Geometric and Electronic Control of the Magnetic Properties of First-Row Transition Metal Complexes (2016-07-26)The realization that [Mn12(CH3COO)16(H2O)4O12]•2CH3COOH•2H2O (Mn12OAc) displayed magnetic hysteresis, a phenomenon usually associated with permanent bulk magnets, was a truly remarkable discovery since Mn12OAc is a ...
-
(Texas A&M University, 2004-09-30)Increasing attention has been given to the preparation and study of compounds with linear chains of metal atoms surrounded by four ligands. The majority of linear trimetal complexes are supported by dpa, the anion of ...
-
(2016-08-10)The critical need to miniaturize electronic devices has initiated a renaissance in the study of the electronic and magnetic properties of both discrete molecules and extended structures vis-à-vis their potential for ...
-
(2012-02-14)Ferric ferrocyanide (Prussian blue) and its analogues are renowned for the variety of properties and applications associated with them. At the same time, however, they suffer from issues related to their variable composition ...

(2021-04-05)Nanomaterials offer a unique platform to study the effect of morphology, light polarization, as well as quantum confinement on their photophysical properties. In this dissertation, two classes of nanomaterials – plasmonic ...
-
(2012-10-19)In all energy systems, the parameters necessary to calculate power are the same in functionality: an effort or force needed to create a movement in an object and a flow or rate at which the object moves. Therefore, the ...
-
(2011-02-22)The cyanide ligand has frequently been used to prepare clusters with novel magnetic properties due to its ability to provide an efficient pathway for superexchange between metal centers that are bound in an end-to-end ...
-
(2019-06-10)This research describes the synthesis and characterization of cyanometallate compounds based on 4d and 5d transition metal ions. Since the discovery of [Mnv12(CHv3COO)v16(H2O)v4Ov12] (Mnv12OAc) displaying magnetic hysteresis, ...
-
(2014-04-30)The versatile polyol/polyamine supporting ligand TDCI (1,3,5-tris(dimethylamino)- 1,3,5-trideoxy-cis-inositol was synthesized, and several lanthanide complex clusters of this ligand were produced.The coordination chemistry ...
-
(2013-05-01)This dissertation describes experimental studies of the structures and properties, and their correlations in ferromagnetic nanowires and nanotubes fabricated using porous templates. Ferromagnetic Ni and Fe nanowires with ...
