X-ray reflectivity study of self-assembled thin films of macrocycles and macromolecules
Article Abstract:
The growth of self-assembled thin film structures containing sequential depositions of oppositely charged macromolecules and macrocycles was investigated using X-ray reflectometry. Experimental results showed that the average electron density of the thin film measured after a sequential deposition of macromolecules followed by macrocycles remained the same regardless of the number of depositions. On the other hand, the average thicknesses of alternately deposited macromolecules and macrocycles deposited at the initial fabrication stage were larger than those deposited after many depositions.

Solvation free energy of biomacromolecules: parameters for a modified generalized born model consistent with the AMBER force field
Article Abstract:
A study was conducted to determine generalized Born model parameters used along with AMBER force field for determining solvation free energies. The model characterizes a molecule as a discrete set of overlapping charged spheres imbedded in a polarizable dielectric continuum. The difference between the total energy of the system was utilized to obtain the electrostatic contribution to the solvation free energy. Results indicated the feasibility of using GB parameters to determine solvate free energies.

Turbulence decay in stopped flow experiments by measurements of electric dichroism
Article Abstract:
It has been possible to demonstrate the existence of scaling rules for the dimensions and time constants of vortices in decaying turbulence under stopped flow conditions. The development of a stopped flow electric field jump instrument with a high time resolution and a high sensitivity gives a valuable tool for investigating macromolecular reactions.
