(Texas A&M University, 2007-04-25)This dissertation investigates three topics in the field of multiple-bonded metal chemistry. The first topic concerns the synthetic and theoretical considerations of ditungsten formamidinates and guanidinates compounds. ...
-
(2013-11-27)Transition metals play essential roles in biological systems, but Fe can also be toxic to cells. In order to maintain this balance between necessity and toxicity mechanisms are employed for regulating and storing intracellular ...

(2009-05-15)Phosphotriesterase (PTE) from Pseudomonas diminuta is a zinc metalloenzyme found in soil bacteria capable of organophosphate hydrolysis at rates approaching the diffusion controlled limit. Interest in PTE for degradation ...
-
(2009-06-02)An exogenous contrast agent has been developed to enhance the contrast achievable in Thermoacoustic Tomography (TAT). TAT utilizes the penetration depth of microwave energy while producing high resolution images through ...
-
(2011-02-22)Tyrosine Hydroxylase (TyrH) is a pterin-dependent mononuclear non-heme iron oxygenase. TyrH catalyzes the hydroxylation reaction of tyrosine to dihydroxyphenylalanine (DOPA). This reaction is the first and the rate-limiting ...
