The Chemistry Department and the Williams research group address the physical chemistry needs of the university, the State of Texas, and the general public through:
of quantum mechanics, spectroscopy, thermodynamics, and kinetics drawing material from various authors. (P.W. Atkins, J. Nibler, G Herzberg, T. Engel, P. Reid, D. Harris, M. Bertolucci, F. Cotton, and R. Drago).
using image processing, Hansen Sphere determination, process mapping, numerical modeling, non-linear optimization, multiple linear / step-wise regression, spectral deconvolution, gauge repeatability-reliability analysis, and molecular modeling (HSPiP, Minitab, ImageJ, Mathmatica, Excel, Gaussian, Hyperchem, and Discovery Studio).
- Hydrometry (temperature-controlled large-capacity)
- Tensiometry (temperature-controlled, interfacial, large-capacity)
- Contact Angle Analysis (Langmuir, Bikerman, and Drop Shape Analysis Methods)
- Viscometry (temperature-controlled, capillary and falling-ball)
- Chromatography (gas, liquid, and ion)
- Mass spectrometry (gas, solid desorption, and ion mobility)
- Calorimetry (bomb and solution)
- Digital microscopy (polarized visible and infrared)
- Spectroscopy (absorption-UVVIS, reflectance-UVVIS, micro-UVVIS, macro/micro-absorption-FTIR, macro/micro-reflectance-FTIR, micro-grazing-angle-reflectance-FTIR, macro/micro-attenuated-total-reflectance-FTIR, Raman, micro-Raman, laser-induced-fluorimetry, solution fluorimetry, 60Mhz NMR, and 300MHz NMR)
- Using short-turnaround 3-month (Jun – Aug), 6-month (Mar – Aug, Jun – Nov), 9-month (Dec – Aug, Jun – Feb), and annual research contracts and grants.
- Using a mixture of faculty, graduate students, exchange students, and undergraduate students.
