2. Laboratory Safety
Safety is an integral part of all
materials science laboratory courses. At the beginning of the quarter
the students are given a tour of the laboratories and shown the potential
hazards, safety features and resources in the laboratories, and a review the
emergency and evacuation procedures. Please visit the
laboratory safety page of this web site for additional information on this important
subject and to view documents that cover specific safety policies and procedures.

3. Laboratory Reports
Like all of the materials science laboratory
courses at U. C. Davis writing a report after concluding each experiment is
a big part of the course. In this course, where the experiments
deal with fairly complex subjects, students have tendency to write long,
detailed reports that review the principles and techniques employed as well
as the experiment. We'll focus our energies on writing about only the
immediate question that we want to answer using the results from this
experiment.
To help with this we have written a number of documents offering
guidelines, checklists, and suggestions that will help you write your
reports. Please visit the
laboratory reports page to see these documents.

4. Practical Devices
Demonstrations of Hall effect devices, reed relays (magnetostriction),
thermoelectric devices, piezoelectric devices, superconductivity, and devices based on other
magneto-electro-optical materials.Top |

5. Electrical Resistivity as a Function of Temperature
This experiment involves recording the change in resistance of 2-meter coils
of wire placed in a pre-heated tube furnace. Several materials are
tested, including steel, copper, brass, nichrome, and aluminum.

6. Fourier Transform Infrared Spectroscopy
This experiment covers the principles of FTIR and one of its many
applications, identifying unknown organic and polymeric materials.
| Procedure - Notes and the complete procedure for this experiment. |

8. Field Trip/Plant Tour
Field trips typically take the students to companies such as OCLI (JDS
Uniphase) in Santa Rosa to see how optical coatings are designed,
manufacturer and tested, or at Intel in Folsom where integrated circuits are
manufactured, all in an industrial environment where the students
have an opportunity to meet with practicing engineers and technicians and to
simply get a better idea of what it will be like to work as an engineer.Top |

9. Appendices
The appendices
page on this web site offers a number of documents that you will find useful during and after the laboratory
session. These include operating
procedures for the equipment, tips and trick for digital imaging, and documents that will help you get the
most out out your spreadsheet-based assignments and writing the laboratory
reports. The documents you should look are:
