Biquaternionic representations of angular momentum and Dirac equation
(Slovak Acad Sciences Inst Physics, 2003)
In the present article, after defining biquaternions, the general properties of biquaternion's algebra are introduced. The matrix representations of biquaternions are presented, as well. Then, the biquaternionic angular ...
The quaternionic energy conservation equation for acoustic
(Slovak Acad Sciences Inst Physics, 2003)
After introducing the quaternions and its algebra, the equations of the linear acoustics are defined. The local conservation equation for energy of the linear acoustics using quaternions and a quaternionic first-order ...
Dual quaternionic reformulation of electromagnetism
(Slovak Acad Sciences Inst Physics, 2003)
It can be said that Maxwell's equations are one of the well-known equations of Physics. Despite the fact that this equations are more than hundred years old (1865), they still are the cornerstone of electrodynamics. Although ...
Electrochemical preparation of poly(2-bromoaniline) and poly(aniline-co-2-bromoaniline) in acetonitrile
(John Wiley & Sons Inc, 2003)
Electrochemical preparation of poly(2-bromoaniline) (PBrANI) and poly(aniline-co-2-bromoaniline) [P(An-co-2-BrAn)] was carried out in an acetonitrile solution containing tetrabutylammonium perchlorate (TBAP) and perchloric ...
Removal of heavy metal ions using the fungus Penicillium canescens
(Multi Science Publ Co LTD, 2003)
The potential use of the fungus Penicillium canescens for the removal of cadmium, lead, mercury and arsenic ions from aqueous solutions was evaluated in this study. Equilibrium biosorption of the heavy metal ions was ...
Biosorption of cadmium, lead, mercury, and arsenic ions by the fungus Penicillium purpurogenum
(Marcel Dekker Inc, 2003)
The potential use of the fungus Penicillium purpurogenum to remove cadmium, lead, mercury, and arsenic ions from aqueous solutions was evaluated. Biosorption of heavy metal ions reached equilibrium in 4 h. Heavy metal ions ...
Electrochemical preparation of soluble sulfonated polymers and aniline copolymers of aniline sulfonic acids in dimethylsulfoxide
(John Wiley & Sons Inc, 2003)
Fully sulfonated polyaniline was produced during the electrochemical polymerization of orthanilic, metanilic, and sulfanilic acids in dimethylsulfoxicle (DMSO). The dry conductivity values of the polymers obtained from the ...
Novel methacryloylamidophenylalanine functionalized porous chelating beads for adsorption of heavy metal ions
(John Wiley & Sons Inc, 2003)
The purpose of this study was to investigate in detail the adsorption performance of poly(2-hydroxyethylmethacrylate-methacryloylamidophenylalanine) [p(HEMA-MAPA)] beads. The metal-complexing comonomer MAPA was synthesized ...
Preconcentration of copper on ion-selective imprinted polymer microbeads
(Elsevier Science BV, 2003)
Molecular recognition-based separation techniques have received much attention in various fields because of their high selectivity for target molecules. Molecular imprinting has been recognized as a promising technique for ...
Removal of aluminium by Alizarin Yellow-attached magnetic poly(2-hydroxyethyl methacrylate) beads
(Elsevier Science BV, 2003)
Since the discovery of the implication of aluminium in dialysis encephalopathy, much progress has been made in the preparation of dialysis water from which the metal is now virtually excluded. In this study, Alizarin ...
