Controlled cellulose decomposition

Catalytic Decomposition of Cellulose under Biological Conditions.

1. The catalytic decomposition of undegraded cellulose in the form of cotton fibres is described with hydrogen peroxide at 0.4-0.04% (w/v) concentration in the presence of ferrous salts at pH3-5. 2. Complete solubilization of 5mg. of cotton fibres occurred in about 7 days in the presence of 0.4% hydrogen peroxide and 0.2mm-ferrous sulphate at the optimum pH4.2-4.3. 3. With 0.4% hydrogen peroxid...

The Decomposition of Cellulose by Soil Fungi*

Simultaneous cellulose conversion and hydrogen production assisted by cellulose decomposition under UV-light photocatalysis.

Photocatalytic conversion of cellulose to sugars and carbon dioxide with simultaneous production of hydrogen assisted by cellulose decomposition under UV or solar light irradiation was achieved upon immobilization of cellulose onto a TiO2 photocatalyst. This approach enables production of hydrogen from water without using valuable sacrificial agents, and provides the possibility for recovering ...

Regenerated cellulose for controlled oral drug delivery

The performance of regenerated cellulose (RC) films and capsules was investigated for their applications in oral controlled drug delivery. Regenerated cellulose films were prepared by non-solvent-mediated, phase inversion of native and depolymerized cotton linter solutions (methylolcellulose; cellulose dissolved in dimethyl sulfoxide/ paraformaldehyde solvent system) in water as well as by phas...
