Highly dispersed Ru nanoparticles anchored on NiAl layered double oxides catalyst for selective hydrodeoxygenation of vanillin [PDF]

The hydrodeoxygenation (HDO) of lignin-derived feedstocks into value-added chemicals with high efficiency and selectivity is desirable for the utilization of biomass resource. The complex oxygen-containing groups of lignin-derived substance result in the challenge of the low selectivity toward the required product.

How Soil Organic Matter Composition Controls Hexachlorobenzene-Soil-Interactions: Adsorption Isotherms and Quantum Chemical Modelling [PDF]

Science of the Total Environment 476-477, 98 (2014), 2013
Hazardous persistent organic pollutants (POPs) interact in soil with the soil organic matter (SOM) but this interaction is insufficiently understood at the molecular level. We investigated the adsorption of hexachlorobenzene (HCB) on soil samples with systematically modified SOM.

CO2‐Responsive Smart Wood Scaffold for Natural Organic Matter Removal without Secondary Pollution

Advanced Materials, EarlyView.
A CO2‐responsive smart wood scaffold is developed for sustainable water purification, achieving efficient natural organic matter (NOM) removal and microbial disinfection without secondary pollution. The CO2‐responsive polymer coating undergoes protonation upon CO2 exposure, enabling strong cation−π interactions with NOM.

Vessel-specific reintroduction of CINNAMOYL-COA REDUCTASE1 (CCR1) in dwarfed ccr1 mutants restores vessel and xylary fiber integrity and increases biomass [PDF]

, 2018
Lignocellulosic biomass is recalcitrant toward deconstruction into simple sugars due to the presence of lignin. To render lignocellulosic biomass a suitable feedstock for the bio-based economy, plants can be engineered to have decreased amounts of lignin.

Banana skin: a novel material for a low-cost production of laccase [PDF]

arXiv, 2008
Laccases (benzenodiol: oxygen oxidoreductases; EC 1.10.3.2) are multicopper oxidases of wide substrate specificity mainly found in white-rot fungi, which are the only microorganisms able to degrade the whole wood components, but they are also expressed in bacteria and higher plants. Laccases are used currently in biotechnological processes because this
