Cellulose biocomposites have emerged as attractive alternatives to fossil-based plastics because of their excellent renewability and biodegradability; however, their water resistance and mechanical properties remain challenging. Herein, a cellulose- containing bioplastic with high a reinforcement content, water stability, and toughness is reported. Lignin-containing cellulose nanofibers (LCNF) were prepared by pretreating eucalyptus wood powder with a deep eutectic solvent and high-pressure homogenization. Then, the pre-synthesized ε-caprolactone oligomers were in-situ polymerized in LCNF. The interaction of LCNF with ε–caprolactone-oligomers in the LCNF-crosslinked polycaprolactone (LCNF-PCL) bioplastic resulted in excellent mechanical properties (tensile strength: 76.59 MPa; toughness: 9.82 MJ m −3 ). The LCNF-PCL bioplastic also demonstrated excellent water stability (wet tensile strength: 34.21 MPa; water absorption: <5 %), thermal stability, and UV protection. This approach may provide a potential method for utilizing lignocellulosic resources to develop environmentally friendly bioplastics with good toughness and water stability.

The effect of concentration and origin of dissolved organic matter (DOM) on acenaphthene (Ace) photodegradation in liquid water and ice was investigated, and the components in DOM which were involved in Ace photodegradation were identified. The DOM samples included Suwannee River fulvic acid (SRFA), Elliott soil humic acid (ESHA), and an effluent organic matter (EfOM) sample. Due to the production of hydroxyl radical ( • OH) and triplet excited-state DOM ( 3 DOM*) which react with Ace, DOM had promotion effects on Ace photodegradation. However, the promotion effects of DOM were prevailed over by their suppressing effect of DOM including screening light effect, intermediates reducing effect and RS quenching effect, and thus, the photodegradation rates of Ace decreased in the presence of the three DOM with concentrations of 0.5–7.5 mg C/L in liquid water and ice. ESHA had higher light absorption and thus had higher screening light effect on Ace photodegradation in liquid water than SRFA and EfOM. At each DOM concentration, ESHA exhibited higher promotion effect on Ace photodegradation than SRFA and EfOM, in liquid water and ice. The binding of Ace with DOM was indicated by decreases in fluorescence intensity of Ace when coexisted with DOM. However, the binding of Ace to DOM played an unimportant role in suppressing Ace photodegradation. The photodegradation behavior of fluorophores in Ace with DOM present in ice was not similar to that in liquid water. C–O, C═O, carboxyl groups O–H and aliphatic C–H functional groups in DOM were involved in the interaction of DOM with Ace. The presence of Ace seemed to have no influence on the photodegradation behavior of functional groups in DOM.

Fat reduction due to heating or cooking is an important issue in a healthy diet. In the current study, pork subcutaneous back fat was treated via microwave heating (MH) within 10—90 s and roasting - steam heating (RSH) within 2—30 min and their dynamic changes of individual adipocytes were explored by using vesicles as a bio-membrane model. The result showed that MH and RSH significantly increased fat loss ( P < 0.05), with the maximum losses being 74.1 % and 65.6 %, respectively. The mechanical strength of connective tissue decreased and then increased slightly. The microstructure demonstrated that MH and RSH treatments facilitated a large outflow of fat, showing that the particle size of the vesicle and individual adipocytes increased and then decreased. It is thus feasible to study the dynamic changes of individual adipocytes in regulating fat reduction using cell membrane simulation.

Polymerization-based abatement of phenolic pollutants triggered by thermally activated sodium peroxydisulfate (PDS) is an effective remediation approach characterized by low oxidant consumption but restricted by narrow reaction conditions and risk of overoxidation of the organics. In particular, the polymerization is ineffective for recalcitrant phenolics and at low temperature, low initial concentration of phenolics, and high PDS dosage. The present contribution demonstrates that adding ferric chloride significantly enhances the removal efficiency, polymerization ratio, and PDS utilization efficiency, especially under the unfavorable conditions mentioned above. In the FeCl3-enhanced heat/PDS system, polymerization is promoted by iron-phenolic complexes, which favor the generation of more stable radical monomers through ligand to metal charge transfer. The ferrous ions thereby formed can accelerate PDS activation, thus synergistically contributing to polymerization. In comparison to the conventional mineralization-based advanced oxidation technologies, this process exhibits significantly higher oxidant utilization efficiency under a broad range of conditions, reducing PDS consumption by 85% when used for the treatment of real coking wastewater. Results highlight the great potentiality of this technology for the removal of phenolic pollutants and bring fundamental insights for low-carbon emission and sustainable remediation of industrial wastewater.

Our previous research revealed that human milk fat substitute (HMFS) affects hepatic lipid metabolism in mice, but knowledge concerning its in vivo digestion and metabolism is limited. An in vitro infant digestion simulation and an in vivo metabolism model using Sprague Dawley rats were conducted in this study. In the in vitro model, HMFS showed better digestibility than blended vegetable oil (BVO) or blended vegetable oil plus 1,3-dioleoyl-2-palmitoyl-glycerol (BVO + OPO). In in vivo metabolism experiments, the serum concentrations of unsaturated fatty acids (C18:1 and C18:2) were markedly higher in HMFS than in BVO and BVO + OPO groups. In vivo imaging analysis confirmed that emptied from the gastrointestinal tract significantly faster than BVO and BVO + OPO. These findings suggest that incorporating HMFS in infant formula may enhance nutrient absorption and support infant development.

As an important chemical reagent, methoxy polyethylene glycol amine (mPEG-NH 2 ) is widely used in biomedical field. Unraveling the pharmacokinetic behavior of mPEG-NH 2 polymers is essential for revealing the toxicity and efficiency of mPEG-NH 2 related drug delivery systems. In this study, a simple analytical assay based on mass spectrometry (MS) was first established and validated for quantification of mPEG 5 -NH 2 in biological matrix. The multiple reaction monitoring (MRM) transitions at m / z 252.2 (precursor ions) → 87.7 (fragment ions) and m / z 371.2 (precursor ions) → 89.2 (fragment ions) were chosen to determine mPEG 5 -NH 2 and OH-PEG 8 -OH, respectively. The UHPLC-MS/MS assay showed excellent linearity over the range of 0.01–10 μg/mL. Intra-day and inter-day accuracies and precisions of the assay were all within ± 6.44 %. The analytical assay was successfully applied to reveal the in vivo pharmacokinetic behavior of mPEG 5 -NH 2 in rats.

Currently, photodynamic therapy (PDT) is restricted by the laser penetration depth. Except for PDT at 1064 nm wavelength excitation, the development of other NIR-II-activated nanomaterials with a higher response depth is still hindered and rarely reported in the literature. To overcome these problems, we fabricated a nanoplatform with heterostructures that generate reactive oxygen species (ROS) and ferrite nanoparticles under a high concentration of zinc doping (ZnxFe3–xO4 NPs), which can achieve oxidative damage of tumor cells under near-infrared (NIR) illumination. The recombination of photoelectrons and holes has been markedly inhibited due to the formation of heterostructures in the interfaces, thus greatly enhancing the capability for ROS and oxygen production by modulating the single-component doping content. The efficiency of PDT was verified by in vivo and in vitro assays under NIR light. Our results revealed that NIR-II (1208 nm) light irradiation of ZnxFe3–xO4 NPs exerted a remarkable antitumor activity, superior to NIR-I light (808 nm). More importantly, the reported ZnxFe3–xO4 NPs strategy provides an opportunity for the success of comparison with light in the first and second near-infrared regions.

Nonlinear optical (NLO) crystals capable of controlling and manipulating light to generate coherent radiation at a variety of difficult-to-access wavelengths are essentially crucial for many high-tech applications, yet the rational design of NLO crystals with high-performance remains a great challenge. Herein, inspired by two facts, namely, hetero-anionic structures can effectively integrate the diverse property superiorities of single-anions, and T2-type supertetrahedra can exhibit enhanced polarizability compared to simple tetrahedra. We assembled multiple different [TS 4 ] (T = Zn, Sn) tetrahedra to form the hybrid T2-type supertetrahedra and successfully synthesized new hybrid T2-type supertetrahedral IR NLO crystals, Ae 5 Zn 3 Ga 2 Sn 2 S 15 (Ae = Sr and Ba), both of which exhibit intriguing NLO properties, including strong second harmonic generation responses (2.8 × AgGaS 2 –3.0 × AgGaS 2 ), wide band-gaps (2.81–2.89 eV), high laser-induced damage thresholds (∼15 × AgGaS 2 ), a broad IR transmission range (up to 14 µm), and suitable birefringence (0.048–0.051@1064 nm). More significantly, both exhibit congruent melting behavior, and a high-quality single crystal of Ba 5 Zn 3 Ga 2 Sn 2 S 15 with centimeter-level has been successfully grown using the Bridgman method. These findings strongly suggest that Ba 5 Zn 3 Ga 2 Sn 2 S 15 holds great promise as an IR NLO crystal, and the strategy for constructing hybrid T2-type supertetrahedra is effective for designing novel high-performance NLO crystals.

Nowadays, effluent treatment is a severe challenge mainly because of its complex composition, which includes oil, heavy metal ions, and dyes. Developing new intelligent membranes is one of the strategies to tackle these significant challenges in wastewater treatment . In this study, we fabricated asymmetric polyethylene glycol terephthalate (PET) membranes by grafting cross-linked poly (itaconic anhydride) (CL-PITA) nanoparticles onto the irradiated face. These nanoparticles were then functionalized with polyethyleneimine (PEI) and protonated with HCl to introduce numerous active electropositive amine groups. The fundamental purpose was to increase surface roughness, introduce numerous hydrophilic groups, and modify it to create a multi-functional PET membrane to separate complex environments. The promising results demonstrated that the protonated PET- g -ITA/DVB (10) -cat membrane exhibited excellent separation efficiencies (SE) for water/light oil, water/heavy oil and oil-in-water (O/W) emulsion. Compared to PET- g -ITA/DVB (0) -cat, it showed superior performance in SE for O/W emulsion and flux decay for water/light oil after 10 cycles. More interestingly, owing to numerous positively charged active amino groups and negativley charged carboxylate groups, the intelligent membrane exhibited a high removal rate of ca. 90 % for anionic dye (congo red) and heavy metals (Cu 2+ and Co 2+ ), showing great potential in complex water treatment environments.

Protonic Ceramic Electrolysis Cells (PCECs) enable the in situ production of hydrogen and protons via steam electrolysis, positioning them as promising reactors for environmentally friendly ammonia synthesis. However, the efficiency and stability of this process are currently constrained by the limited catalysis activity and the aggregation of conventional fuel electrodes. Herein, in situ formed Fe-Co-Ni alloy nanoparticle catalysts are designed, and find that these alloy sites significantly enhance N 2 adsorption. Selective impregnation of Fe-Co and Ni exsolution is integrate to promote the in situ formation of Fe-Co-Ni alloy catalytic sites within the fuel electrode of tubular PCECs (10 cm 2 active area). Under an applied voltage of 0.6 V, the in situ alloyed PCEC reactor reaches 2.37 × 10 −8 mol s −1 NH 3 synthesis rate at 600 °C, which is 2.1 times that of with common fuel electrode. Density functional theory calculations further reveal that alloying reduces the activation energy for nitrogen hydrogenation, thereby facilitating the reaction pathway. Moreover, the in situ formed alloy sites exhibit a strong anchoring effect, effectively preventing catalyst aggregation at high temperature and enabling stable, efficient ammonia synthesis over 250 h. This study demonstrates the significant potential of in situ alloy catalysts combined with tubular PCECs for electrochemical ammonia synthesis.

In alpine meadow regions, macropore flow is a critical but inadequately understood pathway for antibiotic transport. The complex relationship between macropore structure, flow dynamics, and solute properties presents a significant research gap. Methodological limitations hinder the accurate characterization of solute migration mechanisms due to complex macropore structures. This study investigated sulfadiazine (SD) and florfenicol (FF) migration behaviors in alpine meadow soil using leaching experiments in soil columns with artificially constructed macropores. Findings reveal that while greater macropore flow intensity (> 1.75 cm/h) and connectivity accelerate solute transport, the effect is not linear. A fundamental shift in transport control occurs with changing macropore flow intensity. At lower velocities, solute mobility is primarily controlled by adsorption reactivity, particularly for the strongly reactive SD. Conversely, at high velocities, hydrodynamic dispersion becomes the dominant factor governing the transport. Moderate dispersion (1.7–1.8 cm 2 /h) optimizes retention by increasing adsorption opportunities, while high dispersion (3.06 cm 2 /h) accelerates solute transport and reduces retention. This causes the transport of the strongly reactive SD to become dispersion-driven, significantly narrowing the behavioral differences between it and the weakly reactive FF. This highlights that under certain hydraulic conditions, physical transport processes can override chemical properties in controlling contaminant fate.

Metabolic health is a major global health challenge associated with increased risks of disability, cancers, premature deaths, and a negative impact on patient quality of life. Precise monitoring of biomarkers in human urine, including metabolites and electrolytes, provides crucial guidance for treatment. While rich impurities in urine will induce cross-interference of the biosensors array, making continuous and reliable analysis of multiple biomarkers challenging. To address these issues, a multiplexed and in situ self-calibrated biosensing system (MSSCBS) is proposed with remarkably high stability and sensitivity in untreated urine samples. These desirable characteristics are achieved through the design of multiple electrochemical channels with self-assembled nanostructure and an in situ bio-signals self-calibration method of dynamic normalized least mean squares. MSSCBS delivers reliable sensitivities (e.g., 0.04 µA/µ m for uric acid), a wide linear range (e.g., 0.2–23.6 m m for glucose), and long-term stability (>20 days) of urinary impurities. Combination with a customized circuit for signal processing and wireless data transmission to mobiles supports convenient and long-term continuous monitoring of urine. This study validates MSSCBS's usability in assessing metabolic states in healthy participants and patients with diabetes, kidney disease, showing the potential of at-home biosensing platform for healthcare applications.
