Journal ArticleDOI
Enzymatic hydrolysis combined with mechanical shearing and high-pressure homogenization for nanoscale cellulose fibrils and strong gels.
Marjo Pääkkö,Mikael Ankerfors,Harri Kosonen,Antti Nykänen,Susanna Ahola,Monika Österberg,Janne Ruokolainen,Janne Laine,Per Tomas Larsson,Olli Ikkala,Tom Lindström +10 more
TL;DR: Mild enzymatic hydrolysis has been introduced and combined with mechanical shearing and a high-pressure homogenization, leading to a controlled fibrillation down to nanoscale and a network of long and highly entangled cellulose I elements.
Book ChapterDOI
Comparison of model surfaces for cellulose interactions: elevated pH
TL;DR: In this paper, a colloidal probe atomic force microscopy technique has been used to measure interaction forces between cellulose and glass at normal and high pH, and the results showed that at low pH (5.5-6) the interaction at large separations in both systems is characterised by a double-layer repulsion with an electrosteric contribution dominating the shorter-range regime.
Journal ArticleDOI
A simple process for lignin nanoparticle preparation
Miikka Lievonen,Juan José Valle-Delgado,Maija-Liisa Mattinen,Eva Lena Hult,Kalle Lintinen,Mauri A. Kostiainen,Arja Paananen,Géza R. Szilvay,Harri Setälä,Monika Österberg +9 more
TL;DR: In this paper, a straightforward method to produce lignin nanoparticles from waste lignins obtained from kraft pulping is introduced, which is a natural biopolymer obtained mainly as a byproduct from pulp and paper-making industries, and is primarily burned to produce energy.
Journal ArticleDOI
Nanoscale cellulose films with different crystallinities and mesostructures--their surface properties and interaction with water.
Christian Aulin,Susanna Ahola,Peter Josefsson,Takashi Nishino,Yasuo Hirose,Monika Österberg,Lars Wågberg +6 more
TL;DR: Small incidence angle X-ray diffraction revealed that the nanocrystal and MFC films exhibited a cellulose I crystal structure and that the films prepared from N-methylmorpholine-N-oxide, LiCl/DMAc solutions, using the Langmuir-Schaefer technique, possessed a cellulOSE II structure.
Journal ArticleDOI
Effect of microfibrillated cellulose and fines on the drainage of kraft pulp suspension and paper strength
TL;DR: In this paper, different types of microfibrillated cellulose (MFC) and fines suspensions were produced, characterized, and then added to a paper-making pulp suspension, and the effects of salt concentration, pH, fixative type, dosage and type of fibrillar material on drainage were examined.
