Dear all,
Attached are the SEM images.

Dear all,
Some of you have e-mail accts that are over quota so
the message bounced back. I will upload the images onto the blog so
you can access them from there.
I made some corrections to the "intro to SEM" document, so you should
follow the questions on the latest version which is attached. Also,
I will attach on the blog what I think are the most representative images of what
you are trying to show in each step, rather than just sending you your
individual images from each group. For example, BSE_Al_03 shows the
carbon tape, epoxy and aluminum while using the backscatter detector.
When writing up your lab reports, use the same format you've been
using for the other lab reports. When writing the intro, you should go
in depth (in your own words) about the theory and what is happening
when an electron hits the sample. If it helps you can add schematics,
formulas, etc.
For the data analysis section, please do not blow up the images to
take up the whole page. You can easily fit several images together
onto one side of a sheet of paper, number them and in your discussion
(after the images) refer to those numbered images.
For your data analysis, you should be able to explain what each
image is showing. IOW, how the electrons are interacting with the
sample and how this gives us certain type of information. For example,
why does the BSE image looks different than secondary? What does going
to a lower kV do to the sample resulting in a different image than
higher kV. What are the trade-offs?
After your data analysis section answer the questions that are at
the end of your 'intro to SEM' document. Please number the answer
according to the number of the question. You do not have to re-type
the question. Then your conclusion comes after the questions.
The labs are due Wednesday 11/11 at noon in the folder in the 'nanomaterials group' mailbox in the MSE dept office.

Dear class,
Please print the "Intro to SEM" document for your lab. At the very least, read it so you know what to do. It outlines what you need to do in the lab this week.

Epon sample 2

Unknown metal. Ni? no... Fe???... nope! Hint: Comet!

Epon sample 1

Hi class,
attached you will find 3 measurement-files. Please analyze the Load-Displacement curves and discuss the following:
1.) Which materials did we test? Hint: One sample is Epon828, another sample is Epon828 with the addition of Nanodiamond. The third samples is a metal.
2.) What can you tell about their mechanical properties? How much plastic deformation and creep do we have?
Have fun!,

Dear all,
This is a nice website that might be helpful in understanding the Raman effect.

Dear all,
Attached is the raw data for the Raman lab. We gave them German names for the time being.
