Organic membranes are made using a diverse range of polymers including cellulose acetate (CA), polysulfone, polyvinylidene fluoride, polyethersulfone and polyamide. These are most commonly used due to their flexibility, and chemical properties. [4] Inorganic membranes are usually composed of sintered metal or porous alumina. They are able to be ...
The use of nanofiber webs as a filtering medium is well established. Due to the small size of the fibers London-Van Der Waals forces are an important method of adhesion between the fibers and the captured materials. Polymeric nanofibers have been used in air filtration applications for more than seven decades.
Nanocellulose is a term referring to a family of cellulosic materials that have at least one of their dimensions in the nanoscale.Examples of nanocellulosic materials are microfibrilated cellulose, cellulose nanofibers or cellulose nanocrystals.
Carbol fuchsin, carbol-fuchsin, carbolfuchsin, or Castellani's paint (CAS) is a mixture of phenol and basic fuchsin that is used in bacterial staining procedures. It is commonly used in the staining of mycobacteria because it has an affinity for the mycolic acids found in their cell membranes .

A nanofiber has two external dimensions in the nanoscale, with nanotubes being hollow nanofibers and nanorods being solid nanofibers. A nanoplate/nanosheet has one external dimension in the nanoscale, [ 20 ] and if the two larger dimensions are significantly different it is called a nanoribbon .
