Hydrothermal synthesis of Bi-Bi 3 TaO 7 heterostructures with mannitol • Morphological evolution from nanoflakes to nanoparticles • Enhanced visible absorption and charge separation by modulation of d-band center • Photocatalytic performance of nitrogen fixation up to 10 times that of pristine Bi 3 TaO 7 Morphology control can effectively regulate the interfacial electric field and electronic structure of photocatalytic materials, making it an important strategy for achieving efficient nitrogen fixation. In this study, a facile one-step hydrothermal method is used, with mannitol as both a reducing agent and morphology regulator, to in situ deposit metallic bismuth nanoparticles onto the surface of Bi₃TaO₇ (BTO), forming Bi-Bi₃TaO₇ (Bi-BTO) Schottky heterojunctions. The Bi-BTO samples consist of nanoparticles as compared to nanosheets for pure BTO, which not only increases the specific surface area and accessibility of catalytic active sites but also effectively regulates the interfacial contact of the Schottky heterojunction. This strengthens the built-in electric field and shifts the d-band center closer to the Fermi level. The optimized electronic structure enhances orbital coupling between the catalyst and nitrogen molecules, promoting nitrogen adsorption and activation and lowering the energy barrier for the formation of the rate-determining *NNH intermediate. Thanks to the synergistic effect of morphology engineering on the built-in electric field and d-band center, the optimal sample Bi-BTO-2 shows an excellent photocatalytic nitrogen fixation performance even without a hole scavenger, achieving an ammonia generation rate of 195 μmol·g −1 ·h −1 , 10 times that of pure BTO, with ammonia selectivity approaching 100%. This study highlights the key role of morphology engineering in regulating the interfacial properties and electronic structure of Schottky heterojunctions, providing a practical modification strategy for the design and engineering of high-performance photocatalysts for nitrogen fixation.

Zr 4+ incorporation drives a complete transition to an amorphous phase and increases the electrochemically active surface area. • Zr 4+ incorporation induces a downward shift in the core-level binding energies of Fe, Co, and Ni sites. • Optimized S-CrMnFeCoNiZr 1.5 specimen achieves overpotentials of 240/287 mV at 10/100 mA/cm 2 . • S-CrMnFeCoNiZr 1.5 specimen exhibits outstanding stability and a 16-fold enhancement in TOF relative to S-CrMnFeCoNi specimen. Developing efficient and durable electrocatalysts for oxygen evolution reaction (OER) is pivotal to advancing renewable energy conversion technologies. Herein, a series of amorphous CrMnFeCoNi-based high-entropy compounds (HECs) with varied Zr content were synthesized, and the role of Zr doping in modulating the atomic/electronic structures were investigated, as well as the OER activity. Experimental characterization reveals that Zr 4+ incorporation drives a complete transition to an amorphous phase, increases the electrochemically active surface area, and induces a downward shift in the core-level binding energies of Fe, Co, and Ni. Relative to the Zr-free analogue, the optimized catalyst S-CrMnFeCoNiZr 1.5 delivers a 57/69 mV reduction in overpotential at 10/100 mA cm −2 , exhibits a 17-fold higher turnover frequency, and maintains exceptional operational stability over 72 h. This OER activity outperforms most previously reported HECs. Density functional theory calculations corroborate these observations, demonstrating that Zr doping upshifts the d-band centers of Fe, Co, and Ni, thereby strengthening adsorption of intermediates and optimizing the free-energy profile for the rate-determining steps. Collectively, this study establishes a rigorous structure–electronic property–performance correlation and demonstrates Zr-mediated electronic modulation as a rational, scalable strategy for engineering high-entropy electrocatalysts.

Background and aim Platycodin D (PD), a major bioactive saponin isolated from the traditional Chinese medicine (TCM) Platycodon grandiflorus , has shown promising therapeutic potential against non-small cell lung cancer (NSCLC). However, the functional mechanisms of PD in NSCLC progression remains unclear. This study aimed to explore the pharmacological mechanism of PD against NSCLC. Materials and methods Thermal proteome profiling (TPP) approach, molecular docking, cellular thermal shift assay (CETSA) and peptide-centric local stability assay (PELSA) were employed to identify the potential binding target of PD. Subsequent Western Blot and immunoprecipitation-Western Blot (IP-WB) experiments were conducted to investigate the downstream signaling pathways of the target. Furthermore, proteomic and ubiquitinomic profiling of PD-treated cells were performed to investigate its functions on global. Results Replication factor C subunit 4 (RFC4) was identified as a potential binding target of PD by TPP and their binding sites were further exposed by PELSA. PD-RFC4 complex promotes the degradation of Notch1 and Notch3 by reducing nuclear entry of their domains. Compared with control treatment, the differentially expressed proteins induced by PD were found to be primarily involved in ferroptosis, ubiquitination, platinum drug resistance and ribosome-related processes. The ubiquitin proteome analysis revealed that proteins associated with the Notch pathway underwent ubiquitin modifications. Conclusions PD binds to RFC4 and inhibits its activity, leading to downregulation of the Notch signaling pathway, ultimately triggering cancer cell apoptosis. PD is a natural product with potential therapeutic value for NSCLC.

Orthokeratology (OK) lenses for myopia correction are susceptible to biofouling by tear-derived biomolecules, escalating the risks of ocular infection and inflammation. Prevailing studies that rely on end point protein quantification fail to capture the real-time kinetics of fouling formation. Here, we fabricated a UV pressure-assisted polymer-grafted quartz crystal microbalance with dissipation monitoring (QCM-D) sensor exhibiting exceptional stability, nanoscale smoothness (RMS roughness ≈2 nm), and interfacial peel resistance. This platform enables in situ tracking of adsorption/desorption kinetics for four critical tear components: native/denatured lysozyme and oxidized/native lecithin. Key findings reveal a flow-dependent fouling behavior, wherein low flow rates increase biomolecule adsorption by 37–80% compared with higher flows. We further identify denatured lysozyme and native lecithin as resilient contaminants characterized by a stronger deposition affinity and pronounced resistance to elution. Quantitative screening of multipurpose solutions (MPSs) demonstrates that MPS #2 achieves 20–100% elution rate across biomolecules, outperforming commercial benchmarks. By leveraging dissipation–frequency (D–F) analysis, we clarify the fundamental mechanisms of biofouling formation at the molecular level. Collectively, this work establishes three critical advances: (1) a real-time biofouling diagnostic platform for OK lens interfaces, (2) molecular design principles for antifouling materials based on adhesion remodeling theory, and (3) an accelerated MPS formulation screening paradigm for ocular device safety.

The rise of multidrug-resistant bacteria, especially methicillin-resistant Staphylococcus aureus (MRSA), poses a serious threat to human health, necessitating an urgent need to develop innovative antibacterials with multifunctions for this. Here, focusing on integrating multi-antimicrobial mechanisms with visual monitoring, we report a novel phenanthro[9,10-d]imidazole fluorogen 9b, outstanding for its antibacterial effects against S. aureus and various clinical MRSA isolates (minimum inhibitory concentration = 0.5 to 1 μg/ml) with rapid bactericidal activity, high membrane selectivity, and low susceptibility to drug resistance. Further investigation revealed its dual antimicrobial mechanisms of action by concurrently disrupting bacterial cell membranes and inducing bacterial DNA degradation to accelerate bacterial death. Ultraviolet–visible and fluorescence spectroscopy studies showed that the fluorescence intensity of 9b was dramatically enhanced when it interacted with S. aureus. Notably, in vivo studies demonstrated that 9b effectively treated both skin and thigh MRSA infections, showing a favorable safety profile and superior efficacy compared to the first-line antibiotic vancomycin. The “dual-mechanism” fluorescent phenanthro[9,10-d]imidazole fluorogen 9b holds promise as a candidate for developing innovative antibacterial agents that enable simultaneous real-time diagnosis and treatment.

A novel phospholipid derivative, PA-CG, is synthesized via a PLD-catalyzed method. • Success of PA-CG synthesis is structurally confirmed by NMR and MS analysis. • PA-CG shows superior antioxidant activity to PC and CG in DPPH, ABTS, and FRAP assays. • SPI+PA-CG combination improves the physical and oxidative stability of O/W emulsions. This work presents an efficient enzymatic synthesis of a novel phosphatidyl caffeoyl glycerol (PA-CG) via phospholipase D (PLD)-catalyzed transphosphatidylation of phosphatidylcholine (PC) with caffeoyl glycerol (CG). Under optimized conditions (CG/PC 4:1 mol/mol, water/methyl tert-butyl ether (MTBE) 0.15:1 V/V, PLD 30 U/mL, 40 °C, 3 h), the yield exceeded 95% (HPLC mol% relative to PC), and the product was confirmed by NMR and ESI-MS. PA-CG exhibited additive antioxidant activity over PC and CG in DPPH, ABTS, and FRAP assays. When combined with soy protein isolates (SPI), PA-CG outperformed SPI or SPI+PC in stabilizing oil-in-water (O/W) emulsions, evidenced by the highest emulsifying activity index, smallest and most homogeneous droplets, and lowest creaming index, attributed to its excellent amphiphilic interfacial properties. Moreover, SPI+PA-CG emulsion displayed the slowest increase in peroxide value (POV) and thiobarbituric acid reactive substances (TBARS) over time. Collectively, PA-CG is a promising dual-function antioxidant and emulsifier for food, cosmetic, and pharmaceutical applications.

Reported are the synthesis, material characterization, and electrocatalytic hydrogen evolution reaction (HER) in acid and alkaline electrolytes for the Brewer intermetallic phase, Nb6Co7 and Mo6Co7. It was realized that the overpotential at a current density of 10 mA/cm2 (η10) for Nb6Co7 (η10 = 62 mV) and Mo6Co7 (η10 = 143 mV) are both much lower than that of using a single Co metal (η10 = 253 mV) in alkaline electrolytes. The enhancement of electrocatalytic HER activity of Nb6Co7 and Mo6Co7 can be attributed to the hypo-hyper-d-electronic interaction between Nb/Mo and Co elements. Based on the result of density functional theory calculation, alloying between Nb/Mo and Co elements will increase the antibonding state population of the Co–Co bond near the Fermi level (EF), which induces the synergistic effect to influence the adsorption energy of the H atom (ΔGH) on the surface of Nb6Co7 and Mo6Co7. Moreover, the role of the Nb element is not only a simple electron donor but is also an anchor position for the OH molecule (i.e., dual function) due to the bonding character of the Nb–Co bond near EF. It can reduce the OH position effect as well as the activation energy for water dissociation, which rationalizes the high and robust HER performance of Nb6Co7 to that of commercial Pt/C (η10 = 67 mV) in alkaline electrolytes.

A series of nickel-incorporated SBA-15 mesoporous molecular sieves (Ni-SBA-15) were prepared as support for the immobilization of his-tagged recombinant Microbacterium esterase. The Ni-SBA-15 could strongly and specific absorb the his-tagged esterase from cell disrupted supernatant. It was found that the nickel amount in Ni-SBA-15 has dramatic influence on the activity and thermo-stability of immobilized enzyme, while the kinds of nickel precursor had little effect on enzyme stability. The morphology, chemical composition and structure of the best support NiCl 2 -SBA-15 (Ni-SBA-15 prepared from NiCl 2 precursor) were characterized by various spectroscopy techniques. The immobilized esterase retained full activity of free esterase and showed high immobilized yield (> 90%) with higher thermo-stability, pH stability and organic solvent resistance compared with free enzyme. The optimum reaction temperature increased from 35 to 40 °C and the optimal reaction pH moved from 10.0 to 8.0 after enzyme immobilization. The immobilized esterase exhibited excellent storage stability and keeping 92% of the initial activity after 30 days’ storage at 25 °C. In addition, the immobilized esterase had excellent reusability for the synthesis of key chiral intermediate of d -biotin and the substrate conversion could still keep 100% after 13 cycles continuously. Finally, optical pure (4 S , 5 R )-hemiester was obtained in 80.8% isolated yield and 99% purity in the gram preparative scale.

The effect of ellagic acid on the formation of pyrazine, methylpyrazine, 2,3-methylpyrazine, 2,6-methylpyrazine, 2,5-methylpyrazine, and trimethylpyrazine in the xylose–glycine Maillard reaction model was researched. Ellagic acid could either inhibit or promote pyrazine formation, depending on its addition time point and the pH of the system. The addition of ellagic acid during the accumulation period of an Amadori compound inhibited pyrazine formation by capturing the Amadori compound in the xylose–glycine Maillard system and decreasing the pyrazine precursors. The inhibitory effect of ellagic acid on pyrazine formation got more obvious with an increase in the pH of the system. However, when ellagic acid was added at the beginning of the xylose and glycine Maillard system and when the oxidizing substances such as glyoxal and methylglyoxal were significantly formed in the Maillard system, its oxidation could promote the formation of pyrazines.

Identifying the molecular structures of drugs are important for understanding the molecular interactions between drugs and proteins. Especially in situ measurement of drug structures that interact with proteins in aqueous solutions or cells is a challenge. In this work, mandelic acid (MA) was used as a model molecule to prove that the Raman spectra in the C-H or C-D stretching region can be employed to identify the molecular structure through theoretical and experimental Raman spectra and molecular dynamics simulations methods. Using the experimental and theoretical Raman spectra of MA rotamers, C α -H was determined to be trans (higher than 2950 cm −1 ) and nontrans (below 2950 cm −1 ) from the α-OH group for solid DL-MA (~2961 cm −1 ) and D -MA (~2898 cm −1 ), respectively, which agreed well with the results from X-ray diffraction. Molecular dynamic (MD) simulations and Raman band of the MA aqueous solution revealed that the C α -H group was determined to be nontrans from the α-OH group, the structure of the carboxyl group was cis (~2910 cm −1 ), the carboxyl group was roughly vertical to the C α -benzene bond, and the benzene ring was approximately coplanar with the C α -H bond. Our work also paves that the Raman spectra in the C-D or C-H stretching region could be used as fingerprint regions to study the structure of drugs.

Electrochemical CO 2 reduction is regarded as a promising strategy for the sustainable conversion of greenhouse gas. However, it still remains a significant challenge to manipulate the selectivity and activity. Herein, amorphous and porous Cd modified by sulfur (P–Cd|S) is synthesized by a p-block sulfur dopant. In comparison with unmodified Cd metal, the P–Cd|S architecture exhibits superior activity for selective CO generation, indicating that the sulfur dopant enables a selectivity shift from formic acid to CO. The high selectivity of P–Cd|S is partially ascribed to the local alkalization and suppression of hydrogen evolution as indicated by the finite element analysis. In-depth mechanistic investigations by operando Raman, Infrared, and X-ray photoelectron spectroscopy in combination with theory calculations indicate that the covalently hybridized sp band system with dual collaborative sites (Cd δ + and S δ − ) gives rise to a strong interplay with CO 2 molecules and carbonaceous species, leading to the natural elimination of linear correlation among intermediates binding for d-band metals and the convenient modulation of selectivity toward CO versus HCOOH.

A 3D self-supported integrated electrode, consisting of heteroatomic nitrogen-doped carbon nanotube arrays on carbon cloth with confined ultrafine Co 4 N nanoparticles and a distribution of anchored single-atom Co, is fabricated via a cobalt-catalyzed growth strategy using dicyandiamide as the nitrogen and carbon source and a layered cobalt hydroxide-nitrate salt as the precursor. The abundance of exposed active sites, namely, the Co 4 N nanoparticles, single-atom Co, and heteroatomic N-doped carbon nanotubes, and multiple synergistic effects among these components provide suitable tailoring of the d -band center for facilitating vectorial electron transfer and efficient electrocatalysis. Benefiting from the merits of its structural features and electronic configuration, the prepared electrode exhibits robust performance toward the hydrogen evolution reaction with overpotentials of only 78 and 86 mV at 10 mA cm −2 in acidic and basic electrolytes, respectively. Density functional theory calculations and X-ray photoelectron spectroscopy valence band measurements reveal that the effective tailoring of the d -band center by Co 4 N nanoparticles plays a crucial role in optimizing the hydrogen adsorption free energy to a more thermoneutral value for efficient electrocatalysis.
