TEMPO-mediated oxidation of cellulose III
TL;DR: Various cellulose samples converted into cellulose III by two different ammonia treatments were reacted with catalytic amounts of 2,2,6,6-tetramethylpiperidine-1-oxyl radical, sodium hypochlorite, and sodium bromide in water and a relationship between oxidation conditions and cellulose primary hydroxyl groups accessibility was directly established.
Journal ArticleDOI
Morphological investigation of nanoparticles obtained from combined mechanical shearing, and enzymatic and acid hydrolysis of sisal fibers
Gilberto Siqueira,Sandra Tapin-Lingua,Julien Bras,Denilson Da Silva Perez,Alain Dufresne,Alain Dufresne +5 more
TL;DR: This investigation proved that the distinction between MFC and whiskers to describe such cellulose nanoparticles is not sufficient, and the usefulness of the enzymatic treatment for cellulose nanocrystals production is indicated.
Journal ArticleDOI
Pullulan–nanofibrillated cellulose composite films with improved thermal and mechanical properties
Eliane Trovatti,Susana C. M. Fernandes,Laurent Rubatat,Denilson Da Silva Perez,Carmen S. R. Freire,Armando J. D. Silvestre,Carlos Pascoal Neto +6 more
TL;DR: In this paper, the effect of the addition of glycerol, as a plasticizer, on the properties of the bionan composites was evaluated and the resulting materials were characterized in terms of morphology, thermal stability, crystalline structure and mechanical properties.
Journal ArticleDOI
Mechanical properties of natural rubber nanocomposites reinforced with cellulosic nanoparticles obtained from combined mechanical shearing, and enzymatic and acid hydrolysis of sisal fibers
Gilberto Siqueira,Sandra Tapin-Lingua,Julien Bras,Denilson Da Silva Perez,Alain Dufresne,Alain Dufresne +5 more
TL;DR: It was shown that the pre-enzymatic hydrolysis treatment of bleached sisal pulp helps the preparation of well individualized rod-like nanocrystals and both tensile tests and dynamic mechanical analyses showed improved stiffness for all nanocomposites.
Journal ArticleDOI
How inorganic elements of biomass influence char steam gasification kinetics
Capucine Dupont,Sylvain Jacob,Khalil Ould Marrakchy,Céline Hognon,Maguelone Grateau,Françoise Labalette,Denilson Da Silva Perez +6 more
TL;DR: In this article, the influence of biomass type on char steam gasification kinetics was investigated and three different types of rate evolution versus conversion could be observed depending on the ratio K/(Si+P) and were correlated with the ash surface composition after gasification.
