Pseudocapacitors are electrochemical energy storage devices and are utilized to fulfill the growing demand of the society. In this connection, donor-acceptor commands are attractive alternatives to inorganic materials die to their optoelectronic properties. Herein, a triphenylamine-anthraquinone based donor-acceptor chromophore was developed in electrode materials. As prepared electrode materials based on TPA-IM-AQ on graphite foil (GF) are employed to fabricate a three-electrode supercapacitor (SC) device in 1M H2SO4 electrolyte. At 0.5 A g-1 current density TPA-IM-AQ electrodes based SC can deliver higher specific capacitance (Csp) of 275.72 F g-1 at 0.5 A g-1 current density and at 5 mV s-1 scan rate with Csp of 233.63 F g-1. Moreover, two-electrode symmetric supercapacitor (SSC) exhibited Csp of 91.63 F g-1 at 0.5 A g-1 with energy density as high as 16.49 Wh kg-1 at a power density of 1079.96 W kg-1. The TPA-IM-AQ/GF based device exhibits good Csp retention with 88.40% after 5000 cycles at 3 A g-1. As-fabricated TPA-Im-AQ/GF electrode demonstrated the advantages of utilizing small organic molecule to achieve wider operational potential window and higher specific capacitance.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e202500723"},"PeriodicalIF":3.9,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143672998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prospective life cycle assessment (pLCA) provides a systematic approach to evaluating emerging technologies throughout their life cycle and projecting impacts at future industrial scales. This review aims to identify critical aspects of pLCA methodologies and examine their implementation in recent case studies. Key aspects are highlighted: assessment of initial technology maturity, upscaling methods to model data at higher technology readiness levels, and development of future scenarios to contextualize the scaled-up systems. Specific upscaling techniques such as process simulation, engineering calculations and technology learning curves are discussed. Approaches to generating future scenarios in line with integrated assessment models and common socio-economic pathways are also analyzed. An in-depth literature review covering 2021-2024 publications categorizes 79 articles into literature reviews, methodological papers and pLCA case studies. The identified critical issues serve as a benchmark to assess the completeness and robustness of 20 case studies. Notable contributions, limitations and the need for comprehensive guidelines that integrate scenario development with upscaling methods are highlighted. This review provides valuable insights for researchers conducting pLCA studies of emerging technologies and materials.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e202500304"},"PeriodicalIF":3.9,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143661688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Separation and identification of enantiomers are critical for a broad range of compounds, and discriminating stereoisomers in solution remains a key analytical challenge. Nuclear Magnetic Resonance (NMR) with Matrix-Assisted Diffusion-Ordered Spectroscopy (MAD), in the presence of chiral resolving agents, has emerged as a tool to explore these chiral mixtures. However, insight into the intermolecular interactions that lead to chiral recognition is still limited. Here, we combine experimental MAD studies with computational approaches to investigate the enantioselective discrimination of Mandelic Acid (MA) enantiomers using (R)-BINOL and (S)-BINOL. Molecular dynamics simulations explain the differences in diffusion coefficients for heterochiral complexes. Furthermore, quantum mechanical calculations confirmed enantioselective binding preferences due to differences in Gibbs free energies, highlighting the fundamental interactions and structural criteria that explain the NMR shielding and the diffusion trends. This integrated approach bridges experimental and theoretical studies, offering a comprehensive understanding of chiral recognition mechanisms and elucidating the observed heterochiral preference of BINOL for MA enantiomers. Our findings advance the field of chiral analysis and lay a foundation for future developments for identifying stereoisomers and recognition modes underlying enantioselective binding.","PeriodicalId":144,"journal":{"name":"Chemistry - A European Journal","volume":" ","pages":"e202404694"},"PeriodicalIF":3.9,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143661690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
