Hydrogenation of nanostructured carbon, synthesis of organic semiconductors and progress towards synthesis of fullerenes and nanoribbons from polyaromatic hydrocarbons
<p>The hydrogenation of carbon allotropes including fullerenes, nanotubes and graphene was investigated using polyamines as hydrogenation reagents. In each case, a rapid, scalable and reversible hydrogenation was observed. The mechanism of hydrogenation was explored using several different …

The Photosynthetic Action Spectra of the Phytoplankton and Their Role in Governing Spatial and Temporal Distribution: A Numerical Modeling Approach
… the relative size of diatom and dinoflagellate carbon synthesis along various marine light regime gradients. A radiative transfer model taking into account both Rayleigh and Mie atmospheric optical properties is employed to define the light regime incident on the sea surface. The hydrospheric …

Ultrasound Mediated Synthesis of Catalytic and Polymeric Materials
Polymer to diamond-like carbon. Synthesis of a carbon-based network polymer with an sp3 hybridized backbone which upon pyrolysis should yield a diamond-like carbon film. The rational design of an appropriate organic monomer and its polymerization to a network polymer whose weakest bond is between …

Enzymology and Physiology of a New Type of Phosphoenolpyruvate Carboxylase and the Development of a Pyruvate Carboxylase Expression System
… the cell. OAA production is critical for cell carbon synthesis in the methanogenic archaea. Therefore OAA-generating enzymes are essential for the survival of methanogens. In part of this study we investigated archaeal-type phosphoenolpyruvate carboxylase (PpcA), a new type of …

The formation of carbon nanofibers and thin films from the catalytic decomposition of ethylene by palladium
… catalyst toward the deposition of solid carbon from ethylene in two distinct forms: nanofibers and thin films. Four forms of palladium were tested: sputtered film, foil, sub-micron powder, and nanopowder. The deposition of carbon can be achieved by a very simple method. In this method …
