Obtaining nano calcium phosphate/poly(dl-lactide-coglycolide) composite biomaterial by sonochemical deagglomeration
(Belgrade: Institute of Technical Sciences of SASA, 2007)
Nanoparticles have several advantages over the microparticles in interactions of thebiomaterial with the organism. The response of the organism depends on the interaction of thebiomaterial with the surrounding tissue and ...
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 ...
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. ...
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 ...
Frequency response analysis as a tool for fast evaluation of periodic operations. Case study: A heterogeneous catalytic reacator
(2nd European Process Intensification Conference (EPIC 2009), Venice, Italy, 2009)
One way to achieve process intensification is to operate the process in a periodic way, in
order to obtain better average performance compared to the optimal steady-state operation.
The source of the possible improvement ...
Fabrication and characterization of AFM golden microcantilevers and measurement of small electromagnetic forces
(Institute of Electrical and Electronics Engineers Inc., 2008)
This paper presents results of research oriented towards developing a method for measurement of small electromagnetic forces using atomic force microscope (AFM). The method is based on the measurement of cantilever deflection ...
