Ultrasound-laccase pre-treatment enhances agarwood essential oil extraction and bioactivity.

Agarwood essential oil is prized for its elegant aroma and pharmacological properties; however, the traditional hydrodistillation method suffers from inefficiencies, constraining the industrial potential of agarwood. We proposed an ultrasonic-assisted laccase synergistic pretreatment technique that enhanced extraction throughput by 70.90 % compared to the traditional method by facilitating pore formation in agarwood and expediting the release of essential oil.

Effect of delignification on shrinking and swelling of poplar wood assessed using digital image correlation technique.

This study investigates lignin's influence on the hygroscopic behavior of poplar wood. Delignification was achieved using an acidic NaClO solution, and digital image correlation (DIC) was employed to measure strain distribution during shrinking and swelling across relative humidity (RH) ranging of 0 % to 97 %. Results showed that lignin removal increased equilibrium moisture content (EMC) by up to 3.

Gravity-driven rattan-based catalytic filter for rapid and highly efficient organic pollutant removal.

Metal organic frameworks hold great promise as heterogeneous catalysts in sulfate radical (SO) based advanced oxidation. However, the aggregation of powdered MOF crystals and the complicated recovery procedure largely hinder their large-scale practical applications. It is important to develop eco-friendly and adaptable substrate-immobilized metal organic frameworks.

Structural organization of the cell wall polymers in compression wood as revealed by FTIR microspectroscopy.

Glucomannan was more strongly oriented, in line with the orientation of cellulose, than the xylan in both compression wood and normal wood of Chinese fir. Lignin in compression wood was somewhat more oriented in the direction of the cellulose microfibrils than in normal wood. The structural organization in compression wood (CW) is quite different from that in normal wood (NW).

Dual-emitting film with cellulose nanocrystal-assisted carbon dots grafted SrAlO, Eu, Dy phosphors for temperature sensing.

In this study, we synthesized a novel dual-emitting fluorescent phosphor from cellulose nanocrystal (CNC)-assisted carbon dots (CDs)-grafted SrAlO, Eu, Dy (SAO) through a facile core-shell process. The CNC-CDs-coated SAO presents excellent scattered dual-emission and improved water resistance without destruction of the SrAlO crystals. The phosphors were then reacted with coupling amino-silane and assembled with nanofibrillated cellulose skeletons to create flexible isotropic films.
