Modern NMR spectroscopy of proteins and peptides in solution and its relevance to drug design
(Kluwer Academic Publishers; ESCOM Science Publishers B.V. ; Springer Science+Business Media, 1993-12)
The knowledge of the three-dimensional (3D) structures and conformational dynamics of proteins and peptides is important for the understanding of biochemical and genetic data derived for these molecules. This understanding ...
Vibrational spectra, assignments and normal coordinate analyses for crystalline zirconium tetrachloride and tetrabromide
(Elsevier, 1981)
Raman and far-IR spectra have been obtained of crystalline ZrCl4 and ZrBr4. The observed frequencies have been interpreted on the basis of the C2h symmetry of the Bravais unit cell and have been subjected to a normal ...
Is cytochrome aa3 from thermus thermophilus a single subunit oxidase?
(Elsevier, 1983)
A reliable procedure has been developed for the purification of the cytochrome c1aa3 complex from the plasma membrane of T. thermophilus. The ratios heme C:heme A:Fe:C were found to be 1:2:3:2 confirming previous results, ...
The toughening of polyamide-6 by brominated poly(isobutylene-co-p-methylstyrene): fracture and toughening mechanisms
(Elsevier, 1993-11)
A study on the toughening of polyamide-6 (PA-6) with a new elastomeric modifier, brominated poly(isobutylene-co-p-methylstyrene) (BrXP-50), was conducted. Morphological analyses and mechanical tests were combined to evaluate ...
The determinants of divalent/monovalent selectivity in anion exchangers
(Elsevier, 1983-04)
This research demonstrates that it is the distance of fixed-charge separation in the resin which is the primary determinant of divalent/monovalent selectivity. Anion resins, particularly acrylics and epoxies, with closely ...
