first developed an integrated framework comprising 357 indicators for 297 Chinese cities through a literature review. Nevertheless, the sheer number of reviewed indicators presents significant challenges in data collection. The study then used principal component analysis and multiple regression to identify a small set of SDG indicators (principal indicators) with the consideration of data collection difficulty. Finally, we tested their effectiveness up to 2030. The key findings of our study are as follows: 1) 187 principal indicators are identified to explain the 90% variance of all the 357 indicators with lowest data collection difficulty, providing comprehensive coverage of the SDGs and achieving efficient information aggregation; 2) these principal indicators demonstrated good variance effectiveness and data availability in the vast majority of cities (284 out of 297), highlighting priority areas for future data infrastructure development; 3) the continued applicability of these principal indicators up to 2030 is validated.
