Effect of Yttria-Stabilized Zirconia Concentration in an Electroless Bath on Microstructure and Composition of Ni/Yttria-Stabilized Zirconia Nanocomposite.

The effect of the yttria-stabilized zirconia (YSZ) nanoparticle loading in an electro-less bath was considered as one of the vital synthesis variables for control Ni content and microstructure of prepared nanocomposite particles, which are two crucial factors to achieving high-performance SOFC anode. Nanocomposite particles were prepared using a simple electroless method without any expensive pretreatment of sensitizing by Sn²+ ions as well as activating by Pd ions that are usually used to apply nickel coating on the surface of a non-conductive substrate. The process was performed by adding YSZ nanoparticles into NaOH solution, separating them from the solution by the centrifugal method, then providing several water-based nanofluids with different concentrations of activated YSZ nanoparticles, mixing them with NiCI₂ solution, followed by adding the hydrazine and then NaOH solution.

A pH-responsive citric-acid/α-cyclodextrin-functionalized FeO nanoparticles as a nanocarrier for quercetin: An experimental and DFT study.

Developing new nanocarriers and understanding the interactions between the drug and host molecules in the nanocarrier at the molecular level is of importance for future of nanomedicine. In this work, we synthesized and characterized a series of iron oxide nanoparticles (IONPs) functionalized with different organic molecules (citric acid, α-cyclodextrin, and citric acid/α-cyclodextrin composite). It was found that incorporation of citric acid into the α-cyclodextrin had negligible effect on the adsorption efficiency (<5%) of citric acid/α-cyclodextrin functionalized IONPs, while the isotherm adsorption data were well described by the Langmuir isotherm model (q = 2.

Nano-Biphasic Calcium Phosphate Ceramic for the Repair of Bone Defects.

Calcium phosphate bioceramics has recently experienced increased interest in bone reconstruction. Mimicking of natural structure of bone, like the use of nanomaterials, is an attractive approach for generating scaffolds for bone regeneration. The aim of present study was to evaluate the effect of nanonization on the biphasic calcium phosphate (BCP) ceramic in the repair of bone cavities in the canine mandible.
