The phrase "align perpendicularly" is correct and usable in written English.
It can be used in contexts involving geometry, design, or any situation where objects need to be positioned at right angles to each other.
Example: "To ensure stability, the beams must align perpendicularly to the foundation."
Alternatives: "position at right angles" or "set at perpendicular angles".
Also found at this domain interface are two anti-parallel β-strands in the BC loop that align perpendicularly to the core fold of the C-domain (Fig. 1b).
X-ray diffraction patterns show that macromolecular chains tend to align perpendicularly to the deformation direction for the slowest analysed strain rates and in parallel to the deformation direction for the highest rates.
The advantage of a tapered bottom was that these structures allowed FtsZ-mts to align perpendicularly to the length axis of the compartments.
The smectic layer was aligned perpendicularly to the lamellar interface.
In some situations, more often in polar than in temperate ice, the hexagonal axes are aligned perpendicularly to the plane of foliation.
Currently, the performance of spreaders is assessed by determining the transverse distribution using a row of collection trays aligned perpendicularly to the driving direction.
The hierarchical lindgrenite particles are hollow and prickly spheres, which are comprised of numerous small crystal strips that are aligned perpendicularly to the spherical surface.
Arromanches became one of two assembly points for the Mulberry artificial harbours, temporary jetties of prefabricated concrete supports, steel spans, and floating piers that were towed across the channel in sections and aligned perpendicularly to the beach.
The measurement technique of the radiometer under study is based on a porous disc aligned perpendicularly to a flowing gas stream, while one of its faces is exposed to the heat flux to be measured.
X-ray diffraction and transmission and scanning electron microscopies all indicate that when CNTs are well dispersed, crystalline spherulites are not present and remarkably crystalline lamellae grow aligning perpendicularly to the surface of the nanotubes.
After the stress fibers had aligned perpendicularly and the JNK activity had subsided, a 90° change in the direction of cyclic uniaxial stretch reactivated JNK, and this activation again subsided as stress fibers became re-oriented perpendicular to the new direction of stretch.
