Summary: The purpose of this study is to develop an eco-friendly adsorbent based on ionic liquid (IL) to selectively recover Au (I) from bioleachate and to understand its adsorption mechanism. IL-modified chitosan fibers (ILCFs) were prepared as a fast and highly efficient adsorbent for Au(I) recovery under alkaline conditions. The ILCFs exhibited a uniform cross-sectional diameter of 31.2 +/- 1.1 μm. Characterization using SEM, FT-IR, and XPS revealed the adsorption mechanism of Au(I) on ILCFs. The maximum Au(I) adsorption capacity of the ILCFs was found to be 357.0 +/- 13.2 mg/g based on the Langmuir model. An adsorption equilibrium was reached within 7 minutes, with rate constants of pseudo-1st-order and pseudo-2nd-order being 0.8912 +/- 0.0569 1/min and 0.0049 +/- 0.0002 g/mg min, respectively. Furthermore, the ILCFs exhibited high selectivity for Au(I) in waste printed circuit board bioleachate. The developed ILCFs are effective in selectively adsorbing Au(I) and have potential in recovering it from urban mining bioleachates.

Summary: This study developed an integrated fractionation strategy for producing nanocrystalline cellulose (NCC) from wood, which can solve the problems of low yield and environmental impact in the traditional process. The strategy could tolerate a high CRM lignin content, provide a high NCC yield, and result in crystal transition of NCC from cellulose I to cellulose II. The presented study proposed a partial/selective dissolution mechanism for NCC production. It provides a promising method for high-value utilization of lignocellulosic biomass.

Summary: In this study, switchable ionic liquids were synthesized and screened to improve the polarity and recyclability of deep eutectic solvents. By coupling with hydrogen-bond donors, a switchable-DES system with modified properties, such as viscosity, conductivity, and pH, was formed, leading to enhanced solubility of lignin compounds and improved molecular weight and uniformity. This proposed system has potential applications in the fractionation of lignin compounds and downstream industrial processes.

Summary: The separation and recovery of Li+ from high-ratio Mg/Li salt lake brines using the ionic liquid [C(2)mim][NTf2] with tributyl phosphate (TBP) and sulfonated kerosene system as an extractant in a homemade membrane emulsification circulation (MEC) extractor was investigated. The extraction efficiency of Li+ was found to be up to 96.0% within 8 minutes in single-element extraction experiments. The MEC extractor exhibited better extraction performance compared to oscillating and stirring extraction methods in multi-element experiments. The extraction system had extensive applications due to its insensitivity to pH and temperature and the ability to extract Li+ without the addition of co-extraction agents.

Summary: The study reveals that the reconstitution of chitosan structure during regeneration from 1-ethyl-3-methylimidazolium acetate depends largely on the choice of anti-solvent (water, methanol or ethanol). Water as an anti-solvent promotes chitosan chain rearrangement and crystallite formation. Density functional theory simulation shows that the number of hydrogen bonds formed between anti-solvents and [Emim][OAc] is in the order of water > methanol > ethanol.

Summary: Biomass pretreatment is an essential step in the production of second-generation biofuels from lignocellulosic biomass. Recent research has focused on the efficiency of conventional biomass pretreatment solvents in carbohydrate conversion, rather than considering their potential hazards and carbon intensity. This review discusses the use of environmentally friendly and sustainable alternatives, such as biomass-derived solvents, including carbohydrate and lignin-derived solvents. It also examines different types of pretreatment solvents, such as organic, ionic liquid, and deep eutectic solvents, and the role of water as a co-solvent. The review concludes with a discussion on the challenges and prospects of utilizing biomass-derived pretreatment solvents for sustainable and green biorefinery.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
