Colloids and geochemistry Colloids are generally described as small, sub-micron particles, too small to settle in natural groundwater flow conditions, but sufficiently large to behave significantly different from e.g. aqueous species in solution. They are often considered as rapid carriers for otherwise insoluble radioactive elements, and therefore potentially decrease the effective barrier function of the geological rock surrounding a waste repository My Ph.D. thesis is about colloids, geochemistry and transport modelling. Auxilary scientific software JPlot is software for displaying scientific graphs. JPlot runs on any java-enabled platform. If you think that JPlot is useful for you or your institute and you are interested in helping with the development, drop us an E-mail or join the JPlot mailing list.
