Dr. Harald Reichert –
Ice in Confinement
|
 |
|
|
Ice is abundant on the earth's surface, in the planetary system
and in interstellar space. In our natural and technical
environment ice occurs in many different forms, from glaciers
and permafrost to atmospheric ice or ice films on airplane
wings or windows. Ice is of fundamental importance for many
processes and phenomena, from global change and biological
processes to safety issues. Upon melting all the properties of
ice are drastically changed. Therefore, the knowledge of the
stability range of ice and the various conditions for melting
of ice are of key importance to understand and control
ice-related phenomena and processes in nature and technology.
It turns out that the structure of the H2O molecule and of the
hydrogen-bonding network which stabilizes ice renders the
melting of ice a rather complex phenomenon full of
anomalies which by themselves have immediate consequences
for our biosphere. In this project we are dealing with
structural anomalies of ice interfaces during melting
and the possible impact onto environmental processes.
For this purpose we have developed new structural probes
based on high energy microbeams which allow to study
deeply buried interfaces with atomic resolution.
