The isomeric non-gelator molecules 1- or 2-naphthoic acid (NA1, or NA2) were found to form two-component supramolecular gels with an amphiphilic gelator LHC18, and the NA2/LHC18 gel underwent shrinking at room temperature.

An efficient method of formation of the ordered fullerene C60 nanoaggregates in the volume of evaporating fullerene droplets in mixtures of two-component solvents (benzene and acetonitrile) on a flat substrate surface at room temperature is demonstrated. The specific physical-chemical mechanism of the synthesis of fullerene C60 aggregates in the volume of the evaporating droplet of solution, so called Ostwald ripening, according to which relatively large structures grow at the expense of smaller ones, has been proposed.

Annealing in a two-component supramolecular gel leads to a self-sorted network, which has significantly different mechanical properties to the as-prepared gels.
