Flow regimes and liquid mixing in a draft tube gas-liquid-solid fluidized bed
(Pergamon-Elsevier Science Ltd, Oxford, 1992)
Flow behavior of gas bubbles, liquid and particles, and mixing in the liquid phase were studied in draft and annulus of a draft tube gas-liquid-solid fluidized bed. The experimental unit was a 80mm ID × 1.5 m column with ...
Synthesis and rheological study of some maleic acid and fumaric acid stereoregular polyesters, 10 - Synthesis and characterization of alpha,omega-dihydroxyoligo(alkylene maleate)s
(Wiley-VCH Verlag Gmbh, Weinheim, 1998)
alpha,omega-Dihydroxyoligo(alkylene maleate)s with molecular weights ranging from 1500 to 4000 were prepared by polycondensation, in 1-methyl-2-pyrrolidone at 105 degrees C, of potassium maleate and 1,4-dibromobutane, ...
Silver-Loaded Cotton/Polyester Fabric Modified by Dielectric Barrier Discharge Treatment
(Wiley-VCH Verlag Gmbh, Weinheim, 2009)
The preparation of antimicrobial silver-loaded cotton/polyester fabrics has been carried out by DBD surface activation followed by silver sorption from aqueous silver nitrate solution. A series of DBD fabric treatments was ...
Electrothermal desorption in an annular-radial flow - ACFC adsorber - Mathematical modeling
(Springer, New York, 2005)
A mathematical model of an annular, radial-flow adsorber with the possibility of electroresistive heating of the adsorbent bed has been postulated. The model consists of a set of coupled nonlinear PDEs, ODEs and algebraic ...
The potentiostatic current transients and the role of local diffusion fields in formation of the 2D lead dendrites from the concentrated electrolyte
(Elsevier, 2015)
Electrodeposition of lead from the concentrated nitrate electrolyte in the potentiostatic regime of electrolysis has been investigated by the analysis of the potentiostatic current transients and scanning electron microscope ...
An inverse gas chromatography study of macroporous copolymers based on methyl and glycidyl methacrylate
(Elsevier, Amsterdam, 2000)
Adsorption properties of two laboratory synthesized macroporous copolymers based on methyl and glycidyl methacrylate were investigated by inverse gas chromatography. Retentions of 12 organic compounds were measured in the ...
Influence of synthesis parameters on the structure of boehmite sol particles
(Elsevier, Amsterdam, 2003)
Influence of the type and amount of acid, used for aluminium hydroxide peptization, on the crystallinity and specific surface area of the dispersed phase of boehmite sols as well as the pH of sols, was investigated. The ...
The thermal degradation of poly(ditetrahydrofurfuryl itaconate)
(Elsevier, Amsterdam, 2001)
The goal of this investigation was to study the thermal degradation of poly(ditetrahydro-furfuryl itaconate) (PDTHFI) by thermogravimetry (TG). The monomer was polymerized in bulk at 40 degreesC using AIBN as initiator. ...
Synthesis of Silica Particles Using Ultrasonic Spray Pyrolysis Method
(Metals, 2021)
Silica has sparked strong interest in hydrometallurgy, catalysis, the cement industry, and paper coating. The synthesis of silica particles was performed at 900 degrees C using the ultrasonic spray pyrolysis (USP) method. ...
Lead spatio-temporal pattern identification in urban microenvironments using moss bags and the Kohonen self-organizing maps
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
The first investigation of the use of the Kohonen self-organizing map (SOM) which includes lead concentration and its isotopic composition in moss bags to assess the spatial and temporal patterns of lead in the urban ...
