Investigation of structural, microstructural and magnetic properties of YbxY1-xF3 solid solutions
(Journal of Physics and Chemistry of Solids, 2020)
In this investigation, we have synthesized YbxY1-xF3 solid solutions by fluorination of yttrium and ytterbium sesquioxides with ammonium hydrogen difluoride. According to the XRD analysis, all synthesized YbxY1-xF3 samples ...
On the presence of antisite defect in monoclinic Li2FeSiO4 – A combined X-Ray diffraction and DFT study
(Solid State Sciences, 2019)
Li2FeSiO4 material, which was prepared by a solid state method, crystallized as monoclinic P21/n polymorph. X-ray diffraction analysis with Rietveld structural refinement indicates specific occupation of Li2 crystallographic ...
Inducing LIPSS on multilayer thin metal films by femtosecond laser beam of different orientations
(Optical and Quantum Electronics, 2020)
The occurrence of laser-induced periodic surface structures (LIPSS) has been known for a while. Multilayer thin films, like Al/Ti, are suitable for LIPSS formation and attractive for applications—due to their wearing ...
Theoretical and experimental investigation of geometry and stability of small potassium‐iodide KnI(n=2–6) clusters
(International Journal of Quantum Chemistry, 2019)
Small heterogeneous potassium-iodide clusters are investigated by means of ab initio electronic structural methods together with experimental production and detection in mass spectrometry. Experiments were done by using ...
Quantum primary rainbows in transmission of positrons through very short carbon nanotubes
(Elsevier, 2016)
This paper is devoted to a quantum mechanical consideration of the transmission of positrons of a kinetic energy of 1 MeV through very short (11, 9) single-wall chiral carbon nanotubes. The nanotube lengths are between 50 ...
Rainbow channeling of protons in very short carbon nanotubes with aligned Stone-Wales defects
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2016)
In this paper proton channeling through armchair single-walled-carbon-nanotubes (SWCNTs) with aligned Stone-Wales defects has been investigated. The energy of the proton beam was 1 GeV, while the lengths of the SWCNTs have ...
Proton-silicon interaction potential extracted from high-resolution measurements of crystal rainbows
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2015)
This study provides a way to produce very accurate ion atom interaction potentials. We present the high-resolution measurements of angular distributions of protons of energies between 2.0 and 0.7 MeV channeled in a 55 nm ...
Archaeometric study of 17th/18th century painted pottery from the Belgrade Fortress
(Journal of Cultural Heritage, 2018)
The chemical and mineralogical composition of ceramic bodies, glazes and pigments, as well as the firing temperatures of main groups of Austrian period painted pottery excavated at the Belgrade Fortress on the territory ...
Increased plasma phosphatidylcholine/lysophosphatidylcholine ratios in patients with Parkinson's disease
(Rapid Communications in Mass Spectrometry, 2020)
Rationale: Changes in lipid composition might be associated with the onset and progression of various neurodegenerative diseases. Herein, we investigated the changes in the plasma phosphatidylcholine (PC)/lysophosphatidylcholine ...
Total Mercury Levels in Commercial Fish in Market of the Republic of Srpska, Bosnia and Herzegovina
(Biological Trace Element Research, 2020)
The mercury concentration was quantified in frozen and canned fish found in the market of the Republic of Srpska, Bosnia and Herzegovina. Using the method of amalgamation by atomic absorption spectrophotometry with a direct ...
