Self-supported silver nanoparticles containing bacterial cellulose membranes
(Elsevier B.V., 2008-05-01)
Hydrated bacterial cellulose (BC) membranes obtained from cultures of Acetobacter xylinum were used in the preparation of silver nanoparticles containing cellulose membranes. In situ preparation of Ag nanoparticles was ...
Extraction of cellulose nanowhiskers from natural fibers and agricultural byproducts
In this work the feasibility of extracting cellulose from cotton, sisal and flax fibers, corn stover and rice husk by means of usual chemical procedures such as acid hydrolysis, chlorination, alkaline extraction, and ...
Biodegradation evaluation of bacterial cellulose, vegetable cellulose and poly (3-hydroxybutyrate) in soil
(Assoc Brasil Polimeros, 2015-03-01)
In recent years, the inappropriate disposal of polymeric materials has increased due to industrial development and increase of population consumption. This problem may be minimized by using biodegradable polymers, such as ...
CELLULOSE NANOCRYSTALS FROM BACTERIAL CELLULOSE
(Soc Brasileira Quimica, 2015-11-01)
Bacterial cellulose produced from Gluconacetobacter xilinus was used to produce cellulose nanocrystals by sulfuric acid hydrolysis. Hydrolysis was performed with 64% sulfuric acid at 50 degrees C with the hydrolysis time ...
Molecular dynamics simulation of the aqueous solvation shell of cellulose and xanthate ester derivatives
(John Wiley & Sons, Ltd., 2008)
Composite membrane of niobium(V) oxide and cellulose acetate: Preparation and characterization
(Academic Press Inc Jnl-comp SubscriptionsSan Diego, 1997)
Morphological evolution of curaua fibers under acid hydrolysis
Kinetics of autocatalytic acid hydrolysis of cellulose with crystalline and amorphous fractions
The acid hydrolysis of cellulose with crystalline and amorphous fractions is analyzed on the basis of autocatalytic model with a positive feedback of acid production from the degraded biopolymer. In the condition of low ...
