Hi everyone, In this paper ( http://pubs.acs.org/doi/abs/10.1021/la962131c ), the authors calculate the surface energy of polymer and the contact angle of various liquids on these polymers using a so-called "liquid - polymer equilbrium contact dsitance". I'm wondering how to calculate such a...

Hi, Does anyone know where I can find the dielectric function of PTFE (Teflon) ? Thank's

Yes, i need it as a function of frequency

Hi, Does anyone have a dielectric function for ethanol or a paper where I can find it ? Thanks

Hi everyone, Decades ago, Derjaguin calculated formula which was able to predict the contact angle of a droplet on a solid substrate. The droplet and the solid substrate are separated by a thin liquid interlayer. This formula was cos(θ) = 1 + G(h0)/γ where θ is the contact angle of the droplet...
