Beer quality generally diminishes over time as staling compounds accumulate through various oxidation reactions. Here, we show that refermentation, a traditional practice where Saccharomyces cerevisiae cells are added to beer prior to bottling, diminishes the accumulation of staling aldehydes. However, commonly used beer yeasts only show a limited ...

The adsorption and self-assembly of several thiacarbocyanine dyes on hexagonal boron nitride (hBN) was investigated by combining steady-state spectroscopy and atomic force microscopy. The adsorption isotherms indicate that at saturation the density of the cationic TDC (5,5-dichloro-3-3′-diethyl-9-ethyl-thiacarbocyanine) molecules on hBN is similar ...
Chemical looping steam methane reforming (CL-SMR) provides an attractive route for hydrogen and syngas co-production through two successive steps of methane oxidation and steam splitting. However, there is also carbon formation through CH4 cracking which hampers the production of syngas (H-2 and CO) and the following pro-duction of pure H-2. This w...
Surface modification of cellulose nanocrystals (CNC) by organocatalysed grafting from ring-opening polymerization (ROP) of trimethylene carbonate was investigated. Organocatalysts including an amidine (DBU), a guanidine (TBD), an amino-pyridine (DMAP) and a phosphazene (BEMP) were successfully assessed for this purpose, with performances in the ord...

In the present work, three specific low weight average molecular weight (Mw) demethoxylated citrus pectin derived compounds (oligosaccharides) (CP₂₅ ₖDₐ, CP₃ ₖDₐ and CP₃.₈ ₖDₐ) were generated by means of enzymatic degradation and subsequent chemical demethylesterification of three starting pectin materials (CP74₁₄₄ ₖDₐ, CP53₁₅₁ ₖDₐ and CP38₁₁₆ ₖDₐ,...

Depolymerization of cellulose is often used as a (pre)treatment protocol within the catalytic valorization strategies of cellulose. Typical depolymerization protocols yield polymerization degrees above 70 anhydroglucose units (AGU). However, shorter cellulose fibers are of interest in the search for accessible dietary fiber additives or renewable m...
Chemical looping oxidative coupling of methane (CLOCM) is a novel process for the selective oxidization of methane to produce C-2(+) hydrocarbons. However, the high activity of oxygen carriers usually promotes the undesired complete or partial oxidation of methane to form large amounts of COx. Herein, a series of novel composite oxide carriers of M...
