Modeling Noise and Stability of Affinity-Based MEMS, NEMS and NOEMS Sensors of Ternary Gas Mixtures
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
We address noise and stability of adsorptionbased sensing of ternary gas mixtures in affinity-based MEMS, NEMS and NOEMS sensors. We investigate mechanisms of such chemical sensing in diverse industrial environments where ...
Organobentonite as efficient textile dye sorbent
(Wiley-V C H Verlag Gmbh, Weinheim, 2008)
Domestic bentonite clay was modified using cationic surfactant - hexadecyltrimethylammonium bromide (HDTMA-bromide) in order to obtain more efficient sorbent. Removal of Acid Orange 10 from aqueous solution at different ...
The influence of modification on structural, textural and adsorption properties of bentonite / Uticaj modifikacije na strukturna, teksturalna i adsorpciona svojstva bentonita
(Assoc Chemical Engineers Serbia, Belgrade, 2008)
Natural bentonite clay from the Bogovina locality in Serbia was Na-exchanged and modified using hexadecyll-trimethylammonium bromide as surfactant and organobentonite was obtained. The influence of modifications on the ...
Grand Canonical Monte Carlo study of argon adsorption in aluminium nanopores
(Taylor & Francis Ltd, Abingdon, 2011)
We present a theoretical study of argon adsorption on a model aluminium substrate structured with cylindrical nanopores. We employ state-of-the-art computational methods to obtain (i) accurate three-dimensional adsorption ...
Monolayer gas adsorption in plasmonic sensors: Comparative analysis of kinetic models
(Maik Nauka/Interperiodica/Springer, New York, 2013)
The analysis of adsorption kinetics is given, assuming no dissociative adsorption takes place and no multiple binding sites exist. The phenomenological nonlinear model and the simple linear model are considered from the ...
Sinteza, karakterizacija i sorpciona svojstva bentonita modifikovanih tetraalkilamonijum jonima / Synthesis, characterization and sorption properties of bentonite modified by tetraalkylammonium ions
(Универзитет у Београду, Хемијски факултет, 2010)
Ovaj rad je posvećen sintezi organobentonita (OB) dobijenih modifikacijom kvaternernim alkilamonijum katjonima (KAAK), karakterizaciji dobijenih uzoraka, ispitivanju njihovih adsorpcionih svojstava prema organskim i ...
Applications of bentonite in the environmental protection
(Society of Physical Chemists of Serbia, 2012)
Smectite rich clay from Bogovina, Serbia, was submitted to pillaring and organomodification. Pillared and organomodified materials were characterized using XRD, ICP-OES and N2 physisorption methods. The obtained pillared ...
Chitosan-montmorillonite bionanocomposite as textile dyes adsorbent
(Serbian Ceramic Society, 2016)
The removal of color dyes from wastewater before they are released in natural waters is important
since some dyes are highly toxic for environment. Although several traditional chemical and
biological processes exist for ...
Modelling of plasmonic biosensor temporal response influenced by competitive adsorption and analyte depletion
(IOP Publishing, 2021)
Highly sensitive detection of biological analytes by plasmonic sensors is based on analyte adsorption, which modifies the effective refractive index (RI) at the medium-sensor interface. The main issue with such sensors is ...
Nanostructured organic-inorganic hybrid smectite based composites
(Society of Physical Chemists of Serbia, 2018)
This paper represents a survey of the investigation conducted in the Center
for Catalysis and Chemical Engineering of the Institute of Chemistry,
Technology and Metallurgy, Belgrade, during last decade regarding
nanostructured ...
