Extended Hansen method

With their method, Skapski et al. [ 1041 measured the surface stress of the ice-water interface to be 120 mN/m. This agrees with a more recent result of Hansen et al who report a value of I30 mN/m for the ice-water interface [ 105]. By using a combination of NMR and calorimetry to detect the melting, they extended the method to porous solids instead of a wedge. A surface stress around 120 mN/m is, however, surprisingly high. Earlier experimental and theoretical results were in the range of 10-35 mJ/m 1106. ... 

Here p,(r) is the local density distribution of HS component /. The weighting function takes the same mathematical expression as in Eq. (16) with the involved HS diameter being replaced by The extension to nonadditive HS mixture is a little bit tricky, and a few methods (Ayadim and Amokrane, 2010 Matthias, 2004, 2011) have been developed, and the accuracies of these extensions are rather striking. Recendy, the FMT has been extended to sticky HS fluids (Hansen-Goos and Wetdaufer, 2011) and to nonspherical hard-convex systems (Hansen-Goos and Mecke, 2009 Hendrik and Klaus, 2010). 

Nowadays, this view of electron density has been refined and extended by more sophisticated topological analysis. Modem methods are based on accurate experimental (or calculated) electron density distributions. Hansen and Coppens developed the finite multipole expansion (multipole model, MM) [40], which partitions...
