Notes
- "Xúc biến" is a specialized scientific term derived from Sino-Vietnamese roots ("xúc" meaning to touch/agitate, "biến" meaning to change). It is not used in everyday conversation but is common in fields like materials science, chemistry, rheology, and engineering.
- The phenomenon is often described in terms of a time-dependent shear thinning property.
