Nonoxidative propane dehydrogenation (PDH) is typically constrained by thermodynamic equilibrium and high energy input. Coupling PDH with chemical looping selective hydrogen combustion (CL-SHC) enables in situ H 2 removal to boost propylene production, yet the kinetic factors governing oxygen carrier selectivity remain ambiguous. This paper describes the surface coverage-dependent kinetics of CL-SHC over size-tunable FeVO 4 oxygen carriers (50–200 nm) in propylene-rich streams. Quantitative kinetic analyses reveal that CL-SHC is dominated by surface reaction rather than bulk lattice oxygen diffusion, governed by H 2 /C 3 H 6 competitive adsorption and C−H/H−H bond activation. Specifically, nanosized FeVO 4 ( ca . 50 nm) exhibits favorable H 2 adsorption and surface oxygen exchange, enabling higher SHC selectivity with suppressed propylene over-oxidation. By coupling FeVO 4 with a PtSn PDH catalyst, the tandem system further increases the propylene selectivity to 92% at 500 ° C, representing a 2.7- and 1.5-fold propylene productivity compared to the sole PtSn PDH catalyst and conventional VO x -FeVO 4 tandem systems. This work establishes the structure-kinetics-performance relationship of oxygen carriers for CL-SHC, offering a strategy for rational design of tandem systems toward efficient light alkane upgrading.

Lignocellulosic biomass, which consists primarily of
cellulose,
hemicellulose, and lignin, is a promising renewable feedstock for
producing high-value biobased amines. In this study, an integrated
chemobiocatalytic strategy was developed to synthesize furfurylamine
from corncob using a newly formulated deep eutectic solvent, [Bet][FA][LA],
that provides both catalytic and solubilizing functions. Under optimized
conditions, corncob was efficiently converted into furfural, which
was subsequently aminated by recombinant Escherichia coli BM-AlaDH coexpressing an ω-transaminase
and alanine dehydrogenase. The whole-cell catalyst enabled in situ
regeneration of L -alanine, thereby reducing amine-donor
requirements and improving biocatalytic efficiency. Integration of
[Bet][FA][LA]-mediated chemocatalysis with whole-cell biocatalysis
converted corncob into furfurylamine in [Bet][FA][LA]. The biocatalytic
amination system could convert biomass-derived 5-hydroxymethylfurfural
(320 mM) and vanillin (20 mM) into the corresponding amines in yields
of 95.4% and 91.0%, respectively. This work establishes a sustainable
route for converting lignocellulose-derived aldehydes into value-added
biobased amines and advances the comprehensive valorization of lignocellulosic
biomass.

With the global boom in lithium-ion
battery (LIB) deployment, the
massive production of end-of-life LIBs has become a significant challenge
for resource recycling and environmental risk mitigation. Concurrently,
the advancement of carbon capture is driving an urgent demand for
low-cost, high-performance CO 2 sorbents, among which Li 4 SiO 4 stands out as a promising candidate. A critical
insight is that impurities such as K and Na, which are traditionally
costly to remove during LIB recycling, act as effective dopants to
enhance CO 2 adsorption of Li 4 SiO 4 . To address these dual needs, this work proposes an innovative strategy
for the direct reduction of spent ternary cathode materials via biomass
pyrolysis. By utilizing the synergistic effects of reductive gases
and biochar generated in situ during pyrolysis, Li 2 CO 3 doped with Na and K is recovered and integrated into Li 4 SiO 4 sorbents. Systematic optimization identifies
corn stover (20 wt % addition) as the optimal biomass feedstock, with
pyrolysis-reduction at 650 ° C for 60 min as the ideal condition.
The resulting sorbent exhibits exceptional durability, retaining a
high CO 2 capacity of 0.190 g/g after 80 consecutive adsorption-desorption
cycles. More notably, its production cost is only 19% of that via
conventional routes. This study provides a sustainable pathway for
valorizing spent LIBs while enabling the scalable preparation of CO 2 sorbents, bridging the gap between LIBs’ recycling
and CCUS advancement.

An azithromycin-imprinted electrochemical sensor was developed using hollow nanocages derived from metal-organic frameworks, combined with multi-walled carbon nanotubes. The modification of the molecularly imprinted layer enhanced selective recognition for azithromycin by enabling dual binding modes through covalent (boronate ester bonds) and non-covalent (hydrogen bonding) interactions. The hollow porous structure of the Co 3 O 4 /CNFs (carbon-nitrogen frameworks) nanocages reduced the diffusion distance of electrolytes across the electrode surface, accelerated the redox reaction, enhanced sensing signals, and enhanced sensitivity. Moreover, the combination of Co 3 O 4 /CNFs nanocages and multi-walled carbon nanotubes significantly enhanced the conductivity of the modified electrodes, thus further improving sensitivity. It also provided a larger support area for constructing the imprinted layer, which increased recognition sites. After optimization, the sensor exhibited excellent azithromycin recognition, with a broad linear range (0.2−500 μM) and a low limit of detection (0.12 μM). The sensor showed satisfactory recoveries in real sample analysis (milk = 94.67%−100.99%, urine = 96.89%−107.33%), highlighting its significant potential for monitoring trace levels of azithromycin.

The performance of near-infrared
phosphor-converted light-emitting
diodes (NIR pc-LEDs) is fundamentally limited by the phosphor, which
tends to form defects during high-temperature air synthesis, and these
defects degrade their luminous efficiency and thermal stability. Herein,
we report a Li 2 CO 3 -assisted solid-state strategy
that simultaneously enhances crystallinity and mitigates the undesired
oxidation of Cr 3+ to Cr 4+ in Al 5 BO 9 :Cr 3+ . This is related to the unique decomposition
chemical property of Li 2 CO 3 at high temperatures,
which creates favorable conditions for grain growth and the stabilization
of Cr 3+ . The optimized phosphor exhibits broadband NIR
emission spanning 650–900 nm under 400 nm excitation, with
the internal quantum efficiency significantly increased from 55.4%
to 80.5%. Meanwhile, the luminescence intensity retention at 423 K
rises from 75.3% to 81.9%. A prototype NIR pc-LED fabricated with
a 440 nm chip delivers an output power of 59.4 mW at a drive current
of 100 mA and a photoconversion efficiency of 21%. In cultivation
trials with butterhead lettuce, supplemental lighting from this NIR
pc-LED significantly promotes plant growth, increasing fresh weight
by 28.5% and dry weight by 18.9%. This work provides a practical and
effective flux-assisted approach for preparing high-performance Cr 3+ -doped NIR phosphors under ambient atmosphere.

Spectral information, reflecting the interaction between light and matter across different wavelengths, is essential for identifying material properties and environmental changes. To meet the demand for compact spectral sensors, we constructed a type-I band-aligned MoTe 2 /Te van der Waals (vdW) heterostructure through precise band structure design, where the drain–source voltage ( V ds ) electrostatically tunes interfacial band alignment to complement gate voltage ( V gs ) modulation. By synergistically tuning the V gs and V ds , we achieved a wavelength-dependent photoresponse and constructed a spectral responsivity matrix. Integrated with an attention-guided multilayer perceptron (MLP) algorithm that incorporates the device's responsivity as prior physical information, the device functions as a miniaturized spectrometer, demonstrating narrowband spectral reconstruction with an optimal resolution of 6 nm across a broadband range from 500 to 780 nm at room temperature. The noncentrosymmetric crystal structure of Te also endows the device with the capability of simultaneous polarization discrimination. This work provides a promising approach toward multifunctional on-chip spectrometers capable of simultaneous spectral and polarization analysis.

Repairing infectious tissues, particularly bone and wound infections, poses significant challenges to clinicians due to the lack of effective treatment modalities. Sonodynamic therapy, which utilizes sonosensitizers to generate reactive oxygen species (ROS) under ultrasound (US) energy for antibacterial purposes, still lacks suitable sonosensitizers with good biocompatibility that can simultaneously promote the repair of various infected tissues. In this study, we constructed a novel sonosensitizer composed of hemoglobin derived from nature and zeolitic imidazolate framework (ZIF)-8, which exhibits excellent biocompatibility and activity. This sonosensitizer enables early-stage high-power US to generate substantial ROS for antibacterial effects and late-stage low-power sono-ionic therapy for tissue repair. We employed bone, wound infection, and wound biofilm models to evaluate the therapeutic efficacy in different infected tissues. We utilized microneedles to assemble nanoparticles to match the different disease models, achieving deep biofilm clearance. Furthermore, to investigate the repair mechanisms, we developed a bioadhesive-derived hydrogel loaded with nanoparticles for wound treatment. RNA sequencing revealed that sono-ionic therapy promotes tissue repair through the peroxisome proliferator-activated receptor signaling pathway. Therefore, our platform holds great potential for broad-spectrum treatment of infectious tissue repair.

CTS-SH complexes were developed for rapid flocculation in turbid water. • The complexes significantly enhanced floc growth and structural integrity. • The synergistic system reduced settling time by 68.01% compared with CTS used alone. • Floc size increased by ∼103-fold in CTS/SH synergistic system than in CTS. • Clear defect contours were identified within 2.5–7.5 min in real water samples. Underwater defect detection is markedly hampered by image degradation from light scattering in turbid water, obscuring critical defect features. Herein, the CTS-SH polyelectrolyte complexes were constructed in a two-stage synergistic flocculation strategy for rapid clarification under turbid conditions. CTS was first added to induce pre-flocculation and form initially small flocs. Then, the addition of SH and CTS constructed complexes for further floc growth. Flocculation performance was evaluated in simulated turbid water, while zeta potential, SEM, FTIR, and XPS were employed to elucidate the structural characteristics and underlying mechanisms. Raw water sampled from the SX Dam was used to verify practical applicability. Under simulated turbid-water conditions, the synergistic mode required only 2.45 ± 0.14 min of settling after stirring to reach the target turbidity for clear defect detection, reducing the required time by 64.80% compared with CTS-only system. The CTS-SH complexes formed a three-dimensional leaf network, which offered numerous attachment sites and enhanced sweep capture, increasing floc projected area by approximately 103 times. In raw water tests, defect contours and clear defects could be identified within 2.5 and 7.5 min, respectively. These findings demonstrate a green and effective strategy for rapid clarification and underwater visual detection in turbid environments.

Ru nanoparticles anchored on a heteroatom-doped carbon matrix enriched in pentagonal defects are prepared. • Synergy of pentagonal defects and heteroatoms tunes Ru electronic structure for HzOR and HER. • Ru on S-doped carbon enriched in pentagonal defects delivers superior HER and HzOR activity, surpassing Pt/C. • HzOR-assisted HER system needs only 0.485 V to reach 1 A cm −2 in a flow electrolyzer. Replacing the anodic oxygen evolution reaction with the hydrazine oxidation reaction (HzOR) enables energy-saving hydrogen production but demands efficient bifunctional electrocatalysts. Herein, an electrocatalyst based on ruthenium nanoparticles (Ru NPs) anchored on a uniquely engineered carbon matrix that integrates pentagonal defects and non-metal heteroatoms (Ru/PDXC, X = S, N or P) is designed. Through the synergistic coupling of pentagonal defects and non-metal heteroatoms, the electronic structure of Ru NPs is tailored, thereby enabling modulation of the adsorption energetics of key intermediates for both HzOR and hydrogen evolution reaction (HER). The synthesized Ru/PDSC catalyst delivers outstanding bifunctional activity, requiring a working potential of −70 mV for HzOR and an overpotential of 17 mV for HER to reach a current density of 10 mA cm −2 , outperforming commercial Pt/C. In a two-electrode HzOR-assisted HER system, a low cell voltage of 28 mV is sufficient to achieve a current density of 10 mA cm −2 . Moreover, the flow electrolyzer yields an industrially relevant current density of 1 A cm −2 , requiring a cell voltage of just 0.485 V. This study contributes a fundamental insight for the design and synthesis of advanced bifunctional Ru-based electrocatalysts by engineering the pentagonal defects and non-metal heteroatoms of a carbon matrix.

A multifunctional composite, designated as ZIF-8@LY/ZIF-8@CDs-Eu 3+ , was rationally designed as a fluorescence probe and high-performance photocatalyst for simultaneous detection and degradation of oxytetracycline (OTC). To address the critical challenge of co-encapsulating fluorescein (LY) and Eu 3+ -functionalized carbon dots (CDs-Eu 3+ ) within a single porous particle without functional incompatibility, we proposed a core-shell ZIF-8 architecture, where the etched ZIF-8 core served as the host for LY loading, and the in situ grown ZIF-8 shell was introduced to immobilize CDs-Eu 3+ . The acetic acid etching of the ZIF-8 core created abundant sites to absorb more LY molecules, which further enhanced the OTC removal efficiency. On this basis, a fluorescence “turn-on” ratiometric quantitative detection platform for OTC was established, with a low limit of detection (LOD) of 1.8 nM. Meanwhile, the ZIF-8@LY/ZIF-8@CDs-Eu 3+ composite achieved 99% OTC removal within 300 min under light irradiation, driven by the generated reactive species including superoxide radicals (·O 2 − ), hydroxyl radicals (·OH), and photogenerated holes (h + ). Notably, three parallel degradation pathways of OTC were identified via high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS). This work not only provides an innovative strategy for the design of multifunctional MOF-based composites, but also opens a new avenue for the efficient monitoring and elimination of antibiotic residues in complex environmental matrices.

The development of light aroma-type Baijiu (LAB) industry proposes a growing need for developing rapid and accurate discrimination method for the quality control of LAB. This study innovatively constructed a dual-mode three-channel sensor array based on the gold/platinum nanoparticles (Au@Pt NPs) with surface engineering. In this case, two colorimetric sensor channels based on ascorbic acid/para-aminophenol-chloroauric acid-nanozyme (AA/ pAP-HAuCl₄-Au@Pt NPs) and one fluorescent sensor channel based on nanozyme‑hydrogen peroxide- o -phenylenediamine (Au@Pt NPs-H₂O₂-OPD) were established. Experimental results demonstrate the colorimetric and fluorescence mode can accurately quantify four organic acids and three aldehydes in Baijiu, respectively. Samples including 17 different years and 9 different production processes of basic liquors of LAB, 48 different price gradients of commercial LAB, and adulterated LAB were analyzed. Discrimination with an accuracy exceeding 96% by Linear Discriminant Analysis, Hierarchical Cluster Analysis, and leave-one-out cross-validation was achieved. The dual-mode three-channel sensor array is characterized by simplicity, rapidity and accuracy, providing a new idea for the quality discrimination and market regulation of Baijiu.

Butylated hydroxyanisole (BHA) is a synthetic phenolic antioxidant widely used in edible oils and fat-containing foods. Excessive BHA poses significant risks to human health, thus making rapid and sensitive detection of BHA crucial for health protection. Herein, the Ag 2 CO 3 nanozyme was prepared by the simple precipitation method, which exhibits both laccase-mimic and oxidase-mimic activities. It was found that the oxidase-mimic activity of Ag 2 CO 3 facilitated the conversion of TMB to its blue oxidized form (oxTMB), and subsequent addition of BHA resulted in the formation of a characteristic purple adduct. Additionally, BHA effectively suppressed the laccase-mimic activity of the Ag 2 CO 3 nanozymes. Therefore, a novel colorimetric sensor was constructed using the dual-enzyme-mimic activities as a sensing signal for rapidly detecting BHA in edible oil. The colorimetric sensor achieves limits of detection (LOD) for BHA as low as 1.1 μM in the laccase-mimic channel and 0.08 mM in the oxidase-mimic channel, both of which are substantially lower than the maximum permissible BHA level in edible oils stipulated in Chinese National Food Safety Standard GB 2760. The sensor developed in this work shows great promise for application in the field of edible oil detection.
