We report a simple chemical-route to BN multiwall nanotubes decorated with nanosheets. These nanostructures have been prepared on a large scale from a simple unique chemical process under an ammonia flow onto the surface of an alumina substrate, using carb ...
In this thesis, the electronic structures of low-dimensional carbon allotropes have been studied. In particular, the spatially-resolved photocurrent responses of devices comprising carbon nanostructures were investigated through scanning photocurrent micro ...
For many years, electron energy-loss (EEL) spectroscopy has been used to analyse the near-edge structure of the carbon ionization K-edge. Amorphous carbon has perhaps one of the most well known carbon ionization edges, with the spectrum featuring a large, ...
Supported metal catalysts are important from both an industrial and a scientific point of view. They are used, amongst others, in large-scale processes such as catalytic reforming, hydrotreating, polymerization reactions and hydrogenations. Often, these ca ...
Crystals with the scheelite structure have been grown by the Czochralski technique from a melt of composition (Na0.5La0.345Ce0.15Er0.005) MoO4 (NLM: Ce, Er) and have been characterized by scanning and transmission electron microscopy and x-ray microanalysi ...
The synthesis and characterization of a series of cobalt(III) complexes of the general type Co(N2O2)(L-2) are described. The N2O2 Schiff base ligands used are Me-salpn (H2Me-salpn = N,N'-bis(methylsalicylidene)-1,3-propylenediamine) (1-3) and Me-salbn ...
Using first-principles calculations, we model the chemical vapor deposition (CVD) growth of carbon nanotubes (CNT) on nanoparticles of late-transition (Ni, Pd, Pt) and coinage (Cu, Ag, Au) metals. The process is analyzed in terms of the binding of mono- an ...
This technical note describes the transfer of continuous, single-layer, pristine graphene to standard Quantifoil TEM grids. We compare the transmission properties of pristine graphene substrates to those of graphene oxide and thin amorphous carbon substrat ...
The local structure of TiBC and amorphous carbon (a-C) nanocomposite films (TiBC/a-C) was correlated with their optical and electrical properties. TiBC/a-C films with increasing C content were deposited by magnetron co-sputtering from TiC:TiB2 (60: 40) and ...
The anharmonic properties of low-dimensional carbon crystal lattices are reviewed. The energy and crystal momentum conservation rules in two- and one-dimensional crystals lead to a drastic reduction of the phase space available for anharmonic phonon decay. ...
