Micro-ice-lens formation in porous solid
Webice through restrictions in the pore space as the bulk melting temperature is approached. I focus on the case where the porous medium is partially ice saturated beneath the warm-est lens at temperature T l < f and position z l f so that a frozen fringe is formed. Of prime importance is the net effect of intermolecular interactions that separate the
