Journal ArticleDOI

Charge and the dry-strength performance of polyampholytes. Part 2. Colloidal effects

Martin A. Hubbe, +6 more
- 05 Jul 2007 - 
TL;DR: In this paper, a series of polyampholytes having a constant ratio of cationic to anionic monomeric groups and molecular mass was used to investigate the effect of pH and ionizable groups on the strength of aqueous polymer mixtures.
Journal ArticleDOI

Carboxymethylated lignins with low surface tension toward low viscosity and highly stable emulsions of crude bitumen and refined oils

Shuai Li, +5 more
TL;DR: The ability of CML to stabilize emulsions and to contribute in their combustion was tested with light fuels after formulation of high internal phase systems (70% oil) that enabled operation of a fuel engine and highlighted the possibilities in high volume application for lignin biomacromolecules.
Journal ArticleDOI

Micro-patterns on nanocellulose films and paper by photo-induced thiol–yne click coupling: a facile method toward wetting with spatial resolution

Jiaqi Guo, +7 more
- 01 Jan 2018 - 
TL;DR: In this paper, photo-induced thiol-yne click coupling was applied to nanocellulose films and paper to develop micro-patterned surfaces via UV lithography, endowing the substrates with thin hydrophilic channels and hydrophobic boundaries between neighboring water droplets, as small as 100mm in width.
Journal ArticleDOI

Reinforcement of polypropylene with lignocellulose nanofibrils and compatibilization with biobased polymers

Ana Ferrer, +3 more
- 10 Sep 2016 - 
TL;DR: In this article, freeze-dried and milled lignocellulose nanofibrils (LCNF) were used to reinforce polypropylene (PP) nanocomposites.
Journal ArticleDOI

Production of bacterial nanocellulose (BNC) and its application as a solid support in transition metal catalysed cross-coupling reactions.

Sanja Jeremic, +10 more
- 15 May 2019 - 
TL;DR: Findings reveal that BNC is a good support material, and it can be used as a support for different catalytic systems, in metal-catalysed reactions and its recovery has been described.
