This study presents a high-value green recycling strategy for waste polyetheretherketone (PEEK) to fabricate a bioinspired “vine-wrapping” nanocomposite insulating paper from recycled PEEK fibers and self-prepared polyarylate (PAR) nanofibers. The multiscale synergy of the nanocomposite significantly enhances its dielectric performance. Micron-scale PEEK fibers form a three-dimensional scaffold, which provides mechanical support and carrier transport pathways. High-aspect-ratio PAR nanofibers exploit secondary thermoplasticity to infiltrate scaffold voids, refine pore structures, suppress electric field distortion, and inhibit electrical tree initiation. At the molecular level, strong dipole-dipole interactions between PEEK carbonyls and PAR esters, along with π-π stacking of aromatic rings, create a stable, hierarchical noncovalent interface. Consequently, the PEEK/PAR nanocomposite paper achieves a breakdown strength of 89.67 kV/mm, representing a 256.11% improvement over commercial aramid paper. After thermal aging (200 °C, 24 h), UV exposure (365 nm, 24 h), 100 folding cycles, and 20 kneading-folding cycles, the breakdown strengths remain at 34.14, 37.34, 17.51, and 17.06 kV/mm, respectively. These values are 2.3, 1.91, 1.38, and 2.31 times the strength of commercial aramid paper. These results indicate a viable pathway for developing sustainable, high-performance, paper-based insulation.

The recovery of valuable metals from spent lithium-ion battery (LIB) cathode powders via mechanical ball milling has gained widespread attention. However, the presence of leaching agents in one-step recycling significantly hinders the efficient leaching and large-scale processing of valuable metal ions from these cathode powders. Herein, we develop a scalable and environmentally friendly recycling process through stepwise dry-ball milling (D-BM) activation and wet-ball milling (W-BM) leaching to selective extract lithium (Li) from spent Li(Ni 0.5 Co 0.2 Mn 0.3 )O 2 cathode powders (SNCM) using oxalic acid (OA) and ascorbic acid (AC) as the agents. The result show that, even under a high solid-liquid (S/L) ratio condition (50 g L −1 ), the Li leaching efficiency reached near-complete extraction (96.92 %) and a high selectivity of 95.72 % within just 10 min. These can be attributed to the D-BM activated the SNCM via disrupting of lattice of the structure and introducing oxygen defects, while the W-BM offer the internal energy to the reactants and enhance the mixture of the leaching process. Furthermore, the residue delivers outstanding activity after 400 °C treatment, requiring only 264 mV overpotential at 10 mA cm −2 and exhibiting a low Tafel slope (77.96 mV dec −1 ). This study proposes a rapid, scalable, and comprehensive recycling strategy for spent LIB cathode powders, with a specific focus on the sustainable recovery of cathode materials, offering critical guidance for industrial applications.

Heavy metal ions are increasingly accumulated in the natural environment due to growing water pollution, causing serious pollution to biological communities. Therefore, it is of great significance to study the qualitative and quantitative adsorption and detection of heavy metal ions in wastewater. Using cellulose nanofibrils (CNF)/chitosan (CS) composite as adsorbent framework, salicylaldehyde ethylenediamine Schiff base (SESB) as fluorescent and colorimetric probe, citric acid (CA) as crosslinking agent, and freeze-drying technology to prepare CNF/CS/CA/SESB composite sponge and membrane. After adsorbing Fe 3+ , the composites changes color from yellow-green to brownish-black under sunlight, and undergoes fluorescence quenching within 17 s under ultraviolet light, enabling highly sensitive, selective and reversible detection towards Fe 3+ . The composite sponge exhibits amphiphilicity and a underwater oil contact angle of 154°, which endows it with anti-fouling properties underwater. Its adsorption capacity is 438.68 mg·g −1 , and it has excellent underwater compressive elasticity as well as fluorescence and colorimetric reversibility, providing significant foundation for its application in water purification and collection. The composite membrane can be wide applied in information encryption and anti-counterfeiting fields. Predictably, CNF/CS/CA/SESB composites will offer theoretical reference for the assembly strategy of cellulose fluorescent probes, as well as their applications in detection and information encryption.

In Fenton-like reactions, the elevation of the spin state of transition metals enhances the redox processes of adsorbed peroxides and improves the oxidative performance. This study reports an easily accessible carbon-supported high-spin cobalt cluster, Co–NCs/C, which demonstrates enhanced kinetics through selective high-valent cobalt-oxo species (Co(IV)═O) generation for peroxymonosulfate (PMS)-induced catalytic oxidation. This catalyst achieves rapid degradation of sulfamethoxazole (SMX) within the modified kinetic rate constant (k-value) of 2001.7, surpassing all previously reported Co-based catalysts. Furthermore, combined experimental characterizations and density functional theory calculations demonstrate the stable size distribution of cobalt clusters anchored on carbon supports. Within a broad size distribution (0–6 nm), these clusters consistently retain high-spin configurations and exhibit excellent catalytic performance in SMX degradation. The tailored electronic structure of the high-spin Co sites enhances the adsorption and activation of PMS, thereby accelerating the degradation process. This work provides a practical and cost-effective strategy for designing high-efficiency catalysts for PMS-based advanced oxidation processes.

Tungsten trioxide (WO3)-based electrochromic film is a promising component of all-solid-state electrochromic devices, which can be used as smart windows to control the indoor temperature and incident solar irradiation. However, its practical application suffers from significant challenges including slow switching kinetics, low cycling stability, and high production costs. To overcome the limitations, a mild chemical bath deposition approach is introduced. Through strategic control of reactants, the thickness of WO3 film and the constituent WO3 nanosheets forming the film can both be systematically regulated. The optimized W2 sample demonstrates remarkable electrochromic performance, achieving an optical modulation amplitude of ΔT = 67.85% at 620 nm along with good cycling stability, which was caused by its well-engineered hierarchical structure featuring a thin film configuration (430 nm) composed of ultrathin nanosheets (39.48 nm). This work points out a new strategy for modulating the optical properties of WO3 electrochromic film through reactants control during a chemical bath deposition process, providing valuable insights for the rational design of high-performance smart windows.

Primary and acquired oxaliplatin (OXA)-resistance remains a major challenge in colorectal cancer (CRC) therapy. In this work, the type-II strigolactam SL 39 was identified as a promising lead compound against OXA-resistant HCT116R cells. Co-treatment of SL 39 with OXA restored its sensitivity to HCT116R cells and inhibited xenograft tumor growth. Mechanistically, SL 39-treatment specifically blocked the autophagosome–lysosome fusion in HCT116R cells without altering lysosomal pH, leading to induction of mitochondrial dysfunctions and lethal accumulation of reactive oxygen species. Additionally, SL 39 also markedly increased lipid peroxidation and suppressed the SLC7A11/GPX4 axis to trigger ferroptosis in HCT116R cells. Combining SL 39 with OXA delivered a one-two punch: OXA causes DNA damage and oxidative stress, while SL 39 prevents stress resolution─shifting resistant cells toward ferroptotic death. These findings establish that SL 39 blocks late-stage autophagy to tip the metabolic balance toward ferroptosis in chemoresistant CRC, which offers a novel approach to overcome late-stage treatment failure.

Hydrogen peroxide (H 2 O 2 ) is a versatile and environmentally friendly oxidant whose industrial production has potentially more sustainable routes. Photocatalyzed H 2 O 2 generation represents a mild and efficient alternative, utilizing solar energy to reduce oxygen. However, how the photooxidation half reactions of hole scavengers affect the overall catalytic performances is largely overlooked. Here, we report that photooxidation half reactions are the real rate-limiting steps and that the choice of hole scavengers vitally affects the overall production rate of H 2 O 2 . The H 2 O 2 formation kinetic constants for 12 hole scavengers are compared with their electrooxidation potentials, calculated orbital energies, and energy gaps. No general correlation is found. Several possibilities are proposed, including the influences of different surface adsorption and surface reaction pathways. Our finding suggests that in practice, it is difficult to choose the right half reaction based on intuition or experiences with other systems. A case-by-case study is needed.

This study describes a wet chemical extraction protocol for measuring the biogenic silica (bSi) in sediments from diverse marine environments. The protocol lists the reagents, materials, equipment, and sample preparation procedures, and provides a detailed explanation of the methods for examining the alkaline-leachable silicon (Si), and calculating bSi content. Although, the protocol was primarily developed for measuring bSi in sediments from the Chinese marginal seas, it was also validated using sediments from the Chesapeake Bay, the Atlantic Ocean, and the Southern Ocean. The protocol can be used to quantify bSi in recently deposited and aged sediments from the Holocene period. The protocol contributes to the ongoing efforts to minimize the methodological bias that exist in bSi quantification and the bSi burial flux evaluation, thereby assisting in our understanding of Si cycling in the modern ocean. • This protocol provides a step-by-step wet chemical extraction procedures and the measurement of dissolved Si in an alkaline solution using spectrophotometer. • This protocol is easy to set up and reproduce, and determines bSi content with high precision. • The protocol can be used to determine bSi in sediments of marginal seas and the open ocean.

Although 13X zeolite is commonly used to remove oxygenates from Fischer-Tropsch oil, it still suffers from limited adsorption selectivity. In this study, glycine was used as a modifier to functionalize 13X zeolite by grafting polar groups, and applied for the removal of oxygenates from Fischer-Tropsch oil. The results indicate that the modified zeolite exhibits a high adsorption capacity for oxygenates. Specifically, the adsorption capacity for butanol, hexanal, and 2-hexanone increased by approximately 90%, reaching 0.60 g·g -1 , 0.36 g·g -1 , and 0.35 g·g -1 . The adsorption capacity for hexanol and octanol increased by approximately 50%. The enhancement in adsorption capacity for carbonyl compounds and long-chain alcohols (such as hexanol, heptanol, and octanol) was particularly notable, with an average increase of about 80%. Mechanistic studies revealed that the adsorption of oxygenates on the modified zeolite is primarily physical adsorption, involving hydrogen bonding interactions and van der Waals forces. The adsorption process can be divided into two stages: surface adsorption and pore diffusion, and is jointly influenced by factors such as zeolite pore size, adsorbate molecular size, and their interactions with the pore channels. This study provides a novel strategy for the removal of oxygenated compounds from Fischer-Tropsch oil.

The strategic significance of lanthanides (Ln) in critical technologies necessitates sustainable extraction methods, yet conventional solvent extraction systems face persistent challenges such as environmental toxicity and limited medium adaptability, highlighting the urgent need for novel platforms that combine high efficiency, environmental compatibility, and broad-spectrum applicability. In this study, we present an innovative eutectic mixture (EM) comprising N, N, N′, N′ -tetraoctyl diglycolamide (TODGA) and di-(2-ethylhexyl)phosphoric acid (HDEHP), which pioneers exceptional extraction performance across all lanthanides in an unprecedentedly wide acidity range (pH 3.0 to 3.0 M HNO 3 ), achieving remarkable single-stage distribution ratios ( D Ln ) of 200–2000. Additionally, such a system demonstrates superior cycling stability and operational versatility under diverse industrial scenarios. Through multiscale characterization techniques, we elucidate for the first time the synergistic “coordination-encapsulation” mechanism: TODGA and HDEHP self-assemble into reverse micellar structures, enabling highly efficient lanthanide enrichment through concerted coordination and spatial encapsulation effects. The modular EM design paradigm and elucidated synergistic mechanism not only establish a transformative framework for low-volatility solvent development but also provide pivotal insights for sustainable rare earth resource recovery. This work advances fundamental understanding of supramolecular assembly in solvent extraction while offering practical solutions for industrial implementation.

CO 2 hydrogenation to methanol emerges as a promising strategy, offering a dual advantage of carbon dioxide fixation and the production of a valuable liquid fuel and chemical feedstocks. However, its industrial application is limited by the high stability of the CO 2 molecule, resulting in low CO 2 conversion and methanol selectivity. In this work, a series of Ce-doped Cu-ZrO 2 catalysts were synthesized by an oxalic acid gel co-precipitation method, and the effect of Ce/Zr molar ratios on catalyst structure and catalytic performance were investigated. Comprehensive characterization techniques, including XRD, N 2 physical adsorption–desorption, HRTEM, H 2 -TPR, XPS, CO 2 /H 2 -TPD and DFT calculation were employed to analyze the influence of Ce doping on oxygen vacancy concentration, surface basicity distribution, electron transfer, and catalytic performance. The results demonstrate that the CC 0.4 Z catalyst (n(Ce)/n(Zr) = 0.4) forms a Ce 0.4 ZrO solid solution structure, significantly enhancing CuO dispersion and generating abundant Cu δ+ -Ce 0.4 ZrO interfacial sites and oxygen vacancies. These features synergistically promote CO 2 /H 2 adsorption and activation while stabilizing Cu + species. Under optimized reaction conditions (260 ℃, 3.0 MPa, 9000 h −1 ), the CC 0.4 Z catalyst exhibits outstanding performance: CO 2 conversion of 14.6 %, methanol selectivity of 74.1 %, and a methanol yield of 10.8 %. Compared to the unmodified catalyst, this represents an increase of 5.8 percentage points in CO 2 conversion and 6.3 percentage points in methanol yield, providing a novel catalyst design strategy for efficient CO 2 conversion.

The development of environmentally friendly, inexpensive, and highly active bifunctional catalysts for water splitting remains a major challenge. In this work, hierarchical bulk porous N–CoTe 1.8 /FeNiTe 2 interfacial catalysts were prepared for the first. The prepared three-dimensional (3D) self-supported nanomaterials exhibited efficient electron transfer and mass diffusion, in addition to the optimization of the electronic structure by N doping and the strong electronic interactions between CoTe 1.8 and FeNiTe 2 at the interface facilitated the rapid electron transfer. The layered and porous microtopography increases the specific surface area of the material accelerating the gas transport. The N–CoTe 1.8 /FeNiTe 2 exhibits excellent catalytic activity for OER and HER. It has low overpotentials of 170 mV and 56 mV at 10 mA cm −2 of current density in 1.0 M KOH. In addition, the Faraday efficiency for hydrogen and oxygen production was close to 100 %. The voltage across the water splitting system is only 1.51 V at 10 mA cm −2 current density and has excellent stability with no degradation in a stability test lasting 100 h at 100 mA cm −2 current density. This work provides a novel concept for the rational design and synthesis of inexpensive non-precious metal telluride-based water splitting electrocatalysts.
