Influence of Co2+ ions on photocatalytic properties of MgFe2O4 ferrites
(Belgrade : Institute for Multidisciplinary Research, 2019)
In this work, spinel magnesium cobalt ferrites (CoxMg1-xFe2O4, x = 0.0, 0.1, 0.3, 0.5, 0.7, 0.9) were synthesized by a sol-gel combustion method. Magnesium nitrate, cobalt nitrate and iron nitrate were used as oxidizers ...
NIR photo-driven upconversion in amino and carboxyl functionalized NaYF4:Yb,Er particles for in vitro cancer cell imaging
(London : Conference Series IIc, 2019)
Lanthanide-doped fluoride up-converting nanoparticles (UCNPs) represent the imaging contrast agents which hold great potential for overcoming existing problems associated with traditionally used dyes, proteins and quantum ...
Humidity sensing potential of iron manganite (FeMNO3)
(Budapest : [s. n.], 2019)
Though different metal oxide systems have been investigated and applied in humidity sensing as resistive or capacitive ceramic humidity sensors new materials remain the subject of much research. Iron manganite (FeMnO3) has ...
The effect of mechanical activation on synthesis and properties of MgAl2O4 ceramics
(Societa ceramica italianaPolitecnico di Torino, 2019)
Magnesium aluminate, MgAl2O4, and other alumina-based spinels are refractory ceramics with high hardness and resistance to chemical attack while also being possible microwave dielectrics. Pure MgAl2O4 can be optically ...
Nanocrystalline SnO2-Zn2SnO4 composite thick films applied as humidity sensors
(Belgrade : Institute for Multidisciplinary Research, 2019)
Starting ZnO and SnO2 nanopowders (<100 nm) were mixed in a suitable ratio and calcined at 1050 °C for 2 hours to obtain nanocrystalline SnO2-Zn2SnO4 composite powder. Structural characterization performed by X-ray diffraction ...
Application of magnetite/3D-printed wollastonite hybrid sorbent for As(V) removal from water
(Belgrade : Serbian Ceramic Society, 2019)
The maximal allowed concentration (MAC) for As(V) in water decreased from 50 to 10 μg/l, by considering the harmful effects of arsenic on the environment and human health. In order to achieve the established rigorous ...
Structural, photocatalytic and photoelectrochemical characteristics of ZnO nanoparticles synthesized by a glycine-nitrate process
(Budapest : [s. n.], 2019)
Zinc oxide is a semiconductor material which still, after a century of scientific research, shows great potential in modern day utilisements such as heterogenous photocatalysis of organic pollutants and as a photoanode ...
Effect of Mechanical Activation on the Densification Behavior of MgAl2O4 Spinel
(The Ceramic Society of Japan, 2019)
Magnesium aluminate and other alumina-based spinels attract attention due to their high hardness, high mechanical strength, and low dielectric constant. MgAl2O4 was produced by solid-state reaction between MgO and a-Al2O3 ...
Structure and photocatalytic properties of sol-gel synthesized pseudobrookite
(Novi Sad : Faculty of Technology, 2019)
Fe2TiO5 nanopartcles were synthesized by modified sol-gel method with aid of
Fe(NO3)3 9H2O and Ti(OC3H7)4 as starting reagents, oxalic acid as chilate agent and cetyltrimethylammonium bromide as surfactant. The aim of ...
