Recently I participated in the Robert Welch Foundation Conference on „Chemistry of Self-Organizing Hybrid Materials”, Houston, Oct.25- 26, 2004. Selected topics below:
Objects and processes listed above require, amongst others, the knowledge
of effective iteraction potentials – refer to the following port of my talk.
Microscopic generators of the potential energy function Conference on „Chemistry of Self-Organizing Hybrid Materials”, Houston, Oct.25- 26, 2004. Selected topics below:

AVB/GROMOS - (quantum-classical)
SCC-DFTB - (quantum)
SCC-DFTB/GROMOS - (quantum-classical)

SCC-DFTB Method Conference on „Chemistry of Self-Organizing Hybrid Materials”, Houston, Oct.25- 26, 2004. Selected topics below:
(Self Consistent Charge Density Functional Based Tight Binding Method,
SCC DFTB, Frauenheim et al. Phys Stat. Sol. 217, 41, 2000)
basic DFT concepts:
New generation of charges capable reproducing electrostatic properties, in particular molecular dipole moments.

There are non-solved problems energy(like hydrophobic potentials), but it looks likein the near future we will have a new generation of effective (mean-field, mesoscopic) molecular interaction potentials, which can be applied to structure prediction problems (regardless of the type of biopolymers !)or ligand – biomolecule interactions.
