Lignocellulosic nanofibers from triticale straw : the influence of hemicelluloses and lignin in their production and properties
Tarrés, Quim; Ehman, Nanci Vanesa; Vallejos, María Evangelina; Area, María Cristina; Delgado Aguilar, Marc; Mutjé, Pere (Elsevier, 2017-05-01)The present work aims to determine the influence of hemicellulose and lignin content in the production of lignocellulosic nanofibers (LCNF) from triticale straws. Triticale straws were digested and then gradually delignified, ... -
Nanocelulosa a partir de residuos agro y forestoindustriales
Ehman, Nanci Vanesa (Universidad Nacional de Misiones. Facultad de Ciencias Exactas, Químicas y Naturales. Secretaría de Investigación y Posgrado. Doctorado en Ciencias Aplicadas, 2019-03-14)El aprovechamiento de los residuos lignocelulósicos es un desafío actual que permite obtener productos de alto valor agregado a partir de un desecho típico agro o forestoindustrial. Esta estrategia evita que los residuos ...
