The phrase "amorphous pattern" is correct and usable in written English.
It can be used to describe a shape or design that lacks a clear structure or form, often in artistic or scientific contexts.
Example: "The artist's latest work features an amorphous pattern that evokes a sense of fluidity and movement."
Alternatives: "shapeless design" or "formless arrangement".
All the polyimides showed amorphous pattern according to Wide angle X-ray diffraction measurements.
In XRD analysis crystalline pattern of pure LST was changed to amorphous pattern when converted to microparticles.
"Loop Nodes and Sweep Isolated Loop," from 1967, for example, one of Mr. Saret's "gang drawings" made with a fistful of colored pencils, describes an amorphous pattern of lines and shapes that could serve as a sketch for one of the sculptures.
As can be seen from the XRD patterns, the samples heat treated from 500°C to 550°C have an amorphous pattern, while that of the 575°C sample contains diffraction peaks of KNN with a highly amorphous phase, giving rise to the lowest transparency of this sample.
When genes that help regulate 3D growth are disrupted, cells at the base of moss shoots show amorphous patterns of cell division.
Purely abstract narratives include Sandy Gellis's "Spring in the Northern Hemisphere," 11 etchings with amorphous patterning made by natural forces acting on her etching plate, which was exposed to the elements.
The polyimide prepared from p-phenylene diamine was partial crystalline, whereas the others showed amorphous patterns in a WAXD study.
Introducing the bulky pyrene substituent into pentablock copolymer, the melting temperature was not observed and all pentablock copolymers showed amorphous patterns in wide-angle X-ray scattering (WAXS) due to decrease in the degree of crystallinity of polymer chain because of disturbing regular packing.
Immediately after formation, some of the NLP complexes revealed either amorphous patterns with no discernible crystalline peaks (Fig. 3A) or mono-calcium phosphate peaks (Fig. 3B).
For the small serum pellets obtained from control serum, amorphous patterns predominated (Fig. 6A, FBS-1), but infrequently, HAP crystals were also detected (Fig. 6F, HS-1).
In fact, samples that had initially shown only amorphous patterns and that had been washed and suspended in water alone at 4°C also showed conversion to HAP when examined two weeks later (not shown).
