Abstract
<div>This study focused on the synthesis and characterization of monodisperse
spherical TiO<sub>2</sub> nanoparticles doped on the surface with Se (IV) in
order to increase the mechanical properties of the bonded joint reinforcing.
Work will begin with the synthesis of monodisperse quasi-spherical
TiO<sub>2</sub> nanoparticles with a modal diameter of less than 20 nm,
using the sol-gel technique. Se (IV) selenium surface doping changed the
specimen’s chemistry and physics. Different initial concentrations of the doping
element will be tested. Next, a physicochemical characterization of the
different solid systems will be carried out in order to determine the effect of
the doping element on the properties of titanium dioxide. Their morphology and
size will be studied through transmission electron microscope observations;
volume chemical composition by X-ray diffraction analysis, EDX
(energy-dispersive X-ray), and XRF (X-ray fluorescence). The careful selection
of 4% and 6% concentrations produced the optimum nanoparticle increase and
cohesive structure preservation. These findings demonstrate that Se (IV)-doped
monodisperse spherical TiO<sub>2</sub> nanoparticles may improve adhesive
junction mechanical properties, enabling the development of better adhesive
formulations.</div>
