Facilities and Equipment

 

At the GREEN Center, we are committed to developing research infrastructure for the state of Arkansas. All equipment purchased with EPSCoR funds will be housed in user facilities and available for users in academia and industry. Our infrastructure is located in Fayetteville, Little Rock, and Fort Smith. All ASSET-affiliated infrastructure can be seen at the Arkansas Multi-User Instrument Database.

 Fayetteville

Most of the research that takes place at the University of Arkansas occurs in the Engineering Research Center (ENRC), on the campus of the Arkansas Research and Technology Park (ARTP). Dr. Fisher Yu, Dr. Hameed Naseem and Dr. Vijay Varadan all have laboratories in this building. All four of the professors belong to the Electrical Engineering department, while the graduate students work within the Electrical Engineering department as well as the Microelectronics-Photonics (MicroEP) program. The GREEN Center's largest aquisition was the JEOL JBX 5500F E-beam lithography system, one of only three of its kind in the United States, housed in the High Density Electronics Center (HiDEC). This is the only EBL facility located in the surrounding six EPSCoR state area (AL, KS, LA, MO, MS, OK).

 Little Rock

Our Little Rock facilities are located on the campus of the University of Arkansas, Little Rock (UALR). The researchers belong to both the department of Physics & Astronomy in the College of Science and Mathematics and the department of Systems Engineering in the Donaghey College of Engineering and Information Technology.

The Atomic layer deposition (ALD), located in Dr. Chen's laboratory
The X-ray photoemission spectrometer (XPS), located in Dr. Chen's laboratory
The Shimadzu DSC 60A Differential Scanning Calorimeter, located in Dr. Bhattacharyya's laboratory
The four-point resistivity measurement set-up with environmental chamber for heating and cooling, located in the Smart Materials & MEMS Laboratory, directed by Dr. Bhattacharyya. The set-up contains the following equipment:
1) Instron tensile testing machine model 1122
2) Instron environmental chamber model EC 23 A
3) Source meter: Keithley 2400
4) Nano Voltmeter: Keithley 2182
5) Four-point probe

 Fort Smith

Our facilities in Fort Smith are located on the campus of the University of Arkansas at Fort Smith in the Baldor Technology Center. Equipment includes MARCRAFT panels used to teach solar PV project classes that offer UAFS students a chance to become certified solar installers/technicians and energy auditors.
