Hamilton formulation for the analysis of RLC circuits
(Physics Essays Publication, 2002)
The Hamiltonian formulation well known in classical mechanics is applied to RLC circuits. The flux linkages for the inductances are assumed to be the generalized momenta (conjugate momenta), and the Hamiltonian function ...
Preparation and characterization of the newly synthesized metal-complexing-ligand N-methacryloylhistidine having PHEMA beads for heavy metal removal from aqueous solutions
(Wiley-V C H Verlag GMBH, 2002)
The aim of this study was to investigate in detail the performance for removal of heavy metal ions of beads composed of poly(2-hydroxyethyl methacrylate) (pHEMA) to which N-methacryloyhistidine (MAH) was copolymerized. The ...
Electropolymerization and in situ sulfonation of aniline in water-acetonitrile mixture containing FSO3H
(Elsevier Science Sa, 2002)
In situ sulfonation reaction of aniline was carried out in water and water-acetonitrile mixture by changing both aniline and fluorosulfonic acid (FSO3H) concentrations. The optimum conditions for the polymer formation was ...
Poly(hydroxyethyl methacrylate-co-methacrylamidoalanine) membranes and their utilization as metal-chelate affinity adsorbents for lysozyme adsorption
(Vsp BV, 2002)
Different adsorbents have been reported in the literature for protein purification. The authors have developed a novel and new approach to obtain high protein adsorption capacity utilizing a 2-methacrylamidoalanine-containing ...
Preparation of poly(hydroxyethyl methacrylate-co-methacrylamidohistidine) beads and its design as a affinity adsorbent for Cu(II) removal from aqueous solutions
(Elsevier Science BV, 2002)
Different metal-complexing ligands carrying synthetic adsorbents have been reported in the literature for heavy metal removal. We have developed a novel and new approach to obtain high metal adsorption capacity utilizing ...
Preparation of cibacron blue F3GA-attached polyamide hollow fibers for heavy metal removal
(John Wiley & Sons Inc, 2002)
Dye-affinity adsorption has been used increasingly for heavy metal removal. Synthetic hollow fibers have advantages as support matrices in comparison to conventional bead supports because they are not compressible and they ...
Electrochemical copolymerization of aniline and anilinesulfonic acids in FSO3H/acetonitrile solution
(John Wiley & Sons Inc, 2002)
The effects of 2-aminobenzenesulfonic acid (orthanilic acid), 3-aminobenzenesulfonic acid (metanilic acid), and 4-aminobenzenesulfonic acid (sulfanilic acid) on the electropreparation and properties of polyaniline (PANI) ...
Quantum chemical studies on some 1,2,4-triarylsubstituted imidazoles
(Elsevier Science BV, 2002)
The geometries, proton affinities and thermodynamic properties of some 1,2,4-triarylsubstituted imidazole derivatives were calculated with full geometry optimization using AM1 and PM3 methods in aqueous phase. A possible ...
Investigation of acid-base behaviour of some 2-pyridylbenzimidazoles using semi-empirical methods
(Elsevier Science BV, 2002)
Acid-base behaviour of some 2-(n'-pyridyl) benzimidazoles (n' = 2,3,4) have been studied in order to search the protonation site and to predict pK(a) values of these molecules both in gas and aqueous phases using semi-empirical ...
Heavy metal ion adsorption properties of methacrylamidocysteine-containing porous poly(hydroxyethyl methacrylate) chelating beads
(Multi Science Publ Co LTD, 2002)
Details of the adsorption performance of poly(2-hydroxyethylmethacrylate-methacrylamidocysteine) [p(HEMA-MAC)] beads towards the removal of heavy metal ions from aqueous solution were studied. The metal-complexing ligand ...
