An emerging topic of our days is nanoscience and nanotechnology successfully applied in the food industry. Characteristics such as size, surface area and morphology can modify the basic properties and the chemical reactivity of the nanomaterials. The brea... see more

Cerium oxide nanoparticles (CeO2 nanoparticles) as nanomaterials have promising biomedical applications. In this paper, the cytotoxicity induced by CONPs human cervical tumor cells was investigated. Cerium oxide nanoparticles were synthesized using the pr... see more

A low-temperature hydrothermal synthesis technique was employed as a medium to produce ceria-zirconia mixed oxides particles at temperatures of 200–300 °C and pressure of 10 MPa in a batch process. At these conditions, the average crystallite sizes of cer... see more

Synthesis and certification of lanthanum oxide extracted from monazite sand have been carried out. This research aimed to increase the added value of monazite sand and obtain the lanthanum oxide in-house certified reference material (CRM). Synthesis of la... see more

In the last 20 yr, the production of nanoparticles has increased, although their effects on organisms and the environment are not well understood. This research evaluated the transfer of cerium oxide (nano-CeO2) nanoparticles in a terrestrial trophic chai... see more

Sm0,20Ce0,80O2 powder was used for the formation of samarium doped cerium oxide (SDC) thin films using e-beam. Surface area of powder was 34.9 m2/g and particle size – 0.3-0.5 µm. Thin films were deposited using physical vapor deposition system on SiO2 an... see more

In the present work antibacterial effect of NCO (Nano-Cerium Oxide) particles on E.Coli (Escherichia Coli) Bacteria was studied. NCO (Nano Cerium Oxide) particles were synthesized via microwave induced combustion method. XRD (X-Ray Diffraction), SEM (Scan... see more

Weakly agglomerated zirconium dioxide nanopowders stabilized by complex oxides of scandium (III) and cerium (IV) were synthesized by precipitation from aqueous solutions. Using weakly agglomerated nanopowders, thick films were prepared by tape casting on ... see more

The catalytic systems without noble metal on the base of oxides of copper, chromium and cerium in the catalytic dehydration of bioethanol to ethylene were studied and compared. It was found that all the studied catalysts regardless of the nature of the me... see more
