In this work, continuous carbon dioxide (CO2) absorption-desorption experiments under simulated flue gas conditions and techno-economic analysis of CO2 capture using a novel water-lean ionic liquid (IL) absorbent were comprehensively combined to evaluate the feasibility of industrial applications. Thermodynamic and kinetic properties of the absorbent such as heat capacity, thermal conductivity, and absorption rate were explored and a reliable thermodynamic model was conducted. Meanwhile, continuous absorption-desorption experiments were carried out using a laboratory-scale continuous flow system (LCFS) to optimize operational parameters and assess the absorbent stability. Under optimal conditions, the CO2 concentration in the purified gas can be reduced to 0.70%, and the capture efficiency was as high as 95.76%. After 650 hours of continuous experiments under simulated flue gas, the IL concentration in the absorbent remained essentially unchanged, showing excellent stability. Based on above experimental results, a process model was developed in ASPEN Plus and validated. The validated model was further scaled up to a commercial scale and a techno-economic analysis was performed to evaluate the energy consumption and cost. The regeneration energy consumption (Qreg) for the absorbent was 1.31 GJ tCO2-1, and the total cost of capture was 38.81 $ tCO2-1, indicating strong potential for industrial application. © 2025, The Authors.

Cooking oil fumes (COFs), which primarily consist of oil droplets and volatile organic compounds (VOCs) generated during Chinese cooking, are typically treated using liquid absorption methods due to their operational simplicity and relatively high purification efficiency. However, this method generates waste liquid, leading to secondary pollution Membrane separation is considered an effective approach to addressing secondary pollution issues at low cost and high efficiency. However, achieving simultaneous high flux and separation efficiency for both dispersed and emulsified oils in aqueous solutions remains challenging, particularly while maintaining operational stability. In this work, we firstly fabricated titanium dioxide coated on the stainless steel mesh (TiO2-SSM) through spin coating TiO2 sol following calcination, which has superhydrophilic and underwater superoleophobic properties, and can separate oil–water mixtures (dispersed oil) with high flux and efficiency (over 95%). Then, the TiO2-SSM was further handled by NaOH hydrothermal treatment to obtain TiO2 arrays structure on the surface (H-TiO2-SSM). It gains the ability to separate both dispersed and emulsified oil, with a separation efficiency of 70%, due to the demulsification by the TiO2 arrays. After stacking the two layers of H-TiO2-SSM, the separation efficiency can be increased to 95%. Furthermore, the membrane exhibited great chemical and mechanical stability, which may show application prospects in the field of oil–water separation. © 2025 Elsevier B.V.

The influences of FeOx on viscosities, structures and phase transformation of CaO-Al2O3-SiO2-MgO-BaO-(1-7 wt%)FeOx bosh slags were researched. The slag viscosity and the break point temperature gradually reduced with adding FeOx from 1 wt% to 7 wt%. Raman spectra and XPS results indicated that higher FeOx content in bosh slags could facilitate to form uncomplicated silicate units, which was conducive to decreasing the slag polymerization degree and the viscosity. From the XRD results of the slag at different temperatures, merwinite and melilite phase was precipitated and coexisted in bosh slags when the temperature was lower than the break point temperature, and the species of the crystalline solids was not changed with the addition of FeOx. Finally, the relationship among the viscosity, structure and crystal phase was further discussed. At high temperature, the bosh slag viscosity was mainly influenced by the microstructure. With the temperature decreasing and the formation of crystalline phases, the viscosity was simultaneously affected by the structure and solid phase. When the temperature was further reduced, a lot of crystals were crystallized from the molten slag and the viscosity was significantly determined by the size and morphology of the solid crystal. The comprehensive influences of the microstructure and macroscopic phase increased the viscosity with reducing the temperature. © 2025 Elsevier Ltd and Techna Group S.r.l.

Critical limb ischemia (CLI) faces high rates of amputation and mortality. Despite advancements in surgical and endovascular interventions, their invasiveness and restricted applicability leave many CLI patients classified as “no-option” cases. Therapeutic angiogenesis strategies offer prospects for revascularization, but their efficacy remains suboptimal. Herein, we developed a nanomedicine, mitochondria-targeted zinc-doped ascorbic acid-derived carbon dots (TPP-Zn@ACDs), which simultaneously restores mitochondrial function and amplifies regenerative signaling to synergistically boost angiogenesis in ischemic limbs. TPP-Zn@ACDs integrate potent antioxidative properties of carbon dots and the pro-regenerative effects of Zn²⁺, with triphenylphosphine (TPP) and polyethylene glycol (PEG) functionalization endowing precise mitochondrial targeting and enhanced biocompatibility, thereby localizing therapeutic effects to the core of oxidative stress mitigation and regenerative signaling transduction. In vitro, TPP-Zn@ACDs improved mitochondrial function by reducing reactive oxygen species, restoring mitochondrial membrane potential and enhancing ATP production, through activation of the SIRT1/PGC-1α signaling pathway. Further, the proliferation, migration, and tube formation activities of endothelial cells were increased, while hypoxia-induced apoptosis and necrosis was inhibited effectively. Notably, leveraging mitochondrial restoration in endothelial cells, TPP-Zn@ACDs subsequently reprogrammed macrophages from an M1 pro-inflammatory phenotype to an M2 anti-inflammatory phenotype. In vivo, TPP-Zn@ACDs demonstrated remarkable therapeutic efficacy in a mouse CLI model, achieving robust blood flow recovery, increased microvascular density, and improved immune microenvironment. Together, this study proposes TPP-Zn@ACDs as a versatile engineering nanomedicine for mitochondria-targeted therapy, providing a scalable approach to breakthrough angiogenic efficacy in isc

Poly(lactic acid) (PLA) possesses excellent biocompatibility and biodegradability for the construction of biomaterials. However, its limited crystallinity largely restricts practical application. In this study, four poly(l-lactic acid) (PLLA) copolymers were synthesized by incorporating two different molecular weights of PEG/mPEG (1K and 2K) chains with l-lactide via ring-opening polymerization (ROP). The impact of PEG/mPEG chains on the hydrophilicity and mechanical properties of the resulting copolymers, their crystallization kinetics, and activation energy was also examined. The results demonstrate that introducing PEG/mPEG chains could significantly improve the hydrophilicity, crystallinity, and crystallization rate and reduce the maximum crystallization temperature of the copolymer materials. Among the PLLA copolymers, PLLA-mPEG (2K) exhibits the most remarkable improvements in polymer crystallinity, crystallization rate, and reduction of the maximum crystallization temperature. The advancements in copolymer material properties were anticipated to significantly expand the potential applications for PLLA-based polymer materials, which also greatly improved the applicability as sustainable and controllable biopolymer materials. © 2025 American Chemical Society.

The global demand for lithium resources is rapidly increasing, primarily driven by the growing use of lithium-based batteries in electric vehicles and stationary energy storage systems. Salt lakes represent a cornerstone of the global lithium supply, but efficient separation of Mg2+ and Li+ remains a significant challenge in lithium extraction. This review examines the key techniques for lithium extraction from salt lakes, focusing on their respective advantages and limitations. Nanofiltration (NF) membranes, known for their selective separation properties, show considerable potential for the efficient separation of Mg2+ and Li+. The paper discusses the fundamental separation mechanisms and mass transfer models associated with NF membranes, emphasizing recent developments in Mg2+/Li+ separation through four main approaches: enhancing the Donnan effect, optimizing membrane pore size, integrating dual-mechanism synergistic designs, and optimizing membrane support layers. Additionally, the review proposes three future research directions specifically aimed at advancing NF membrane design for Mg2+/Li+ separation. This review offers a timely and relevant analysis of the strategies used to enhance NF membrane performance in this important application. © 2025

Catalytic hydrogenation of carbon dioxide (CO2) to methanol is a key strategy for mitigating climate change and promoting a sustainable methanol economy. In recent years, copper-based catalysts have attracted much attention due to their abundant reserves, low cost and excellent catalytic performance. This paper systematically reviews the latest progress of copper-based catalysts and deeply explores the process principles of carbon dioxide hydrogenation to methanol, covering multiple pathways such as direct hydrogenation, reforming, water-gas shift and carbon monoxide hydrogenation, and carboxylic acid intermediates. At the same time, the historical evolution of methanol synthesis catalysts and various preparation methods of copper-based catalysts are analyzed, their advantages and disadvantages and adjustment strategies are discussed, and methods for improving catalytic performance by introducing different supports and additives are introduced. In addition, the reaction mechanism of carbon dioxide-based methanol synthesis is explained, and the current status and challenges of industrial development are outlined, especially key issues such as demonstration projects, commercial operations, and carbon dioxide capture, green hydrogen source costs, and catalyst deactivation. Based on this, this paper proposes a series of suggestions for future research directions, aiming to improve catalyst performance, optimize operating conditions, and accelerate its commercialization process, so as to contribute to the realization of carbon neutrality goals. © 2025 Elsevier B.V.

The environmental impact of biodegradable microplastics (BMPs) is profoundly influenced by aging-induced surface transformations, yet their interactions with persistent organic pollutants, such as perfluorooctanoic acid (PFOA), remain poorly understood. This work investigates how aging polylactic acid (PLA), a common BMP, in simulated surface water for 80 days alters its physicochemical properties and behavior towards PFOA. Aging triggered oxidative and hydrolytic degradation, leading to pronounced morphological changes, including increased surface roughness, hydrophilicity, and oxygen-to-carbon (O/C) ratio from 0.82 to 1.28. These transformations introduced hydroxyl and carboxyl functional groups, shifting the PFOA adsorption mechanism from physisorption (in fresh PLA) to chemisorption (in aged PLA) via stronger electrostatic interactions and hydrogen bonding. Additionally, kinetic and isotherm analyses revealed a tenfold increase in PFOA monolayer adsorption capacity for aged PLA (PLA-80) compared to pristine PLA. Density functional theory (DFT) calculations corroborated these findings, demonstrating a reduced HOMO–LUMO energy gap upon PFOA adsorption, indicative of enhanced electronic reactivity and charge transfer. Topological analysis further identified multiple hydrogen-bonding sites, confirming the dominance of electrostatic forces in pollutant retention. These results underscore the critical role of aging in amplifying BMPs’ environmental reactivity, emphasizing the urgent need to incorporate aging processes into risk assessments for biodegradable plastics. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.

The sluggish metabolism of 3,5,6-trichloro-2-pyridinol (TCP) in anoxic or anaerobic environments represents a significant challenge in bioremediation of TCP-contaminated habitats. Although the promotion of anaerobic biodegradation by insoluble iron minerals has been recognized, the impact and mechanisms of soluble iron ions remain poorly understood. Herein, the soluble Fe(II) was firstly incorporated into the anaerobic biodegradation of TCP by Pseudomonas aeruginosa D-2 and its response of TCP metabolism to the introduction of Fe(II) were investigated. The Fe(II) ion significantly enhanced the anaerobic biodegradation of TCP (50 mg/L) with the removal efficiency increasing from 50.24% to 80.32% within 72 h, along with noticeable cellular proliferation. Interestingly, this process was accompanied by a dynamic equilibrium transformation between Fe(II) and Fe(III). Further study revealed TCP's dechlorination metabolite was substantially degraded by strain D-2 coexisting with Fe(III), concurrently with the reduction of Fe(III) to Fe(II). These findings suggested the iron ions redox cycle significantly promoted the anaerobic biodegradation of TCP. Moreover, metabolomics analysis conformed strain D-2 could perform anaerobic reductive dechlorination of TCP. More importantly, genomic and transcriptomic analyses first revealed Fe(II) markedly enriched energy metabolism pathways, such as TCA cycle and oxidative phosphorylation, and obviously up-regulated some iron-dependent enzymes crucial for ring-cleaving and energy metabolism. These up-regulation may provide ample energy (ATP) and reducing power for the cell growth and the initiation of reductive dechlorination of TCP. This study revealed the effects and mechanism for promoting TCP anaerobic respiration activity by the iron ions redox cycle, acting as an 'energy buffer, in bioremediation of halogenated aromatic contaminants. © 2025, The Authors.
