Abstract:

The goal of this project was to gain a basic knowledge on ice adhesion. In the course of the research we have studied experimentally and theoretically two of three main physical mechanisms of ice adhesion electrostatic interactions and hydrogen bonding. The contribution of the last mechanism. van der Waals interaction, was determined as a difference between the total adhesion and the former two mechanisms. Two new physical phenomena were discovered the effect of DC potential on adhesion of ice to metals and effect of ice electrolysis on ice adhesion. One book Physics of Ice and 8 papers were published and one patent was issued on the results of the project. Three invited talks one in Japan and six conference presentation were given. The grant supported two graduate and two undergraduate students at Dartmouth College.
