Influence of Sc substitution on the structure and properties of NASICON-type NaScR(PO) (R = Eu, Tb, Dy) phosphors.

NaScR(PO) (R = Eu, Tb, Dy; 0 ≤ ≤ 0.2) phosphors were synthesized by a high-temperature solid-state reaction. Sc : R ratios for the NSP:R samples were determined by ICP-MS, EDX-SEM and TEM-EDX measurements.

Bright UV-C Phosphors with Excellent Thermal Stability-YScPO Solid Solutions.

The structural and luminescence properties of undoped YScPO solid solutions have been studied. An intense thermally stable emission with fast decay (τ ~ 10 s) and a band position varying from 5.21 to 5.

Band Gap Engineering and Trap Depths of Intrinsic Point Defects in RAlO (R = Y, La, Gd, Yb, Lu) Perovskites.

The possibility of band gap engineering (BGE) in RAlO (R = Y, La, Gd, Yb, Lu) perovskites in the context of trap depths of intrinsic point defects was investigated comprehensively using experimental and theoretical approaches. The optical band gap of the materials, , was determined via both the absorption measurements in the VUV spectral range and the spectra of recombination luminescence excitation by synchrotron radiation. The experimentally observed effect of reduction from ∼8.

Distinctive features of diffusion-controlled radiation defect recombination in stoichiometric magnesium aluminate spinel single crystals and transparent polycrystalline ceramics.

MgAlO spinel is important optical material for harsh radiation environment and other important applications. The kinetics of thermal annealing of the basic electron (F, F) and hole (V) centers in stoichiometric MgAlO spinel irradiated by fast neutrons and protons is analyzed in terms of diffusion-controlled bimolecular reactions. Properties of MgAlO single crystals and optical polycrystalline ceramics are compared.

The use of artrofoon in the treatment of ankylosing spondyloarthritis.

In patients with ankylosing spondyloarthritis, artrofoon produced a more potent antiinflammatory effect than nonsteroidal antiinflammatory drugs. The study demonstrated a positive effect of artrofoon on clinical and laboratory parameters, good tolerability of the preparation, and the absence of negative effects on the hepatic and renal functions. Being added to complex therapy, artrofoon led to a decrease in the dose of nonsteroidal antiinflammatory drugs.
