Abstract:
In molecular dynamics simulations single-domain ferroelectric water is produced under ordinary ambient conditions utilizing carbon nanotubes open to a water reservoir. This ferroelectric water diffuses while keeping its proton-ordered network intact. The mobile/immobile water transitions and the step-wise changes in net polarization of water are observed to occur spontaneously. The immobile water becomes mobile by transforming into the single-domain ferroelectric water. Our general notion of relating a more highly ordered structure with a lower temperature has so far restricted researchers' attention to very low temperatures when experimenting on proton-ordered phases of water. The present study improves our general understanding of water, considering that the term 'ferroelectric water' has so far practically stood for 'ferroelectric ice,' and that single-domain ferroelectric water has not been reported even for the ice nanotubes.

Abstract:
In this paper, the viscosity of water confined in single-walled carbon nanotubes (SWCNTs) with the diameter ranging from 8 to 54 is evaluated, which is crucial for the research on the nanoflow but difficult to be obtained. An "Eyring-MD" (molecular dynamics) method combining the Eyring theory of viscosity with the MD simulations is proposed to tackle the particular problems. For the critical energy which is a parameter in the "Eyring-MD" method, the numerical experiment is adopted to explore its dependence on the temperature and the potential energy. To demonstrate the feasibility of the proposed method, the viscosity of water at high pressure is computed and the results are in reasonable agreement with the experimental results. The computational results indicate that the viscosity of water inside SWCNTs increases nonlinearly with enlarging diameter of SWCNTs, which can reflect the size effect on the transports capability of the SWCNTs. The trend of the viscosity is well expl
ained by the variation of the hydrogen bond of the water inside SWCNTs. A fitting equation of the viscosity of the confined water is given, which should be significant for recognizing and studying the transport behavior of fluid through the nanochannels.

Abstract:
This paper is concerned with the free vibration of the fluid-filled multi-walled carbon nanotubes (MWCNTs) with simply supported ends. Based on Donnell's cylindrical shell model and potential flow theory, the effects of internal fluid and the different radii on the coupling vibration of the MWCNT-fluid system are discussed in detail. The results show that the fluid has only a little influence on the natural resonant frequency (frequency of the innermost tube) and the associated amplitude ratio in MWCNTs, while it plays a significant role in the intertube resonant frequency and the associated amplitude ratio. For the natural resonant frequency, the vibrational mode is almost coaxial, i.e., the MWCNTs vibrate like a single-layer shell, however, for the intertube resonant frequency, the system shows complex noncoaxial vibration, which plays a critical role in electronic and transport properties of carbon nanotubes (CNTs). Simultaneously, the effect of the innermost radius on the
frequencies of MWCNTs is also examined and the conclusions accord well with those of another paper.

Abstract:
We investigated the catalytic effect of CuO nanoparticles confined in carbon nanotubes using molecular dynamics simulations and density functional theory calculations. Ozone decomposition and hydroxyl radical generation were used as the probe reactions to investigate the catalytic behavior of catalyst. The effects of the confined environment of carbon nanotubes induced more reactants into the channel. Interface interactions between reactants and CuO nanoparticles in the channel and charge transfer accelerated the decomposition of ozone into oxygen molecule and atomic oxygen species. The atomic oxygen species then interacted to water molecule to generate hydroxyl radicals, which were truly identified by electron paramagnetic resonance (EPR) technique. (C) 2010 Elsevier B.V.

Abstract:
In this paper, the dynamic behavior of a fixed-fixed double-walled carbon nanotube (DWCNT) conveying fluid is studied based on Euler-Bernoulli beam theory. The viscosity of the fluid and the nonlocal effect are incorporated in the formulation, and the Galerkin discretization method is used to solve the coupled equations of motions. The critical flow velocity of the fluid is obtained. Numerical simulations show that the van der Waals (vdW) interactions and the internal moving fluid play significant roles in the natural frequencies and the instability of DWCNTs. Also, the influences of the viscosity, nonlocal effect, aspect ratio and the surrounding elastic medium on the dynamic behavior of the double-walled carbon nanotube is studied in detail. It is found that a higher viscous-fluid-conveying DWCNT embedded in a stiff matrix with a larger aspect ratio make the induced instability vibration occur until a higher flow velocity.
