Objective: Pore is one of the important characteristics of wood identification. Aiming at the problems of poor robustness of pore segmentation due to random distribution and different sizes of pores and the impact of noise such as wood fiber, wood ray and axial parenchyma on the segmentation effect ...

The major compounds of cellulose and lignin in biomass could have varied contributions on distribution and properties of pyrolysis products by generating the volatiles of different structures via pyrolysis. In this paper, the co-pyrolysis of cellulose or lignin with sawdust were investigated,...

Antibiotics residues in aqueous environment and sewage sludge accumulation have become serious environmental issues. The aim of this study is to investigate the potential of ciprofloxacin (CIP) removal by sludge-based biochar prepared from co-pyrolysis of sewage sludge and bamboo waste (BW). The...

Bio-hydrogen production from lignocellulosic biomass has shown significant potential for helping to meet future energy demand. In the present work, we have utilized the Paulownia lignocellulosic biomass as feedstock for hydrogen production which has great potential for sustainable supply over the...

Vanillin is a natural flavoring agent that is widely used in the bioengineering industry. To enable sustainable development, joint consideration of bacterial performance and negative environmental impacts are critical to vanillin biosynthesis. In this study, a cold shock protein (csp) gene was...

Blue luminescent carbon quantum dots(B-CQDs) were synthesized by a simple one-step hydrothermal method using lignin and m-phenylenediamine as precursors. Green luminescent carbon quantum dots(G-CQDs) were synthesized by nitric acid oxidation. The optical properties and structures characteristics of ...

Novel and green cholinium amino acids-based deep eutectic solvents (DESs) and their aqueous mixtures were synthesized and employed in deconstructing poplar for hemicellulose fractionation. The effects of water content in DESs on hemicellulose dissociation and structural features were...

It is of great challenge to prepare lignin-derived carbon microfibers with suitable graphite crystallites due to the volatilization of incorporated polymers. In this work, we proposed a simple method for the construction of graphite crystallites based on the regulation of the hydrogen-bonding...

Cationic modification of cellulose fibers is an effective strategy to improve the absorptive capacity of anionic dyes and promote wastewater treatment. In this study, cationic cellulose nanofibers (CCNFs) with different degrees of substitution (DS) were prepared by grafting cellulose fibers with 2, ...

Grafting has been found to effectively reduce the prickly nature of Zanthoxylum armatum seedlings, but the molecular mechanisms are unclear. A comparative transcriptome analysis was performed on stems (JJ) and leaves (JY) of grafted stems (SJ) and leaves (SY) of non-grafted Zanthoxylum armatum...
