Photocatalytic hydrogen production with simultaneous degradation of organic pollutants by using solar energy provide a promising strategy to solve the energy and environmental issue in the future. However, for onefold wide band-gap semiconductor, the poor photocatalytic efficiency limits its application on a large scale due to its easy recombination of photo-generated electron-hole pairs and low solar energy utilization. Herein, a novel Z-scheme BiVO 4 (040)-Bi-(NaYF 4 :Er,Yb,Tm@BiOBr)/Bi photocatalyst is prepared via photo-assisted isoelectric point method. In this composite photocatalyst, up-convention luminescence material, NaYF 4 :Er,Yb,Tm, can offer more ultraviolet light and visible light to intensify the activations of BiOBr and metal Bi nanoparticles, respectively. Furthermore, the formation of Z-scheme BiVO 4 (040)-BiOBr photocatalystic sytem, the spatial separation of the BiVO 4 (040) and BiVO 4 (110) facets and the presence of metal Bi surface plasmon resonance effect are contributed to the high-efficiency separation of the photo-generated electron-hole pairs. The experimental results show that as-prepared Z-scheme BiVO 4 (040)-Bi-(NaYF 4 :Er,Yb,Tm@BiOBr)/Bi photocatalyst exhibits advanced photocatalytic hydrogen production amount (192.0 μm) and excellent degradation ratio of malachite green (88.51 %) under simulated sunlight irradiation for 5.0 h. The apparent quantum yield of the Z-scheme BiVO 4 (040)-Bi-(NaYF 4 :Er,Yb,Tm@BiOBr)/Bi photocatalyst at 420 nm reaches a specific value of 5.8 %. In addition, Z-scheme BiVO 4 (040)-Bi-(NaYF 4 :Er,Yb,Tm@BiOBr)/Bi photocatalyst also remains a high stability in the photocatalytic hydrogen production with simultaneous degradation of malachite green within six reuse. At last, the possible reaction mechanism and degradation pathways of malachite green caused by Z-scheme BiVO 4 (040)-Bi-(NaYF 4 :Er,Yb,Tm@BiOBr)/Bi photocatalyst under simulated sunlight irradiation are put forward.

To improve the visible-light photocatalytic activity and photo-carriers separation of BiVO 4 , highly efficient Z-scheme structured visible-light photocatalyst Ag@AgBr/BiVO 4 /Co 3 O 4 was constructed by selective doping of Ag@AgBr and Co 3 O 4 on {010} and {110} facets of BiVO 4 . Due to the different energy levels of conduction band (CB) and valence band (VB) between {010} facet and {110} facet, BiVO 4 could act as the ‘pre-separation channel’ to achieve spatial charge separation. Such pre-separation channel effect improved photo-electrons transfer from BiVO 4 {010} facets to electron mediator (Ag°) for subsequent recombination with holes of AgBr. Thus, the photo-induced electrons of AgBr could be accumulated on CB for reduction of O 2 to O 2 − . On the other hand, holes of BiVO 4 accumulated on {110} facets were captured by deriving-hole-type co-catalysts Co 3 O 4 for organics oxidation. In addition, Ag° not only served as the electron mediator of Z-scheme but also improve the visible-light utilization due to SPR-effect. Being attributed to the synergistic effect of pre-separation channel and deriving-hole-type co-catalysts, Z-scheme structured Ag@AgBr/BiVO 4 /Co 3 O 4 (0.15 wt%) achieved high photodegradation rate of organics. Even after 9th cycles, Ag@AgBr/BiVO 4 /Co 3 O 4 (0.15 wt%) could still photodegraded more than 90% of OTC within 24 min. DRS, PL and photoelectrochemical analyses also confirmed the improvement of visible-light utilization and charge separation of Ag@AgBr/BiVO 4 /Co 3 O 4 . The radical trapping experiments and EPR demonstrated that both superoxide radical ( O 2 − ) and holes (h + ) were main active species for organics photodegradation. In summary, this work not only constructed a highly efficient Z-scheme structured visible-light photocatalyst, but also provided a new method to diminish the photo-carriers recombination by pre-separation channel and hole-sink effects.

Although Bi-based compounds are effective photocatalysts for degrading organic pollutants under visible-light irradiation, their visible-light photocatalytic activities are still low and far from practical application. In this study, novel graphene-functionalized Bi-bridge Z-scheme black BiOCl/Bi 2 O 3 (black BiOCl-Bi-Bi 2 O 3 /rGO) heterojunctions with oxygen vacancies were prepared via in situ Fe reduction of BiOCl/graphene oxide nanoplates. In comparison with BiOCl/graphene oxide nanoplates, the black BiOCl-Bi-Bi 2 O 3 /rGO heterojunctions have stronger visible-light absorption, and exhibit more efficient charge separation and higher visible-light photocatalytic activity in degrading 2-nitrophenol (2NP). The black BiOCl-Bi-Bi 2 O 3 /rGO 0.4 shows the highest visible-light photocatalytic activity with almost complete degradation of 2NP, which is attributed to proper bandgap match between black BiOCl and Bi 2 O 3 , multiple charge transfer channels via Bi-bridge and rGO, and efficient charge separation. Of special importance, black BiOCl-Bi-Bi 2 O 3 /rGO heterojunction can effectively treat real industrial wastewater with 70.3% COD removal efficiency, and it shows superior long-term stability. Additionally, a possible photocatalytic mechanism of black BiOCl-Bi-Bi 2 O 3 /rGO heterojunctions based on multiple charge transfer channels was proposed.

Nowadays, simultaneous removal of organic pollutants and heavy metals from wastewater is still a complicated task with great challenge. Herein, a newly-designed Fe-g-C 3 N 4 /α-Fe 2 O 3 composite with an active N-Fe-O bridge was prepared by coupling Fe-doped g-C 3 N 4 (namely Fe-g-C 3 N 4 ) and α-Fe 2 O 3 . Interestingly, the combination of Fe-g-C 3 N 4 with α-Fe 2 O 3 broadened the light absorption region and restrained the photoinduced electron-hole pair recombination. Meanwhile, elaborate construction of N-Fe-O bridges based on coordination interaction can reduce electrochemical impedance and facilitate electron transfer, thereby prolonging the charge lifetime. As expected, the Fe-g-C 3 N 4 /α-Fe 2 O 3 composite displayed excellent photocatalytic performance in simultaneous removal of tetracycline (TC) and Cr(VI). More importantly, Fe-g-C 3 N 4 /α-Fe 2 O 3 -mediated electron transfer from TC to Cr(VI) also played an essential role on TC oxidation and Cr(VI) reduction under visible light. Both experimental analyses and theoretical calculations revealed that the migration route of photogenerated carriers followed a direct Z-scheme heterojunction mechanism under built-in electric field. The Fe-g-C 3 N 4 /α-Fe 2 O 3 composite with great stability also displayed promising practical application potential. In short, the current work not only provided a highly-efficient photocatalyst with N-Fe-O bridges but also shared new insights into the simultaneous removal of organic pollutants and heavy metals.

Highly active Fe 3 O 4 /GO/Au composite nanomaterial was fabricated as a substrate of surface-enhanced Raman spectroscopy (SERS) and applied for pesticide residue detection. The three-layer multifunctional Fe 3 O 4 /GO/Au nanoparticles (NPs) were designed by facile method, with high hotspots, and were characterized by various techniques, including ultraviolet spectrophotometry (UV), X-ray diffraction (XRD), infrared absorption spectrometer (IR), and transmission electron microscopy (TEM). The performance of Fe 3 O 4 /GO/Au was evaluated by Raman spectroscopy with R6G as a probe molecule to verify its enhancement effect. It exhibited a strong Raman signal with 10 −6 M of R6G. Furthermore, the presence of Fe 3 O 4 /GO/Au nanohybrid enabled the SERS-based method to detect mancozeb and showed an excellent linear relationship in the range of 0.25–25 ppm, with a low limit of detection (0.077 ppm), satisfactory EF, stability, and repeatability. In addition, the mechanism of SERS enhancement with electromagnetic mechanism (EM) and chemical mechanism (CM) was discussed in detail. Therefore, the proposed SERS approach holds promise as an auxiliary technique for screening contaminated agricultural products, environmental sample, and food in the future.

The lithium-phosphorus-thiohalides (LPS X ) with superionic conduction are strong candidates for the new-generation solid electrolytes (SEs) in all-solid-state lithium-ion batteries (ASSLIBs). In this work, Li 6− x PS 5− x Cl 1+ x − y Br y (LPSCB; 0 ≤ x ≤ 0.7; 0 ≤ y ≤ 1.7) was synthesized by a solid-state method in which the key raw material of Li 2 S was prepared by an improved carbothermal reduction method without late decarbonization. The lattice flexibility and the degree of structural order are opposite effect and would lead to an optimum of the ionic conductivity at a composition of LPSCB. Li 6 PS 5 Br- and Li 5.5 PS 4.5 Br 1.5 -based ASSLIBs had the best rate capacity and cycle performance in Li 6 PS 5 Cl 1− y Br y - (0 ≤ y ≤ 1) and Li 5.5 PS 4.5 Cl 1.5− y Br y -based ones (0 ≤ y ≤ 1.5), respectively. To increase the ionic conductivity of LPSCB-type SEs and capacity/cycle performance of the related ASSLIBs, Br-introduction, mutual substitution and excess- X substitution were extremely effective strategies.

Wet age-related macular degeneration (Wet AMD) is a major cause of vision loss and has been linked to abnormal choroidal neovascularization (CNV). Current therapies require frequent intravitreal injections, which leads to poor patient adherence. Herein, this study was designed to investigate rapamycin-loaded chitosan-coated poly(lactic-co-glycolic acid) nanoparticles, which represent a sustained-release drug delivery system for wet AMD. The Rap@CS/PLGA NPs were synthesized using emulsion solvent evaporation, followed by coating with chitosan. The obtained Rap@CS/PLGA NPs exhibited a size of 265.9 ± 6.30 nm and encapsulation efficiency (EE) of 60.30 ± 1.20%. The drug release profile showed a biphasic pattern with reduced initial burst release (6 ± 0.6%) followed by sustained release (46 ± 4.1%) over 72 h, which indicates improved delivery control. In vitro cytotoxicity on ARPE and HUVEC cells showed minimal toxicity, with more than 85% viability at dosages up to 100 μg/mL. In vivo anti-angiogenic assays using the chick chorioallantoic membrane (CAM) model showed that the Rap@CS/PLGA group (13 ± 3 vessels) significantly reduced the vessel formation vs Rap (26 ± 2 vessels), confirming superior anti-angiogenic effects. Moreover, the laser-induced CNV mouse model, Rap@CS/PLGA NPs, significantly reduced levels of inflammatory cytokine (TNF-α and IL-6) and restored antioxidant enzyme (SOD, CAT). This showed that protection against oxidative stress in CNV-affected tissue promotes angiogenic gene expression (VEGFA, CCL2), while preserving retinal structure. These findings propose that Rap@CS/PLGA NPs can effectively and control drug delivery for wet-AMD with long-lasting efficacy. Graphical

Protein glycosylation is a major post-translational modification that regulates tumor initiation and progression; however, its dynamic modeling during multistep evolution of lung adenocarcinoma (LUAD) remains poorly understood, particularly in clinically archived tissues. Here, we established an integrated multi-omics workflow combining global proteomes, N-glycans, and site-specific intact N-glycopeptides to comprehensively characterize glycosylation in formalin-fixed paraffin-embedded (FFPE) specimens spanning four pathological stages of LUAD progression: inflammatory nodules (IN), atypical adenomatous hyperplasia (AAH), adenocarcinoma in situ (AIS), and invasive adenocarcinoma (IAC). Using optimized protein extraction, hydrophilic interaction liquid chromatography (HILIC)–based glycopeptide enrichment, and high-resolution LC–MS/MS, we achieved large-scale identification of proteins, N-glycans, and intact glycopeptides from archival clinical samples. Integrated analyses revealed progressive remodeling of site-specific N-glycosylation during malignant transformation, characterized by increased glycan branching, fucosylation, and sialylation during the transition from premalignant lesions to invasive cancer. Sialylated glycans reached their highest abundance in the premalignant AAH stage, whereas highly branched and fucosylated complex N-glycans predominated in invasive adenocarcinoma, indicating stage-dependent glycan remodeling throughout disease progression. Functional enrichment analyses linked these glycosylation alterations to extracellular matrix organization, neutrophil degranulation, and immune-associated pathways, while representative glycoproteins, including CEACAM6 and FGB, exhibited coordinated changes in protein abundance and site-specific glycoform micro-heterogeneity across pathological stages. Collectively, this study demonstrates the feasibility of deep glycoproteomic profiling using archived FFPE tissues and provides a comprehensive molecular atlas of glycosylation remodeling during LUAD progression. These findings establish a valuable resource for elucidating disease mechanisms and identifying stage-specific glycosylation biomarkers and potential glycan-targeted therapeutic candidates for early lung adenocarcinoma.

Cellular mechanics play significant roles in biological processes from cellular level to tissue level. Great efforts have been committed to developing simple and reliable mechanical sensing strategies. Here, we present the concept of cellular mechanics displaying on visual structural color hydrogel microcolumn arrays. The microcolumn arrays were fabricated by using colloidal crystal pregel to hierarchically replicate microwell array templates. With the cultivation of beating cardiomyocytes, the microcolumn arrays could occur synchronous and reversible deformations, accompanied with visible structural color changes and reflection peak shifts for cellular mechanics displaying. Benefitting from this principle, together with the similar dimension with cells, the structural color microcolumn arrays could self-report the contraction force of cardiomyocytes at single-cell level. Based on these features, we have established a myocardial hypertrophy model in microfluidic systems and verify the value of the structural color hydrogel microcolumn arrays in monitoring the mechanical behaviors of cardiomyocytes under pathological conditions. Thus, we believe that the proposed structural color hydrogel microcolumn arrays and their integrated chips are suitable for evaluating clinical diseases of aberrant cellular force and even providing possible therapeutic targets.

A multifunctional liposomal hydrogel nanoplatform (CMH@lip@Res-TCeO 2 ) was developed for the targeted treatment of psoriasis-like skin inflammation through combined antioxidant and anti-inflammatory mechanisms. The system integrates resveratrol (Res) and mitochondria-targeted cerium oxide nanozymes (TPP-CeO 2 ) within a thermo-responsive hydrogel matrix, enabling sustained transdermal delivery and enhanced local drug retention. Network pharmacology and transcriptomic analyses identified 36 key targets and highlighted the ROS/mTOR/HIF-1α axis as a critical pathway in neutrophil regulation. Single-cell RNA sequencing revealed fibroblasts, keratinocytes, and neutrophils as key cellular contributors to psoriasis pathogenesis. CMH@lip@Res-TCeO 2 effectively suppressed mitochondrial reactive oxygen species (ROS) accumulation, inhibited mTOR/HIF-1α activation, reduced neutrophil extracellular trap (NET) formation, and alleviated keratinocyte dysfunction. In IMQ-induced psoriasis-like mice, the treatment significantly decreased inflammatory cytokine expression and improved histopathological features. These findings demonstrate that CMH@lip@Res-TCeO 2 exerts multi-level regulation of oxidative stress, metabolism, and inflammation, offering a promising nanotherapeutic strategy for psoriasis and other chronic inflammatory skin disorders.

Ether-based electrolytes have shown great success for lithium metal electrodes 1 , 2 , 3 , 4 , 5 . However, during the charging process of high-voltage full cells, the desolvation of solvents and anions to accommodate Li ions released from the positive electrode exacerbates oxidative decomposition of the electrolyte 6 . In addition, the continuous consumption of components over extended cycling substantially alters the solvation structure, resulting in deteriorating redox stability. Here we incorporate a targeted ligand anti-solvent (TLAS) into an anion-rich ether-based electrolyte. The TLAS barely participates in the solvation of Li + owing to its relatively weaker association ability in a static state. Under the strong electric field of high-voltage full cells, the orientation and distribution of the TLAS undergo substantial transformation, with coordination ability activated on the positive electrode surface. The TLAS-mediated dynamic solvation behaviour bypasses the inherent decoordination and recoordination of solvents and anions on the positive electrode in conventional electrolyte systems, thus minimizing electrolyte reconstruction and interphase deterioration. Leveraging this gradient solvation electrolyte, we develop a 450 Wh kg −1 lithium metal pouch cell that achieves a long cycle life exceeding 750 cycles (80% capacity retention). Furthermore, we validated a lithium metal pouch cell with a high energy density of 605 Wh kg −1 , which achieves 150 cycles with 96% capacity retention. This gradient solvation strategy provides a feasible pathway of electrolyte engineering for metal-ion batteries.

We developed an on-site surface-enhanced Raman scattering (SERS) sensor for rapid detection of difenoconazole (DIF) and flusilazole (FLU) in environmental water. The substrate combines gold nanostars (AuNSs) with covalent organic frameworks (COF) and is implemented on a portable round 20-well quartz plate, enabling in situ testing. After a simple filtration process, environmental water can be directly dripped onto the SERS-active AuNSs/COF composite, thereby simultaneously achieving the adsorption of the target compound and SERS detection. There is a good linear relationship between the SERS intensity of the characteristic peak and the logarithmic concentration of the analyte, with correlation coefficients (R 2 ) from 0.923 to 0.986, meeting the monitoring needs of non-laboratory scenarios. The entire workflow completes within 9 min, offering a faster alternative to conventional methods while maintaining high sensitivity and reproducibility. Detection limits reach 0.88–1.17 ppb for DIF and FLU. Distinct SERS fingerprints enable reliable discrimination of mixed pesticides across environmental water, supporting rapid on-site monitoring and cost-effective pesticide surveillance. Graphical
