Morphology

diffusional = diffusion (transparent) = diffuse + ion + al

The adjective is formed in a standard way from diffusion plus -al, giving the meaning 'relating to diffusion'.

Etymology

The word diffusional comes from diffuse, made from the parts dis- ('apart') and fundere ('to pour'), so imagine something being 'poured out' in all directions. So, diffusional means 'relating to diffusion', the spreading or movement of particles.
