Revisiting the factors influencing the magnetic resonance contrast of Gd₂O₃ nanoparticles

Abstract

Gadolinium oxide nanoparticles (GONs) have the potential to be one of the best candidates for the contrast agents of magnetic resonance imaging. Even though the influence of parameters on the...

Synthesis of Gadolinium-Doped Molybdenum Diselenide Nanospheres for Ultrasensitive Electrochemical Determination of Essential Amino Acid in Human Serum and Milk Samples

“…Figure 3b represents the high resolution of the Gd 4d core-level spectrum exhibited the peak at 145 eV and 152 eV, respectively due to the presence of Gd trivalent ion. 35 Figure 3c observed the Mo 3d spectrum initiates the primary doublet peaks at 232.3 eV and 235 eV which is well assigned to the Mo 3d 5/2 and Mo 3d 3/2 peaks and the broad peak at 238 eV indicates the presence of Mo 6+ due to the MoO 4 2− reduction in the synthesis process. Figure 3d displays the binding energy of the Se 3d core -level spectrum was observed at 56.6 eV which corresponds to Se 3d 3/2 .…”

“…The individual peak at 1400 cm −1 was associated with the Gd-O bond stretching which confirms the doping of Gd 3+ on MoSe 2 . 34,35 XPS was used to characterize the valence state of the electronic configuration and elemental composition of the Gd@MoSe 2 structure. Figure 3a shows the Gd@MoSe 2 survey of the XPS spectrum was tested by the presence of O, C, Gd, Mo, and Se elements.…”

Erbium oxide nanoplates as a sonosensitizer devoid of photosensitivity

“…Er 2 O 3 nanoplates were synthesized by following a modified thermal decomposition method. 30,31 Briefly, an erbium oleate precursor was synthesized by simply mixing erbium chloride with sodium oleate. The precursor was then heated in a mixture of oleic acid (OA), oleylamine (OM), and 1-octadecene (ODE) at 330 1C.…”
