Characterization of electrochemically synthesized PANI on graphite electrode for potential use in electrochemical power sources
(Elsevier Science Sa, Lausanne, 2009)
Polyaniline (PANI) on graphite electrode was synthesized electrochemically under galvanostatic condition at current density of 2.0 mA cm(-2) from aqueous solution of 1.0 mol dm(-3) HCl and 0.25 mol dm(-3) aniline monomer. ...
Hindered, 1,1-disubstituted monomers. Chain transfer to benzene in the radical polymerisation of di-n-butylitaconate
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The transfer constant to benzene in the radical polymerisation of di-n-butyl itaconate, DBI, was measured at 60 degrees C and found to have the value of 2.2 x 10(-3). This value is surprisingly high considering that benzene ...
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 ...
Solvent effects on the structure-property relationship of anticonvulsant hydantoin derivatives: A solvatochromic analysis
(Biomed Central Ltd, London, 2011)
Considering the pharmaceutical importance of hydantoins, a set of 25 derivatives of phenytoin, nirvanol and 5-methyl-5-phenylhydantoin, the lipophilicities of which were gradually increased by the introduction of different ...
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 ...
Fast estimation of quasi-steady states of cyclic nonlinear processes based on higher-order frequency response functions. Case study: Cyclic operation of an adsorption column
(Amer Chemical Soc, Washington, 2006)
A new method for fast approximate calculation of quasi-steady states of cyclic processes is presented. The method is based on the concept of higher-order frequency response functions. The system input is represented in the ...
Microbial Polysaccharides and their Derivatives as Current and Prospective Pharmaceuticals
(Bentham Science Publ Ltd, Sharjah, 2008)
The ability to produce polysaccharides is widely found among microbial species. The structural diversity of the microbial polysaccharides (MPS) leads to a wide diversity of their applications. This review focuses pharmacological ...
Influence of aerosol formation mechanism by an ultrasonic field on particle size distribution of ceramic powders
(Elsevier Science Bv, Amsterdam, 1999)
Aerosol droplet genesis by ultrasonic atomization has been theoretically studied using a model for three-dimensional spherical/ellipsoidal waves generated by excitation of a system of given geometry by forced frequency of ...
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 ...
