Spherical shaped nanoparticles of series Y(2 - x)Eu(x)O(3) (x = 0.06, 0.10, 0.20, and 2) and Gd(2 - x)Eu(x)O(3) (x = 0.06, 0.10) were prepared by thermolysis of 2,4-pentanedione complexes of Y, Gd, and Eu. The bixbyite phase of Gd(2 - x)Eu(x)O(3) samples was formed at 500 degrees C, whereas the thermal decomposition of Y and Eu complexes' mixtures occurred at higher temperatures. Linearity in t...

5-Ethynyluracil (5-EU; 776C85) is a potent mechanism-based inactivator of dihydropyrimidine dehydrogenase that improves the antitumor activity of 5-fluorouracil (5-FU) to a greater extent than can be accounted for by the improved 5-FU pharmacokinetics that result from preventing the catabolism of 5-FU. We therefore tested the effects of (R)-5-fluoro-5,6-dihydrouracil (5-FUH2), the 5-FU cataboli...

Optical absorption spectra of KBr:Tl + (0.01mol%) single crystals shows A, B and C bands around 258, 220 and 210nm respectively. An additional absorption bands are observed in KBr-KI: Eu 2+ , Tl + (0.05, 0.01mol %) mixed crystals. These additional absorption spectra are attributed to the presence of Eu 2+ aggregates and complex centers involving both Eu 2+ and Tl + ions. Inclusion of Tl + ions ...

The title compound, Eu(5)Cd(2)Sb(5)O adopts the Ba(5)Cd(2)Sb(5)F-type structure (Pearson symbol oC52), which contains nine crystallographically unique sites in the asymmetric unit, all on special positions. One Eu, two Sb, and the Cd atom have site symmetry m..; two other Eu, the third Sb and the O atom have site symmetry m2m; the remaining Eu atom has 2/m.. symmetry. Eu atoms fill penta-gonal ...

BACKGROUND The Eastern border of the European Union (EU) consists of 10 countries after the expansion of the EU in 2004 and 2007. These 10 countries border to the East to countries with high tuberculosis (TB) notification rates. We analyzed the notification data of Europe to quantify the impact of cross-border TB at the Eastern border of the EU. METHODS We used TB surveillance data of 2010 su...

M2SiO4-based phosphors (M: alkaline-earth metal) that emit red to blue light are expected to offer high color rendering to white light-emitting diodes (LEDs) in combination with blue or near-UV excitation sources. It is very important for the complete control of the emission color to understand the crystal field around the active elements (rareearth and transition metals). XAFS spectroscopy is ...

The interaction between the plenary Keggin H3PW12O40, lacunary Keggin K7PW11O39 and the Eu(III)-substituted Keggin K4EuPW11O39 (Eu-Keggin) type polyoxometalates (POMs), and the proteins human and bovine serum albumin (HSA and BSA) was studied using steady state and time-resolved Eu(III) luminescence and tryptophan (Trp) fluorescence spectroscopy. The excitation spectrum of the Eu-Keggin POM is ...

AIM To perform a comparative analysis of the pharmaceutical pricing and reimbursement systems in Croatia and the 27 European Union (EU) Member States. METHODS Knowledge about the pharmaceutical systems in Croatia and the 27 EU Member States was acquired by literature review and primary research with stakeholders. RESULTS Pharmaceutical prices are controlled at all levels in Croatia, which i...

We report on the first measurement of the Eu isotope fractions (Eu and Eu) in s-process element–enhanced metal-poor stars. We use these ratios to investigate the Sm branching of s-process nucleosynthesis. The measurement was made by detailed study of Eu ii lines that are significantly affected by hyperfine splitting and isotope shifts in spectra of the carbon-rich very metal poor stars LP 625 4...
