The Formation of Covalent Linkages in Lignocellulosic Biomass via the Oxocarbenium Intermediate

ChemPhysChem, EarlyView.
Density functional theory models show that the hydrated and acidic hemicellulose matrix in lignocellulosic biomass can generate oxocarbenium ions. These reactive intermediates can participate in the stable formation of glycosidic lignin‐carbohydrate covalent linkages, promoting recalcitrance in plant biomass.

Isoconiferoside, a New Phenolic Glucoside from Seeds of Panax ginseng

Molecules, 2011
A new phenolic glucoside, isoconiferoside (1), was isolated from the seeds of Panax ginseng (Araliaceae). The structure was determined to be 9-O-[b-D-glucopyranosyl-(1®6)-b-D-glucopyranosyl]-trans-coniferyl alcohol based on spectroscopic analyses (1H ...

In situ polymerisation of isoeugenol as a green consolidation method for waterlogged archaeological wood [PDF]

, 2017
Waterlogged archaeological wood is often in need of consolidation prior to drying to prevent shrinkage and cracking of the object. There is a need for new greener materials (than for example polyethylene glycol) and methods for consolidation to be ...

Effects of Pyrolysis Control Parameters on the Structural Properties of Biomass‐Derived Activated Carbon Materials and Their Energy Applications

The Chemical Record, EarlyView.
Tubular pyrolysis synthesis is a widespread method to produce activated carbons (ACs). This review focuses on the different controlling parameters of the tubular pyrolysis synthesis method and their influence on the performance of synthesized ACs, thereby considering both experimental aspects and the use of plant‐based biomasses (PBBs) as feedstock ...

Co‐Reactivity of Fragrances and Fragrance‐Markers in Patients With Positive Patch Tests to Chinese and Brazilian Propolis

Contact Dermatitis, EarlyView.
In this study, the patterns of co‐reactivity to the four fragrance markers present in the European baseline series (Myroxylon pereirae resin [balsam of Peru], colophonium, fragrance mixes 1 and 2) and to the fragrances limonene and linalool hydroperoxides in patients allergic to Brazilian propolis were investigated.

Photoluminescence Properties of Lignin With a Genetically Introduced Luminophore in a Transgenic Hybrid Aspen That Overproduces Feruloyl‐CoA 6′‐Hydroxylase

Plant Biotechnology Journal, EarlyView.
ABSTRACT Lignin, a major cell‐wall component of woody biomass, exhibits photoluminescent (PL) properties. Controlling the intensity and colour of the PL is essential for producing lignin‐based value‐added materials. Herein, we modify the PL properties of lignin via genetic engineering of novel luminophore structures. Feruloyl‐CoA 6′‐hydroxylase (F6′H1)
