First principles studies on band structures and density of states of graphite surface oxides
Graphite oxide constitutes carbon network with oxygen atoms both on hexagonal arrangement and the edge sites. Structural and electronic properties for graphite-oxygen complexes have been explored using first-principles total-energy calculations within the local density approximation (LDA). Band structures and density of states for the propose carbon 3D models are reported. A finite energy gap and...
متن کاملStudies on the preparation and rearrangement of certain steroid oxides.
By preparative methods developed by Chakravorty and Wallis (1) and improved by Hicks, Berg, and Wallis (2) and by Alther and Reichstein (3) the 3(a)-hydroxycholenic acids containing double bonds at the C&& and the C1l-Clz positions respectively are readily available. An attractive method, therefore, for introducing oxygen either as a ketone or as a secondary hydroxyl at the Cn position lies in ...

متن کاملSynthetic, spectroscopic, and structural studies on organoimido molybdenum, tungsten, and rhenium phthalocyanines.
Unprecedented imido phthalocyaninato complexes of pentavalent refractory metals [PcM(NR)Cl] (M = Mo, W, Re; R = tBu: 1, 3, 6, Mes: 2, 4, 7 or Ts: 5) have been synthesized by reductive cyclotetramerization of phthalonitrile in the presence of appropriate bis(imido) complexes of Mo, W and Re as templates. While d(1) Mo(V) and W(V) species 1-5 show distinctive EPR spectra corresponding to metal ce...
