Mean distance of closest approach of ions: Sodium salts in aqueous solutions
Ribeiro, Ana C. F.; Esteso, Miguel A.; Lobo, Victor M. M.; Burrows, Hugh D.; Amado, Ana M.; Costa, António M. Amorim da; Sobral, Abílio J. F. N.The estimation of numerical values for the mean distance of closest approach of ions, a, of sodium salts in aqueous solutions, determined from activity and diffusion coefficients, and also from different theoretical approaches, is presented and discussed. ; http://www.sciencedirect.com/science/article/B6TGR-4JCCFW7-1/1/45bf32523013b068b5040514add5505a
Para-halogenated benzaldehyde molecules included in cyclodextrins: a combined s...
Ribeiro-Claro, Paulo J. A.; Costa, António M. Amorim da; Vueba, Manuel L.; Pina, M. Eugénia; Amado, Ana M.The inclusion complexes of 4-X-benzaldehyde guests (X = F, Cl, Br) in alpha-, beta-and gamma-cyclodextrins (alphaCD, betaCD and gammaCD) were prepared and characterized by means of thermogravimetry, differential scanning calorimetry (DSC) and vibrational spectroscopy. The stoichiometry of the inclusion complexes ranges from 2:1 to 1:2, depending on the cavity size of the host. Sensitive vibrational modes such a...
