Hence, in this article we introduce a comparative study between 1% Si and 1% Nb-doped ZnO properties. The structural investigation proves the successful preparation of Si and Nb- doped ZnO. In addition, the impedance spectra of Nb-doped ZnO are well adjusted using an equivalent circuit formed by serial contributions of two parallel resistance R and constant phase element (CPE). Thus, we demonstrate that the capacitive behavior is due to improved grain boundary effect. While ZnO:Si impedance spectra are modeled by a circuit formed by a parallel connection of a resistance R and a capacitance C. In addition, ZnO:Nb exhibits thermally activated DC conductivity, while ZnO:Si conductivity is quasi-independent of temperature. With Si doping, dielectric properties shift to those of an insulator. Moreover, the obtained results prove Nb-doping can be a promising route to make ZnO a good candidate for applications as thermistor with a Negative Temperature Coefficient (NTC). In addition, Si, Nb doped ZnO show excellent photocatalytic performances in methylene blue degradation, that reached 97% under solar light illumination for 105 min. This makes them promising candidates for wastewater purification.</p>","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"72 3","pages":"317-332"},"PeriodicalIF":1.6,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689124","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}

Protein folding involves a delicate interplay between short-range (secondary) and long-range (tertiary) interactions, which together dictate the thermodynamic and kinetic properties of the system. In this study, we employ a mean-field framework to investigate these interactions using three progressively refined models. The regular model considers only short-range, nearest-neighbor interactions and reveals a cooperative folding transition driven by localized secondary interactions, consistent with standard two-state folding behavior. The Bryngelson–Wolynes (BW) model incorporates stochastic nonlocal interactions, demonstrating long-range cooperativity and introducing energy landscape ruggedness that shifts the folding transition. The modified Bryngelson–Wolynes (M-BW) model integrates both short-range and long-range effects, leading to the emergence of a hysteresis loop characteristic of first-order-like phase transitions, even in finite systems. These results suggest that the interplay between secondary and tertiary interactions is sufficient to induce phase transition-like properties in proteins. By providing a unified framework, this study highlights how simplified models can elucidate the complex dynamics of protein folding, misfolding, and aggregation, offering critical insights into the underlying mechanisms of these fundamental biological processes.</p>","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":"72 3","pages":"247-256"},"PeriodicalIF":1.6,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688708","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}
