Metabolism of L-α-arginine in the biosynthesis of blasticidin S

Creator:: Woo, Nam-tae
Abstract:: Two labelled arginines, DL-[2,3,3,-²H₃]arginine, 8, and DL-[ ¹³C, 2-¹⁵N]arginine, 9, were synthesized. These were fed to cultures of Streptomyces griseochromogenes in order to probe the mechanism of the apparent arginine-2,3- aminomutase reaction occurring in biosynthesis of blasticidin S, 1. In previous studies of the enzymes lysine-2,3- aminomutase and tyrosine-2,3-aminomutase different...

Fundamental Studies of the Structure-Property Correlations of Na-ion and K-ion Storage in Non-Graphitic Carbon

Creator:: Li, Zhifei
Abstract:: Grid-scale energy storage systems are urgently needed to increase the flexibility and rigidity of the grid for modern society and take full advantage of the renewable green energy resources such as solar energy and wind energy. Na-ion batteries (NIBs) and K-ion batteries (KIBs) have been emerged as one of the...

Precursor Chemistry and Film Structure and Properties via Solution Deposition

Creator:: Huang, Yu
Abstract:: Chemistry of preparing dense film from solution deposition is explored with several cases in this thesis. Surface dense structure, conversion at melting point, and ion exchange in aqueous solution are the main topics covered here for the thin films of aluminum oxide phosphate and tin dioxide. Thin film density, optical...

Unlocking Water's Potential for Energy Storage: Abundant Materials for a Ubiquitous Problem

Creator:: Leonard, Daniel P.
Abstract:: Water is an absolute necessity for life as we know it. It provides a useful medium in which chemical reactions take place that allowed for the development of single cellular organisms. When combined with the evolutionary accident that was pho- tosynthesis, water became not only a useful medium chemical reactions,...

Structure-Property Relationships of Disordered Electronic Materials : From Crystalline to Amorphous

Creator:: Surta, Todd Wesley, Jr.
Abstract:: Two perovskite materials (Bi0.5(A)0.5)(Sc0.5Nb0.5)O3, where A = K+ and Na+ were synthesized phase pure for the first time. Their structures were determined by indexing synchrotron X-ray diffraction data and subsequent combined Rietveld refinement on neutron and synchrotron X-ray diffraction data revealing significant disorder on the A-sites of these materials. A...

Organic Crystalline Solids : Investigating their Capability, Storage Mechanism and Structural Evolution in Dual-Ion Batteries

Creator:: Rodríguez Pérez, Ismael A.
Abstract:: Widespread installation of renewable energy sources, such as wind and solar, has been delayed by the lack of suitable stationary energy storage solutions. Current large-scale technologies, such as pumped hydro and compressed air, are geographically restricted. This is where electrochemical energy storage - batteries or hybrid capacitors can play a...

Preparation and Properties of Porous Carbon Materials

Creator:: Xing, Zhenyu
Abstract:: Porous carbon is indispensable in modern technology applications. It is used for energy storage, gas separation, water purification, catalyst support, and chromatography. The diversity of its applications stems from its unique properties, including high specific surface area, tunable pore volume, and chemical stability. Specifically, the large surface area provides high...

Biosynthesis of blasticidin S : mechanistic and stereochemical investigations

Creator:: Prabhakaran, P. C.
Abstract:: Feeding of [3-¹³C, 2-¹⁵N]arginine, 38a, unequivocally established that the β- arginine moiety of blasticidin S, 1, was formed from α-arginine by an intramolecular migration of the α-amino group to the β- position. Further feedings using chirally deuteriated arginines 38e and 38f revealed that the aminomutase process occurred with inversion of...

Reaction Pathways of Oxo-Hydroxo Group 5 Clusters to Metal Oxide Thin Films

Creator:: Mansergh, Ryan H.
Abstract:: Oxo-hydroxo Group 5 metal clusters are an untapped resource to study and advance aqueous solution processing of metal oxide thin films. The tetramethylammonium (TMA) hexatantalate salt (TMA6[H2Ta6O19]) yields dense Ta2O5 films (~95% of the bulk ß-Ta2O5 density) with atomically smooth surfaces (<4 Å root mean square surface roughness). This same...

Synthesis, characterization, and structural modeling of graphite intercalation compounds with fluoroanions

Creator:: Yan, Wei
Abstract:: New synthetic strategies have been investigated for nano-dimensioned graphite particles or even isolated graphene sheets. One approach is to prepare graphite intercalation compounds (GICs) with low layer charge density and appropriate gallery height, followed by the colloidal dispersion or exfoliation of the resulting GICs. A series of anions has been...
