Model complexes for active sites of diiron metalloproteins, dioxygen reactivity and water effects
(Massachusetts Institute of Technology, 2004)
(cont.) tetrairon(II) cubane complex was identified and structurally characterized. Chapter 4: Synthesis and Characterization of [Fe₂...CR)]³⁺ and [Fe₂...CR)]³⁺ Complexes with Carboxylate-Rich Metal Coordination Environment ...
Mechanism of the efficient quenching of tryptophan fluorescence in human gamma crystallin
(Massachusetts Institute of Technology, 2008)
Quenching of the fluorescence of buried tryptophans (Trps) is an important reporter of protein conformation. Human [gamma]D-crystallin (H[gamma]D-Crys) and human [gamma]S-crystallin (H[gamma]S-Crys) are both very stable ...
Synthesis, structure, and magnetic properties of spin-1/2 kagomé antiferromagnets
(Massachusetts Institute of Technology, 2008)
Stoichiometrically pure S = 1/2 Cu2+ kagomé materials have been synthesized. Such materials provide an ideal venue for exploration of quantum states on a kagomé because they exhibit strong geometric spin frustration and ...
Hydrogen bond rearrangements and the motion of charge defects in water viewed using multidimensional ultrafast infrared spectroscopy
(Massachusetts Institute of Technology, 2010)
Compared with other molecular liquids, water is highly structured due to its ability to form up to four hydrogen bonds to its nearest neighbors, resulting in a tetrahedral network of molecules. However, this network is ...
Studies of biologically relevant iron-oxygen chemistry
(Massachusetts Institute of Technology, 1988)
Novel II-IV semiconductor nanocrystal gain media : from amplified spontaneous emission to lasing
(Massachusetts Institute of Technology, 2002)
This thesis details efforts in using cadmium selenide (CdSe) nanocrystallites (NCs) as a novel lasing media. We begin with the synthesis of polymer/NC composites, in which the NCs are stabilized within a long-chain ...
Hydrogen bonding in aqueous solution and peptide helicity studied using model systems
(Massachusetts Institute of Technology, 1999)
