Saccharification of Brazilian sisal pulp: evaluating the impact of mercerization on non-hydrolyzed pulp and hydrolysis products
(SPRINGERDORDRECHT, 2012-04)
Cultivation of sisal, a plant with a short growth cycle, is highly productive in Brazil. This work is part of extensive research in which sisal is valued. In these studies, sisal fibers are used in the preparation of ...
A physical organic chemistry approach to dissolution of cellulose: effects of cellulose mercerization on its properties and on the kinetics of its decrystallization
(ARKAT USA INC, 2011)
The effects of alkali treatment on the structural characteristics of cotton linters and sisal cellulose samples have been studied. Mercerization results in a decrease in the indices of crystallinity and the degrees of ...
Reproducing kernel Hilbert spaces associated with kernels on topological spaces
(CONSULTANTS BUREAU/SPRINGERNEW YORK, 2012)
We analyze reproducing kernel Hilbert spaces of positive definite kernels on a topological space X being either first countable or locally compact. The results include versions of Mercer's theorem and theorems on the ...

Cellulose swelling by protic solvents: which properties of the biopolymer and the solvent matter?
(SPRINGER, 2008)
The question posed in the title has been addressed by studying the swelling of celluloses at 20 C by twenty protic solvents, including water; linear- and branched-chain aliphatic alcohols; unsaturated aliphatic alcohols, ...
Tire rubber-sisal composites: Effect of mercerization and acetylation on reinforcement

Radiocarbon dating of the last glaciation in Peru
(Geological Society of AmericaUS, 1977-10)
In the Cordillera Vilcanota and the vicinity of the Quelccaya ice cap, near lat 14°S in eastern Peru, the last glaciation culminated sometime between about 28,000 and 14,000 B.P. Alpine glaciers were then only about half ...
Some aspects of acetylation of untreated and mercerized sisal cellulose
(Sociedade Brasileira de Química, 2010)
We report here on some aspects of the acetylation in LiCl/N,N-dimethylacetamide, DMAc, of untreated and mercerized sisal cellulose, hereafter designated as sisal and M-sisal, respectively. Fiber mercerization by NaOH ...
