The phrase "a spherical structure" is correct and usable in written English.
It can be used when describing an object or entity that has a round, three-dimensional shape, often in scientific or technical contexts.
Example: "The scientists discovered a spherical structure in the center of the cell that plays a crucial role in its function."
Alternatives: "a round formation" or "a globular shape".
Thus, a spherical structure is obtained.
The swollen chains are likely to retain a spherical structure.
A spherical structure was previously observed, in 1923, in the cytoplasm of a species identified as P. sphaerophora from a termite identified as Rhinotermes nasutus in British Guiana9.
We hypothesized that the shape is more complex than originally believed, and cannot be accurately modeled as a spherical structure.
Here we report the self-assembly of a spherical structure that also contains 30 palladium ions and 60 bent ligands, but belongs to a shape family that has not previously been observed experimentally17.
When exploring design principles appropriate for dealing with the self-assembly of large numbers of components, Daishi Fujita et al. discovered a spherical structure with a topology not previously reported at the molecular level.
After treated with conc A, spherical structures accumulated in the RNAi-2 vacuoles but not the RNAi-2×RNAi-AtATG18a vacuoles.
As shown in Fig. 2, all samples exhibit a uniformly spherical structure with a narrow size distribution of 5 10 μm, which is beneficial to a contact between the active materials and electrode.
Other facilities include a small children's library, exhibition spaces, lecture halls, a school for information sciences and a planetarium, this last being a separate, spherical structure poised at one end of the vast outside plaza like an orbiting satellite.
The deposited Al atoms are arranged in a hexahedral structure at lower temperature, and a better Mg-core/Al-shell cluster with a nearly spherical structure is obtained at 150 K.
Cui et al. [104] fabricated a YS Si@C spherical structure at room temperature.
