Enhanced Photocatalytic Degradation of Reactive Dyes Under Visible Light Using ZnO/CdS/Co Nanocomposites: A Step Toward Advanced Environmental Remediation.

In this study, ZnO, CdS, ZnO/CdS, and ZnO/CdS/Co nanostructures were successfully synthesized using a simple chemical precipitation method. The formation of these nanostructures was confirmed through x-ray diffraction (XRD), but their morphological properties were analyzed using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Their optical properties were investigated using UV-visible diffuse reflectance spectroscopy (UV-DRS) and photoluminescence spectroscopy (PL).

Flower like-novel nanocomposite of Mg(TiSn)Odecorated on reduced graphene oxide (rGO) with high capacitive behavior as supercapacitor electrodes.

In this study, ceramic materials of Mg(TiSn)Owere synthesized and decorated on reduced graphene oxide, forming a nanocomposite of rGO/Mg(TiSn)O(rGO/MTS001). The successful synthesis results were confirmed by XRD, UV-vis analysis, FT-IR, and SEM-EDS. The MTS001 has a flower-like morphology from scanning electron microscopy (SEM) analysis, and the nanocomposites of rGO/MTS001 showed MTS001 particles decorated on the rGO's surface.

Excellent Characteristics of Environmentally Friendly 3D-Printed Nasopharyngeal Swabs for Medical Sample Collection.

3D-printed nasopharyngeal swabs for medical sample collection have been manufactured via additive manufacturing (AM), evaluated, and characterized in the present study. A multi-part component of nasopharyngeal swabs was proposed, in which the swab and handle were manufactured separately to reach sustainable production and environmentally friendly products. The swab was investigated using tensile, flexural, surface roughness, dimensional accuracy, and sample collection testing.
