CELULOSE FIBROSA DO BAGACO DA CANA-DE-ACUCAR - AVALIACAO DA ACAO AGLUTINANTE/DESAGREGANTE EM COMPRIMIDOS CONTENDO FARMACO HIDROSSOLUVEL
(1993-12-01)
In this work, a fibrous cellulose obtained from the sugar cane bagasse was analysed about its binder/disintegrating action and about its interference degree in the dissolution rate ('in vitro') of active principles, when ...

Acetylation of cellulose in LiCl-N,N-dimethylacetamide: first report on the correlation between the reaction efficiency and the aggregation number of dissolved cellulose
(SPRINGER, 2011)
The acylation of three cellulose samples by acetic anhydride, Ac(2)O, in the solvent system LiCl/N,N-dimethylacetamide, DMAc (4 h, 110 A degrees C), has been revisited in order to investigate the dependence of the reaction ...
Acetylation of bacterial cellulose catalyzed by citric acid: Use of reaction conditions for tailoring the esterification extent
(Elsevier, 2016-11)
Bacterial cellulose (BC) nanoribbons were partially acetylated by a simple direct solvent-free route catalyzed by citric acid. The assay of reaction conditions within chosen intervals (i.e. esterification time (0.5–7 h), ...
Anti-E. coli cellulose-based materials
(Elsevier Science, 2019-06)
This work aimed to study Microcin J25(G12Y) (MccJ25(G12Y)) sorption to fibrous and microfibrillated cellulose (MFC) films for setting up anti-E. coli materials. The Freundlich model showed the best fit for both films, ...
Electrochemical investigations of Nb2O5/carbon materials from filter paper, microfibrillated and bacterial celluloses by sustainable reductive mineralization
(Pergamon-Elsevier Science Ltd, 2019-04)
Cellulose is an attractive reagent for the elaboration of C-containing materials, but here, we also considered it as an O-provider for preparing macro, micro and nano-fibrous Nb2O5/C composites by a new mineralization with ...
Isolation and characterization of cellulose nanofibers from argentine tacuara cane (Guadua angustifolia kunth)
(Tech Science Press, 2018-12)
New trends in the area of material improvement are the use of natural nano-charges from renewable biomass, improving the value and sustainability of our country’s natural products. Bamboo is widely used in many countries ...
Effect of different substrates on composting of poultry litter
(Sociedade Brasileira de Zootecnia, 2012-07-01)
The objective was to evaluate the differences between distinct types of litter material and their combinations in the dynamics of degradation on the organic matter fractions and the quality of the final compound. The ...
