However, to make them competitive with traditional plastics, biopolymers require certain modifications, including the addition of plasticizers and/or blending with other macromolecules. This study aims to develop biodegradable films using starch blended with chitosan, plasticized by choline chloride [Ch][Cl], and choline acetate [Ch][OAc], an ionic liquid derived from choline. The decision to exploit the plasticizer ability of bio-based ionic compounds depends on their excellent properties, such as non-volatility, biodegradability, and low toxicity. The research evaluates the effects of varying starch and chitosan fractions, as well as the two plasticizers, on the properties of the resulting films. Morphology, chemical composition, crystallinity, mechanical properties, thermal stability, and wettability are evaluated through different techniques, such as scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction analysis, thermogravimetric analysis, and performing mechanical and wettability tests. Characterization analyses highlight the primary influence of the anion on the properties of the different blends, suggesting the greater plasticizer capacity of the acetate anion.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e2500072"},"PeriodicalIF":3.0,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143956946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study reports the design and synthesis of dopant-free pyrazine-based HTMs. PS1 features a D-A-D type structure with pyrazine as the acceptor and 4,4'-dimethoxy triphenylamine (4,4'-OMe-TPA) as the donor, while PS2 adopts a D-π-A-π-D configuration with an additional thiophene unit as π- spacer along with 4,4'-OMe-TPA as donor. Both compounds were synthesized through a simple two-step synthetic procedure. These HTMS were subjected to structural, photophysical, electrochemical, theoretical, and photoelectrochemical studies with an emphasis on evaluation of structure-property relationships. Theoretical studies were conducted to explore the electronic distribution, optimized molecular structure, and frontier molecular orbitals (FMO). Their performance in perovskite solar cells was systematically evaluated without adding dopants. PS2 exhibited superior photoluminescence quenching compared to PS1, indicating more efficient charge transfer from the perovskite layer. Notably, PS2 achieved a PCE of 11.9%, surpassing the performance of PS1 (PCE of 10.15%). These findings highlight the potential of adjusting the electron-deficient core and π-bridge units as an effective strategy to optimize the properties of HTMs and improve their performance in PVSCs applications.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500124"},"PeriodicalIF":3.0,"publicationDate":"2025-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143953847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, the results of UOR indicate that Complex 1 only requires 1.30 V potential to achieve the same current density which is significantly lower than other counterparts and most reported materials.

Although the introduction of cosolvents with low polarities could improve the viscosity and operating temperature range, the multisolvent electrolyte system still endures low conductivity and high desolvation energy as well as the high production cost. This work introduces the acetone (ACT) as monosolvent for low-temperature electrolyte, which shows the medium dielectric coefficient (ε = 20.9), low donor number (10.67), and ultralow melting point. These properties guarantee its strong ion-dissociation ability for rapid ion-transportation in the bulk electrolyte, and weakened ion-solvent interaction for speeding desolvation process, as well as the outstanding temperature range of liquid phase. The supercapacitor with ACT-based electrolyte exhibits superior capacitance retention ratio (86.5% from 20 to -70 °C), high cycling stability (97.75% after 13,000 cycles) and preeminent power density and energy density (3776 W kg-1 @ 14.16 W h kg-1). Besides, the ACT solvent also displays the merits of low biological toxicity and low production cost, which further enhance its application prospect in the energy storage systems.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e2500142"},"PeriodicalIF":3.0,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143963795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the macroscopic behaviors have been extensively studied, molecular-level mechanisms remain in debate, limiting the ability to control interfacial phenomena effectively. This review examines the active structures and molecular mechanisms of these substances in heavy oil, elucidating the unique behaviors of molecules such as asphaltenes and colloids in the oil phase and at phase interfaces. The study reveals how molecular structures, hydrogen bonding, π-π stacking, and external conditions affect their interfacial properties, and summarizes strategies for regulating interfacial behaviors by adjusting molecular interactions. By providing new perspectives on the molecular behavior of interfacially active substances, this review establishes a scientific foundation for developing more efficient interfacial regulation strategies. These insights address specific issues in heavy oil extraction and processing while promoting broader advancements in molecular interface science, potentially guiding technological innovations in the energy and petrochemical industries.","PeriodicalId":148,"journal":{"name":"ChemPlusChem","volume":" ","pages":"e202500064"},"PeriodicalIF":3.0,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143951360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
