Oxidation of cellulose in pressurized carbon dioxide [PDF]

open access: yes, 2009
This work presents first results upon oxidation of type II cellulose by nitrogen dioxide dissolved in carbon dioxide at high pressure. This reaction leads to oxidized cellulose, a natural-based bioresorbable fabric used for biomedical applications.

Nuclease p1 immobilized on deae cellulose [PDF]

open access: yesBrazilian Journal of Chemical Engineering, 2010
Effects of various factors, such as pH, ionic strength, glutaraldehyde concentration, enzyme amount and immobilization time, on enzyme activity were investigated. The immobilization conditions were optimized by orthogonal experiments. Characterizations of immobilized nuclease p1 were also evaluated.

HISTAMINE-LIBERATING ACTIVITY OF SERUM PROTEIN EXPOSED TO DEAE-CELLULOSE

open access: yes, 1967
Dog serum protein fractions prepared by chromatography on DEAE-cellulose produced an increase in local small-vessel permeability with distinct wheal formation when injected intracutaneously into the animal from which the whole serum was obtained.

Diethylaminoethyl cellulose (DEAE-C): applications in chromatography and organic synthesis [PDF]

open access: yes, 2020
The aim of this review is to point out the attention of the reader to the use of DEAE-C in organic reactions, possibly not only devoted to the preparation of heterocycles but potentially extending to other classes of organic compounds.
