This study aimed to elucidate how garlic-derived volatile compounds, particularly sulfur-containing odorants, dynamically migrate and accumulate within the complex matrix of light soy sauce over time. The volatile profiles at different migration intervals were analyzed using an electronic nose (E-nose) and gas chromatography-mass spectrometry (GC-MS). Systematic evaluations of differences in odor profiles and dynamic changes in volatile compounds were conducted through odor activity value (OAV) analysis and orthogonal partial least squares discriminant analysis (OPLS-DA). E-nose analysis demonstrated that prolonged migration times facilitated the transfer of sulfur-containing volatile compounds from garlic into light soy sauce, significantly increasing the response values of sensors TA/2 and T40/1 ( p < 0.05), thereby altering the aroma characteristics of the soy sauce. GC-MS analysis revealed that as migration time increased, the concentration of sulfur-containing volatile compounds(0 → 140000 μg/L) from garlic in light soy sauce significantly rose ( p < 0.05). OAV analysis suggested that the aroma profile of garlic-flavored soy sauce resulted from the combined contributions of sulfur-containing compounds and the major volatile components of soy sauce. VIP analysis based on OAV and OPLS-DA identified 18 key substances, including methyl valerate and isobutylbenzene, as the primary contributors to the differences among samples at various migration times. A key finding was the linear positive correlation observed between the migration quantity of garlic odor compounds migrating into soy sauce and migration time. This study enhances our understanding of the migration mechanisms of garlic flavor substances in light soy sauce.

The synthesized FeVO 4 /MXene composite photocatalysts demonstrated exceptional photocatalytic activity in activating PMS, removing 100% of 2,4,6-trichlorophenol (2,4,6-TCP) within 20 minutes. The incorporation of MXene effectively reduced photogenerated electron-hole pairs recombination in FeVO₄, enhancing charge transfer efficiency. Mechanistic studies revealed that synthesized FeVO 4 /MXene generated more •OH and ¹O₂ through the reaction between h⁺ and PMS. Furthermore, the photogenerated electrons (e⁻) facilitated Fe redox cycling within the system. The FeVO 4 /MXene/PMS/Vis system not only achieved efficient separation of photogenerated charge carriers but also reduced the required PMS dosage by 75%. Remarkably, the FeVO₄/MXene composite maintained its structural integrity after five consecutive cycles while retaining 98% of its initial degradation efficiency for 2,4,6-TCP, demonstrating excellent durability and promising application potential.

Zn-doped MnCO3/carbon sphere (Zn-doped MnCO3/CS) composites were synthesized using a simple hydrothermal procedure. Among various samples (ZM-50, ZM-05, and ZMC-0), the ternary Zn-doped MnCO3/CS (ZMC-2) catalyst demonstrated excellent visible light-induced photocatalytic activity. This improvement comes from the Zn addition and the conductive CS, which facilitate electron movement and charge transport. The catalyst exhibited efficient degradation of methylene blue (MB) over a wide pH range, achieving a removal efficiency of 99.6% under visible light. Radical trapping experiments suggested that •OH and •O2−played essential roles in the mechanism of organic pollutant degradation. Moreover, the catalyst maintained good degradation performance after five cycles. This study offers valuable perspectives into the fabrication of carbon-based composites with promising photocatalytic activity.

Developing magnetic adsorbents with superior adsorption capability has always been a massive challenge. Herein, an in-situ growth strategy was implemented to build polydopamine-encapsulated lightweight hollow magnetic microspheres and used to achieve selective recovery of gold from e-waste. The fabricated magnetic-dielectric microspheres, including hollow magnetic polydopamine microspheres (HMPM) and hollow magnetic polydopamine microspheres modified by allyl thiourea (HMPM&A), exhibited excellent gold adsorption capacities of 1205 mg g −1 and 1766 mg g −1 , respectively at 298 K. The adsorption capacity was amazingly upsurged up to 1850 mg g −1 and 2715 mg g −1 under ultraviolet light, respectively, which is relatively enhanced compared to other reported magnetic adsorbents. The XPS survey and DFT calculations confirmed that Au(III) ions adsorption principally attributed to electrostatic interaction of N sites under acidic mediums and chelating interaction between Au(III) and S,N chelating site of thiourea groups, followed by subsequent reduction of Au(III) into to Au(0) with thiourea and dopamine units. The developed magnetic adsorbent showed impressive chemical stability for Au(III) adsorption up to eight consecutive adsorption-desorption cycles without any noticeable change in adsorption performance. The recovery rate of HMPM&A for Au(III) ions from actual samples was better up to 86.7 %. This work will broaden the construction strategy of magnetic adsorbents and promote the application of magnetic materials as an efficient functional material.

Organic–inorganic metal halides have recently garnered significant interest owing to their excellent photoluminescence performance and high stability. Therefore, a synthetic procedure was designed here to obtain (PPZ)ZnBr 4 (PPZ = 1-phenylpiperazine) nanocrystals (NCs) incorporating Pb 2+ and Sn 2+ ions, obtaining blue and orange light emitters, respectively. Photoluminescence quantum yields of blue and orange emissions were up to 43.2% and 29.9%, respectively, under 365-nm excitation. The prepared NCs also demonstrated long-term stability and humidity resistance. This study not only provided a deep comprehension of low-dimensional perovskites, but also established an avenue for the strategic design of high-performance light-emitting perovskites.

Face masks play a pivotal role in preventing infection transmission. However, the capture of infection-sourced particles in face masks poses challenges related to reuse, necessitating proper disposal. We developed a self-sterilizable polypropylene-based membrane for face masks to address challenges associated with infection transmission prevention. The membrane, created using 3D printing, underwent functionalization with zinc oxide (ZnO) and polydopamine (PDA)-TEMPO to achieve broad-spectrum light absorption and facilitate self-sterilization through photocatalytic and photothermal effects upon light exposure. The hydrophobic surface (water contact angle: 133 ± 2°) minimized moisture accumulation, and the membrane exhibited robust mechanical properties, including shear strength (1.25 ± 0.5 kPa) and peel resistance strength (112.8 ± 11.2 kPa). The evaluation demonstrated stability in airflow (0–500 cm 3 /s) and excellent aerosol filtration efficiency (94.8 ± 0.6 %) for particles (PM 0.3, PM 2.5, PM 10), comparable to commercial masks. The membrane showed antibacterial efficacy over five uses in a simulated respiratory environment. Safety assessments confirmed biocompatibility through cytocompatibility and skin irritation assays. In conclusion, this membrane offers efficient filtration and photo-triggered sterilization, presenting a promising solution for next-generation face masks to address concerns related to reuse, disposal, and infection control.

Confined catalysis, where a chemical reaction is accommodated within a nanoscale host, provides an effective approach to control the pathways and outcomes of catalytic transformations. However, the confinement effect is typically limited to a fixed rate and/or selectivity once the nanohost is chosen. Herein, we developed a photoresponsive metal–organic framework (MOF) as a “smart” nanohost to realize ultraviolet (UV) light-enhanced confined catalysis of Knoevenagel condensation. Photoresponsive MOF of Zn-ADA was thus prepared by solvothermal strategy where azobenzene-4,4′-dicarboxylic acid (ADA) was used as the photoactive linker to coordinate with zinc nitrate. Characterization results suggested that UV light could decrease the pore size of Zn-ADA due to suppressed bending of the azobenzene-containing ADA linker in Zn-ADA. It enforced the proximity between substrates and catalytic groups within the confined space, and thus enhanced the confinement effect on Knoevenagel condensation. The UV light-enhanced confined catalysis enabled the translation of light stimulus into chemical signal, which may open up new control on the basis of the specific reaction field.

A phenomenon known as plasmon resonance constitutes a unique optical effect that can induce an enhancement in localized electromagnetic fields, resulting in a substantial increase in the electromagnetic field intensity surrounding metallic nanostructures. In this work, the coupling effect of excitation of surface plasmon polaritons and local surface plasmons in nanoparticles is deeply studied under the background of nanoparticles/one-dimension grating composite structures through grating matching. By employing finite-difference time-domain simulations as our methodological approach, we discern gratings with a periodicity of 1.5 μm support surface plasmon bound states between the gratings. Furthermore, the modulation of SPs along the vertical sidewalls of the grating due to standing wave effects exhibits oscillatory behavior with varying grating heights. Experimental results obtained from the nanoparticle/grating composite SERS substrate validate theoretical predictions, demonstrating higher enhanced Raman signals at 633 nm compared to 532 nm. Remarkably, this structure exhibits good performance, with R6G detection sensitivity down to concentrations as low as 10−10 M and mapping achieving a relative standard deviation of 7.79%, underscoring its uniformity and capability of electromagnetic field enhancement.

Production of H 2 O 2 via semiconductor photocatalysis has received an increasing attention. Herein the effects of cations in perchlorate form and anions in sodium form are examined. Experiment was conducted with Au/WO 3 under visible light in presence of methanol. The production of H 2 O 2 was greatly promoted by A (Ni 2+ , PO 4 3− , CO 3 2− , and F − ), slightly increased by B (SO 4 2− , NO 3 − , Cl − , and ClO 4 − ), greatly inhibited by C (Cu 2+ , and Fe 3+ ), and slightly decreased by Co 2+ . Moreover, the effect of Ni 2+ was weakening by F − , and vice versa. Analysis showed that Ni 2+ was oxidized into Ni 3+ , reactive to methanol, not to water. On Au/WO 3 electrode, anions A inhibited O 2 reduction, and promoted methanol photo-oxidation, while all anions had little influence on the pathway of O 2 reduction. A plausible mechanism is proposed, involving the hole oxidation of anions (not F − ), followed by methanol oxidation. This work highlights the importance of inorganic ions to the selective reduction of O 2 .

Summary Light and temperature in plants are perceived by a common receptor, phytochrome B (phyB). How phyB distinguishes these signals remains elusive. Here, we report that phyB spontaneously undergoes phase separation to assemble liquid-like droplets. This capacity is driven by its C terminus through self-association, whereas the intrinsically disordered N-terminal extension (NTE) functions as a biophysical modulator of phase separation. Light exposure triggers a conformational change to subsequently alter phyB condensate assembly, while temperature sensation is directly mediated by the NTE to modulate the phase behavior of phyB droplets. Multiple signaling components are selectively incorporated into phyB droplets to form concentrated microreactors, allowing switch-like control of phyB signaling activity through phase transitions. Therefore, light and temperature cues are separately read out by phyB via allosteric changes and spontaneous phase separation, respectively. We provide a conceptual framework showing how the distinct but highly correlated physical signals are interpreted and sorted by one receptor.

Near-infrared (NIR) emission underpins biomedical imaging, night vision, and optical communication. Yb 3+ -doped CsPbCl 3 have demonstrated ultrahigh photoluminescence quantum yields via quantum cutting, primarily enabled by a singular defect-assisted energy transfer pathway arising from the substitution of Pb 2+ by Yb 3+ . However, whether additional pathways exist to facilitate visible (VIS)-to-NIR conversion, thereby further enhancing the performance of NIR-emissive devices, remains an open and compelling question. Here, strategic engineering of localized bound excitons (BEs) is proposed in the thermally evaporated CsPbCl 3 :Yb system. Assisted BEs significantly promote energy transfer from CsPbCl 3 matrix to Yb dopants, unveiling a previously unknown excitonic energy transfer channel. Atomic-scale characterization combined with first-principles calculations uncovers a BE-driven excitonic transfer mechanism, specifically implicating Cs-vacancy-induced defects in mediating exciton behavior. These insights lead to the fabrication of high-performance NIR-LEDs with an 8.9% external quantum efficiency and 410 mW·Sr −1 ·m −2 radiance, marking a breakthrough in thermally evaporated NIR (>950 nm) light-emitting diodes.
