This paper reported a strategy for selective lithium extraction from spent LiCoO2 (LCO) cathodes by two-step chlorination calcination combined with water-leaching. The feasibility of selective lithium extraction by two-step chlorination calcination was predicted by the thermodynamic analysis. The elements of Li and Co in the LiCoO2 cathode material were converted into water-soluble LiCl and CoCl2 respectively after pretreatment at 350 °C. Afterward, the generated CoCl2 reacted with the remaining LiCoO2 and converted into water-soluble LiCl and water-insoluble Co3O4 with temperatures increased. The results showed that 96.56% of the lithium can be recovered as LiCl and 95.23% Co in the form of Co3O4. © Published under licence by IOP Publishing Ltd.

Catalytic filters including catalytic bag filters and catalytic filter candles, which couple the filters with denitrification catalysts to obtain the ability to simultaneously remove SOx, NOx and dust, have become the promising applied technology for the integrated flue gas treatment because of their huge advantages in reducing the initial investment, floor occupancy and maintenance cost. In this review, we will summarize the recent advances in the development of catalytic filters in terms of their process principles, filter material, denitrification catalysts, structure-function relationships and industrial applications. Moreover, suggestions about the current challenges and future opportunities are also given from the viewpoints of catalysts and filter material design, catalytic filter preparation methods, and their poisoning and regeneration, etc. With the further development of theory and engineering research, the extensive industrial application of catalytic filters in the field of multiple pollutants flue gas treatment is highly anticipated in the future.

Acidic and basic sites of catalysts are essential tools in CO2 capture and activation. This work fabricated Zr, N-ZnO/ZnAl-LDH-IL composites in ionic liquid and methanol systems and were used to catalyze the synthesis of ethylene carbonate from ethylene glycol and CO2. The prepared composites have a high specific surface area of 205.542 m2 g-1. The Zr, N-ZnO/ZnAl-LDH-IL composite has a 4.16 times increase in the strong basic sites compared to N-ZnO/ZnAl-LDH-IL, mainly attributed to the fact that Zr-doped effectively induced changes in the reactive groups on the catalyst surface, increasing the percentage of pyridinic-N groups from 5.48% to 22.25%, inducing more C-atoms adjacent to pyridine-N to exhibit strongly basic sites favours the activation of CO2 and ethylene glycol. The experimental results show that the Zr, N-ZnO/ZnAl-LDH-IL composites have the best catalytic performance without adding any dehydrating agent at about 4.76 mmolEC gCat.-1 h-1. In addition to elucidating the possible catalytic pathways and reaction mechanisms of the composites for ethylene glycol and CO2 catalysis, we have also investigated the doping of La, Fe, Ce and Cu. Current work also indicates a new and promising strategy for synthesizing novel inorganic materials in ionic liquids and methanol. © 2023, The Authors. All rights reserved.

Electrocatalytic depolymerization of lignin into value-added chemicals offers a promising technique to make biorefining sustainable. Herein, we report a robust trimetallic PdNiBi electrocatalyst for reductive C-O bond cleavage of different lignin model dimers and oxidized lignin under mild conditions. The reduction reaction proceeds with complete substrate conversion and excellent yields toward monomers of phenols (80-99%) and acetophenones (75-96%) in the presence of an ionic liquid electrolyte with operational stability. Systematic experimental investigations together with DFT calculations reveal that the outstanding performance of the catalyst results from the synergistic effect of the metal elements, which facilitates the easier formation of a key Cα radical intermediate and the facile desorption of the as-formed products at the electrode. The results open up new opportunities for lignin valorization through the green electrocatalytic approach. © 2023, The Authors. All rights reserved.

Hyperhomocysteinemia (HHcy) is strongly associated with cardiovascular diseases (CVDs), and it has been identified as a risk factor for thrombotic diseases. Most patients with HHcy die from various complications closely related to thrombotic diseases. However, the underlying mechanisms have not been fully elucidated. G protein-coupled receptors (GPCRs), the central regulators of the cardiovascular system, primarily control platelet activation. By examining the effects of HHcy on a panel of GPCRs involved in platelet aggregation, we found that HHcy systematically modulated biased GPCR signaling through the inhibition of desensitization by β-arrestins and the amplification of G protein signals. We further revealed that the N-homocysteinylation of β-arrestin1/2 at lysine (K) residues (K294/K296) disrupted the interaction between β-arrestins and GPCRs. The aforementioned phenomenon may be universal because HHcy was found to modulate the signaling bias of 9 other randomly selected GPCRs. Moreover, we found that the proinflammatory effects of homocysteine and homocysteine thiolactone were weakened in Arrb2^–/– mice and that the reintroduction of wild-type but not K296R β-arrestin2 mutants (in mice) into primary peritoneal macrophages reversed these effects. Notably, in Arrb2^K296R mice, HHcy-induced thrombus formation and platelet aggregation were reversed. Our results suggest that a G-biased agonist could be a better choice for disease therapy under HHcy conditions. Collectively, our findings demonstrate that the N-homocysteinylation of β-arrestin1/β-arrestin2 actively modulates the biased property of GPCR signaling, which contributes to the pathophysiology of HHcy-related CVDs and provides insight into the selection of agonists for the treatment of diseases under HHcy conditions. © 2025 American Society of Hematology

Pleurotus ostreatus (P. ostreatus) is one of the most popular edible mushrooms worldwide and has been proposed as a candidate for human selenium (Se) supplementation. This study developed a Se-biofortification method, and evaluated the effect of 2,4-Dichlorophenoxyacetic acid (2,4-D), Na2SeO3 addition amounts and initial pH on P. ostreatus mycelium growth, nutritional value, and mineral accumulation. The optimal growth conditions were identified as 2,4-D 2.00 mg L-1, Na2SeO3 30.65 mg L-1, and initial pH 5.97 by Box-Behnken design. The optimization resulted in the biomass of 15.75 g L-1 and the organic Se content of 594.85 mg Kg-1, which was 2.50 and 8.03 times higher than the control group, respectively. In parallel, the contents of polysaccharides, proteins, essential amino acids, major functional components, and several minerals in mycelium were increased to varying degrees. Above results indicated that 2,4-D could be an effective stimulant for Se biofortification. © 2024, The Authors. All rights reserved.
