The phrase "approximately spherical shape" is correct and usable in written English.
It can be used when describing an object that is nearly round but not perfectly so.
Example: "The planet's approximately spherical shape allows it to maintain a stable orbit around the sun."
Alternatives: "nearly round form" or "roughly spherical appearance."
These images show that the nanocrystals have approximately spherical shape and are well dispersed without aggregation.
A porosity is usually small in size, typically less than 100 μm with an approximately spherical shape, as shown in Fig. 2 by arrows.
The amount of this slip can be estimated by considering a situation well after the recombination event, when the resulting loop has approximately spherical shape with radius R. The slipped area in the primary slip plane is then πR2, and the area in the cross slip plane is, on average, Rycs/2.
The Ni NPs were initiated from an approximately spherical shape and a perfect local fcc structure.
Pure ZnO and Ta-doped ZnO nanoparticles are approximately spherical shaped with the dispersive diameters of 10 60 nm.
Small fragmented mitochondria are often seen to have a spherical shape and the fusion of two small spherical mitochondria may produce a mitochondrion that itself has an approximate spherical shape.
To calculate the 3-dimensional plume volume produced by CRF 500 ng microinjections, we assumed a roughly spherical shape and calculated the inner intense sphere to contain a volume of approximately 0.06 mm, and the outer sphere to contain a volume of approximately 0.38 mm.
Micelles are approximately spherical in shape but its other shapes such as ellipsoids, cylinders, and bilayers are also possible.
It must be mentioned that nanoparticles are approximately spherical in shape as observed in TEM images represented in Fig. 2.
The size of the Au@GON NPs, approximately spherical in shape, is 60 ± 15 nm with 2 3 nm GON shell thickness.
One-hundred nanometer PMMA dust flames with a nominal concentration of 450 g/m3 were approximately spherical in shape and propagated continuously after ignition at different ignition delay times.
