Zinc ion-promoted adsorption of lysozyme to Cibacron Blue F3GA-attached microporous polyamide hollow-fiber membranes
(Elsevier Science BV, 2001)
Dye-affinity and metal chelate affinity adsorption are increasingly used for protein separation. Synthetic hollow fiber membranes have advantages as support matrices in comparison to conventional bead supports because they ...
Spectroscopic determination of acid dissociation constants of some pyridyl Shiff bases
(American Chemical Society, 2006)
The acid dissociation constants (pK(a)) of eight biologically active pyridyl Shiff bases were determined using a UV-vis spectroscopic technique at 25 +/- 0.1 degrees C. The first acidity constants (pK(a1)) of the ...
Synthesis, spectral studies of salicylidine-pyridines: Crystal and molecular structure of 2-[(1E)-2-aza-2-(5-methyl (2-pyridyl)ethenyl)]-4-bromobenzen-1-ol
(Pergamon-Elsevier Science LTD, 2007)
Schiff bases derived from different meta-substituted salicylaldehyde and 5-methylaminopyridine have been synthesized and characterized by elemental analysis, FT-IR, NMR and UV-vis techniques. NMR assignments were made using ...
alpha-In2S3 and beta-In2S3 phases produced by SILAR technique
(Taylor & Francis LTD, 2012)
In2S3 films have been deposited by the successive ionic adsorption and reaction technique (SILAR) at room temperature. The films have been examined to evaluate the structural and optical properties. X-ray diffraction spectra ...
In situ photoproduction of dichlorodibenzo-p-dioxin from non-ionic triclosan isolated in solid argon
(Elsevier Science BV, 2012)
The infrared spectrum of triclosan [or 5-chloro-2-(2,4-dichlorophenoxy)phenol] isolated in a low temperature (similar to 15 K) argon matrix has been recorded and assigned with help of DFT claculations undertaken with the ...
Validated capillary electrophoresis study for the determination of cetirizine in pharmaceutical forms
(Taylor & Francis Inc, 2006)
A capillary electrophoretic method for the determination of cetirizine is described in this study. The method was developed by using a running buffer consisting of 10 mM of 10% methanol with pH 8.5, employing a fused silica ...
Preparation and characterization of activated carbon produced from pomegranate seeds by ZnCl2 activation
(Elsevier Science BV, 2009)
In this study, pomegranate seeds, a by-product of fruit juice industry, were used as precursor for the preparation of activated carbon by chemical activation with ZnCl2. The influence of process variables such as the ...
Vibrational spectroscopic study on some Hofmann type clathrates: M(1-Phenylpiperazine)(2)Ni(CN)(4)center dot 2G (M = Ni, Co and Cd; G = aniline)
(Elsevier Science BV, 2009)
New Hofmann type aniline clathrates in the form of M(PP)(2)Ni(CN)(4)center dot 2G (where pp = 1-phenylpiperazine, G = aniline and M = Ni. Co and Cd) have been prepared in powder form and FT-IR and Raman spectra have been ...
Effect of channel thickness on the field effect mobility of ZnO-TFT fabricated by sol gel process
(Elsevier Science Sa, 2015)
In this study, bottom-gate structured ZnO TFTs were fabricated on pSi/SiO2 substrate. ZnO active layers with different thickness were deposited by using sol gel spin coating method and the electrical performances of the ...
Schiff bases as corrosion inhibitor for aluminium in HCl solution
(Pergamon-Elsevier Science LTD, 2012)
Three Schiff bases named 1,5-bis[2-(2-hydroxybenzylideneamino)phenoxy]-3-oxopentane (D1), 1,5-bis[2-(5-chloro-2-hydroxybenzylideneamino)phenoxy]-3-oxopentane (D2) and 1,5-bis[2-(5-bromo-2-hydroxybenzylideneamino)phenoxy] ...
