Temperature dependence of Hamaker constants for fluorocarbons compounds

Article Abstract:

The variation of the surface tension with temperature is studied, introducing a temperature-dependent Hamaker constant and the concept of reversibility of the cohesive work. The observations revealed reasonable distances of closest approach between the slabs for all the cases, including dispersion contributions between the molecules of water as a special case.

Rate constants from uncorrelated single-molecule data

Article Abstract:

A method for estimating rate constants of a two-state Markov system from data obtained by a single-molecule (SM) type of experiment corrupted by white noise is described. The method is effective even when the characteristic (or resolution) time of the measurement is much longer than a characteristic time of the two-state system, and the data are uncorrelated.
