Abstract In this work, the MCM-48 mesoporous material was prepared and characterized to apply it as an active adsorbent for adsorption of 4-nitroaniline (4-Nitrobenzenamine) from wastewater. The characterizations were specified by implementing various techniques such as; scanning electron microscopy (SEM), Energy dispersive X-ray analysis (EDAX), diffraction (XRD), Brunauer–Emmett–Teller (BET) surface area, pore size distribution (PSD), Fourier transform infrared (FTIR). batch results showed that very equilibrium analyzed applying isotherms like Langmuir, Freundlich, Temkin. maximum experimental uptake according type I Langmuir found be 90 mg g −1 approximately. model with determination coefficient R 2 = 0.9965 is superior than Freundlich 0.99628 Temkin 0.9834. kinetic investigated pseudo 1st order, 2nd Intraparticle diffusion model. demonstrated regression coefficients are so high 0.9949, mean order hypothesis mechanism process appears well-supported. findings kinetics studies indicate a chemisorption physical process.

Investigate the use of visible light to improve photocatalytic degradation organic pollutants in wastewater. Nitrogen-doped titania and molybdenum sulfide nanocomposites (NTM NCs) with different weight ratios MoS2 (1, 2, 3 wt.%) synthesized by a solid state method applied photodegradation methylene blue(MB) under irradiation. The NTM composites were characterized SEM, TEM, XRD, FT-IR, UV-Vis, DRS PL spectroscopy. results showed enhanced activity hybrid nanocrystals oxidizing MB water irradiation compared pure TiO2. performance samples increased content. show that efficiency TiO2 compound improved from 13 82% presence N-TiO2 99% containing N-TiO2, which is 7.61 times higher than Optical characterization nanocomposite absorption region long lifetimes between e/h+ at optimal N-TiO2/MoS2 (NTM2) ratio. Reusable experiments indicated prepared NCs photocatalysts stable during had practical applications for environmental remediation.

Biocompatible Calcium Ion-Doped Magnesium Ferrite Nanoparticles as a New Family of Photothermal Therapeutic Materials for Cancer Treatment

Pharmaceutics, Год журнала: 2023, Номер 15(5), С. 1555 - 1555

Опубликована: Май 21, 2023

Novel biocompatible and efficient photothermal (PT) therapeutic materials for cancer treatment have recently garnered significant attention, owing to their effective ablation of cells, minimal invasiveness, quick recovery, damage healthy cells. In this study, we designed developed calcium ion-doped magnesium ferrite nanoparticles (Ca2+-doped MgFe2O4 NPs) as novel PT treatment, good biocompatibility, biosafety, high near-infrared (NIR) absorption, easy localization, short period, remote controllability, efficiency, specificity. The studied Ca2+-doped NPs exhibited a uniform spherical morphology with particle sizes 14.24 ± 1.32 nm strong conversion efficiency (30.12%), making them promising therapy (PTT). vitro experiments showed that had no cytotoxic effects on non-laser-irradiated MDA-MB-231 confirming biocompatibility. More interestingly, superior cytotoxicity laser-irradiated inducing cell death. Our study proposes novel, safe, high-efficiency, therapeutics treating cancers, opening new vistas the future development PTT.

Abstract From the perspective of environmental protection, highly efficient degradation antibiotics and organic dyes in wastewater needs to be tackled as soon possible. In this study, an ecofriendly green cube-shaped cobalt-doped zinc oxide nanoparticles (Co–ZnO NPs) photocatalyst using Pterocladia Capillacea (P. Capillacea) water extract loaded with 5, 10, 15% cobalt ions were formed via co-precipitation process degrade antibiotics. The prepared Co–ZnO NPs tested a for photodegradation ciprofloxacin (CIPF) presence visible LED-light source. have been obtained through method P. capping agent reducing agent, first time. Several characterization techniques including FTIR, XRD, BET, XPS, TEM, EDX, SEM, TGA DRS UV–Vis spectroscopy applied study NPs. XRD results suggested that average size these ranged between 42.82 46.02 nm hexagonal wurtzite structure. Tauc plot shows optical energy bandgap ZnO (3.19 eV) gradually decreases 2.92 eV by Co doping. Examinations showed 5% was highest catalyst CIPF when compared other 10 A mg/L solution photo-degraded (100%) within 15 min irradiation. kinetics first-order model is suitable displaying rate reaction amount elimination R 2 = 0.952. Moreover, central composite design optimization Co-doped also investigated.
