This page summarizes the structure and goals of the class labs, and presents the background notes for each experiment.

Lab Structure and Goals

The class of typically 50 students is divided into nine lab groups. During each lab week, 9 separate 4-hour experiments run simultaneously under three topical themes. Each lab group conducts 1 of the 3 experiments grouped under each theme. Hence, each lab group will perform 3 experiments per lab week, totaling to 12 experimental sessions of 4 hours each over the course of the semester.

Each lab experiment is designed to give students first-hand experience with the concepts developed in the lecture subject 3.012. In addition, students gain familiarity with common tools for materials characterization, including differential scanning calorimetry (DSC), x-ray diffraction (XRD), scanning probe microscopy (AFM/STM), scanning electron microscopy (SEM), UV/Vis, Raman and FTIR spectroscopy, x-ray photoelectron spectroscopy (XPS), vibrating sample magnetometry (VSM) and dynamic light scattering (DLS).

To prepare for specific labs, students are provided with background notes tailored to the experiment to be conducted. The notes, linked in the table below, provide background information and suggest supplementary readings, but do not generally detail the specific experiments to be conducted, or the procedures involved.

Students are responsible for recording procedure, data, data analysis in their laboratory notebooks, and build their formal laboratory reports based on these recordings.
