Use of methacrylic acid grafted poly(ethylene terephthalate) fibers for the removal of basic dyes from aqueous solutions
(John Wiley & Sons Inc, 2008)
A reactive fibrous adsorbent was prepared through the grafting of a methacrylic acid monomer Onto poly(ethylene terephthalate) fibers for the removal of basic dyes such as methylene blue and basic red 9 from aqueous solutions ...
A fixed point theorem for multi-maps satisfying an implicit relation on metric spaces
(Univ Belgrade, Fac Electrical Engineering, 2008)
We present a fixed point theorem for multi-valued mapping satisfying an implicit relation on metric spaces.
A fixed fuzzy point for fuzzy mappings in complete metric spaces
(Univ Osijek, Dept Mathematics, 2008)
In this paper we prove a fixed point theorem for fuzzy mappings over a complete metric space.
Position vectors of a timelike and a null helix in Minkowski 3-space
(Pergamon-Elsevier Science Ltd, 2008)
In this paper, we study the position vectors of a timelike and a null helix (or a W-curve), i.e. curve with constant curvatures in the Minkowski 3-space E-1(3). We give some characterizations for timelike and null helix ...
The effects of zinc nitrate, zinc acetate and zinc chloride precursors on investigation of structural and optical properties of ZnO thin films
(Elsevier Science Sa, 2008)
ZnO thin films were prepared using zinc chloride, zinc acetate and zinc nitrate precursors by spray pyrolysis technique oil glass substrates at 550 degrees C. Structural and optical properties of ZnO films were investigated ...
Effect of cooling conditions on the magnetic properties of bainite transformation in an Fe-2%Mn-0.5%Cr alloy
(Elsevier Science Bv, 2008)
The effect of cooling conditions on the magnetic properties of bainitic reaction in Fe-2%Mn-0.5%Cr alloy have been investigated using Mossbauer spectroscopy. Results showed that the bainite phase is magnetically ordered ...
Raman and TEM studies of Ge nanocrystal formation in SiOx: Ge/SiOx multilayers
(Wiley-V C H Verlag Gmbh, 2007)
Alternating germanosilicate-siliconoxide layers of 10-30 nm thickness were grown on Si substrates by plasma enhanced chemically vapor deposition (PECVD). The compositions of the grown films were determined by X-ray ...
Chitosan-grafted poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) membranes for reversible enzyme immobilization
(Wiley, 2007)
Epoxy group-contain g poly(hydroxyethyl methacrylate/glycidyl methacrylate), p(HEMA/GMA), membrane was prepared by UV initiated photopolymerization. The membrane was grafted with chitosan (CH) and some of them were chelated ...
Structure and Energetic of Bn (n = 2–12) Clusters: Electronic Structure Calculations
(Wiley, 2007)
The electronic and geometric structures, total and binding energies, first and second energy differences, harmonic frequencies, point symmetries, and highest occupied molecular orbital-lowest unoccupied molecular orbital ...
