The phrase "are randomly oriented" is correct and usable in written English.
It can be used to describe the arrangement or positioning of objects or elements that lack a specific direction or alignment.
Example: "The molecules in the gas phase are randomly oriented, allowing for greater freedom of movement."
Alternatives: "are haphazardly arranged" or "are randomly positioned".
The structural plasticity of α-actinin-2 has implications for not only its regulation but also for actin filament binding both in muscle and nonmuscle isoforms, where actin filaments are randomly oriented, requiring ABDs to adopt variable orientations.
As shown in Figure 3a, SiO2 NTs are randomly oriented, and a selected area EDS mapping was performed on the region within the yellow box.
The grains are stacked such that they share a common direction but are randomly oriented with respect to that axis.
The morphology analysis shows that MWCNT and SCF are randomly oriented in the composites.
Moreover, the analysis revealed that branches are randomly oriented with respect to the bacterial surface.
The pores' cross-sections are randomly oriented (cusp-shaped) hypotrochoids, so the material is isotropic in the plane of deformation.
Clearly, if the division planes in a cell mass are randomly oriented and individual cells expand uniformly, the tissue will enlarge as a sphere.
The term irregular dense fibrous tissue is applied to sites where the collagen bundles are randomly oriented and interwoven, as in the dermis of the skin and the capsules of joints.
In the case of a bi-layer stack, produced by double transfer of two graphene layers, the layers are randomly oriented and decoupled with respect to each other.
Single crystal diamond can easily be polished by choosing a direction of easy abrasion, but polishing a PCD imposes serious difficulties as the grains are randomly oriented.
This approach assumes that donor and acceptor fluorophores are randomly oriented, but do not rotate during their excited state (static regime).
