Selecting Suitable Near-Native Lignins for Research

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 ...

Extraction and controlled functionalization of lignin for materials applications

Stefania Bertella

Lignin is a renewable aromatic polymer that due to its abundance and unique chemical structure is a promising candidate to replace aromatic materials that are currently sourced from fossil oil. The same structure of lignin poses however drawbacks for its v ...

Lignin Functionalization for the Production of Novel Materials

Jeremy Luterbacher, Stefania Bertella

Lignin, a major constituent of lignocellulosic biomass, is the largest natural source of aromatic molecules and thus is an attractive feedstock for renewable chemical production. Direct incorporation of isolated lignin into materials has long been research ...

Establishing Lignin Structure-Upgradeability Relationships Using Quantitative 1H-13C Heteronuclear Single Quantum Coherence Nuclear Magnetic Resonance (HSQC-NMR) Spectroscopy

Jeremy Luterbacher, Masoud Talebi Amiri, Ydna Marie Questell-Santiago, Stefania Bertella

Lignin depolymerization could provide an attractive renewable aromatic feedstock for the chemical industry. Past studies have suggested that lignin structural features such as ether content are correlated to lignin’s upgradeability. An obstacle to the deve ...

Corncob Biorefinery for Platform Chemicals and Lignin Coproduction: Metal Chlorides as Catalysts

Wu Lan

A facile approach to a corncob biorefinery, focusing on both carbohydrate valorization and lignin stabilization, was proposed to coproduce platform chemicals (glucose, xylose, arabinose, and furfural) and lignin. Different metal chloride prehydrolyses of c ...

Formaldehyde stabilization facilitates lignin monomer production during biomass depolymerization

Yiming Li, Jeremy Luterbacher, Masoud Talebi Amiri, Florent Emmanuel Héroguel, Ydna Marie Questell-Santiago, Li Shuai

Practical, high-yield lignin depolymerization methods could greatly increase biorefinery productivity and profitability. However, development of these methods is limited by the presence of interunit carbon-carbon bonds within native lignin, and further by ...

Sensing hydrogen peroxide by carbon nanotube/horseradish peroxidase bio-nanocomposite

László Forró, Arnaud Magrez, Endre Horvath, Klara Hernadi

H2O2 is a product of reactions catalysed by several oxidase enzymes and it is essential in environmental and pharmaceutical analyses. The most commonly used enzyme in understanding the biological behaviour of catalysed oxidation of H2O2 is horseradish pero ...

Photocatalytic Nanolithography of Self-Assembled Monolayers and Proteins

Esther Amstad

Self-assembled monolayers of alkylthiolates on gold and alkylsilanes on silicon dioxide have been patterned photocatalytically on sub-100 nm length-scales using both apertured near-field and apertureless methods. Apertured lithography was carried out by me ...

Physico-chemical properties and photo-reactivity relationship for para-substituted phenols in photo-assisted Fenton system

César Pulgarin, Félicien Mazille

The reactivity of phenolic compounds can be drastically affected by the electronic nature of the substituting groups. In this work, the effect of physico-chemical properties on the reactivity via photo-assisted Fenton catalysis is reported for several para ...

Structural properties and photoreactivity relationships of substituted phenols in TiO2 suspensions

César Pulgarin, Sandra Parra Cardona

The reactivity of phenolic compounds can be drastically affected by the electronic nature of substituents and by their positions in the aromatic ring. In this work, structure effect on the photoreactivity via TiO2 catalysis is studied using several substit ...
