Nanoindentation investigation of mechanical properties of ZrO2, ZrO2-Y2O3, Al2O3 and TiO2 thin films deposited on stainless steel OC 4O4 substrate by spray pyrolysis
(Elsevier, 2014)
Thin ZrO2, ZrO2-Y2O3, Al2O3 and TiO2 films were deposited by spray pyrolysis method on stainless steel DC 404 substrate with thickness 50 mu m. The thicknesses of obtained films varied from 0.50 to 0.64 mu m. The surface ...
The influence of different radiopacifying agents on the radiopacity, compressive strength, setting time, and porosity of Portland cement
(Springer Heidelberg, Heidelberg, 2014)
The aims of this study were to evaluate the radiopacity, compressive strength, setting time, and porosity of white Portland cement (PC) with the addition of bismuth oxide (Bi2O3), zirconium dioxide (ZrO2), and ytterbium ...
Electrooxidation of p-nitrophenol using a composite organo-smectite clay glassy carbon electrode
(Elsevier, 2014)
Bentonite clay rich in smectite clay mineral from seldom investigated locality Mecji Do (MD) in Serbia was modified. The organomodification was performed with different loadings of benzyltrimethylammonium (BTMA) cation. ...
Design and photocatalytic ability of ordered mesoporous TiO2 thin films
(Oxford : Pergamon-Elsevier Science Ltd, 2014)
Homogeneous and crack-free TiO2 films with templated mesoporosity were prepared by the dip coating technique using an evaporation-induced, self-assembly method. The synthesized mesoporous TiO2 films were characterized using ...
Identification of p53 and Its Isoforms in Human Breast Carcinoma Cells
(Hindawi Publishing Corporation, New York, 2014)
In breast carcinoma, disruption of the p53 pathway is one of the most common genetic alterations. The observation that the p53 can express multiple protein isoforms adds a novel level of complexity to the outcome of p53 ...
Dietary polysaccharide extracts of Agaricus brasiliensis fruiting bodies: chemical characterization and bioactivities at different levels of purification
(Elsevier, 2014)
Polysaccharides of the European strain of A. brasiliensis were obtained by hot water extraction and ethanol precipitation (HWPE I) of fruiting bodies, and further purified by dialysis (HWPE II) and pronase incubation (PPE). ...
Effect of UV/ozone treatment on the nanoscale surface properties of gold implanted polyethylene
(Elsevier, 2014)
The effect of ultraviolet (UV) ozone treatment on the surface properties of gold implanted high density polyethylene (HDPE) was investigated at a nanoscale using Atomic Force Microscopy (AFM). HDPE samples were modified ...
Parallel Water/Aromatic Interactions of Non-Coordinated and Coordinated Water
(Wiley-V C H Verlag Gmbh, Weinheim, 2014)
The parallel interactions of non-coordinated and coordinated water molecules with an aromatic ring were studied by analyzing data in the Cambridge structural database (CSD) and by using quantum chemical calculations. The ...
Removal of Tc-99(VII) by organo-modified bentonite
(Elsevier, 2014)
(99)Technetium is one of the largest components of nuclear waste material. In aqueous solutions Tc-99 is present as the pertechnetate oxoanion, (TcO4-)-Tc-99, which is highly soluble and mobile in groundwater under oxidizing ...
Catalytic activities of Pt thin films electrodeposited onto Bi coated glassy carbon substrate toward formic acid electrooxidation
(Elsevier, 2014)
Formic acid oxidation was studied on platinum-coated bismuth deposits on glassy carbon substrate. The catalyst was prepared by a two-step process using chronocoulometry, i.e. controlled amount of Bi was electrodeposited ...
