The Shape of Bucky Onions
The morphology of Bucky onions is investigated by ab initio calculations using Yang’s new O(N) method. It is found that for large single shell fullerenes with Ih symmetry, the spherical morphology has the lower energy than that of polyhedrons. The formation energy per atom follows a simple scaling law. Including an estimate of inter-shell van de Waals interactions leads to the conclusion that s...
متن کاملSelf-organized scale-free networks.
Growth and preferential attachments have been coined as the two fundamental mechanisms responsible for the scale-free feature in complex networks, as characterized by an algebraic degree distribution. There are situations, particularly in biological networks, where growth is absent or not important, yet some of these networks still exhibit the scale-free feature with a small degree exponent. He...
متن کاملCarbon Nanotubes Filled with Ferromagnetic Materials
Carbon nanotubes (CNT) filled with ferromagnetic metals like iron, cobalt or nickel are new and very interesting nanostructured materials with a number of unique properties. In this paper we give an overview about different chemical vapor deposition (CVD) methods for their synthesis and discuss the influence of selected growth parameters. In addition we evaluate possible growth mechanisms invol...
متن کاملSize Effect on Failure of Pre-stretched Free-Standing Nanomembranes
Free-standing nanomembranes are two-dimensional materials with nanometer thickness but can have macroscopic lateral dimensions. We develop a fracture model to evaluate a pre-stretched free standing circular ultrathin nanomembrane and establish a relation between the energy release rate of a circumferential interface crack and the pre-strain in the membrane. Our results demonstrate that detachme...
متن کاملFree-Standing Self-Assemblies of Gallium Nitride Nanoparticles: A Review
Gallium nitride (GaN) is an III-V semiconductor with a direct band-gap of 3.4 eV. GaN has important potentials in white light-emitting diodes, blue lasers, and field effect transistors because of its super thermal stability and excellent optical properties, playing main roles in future lighting to reduce energy cost and sensors to resist radiations. GaN nanomaterials inherit bulk properties of ...
