When 10 spheres aggregated together, they stopped at a certain position just after the phase transition in horizontal pipe.
Many of the resulting spheroids were a mixture of GFP+ and GFP− cells, which is consistent with previous studies that showed that precursors can adhere to each other to form spheres and that smaller spheres can aggregate and eventually fuse to become a single larger sphere (Ladiwala et al., 2012).
A diverse range of products are obtained like sphere, spherical aggregate, irregular, micro rectangular platelet and octahedron.
When PS-b-PEO block copolymer solutions in tetrahydrofuran (THF) are treated with scCO2 at 70 °C for different times, PS-b-PEO copolymers first assemble into aggregated spheres; then aggregated spheres change into large compound micelles and finally evolve into vesicles.
When the initial distance was about 5.5 mm at the entrance of testing pipe section, the PNIPAM spheres could aggregate together after the phase transition and subsequently roll forward; but when the initial distance was as large as 8.5 mm, the distance became close at first during the phase transition and then far after the phase transition.
Here we communicate the generation of biomimetically grown apatite spheres from aggregated bioglass nanoparticles and the potential properties applicable for drug delivery and cell/tissue engineering.
When the cells were plated onto plastic, they did not form spheres, but aggregated to form 3D acinar-like spheroids when cultured on Matrigel, PCL, and PCL microwells, with the greatest aggregating potency being observed on the PCL microwells.
When surface growth stops, mature soot grows by agglomeration of these polydisperse spheres and aggregates before oxidation and condensation take over.
During the expansion stage (the fourth stage), two types of cells with distinct morphologies normally emerge, with one type being monolayer cells and the other sphere-like aggregates growing on top of the monolayer cells.
During nascent soot formation polydisperse spheres and aggregates are formed, attaining an asymptotic geometric standard deviation of 1.2 ± 0.01, in agreement with experiments in premixed, diffusion flames and wood combustion.
The atomic force microscopy (AFM) data [21 23] confirm randomly arranged individual C60 molecules with a diameter of ~0.7 nm and their bulk sphere-like aggregates with a height of 2 100 nm in C60FAS.
