Production, Microstructure and Tribological Properties of Zn-Al/Ti Metal-Metal Composites Reinforced with Alumina Nanoparticles
(International Journal of Metalcasting, 2021)
The investigated metal-metal composites were produced by the compocasting process using the standard zinc-aluminium alloy ZA-27 as a matrix and titanium microparticles (particle size approx. 10 μm) as a secondary phase. ...
Nanoparticle shapes: Quantification by elongation, convexity and circularity measures
(Journal of Electrical Engineering, 2019)
The goal of the nanoparticle synthesis is, first of all, the production of nanoparticles that will be more similar in size and shape. This is very important for the possibility of studying and applying nanomaterials because ...
Structural, morphological and luminescence properties of nanocrystalline up-converting Y1.89Yb0.1Er0.01O3 phosphor particles synthesized through aerosol route
(Journal of Alloys and Compounds, 2013)
Nanocrystalline up-converting Y₂ O₃Yb³⁺ Er³⁺ phosphor particles were processed in a dispersed system-aerosol, generated ultrasonically at 1.3 MHz from common nitrate precursor solution having fixed ytterbium-to-erbium ...
Erosive wear properties of ZA-27 alloy-based nanocomposites: Influence of type, amount, and size of nanoparticle reinforcements
(Friction, 2019)
Metal matrix nanocomposites (MMnCs) comprise a metal matrix filled with nanosized reinforcements with physical and mechanical properties that are very different from those of the matrix. In ZA-27 alloy-based nanocomposites, ...
Crystal Structure and Magnetocaloric Effect of La0.80Ag0.15MnO3 Nanoparticles
(Acta Physica Polonica A, 2020)
Annealing of_ non stoichiometric La0.80Ag0.15MnO3 nanoparticles leads to the change of the crystal symmetry from Pnma to R3c and to almost doubling of its Curie temperature from 117 K to 317 K. This effect is due to the ...
Controversies related to real protection against SARS-CoV-2 virus of the most frequently used face masks
(Zaštita materijala, 2022)
Face masks serve to protect the respiratory system from unwanted aerosol droplets, in which various types of pathogens or pollutants are present. They are particularly important during a pandemic, like SARS-CoV-2 pandemic ...
MgTiO 3:Mn 4+ a multi-reading temperature nanoprobe
(RSC Advances, 2018)
MgTiO3 nanoparticles doped with Mn4+, with homogeneous size ranging about 63.1 ± 9.8 nm, were synthesized by a molten salt assisted sol gel method. These nanoparticles have been investigated as optical thermal sensors. The ...
Characterization of NiO nanoparticles prepared using gelatin and a low-cost synthesis / Karakterizacija NiO nanočestica pripremljenih pomoću želatina tokom postupka 'low-cost' sinteze
(Vojnotehnički glasnik, 2019)
Nanocomposite material containing NiO nanoparticles decorated on WO3 nanowires could be used for monitoring levels of H2S gas. The effectiveness of this material is mostly determined by NiO properties. The performed study ...
Drug Delivery Systems for Diabetes Treatment
(Current Pharmaceutical Design, 2019)
Background: Insulin is essential for the treatment of Type 1 diabetes mellitus (T1DM) and is necessary in numerous cases of Type 2 diabetes mellitus (T2DM). Prolonged administration of anti-diabetic therapy is necessary ...
Luminescence Thermometry with Nanoparticles: A Review
(Nanomaterials, 2023)
Luminescence thermometry has emerged as a very versatile optical technique for remote temperature measurements, exhibiting a wide range of applicability spanning from cryogenic temperatures to 2000 K. This technology has ...
