Synthesis and Characterization of Chitosan-PHB Blends
(Sociedad Chilena de Química, 2002)
Wood capillarity and deacetylation during eucalyptus alkaline impregnation. Suphidity effects and comparison between transverse directions
(de Gruyter, 2013-01)
The relative ion transport capacity of wood, i.e., the Effective Capillary Cross Sectional Area (ECCSA), is determined in this work based on the analogy with the relation between the electrical conductivities of wood and ...
Synthesis and characterization of chitosan-PHB blends
(Soc Chilena QuimicaConcepcionChile, 2002)
Capacity of adsorption of Pb2+ and Ni2+ from aqueous solutions by chitosan produced from silkworm chrysalides in different degrees of deacetylation
(Elsevier Science BvAmsterdamHolanda, 2007)
Determining the Relation between the Proportion of the Amino Group and the Degree of Deacetylation of Chitosan.
Several methods such as elemental analysis or infrared spectroscopy technique (IR) have been already developed to determine the degree of N-acetylation, for chitin and chitosan. This paper proposed the potentiometric ...
Diffusion dynamics in Pinus sylvestris Kraft impregnation: Effect of deacetylation and galactoglucomannan degradation
(American Chemical Society, 2013-01)
During the impregnation stage of a Kraft cooking, dynamic changes occur in wood properties due to the alkali action. Particularly, its ion transport capacity, the effective capillary cross sectional area (ECCSA), is changed ...
Mechanical properties, hydrophilicity and water activity of starch-gum film: effect of additives and deacetylated xanthan gum
(Elsevier B.V., 2005-03-01)
The effect of deacetylated xanthan gum, additives (sucrose, soybean oil, sodium phosphate and propylene glycol) and pH modifications on mechanical properties, hydrophilicity and water activity of cassava starch-xanthan gum ...
