The 123 pages that link to Diffusion, each with the reason it gives.

• Chemical potentialRelated: Chemical-potential gradients, rather than concentration gradients alone, determine diffusion in nonideal systems.

• OsmoregulationNarrower topic: Osmotic balance depends on solute movement as well as water movement.

• OsmosisCompared with: Unlike general diffusion, osmosis specifically concerns water crossing a selectively permeable membrane.

• ConvectionCompared with: Diffusion spreads heat without the organized bulk flow central to convection.

• Brownian motionRelated: Einstein derived Brownian particle diffusion from molecular impacts.

• ConcentrationRelated: A concentration gradient drives diffusion until the gradient diminishes.

• Materials scienceRelated: Atomic diffusion enables many transformations during processing and service.

• GillsNarrower topic: Gills exchange oxygen and carbon dioxide through concentration-driven diffusion across thin tissue.

• Heat equationNarrower topic: The heat equation is the standard continuum model for diffusion over time.

• TranspirationNarrower topic: Water vapor moves from humid leaf air spaces toward drier surrounding air by diffusion.

• DissolutionRelated: Diffusion carries dissolved particles away from a dissolving surface, sustaining concentration gradients.

• PassivationRelated: A dense passive film limits the transport of ions and molecules needed for continued corrosion.

• VentilationCompared with: Ventilation is bulk flow, whereas gases cross respiratory surfaces mainly by diffusion.

• AtomismRelated: Random microscopic motion produces this visible large-scale mixing.

• Cutaneous respirationNarrower topic: Oxygen and carbon dioxide cross the body surface down their concentration gradients.

• Random walkRelated: Random microscopic motion can generate macroscopic diffusion.

• SinteringRelated: Atomic diffusion transports material across particle contacts and drives bonding during sintering.

• ChemotaxisRelated: Diffusion often creates or disperses the gradients that cells follow.

• HemodialysisRelated: It moves many dissolved wastes from blood into dialysate across the dialyzer membrane.

• MicrofluidicsRelated: It often replaces turbulence as the main way adjacent streams mix.

• DyeRelated: Dye molecules diffuse into a material before becoming trapped or bound within it.

• Gas exchangeNarrower topic: Oxygen and carbon dioxide cross most respiratory surfaces down their partial-pressure gradients.

• PegmatiteRelated: Diffusion rates help constrain how large crystals can grow in a limited volume of melt.

• Tracheal systemNarrower topic: Oxygen and carbon dioxide cross between tracheoles and tissues down concentration gradients.

• Amphibian skinNarrower topic: Gases and dissolved substances cross amphibian skin down concentration gradients.

• Fick's laws of diffusionNarrower topic: Fick's laws provide a mathematical description of this broad transport process.

• HydrationRelated: Water often spreads through a material by diffusion during hydration.

• Respiratory systemRelated: Oxygen and carbon dioxide cross respiratory surfaces down their partial-pressure gradients.

• Book lungRelated: Oxygen and carbon dioxide cross the thin surfaces of book-lung plates by diffusion.

• AdvectionCompared with: Diffusion spreads a quantity through microscopic mixing, unlike advection by bulk motion.

• BatteryRelated: Transport of ions and reactants can limit battery power and charging speed.

• Fish gillNarrower topic: Oxygen and carbon dioxide cross gill surfaces down their concentration gradients.

• Ostwald ripeningNarrower topic: It is the transport process that redistributes material among droplets.

• Point defectNarrower topic: Mobile vacancies and interstitials provide pathways for atomic diffusion in crystals.

• BriningRelated: Salt ions gradually spread from the brine into the food.

• Concentration gradientRelated: Random molecular motion produces net transport down a concentration gradient.

• Glomerular filtrationCompared with: Filtration is driven chiefly by pressure, not by concentration gradients alone.

• Pressure gradientCompared with: Diffusion is driven by molecular concentration differences, not by pressure force alone.

• Surface areaRelated: Greater membrane area can increase the rate of exchange by diffusion.

• CytoplasmRelated: It moves small molecules through cytosol, though crowding and cell size can limit its reach.

• MetasomatismRelated: Diffusion redistributes dissolved components through minerals and along grain boundaries.

• Creep (deformation)Narrower topic: Atomic diffusion enables several creep mechanisms at elevated temperatures.

• DryingRelated: Moisture often must diffuse from a material's interior before reaching its surface.

• Isotope fractionationRelated: Lighter isotopic molecules generally diffuse faster, creating kinetic separation.

• MacerationRelated: Dissolved compounds move from plant tissues into the surrounding liquid down concentration gradients.

• QuenchingRelated: Rapid cooling restricts diffusion, suppressing transformations that require long-range atomic movement.

• AbsorptionRelated: After entering a material, absorbed particles often spread through it by diffusion.

• Interstitial fluidRelated: Many nutrients, gases, and wastes cross tissue spaces by diffusion.

• MarinadeRelated: Marinade compounds move into food mainly by diffusion, which is limited by time and distance.
