Tautomeric properties, conformations and structure of N-(2-hydroxy-5-chlorophenyl) salicylaldimine
(Elsevier Science Bv, 1999)
The crystal structure of N-(2-hydroxy-5-chlorophenyl) salicylaldimine (C13H10NO2Cl) was determined by X-ray analysis. It crystallizes orthorhombic space group P2(1)2(1)2(1) with a = 12.967(2) Angstrom, b = 14.438(3) Angstrom, ...
Biosorption of inorganic mercury and alkylmercury species on to Phanerochaete chrysosporium mycelium
(Elsevier Sci Ltd, 1999)
The biosorption of inorganic mercury (HgCl2), methyl mercury (CH3HgCl) and ethyl mercury (C2H5HgCl) onto the dry biomass of Phanerochaete chryosponum was studied from aqueous media which concentrations in the range of 5-500 ...
3,3-Dichloro-1-(p-chlorophenyl)4-(p-methoxyphenyl)-2-azetidinone
(Wiley-Blackwell, 1999)
The crystal structure of the title compound, C16H12Cl3NO2, has a nearly planar beta-lactam ring with the N atom out of the best plane by 0.032(2) Angstrom. The C-C bond distances in the beta-lactam ring are 1.544(4) and ...

Immobilization of catalase in poly(isopropylacrylamide-co-hydroxyethylmethacrylate) thermally reversible hydrogels
(John Wiley & Sons Ltd, 1999)
Catalase was entrapped in thermally reversible poly (isopropylacrylamide-co-hydroxyethyl-methacrylate) (pNIPAM/HEMA) copolymer hydrogels. The thermoresponsive hydrogels, in cylindIl-rical geometry, were prepared in an ...
Functionalization of low molecular weight atactic polypropylene - Part I. Spectroscopic studies
(Springer Verlag, 1999)
Low molecular weight atactic polypropylene (APP) was functionalized with 4-allyl-2-methoxyphenol (eugenol), 4-allyl-1,2-dimethoxybenzene (DMAB), 4-propenylanisole(trans-anethole), cis-2,4,5-trimethoxypropenylbenzene ...
Controlled release of aldicarb from lignin loaded ionotropic hydrogel microspheres
(Taylor & Francis Ltd, 1999)
Aldicarb loaded microspheres of carboxymethyl cellulose, CMC, of various compositions were prepared with the crosslinking action of AI(III). Into these microspheres, lignin was introduced as a filler to further regulate ...
Determination of Cu, Zn and Cd in water by FAAS after preconcentration by baker's yeast (Saccharomyces cerevisiae) immobilized on sepiolite
(Springer Verlag, 1999)
By using the adsorbent Saccharomyces cerevisine immobilized on sepiolite an adsorption-elution method was developed for the preconcentration of Cu, Zn, and Cd followed by flame atomic absorption spectrometry (FAAS). ...
