Isotopic effects of hydrogen adsorption in carbon nanotubes [PDF]
, 2001 We present diffusion Monte Carlo calculations of D$_2$ adsorbed inside a narrow carbon nanotube. The 1D D$_2$ equation of state is reported, and the one-dimensional character of the adsorbed D$_2$ is analyzed.

Bertrand versus Cournot with Convex Variable Costs [PDF]
, 2015 Within a simple model of homogeneous oligopoly, we show that the traditional ranking between Bertrand and Cournot equilibria may be reversed. For price setting entails a continuum of price equilibria under convex variable costs, departure from marginal ...

Neural Paraphrase Identification of Questions with Noisy Pretraining [PDF]
SWCN@EMNLP, 2017 We present a solution to the problem of paraphrase identification of questions. We focus on a recent dataset of question pairs annotated with binary paraphrase labels and show that a variant of the decomposable attention model (replacing the word ...

Materialwissenschaft und Werkstofftechnik, 2021 Functionalized single‐wall carbon nanotubes (f‐SWCN) are dispersed in chitosan films by self‐assembly of both components in aqueous media. This carbon form is a promising nanofiller to achieve nanocomposites with refined thermal, mechanical and surface ...

Aharonov-Bohm Oscillation and Chirality Effect in Optical Activity of Single Wall Carbon Nanotubes
, 2004 We study the Aharonov-Bohm effect in the optical phenomena of single wall carbon nanotubes (SWCN) and also their chirality dependence. Specially, we consider the natural optical activity as a proper observable and derive it's general expression based on ...

Formation of ice nanotube with hydrophobic guests inside carbon nanotube [PDF]
, 2005 A composite ice nanotube inside a carbon nanotube has been explored by molecular dynamics and grandcanonical Monte Carlo simulations. It is made from an octagonal ice nanotube whose hollow space contains hydrophobic guest molecules such as neon, argon ...

Raman frequency shift in oxygen functionalized carbon nanotubes
, 2007 In terms of lattice dynamics theory, we study the vibrational properties of the oxygen-functionalized single wall carbon nanotubes (O-SWCNs). Due to the C-O and O-O interactions, many degenerate phonon modes are split and even some new phonon modes are ...
