Pressure-induced crystalline-to-noncrystalline transformations of barium fluorozirconates: A probe of the medium range order of noncrystalline solids
The reversible pressure-induced transformation of crystalline barium fluorozirconates to noncrystalline solids is reported. The transformation is observed by in situ high pressure Raman spectroscopy. ...

A simple analytical solution is obtained for the screened Coulombic force between neutral lipid bilayers separated by thin water film within a model formally analogous to the ``spherical model'' for Ising systems. This model accounts for constraints on the surface charge density fluctuations imposed by the structure of lipid bilayers. The force is attractive at low and repulsive at high temperatures. A relationship between the system parameters and the temperature of the transition from the repulsion to attraction is established. At room temperature predicted force can be repulsive as well as attractive depending on the system parameters and on the assumptions.

  24. At very large separations between the surfaces [L>>epsilonwLambda0/4pigamma, where Lambda0 is the root of Eq. (20)] the second order terms in the Green's functions (proportional to epsilond/epsilonw) become important and the influence of the constraint defined by Eq. (1) becomes negligible. (If the constraint may be neglected, leading terms in the Green's functions cancel each other in the final expression for the force. We return to this effect in the Discussion section). Then the force is attractive, dependent on epsilond and independent of the size density and specific structure of the surface charged groups. This part of the interaction is closely related to a zero-frequency van der Waals (VDW) interaction between the surfaces and must be studied within the theory of VDW forces (Ref. 20). In this paper we study non-VDW forces dependent on the density and distribution of the surface charged groups, which are more important at shorter distances, and we neglect all terms proportional to epsilond/epsilonw.
