Wiring-up hydrogenase with single-walled carbon nanotubes.
Many envision a future where hydrogen is the centerpiece of a sustainable, carbon-free energy supply. For example, the energy in sunlight may be stored by splitting water into H2 and O2 using inorganic semiconductors and photoelectrochemical approaches or with artificial photosynthetic systems that seek to mimic the light absorption, energy transfer, electron transfer, and redox catalysis that ...
متن کاملWiring Neurons with Carbon Nanotubes
Carbon nanotubes (CNTs) are emerging as nanomaterials with a wide range of biomedical applications, including their potential use for neuroprosthesis (Bekyarova et al., 2005). Thus, an understanding of how CNTs interact with cellular components of the brain is important for engineering of CNT-based devices. The conductive properties and nanoscale features of CNTs make them better suited as an i...
متن کاملElectrodeposition and characterisation of polypyrroles containing sulfonated carbon nanotubes.
Using facile diazonium chemistry, sulfonate groups have been covalently attached to single wall carbon nanotubes. The resulting sulfonated tubes form a stable aqueous dispersion in the presence of pyrrole monomer. Subsequent electropolymerisation results in a conductive, electroactive polypyrrole doped with sulfonated tubes being formed at unusually low potentials. The potential of this materia...
متن کاملNarrow Carbon Nanotubes: Metals or Semiconductors?
We report local density functional results that show that narrow nanotubes with optimized diameters between about 0.34 and 0.5 nm can be either semiconducting or metallic, but with electron structures near the Fermi level that often cannot be understood starting from the graphene sheet model, successful in the study of larger diameter tubes. Our total energy calculations indicate that narrow na...
متن کاملCharacterization of single-walled carbon nanotubes catalytically synthesized from alcohol
High purity single-walled carbon nanotubes (SWNTs) were synthesized from ethanol by catalytic CVD method. The yield of SWNTs was determined based on TGA complemented by Raman and TEM analyses. The effects of CVD reaction time and pre-reduction of catalytic metal on the yield and quality of synthesized SWNTs were investigated. The SWNT yield of more than 40% was achieved over the weight of zeoli...
