Experimental and theoretical study of visible light driven scandium (III) doped ZnO for antibacterial activity

Synthesis of Fe-doped ZnO/biochar nanocomposites for acid orange 7 photodegradation and antibacterial activity under visible light region

“…After solidification of the EMB agar, 10 μl of the photocatalytic degradation solution was evenly inoculated onto a Petri dish and placed in a specialized bacterial incubator at 37 °C for 24 h. The number of E. coli colonies in the Petri dish was counted using a colony counter. The antibacterial rate (η%) was determined using the following formula [43]:…”

Preparation and Properties of (Sc2O3-MgO)/Pcl/Pvp Electrospun Nanofiber Membranes for the Inhibition of Escherichia coli Infections

“…On the other hand, there are many kinds of active sites on the surface of Sc 2 O 3 -MgO, such as lattice limited hydroxyl, free hydroxyl, and ion holes, which can be used as adsorption and surface reaction centers and cause mechanical damage. Scandium (Sc 3+ ) has been shown to have the ability to inhibit the growth of Klebsiella pneumoniae, E. coli, and Pseudomonas aeruginosa [40][41][42]. The purpose of doping Sc 3+ in the nano-MgO lattice is to increase the lattice defects and then increase the ROS content produced during the antibacterial process to enhance the antibacterial property of MgO.…”

Erbium ion implantation into LiNbO3, Al2O3, ZnO and diamond – measurement and modelling – an overview

“…48 Overall, to our knowledge, there are no theoretical studies focusing on the different possible locations of dopants in the ZnO structure -dopants/impurities are always localized in the Zn substitutional site. [49][50][51][52][53] Theoretical simulations of Er-doped ZnO were done rarely so far. [54][55][56] From the study of Alkahtani et al 54 it was found that the incorporation of Er into ZnO affects considerably the electronic and optical properties of ZnO; the optical energy band gap increased by 83% together with a red shift of the optical spectra with Er doping, indicating the importance of the 4f donor occupied states of erbium ions.…”
