Isolation, selection and adaptation of zymogenous microorganisms: a basis of successful bioremediation
(Belgrade : Serbian Chamber of Commerce, Board of Environmental Protection and Sustainable Development, 2006)
The paper presents the results of ex-situ bioremediation of soil on a pilot heap (halde) within the grounds of Petroleum Refinery Pančevo, Serbia.
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 ...
Photothermal vibration spectra of square diaphragm with boss for low-pressure sensor
(26th International Conference on Microelectronics, Proceedings, MIEL 2008, 2008)
The low-pressure sensors (IHTM-CMTM, SP-6) with square diaphragms and concentric bosses were investigated by the photothermal elastic vibration method. The photothermal vibrations were optically excited (the focused laser ...
Sputtered nickel coverage of the SiO2 nano-step
(Institute of Electrical and Electronics Engineers Inc., 2008)
In this paper we give a survey of the problems that we encountered during deposition and examination of the Ni layers on SiO2 nano-step. We made nano-layer Of SiO2 and deposited Ni film on top of it thus making particular ...
Non-contact measurement of thickness uniformity of chemically etched Si membranes by fiber-optic low-coherence interferometry
(Institute of Electrical and Electronics Engineers Inc., 2008)
In this paper we present a contactless technique for thickness measurement of chemically etched Si membranes. This technique is based on low-coherence interferometry performed by single-mode fiber-optic sensing configuration. ...
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 ...
The state of nickel in the silver modified NiMg/SiO2 vegetable oil hydrogenation catalysts
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Two series of silver modified Ni-Mg materials were synthesized by precipitation-deposition on SiO2 support derived from two silica sources: diatomite activated at 800°C (Series a; Mg/Ni = 0.1 and SiO 2/Ni = 1.07) and ...
Investigation of the interface states in the SiO2– Si system by photoacoustic method
(EDP Sciences, 2005)
The interface states in SiO2 - Si system was investigated by photoacoustic (PA) spectroscopy. The amplitude and phase spectra were measured and analyzed in dependence on the wavelength of excitation optical beam. In the ...
A consideration of transparent metal structures for subwavelength diffraction management
(Institute of Electrical and Electronics Engineers Inc., 2006)
We considered theoretically and experimentally one-dimensional multilayered metallodielectric nanofilms with nanometric thickness for imaging below the diffraction limit. We investigated their behavior in the ultravioled ...
Ambient-temperature operation of nonequilibrium magnetoconcentration infrared detectors in InSb and HgCdTe
(IEEE Computer Society, 2002)
We present a theoretical and experimental consideration of magnetoconcentration-based long-wavelength infrared photodetectors with nonequilibrium Auger-process suppression, designed for room-temperature operation. Our ...
