Calcium carbonate thixotropic nanoheterogeneous systems with nanomicelle diameter of 7 to 30 nm are synthesized by a carbonation of reciprocal emulsions for calcium-hydroxide methanol-water solutions dispersed in toluene-oil phase with additives. The orientations of surfactants cause the carbonate crystal growth in preferred directions actuated effective self-organization of CO2 conversion and self-assembling of nanomicelle composition on a quantum level [1]. The cores of calcium sulfonate nanomicelles are characterized comparatively by maximal concentration of calcite phase and also a new phase which has reflexes in a region q=2.8-3.0 nm-1 (Figure, profiles 1 and 2) and may be corresponded to a stretched nanocluster carbonate polymorph of aragonite. But some interesting quantum effects for these sulphonate nanomicelles (see 1st abstract here too), the similar WAXS spectra in the region for atomic carbon nanostructures (profiles 3 and 4) and at last the fundamental question about coexistence of various polymorphic phases in one nanocore are indicated a high probability of different carbonaceous processes in the synthesis with possible electrostatic “emersion” of GO or CNT clusters at the intra-micelle nanointerfaces.
