Structural, Optical, Surface and Gas-Sensing Properties of rGO/Sn1-xZnxO₂ Nanocomposites
Abstract: rGO/Sn₁₋ₓZnₓO₂ nanocomposites with x = 0.00–0.75 were synthesized by sol–gel auto-combustion followed by wet impregnation with reduced graphene oxide. The adopted synthesis route enabled homogeneous Zn incorporation into the SnO₂ matrix and uniform distribution of rGO, leading to improved structural integrity and interfacial contact between the two components. XRD confirmed a dominant tetragonal cassiterite SnO₂ structure, while FTIR, FESEM, EDS, UV–visible, and BET analyses verified oxide–rGO coupling, Zn-dependent structural modification, …

Characterization of Antibacterial and Biofilm Inhibition in Tin and Zinc Oxide Nanoparticle-Doped Orthodontic Composites
Abstract: Background: This study investigated the antibacterial effectiveness of orthodontic adhesive enhanced with stannous oxide (SnO₂) nanoparticles against Lactobacillus acidophilus and Streptococcus mutans, in comparison to traditional adhesives without nanoparticle infusion. Methods: A modified orthodontic adhesive was prepared by incorporating 1% w/w of tin dioxide and zinc oxide nanoparticles (SnO₂ + ZnO₂ NPs) into Transbond XT. This nanoparticle-enhanced composite was used to fabricate discs for assessing antibacterial activity against Lactobacillus acidophilus …
