Full size image It has been shown that the size, crystallinity, and the saturation magnetization (Ms) of magnetic nanoparticles can be increased by the hydrothermal method28,29,30. This technique is based on the Ostwald ripening mechanism in which the larger particles grow at the expense of the...

The transport of SBUs or/and molecular precursors from the liquid phase to the seeds finalizes the crystallization of the material, which can subsequently undergo Ostwald ripening, resulting in larger crystals. Simultaneously, more elementary mechanisms, such as growing from oligomers or pre-formed ...
Coarsening of QDs due to coalescence and Ostwald ripening was investigated by atomic-force and scanning electron microscopy. Ellipsoidal QDs prolated in [010] and oblated in [001] directions have been grown. Elongation ratios for the ellipsoidal QDs were measured in all three directions. It is ...
The phenomenon of Ostwald ripening is then discussed in terms of the MDP, and a novel formulation is developed based on the concept of an interaction matrix, the elements of which are Ewald sums. The formal relationship of these interaction matrix elements to Madelung's constant is discussed, ...

Besides, it has been shown that at high solid fraction, the Ostwald ripening mechanism plays a prominent role in the coarsening phenomenon in comparison with the coalescence mechanism. Grains can rotate and arrange low misorientation with each other at high liquid contents, therefore low energetic ...
