Services and Policies:

The UAB Department of Chemistry Nanomaterials/Surface Characterization Facility is available to UAB researchers, government users, users from other universities, and industrial customers.  We provide nanomaterials/surface characterization services including consultation, data collection, and data processing.  Fees are charged on a per-sample basis (see fee schedule). Collaborations with university and industrial are encouraged. Users should e-mail to book their time.   


Spectroscopic ellipsometer

Woollam M2000-U (J. A. Woollam Co., Inc.) multi-angle spectroscopic ellipsometer (240-1000 nm spectral range) with a CompleteEASE analysis software is used for monitoring film thickness upon deposition and thickness changes upon changes in the environment. It is equipped with a 5 mL heated liquid cell. The cell allows the user to perform ellipsometric measurments on samples within a transparent liquid environment over the temperature range of room to 50C with 0.2C precision (the cells angle of incidence is 750. The cell can fit 50 mm diameter silicon wafers. The sample dimensions should be ~51x14mm2.  



Zetasizer Nano (Nano ZS, Malvern) particle analyser combines measurements of particle size (0.6nm to 6μm) and zeta potential (size range for the measurements is from 5nm to 10μm.  The instrument has a unique feature of temperature controlled measurements. The allowed temperature control ranges from 0 to 90C with 0.1C precision. The instrument uses a 633 nm laser. Minimum sample volume is 1 mL.


Waters GPC-HPLC Breeze 2 system with RI detector

Molecular weight of polymers can be characterized (250 Da 80,000 Da) as well as Mw/Mn distributions.   

Optical Tensiometer

Theta Lite Optical Tensiometer TL100 (Biolin Scientific) is a compact computer controlled video based instrument for the measurement of contact angles and surface free energy (0...180 0.1, 0.01...999 mN/m 0.01 mN/m) In surface free energy calculations, data from Sessile Drop experiments is utilized to calculate the surface free energy of the solid. The available drop profiles are: sessile drop, pendant drop, meniscus, and reverse pendant drop. Advancing and receding contact angles can also be studied if dispensing the liquid manually. Maximum sample size: W unlimited x L200 x H50 mm



A Bruker FT-IR spectrometer (Vertex 70) is equipped with a narrow-band mercury cadmium telluride detector. The internal compartment of the FTIR spectrometer is purged with dry nitrogen to eliminate interference of water vapors. The technique allows for monitoring of chemical composition of films (on KBr pellets), powders (in KBr), and liquids.


ATR-FTIR (Attenuated Total Reflection Fourier Transform Infrared Spectroscopy)

A Bruker ALPHA ATR-FTIR spectrometer allows for fast surface analyses of films on silicon wafers; powders; and liquids.
