Project Description
This Eduzendium project is a term project in lieu of a term paper and class presentation. Students collaborate in groups of three to generate encyclopedia articles related to bioseparation, also called downstream processing. Each student has primary responsibility for one article and serves as a reviewer for two more articles. In addition to writing and reviewing, we are developing skills in critical reading of scientific literature and in preparation of images to enhance the articles.
What We'll Be Working On
The following is a list of articles that BEE 4640 community will be working on during the Fall 2010 semester. These articles will be closed to editing by other citizens until after the conclusion of the course, though we would sincerely appreciate any citizen's contributions in the form of comments, suggestions or questions added to the articles' talk subpages.
New Articles
Filtration [r]: The separation of solid particles from a fluid in which they are suspended, by passing the fluid through a porous barrier which retains most or all of the particles. [e]
- Adsorption [r]: The attachment of molecules of gas, liquid, or dissolved solids to a surface, usually by weak non-covalent bonds. [e]

- Precipitation (chemistry) [r]: The conversion of a dissolved substance to solid particles in a solution, either by chemical reaction or by environmental manipulations e.g. cooling which render the substance insoluble. [e]
Centrifuge [r]: A device which separates particles or droplets suspended in a liquid based on their relative densities,using centrifugal force generated by spinning the sample rapidly around a fixed axis. [e]
- Crossflow filtration [r]: Add brief definition or description
Your article has been created. To create the metadata for this article in course-specific format, please
- Liquid extraction [r]: A process for separating components of a solution by exploiting differences in their solubility in, or affinity for, a solvent immiscible with the initial solution. [e]
- Electrophoresis [r]: A separation process in which charged molecules or particles in aqueous solution are separated from each other according to their relative velocity in an electric field. [e]

- Chromatography [r]: Chemical purification process that separates substances based on differing affinities for other substances. [e]
