Chemical and radiochemical characterization of depleted uranium in contaminated soils
(Maik Nauka/Interperiodica/Springer, New York, 2007)
The main results of chemical and radiochemical characterization and fractionation of depleted uranium in soils contaminated during the Balkan conflict in 1999 are presented in the paper. Alpha-spectrometric analysis of ...
Characterization and catalytic activity of poly(4-vinylpyridine-co- divinylbenzene)-Co2+ complex
(Materials Science Forum, 2005)
Poly(4-vinylpyridine-co-divinylbenzene)-Co2+ was characterized using infrared spectroscopy (IR), thermogravimetric analysis (TG-DTA), N 2-physisorption and polarography. Thermal analysis suggests sufficient thermal stability ...
Kvalitet podzemnih voda u području Zapadnobačkog okruga / The Quality of Underground qaters in the Region of West Bačka
(Beograd (Serbia): Udruzenje za tehnologiju vode i sanitarno inzenjerstvo, 2007)
The population and the industry in the region of West Backa are supplied with underground water which is specific in its quality due to higher content of organic substance, higher pH values, the presence of hydrogen-sulphide ...
Investigation of SiO/sub 2/ film on Si substrate by photoacoustic method
(Institute of Electrical and Electronics Engineers (IEEE)IEEE, 2004)
The effect of SiO/sub 2/ film on Si substrata (SiO/sub 2//Si) was investigated by photoacoustic spectroscopy. The amplitude and phase spectra were measured and analyzed in dependence on the wavelength of excitation optical ...
Investigation of silicon anisotropic etching in alkaline solutions with propanol addition
(Institute of Electrical and Electronics Engineers Inc., 2008)
Different propanol isomers additives to 26 wt. % KOH water solution have been studied. It was stated that addition of both isomers result in changing etching anisotropy of (110) oriented corners on Si LT 100 >. For the ...
Photoacoustic elastic bending method: Investigation of the surface recombination states
(26th International Conference on Microelectronics, Proceedings, MIEL 2008, 2008)
The recombination processes of surface modified Si samples by the PA elastic bending method were investigated. The experimental PA elastic bending signals were measured by using special constructed PA cell (the gas-microphone ...
Sulphation of CaO-based sorbent modified in CO2 looping cycles
(Proceedings of the 20th International Conference on Fluidized Bed Combustion, 2009)
CaO-based looping cycles for CO2 capture at high temperatures are based on cyclical carbonation of CaO and regeneration of CaCO3. The main limitation of natural sorbents is the loss of carrying capacity with increasing ...
Metal-dielectric photonic crystal for the enhancement of solar-blind ultraviolet silicon photodiodes
(Institute of Electrical and Electronics Engineers Inc., 2008)
We report the fabrication of metal-dielectric photonic crystals as bandpass filter for the UV riadiation with a sidelobe suppression in excess of 4 orders of magnitude. The metal-dielectrics were designed for the enhcancement ...
Vacuum MEMS sensor based on thermopiles - Simple model and experimental results
(Institute of Electrical and Electronics Engineers Inc., 2008)
This paper presents a simple model of MEMS thermopile based vacuum detector and experimental results obtained for sensors designed and fabricated at IHTM-IMTM. Sensors contain two thermopiles, each with 30 multilayer ...
Metal nanowire arrays with ultralow or negative effective permittivity for adsorption-based chemical sensing
(Institute of Electrical and Electronics Engineers Inc., 2008)
We investigated wire-mesh media with plasma-like dispersion of dielectric permittivity as a potential medium for nanoplasmonic sensors utilizing adsorption of chemical, biochemical or biological analytes. Such structures ...
