  • Carbon Nanomaterials: Building Blocks in Energy Conversion Devices
    Mimicking Photosynthesis Carbon nanostructure-based donor- acceptor molecular assemblies can be engineered to mimic natural photo- synthesis. Fullerene C60 is an excellent electron acceptor for the design of donor-bridge-acceptor molecular systems. Photoinduced charge transfer processes in fullerene-based dyads and triads have been extensively investigated by several research groups during the last decade. In these cases the excited C60 accepts an electron from the linked donor group Carbon Nanomaterials: to give the charge-separated state under visible light excitation.

  • The Raman Spectrum of Amorphous Diamond
    " r / J 1 U/Y/ — f> _ - ^ /lj / AU9715866 THE RAMAN SPECTRUM OF AMORPHOUS DIAMOND S.Prawer, K.W. Nugent, D.N. Jamieson School of Physics and Microanalytical Research Centre University of Melbourne, Parkville, Victoria, Australia, 3052. ABSTRACT: We present the Raman spectrum of an amorphous, fully sp^-bonded carbon network. The reduced Raman spectrum agrees closely with the calculated density of states of diamond. The results have been obtained from nanoclusters produced deep inside a single crystal diamond irradiated with MeV He ions. The deep implantation creates amorphous sp3 bonded C clusters along the ion tracks, within a largely intact diamond matrix. The matrix maintains the clusters under high pressure, preventing the relaxation to sp% bonded structures. Sharp peaks associated with defect structures unique to MeV ion implantation are observed at 1422, 1447, 1467, 1496, 1540, 1563, 1631, 1649, 1683 and 1726 cm'1. We also observe a shoulder in the reduced Raman spectrum at about 1120 cm'1 which we tentatively attribute to quantum confinement effects in the carbon nanoclusters. The results provide the Raman signature that might be expected from tetrahedrally bonded amorphous carbon films with no graphite-like amorphous components. 2 Tetrahedrally bonded amorphous (‘diamond-like ’) carbon has attracted a great deal of both experimental and theoretical interest of the past few years [1]. There have been numerous efforts to model the vibrational spectrum of sp3 bonded amorphous carbon networks, but until now there has been no experimental confirmation, in the form of a Raman spectrum, to test the accuracy of these model calculations. This is primarily because most sp3 rich amorphous carbon films contain a minimum of 5-15% of sp2 bonded carbon.

  • Closed Network Growth of Fullerenes
    ARTICLE Received 9 Jan 2012 | Accepted 18 Apr 2012 | Published 22 May 2012 DOI: 10.1038/ncomms1853 Closed network growth of fullerenes Paul W. Dunk1, Nathan K. Kaiser2, Christopher L. Hendrickson1,2, John P. Quinn2, Christopher P. Ewels3, Yusuke Nakanishi4, Yuki Sasaki4, Hisanori Shinohara4, Alan G. Marshall1,2 & Harold W. Kroto1 Tremendous advances in nanoscience have been made since the discovery of the fullerenes; however, the formation of these carbon-caged nanomaterials still remains a mystery. Here we reveal that fullerenes self-assemble through a closed network growth mechanism by incorporation of atomic carbon and C2. The growth processes have been elucidated through experiments that probe direct growth of fullerenes upon exposure to carbon vapour, analysed by state-of-the-art Fourier transform ion cyclotron resonance mass spectrometry. Our results shed new light on the fundamental processes that govern self-assembly of carbon networks, and the processes that we reveal in this study of fullerene growth are likely be involved in the formation of other carbon nanostructures from carbon vapour, such as nanotubes and graphene. Further, the results should be of importance for illuminating astrophysical processes near carbon stars or supernovae that result in C60 formation throughout the Universe. 1 Department of Chemistry and Biochemistry, Florida State University, 95 Chieftan Way, Tallahassee, Florida 32306, USA. 2 Ion Cyclotron Resonance Program, National High Magnetic Field Laboratory, Florida State University, 1800 East Paul Dirac Drive, Tallahassee, Florida 32310, USA. 3 Institut des Matériaux Jean Rouxel, CNRS UMR 6502, Université de Nantes, BP32229 Nantes, France. 4 Department of Chemistry and Institute for Advanced Research, Nagoya University, Nagoya 464-8602, Japan.

Received: 15 July 2020; Accepted: 24 July 2020; Published: 30 July 2020 Abstract: Amorphous carbons are disordered carbons with densities of circa 1.9–3.1 g/cc and a mixture of sp2 and sp3 hybridization. Using molecular dynamics simulations, we simulate diffusion in amorphous carbons at different densities and temperatures to investigate the transition between amorphous carbon and the liquid state. Arrhenius plots of the self-diffusion coefficient clearly demonstrate that there is a glass transition rather than a melting point. We consider five common carbon potentials (Tersoff, REBO-II, AIREBO, ReaxFF and EDIP) and all exhibit a glass transition. Although the glass-transition temperature (Tg) is not significantly affected by density, the choice of potential can vary Tg by up to 40%. Our results suggest that amorphous carbon should be interpreted as a glass rather than a solid. Keywords: amorphous carbon; liquid carbon; glass-transition temperature; molecular dynamics 1. Introduction Amorphous carbons are often described as one of the allotropes of carbon, along with graphite, diamond and fullerenes.

The deformation of these ultra-thin membranes was measured by recording topography images at different normal loads using contact mode AFM. The obtained force-distance relationship at the center of membranes was analyzed to evaluate both the Young’s modulus and pre-stress by FEA. From these measurements, Young’s moduli of 178.9 ± 32.3, 193.4 ± 20.0, and 211.1 ± 44.9 GPa were obtained for 3.7 ± 0.08, 6.8 ± 0.12, and 10.4 ± 0.17 nm thick membranes, respectively. Raman spectroscopy, X-ray photoelectron spectroscopy, and transmission electron microscopy were used for characterizing the chemical and structural properties of the films, including the content of sp2 and sp3 hybrid- ized carbon atoms.
