Comparison of carbon nanotube forest growth using AlSi, TiSiN, and TiN as conductive catalyst supports
(2014)We evaluate carbon nanotube growth by employing AlSi, TiSiN and TiN as conductive catalyst supports. Using a wide range of chemical vapour deposition conditions, we find that only AlSi and TiSiN yield homogeneously-sized ... -
Compositional and Structural Characterisation of Polymer Photovoltaic Devices
Organic materials have enormous relevance in material science and have many advantages over materials such as metals, ceramics and glass due to their physical and mechanical properties. They offer a viable alternative to ... -
The Effect of Network Formation on the Mechanical Properties of 1D:2D Nano:Nano Composites
(2018)Mixtures of 1D carbon nanotubes and 2D nanosheets are important in electrochemical applications where the nanosheets are the active material, while the nanotubes provide electrical conductivity and mechanical reinforcement. ... -
Liquid Processing of Interfacially Grown Iron-Oxide Flowers into 2D-Platelets Yields Lithium-Ion Battery Anodes with Capacities of Twice the Theoretical Value
(2022)Iron oxide (Fe2O3) is an abundant and potentially low-cost material for fabricating lithium-ion battery anodes. Here, the growth of α-Fe2O3 nano-flowers at an electrified liquid–liquid interface is demonstrated. Sonication ... -
Spin filter effect of manganese phthalocyanine contacted with single-walled carbon nanotube electrodes.
(2010)We present a theoretical study of the spin transport through a manganese phthalocyanine (MnPc) molecule sandwiched between two semi-infinite armchair single-walled carbon nanotube (SWCNT) electrodes. Ab initio modeling is ... -
Structural Modifications of Ionic Liquid Surfactants for improving the Capability to Disperse Single-Walled Carbon Nanotubes in Water: an Experimental and Theoretical Study
(2011)The 1-hexadecyl-3-vinylimidazolium bromide (hvimBr), a water-soluble long-chain imidazolium ionic liquid (IL) with surfactant properties, showed the ability to produce stable homogeneous aqueous dispersions of pristine ... -
Sudden decay of indirect exchange coupling between magnetic atoms on carbon nanotubes
(2008)Indirect exchange coupling plays a central role in determining the magnetic order in systems composed of adsorbed magnetic moments on a metallic host. For low-dimensional metallic structures, such as nanotubes, this ... -
Surface-Enhanced Raman Scattering from small numbers of purified and oxidised single-walled carbon nanotubes
(2012)Temporal fluctuations of surface-enhanced Raman scattering spectra of purified and oxidised single walled carbon nanotubes have been observed. SERRS spectra were recorded that possessed fluctuating spectral profiles, these ...
