Enhanced photocatalytic and antimicrobial performance of a multifunctional Cu-loaded nanocomposite under UV light: theoretical and experimental study

Abstract

Due to modern industrialization and population growth, access to clean water has become a global challenge. In this study, a metal–semiconductor heterojunction was constructed between Cu NPs and Co0.5Ni0.5Fe2O4/SiO2/TiO2 composite...

Cefotaxime incorporated bimetallic silver-selenium nanoparticles: promising antimicrobial synergism, antibiofilm activity, and bacterial membrane leakage reaction mechanism

“…The adjusted bacterial cells; according to standard 0.5 McFarland (2 × 10 8 CFU mL −1 ), were mixed with the synthesized bimetallic Ag–Se NPs (without and with CFM incorporation). Following the mixing, all tubes were UV-irradiated, and the antimicrobial potency of the UV-irradiated samples were tested against the most sensitive S. aureus through the method of the optical density, 41 and compared with the control non-UV irradiated samples.…”

“…The adjusted bacterial cells; according to standard 0.5 McFarland (2 Â 10 8 CFU mL À1 ), were mixed with the synthesized bimetallic Ag-Se NPs (without and with CFM incorporation). Following the mixing, all tubes were UV-irradiated, and the antimicrobial potency of the UV-irradiated samples were tested against the most sensitive S. aureus through the method of the optical density, 41 and compared with the control non-UV irradiated samples. The investigated tubes were classied into two conditions, tubes including non-UV irradiated the synthesized bimetallic Ag-Se NPs (without and with CFM incorporation), and tubes with the synthesized bimetallic Ag-Se NPs (without and with CFM incorporation) and UV-irradiated.…”

Magnetite/Reduced Graphene Oxide Synthesis and Study as a Potential Adsorbent for Absorptive Removal of Heavy Metals

“…Surface area and abundance of adsorption sites were comparatively high at low starting solution concentration, making it simple to adsorb and increase the heavy metal removal %. The total number of adsorption sites that are reachable is constrained at higher starting solution concentrations, which causes a reduction in the percentage of heavy metal ion removal [51,52].…”

Adsorption and separation of Cs(I) and Ba(II) from aqueous solution using zinc ferrite-humic acid nanocomposite

“…Natural exchanger materials, such as zeolites, different types of clay, and oxide materials, have been investigated and applied to remove radioactive wastes. Also, synthetic exchangers such as composite materials, polymeric materials, and porous materials have been of greatest interest for removing wastes [9][10][11][13][14][15][16][17] .Magnetic adsorbents get the feature of being efficiently recovered from the aqueous system by utilizing a magnetic field [18][19][20][21][22][23][24][25][26] . Spinel ferrites possess unique chemical and physical features that distinguish them from their bulk form; hence they are often utilized as adsorbents.…”
