here to see an examples
of the research work done by Dr. Charit's group.
Our laboratory (Advanced
Materials Laboratory or AML) is located in McClure 422 and has
a floor area spanning over 1200 square feet. The lab is equipped with
a simultaneous thermal analyzer
(with capabilities of performing differential scanning calorimetry, differential thermal analysis, and
thermogravimetric analysis), Lindberg high temperature furnaces,
High Temperature Vacuum Furnace (up to 2000 degree C), Buehler Isomet 1000 cutting machine, high energy ball milling equipment (SPEX Mill 8000M), SPEX-2380 bench press,
an inert atmosphere glove box, TEM sample preparation kit (Gatan
Disc Punch, Fischione Disc Grinder and Twin-Jet Polisher), and a
facility including an Allied HighTech TwinPrep Grinder/Polisher.
The AML is equipped with three
mechanical test instruments: A Lever Arm (20:1) ATS 2335 Creep Tester that can perform tensile creep testing up to 1000
degree C in air; A universal tester (Instron 5982) primarily for
performing room temperature and high temperature tensile tests
(funded by a NE-UP
Infrastructure Grant) at different temperatures and strain
rates; and a Vickers microhardness tester (LECO LM100).

The Department of Chemical and Materials Engineering houses a
fully equipped machine-shop at the Buchanan Engineering Laboratory (BEL)
The Center for Electron Microscopy and Microanalysis, a
University of Idaho facility, has a LEO Supra 35VP field-emission-gun scanning
electron microscope (FEG-SEM), one AMRAY 1830 SEM, a JEOL transmission electron
microscope (TEM) and a Siemens D5000 X-ray diffraction equipment
are located in the McClure Hall and easily accessible.
Dr. Charit's group also utilizes
the state-of-the-art analytical instruments available at the
Center for Advanced Energy Studies (CAES) at Idaho Falls. These
include a High Resolution TEM, SEMs with Focused Ion Beam (FIB)
and Electron Backscatter Diffraction (EBSD) capabilities and Local
Electrode Atom Probe (LEAP). These instruments can provide
valuable information on the intrinsic structure of materials at
a very fine level. These instruments are used either as part of the funded ATR-NSUF users
facility projects or at a charge. A PhD student (Somayeh) is
these instruments as part of her dissertation work. Furthermore,
she uses the spark plasma sintering machine present at the
Advanced Materials Lab at CAES (in collaboration with Prof.
Darryl Butt, Boise State University).

A pressure resistance welding (PRW)
machine was purchased from the Centerline Ltd. using an AFCI
grant in the past. Currently, the machine is located at the
Instrumentation Shop at the CAES, Idaho Falls. Dr. Charit's
group has been successful in joining a variety of high
temperature metallic materials using the PRW machine.
