Electrospinning of Softwood Kraft Lignin With Cellulose Acetate: Dye Adsorption, Carbonization, and Carbon Dioxide Capture

open access: yesChemSusChem, Volume 19, Issue 10, 27 May 2026.
Electrospun nanofibers from unfractionated softwood kraft lignin and cellulose acetate enable up to 80% lignin incorporation without modification. The materials support sequential use, first for dye removal from water and subsequently for carbon dioxide capture after carbonization.

Full Sequence Bleaching with Dimethyldioxirane [PDF]

open access: yes, 1995
Research work to date has shown dimethyldioxirane to be a very powerful, yet highly selective oxidant. Dimethyldioxirane bleaching may become more important in the future with legislative restrictions on chlorine based bleaching agents as it contains no ...

Influence of Botanical Origin on the Optical, Surface, and Nanomechanical Properties of Nanocellulose‐Based Films: A Comparative Study

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 19, May 15, 2026.
Schematic representation of the processing and multiscale characterization of nanocellulose films from different botanical sources. ABSTRACT Although the influence of botanical origin on nanocellulose properties is well recognized, an integrated multiscale framework linking chemical composition, fractal surface descriptors, and nanomechanical behavior ...

Effect of Charcoal and Kraft-Lignin Addition on Coke Compression Strength and Reactivity

open access: yesEnergies, 2017
The aim of this research was to investigate the effects of charcoal and Kraft-lignin additions on the structure, cold compression strength, and reactivity of bio-cokes produced at the laboratory scale. Bio-cokes were prepared by adding charcoal and Kraft-

Non-Einstein Viscosity Phenomenon of Acrylonitrile–Butadiene–Styrene Composites Containing Lignin–Polycaprolactone Particulates Highly Dispersed by High-Shear Stress

open access: yes, 2019
Lignin powder was modified via ring-opening polymerization of caprolactone to form a lignin–polycaprolactone (LPCL) particulate. The LPCL particulates were mixed with an acrylonitrile–butadiene–styrene (ABS) matrix at an extremely high rotational speed ...

Identification of manganese superoxide dismutase from Sphingobacterium sp. T2 as a novel bacterial enzyme for lignin oxidation [PDF]

open access: yes, 2015
The valorisation of aromatic heteropolymer lignin is an important unsolved problem in the development of a biomass-based biorefinery, for which novel high-activity biocatalysts are needed.

Nanolignin Functional Separators for Flexible Lithium–Sulfur Batteries With Enhanced Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
Nanolignin‐functionalized separators, incorporating lignin nanoparticles into a crosslinked PEGDA coating applied on commercial separators, reduce polysulfide shuttling, thereby enhancing cycling performance in flexible lithium–sulfur pouch cells, while also improving thermo‐oxidative stability and flame retardancy.

Comparative Evaluation of Additives in Softwood Fractionation: Impacts on Lignin Recovery and Pulp Quality

open access: yesChemSusChem, Volume 19, Issue 8, 28 April 2026.
Chemical lignin stabilization during acid hydrotropic fractionation is shown to distinctly influence delignification, lignin quality, and pulp performance. Phenol enhances lignin removal, while thiol‐based modifier yields light‐colored lignin, high recovery, and strong pulp.
