Here, sedimentation and size partitioning contribute to a very rich phase behavior including nematic and columnar phases. This suggests the application of the self-organizing tendencies of such mineral liquid crystals to obtain materials with very diverse nanostructures.}, number = {19}, journal = {Advanced Materials}, author = {Vroege, G.J. and Thies-Weesie, D.M.E. and Petukhov, A.V. and Lemaire, B.J. and Davidson, P.}, year = {2006}, pages = {2565--2568}, }
