Catalytic cracking of poly(ethylene) and poly(styrene) by silica-alumina, HZSM-5 zeolite and sulfated zirconia.
(1997)
The catalytic cracking mechanisms of poly(ethylene) and poly(styrene) differ considerably from their thermal cracking mechanisms. In the case of poly(ethylene), thermal cracking leads to the formation of a wide range of ...
Copper catalyzed cyclopropanation using chiral [2.2]paracyclophane ligands and activation of naphthalenes toward catalytic hydrogenation by coordination of metal moieties.
(1999)
The coordination of an iron cyclopentadienyl cation to the naphthalene moiety resulted in activation of the naphthalene ligand toward catalytic hydrogenation. Napthalene, and several dimethylnaphthalenes, when coordinated ...
Surfactant-cycladextrin binding, mixed surfactant micelles, and new surface tension methods.
(1998)
A stainless steel rod with precisely known radius is used to measure surface tensions. One of the most important aspects in two new methods is that a top-loading analytical laboratory balance of 0.1 to 1 mg precision can ...
Sequence and analysis of cancer-related genes from three genomic regions; 9p21, 9p22, and 3q26.
(1998)
The regulatory regions of af9, p16INK4a, and p15INK4b were investigated in depth using computer algorithms designed to predict the locations of promoters and upstream transcription factor binding sites in DNA sequence. The ...
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 ...
Titanocene-catalyzed stereoselective couplings of aldehydes.
(1999)
A catalytic pinacol reaction that was enantioselective was also of interest. Three chiral titanium complexes possessed tethers: Brintzinger's catalyst or ethylenebis-(4,5,6,7-tetrahydroindenyl) titanium dichloride 1, (1S, ...
Conformational dynamics and structure of FepA, a ligand-gated channel in the bacterial outer membrane.
(1998)
Since Waring & Werkman documented a microbial requirement for iron in 1944, much progress has been made in understanding how microbes assimilate this mundane but biological precious metal. The proteins involved in iron ...
Nitrosyl and nitroso complexes of group 8 metalloporphyrins.
(1998)
Chapter 3 of this dissertation describes the synthesis and characterization of osmium nitrosyl porphyrins containing organo, chloro and $\mu$-oxo ligands and the extensions of the synthetic methodology to the preparation ...
Investigation into the in vivo metabolism of glutathionyl conjugates of dopamine and norepinephrine: Possible insights into neurodegenerative diseases.
(1997)
The in vitro and in vivo hydrolyses of 5-S-Glu-NE were investigated in rat brain homogenates and by intracerebroventricular (icv) administration in rat brains. Under in vitro conditions, 5-S-Glu-NE was hydrolyzed to give ...
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 ...
