Investigations into the neurodegenerative mode of action of dihydroxytetrahydroquinoline derivatives.
(1997)
Preliminary testing of a dihydroxyguinoline derivative, 3-amino-6,7-dihydroxy-1,2,3,4-tetrahydroquinoline (6,7-ADTQ), showed substantial serotonergic depletion in mouse whole brain, but with only moderate selectivity. This ...
Part I. Kinetic studies of the complexation reactions of nickel(II) with hydroxamic acids in aqueous medium. Part II. Kinetic studies of the formation and dissociation reactions of ionomycin and 2,6-dimethylheptane-3,5-dione with nickel(II) and magnesium(II) in 80 percent methanol-water medium.
(1997)
The second part of the study involved the reactions of nickel(II) and magnesium(II), with the ionophore ionomycin and the model compound 2,6-dimethyl-3,5-heptanedione (DMHD). A detailed analysis of the kinetic data for ...
Characterization of pure and phase-stabilized sodium phosphate.
(1998)
This work illustrates the necessity of using a variety of techniques when characterizing these systems, which undergo complex structural changes that cannot be completely characterized using a single technique. The XRD ...
Investigations of the effects of iron, manganese, and nickel on the properties of sulfated zirconia catalysts.
(1997)
Thermogravimetry (TG) was utilized to study catalyst thermal stability and to measure sulfate contents for catalysts with differing compositions. Temperature programmed desorption (TPD) measurements of surface adsorbed ...
A study of the use of Kelex 100 for removal of cadmium using ligand-modified micellar-enhanced ultrafiltration.
(1999)
Ligand-modified micellar-enhanced ultrafiltration (LM-MEUF) is a membrane based separation method for removal of metal ions from aqueous solutions. An amphilic ligand which will selectively complex the target ion is ...
Complexation studies of 5,5'-dinitro BAPTA and Mag-quin-1, with the divalent cations of cadmium, lead, zinc, copper, nickel, and calcium.
(1999)
Log values for the first three stepwise, mixed-mode protonation constants of MQ1 are: log KH1 = 7.57 +/- 0.01, log KH2 = 3.73 +/- 0.01, and KH3 = 2.41 +/- 0.02 at I = 0.05 (TEAP). Log values for the 1:1 metal to MQ1 complex ...
Monomeric, dimeric, and polymeric cationic surfactants.
(1997)
Another subject of this work in chapter 4 is the binding of chromate anions by polymeric surfactants, namely polyethyleneimine (PEI), hexyl PEI and lauryl PEI. PEI, one of the most widely studied polyelectrolytes, is known ...
