We observe diffusion in nature and in our technology on a daily basis, but seldom stop to think about the physical process behind the application. Without understanding diffusion, we could not have many breakthroughs in environmental and medical technologies.

Please research a technology involving diffusion, osmosis, or dialysis and present information a well written post about this technology and how it benefits humanity, with at least two internet sources. List which physical principle or principles are utilized, and if any diffusion coefficient can be determined for your example from our book or internet sources. If determining the diffusion coefficient is not possible, describe how this process would change if a different fluid or difference substance were used.

Discuss how this method is being used today and discuss any potential future use. Please comment appropriately on two other discussion posts, either offering additional information or reaction to the technology post.

Possible technologies include but are not limited to: Dialysis for Kidney Disease Reverse Osmosis for Water Purification Diffusion Chamber for Growing Microbial Cultures Gaseous Diffusion for Uranium Separation Oxygen-Diffusing Enhancing Compounds Bubble-Diffusion Humidifier Radial Immunodiffusion Technology Dissolved Oxygen Sensors (Membrane Type)
