This paper studies the effects of temperature and aperture size on the nanojet ejection process by means of molecular dynamics simulation using the Lennard-Jones potential. According to the analysis, it can be seen that the spurting atoms from the nanojet aperture are more evenly distributed as the temperature is increased. However, as the temperature lowers, the atoms easily concentrate on the...

It is known, that the Leonard–Jones (L–J) potential describes the interaction of atoms of simple non-polar gases [1]. However, at large distances between atoms the interaction forces fall faster, than it is described by the L–J potential [1]. The corresponding corrections (including light atoms) are suggested in papers [2]–[6]. These authors had a suspicion, that, for light atoms, either L–J fo...

Based on a recently introduced metric for measuring distances between configurations, we introduce distance-energy (DE) plots to characterize the potential energy surface of clusters. Producing such plots is computationally feasible on the density functional level since it requires only a few hundred stable low energy configurations including the global minimum. By using standard criteria based...

Based on the variational and perturbation theories of liquid state, at equilibrium conditions, an approximation technique is introduced through which it has been made possible the derivation of analytic relations for the thermodynamic properties of simple liquids in which the intermolecular potential can be represented by the Lennard-Jones (m-n) potential function. By the application of the har...

We discuss the phenomenon of physical aging in a well studied atomic model liquid, a binary mixture of particles interacting with Lennard-Jones potentials. We put emphasis on the different dynamical behaviours of the model as well as on the relations between the experimental and numerical timescales. The physics of aging is discussed within a well characterized thermodynamic framework, based on...

The density profiles of liquid-gas interfaces of binary mixtures are determined by xray reflectivity measurements. The surface tension γ is calculated from the measured data in the framework of the capillary waves theory. It is demonstrated that gradient theory can be used to investigate the van der Waals interaction between the different constituents of the liquid. The determination of Lennard...

The light (L) polypeptide chains of the human T-globulins carry antigenic determinants designated as group 1 or 2 (1-3). Allotypic determinants designated InV have been found in association with the L chains of 3,,-globulin (4). Natural ly occurring human ant ibody directed toward L chain determinants has been described in detail only for the InV antigens (5). The present studies utilize human ...

We reanalyse the cell theory of Lennard-Jones and Devonshire and find that in addition to the critical point originally reported for the 12−6 potential (and widely quoted in standard textbooks), the model exhibits a further critical point. We show that the latter is actually a more appropriate candidate for liquid-gas criticality than the original critical point. Typeset using REVTEX

in this paper, a new model based on kinetic theory of gases and longitude oscillations of metallic nanocluster on single carbon nanotube (cnt) in addition to phononvibrations of cnt on substrate is presented to describe the growth mechanism of ultra-long cnt in chemical vapor deposition (cvd).interaction between cnt and catalyst is investigated by lennard-jones potential. simulations demonstrat...
