Journal ArticleDOI

Lignin supracolloids synthesized from (W/O) microemulsions: use in the interfacial stabilization of Pickering systems and organic carriers for silver metal

Tiina Nypelö, +3 more
- 25 Feb 2015 - 
TL;DR: The use of related emulsions are introduced to enable in situ reduction of silver and loading of silver nanoparticles in lignin carriers and their properties were compared against those obtained by using traditional inorganic particles.
Journal ArticleDOI

Black liquor lignin biodegradation by trametes elegans

Mayra A. Lara, +7 more
- 01 Oct 2003 - 
TL;DR: The white rot fungus Trametes elegans was used for direct treatment of spent blackliquor from pulping processes with the aim to degrade solubilized lignin which is the primary organic by-product from the chemical digestion of lignocellulosic raw materials.
Journal ArticleDOI

Lignin changes after steam explosion and laccase-mediator treatment of eucalyptus wood chips.

Raquel Martín-Sampedro, +5 more
- 22 Jul 2011 - 
TL;DR: Thermogravimetic analyses of whole meal obtained from chips before and after steam explosion indicated an increase in lignin degradation temperature due to lignIn condensation, and application of LMS treatment caused a reduction in lIGNin and polysaccharide degradation temperatures.
Journal ArticleDOI

Antibacterial activity of silver nanoparticles synthesized In-situ by solution spraying onto cellulose.

Jinhua Yan, +3 more
- 20 Aug 2016 - 
TL;DR: The present research demonstrates facile and fast method for in-situ antibacterial AgNPs loading on cellulose substrates and indicates that the particle size was found to be 11 and 26nm for AgnPs nucleated on NFC and MFC-based papers respectively.
Journal ArticleDOI

High Internal Phase Oil-in-Water Pickering Emulsions Stabilized by Chitin Nanofibrils: 3D Structuring and Solid Foam .

Ya Zhu, +10 more
- 10 Feb 2020 - 
TL;DR: Chitin nanofibrils were produced under conditions that were less severe compared to those for other biomass-derived nanomaterials and used to formulate high internal phase Pickering emulsions (HIPPEs), and chitin-based HIPPEs were demonstrated as emulgel inks suitable for 3D printing via direct ink writing.
