Boron induced surface modification of transition metals
… is a thermo-chemical surface treatment of metals in which boron atoms diffuse into the metal substrate and form hard metallic borides. As a result of boronizing, several properties such as hardness, wear resistance, corrosion resistance, and high temperature oxidation resistance improve …

Correlated Hartree-Fock band structures for transition metals
… to the calculation of electronic properties of transition metal systems with good metallic behavior. Hartree-Fock energy band structures employing nonlocal exchange are reported for paramagnetic and ferromagnetic nickel, palladium, and palladium hydride, and an approximate correlation correction …

Cerebral Amyloid Angiopathy and Transition Metals in Alzheimer's Disease
Alterations in brain metals homeostasis and particularly brain iron overload have been postulated to play a role in Alzheimer's disease, contributing to oxidative stress and neuronal injury; however, the source of this iron is not clear and may be due to metabolic derangement(s), failed iron …

Synthesis and Characterization of Bis-Phosphine Complexes with Transition Metals
… processes, from the concentration of precious metals from ores to the separation of longlived nuclei from radioactive waste as well as the removal of heavy metals from soils and water for remediation. The vast majority of extractants rely on the use of nitrogen, oxygen, sulfur or selenium as …

Alkyl-heteroatom Bond Forming Reactions from the Late Transition Metals
… formation is a potential high value reaction in transition metal catalysis, however, only a handful of examples of this fundamental coupling reaction step have been reported. Presented in this thesis are new efforts to promote this challenging reaction. Group 9 and 10 metals bound by the pincer …

Fluorocarbene, Fluoroalkyl, and Fluoride Complexes of First-Row Transition Metals
Fluorinated organic compounds play important roles in our society, as these products range from life-saving pharmaceuticals and agrochemicals, to fluoropolymers with extremely high thermal and chemical stability. Although elemental fluorine (F2) is the most reactive element, some fluoro-organic …

Enhancement of Platinum Cathode Catalysis by Addition of Transition Metals
In addition to overcoming the slow kinetics of the ORR, another critical issue to low temperature fuel cells is the gradual loss of performance due to the degradation of the cathode catalyst under the harsh operating conditions in fuel cells. In the second part of my study, the performance, …

Fischer and N-heterocyclic carbene complexes of Group (VII) transition metals
… carbene (NHCs) complexes of the group VII transition metals were investigated. By using density function theory calculations, the structural and electronic parameters could be elucidated and the fundamental bonding interactions between the carbene ligands and transition metals defined. The …

Solvent extraction of first-row transition metals by thiosubstituted organophosphinic acids
… of the solvent extraction behavior of first-row transition-metal ions from manganese to zinc in acidic sulfate solution by these reagents is reported. Distribution coefficients shift to lower pH with increasing sulfur substitution of the extractant, the greatest effect being observed for soft …
