How does the size of a gold nanoparticle affect its stability and interaction with water molecules? Perform a molecular dynamics simulation using appropriate software to investigate the behavior of gold nanoparticles of varying sizes in water. Analyze your results to determine the correlation between nanoparticle size and stability, and provide an explanation for any observed trends.

Calculate the HOMO-LUMO gap of a conjugated polymer consisting of 50 monomers, assuming that the polymer is periodic in the z-direction, using a density functional theory (DFT) program of your choice. Also, determine the absorption spectrum of the polymer in the UV-vis region, and predict its color in solution.
