Bio-membrane based on modified cellulose, lignin, and tannic acid for cation and oxyanion removal: Experimental and theoretical study
(Process Safety and Environmental Protection, 2021)
Two optimized methods, based on epoxy-amino reactivity of the Cellulose fibres (Cell) modified with diethylenetriamine (Cell-DETA), (3-Glycidyloxypropyl)trimethoxysilane (Cell-Glymo), Lignin modified with epichlorohydrine ...
Surface characterization of macroporous glycidyl methacrylate based copolymers by inverse gas chromatography
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
Two samples of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate), PGME, with different porosity parameters were synthesized by suspension copolymerization and modified by ring-opening ...
Application of ANOVA method to precipitation behaviour studies
(Materials Science and Engineering A: Structural Materials Properties Microstructure and Processing, 2005)
The Analysis of variance (ANOVA) method has been used to illustrate the implementation of adaptive numerical (AN) techniques for the prediction of the precipitation behaviour of commercial materials. Case studies involving ...
Thermomechanical Properties and Cavitation Resistance of a High-Alumina Low-Cement Castable
(Wiley-Blackwell, Malden, 2011)
The purpose of this study was to investigate the mechanical properties and level of cavitation damage to alumina-based low-cement castable. The effects of temperature treatment on some of the mechanical properties (strength, ...
Photoreactive hyperbranched urethane acrylates modified with a branched saturated fatty acid
(Elsevier, Amsterdam, 2006)
Urethane acrylate resins based on partially modified aliphatic hyperbranched polyesters (HBP) were synthesized. HBP of the second and the third pseudo-generation were synthesized from 2,2-bis(hydroxymethyl)propionic acid ...
Dielectric investigation of some woven fabrics
(Amer Inst Physics, Melville, 2009)
In this paper, we have investigated the temperature dependence of dielectric properties (relative dielectric permeabilities and dielectric tangents of losses) for woven fabrics of hemp, jute, flax, cotton, polyester (PES), ...
Thermal shock damage characterization of refractory composites
(Elsevier Sci Ltd, Oxford, 2008)
The possibility of using dolomite and bauxite for synthesis of high temperature castable was studied. Behavior of the material in conditions of rapid temperature changes was investigated. Water quench test was applied to ...
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 ...
