Exercise 2.4 - Oscillating droplet tribometer

Optical Tweezers Measurements


tweezers_explanation
Content of the work 

In this experiment, we will investigate forces acting on a ferrofluid droplet that moves on a superhydrophobic surface utilizing a ferrofluid oscillator. We will carry out some experiments as explained in the attached files, and use matlab to analyze the data. Pre-reading materials are provided in the files. Please familiarize yourself with the materials.

Schedule

Reservations can be made via this link.

Location: Nanotalo, Puumiehenkuja 2 A, 02150 Espoo. Meet the assistant before the session in the lobby.


Report

The first version of the report must be returned to the exercise assistant electronically no later than three weeks after making the measurements. The writing time for the second revised version, in turn, is two weeks, calculated from the assistant's invitation to the feedback session.

The reports will be returned to the assistant by email.

Material and measurement

Read carefully the instructions, where more information on the experiment and report can be found. In addition, read the sections "Kurssin suorittaminen" and "Selkkariohjeita" in MyCourses.
