Synthesis and characterization of spray pyrolysis Zinc Oxide microrods
(Elsevier Science Sa, 2007)
Zinc Oxide (ZnO) microrods were prepared by ultrasonic spray pyrolysis technique on glass substrates. The X-ray diffraction (XRD) patterns and scanning electron microscope images show that obtained rods are composed of ...
Martensitic transformation and magnetic properties of Fe-24.5%Ni-4.5%Si alloy
(Maney Publishing, 2007)
The effect of austenitising temperature and cooling rate on the morphology and magnetic properties of martensite in Fe-24-5%Ni-4-5%Si alloy has been studied by means of scanning electron microscopy, Mbssbauer spectroscopy ...
New calculation of excitation functions of proton-induced reactions in some medical isotopes of Cu, Zn and Ga
(Pergamon-Elsevier Science Ltd, 2007)
The new calculations on the excitation functions of Ni-61(p,n)Cu-61, Ni-62(p,n)Cu-62, Ni-64(p,n)Cu-64, Cu-61(p,2n)Zn-62, Cu-63(p,n)Zn-63, Cu-65(p,n)Zn-65, Zn-66(p,n)Ga-66, Zn-67(p,2n)Ga-66, Zn-67(p,n)Ga-67 and Zn-68(p,n)Ga-68 ...
Thermal properties and crystallinity of thermotropic liquid crystalline copolyesters prepared from poly(ethylene terephtalate) (PET) and rigid aromatic units
(Taylor & Francis Inc, 2007)
A series of copolyesters were synthesized by rnelt-polycondensation reaction of poly(ethylene terephtalate) (PET) with various proportions of equimolar compositions of p-acetoxybenzoic acid (p-ABA), hydroquinone diacetate ...
Single-step purification of recombinant Thermus aquaticus DNA polymerase using DNA-aptamer immobilized novel affinity magnetic beads
(Wiley, 2007)
A DNA aptamer specific for Thermus aquaticus DNA polymerase (Taq-polymerase) was immobilized on magnetic beads, which were prepared in the presented study. The effect of various parameters including pH, temperaturem and ...
Molecular dynamics simulation of melting behaviour of small gold clusters: Au-N (N=12-14)
(Iop Publishing Ltd, 2007)
We have investigated the melting behaviour of AuN (N = 12 - 14) clusters by means of molecular dynamics simulation on the basis of the Voter - Chen version of the embedded-atom method. The melting behaviour of the clusters ...
Investigation of the pairing effect using newly evaluated empirical studies for 14-15 MeV neutron reaction cross sections
(American Physical Soc, 2007)
The asymmetry term effects for the cross sections of (n, charged particle) and (n,2n) reactions at 14-15 MeV neutron incident energy have been investigated. The effects of pairing and odd-even nucleon numbers in new data ...
4-vinylpyridine and 2-hydroxyethylmethacrylate monomer mixture graft copolymerization onto poly(ethylene terephthalate) fibers using benzoyl peroxide
(Springer, 2007)
Poly(ethylene terephthalate) (PET) fibers were grafted with 4-vinyl pyridine (4-VP) and 2-hydroxyethylmethacrylate (HEMA) using benzoyl peroxide (Bz(2)O(2)) as initiator in aqueous media. PET fibers were swelled in ...

(Amer Chemical Soc, 2007)
The reactions of hexachlorocyclotriphosphazatriene, N3P3Cl6, with N/O donor-type N-alkyl-o-hydroxybenzyl- and o-hydroxynaphthylamines result in novel mono-(3a, 4a and 4b), di- (5a and 5b), and tri- (3b, 6a, and 6b) spirocyclic ...
Removal of Cd(II), Hg(II), and MID ions from aqueous solution using p(HEMA/Chitosan) membranes
(Wiley, 2007)
An interpenetration network (IPN) was synthesized from 2-hydroxyethyl methacrylate (HEMA) and chitosan, p(HEMA/chitosan) via UV-initiated photo-polymerization. The selectivity to different heavy metal ions viz Cd(II), ...
