Diffundeeruvad
Diffundeeruvad is a term that appears in a small subset of diffusion literature to describe diffusion-like transport processes that depart from classical Fickian diffusion. The word seems to be a neologism formed from the root diffuse with a suffix intended to indicate ongoing or processual action; there is no universally accepted definition or standard usage in mainstream physics or chemistry.
Definition and characteristics: Diffundeeruvad typically refers to systems where the effective diffusion coefficient depends on time,
Contexts and examples: Observations are reported in porous media, fractured geological samples, gels and polymer networks,
Relation to other terms: The concept overlaps with established ideas of anomalous diffusion, non-Fickian diffusion, and
Applications and implications: Understanding diffundeeruvad phenomena is relevant for modeling contaminant transport in soils, drug delivery
