Quantification of Native Lignin Structural Features with Gel-Phase 2D-HSQC0 Reveals Lignin Structural Changes During Extraction

Our ability to study and valorize the lignin fraction of biomass is hampered by the fundamental and still unmet challenge of precisely quantifying native lignin's structural features. Here, we developed a rapid elevated-temperature H-1-C-13 Heteronuclear S ...

Selecting Suitable Near-Native Lignins for Research

Jeremy Luterbacher

There are several methods to isolate near-native lignins, including milled-wood lignin, enzymatic lignin, cellulolytic enzyme lignin, and enzymatic mild-acidolysis lignin. Which one is the most representative of the native lignin? Herein, near-native ligni ...

Catalyst support and solvent effects during lignin depolymerization and hydrodeoxygenation

Jeremy Luterbacher, Florent Emmanuel Héroguel

We studied and compared the hydrodeoxygenation (HDO) and depolymerization of aldehyde-stabilized lignin and 4-propylguaiacol (PG), a model lignin monomer. We demonstrated by liquid phase adsorption that PG HDO catalyzed by Ru/C can be achieved in isooctane ...

Highly Selective Oxidation and Depolymerization of α,γ-Diol Protected Lignin

Jeremy Luterbacher, Wu Lan, Jean Thierry C Behaghel de Bueren

Lignin oxidation offers a potential sustainable pathway to oxygenated aromatic molecules. However, current methods that use real lignin tend to have low selectivity and a yield that is limited by lignin degradation during its extraction. We developed stoic ...

An “ideal lignin” facilitates full biomass utilization

Jeremy Luterbacher, Li Shuai, Yuan Li

Lignin, a major component of lignocellulosic biomass, is crucial to plant growth and development but is a major impediment to efficient biomass utilization in various processes. Valorizing lignin is increasingly realized as being essential. However, rapid ...

Comportement en traction d'éléments en Béton de Fibres Ultra Performant combiné aces des barres d'armature

Eugen Brühwiler, Emmanuel Denarié, John Wuest, Julien Michels

L’objectif des interventions sur des ouvrages d’art est d’améliorer la durabilité et d’augmenter la résistance pour assurer la sécurité structurale. La combinaison de BFUP avec des armatures, peuvent répondre à ces exigences. Le comportement à la rupture d ...
