Estimation of competitive adsorption isotherms based on nonlinear frequency response experiments using equimolar mixtures-numerical analysis for racemic mixtures
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The nonlinear frequency response method for estimation of competitive adsorption isotherms, based on analysis of the response of a chromatographic column to sinusoidal perturbation of the inlet concentration, was modified ...
Quantification of deformation response at cyclic compression of polymer fibrous systems
(Elsevier Science Bv, Amsterdam, 2014)
The difficulty in qualitative evaluation of deformation properties of polymer fibrous assemblies lies in the fact that these materials differ from materials such as wood, concrete, steel, etc., as a consequence of the ...
Hydrothermal carbonization of spent mushroom substrate: Physicochemical characterization, combustion behavior, kinetic and thermodynamic study
(Journal of Analytical and Applied Pyrolysis, 2021)
Hydrothermal carbonization (HTC) was employed for the conversion of the spent mushroom substrate (SMS) into a carbonaceous hydrochar. The effect of operating temperature (180, 200, 220, 240, and 260 ?C) on the physicochemical, ...
"Green Meets Green" - Sustainable solutions of imidazolium and phosphonium ionic liquids with poly(ethylene glycol): Solubility and phase behavior
(Elsevier Science Bv, Amsterdam, 2013)
Liquid-liquid and solid-liquid phase behaviors of the binary solutions of imidazolium [C(2)mim](+) or trihexyltetradecyl phosphonium [P-6,P-6,P-6,P-14](+) ionic liquids having triflate [OTf](-), bistriflamide [NTf2](-) or ...
Characterization of PCBs from computers and mobile phones, and the proposal of newly developed materials for substitution of gold, lead and arsenic
(Springer Heidelberg, Heidelberg, 2013)
In this paper, we have analyzed parts of printed circuit board (PCB) and liquid crystal display (LCD) screens of mobile phones and computers, quantitative and qualitative chemical compositions of individual components, and ...
Al-Cd Alloy Formation by Aluminum Underpotential Deposition from AlCl3+NaCl Melts on Cadmium Substrate
(Springer, New York, 2013)
Aluminum was incorporated into a polycrystalline cadmium electrode surface by underpotential deposition from equimolar AlCl3+ NaCl melt at 473 K, 523 K, and 573 K (200 A degrees C, 250 A degrees C, and 300 A degrees C). ...
Hydrodynamic modeling of downward gas-solids flow. Part I: Counter-current flow
(Elsevier, Amsterdam, 2014)
The one-dimensional model of accelerating turbulent downward counter-current gas-solids flow of coarse particles was formulated and experimentally verified by measuring the pressure distribution along the transport tube. ...
Polycrystalline (Y0.7Gd0.3)(2)O-3:Eu3+ ceramics fabricated by Spark Plasma Sintering: Densification and microstructure development
(Elsevier Sci Ltd, Oxford, 2014)
Using Spark Plasma Sintering it is possible to produce polycrystalline ceramics of very fine microstructure and good mechanical properties. This work presents the fabrication of such ceramics using Eu3+-doped (Y0.7Gd0.3)(2)O-3 ...
Particle characterization of polydisperse quartz filtration sand
(Elsevier Science Bv, Amsterdam, 2014)
In this paper, different methods for particle characterization were applied to 16 polydisperse fractions of quartz filtration sand obtained by sieving, with sieve diameters in the interval d(m) = 0359 to 2.415. For each ...
Mechanism of adsorption of Cu2+ and Zn2+ on the corn silk (Zea mays L.)
(Elsevier, Amsterdam, 2017)
In this study the novel biosorbent - raw corn silk (CS) was investigated for Cu2+ and Zn2+ removal from aqueous solutions. The physical and chemical properties of CS were determined by SEM - EDX and ATR - FTIR techniques. ...
