A high-powered concentration-gradient cathode material with an average composition of LiNi0.815Co0.15Al0.035O2 (LGNCAO) has been successfully synthesized by using spherical concentration-gradient Ni0.815Co0.15Al0.035(OH)2 (GNCA)as the starting material.
In the case of thermal treatment without a magnetic field, the spherical concentration inhomogeneities are distributed in a sample, mainly, chaotically, in contrast to thermomagnetic treatment, which orders the Cu2MnAl phase nanoparticles nucleation.
The clues come from globular clusters--spherical concentrations of up to millions of stars, orbiting the galactic center as self-contained neighborhoods.
At low concentration, spherical micelles form, whereas at high concentration, the formation of hexagonal, cubic, and lamellar liquid crystalline phases takes place [58].
Without CMC, the crystals appeared in the form of cylinder, while CMC addition changed the crystalline shape to be fusiform at the low concentration and spherical at the high concentration.
At certain concentrations, spherical nanoparticles of PPy formed and the thermal properties of the material were significantly enhanced.
For spherical droplets at concentrations that are usually observed in arc-evaporation coatings, the value of F decreases linearly, proportional to the droplet concentration and almost independent of droplet thermal conductivity for regularly experimentally encountered droplet materials.
Also, we observed some morphological changes in the CeO2 NPs treated cells such as at concentration 25 μg/mL few cells become spherical while at concentration 100 μg/mL the number of the spherical cells increased and many of them were detached from the surface of culture plate.
Another hypothesis proposed by Wang et al. [12] suggests that sucrose molecules form a kind of amphiphilic micelle compound under hydrothermal conditions, and as the concentration of this compound reaches a critical micelle concentration, spherical micelles develop.
Recently, Yu et al. [77] showed that aggregates' morphology of the amphiphilic G1 PAMAM dendrimer onto the mica substrate was seemingly spherical at low concentration and that semi-continuous films or network structure films were formed at high concentrations.
