Binary Mutual Diffusion Coefficients of Isoniazid Aqueous Solutions at (298.15 ...
Ribeiro, Ana C. F.; Santos, Ana C. G.; Lobo, Victor M. M.; Veiga, Francisco J. B.; Cabral, Ana M. T. D. P. V.; Esteso, Miguel A.; Ortona, OrnellaBinary mutual diffusion coefficients measured by the Taylor dispersion method in two different laboratories (University of Naples, Federico II, Italy, and University of Coimbra, Portugal) are reported for aqueous solutions of isoniazid at concentrations from (0.000 to 0.100) mol·dm−3 and at two temperatures (298.15 and 310.15) K. The hydrodynamic radii for the isoniazid in aqueous solution are calculated from t...
Some Transport Properties of γ-Cyclodextrin Aqueous Solutions at (298.15 and 31...
Ribeiro, Ana C. F.; Santos, Cecília I. A. V.; Valente, Artur J. M.; Ascenso, Osvaldo S.; Lobo, Victor M. M.; Burrows, H. D.; Cabral, Ana M. T. D. P. V.Values of binary mutual diffusion (interdiffusion) coefficients, obtained by using the Taylor dispersion method, for aqueous solutions of γ-cyclodextrin in the concentration range from (0.002 to 0.010) mol·dm−3 and temperatures (298.15 and 310.15) K are reported. From these experimental results, the hydrodynamic radius values for the γ-cyclodextrin are estimated. Also, the measured diffusion coefficients are us...

Intramolecular Cycloaddition of Imines of Cysteine Derivatives
Cabral, Ana M. T. D. P. V.; Gonsalves, António M. d'A. Rocha; Melo, Teresa M. Pinho eAzomethine ylides were generated from Schiffs bases of S-allylcysteine methyl ester and their intramolecular 1,3-dipolar cycloadditions were studied. These reactions led to the synthesis of thieno[3,4-b]pyrrole derivatives in good yield
