Improved Lignin Polyurethane Properties with Lewis Acid Treatment [PDF]
, 2012 Chemical modification strategies to improve the mechanical properties of lignin-based polyurethanes are presented. We hypothesized that treatment of lignin with Lewis acids would increase the concentration of hydroxyl groups available to react with ...

An environmentally benign antimicrobial nanoparticle based on a silver-infused lignin core [PDF]
, 2015 Silver nanoparticles have antibacterial properties, but their use has been a cause for concern because they persist in the environment. Here, we show that lignin nanoparticles infused with silver ions and coated with a cationic polyelectrolyte layer form

Response to dietary tannin challenges in view of the browser/grazer dichotomy in an Ethiopian setting : Bonga sheep versus Kaffa goats [PDF]
, 2015 It has been suggested that goats (typical browser) are better adapted to digest tannin-rich diets than sheep (typical grazer). To evaluate this, Bonga sheep and Kaffa goats were used in a 2x3 randomized crossover design with two species, three diets, and

Lignin Valorization via Acidolysis with Ethylene Glycol Stabilization [PDF]
, 2021 This thesis describes several aspects of lignin acidolysis with ethylene glycol stabilization and possible applications of the obtained monomers. An efficient strategy was developed to convert native lignin in lignocellulose to new lignin-derived platform chemicals (G/S-C2-acetals), a set of monomers that is not accessible via other lignin ...

A statistical theory of polymer network degradation [PDF]
, 2014 A statistical theory was proposed for the degradation (random scission of chains) of a network having f-functional nodes in the case where all chains contain equireactive groups and a chain scission event does not create new groups or suppress more than ...

Lignin-Graft-Poly(lactic-co-glycolic) Acid Biopolymers for Polymeric Nanoparticle Synthesis [PDF]
ACS Omega, 2020 A lignin-graft-poly(lactic-co-glycolic) acid (PLGA) biopolymer was synthesized with two types of lignin (LGN), alkaline lignin (ALGN) and sodium lignosulfonate (SLGN), at different (A/S)LGN/PLGA ratios (1:2, 1:4, and 1:6 w/w). 1H NMR and Fourier-transform infrared spectroscopy (FT-IR) confirmed the conjugation of PLGA to LGN.
