Examination of the doping effects of samarium (Sm3+) and zirconium (Zr4+) on the photocatalytic activity of TiO2 nanofibers
(Elsevier, 2023)
Pure and samarium (Sm3+) - or zirconium (Zr4+)-doped TiO2 nanofibers were synthesized by electro-
spinning method followed by calcination at 500 °C for 1 h. As-spun fibers were smooth, straight and
continuous, whilst ...
Molecular-dynamics simulations of the nanoscale Taylor test under extreme loading conditions
(SAGE Publications, 2016)
A series of molecular-dynamics simulations of the classic Taylor impact test is performed by using a flat-ended monocrystalline nanoscale projectile made of the Lennard-Jones two-dimensional solid. The nanoprojectile ...
Titanium doped yttrium manganite: improvement of microstructural properties and peculiarities of multiferroic properties
(Springer, 2022)
Yttrium manganite, YMnO3, was doped with different concentrations of titanium (x = 0, 0.04, 0.08, 0.10, 0.15, 0.20) in order to improve the microstructural and multiferroic properties. The powders were prepared using sol-gel ...
Apple pectin-derived oligosaccharides produce carbon dioxide radical anion in Fenton reaction and prevent growth of Escherichia coli and Staphylococcus aureus
(Elsevier Science Bv, Amsterdam, 2017)
Pectin is the main soluble fiber in apples or citruses. It may be fermented by gut microbiota to metabolites showing local intestinal and systemic effects. A wide range of beneficial effects of dietary pectin includes ...
Humidity sensing properties of nanocrystalline pseudobrookite (Fe2TiO5) based thick films
(Elsevier Science Sa, Lausanne, 2018)
Pseudobrookite based nanopowder was obtained by solid state synthesis of starting hematite and anatase nanopowders in the weight ratio 55:45. Structural and morphological properties were analyzed using X-ray diffraction ...
Impact of Microstructure on Humidity Influence on Complex Impedance of Iron Manganite
(IEEE Computer Society, 2020)
This work deals with our continued research of oxide materials for potential application in gas/humidity sensing. We have made thick film samples using iron manganite powder synthesized by a so/-gel combustion method with ...
Fabrication and characterization of luminescent Pr3+ doped fluorapatite nanocrystals as bioimaging contrast agents
(Amsterdam : Elsevier, 2020)
Fluorapatite doped with rare-earth elements has a wide-range of biomedical applications. Here, a new type of fluorapatite nanocrystals doped with praseodymium (FAP-Pr) with excitation-emission profiles in visible part of ...
Reactions of superoxide dismutases with HS-/H2S and superoxide radical anion: An in vitro EPR study
(Academic Press Inc Elsevier Science, San Diego, 2015)
Interactions of hydrogen sulfide (HS-/H2S), a reducing signaling species, with superoxide dimutases (SOD) are poorly understood. We applied low-T EPR spectroscopy to examine the effects of HS-/H2S and superoxide radical ...
Shattering impact fragmentation of slender nanoprojectiles
(Springer, Dordrecht, 2019)
Molecular dynamics simulations of the rigid-anvil collision test are performed to achieve the complete pulverization of slender nanoprojectiles. The simulation setup mimics the traditional Taylor test (the flat-ended ...
Accumulation of metal trace elements in different body parts of terrestrial Roman snail Helix pomatia L., 1758 on three polluted sites in Serbia
(Springer, 2022)
Atmospheric pollution remains one of the growing concerns in the twenty-first century, with particular focus on metal trace elements (MTE) from anthropogenic sources, due to their adverse effects on biota. The concentration ...
