Resumen:

About the improvement of the capabilities of SAXS 2 it is worthy to mention that there are excellent cells for control of sample environment available in the market. Some examples are the ones that allow for simultaneous control of temperature and humidity (GISAXS configuration), as well rotating cells for isotropic precipitating materials. Such cells open new opportunities, and solves common problems.

 

On more ambitious terms, the implementation of a Langmuir trough for grazing incidence SAXS (or reflectivity) and grazing incidence diffraction would be a long term project that is discussed time by time with Dr. Leide Cavalcanti.  In Argentina there is a well developed community of Langmuir trough users (about teen groups) which is interested in such an initiative. Nevertheless, because of the horizontal sample geometry of the liquid surface, the implementation would require so much modification and probably will need a dedicated beamline.
