Cylindrical inclusions in a copolymer membrane

Article Abstract:

The self-consistent field theory (SCFT) study is done to determine the membrane-mediated interaction between the two, parallel, cylindrical inclusions with regards to three energy components, the interfacial energy, entropy energy and the chemical potential energy. The observations indicate that the conformational entropy of the polymer chains is a direct contribution to the repulsive barrier and the weak attraction, and the chemical potential energy dominates the qualitative trend of the interaction energy.

Experimental phase diagram of symmetric binary colloidal mixtures with opposite charges

Article Abstract:

The phase behavior of equimolar mixtures of oppositely charged colloidal systems with similar absolute charges is studied experimentally by using the salt concentration and colloid density as control parameters. The simulations have predicted a reentrant liquid at low salt concentrations and as the gel transition is caused by a nonergocity transition, it is speculated that the fluid of clusters is the result of this nonergodicity transition in the fluid phase.

Symmetric double proton tunneling in formic acid dimer: adiabatic basis approach

Article Abstract:

A model of double proton tunneling in formic acid dimer is developed by using a reaction surface Hamiltonian, which has included the symmetric OH stretch plus the in-depth stretch and bend interdimer vibrations. The results are described within the framework of a diabatic representation of reaction surface modes.
