Cellulose sponge

Sintering has been used to produce a porous polytetrafluoroethylene (16). Cellulose sponges are the most familiar cellular polymers produced by the leaching process (123). Sodium sulfate crystals are dispersed in the viscose symp and subsequently leached out. Polyethylene (124) or poly(vinyl chloride) can also be produced in cellular form by the leaching process. The artificial leather-tike materials used for shoe uppers are rendered porous by extraction of salts (125) or by designing the polymers in such a way that they precipitate as a gel with many holes (126).

Place a gel, loaded with samples, on a block of reusable ice between two reservoirs containing electrode buffer. Connect the reservoirs to the power supply using electrical leads fitted with male banana plugs. Be sure that the entire bottom of the gel mold is in contact with the ice so that cooling is even. Orient the gel so that the wicks are closest to the negative pole (black or cathode). Use cellulose sponges or Handiwipes (available in most gro-... 

Cellulose sponge is a cavity foam cellulose-based sponge available in sheets and thin bands, used to absorb at small sites in surgery. The material is not radiopaque and has a tendency to lose particles additional precautions must therefore be taken if such surgical use is contemplated. 

Sales Directly into Wholesale and Retail Trade Channels. Comparatively few chemical products are sold directly into wholesale or retail trade channels. A few examples are household insecticides, some fertilizers, soil conditioners, antifreezes, and cellulose sponges. 

Rambo et al. (2006) produced highly porous biomorphous alumina scaffolds by pyrolysis of natural cellulosic sponges that afterwards were infiltrated by aluminium vapour, and subsequently oxidised and sintered. These alumina scaffolds were immersed in highly supersaturated SBF for 4 days to yield a thin (2 pm) calcium phosphate layer with a Ca/P ratio of 1.62, indicating the formation of a Ca-deficient bone-like hydroxyapatite layer. Kim et al. (2003a) had performed similar work on biomorphous zirconia scaffolds previously. 

Most of the techniques in current use are derived from the original method described by Meier, Schuler and Desaulles in 1950 . When pellets of cotton-wool, cellulose sponge or similar material are implanted subcutaneously into the abdomen of the rat and left for 7 days, granulation tissue forms around and into the pellets. After 7 days the animals are killed and the pellets, together with the granulation tissue, are removed and dried to...

Mathis and Smith (1992) pioneered an excellent trap experiment technique for studying the responses of freshwater littoral fishes to chemical alarm cues. Mathis and Smith s experiment, and most of those that followed, used Gee s Improved Miimow Traps, roughly cylindrical wire enclosures (43 cm length x 22 cm diameter) with a funnel located at each end leading into the trap. Cube-shaped artificial cellulose sponges saturated with the experimental treatment were threaded onto stainless steel wire, and...
