Mean distance of closest approach of ions: Lithium salts in aqueous solutions
Ribeiro, Ana C. F.; Lobo, Victor M. M.; Burrows, Hugh D.; Valente, Artur J. M.; Amado, Ana M.; Sobral, Abílio J. F. N.; Teles, Ana S. N.Numerical values for the mean distance of closest approach of ions, "a", for lithium salts in aqueous solutions are presented and discussed. These values were obtained from both experimental activity and diffusion coefficients, and estimated by using different theoretical approaches. ; http://www.sciencedirect.com/science/article/B6TGR-4RR1NKM-1/1/b8d3cdac33991c5424d567940bc0c3a6
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...
Binary Mutual Diffusion Coefficients of Aqueous Solutions of Sucrose, Lactose, ...
Ribeiro, Ana C. F.; Ortona, Ornella; Simões, Susana M. N.; Santos, Cecília I. A. V.; Prazeres, Pedro M. R. A.; Valente, Artur J. M.; Lobo, Victor M. M.Binary 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 lactose, sucrose, glucose, and fructose at various concentrations (0.001 to 0.1) mol·dm-3 and temperatures (298.15 to 328.15) K. The hydrodynamic radius and activation energy for the diffu...
