Leaching of Cs-137 from spent ion exchange resins in cement-bentonite clay matrix
(Acta Chimica Slovenica, 2003)
The leaching rate of Cs-137 from the spent cation exchange resins in cement-bentonite matrix has been studied. The solidification matrix was a standard Portland cement mixed with 290350 (kg/m(3)) spent cation exchange ...
Immobilization of Cs-137 in concrete
(Acta Chimica Slovenica, 2003)
To assess the safety for disposal of radioactive waste-cement-bentonite composition, the leaching of Cs-137 from a waste composite into a surrounding fluid has been studied. Leaching tests were carried out in accordance ...
Interactive Effects of Insulin and beta-Estradiol on Protein Kinase B Phosphorylation in Adult Rat Cardiomyocytes
(Acta Chimica Slovenica, 2009)
Insulin (INS) and beta-estradiol (E(2)) have vascular effects partially through stimulation of protein kinase B (Akt) phosphorylation. Employing adult rat cardiomyocytes (ARC), the effects of acute (15 min) stimulation ...
Photocatalytic deposition of gold on nanocrystalline TiO2 films
(Acta Chimica Slovenica, 2008)
Nanocrystalline TiO2 films were prepared on glass supports by the dip coating technique using colloidal solutions consisting of 45 angstrom TiO2 particles as a precursor in order to probe the feasibility of exploiting solid ...
Concentrations of Rn-222 and Rn-220 in indoor air
(Acta Chimica Slovenica, 2008)
Radon (Rn-222) and thoron (Rn-220) were surveyed in indoor air of 15 public buildings and 10 homes in Slovenia in November 2004 by exposing Rn-Tn discriminative etched track detectors. The following ranges of the activity ...
Combustion Synthesis and Characterization of CeO2 Nanopowder
(Acta Chimica Slovenica, 2008)
Modified combustion procedure, named as polymer complex solution method (PCS), was used for synthesis of CeO2 nanopowder. As fuel was employed polyethylene glycol (PEG) with average molecular weight 200. Post-synthesis ...
Nanodesigning of SiO2 : Eu3+ particles obtained by spray pyrolysis method and their luminescence properties
(Acta Chimica Slovenica, 2006)
Mechanism of droplet formation and the structuring of SiO2:Eu3+ spheres prepared by the process of ultrasonic spray pyrolysis, using colloidal solution consisting of the 7.5 mn SiO2 nanoparticles and Eu(NO3)(3)center dot ...
Properties of the (Y0.75Gd0.25)(2)O-3 : Eu3+ scintillating nanopowder
(Acta Chimica Slovenica, 2008)
Yttrium-gadolinium-oxide phosphors are regarded promising host for many important optical applications, for example in medical diagnostic X-ray systems and plasma displays. In this work, we investigated the procedure for ...
Discrimination between normal and malignant breast tissues by synchronous luminescence spectroscopy
(Acta Chimica Slovenica, 2006)
Studies of fluorescence from endogenous molecules in tissues are common for applications such as detection or characterization of early disease. Breast cancer is one of the most common malignant tumor among women and good ...
Complex formation between Pd(II) and immobilized imidazol-azo-chromotropic acid
(Acta Chimica Slovenica, 2006)
1,8-Dihydroxy-2-(imidazol-2-ylazo)-naphthalene-3,6-disulphonic acid (imidazol-azo-chromotropic acid - IACA) was immobilized onto the anion exchange resin Dowex I-X8,50-100 mesh. The aim of this work was to investigate the ...
