7) Cite the differences in thermo-mechanical behavior between crystalline and amorphous polymers, and cite differences in behavior and molecular structure for thermoplastic and thermosetting polymers. 8) Describe 4 possible electron band structures for solid materials, and describe electron excitation events that produce free electrons/holes in (a) metals, (b) intrinsic and extrinsic semiconductors, and (c) insulators.

Responsibility:

You will be responsible for all lecture, quiz, and laboratory materials, class participation, advance reading, homework assignments, and four exams including one final exam. Exams, homework, and laboratory reports are to be entirely your own work using only the resources specified. When in doubt, ask. Ethical behavior is fundamental in any professional discipline. Cheating or similar improper conduct in even the most minor way will result at minimum, in a failing grade for the course. Further sanctions are likely in severe cases. Room 1500 Engineering. Attendance is required and will be counted in the “Participation” grade.

Integrity:

Class Meetings: Class will meet from 10:40 to 12:00 on Mondays and Wednesdays in

Quiz:

Homework and exam problems will be discussed in the quiz session. Each quiz section will meet every week starting on September 8. Attendance of the quiz is required and will be counted in the “Participation” grade. You should attend the quiz section assigned by the Registrar. Attendance at other times for additional help is allowed. Section Numbers 001 002 003 004 005 006 007

Laboratory:

You should have registered for one laboratory section. The laboratory portion of the course will meet in Room 2011 Manufacturing Engineering for two hours every other week, as arranged in the quiz sessions. The laboratory will begin the week of September 8th (an A-type week). A total

of six experiments must be performed and a report for each must be written and submitted. The lab manual should be downloaded and printed (prior to the lab) from http://blackboard.wayne.edu/ (will be posted shortly). Lab reports must be typed. Lab reports will be written as a group project. Lab reports will be due one week after the experiment is performed, except for the Tensile Test experiment. This lab report will be counted double for grading and the report will not be due until your next lab meeting, two weeks later. Additional detail is provided in the lab manual. Penalties will be applied for late reports at a rate of 20% of the total score per week or fraction thereof. Failure to complete the laboratory work will result in failure in BE1301, no matter how good your exam performance in the lecture course (BE1300). Safety glasses must be worn in the laboratory at all times.

Exams:

All exams will be close book. Only non-erasable writing utensils such as pens are allowed. Do not use pencils on your exam papers. Some formula and other information sheets will be provided as specified by the instructor. Most questions on the exams will cover materials similar to homework and examples, but each exam will have at least one question that goes somewhat beyond the homework and examples. Make-up exams will be given only by prior arrangement at least 7 days before the exam, and only for valid reasons. College policy states that anyone giving or receiving information during an exam will be given an immediately failing grade for the course. The teaching assistants are instructed to photocopy selected exam papers before giving them back. If you request regrade, submit a written request within 7 days of receiving your graded exam, stating the problem(s) to be regraded and reason(s). When such a request is submitted, we may regrade the complete exam. The final exam is a comprehensive exam covering all the chapters. No extra credit projects will be allowed. course, and (2) the student can complete the required materials without retaking course or requiring faculty supervision.
