Our study is focused on the structural and morphological characteristics, optical behaviour photocatalytic properties of undoped 5 at% Eu3+-, Gd3+- Y3+-doped CeO2 nanoparticles prepared by a green hybrid sol-gel combustion method. Several techniques such as X-ray diffraction powder (XRD), Transmission Electron Microscopy (TEM), UV-Vis spectroscopy, Photoluminescence spectroscopy (PL) Paramagnetic Resonance (EPR) have been used to investigate obtained samples. Moreover, correlation between...
This study presents the synthesis of sintered composite foams based on Invar alloy (64Fe-36Ni), using hollow spherical particles from a nickel superalloy (NiCrSiB) in order to generate porosity. The powder was obtained by mechanical alloying (MA), and NiCrSiB were incorporated into at 20 vol %. sintering realized spark plasma (SPS) process an argon atmosphere 600 °C 5 MPa, with 10 s holding time. porous structures structurally characterized optical microscopy (OM), scanning electron (SEM)...
This manuscript presents the preparation and characterisation of fibres-based soft magnetic composites that incorporates a secondary phase such as carbonyl Fe Mn–Zn ferrite nanopowder. Amorphous Fe77.7Si7.5B15 at.% fibres were coated with dielectric layer ZnO via thermal evaporation. SEM-EDX investigations revealed evaporation technique leads to complete coating having thickness 150–250 nm demonstrated STEM-EDX analysis. The hybrid cold sintering/spark plasma sintering was used for first...
Abstract The development of systems for targeted delivery Sorafenib in unresectable hepatocellular carcinoma to reduce the systemic toxicity is a challenge. In our article, we successfully prepared core‐shell microcapsules based on bovine serum albumin gel with polyelectrolyte complex multilayer shell polysaccharides opposite charges, hyaluronic acid, and chitosan, encapsulating Sorafenib, as targeting system improved therapy. A core was formed by method sacrificial CaCO 3 template, followed...
Our study is focused on optimizing the synthesis conditions for in situ oxidation of Fe particles to produce Fe@Fe3O4 core-shell powder and preparation via co-precipitation ZnFe2O4 nanoparticles Fe@Fe3O4/ZnFe2O4 soft magnetic composites (SMC) through a hybrid cold-sintering/spark plasma-sintering technique. XRD FTIR measurements confirmed formation nanocrystalline oxide layer surface nanosized nature nanoparticles. SEM-EDX investigations revealed that oxidic phase our composite was...
