Experimental and Theoretical Study of Strong Low-Terahertz Absorption of Thymine

Zhang, W-D., A. Bykhovski, J. A. Deibel, and E. R. Brown.AbstractThe absorption coefficient of a nucleobase-thymine-in powder form was measured with terahertz spectroscopy in both frequency- and time-domain experiments. For frequencies below 3 THz, a strong signature...

Mathematical Modelling of Liquid Transport in Swelling Pharmaceutical Immediate Release Tablets

Markl, D., Yassin, S., Wilson, D. I., Goodwin, D. J., Anderson, A., Zeitler, J. A.AbstractOral dosage forms are an integral part of modern health care and account for the majority of drug delivery systems. Traditionally the analysis of the dissolution behaviour of a...

Characterization of the Pore Structure of Functionalized Calcium Carbonate Tablets by Terahertz Time-Domain Spectroscopy and X-Ray Computed Microtomography

Markl, D. ; Wang, P. ; Ridgway, C. ; Karttunen, A. P. ; Chakraborty, M. ; Bawuah, P. ; Zeitler, J. A.AbstractNovel excipients are entering the market to enhance the bioavailability of drug particles by having a high porosity and, thus, providing a rapid liquid uptake...

Terahertz spectroscopy and solid-state density functional theory calculations of structural isomers: Nicotinic acid, isonicotinic acid and 2-picolinic acid.

Ding, L., Fan, W. H., Chen, X., Chen, Z. Y., Song, C.AbstractWe report, for the first time to our knowledge, the terahertz (THz) spectra of isonicotinic acid and 2-picolinic acid. The distinct THz spectral differences among these two isomers and nicotinic acid have...
