Metallic fibers, description

A wide variety of filters are available for the cell recovery. There are generally two major types of filters pressure and vacuum filters. The detailed descriptions of those filter units can be found in Chemical Engineers Handbook (Perry and Chilton, 1973). The two types of filters most used for cell recovery are the filter press and rotary drum filters. A filter press is often employed for the small-scale separation of bacteria and fungi from broths. For large-scale filtration, rotary drum filters are usually used. A common filter medium is the cloth filter made of canvas, wool, synthetic fabrics, metal, or glass fiber. 

The term vapor grown carbon fiber (VGCF) is an International Union of Pure and Applied Chemistry (lUPAC) recommendation and Tibbetts [1] believes that this term has won general acceptance for the class of material where a carbonaceous gas, in the presence of a small metal particle acting as a catalyst, forms a carbon filament. However, Dresselhaus and co-authors [2] use the term CCVD filament in their book, which stands for catalytic chemical vapor deposition and is certainly more descriptive of their mode of preparation, but is, unfortunately, not the generally accepted term.
