Photocatalytic degradation of wastewater polluted by methyl-tertiary-butyl-ether using titanium-dioxide and doped titanium-dioxide
(Proceedings of the 4th Iasme/Wseas International Conference on Water Resources, Hydraulics and Hydro, 2009)
The subject of this research was utilization of concentrated solar radiation simulated with a sodium lamp SONT UV100, in lab condition, on removal of wastewater polluted by methyl-tertiary-butyl-ether (MTBE). The effects ...
Photopyropiezoelectric elastic bending method
(AIP Publishing, 2003)
A method of investigation of semiconductors and metal–semiconductor structures based on two techniques: The elastic bending technique and pyropiezoelectric (PPE) technique was presented. The method was demonstrated on a ...
Preparation and properties of polymeric and composite bioresorbable barrier membranes
(Progress in Advanced Materials and Processes, 5th Conference of the Yugoslav-Materials-Research-Society (Yu-MRS 2003), Sep 15-19, 2003, Herceg Novi, Yugoslavia, 2004)
Bioresorbable barrier membranes have been widely used in dentistry and maxillofacial surgery. When the membranes are placed over bony defects and are closely adapted by the surrounding bone face, an environment that prevents ...
Photoacoustic spectroscopy: investigation of sputter damage in Si surface by Ar plasma
(Institute of Electrical and Electronics Engineers (IEEE), 2004)
The effect of Ar plasma etching on the surface of Si was investigated by photoacoustic spectroscopy. The surface of Si sample (p-tip, 10 k/spl Omega/cm, 420 /spl mu/m) was treated with Ar plasma from 2 min to 80 min. ...
Distribution and fractionation of heavy metals in the Tisa (Tisza) River sediments
(Springer Heidelberg, Heidelberg, 2007)
Introduction. In this work, sediments of the River Tisa (Tisza) are studied to assess their environmental pollution levels for some major heavy metals, as well as to predict the investigated elements' mobility on the basis ...
Similar bifidogenic effects of the infant formulae with added inuline and breast feeding on gut microflora
(Elsevier, 2009)
The purpose of this study was to determine if there is and what are the differences in the bifidogenic effects and gut microflora of breast-fed and formula-fed newborns (younger than 6 months and
children age from 6 to ...
Nanoscale topography of GC/Pt-C and GC/Pt-Ru-C electrodes studied by means of STM, AFM and XRD methods
(Materials Science Forum, 2006)
Electrodes, assigned as GC/Pt-C and GC/Pt-Ru-C, were formed by deposition of Pt-based catalysts (47.5 wt % Pt + high surface area carbon) and (54 wt. % Pt-Ru alloy + high surface area carbon) on glassy carbon (GC) discs. ...
