In₂O₃ microstructure and surface chemistry was regulated by solvothermal temperature. • 160 °C-In₂O₃-based sensor exhibited a high TEA response of 123.58 at 170 °C. • Abundant chemisorbed oxygen endowed In₂O₃ with superior TEA-sensing ability. • DFT calculations confirmed that oxygen vacancies strengthen the adsorption of TEA on In₂O₃. In this work, a series of In₂O₃ nanomaterials were synthesized via a solvothermal method at 120, 130, 160, and 190°C, and the effects of solvothermal temperature on their crystal structure, surface properties, and triethylamine (TEA) gas-sensing performance were comprehensively investigated. The results showed that the In₂O₃ sample obtained at 160°C delivered the maximum response (123.58) to 50 ppm TEA at the optimal operating temperature of 170°C, together with superior selectivity and long-term stability. Structural characterization revealed that the solvothermal temperature significantly influenced the grain size, surface morphology, and surface adsorbed oxygen content of the samples. Compared with the other samples, the 160 °C-In₂O₃ sample possessed an moderate grain size, a relatively uniform mesoporous structure, and a higher concentration of chemisorbed oxygen species, which facilitated gas diffusion and surface reaction processes. Furthermore, density functional theory (DFT) simulations indicated that oxygen vacancies could enhance the adsorption capability of TEA molecules, thereby promoting the gas-sensing reaction. These findings demonstrated that an appropriate solvothermal temperature could effectively regulate the surface structure and gas adsorption characteristics of In₂O₃, providing valuable guidance for the design of high-performance TEA gas-sensing materials.

Microfluidics enables the fabrication of highly uniform gelatin methacryloyl (GelMA) hydrogel microspheres with broad potential in biomedical applications. However, these GelMA microspheres rely on a single-network architecture generated by free-radical polymerization that is intrinsically defect-rich and structurally heterogeneous, resulting in poor mechanical robustness under shear and compression and thereby limiting practical use. Existing reinforcement strategies require non-homologous additives or multi-step crosslinking schemes that compromise biocompatibility or disrupt microfluidic processing. Here, we address this limitation by reinforcing GelMA microspheres at the microstructural level through partial substitution with o-nitrobenzyl–modified gelatin (GelNB). The underlying NB–vinyl coupling reaction strengthens the hydrogel network without altering the native gelatin formulation, introducing auxiliary reagents, or interfering with droplet-based microfluidic fabrication. The resulting GelNB microspheres exhibit a 3.13-fold increase in compressive strength compared with GelMA counterparts and withstand shear deformation of up to 50% without structural damage. Importantly, they retain inherent cell-adhesive motifs, cytocompatibility, and degradability. They function as degradable microcarriers for 3D cell culture and enable high-fidelity extrusion printing of complex architectures. This strategy broadens the utility of gelatin microspheres for biofabrication, regenerative engineering, and therapeutic delivery.

Developing highly efficient noble-metal-free catalysts for oxygen reduction reaction (ORR) is critical for the widespread commercialization of metal-air batteries. Facet engineering provides an effective strategy to optimize the catalysts’ activity, while the controlling facet orientation in non-precious metals remains challenging. Here we show a substrate-induced growth strategy to synthesize copper nanosheets with specific (200) and (111) facet orientations over nitrogen/oxygen co-doped graphene (N/O-C) via chemical vapor deposition (Cu(200)@N/O-C and Cu(111)@N/O-C), revealing a distinct facet-dependent activity for ORR. It clarifies the substrate oxygen coordination promotes preferential Cu(200) growth under moderate deposition, whereas excess vapor drives thermodynamically favored Cu(111) formation. Theoretical and experimental analyses demonstrate Cu(200) facet in N/O-C optimizes the adsorption energies of ORR intermediates and lowers the reaction barrier for the rate-determining step to outperform the Cu(111), which also exhibits better activity compared to commercial Pt/C. When integrated into zinc-air batteries, Cu(200)@N/O-C delivers a power density of 222.5 mW·cm -2 and stable operation for over 1000 hours, highlighting the potential of facet-engineering on earth-abundant Cu for next-generation energy storage.

Solar-driven photocatalytic CO 2 reduction provides a sustainable pathway for carbon-neutral fuel production, yet its efficiency is fundamentally limited by the chemical inertness of linear CO 2 and inefficient utilization of photogenerated charge carriers. Effective activation of CO 2 requires electron injection into its antibonding π* orbitals, a process that is poorly matched with conventional oxide photocatalysts. Herein, we construct chemically defined Ti-O-Fe interfacial bonds in TiO 2 /Fe 2 O 3 heterojunctions to establish a directional d→π* electron-transfer channel for CO 2 activation. The optimized TiO 2 /Fe 2 O 3 photocatalyst, synthesized via a one-step hydrothermal method, exhibits broadened visible-light absorption and delivers a CO formation rate of 17.56 μmol·g −1 ·h −1 , over three times higher than that of pristine TiO 2 . Spectroscopic analyses and density functional theory calculations reveal that interfacial electron transfer shifts Fe 3d states toward the Fermi level, enabling strong hybridization with the CO 2 π* orbitals and significantly lowering the free-energy barrier for *COOH formation. This bond-mediated electronic coupling not only suppresses charge recombination but also directs photogenerated electrons toward the CO 2 activation pathway. These results demonstrate that interfacial d-band engineering through chemically specific oxide–oxide bonds provide a powerful strategy to program elementary reaction steps in solar-driven CO 2 reduction beyond conventional band-alignment design.

The molecular basis of carbon allocation to proteins and lipids in relation to light-exposure physiology remains poorly understood, particularly in the context of Haematococcus pluvialis growth and metabolism. Therefore, this study aims to elucidate the impact of varying light spectra on H. pluvialis carbon flux, thereby establishing a framework linking light perception with cell division. An integrative methodological approach was developed, combining stable isotope probing (using NaH 13 CO₃) and high-resolution Optical Photothermal Infrared (O-PTIR) microspectroscopy to trace 13 C incorporation into newly synthesized biomolecules under red, blue, and white light. The results showed that red light induced a pronounced spectral red shift (Δν = 8–10 cm −1 at 1665 cm −1 ) associated with amide I vibrations, indicating enhanced protein biosynthesis. Conversely, blue light elicited a significant decline in protein levels from 25.1 ± 0.5% to 21.3 ± 0.4%, whereas lipids rose sharply from 15.2 ± 0.3% to 17.9 ± 0.2%, revealing a “stress-induced” lipid storage phase. O-PTIR visualization showed lipids in membranes and droplets, with proteins uniformly distributed, reflecting their functional compartments. The mid-division stage showed peak biomolecular activity, with protein intensity (602 a.u.) nearly double that of pre-division cells. In conclusion, this study establishes O-PTIR with isotope tracing as a powerful tool for understanding carbon flow and molecular remodeling at the single-cell level, enabling better algal biomass and high-value metabolite production.

Background Trivalent chromium (Cr 3+ ), a relatively environmentally benign and biologically beneficial species of chromium, is widely applied in manufacturing processes as well as in the food and healthcare industries. Exploring a convenient, dependable, and sensitive method for Cr 3+ monitoring becomes practically important for ensuring environmental health and food safety. Results In this study, a o -phosphoethanolamine-functionalized, sheet-like manganese-based nanozyme (OPA@MnT) with excellent oxidase-like activity was designed for sensitive and selective Cr 3+ sensing based on target-induced nanozyme crosslinking. The OPA functional group and nanosheet structure enable specific coordination with Cr 3+ via nitrogen and oxygen donors, triggering aggregation of OPA@MnT and a reduction in active oxygen vacancies, both of which effectively suppress its catalytic activity. Based on this mechanism, a facile colorimetric sensing strategy was established, exhibiting a wide linear detection range (0.25–10 μM), a low detection limit (0.15 μM), and selectivity against potential interfering species. The method was successfully applied to environmental water and dietary supplement samples, showing good agreement with standard ICP-MS measurements. Significance Our work provides a simple, sensitive, and reliable strategy for Cr 3+ monitoring with promising applications in environmental analysis and food safety assessment. Moreover, the elucidated interaction mechanism between metal ions and nanozymes offers valuable insights for the rational design of nanozyme-based sensing platforms for broader analytical applications.

A Bi₄Ti₃O₁₂/BiOCl heterojunction with a coherent interface was constructed via a room-temperature ion-exchange process. • A Bi₄Ti₃O₁₂/BiOCl heterojunction with a coherent interface was constructed via a room-temperature ion-exchange process. • The photocatalyst exhibits excellent performance for the degradation of high-concentration, recalcitrant antibiotics. A strategy is reported for the in-situ fabrication of a Bi₄Ti₃O₁₂/BiOCl heterojunction with shared atomic layer through simple room-temperature ion-exchange on pure Bi₄Ti₃O₁₂. This strategic interfacial engineering, combined with a Type-II band alignment, the Aurivillius-type Bi₄Ti₃O₁₂ and BiOCl share the Bi₂O₂ 2+ layers at the interface, thereby dramatically accelerating the separation and migration of photo-generated carriers and ultimately significantly increasing the yield of photocatalytic reactive species. Consequently, the optimized composite photocatalyst exhibits exceptional performance in the degradation of high-concentration antibiotics. It achieves remarkable degradation efficiencies of 90.8% for sulfamethoxazole (20 ppm) within 120 min, 92% for tetracycline hydrochloride (40 ppm) and 78.6% ciprofloxacin (15 ppm) within just 30 min. Demonstrating superior photocatalytic performance compared to the previously reported analogous photocatalysts in recent years with respect to antibiotic degradation. Furthermore, the degradation efficiency of the as-prepared photocatalyst also demonstrates outstanding cycling stability, with a reduction of only 3.4% after 4 cycles. Therefore, this coherent Bi₄Ti₃O₁₂/BiOCl heterojunction photocatalyst exhibits immense potential for practical applications in environmental remediation.

Ligand-directed inheritance creates asymmetric Cu–N/Cu–O motifs for CO 2 reduction. • Symmetry-breaking preserves highly active Cu δ+ interfaces under dynamic conditions. • Dual-mode *CO adsorption (atop/bridge) effectively bypasses C 2+ scaling laws. • Optimized sites lower C–C coupling barriers while poisoning hydrogen evolution. • Achieved 82.2% C 2+ FE at 0.9 A cm −2 with stable 50 h ampere-scale electrolysis. The electrochemical CO 2 reduction reaction (ECR) to multi-carbon (C 2+ ) chemicals is intrinsically hindered by the rigid scaling relations and geometric homogeneity of pristine copper surfaces, which enforce a singular atop-type *CO intermediate. Herein, we implement a ligand-directed motif inheritance strategy to synthesize nitrogen-doped CuO (N-CuO) nanoparticles, uniquely characterized by asymmetric Cu–N/Cu–O lattice motifs. Under severe cathodic polarization, these robust Cu–N bonds structurally modulate the metallic reconstruction, preserving local non-metal coordination to sustain a highly active, mixed-valence Cu δ+ species. Operando spectroscopic and theoretical analyses reveal that this local structural asymmetry disrupts adsorption homogeneity, explicitly driving the spatial co-adsorption of bridge- and atop-type *CO intermediates. This dual-mode configuration bypasses conventional kinetic bottlenecks to drastically accelerate C–C dimerization. Consequently, the N-CuO catalyst delivers a record-level C 2+ Faradaic efficiency of 82.2% at an industrially relevant current density of 0.9 A cm −2 , exhibiting exceptional structural and catalytic stability over 50 h of continuous flow-cell operation. This work establishes atomic-scale lattice asymmetry as a decisive design principle for stabilizing active Cu δ+ species and steering multi-carbon electrosynthesis at practical reaction rates.

Sulfided NiMo catalysts can effectively hydrogenate oxygen-rich bio-oils into high quality hydrocarbon fuels. However, precisely controlling the cleavage of C−O bonds remains challenging. Here, we synthesized an oil-soluble precursor NiMo 6 -DODA by encapsulating the polyoxometalates (POMs) (NH 4 ) 4 [NiMo 6 O 24 H 6 ] (NiMo 6 ) with surfactants, followed by in-situ construction of an ultra-dispersed monolayer NiMoS catalyst. The “surfactant shell” of the precursor ensured its homogeneous dispersion in the oil phase, while gradually sacrificing and decomposing during the sulfidation to mitigate the aggregation of the MoS 2 nanosheets. Meanwhile, the well-defined “POMs core” established an atomic-level Ni-Mo proximity, ensuring the dominance of the Ni-promoted MoS 2 active phase. This design not only altered the adsorption configuration of esters on the NiMo catalyst but also introduced abundant edge sulfur vacancies to promote oxygen atom adsorption and accelerate C−O bond cleavage. The results showed that NiMo 6 -DODA achieved 100% conversion of methyl palmitate and 100% alkane selectivity under low catalyst loading conditions. Notably, the selectivity for n -hexadecane reached 94.2%, significantly surpassing that obtained with a commercial oil-soluble precursor (69.8%). Furthermore, the catalyst maintained high activity across multiple reaction cycles and in the solvent-free conversion of real bio-oils. This strategy of pre-assembly combined with sacrificial sulfidation provides a simple and effective route for designing hydrodeoxygenation catalysts that enable precise control over ester C−O bond cleavage.

Transition-metal oxides offer a low-cost alternative to precious metals for environmental catalysis, yet CO oxidation under humid and sulfur-laden conditions remains challenging due to rapid poisoning. Herein, we report an atomic dispersion of Ti‑decorated MnO x -Fe 2 O 3 catalyst that achieves high activity and remarkable H 2 O/SO 2 resistance. Atomically dispersed Ti provides electron-accepting 3d states from O 2p orbitals, which redistributes and stabilizes selected O 2p states while modifying their hybridization with neighboring Mn/Fe 3d orbitals. The localized electronic restructuring strengthens CO adsorption and facilitates lattice oxygen activation via a Mars-van Krevelen (MvK)-like mechanism, lowering the apparent activation energy to 64.59 kJ/mol. Simultaneously, Ti-O-Fe interfaces weaken SO 2 adsorption (from −1.96 eV to −0.19 eV) and suppress H 2 O competition, retaining >55% CO conversion under 10 vol% H 2 O and 10 ppm SO 2 , far surpassing the parent oxide (<10%). The orbital tuning strategy enables scalable poison resistant catalysts for industrial emission control, reducing reliance on precious‑metal systems.

The garnet-type Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (LLZTO) is considered a promising solid-state electrolyte (SSE) due to its high ionic conductivity and electrochemical stability. However, the surface of LLZTO easily reacts with H 2 O and CO 2 in the air, forming a passivation layer of Li 2 CO 3 . This reaction further deteriorates the interface between LLZTO and the Li anode, resulting in poor wettability. Consequently, significant gaps form between LLZTO and the Li anode, leading to uneven deposition of Li during the cycling. Li dendrites can grow into these gaps, eventually penetrating the electrolyte and causing a short circuit in the battery. In this study, a surface modification method is investigated, where a thin film of titanium is deposited onto the surface of LLZTO electrolyte tablets using magnetron sputtering. The effects of magnetron sputtering deposition titanium film process parameters—chamber pressure, bias voltage, and temperature—on the electrochemical properties of button cells were investigated. The results indicated that LLZTO electrolyte tablets coated with titanium exhibited low interfacial resistance, high cycle stability, and significant inhibition of Li dendrites under optimized conditions of 1.0 Pa chamber pressure, 100 V bias voltage, and 150 ℃ temperature. Under these conditions, the interface resistance decreased significantly from 1437.9 Ω to 190.19 Ω. Additionally, the Li symmetric cell assembled with the titanium-coated LLZTO electrolyte tablet demonstrated stable cycling for over 1200 h at 25 ℃ under a current density of 0.1 mA·cm −2 .

To enhance the bioaccessibility of vitamin D3 in fortified food systems, hydrodynamic cavitation, ultrasonic cavitation, and an ascorbic acid/hydrogen peroxide system were employed to generate free radicals that mediated the formation of gallic acid-soy protein isolate (GA-SPI) conjugates. The resulting conjugates were used to stabilize emulsions. The emulsion properties and their effects on vitamin D3 delivery were investigated. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) confirmed that covalent conjugation between GA and SPI was promoted by free radical generation in all three treatments. Compared with emulsions prepared with soy protein isolate alone, significant improvements were observed for emulsions stabilized by GA-SPI conjugates, including smaller particle size, higher absolute zeta potential, higher storage modulus, and improved storage stability and antioxidant capacity. These improvements were attributed to GA incorporation and the processing methods. More importantly, when used to encapsulate vitamin D3, bioaccessibility ranged from 53.36 ± 0.57% to 80.06 ± 0.12% for GA-SPI stabilized emulsions prepared by these methods, compared with the untreated group. These findings confirm that emulsion delivery performance can be improved by the three free radical-mediated treatments through promotion of polyphenol-protein conjugation.
