Pure cubic ZrO2 nanoparticles by thermolysis of a new precursor

Improvement of the Superconducting Properties of Ho123 Nanoparticles via a Polymer Mediated Sol-Gel Method

“…3d revealed that the re-calcination process leads to complete decomposition of BaCO 3 phase. The observed broad peaks at around 3430 cm −1 and weak peaks at about 1630 cm −1 in all spectra are assigned to the stretching and bending vibrations of the absorbed water on the surface of the sample, respectively [14][15][16]. The nanoparticles assemblies are formed through the heating process.…”

Morphologies and magnetic properties of FeCo nanoparticles modulated by changing the types of ligands of Co

“…1 shows the schematic structures of these final products. Instrumental details for FT-IR, SEM, XRD, Elemental Analysis, TEM, EDX, AGFM spectroscopy were the same as described earlier [30][31][32][33].…”

“…Precipitation from solution is a simple method to prepare magnetic nanoparticles with a rigorous control over their size and shape [24][25][26][27][28][29]. At the moment, a major interest is in the development of organometallic or inorganic complexes for the synthesis of nanostructures [30][31][32][33]. In this work, we synthesized FeCo nanoparticles by ultrasound-assisted co-precipitation method due to the enhanced dispersion of active components [34].…”

Synthesis and electrical field-assisted sintering behaviour of yttria-stabilized tetragonal ZrO2 nanopowders by polyacrylamide gel method

“…At atmospheric pressure, pure ZrO 2 has three solid polymorphs: monoclinic, i.e., thermodynamically stable at the temperatures below 1175 • C, tetragonal, stable at the temperature range of 1175-2370 • C, and cubic, stable above 2370 • C [4,5]. The tetragonal form can be retained in a metastable state at room temperature by adding various oxides, in particular yttria or by decreasing the particle size below a certain critical size [6][7][8].…”
