Welcome to the Materials Analysis and Research

November 1, 2011
MARL has instituted a new
sample submission form effective today. Users dropping off samples for
analysis will need to complete a form with each set of samples. Users doing work
on their own will also need to submit one form with each session.
Users are encouraged to save the form on
their own computer so they can fill out and save the basic information. They can
update the other information as it changes.
July 1, 2010:
MARL has joined the Office of Biotechnology as one of its core instrumentation
facilities. The lab will retain its location, staff, and policies and
procedures. The realignment will more clearly reflect MARL's role as a
campus-wide resource.
June 2010:
MARL has commissioned an FEI Quanta-250 field-emission with high
vacuum, variable pressure, and extended vacuum (i.e., environmental) modes of
operation. The FEI's stated resolution is just over 1 nm which is a three-fold
improvement over MARL's previous JEOL and Hitachi SEMs.
The Materials Analysis and Research Laboratory (MARL) is one of the core
instrumentation facilities administered by Iowa State University's Office of
Biotechnology. That office is part of the Office of the Vice President for
Research and Economic Development.
We are located in rooms 23
through 68 in the basement level of Town Engineering Building at the northwest corner of
the Iowa State University campus in Ames, Iowa (campus
map).
The laboratory includes equipment for:
- Scanning Electron Microscopy (SEM)
- Energy-dispersive x-ray spectroscopy (EDS)
- X-ray Diffraction (XRD)
- X-ray Fluorescence (XRF)
- Thermal Analysis (DTA, TGA, DSC)
Here are some links to the rest of the site:
- MARL WWW site (the detailed lab web pages)
- MARL ftp site (a repository of user files for
downloading. Sensitive files are stored in a password-protected area.)
Note: some browsers and sites may have problems, on their end, that prevent accessing
these files. First, try refreshing the page. Click here

- Thermal Analysis results
(TGA and DSC results ready as the runs are in progress)
- Interesting files
(this subdirectory has a number of interesting pictures)
- Utilities (this
directory includes several utilities including the PCI Viewer for images.)
- Pixera example files
(a collection of images taken with our Pixera CCD camera. The x-resolution makes up the
last part of the file name.)
