Origin of Pressure-Induced Metallization in Cu3N: An X-ray Absorption Spectroscopy Study
(Wiley-VCH Verlag, 2018)
High-pressure (0–26.7 GPa) Cu K-edge X-ray absorption spectroscopy is used to study possible structural modifications of anti-perovskite-type copper nitride (Cu3N) crystal lattice. The analysis of X-ray absorption near-edge ...
Transition levels of acceptor impurities in ZnO crystals by DFT-LCAO calculations
(Institute of Physics Publishing, 2018)
Large scale ab-initio calculations are carried out to study the charge state transition levels of nitrogen and phosphorus impurity defects in zinc oxide crystals using the DFT-LCAO approximation as implemented into the ...
Theoretical investigations of nitrogen doping on Co 3 O 4 for water dissociation catalytically activity
(Institute of Physics Publishing, 2018)
We report the results of theoretical investigations of nitrogen doping on Co 3 O 4 (100) bulk by means of the plane-wave periodic density functional theory (DFT) calculations combined with the Hubbard-U approach and ...
Novel method of phosphorescent strontium aluminate coating preparation on aluminum
(Elsevier Ltd, 2018)
This study presents a novel approach to produce phosphorescent coatings on metal surfaces. Strontium aluminates are the most popular modern phosphorescent materials exhibiting long afterglow at room temperature and a broad ...
Synthesis and vibration spectroscopy of nano-sized manganese oxides
(Polish Academy of Sciences, 2018)
X-ray diffraction, micro-Raman and the Fourier transform infrared spectroscopies as well as magnetometry measurements were performed on nanosized manganese oxides to probe their phase composition and magnetic properties. ...
X-ray excited luminescence of SrAl2O4:Eu,Dy at low temperatures
(Elsevier B.V., 2018)
Particle size effects on the structure and emission of Eu3+:LaPO4 and EuPO4 phosphors
(Elsevier B.V., 2018)
This paper provides the detailed study of (nano)particle's size effect on structural and luminescent properties of LaPO4:Eu3+ synthesized by four different methods: high temperature solid-state, co-precipitation, reverse ...
High resolution luminescence spectroscopy and thermoluminescence of different size LaPO4:Eu3+ nanoparticles
(Elsevier B.V., 2018)
Nanoparticles (5 nm) and nanorods (2 nm × 15 nm and 4 nm × 20 nm) of monoclinic monazite LaPO4:Eu3+ were prepared by reverse micelle and co-precipitation techniques. Effects of the particle size and surface defects on the ...
Development, Characterization, and Testing of a SiC-Based Material for Flow Channel Inserts in High-Temperature DCLL Blankets
(Institute of Electrical and Electronics Engineers Inc., 2018)
Flow channel inserts (FCIs) are the key elements in the high-temperature dual-coolant lead-lithium blanket, since in this concept the flowing PbLi reaches temperatures near 700 °C and FCIs should provide the necessary ...
Mechanical reinforcement of electrospun poly(vinyl alcohol) by α‐FeOOH nanowires
(Society of Plastics Engineers (SPE), 2018)
We report the mechanical performance of α‐FeOOH nanowire reinforced poly(vinyl alcohol) (PVA) composite nanofiber mat, fabricated using straightforward aqueous processing methods. Goethite (α‐FeOOH) nanocrystals have a ...
