Journal ArticleDOI
Raman spectroscopic study of glutaraldehyde-stabilized collagen and pericardium tissue
TL;DR: The results have shown that GA treatment causes an increase in water content of pericardium tissue and collagen, and different hydration levels and a more complex structure of intact tissue in comparison to collagen preparation strongly influence the formation of a GA cross-linking network.
Journal ArticleDOI
Molecular dynamics of itraconazole at ambient and high pressure.

TL;DR: DSC measurements yielded besides melting and glass transition observed during heating and cooling of both samples two further endothermic events at around T = 363 K and T = 346 K, which indicated that extra ordering in itraconazole is likely to occur.
Journal ArticleDOI
Tannic acid-stabilized pericardium tissue: IR spectroscopy, atomic force microscopy, and dielectric spectroscopy investigations.
Maria Jastrzębska,J. Zalewska-Rejdak,Roman Wrzalik,A. Kocot,Iwona Mróz,Bogdan Barwiński,A. Turek,Beata Cwalina +7 more
TL;DR: It was found that both relaxation processes were influenced by the TA-collagen interaction, and the relaxation process due to orientation of bound water supplemented by the fluctuation of collagen polar side groups.
Journal ArticleDOI
Dielectric studies on charge hopping in melanin polymer
TL;DR: In this paper, two main hopping distances, ∼1.5 and ∼3.6 nm, have been estimated, according to the spatial model of the molecular arrangement in melanin, and two relaxation regions attributed to the waterdependent hopping polarization have been found.
Journal ArticleDOI
Ab initio study of phenyl benzoate: structure, conformational analysis, dipole moment, IR and Raman vibrational spectra.
Roman Wrzalik,K. Merkel,A. Kocot +2 more
TL;DR: The theoretical results are discussed mainly in terms of comparisons with available experimental data, and good agreement between theory and experiment is obtained for the MP2, B3LYP and B3PW91 levels with basis sets including diffuse functions.
