    “…Initially, a series of the different composites between TiO(2) nanoparticles and CuFe(2)O(4) nanoparticles are synthesized by a sol–gel “ex situ” method to enhance the catalytic activity of bare nanomaterials toward the visible region of the electromagnetic spectrum. X-ray diffraction reveals the presence of characteristic patterns for the tetragonal structure in the bare materials or TiO(2)@CuFe(2)O(4) NCs; however, the dominance in the phase as well as intensity of the respective XRD reflections in the NCs is observed according to the content of TiO(2) or CuFe(2)O(4) in the NCs. …”

    “…While neuroimaging is ideal for obtaining such critical information, existing modalities have been limited due to poor resolutions, along with significant noise interference from the electromagnetic spectrum. In this study, we used a novel diffuse optical tomography (DOT) device in order to advance our understanding of the neurophysiological effects of rTMS in depression. …”

    “…The Photolumincence (PL) peaks were observed at around 355 nm for pure LiNbO(3)/Si and 358, 360, 363, 371, 476 nm for different immersion durations respectively, in the visible region of the electromagnetic spectrum. The scanning electron microscopy (SEM) study illustrated that with increasing the immersion time, especially at 45 s, a change in the particle morphology was observed (LiNbO(3) NRs structure). …”
