Abstract:
Water in the protein interior serves important structural and functional roles and is also increasingly recognized as a relevant factor in drug binding. The nonpolar cavity in the protein interleulcin-l beta has been reported to be filled by water on the basis of some experiments and simulations and to be empty on the basis of others. Here we study the thermodynamics of filling the central nonpolar cavity and the four polar cavities of interleukin-1 beta by molecular dynamics simulation. We use different water models (TIP3P and SPC/E) and protein force fields (amber94 and amber03) to calculate the semigrand partition functions term by term that quantify the hydration equilibria. We consistently find that water in the central nonpolar cavity is thermodynamically unstable, independent of force field and water model. The apparent reason is the relatively small size of the cavity, with a volume less than 80 similar to angstrom(3). Our results are consistent with the most recent X
-ray crystallographic and simulation studies but disagree with an earlier interpretation of nuclear magnetic resonance (NMR) experiments probing protein water interactions. We show that, at least semiquantitatively, the measured nuclear Overhauser effects indicating the proximity of water to the methyl groups lining the nonpolar cavity can, in all likelihood, be attributed to interactions with buried and surface water molecules near the cavity. The same methods applied to determine the occupancy of the polar cavities show that they are filled by the same number of water molecules observed in crystallography, thereby validating the theoretical and simulation methods used to study the water occupancy in the nonpolar protein cavity.

Title:
Molecular Dynamics Study of the Structures and Dynamics of the Iodine Molecules Confined in AlPO4-11 Crystals

Abstract:
Structural and dynamical properties of iodine molecules incorporated in one-dimensional elliptic channels of AlPO4-11 (AEL) crystals were studied by means of molecular dynamics (MD) simulations. It was found that the iodine molecules in the AEL channels are restricted in the (101) planes with only two favorite orientations: lying along the channels and standing along the major axes of the ellipses, which are well consistent with the experimental observations. In addition, the iodine structures are largely dependent on the loading level: with the increase of loading, the iodine specimens change their structures accordingly from isolated molecules as in the gas phase to single molecular chains and molecular ribbon sheets. The molecular ribbon sheets are composed of equally distributed and parallel molecules as in the iodine crystals. The simulation results show that the standing iodine molecules in the AEL channels are well restricted due to both the appropriate size of ellipse
s and their alternation throughout the channels. They can diffuse along the channels only after overcoming the rotational barriers to become lying molecules, which indicate that the iodine molecules in the ribbon sheets can keep the configurations without rotational and translational motion. The confined iodine molecules with such structures and properties may be used to improve the accuracy of the frequency standards.

Abstract:
Kinetic and thermodynamic properties of water encapsulation from organic solution by an open-cage [60]fullerene derivative have been investigated. 2D exchange NMR spectroscopy (EXSY) measurements were employed to determine the association and dissociation constants at 300 330 K (k(a) = 4.3 M-1 x s(-1) and k(d) = 0.42 s(-1) at 300 K) in 1,1,2,2-tetrachloroethane-d(2) as well as the activation energies (E-a,E-ass = 27 kJ mol(-1) E-a,E-diss 50 kJ mol(-1)). The equilibrium constants and thermodynamic parameters in various solvents (benzene-d(6), 1,2-dichlorobenzene-d(4), and dimethylsulfwdde-d(6)) were estimated using 1D-H-1 NMR spectroscopy. The parameters were dependent on the polarity of the solvent; Delta H depended linearly on the solvent polarity, becoming increasingly unfavorable as polarity increased. Mixtures of polar dimethylsulfoxide-do in less polar 1,1,2,2-tetrachloroethane-d(2) showed a similar trend.

Abstract:
Carbon nanotubes hold substantial and exciting promise as nanocontainers filled with fluid or nanopipes conveying fluid in their hollow cavity in nanotechnology. This paper studies the coupled vibration of embedded fluid-filled multiwalled carbon nanotubes (MWNTs) subject to axial load using the multiple-Euler beam model and considering the distinctive intertube deformation of carbon MWNTs. Through the numerical examples, the effective scope of the single-beam model is examined, and the effect of the internal fluid on the coupled vibration for various geometric dimensions, mass densities of the fluid, Winkler constants, axial loads, and mode numbers, is investigated. It is found that the influence of fluid coupling effect on the natural vibrating frequencies of fluid-filled MWNTs increases as the density of the fluid increases, or as the diameter of the innermost tube increases, or as the mode number studied decreases, and, the higher mode number n or density of the fluid rho
(f) is, the more intense the vibration of inner tubes are than that of outer tubes, and the more the vibration tends towards noncoaxial. (c) 2010 American Institute of Physics. [doi:10.1063/1.3480987]

Abstract:
The behavior of water, particularly the first water layer residing on solid surfaces with various unit cell sizes and charge defects, is studied by molecular dynamics simulations at room temperature. We found that both the unit cell size and presence of defects greatly affected the configurations of the first water layer, specifically the structure and stability of the two-dimensional hydrogen.-bond network within this layer. Consequently, the wetting behavior of water on the solid surface is significantly influenced. On certain wetted solid surfaces with water droplets distributed over the first water layer, the presence of defects at low ratios leads to partial disruption of the structure of the two-dimensional hydrogen-bond network within the first water layer and the existence of the irregular droplet profiles different from the conventional circular shapes. Due to the adsorption of the surface, the dwell time of the first water layer is extremely large and is about 1 ord
er of magnitude larger than the rest of the water layers.

Ferroelectric mobile water

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.

Abstract:
Amyloid-like fibrils from a number of small peptides that are unrelated by sequence adopt a cross-beta-spine in which the two sheets fully interdigitate to create a dry interface. Formation of such a dry interface is usually associated with self-assembly of extended hydrophobic surfaces. Here we investigate how a dry interface is created in the process of protofilament formation in vastly different sequences using two amyloidogenic peptides, one a polar sequence from the N terminus of the yeast prion Sup35 and the other a predominantly hydrophobic sequence from the C terminus of A beta-peptide. Using molecular dynamics simulations with three force fields we show that spontaneous formation of two ordered one-dimensional water wires in the pore between the two sheets of the Sup35 protofilaments results in long-lived structures, which are stabilized by a network of hydrogen bonds between the water molecules in the wires and the polar side chains in the beta-sheet. Upon decreasin
g the stability of the metastable structures, water molecules are expelled resulting in a helically twisted protofilament in which side chains from a pair of beta-strands in each sheet pack perfectly resulting in a dry interface. Although drying in hydrophobically dominated interfaces is abrupt, resembling a liquid to vapor transition, we find that discrete transitions between the liquid to one-dimensional ordered water in the nanopore enclosed by the two beta-sheets to dry interface formation characterizes protofilament assembly in the yeast prions. Indeed, as the two sheets of the hydrophobic A beta-sequence approach each other, fibril formation and expulsion of water molecules occur rapidly and nearly simultaneously.

Abstract:
Coaxial carbon nanotube/boron nitride nanotube (CNT/BNNT) multi-walled structures are ideal components in nanoelectronic systems. Our molecular dynamics simulations show that separate CNTs and BNNTs can self-assemble into stable coaxial structures in water under appropriate conditions. In case study three types of representative coaxial structures: (5, 5) CNT/(10, 10) BNNT, (5,5) BNNT/(10, 10) CNT and (5, 5) BNNT/(10, 10) BNNT are obtained. Simulation results also reveal that the self-assembly time between two separate BNNTs is increased remarkably due to the polarization of BNNTs in water. The mechanism of self-assembly among these tubes is demonstrated in detail. Further, coaxial (10, 10) BNNT/(10, 10) CNT/(15, 15) BNNT nanoheterojunctions are achieved for potential application in nanoelectronic systems. The present work shows the feasibility to fabricate the coaxial nanodevices such as insulating high-strength cables, high frequency oscillators and nanojunctions using self
-assembly approach. (C) 2010 Elsevier B.V. All rights reserved.

Abstract:
The current work suggests mathematical models for the vibration of double-walled carbon nanotubes (DWCNTs) subjected to a moving nanoparticle by using nonlocal classical and shear deformable beam theories. The van der Waals interaction forces between atoms of the innermost and outermost tubes are modeled by an elastic layer. The equations of motion are derived for the nonlocal double body Euler-Bernoulli, Timoshenko and higher-order beams connected by a flexible layer under excitation of a moving nanoparticle. Analytical solutions of the problem are provided for the aforementioned nonlocal beam models with simply supported boundary conditions. The dynamical deflections and nonlocal bending moments of the innermost and outermost tubes are then obtained during the courses of excitation and free vibration. Finally, the critical velocities of the moving nanoparticle associated with the nonlocal beam theories are expressed in terms of small-scale effect parameter, geometry, and ma
terial properties of DWCNTs.

Abstract:
A biomimetic nanochannel coated with a self-assembled monolayer (SAM) can be used for sensing and analyzing biomolecules. The interaction between a transported biomolecule and a SAM governs the mechanically or electrically driven motion of the molecule. To investigate the translocation dynamics of a biomolecule, we performed all-atom molecular dynamics simulations on a single-stranded DNA in a solid-state nanochannel coated with a SAM that consists of octane or octanol polymers. Simulation results demonstrate that the interaction between DNA and a hydrophobic or a hydrophilic SAM is effectively repulsive or adhesive, respectively, resulting in different translocation dynamics of DNA. Therefore, with proper designs of SAMs coated on a channel surface, it is possible to control the translocation dynamics of a biomolecule. This work also demonstrates that traditional tribology methods can be deployed to study a biological, or biomimetic transport process.

Abstract:
Grand canonical Monte Carlo simulations are used to examine the adsorption and structure of water in the interior of cylindrical nanopores in which the axial symmetry is broken either by varying the radius as a function of position along the pore axis or by introducing regions where the characteristic strength of the water-nanopore interaction is reduced. Using the extended simple point charge (SPC/E) model for water, nanopores with a uniform radius of 6.0 angstrom are found to fill with water at chemical potentials approximately 0.5 kJ/mol higher than the chemical potential of the saturated vapor. The water in these filled pores exists in either a weakly structured fluidlike state or a highly structured uniformly polarized state composed of a series of stacked water clusters with pentagonal cross sections. This highly structured state can be disrupted by creating hydrophobic regions on the surface of the nanopore, and the degree of disruption can be systematically controlled
by adjusting the size of the hydrophobic regions. In particular, hydrophobic banded regions with lengths larger than 9.2 angstrom result in a complete loss of structure and the formation of a liquid-vapor coexistence in the tube interior. Similarly, the introduction of spatial variation in the nanopore radius can produce two condensation transitions at distinct points along the filling isotherm. (C) 2010 American Institute of Physics.

Abstract:
Nanoscale particles have become promising materials In many fields, such as cancer therapeutics, diagnosis, Imaging, drug delivery, catalysis, as well as biosensors. In order to stimulate and facilitate these applications, there is an urgent need for the understanding of the nanoparticle toxicity and other risks involved with these nanoparticles to human health. In this study, we use large-scale molecular dynamics simulations to study the interaction between several proteins (WW domains) and carbon nanotubes (one form of hydrophobic nanopartides). We have found that the carbon nanotube can plug into the hydrophobic core of proteins to form stable complexes. This plugging of nanotubes disrupts and blocks the active sites of WW domains from binding to the corresponding ligands, thus leading to the loss of the original function of the proteins. The key to this observation is the hydrophobic Interaction between the nanoparticle and the hydrophobic residues, particularly tryptopha
ns, in the core of the domain. We believe that these findings might provide a novel route to the nanopartide toxicity on the molecular level for the hydrophobic nanopartides.

Abstract:
The kinetics of water filling narrow single-walled carbon nanotubes was studied using molecular dynamics simulations. The time required to fully fill a nanotube was linear with respect to the tube length. We observed that water molecules could enter into nanotubes of different lengths, either from one end or from both ends. The probability of having a nanotube filled completely from both ends increased exponentially with the tube length. For short tubes, filling usually proceeded from only one end. For long tubes, filling generally proceeded from both tube ends over three stages, i.e., filling from one end, filling from both ends, and filling from both ends with the dipole reorientation of water molecules to give a concerted ordering within the fully filled tube. The water molecules in the partially filled nanotube were hydrogen bonded similarly to those in the fully filled nanotube. Simulations for the reference Lennard-Jones fluid without hydrogen bonds were also performed
and showed that the filling behavior of water molecules can be attributed to strong intermolecular hydrogen bonding. (C) 2010 American Institute of Physics. [doi:10.1063/1.3509396]
