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 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 ...
A consideration of optical noise figures of adsorption-based nanophotonic sensors
(Institute of Electrical and Electronics Engineers Inc., 2008)
We consider some intrinsic noise mechanisms appearing in nanophotonic sensors based on plasmonic structures and surface plasmon-polaritons. We analyze the photonic Johnson-Nyquist fluctuations and the adsorption and ...
Surface Texture Parameters in Optimizing Magnetic Force Images
(Belgrade : Astronomical Observatory, 2008)
In this work, the optimizing conditions necessary for magnetic field gradient imaging using Atomic Force Microscopy (AFM) and Magnetic Force Microscopy (MFM) in a lift mode have been established. 55 nm thick Co thin film ...
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 ...
Preparation of silver(I) complexes with itaconic acid-based hydrogels for biomedical application
(Materials and Manufacturing Processes, 2009)
Silver(I) complexes based on itaconic acid hydrogel were prepared and characterized in order to examine the potential use of these materials. FTIR, AFM, in vitro fluid-uptake, metal sorption, and antibacterial activity ...
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 ...
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 ...
Determination of adsorption capacity under static conditions / Odredjivanje adsorpcionog kapaciteta u statičkim uslovima
(Beograd (Serbia): Udruzenje za tehnologiju vode i sanitarno inzenjerstvo, 2007)
The adsorption process are more and more frequently applied in water treatments. The choice of the adsorption medium depends on the adsorption capacity. The adsorption capacity in statical conditions should always preceeds ...
