Abstract Background In recent years, lytic polysaccharide monooxygenases (LPMOs) that oxidatively cleave cellulose have gained increasing attention in cellulose fiber modification. LPMOs are relatively small copper-dependent redox enzymes that occur

Cellulose (rayon) filaments were exposed to various concentrations of hydrochloric acid under aqueous and non-aqueous conditions in order to study differences in degradation. Two sources of polymeric diphenylmethane diisocyanate (pMDI) were used as n

An alternative ammonoxidation protocol was developed. With this new approach in “solid-state” mode, one single solid reagent is sufficient to equip lignin with different N-functionalities.

The development of sustainable plastics from abundant renewable feedstocks has been limited by the complexity and efficiency of their production, as well as their lack of competitive material properties. Here we demonstrate the direct transformation

The three cellulosic key chromophores, 2,5-dihydroxy-[1,4]-benzoquinone, 5,8-dihydroxy-[1,4]-naphthoquinone and 2,5-dihydroxy-acetophenone, are nearly ubiquitous in cellulosic materials because of their special structures and resonance stabilization

The electron beam irradiation (EBI) of native lignin has received little attention. Thus, its potential use in lignin-based biorefineries is not fully understood. EBI was applied to selected lignin samples and the structural and chemical changes were

Sugar-based biorefineries have faced significant economic challenges. Biorefinery lignins are often classified as low-value products (fuel or low-cost chemical feedstock) mainly due to low lignin purities in the crude material. However, recent resear

Lignosulfonates are bulk‐scale byproducts of industrial sulfite pulping. Their amphiphilic character plays a central role in their successful application in large‐scale materials production. As an inherent feature of the chemical structure, this

In technical lignins, functionality is strongly related to molar mass. Hence, any technical lignin exhibits concurrent functionality-type distribution (FTD) along its molar mass distribution (MMD). This study combined preparative size-exclusion chrom
