Molecular simulation of the carbon nanotube growth mode during catalytic synthesis
(AIP Publishing, 2008-06-01)
Catalyzed growth of carbon nanostructures occurs mainly through two modes, i.e., base growth when the metal nanoparticle remains at the bottom of the nanotube, or when it is lifted by the growing carbon nanostructure due ...
Optical Sectioning For Optical Scanning Holography Using Phase-Space Filtering with Wigner Distribution Functions
(Optical Society of America, 2008-10-01)
We propose a novel optical sectioning method for optical scanning holography, which is performed in phase space by using Wigner distribution functions together with the fractional Fourier transform. The principle of ...
Point vortex dynamics: A classical mathematics playground
(AIP Publishing, 2007-06-01)
The idealization of a two-dimensional, ideal flow as a collection of point vortices embedded in otherwise irrotational flow yields a surprisingly large number of mathematical insights and connects to a large number of areas ...
Molecular simulation study of structural and dynamic properties of mixed DPPC/DPPE bilayers
(CELL PRESS, 2006-06-01)
Molecular dynamics simulations have been used to study structural and dynamic properties of fully hydrated mixed 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) and 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine (DPPE) ...
A computational study of nucleosomal DNA flexibility
(CELL PRESS, 2006-12-01)
Molecular dynamics simulations of the nucleosome core particle and its isolated DNA free in solution are reported. The simulations are based on the implicit solvent methodology and provide insights into the nature of ...
The kinetics of analyte capture on nanoscale sensors
(CELL PRESS, 2006-03-01)
This article presents a number of kinetic analyses related to binding processes relevant to capture of target analyte species in nanoscale cantilever-type devices designed to detect small concentrations of biomolecules. ...
Diffraction theory of nanotwin superlattices with low symmetry phase: Application to rhombohedral nanotwins and monoclinic M-A and M-B phases
(American Physical Society, 2007-07-17)
The Brillouin zone-dependent conditions for coherent and adaptive diffractions are formulated. Adaptive diffraction phenomenon of nanotwins is analyzed. Extraordinary Bragg reflection peaks appear and adaptively shift along ...
The Effects of Text Drawing Styles, Background Textures, and Natural Lighting on Text Legibility in Outdoor Augmented Reality
(MIT Press, 2006-02-01)
A challenge in presenting augmenting information in outdoor augmented reality (AR) settings lies in the broad range of uncontrollable environmental conditions that may be present, specifically large-scale fluctuations in ...
Direct observation of the near-surface layer in Pb(Mg1/3Nb2/3)O-3 using neutron diffraction
(American Physical Society, 2004-11-19)
Spatially resolved neutron diffraction as a function of crystal depth in Pb(Mg1/3Nb2/3)O-3 reveals the presence of a distinct near-surface region where a strong distortion in the lattice exists. A dramatic change in both ...
High-performance photovoltaic behavior of oriented purple membrane polymer composite films
(CELL PRESS, 2003-04-01)
The photovoltaic behavior of films in which bacteriorhodopsin molecules are embedded in a polyvinyl alcohol matrix has been investigated by using both pulsed laser excitation and regular light illumination. Response times ...
