3,9-dimethyl-1,11-diphenyl-4,8-diaza-undecane-1,11-dione dihydrate
(Munksgaard Int Publ Ltd, 1999)
The title compound, C23H26N2O2. 2H(2)O, displays strong intramolecular N-H ... O [2.637(2) Angstrom] and intermolecular O-H ... O [2.763(4) and 2.842(3) Angstrom] hydrogen bonds within each salicylideneimine unit and water ...
Polymorphism of M factors in populations of the housefly, Musca domestica L., in Turkey
(Cambridge Univ Press, 2000)
M factors, which determine maleness in Musca domestica, were found on the second, third, fourth and fifth linkage groups in housefly populations of Turkey. As in European populations, the male-determining factor was more ...
Functionalization of low molecular weight atactic polypropylene - Part II. Thermal and molecular weight studies
(Springer, 2000)
Number average molecular weight (M-n), intrinsic viscosity ([eta]) and glass transition temperature (T-g) of low molecular weight atactic polypropylene (APP) grafted with 4-allyl-1,2-dimethoxybenzene (DMAB), 4-allyl-2-me ...
Intramolecular hydrogen bonding and tautomerism in Schiff bases. Part II. Structures of 1-[N-(2-pyridyl)aminomethylidene}-2(1H)-naphtalenone (1) and bis[2-hydroxy-κO–N-(2-pyridyl)-1-naphthaldiminato-κN]zinc(II) (2)
(Elsevier Science Bv, 2000)
The Schiff base ligand (1) and its Zn(II) complex (2) have been synthesized and their crystal structures have been determined. Compound (1) crystallizes in the monoclinic space group C2/c with a = 26.993(2), b = 5.891(1), ...
Adsorption of heavy metal ions onto ethylene diamine-derived and Cibacron Blue F3GA-incorporated microporous poly(2-hydroxyethyl methacrylate) membranes
(Elsevier Science Bv, 2000)
Microporous poly( 2-hydroxyethylmethacrylate) (PHEMA) membranes carrying ethylene diamine (EDA) and Cibacron Blue F3GA were prepared for the removal of heavy metal ions (i.e. mercury, copper, lead and cadmium) from aqueous ...
Structures of four- and six-coordinate monomers of [N,N '-bis(5-chlorosalicylidene)-1,3-diaminopropane]nickel(II)
(Kluwer Academic/Plenum Publ, 2000)
[N,N' -Bis(5-chlorosalicylidene) -1,3 -diaminopropane] nickel(II) [Ni(C17H14N2O2Cl2)] 1 and [N,N' -Bis(5-chlorosalicylidene)-1,3 -diaminopropane] nickel(II) dihydrate [Ni(C17H14N2O2Cl2).2(H2O)] 2 were synthesized, and their ...
Removal of heavy metal ions from aquatic solutions by membrane chromatography
(Elsevier Science Bv, 2000)
Polyvinylalcohol membranes were prepared by a solvent casting technique. Metal-complexation ligand, i.e. monochlorotriazinyl-dye Cibacron Blue F3GA was then attached. These membranes with a high water content of 119%, and ...
In vitro cadmium removal from human serum by Cibacron Blue F3GA-thionein-complex conjugated affinity membranes
(John Wiley & Sons Ltd, 2000)
A new membrane affinity biosorbent carrying thionein has been developed for selective removal of cadmium ions from human serum. Microporous poly(2-hydroxyethyl methacrylate) (pHEMA) membranes were prepared by photopolymerization ...
Immobilization of glucoamylase onto spacer-arm attached magnetic poly(methylmethacrylate) microspheres: characterization and application to a continuous flow reactor
(Elsevier Science Bv, 2000)
Magnetic poly(methylmethacrylate) microspheres (MPMMA) were prepared by the solvent evaporation method and a 6-carbon spacer-arm (i.e. hexamethylene diamine, HMDA) was covalently attached by the reaction of carbonyl groups ...
