Osmosis and intermolecular force

Journal of Theoretical Biology, 1984
A hypothesis concerning the molecular-dynamical basis of osmosis is presented. According to this hypothesis, osmosis results from the attractive force between solute and water molecules, and the exclusion of the solute from the water transport channels of the membrane. Based on this hypothesis, the osmotic process is predicted to involve a large number

Theory of Intermolecular Forces [PDF]

Physics Bulletin, 1970
H Margenau and N R Kestner New York: Pergamon 1969 pp 359 price £4 10s The rapid growth in the development of computers has made a tremendous impact on many branches of scientific research. A result of this is that in the theory of intermolecular forces there has been much detailed progress in the last decade in carrying out calculations based directly

Microassembly by intermolecular forces

Journal of Applied Crystallography, 1988
The value of neutron and X-ray small-angle scattering for studying self assembly of molecular-sized units into interesting chemical and electrical structures is illustrated with three different types of system. The amphiphilic nature of a polyacetylene-polyisoprene [(CH)xPI] AB block copolymer and some of the structure arising from this are seen in ...

A molecular dynamics study of 1,1-diamino-2,2-dinitroethylene (FOX-7) crystal using a symmetry adapted perturbation theory-based intermolecular force field.

Physical Chemistry, Chemical Physics - PCCP, 2011
A dimer potential energy function for 1,1-diamino-2,2-dinitroethylene (FOX-7) has been developed using symmetry adapted perturbation theory based on a Kohn-Sham density functional theory description of the monomers [SAPT(DFT)].

Concurrence of Intermolecular Forces in Monolayers [PDF]

Japanese Journal of Applied Physics, 2006
Here we describe a new instrument for surface stress measurements in monolayers of self-assembled films–thiol molecules on a cantilever surface. The device is constructed on the basis of an atomic force microscope. Our main interest was the relation between electrostatic forces and hydrogen bonds forces acting in the thiol monolayers. It was shown that

Intermolecular forces in simple systems

Chemical Physics, 1977
Abstract A new, semi-empirical, method for the prediction of intermolecular forces introduced recently [Chem. Phys. Letters 36 (1975) 451] is assessed in the light of recently published dispersion forces coefficients and high precision SCF HF calculations of the repulsive interaction, performed by us, on closed shell spherical systems.

A reactive potential for hydrocarbons with intermolecular interactions

, 2000
A potential function is presented that can be used to model both chemical reactions and intermolecular interactions in condensed-phase hydrocarbon systems such as liquids, graphite, and polymers.

Intermolecular Forces in Liquids

Physical Review, 1929
The volume energy of liquids, ${E}_{v}$, is formulated, as in the Born and Land\'e theory of the lattice energy of crystals, in terms of attractive and repulsive forces varying with inverse powers of the distance, or volume, giving ${E}_{v}=\frac{\ensuremath{-}a}{{V}^{m}}\left[1\ensuremath{-}\frac{n}{m}{\left(\frac{{V}_{0}}{V}\right)}^{{n}^{\ensuremath{

Calculation of Intermolecular Force Constants from Polarizabilities

, 1956
Two quantum mechanical approximation formulas due to Slater and Kirkwood are modified empirically such as to relate the empirical intermolecular force constants of a two‐parameter potential to the average polarizabilities and the number of valence ...
