The phrase "accumulation and diffusion of" is correct and usable in written English.
It can be used in contexts discussing the gathering and spreading of information, resources, or knowledge.
Example: "The accumulation and diffusion of scientific knowledge are essential for technological advancement."
Alternatives: "gathering and spreading of" or "collection and distribution of".
Country-specific institutional features support or impede the accumulation and diffusion of knowledge between the scientific and industrial communities.
Precise transcript distribution in the syncytium is recovered via straightforward spatiotemporal averaging, i.e., accumulation and diffusion of transcripts during nuclear cycles, without regulatory feedback.
Such a small chamber size enabled rapid accumulation and diffusion of cell-secreted cytokines and, therefore, acutely reducing the volume and incubation time required for the target analyte binding to the LSPR sensing surface.
This observation suggests that multiorgan accumulation of H2S and diffusion of exogenously released H2S from the bacterial flora are both needed to establish the severe metabolic impairment and the fatal clinical course of ETHE1-less mice and humans.
Alternatively, the other one was that the intracellular drug accumulation and diffusion played a main role.
The model includes external mass transfer, pore volume accumulation and diffusion, adsorption using nonlinear isotherms, and surface diffusion.
But the origin and diffusion of religion, like the origin and diffusion of music, laughter, and xenophobia, reside in a largely irretrievable evolutionary past.
Obviously, resources devoted to the development and diffusion of driverless technologies are finite.
The mission of the Smithsonian Institution is the increase and diffusion of knowledge.
The lipid contents of intracellular components determine the extent of lipophilic compound accumulation, and the diffusion rate is related to the concentration gradient established between cell walls and organelles inside cells.
However, it should be noted that crystallization of such impure material must involve accumulation of impurities and diffusion over increasingly longer distances as crystallization progresses (rather than forming a supersaturated/supercooled melt that eventually will be glassy).
