(Vinca Institute of Nuclear Sciences, 2012)
A coupled thermo-mechanical model was developed to study the temperature fields, the plunge force and the plastic deformations of Al alloy 2024-T351 under different rotating speed: 350, 400, and 450 rpm, during the friction ...
Development and Validation of a Long-Term 3D Glioblastoma Cell Culture in Alginate Microfibers as a Novel Bio-Mimicking Model System for Preclinical Drug Testing
(Brain Sciences, 2021)
Background: Various three-dimensional (3D) glioblastoma cell culture models have a limited duration of viability. Our aim was to develop a long-term 3D glioblastoma model, which is necessary for reliable drug response ...
Zinc oxide nanoparticles prepared by thermal decomposition of zinc benzenepolycarboxylato precursors: Photoluminescent, photocatalytic and antimicrobial properties / Наночестични прахови цинк-оксида добијени термичком деградацијом цинк-бензенполикарбоксилато прекурсора: фотолуминесцентна, фотокаталитичка и антимикробна својства
(Serbian Chemical Society, 2020)
Zinc oxide (ZnO) nanoparticles were obtained by thermal decomposition of one-dimensional zinc-benzenepolycarboxylato complexes as single-source precursors at 450 °C in an air atmosphere. The mechanism and kinetics of thermal ...
Exploitation properties of ni-pd/al2o3 catalyst supported on ceramic foam
(Savez inženjera metalurgije Srbije, Beograd, 2015)
The goal of this research was to examine exploitation properties of Ni-Pd/Al2O3 catalyst supported on alpha-Al2O3 based foam in the dry methane reforming. The catalyst was prepared by using aerosol method. Chloride precursors ...
