Add to ORKGWe study (i) spontaneous phase separation and nematic self-assembly in gravity of synthetic clay particles in aqueous suspensions, and (ii) guided self-assembly into chainlike structures of polarized clay particles in oil suspensions (electrorheological behavior). Experimental tech-niques used are synchrotron X-ray scattering, rheometry and microscopy. We demonstrate that clays may be used as good model systems for self-assembled soft and complex matter, and we give examples of interconnected complex physical phenomena in such systems. Self-assembly in clays may have practical relevance for nano-patterning, properties of nanocomposites, and macroscopically anisotropic gels. 1 Introduction: Syntheti
