· Why PinPoint? And how does it work?
An approximately one-hour lecture about Pinpoint will be given. The working principle and the operation models will be discussed (Hertz, JKR and DMT). Terms like Young modulus, adhesion force, Poisson ratio, etc, will be clarified. Questions are welcomed at any time during the lecture. Introductory PinPoint Video (10 min)
· Interactive Demo Session One:
Lecture topics will be reinforced through demonstration and practice of PinPoint nanomechanical imaging on a Park Systems NX series AFM. Emphasis will be put in the different Pinpoint parameters and its effect in the young modulus calculation. PS-LDPE (Polystyrene with Low-density polyethylene) film will be used as demo sample to calculate the Young modulus. Questions are welcomed at any time during the session.
