Goals

To provide a basic understanding of the structure and processing of
powder, glass, semiconductor, optical, and composite ceramic materials.
T
o relate mechanical, electronic, optical, magnetic, and thermal properties
of these materials to defects, dopants, microstructure, and monetary and
environmental cost
-
benefit analyses.

Homeworks



There will be a total of 6
-
8 homework assignments; each set

will contain 3
-
4 problems. The HW
assignments

will
be posted on the
class web site

and the solutions will be made available at the
same site
only after all the HWs are received
.


All
HWs

are due by the star
t of class on the stated deadline. If you submit the
HW

no more than
24 hours late you will lose only 10%; if you submit the
HW

within 48 hours of the deadline you
will lose 25%; if you are 2
-
7 days late you will lose 50%, and beyond that you will earn no
credit
(
al
though I will correct them if you require feedback).



If you use material from sources beyond the text or class notes for
HW
s, you
must

reference
them appropriately (e
.
g.
,

other
texts, journals, web sites).


Remember that the
tests

draw heavily
from
HW
s

and class room discussions
. Solutions of the
HW
s will be posted on the course web site.


Partial credit for individual questions
will not

be given on
HW

assignments.




Tests


All
tests

will be closed book and notes.
Bring a calculator and a rule
r to all exams.

Pertinent
data, tables, and values for physical constants will be provided. All
tests

will be held during the
class and will last 75 minutes. Study guides will be provided before
the tests
.



You may bring a Letter sized paper of notes wit
h essentially
anything you want to write on
it written or sketched
in your own hand

writing
.



A make
-
up test towards the end of the semester will be provided to students who
miss
ed

a
test or
the final only
for verifiable emergencies. If this occurs, conta
ct me by phone and your academic
advisor as soon as possible.



Partial credit
for individual questions
will be

given on
tests
.

Term Project


The term project wil
l consist of a
contemporary

topic that teams may choose from a list
provided by the instructor

(see next page)
.
Teams may suggest other topics related to the
course material.



The goal of this project is to discuss
scientific, technological, social, and e
nvironmental

issues
related to this course.


Teams will consist of 4
-
5 students. I will assign teams based on your input regarding preferred
teammates
. I expect that the teams meet regularly (once a week) to discuss the term project once
the
teams have be
en set.
The term project will be due on the last day of
the

course
.


Only one report per topic

will be allowed from the class, so register early
after the teams have
formed
if certain topics are especially interesting. Also, please cancel them if you chan
ge your
mind.



For your term project:




Identify the scientific reason behind the issue.



Explain some technologically feasible solutions.



Discuss whether you think these solutions will make a difference to consumers. What
about manufacturers? Focus on que
stions of safety, cost, capability, reliability, the
environment, etc.
.



Discuss the social implications (if applicable)
.



Analyz
e environmental effects (if applicable)
.



Include references.


The report should be
5 pages or less

(
typed,
single spaced, 1” mar
gins), plus figures,
equations,
tables, and references.

Points will be given for quality, not quantity.


The goal is to think critically about materials science in the world around you by
identifying and understanding modern technological challenges, and t
o be able to
reasonably assess solutions that you find or imagine. Apply concepts you have learned in
class.

Topics




Mercury is hazardous, but is

also an important part of standard dental fillings.



As nanotechnology becomes more prevalent, researchers, manufacturers, and even
consumers may be exposed to nanoparticles.



Building materials still contain asbestos.



Paint and many other products

still co
ntain lead.



Semiconductor devices are frequently packaged using lead based solder.



Semiconductor facilities generate tremendous liquid and gaseous waste.



Parts of some semiconductor components can be recycled.



Transistors are hailed as the revolutionary in
vention of the 20
th

century.



Cell phone batteries occasionally catch fire or explode.



Cell phone size is still a bit large for futuristic applications (e.g. phone watch).



Space shuttle tiles fail.



Can magnetic hard drives get any smaller than they are now

(size/capacity)?



What is the difference in data storage in an iPod and iPod Nano?



What are applications of superconductors in real life? Are these materials just novelties?



How did MRI change our life?



Standard, incandescent light bulbs are not efficient
.



Ceramic bone implants tend to fail after 10
-
15 years.



Ceramic knives and hammers can be bought, but are essentially novelties.



Expensive sports equipment is available with piezoelectric sensors and actuators.



How would a commercially available night visi
on device change our life?



Laptop computers can get extremely hot.



Plasma television sets are extraordinarily expensive.



Self dimming mirrors and glass could be very useful but are still novelty items.



Carbon nanotubes hold tremendous potential for mechan
ical, thermal, and electronic
applications, but there are many types that are difficult to distinguish.



Scientists want to send experiments to other planets like Mars.

What would be the
materials requirements?



What are metamaterials? Are there any practica
l consumer applications?
