Equipment
The equipment listed below is owned and maintained by the Fakhraai Research Group, unless otherwise noted. Access to equipment in the Fakhraai Research Group requires pre-approval of Professor Fakhraai.
Woollam Ellipsometers:
The Fakhraai group has two Woollam M2000 spectroscopic ellipsometers with a spectral range of 400-1700nm. These ellipsometers are capable of measurements at variable angles, and one is equipped with an automatic scanning stage for large area scanning measurements. The group also has a Linkam ellipsometry stage that allows temperature and environmental control of the samples for thermal degradation and glass transition temperature measurements. Other capabilities include in-situ solvent vapor annealing, humidity control, and in-situ electrochemical measurements.

Q2000 Differential Scanning Microscope:
Fakhraai lab hosts and maintains a shared DSC instrument obtained through a University of Pennsylvania research fundation grant. This instrument is used to obtain the bulk Tg values of molecules.
UHV Chamber:
The group has a custom made ultra-high vacuum chamber with a base pressure of 3*10-8 torr. This instrument has been used to produce excptionally stable glasses of TPD, TNB and various molecules synthesized in Walsh lab..
Mini UVH Chamber:
This instrument has been used to produce exceptionally stable glasses of organic and inorganic materials.
Bruker AFM:
Bruker Dimension Icon AFM is a large sample AFM, going up to 90microns across in size. It can be modified to do contact, intermittent contact, and non-contact measurements. Our capability with this instrument ranges from electrochemical to annealing experiments.
Agilent AFM:
The group also owns an Agilent 5500 AFM with two closed loop scanners, one high resolution scanner and various environmental sample stages with temperature and liquid imaging capability. The scanners can be used separately either as a dedicated AFM-Raman system or a stand-alone AFM that is mounted on a vibration isolation table.

Olympus BX51 Microscope:
The upright microscope has polarization, dark and bright field and DIC imaging capabilities. Combined with a Linkam heating stage, studies of crystallization and morphology of various glassy samples are possible.
Wet Chemistry Lab:
The wet chemistry lab is equipped with a fume hood, spin coater, ovens, centrifuge and other necessary equipment.
Olympus IX81 TIRF Microscope:
The automatic inverted microscope has an integrated spectrometer and can be used in combination with the Agilent AFM for simultaneous AFM/TIRF imaging.
