This simplified method can be applied to high concentrations of vanadium ions. Three cation exchange membranes were studied. The logarithmic value of the selectivity coefficient was linearly dependent on the molar fraction of vanadium ions in solution. The diffusion coefficient of vanadium ions decreased with decreasing water content. The membrane with the lowest diffusion coefficient was selected as a battery separator and showed the lowest capacity loss of the studied membranes.}, issn = {0736-6299}, publisher = {Taylor \& Francis}, url = {http://www.informaworld.com/10.1080/07366290802674614} } @ARTICLE{Chieng1992, author = {Chieng, S.C. and Kazacos, M. and Skyllas-Kazacos, M.}, title = {Modification of Daramic, microporous separator, for redox flow battery applications}, journal = {Journal of Membrane Science}, year = {1992}, volume = {75}, pages = {81--91}, number = {1-2}, month = dec, issn = {0376-7388}, keywords = {Daramic, microporous separator, redox flow cell and battery}, owner = {schwan}, timestamp = {2009.11.30}, url = {http://www.sciencedirect.com/science/article/B6TGK-43S71CR-7K/2/06f90d391c0eff0ff5df3f282ad5fe28} }" On Fri, 2009-12-11 at 15:37 +0100, Gustaf Rydevik wrote: > > > On Fri, Dec 11, 2009 at 3:04 PM, Schwan <s.s.hosse...@utwente.nl> > wrote: > Thanks, but how should I put the citation inside a data frame? > > data.frame(first txt file, second txt file...) > plot (what should I insert here????) type="p" > > And how should I load the txt files anyway inside the frame? > > > > > Can you give an example of a couple of text files?
