These N-CDs exhibited a maximum emission wavelength of 486 nm when excited at 358 nm. They demonstrated significant antioxidative properties in various concentrations of H₂O₂ and showed high photostability and resistance to photobleaching under different pH, ionic strength, and UV irradiation conditions. Furthermore, the N-CDs were validated as highly selective and sensitive fluorescence sensors for MnO₄⁻ ion, demonstrating a linear relationship within the concentration range of 0.5–168 uM with a detection limit of 41.8 nM.

To improve the characteristics of a drilling fluid, properties such as rheological, filtration, and stability are of prime concern. In the current study, hydrothermal technique was used to support the rutile crystal form of TiO₂ by activated carbon prepared using a waste material. The particle was added in quantity of 0.35, 0.875, 1.75, 2.625, and 3.5 g, respectively. Results of the study reveal no significant changes in the mud densities when the modified particle was added in the base mud. Moreover, all samples exhibited pseudo-plastic behavior with rheological properties in a range of API recommended standards. All the rheological characteristics were on the lower side because the rutile crystal has a smaller surface area and lower active sites. Furthermore, mud starts to dephase at a rapid pace and completely loses its stability within 6 h of experimentation. The larger grain dimensions and small number of pores of the rutile crystal form have some adverse influence on the surface area, which decreases the stability of the system. In addition, the carbon-supported rutile-TiO₂ composite demonstrated high fluid loss volume with mud cakes having higher permeability, thicker in dimension, and containing a significantly larger number of fractures after 24 h of drying. At 0.25 wt%, the particle demonstrated a minimum fluid loss volume of 31 mL/30 min, which increased to 47 mL/30 min as the concentration was twice.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"79 5","pages":"2911 - 2923"},"PeriodicalIF":2.2,"publicationDate":"2025-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143930099","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}
