Nanoscale friction of electrolyte molecules

Tuesday (18.06.2019)
12:30 - 12:45

Friction between solid surfaces is an important phenomenon in everyday life. A

large portion of the total energy production in industrialised countries is

lost through friction and wear. Friction is a very complex phenomenon with

dynamics happening on many length and time scales. At the most basic level,

however, is the dissipation at the nano-scale level. Many realistic surfaces

are covered in molecules, especially organic molecules and electrolytes in

solutions such as lubricants. I will discuss theoretical approaches based on

simple models for studying how adsorbed molecules affect the friction at the

nano scale and how they can be used to manipulate it.
