A limit of displacive plasticity leading to a phase-transition path was reported for Si nanospheres [5] concluding that in ultrasmall structures

Thus, we report for the first time a CeO2/SiC core–shell system with tunable particle sizes through a miniemulsion technique, and demonstrate its use as a catalyst for the oxidation of methane.

In case of the surface functionalized PCS-Acr spheres (comonomer = acrylic acid), 3.5 mL of this PCS-Acr miniemulsion was added to an 0.1 M aqueous solution of 440 mg Ce(NO3)3·6H2O (Aldrich, 99%) and stirred overnight at RT. The PCS-nanospheres were destabilized by adding acetone, centrifuged and

The direction of motion of the nanoparticles is essentially fixed by the distance b between consecutive scan lines. Well-defined formulas are obtained in the case of rigid nanospheres and nanowires.
