Broccoli microgreens represent a novel type of vegetable characterized by high levels of bioactive compounds. Here, we investigated the effects of light-emitting diode (LED) light quality on the development and nutritional uptake of broccoli microgreens. The plants were exposed to five distinct light treatments: white, single red, and red: blue at 5:1, 5:3, and 5:5 ratios. The soluble sugars, nutrients, and secondary metabolites of broccoli sprout extracts were examined using high-performance liquid chromatography and ultra-high-performance liquid chromatography quadrupole time-of-flight mass spectrometry under various light-quality conditions. In addition, the expression levels of genes encoding important enzymes in the glucosinolates (GLs) biosynthesis pathway were examined using quantitative real-time polymerase chain reaction. Overall, the findings demonstrated that mixed red-blue light, especially the 5:1 red: blue ratio, was beneficial for broccoli microgreens in terms of their hypocotyl length, fresh weight, edible rate, soluble proteins, vitamin C, total phenolics, total flavonoids, and GLs. Our findings provide a foundation and reference point for selecting the most appropriate LED light ratio in microgreens production.

Composites of MIL-101(Fe)/CoFe 2 O 4 were prepared by a simple solvothermal approach and these composites were explored for tetracycline (TC) degradation by using light and persulfate (PS). MIL-101(Fe)/CoFe 2 O 4 catalyst showed superior catalytic performance when combined with photocatalysis and chemical catalysis. Experimental results suggest that the degradation efficiency reached 83% within 40 min. The TC adsorption ability of MIL-101(Fe)/CoFe 2 O 4 was tightly associated with pH, which can be interpreted through isoelectric point. Oxygen-active species, containing singlet oxygen ( 1 O 2 ) or superoxide radicals (O· 2‾), were also generated when there was dissolved oxygen, which could decompose the TC organic contaminant in solution. To be specific, MIL-101(Fe)/CoFe 2 O 4 /PS/Vis catalytic system was capable of eliminating TC through forming h + , 1 O 2 , O· 2‾, hydroxyl radicals (·OH) and sulfate radicals (·SO 4 ‾) species. Moreover, MIL-101(Fe)/CoFe 2 O 4 composite material showed outstanding stability.

Using natural minerals to eliminate harmful Cr(VI) under sustainable sunshine has significant potential. Herein, Palygorskite nanorods were utilized as carriers for the in-situ synthesis of CaIn 2 S 4 photocatalysts through a simple one-pot thermal process, enabling the efficient reduction of Cr(VI). With a Palygorskite to CaIn 2 S 4 mass ratio of 5 %, the conversion rate of Cr(VI) reached 98 % after 60 minutes of visible-light exposure, with a remarkable reaction rate of 0.0633 min −1 . The effective integration of CaIn 2 S 4 with Palygorskite led to a more uniform dispersion of CaIn 2 S 4 , exposing more reactive sites. Moreover, the establishment of a heterojunction between CaIn 2 S 4 and Palygorskite facilitated the transport of photogenerated electrons from CaIn 2 S 4 , enhancing the efficiency of charge separation. These factors contribute to the improved photocatalytic performance. Additionally, the developed composite photocatalysts demonstrated excellent stability under light exposure and could be reused efficiently. Trapping tests on active substances revealed that e − played key roles in the Cr(VI) reduction. This research suggests the potential of using natural minerals to fabricate composite photocatalysts capable of effectively removing pollutants from the environment using solar energy.

Vacuum-deposited perovskite light-emitting diodes (PeLEDs) have demonstrated significant potential for high-color-gamut active-matrix displays. Despite the rapid advance of green PeLEDs, red ones remain a considerable challenge because of the inferior photophysical properties of vacuum-deposited red-light-emitting materials. Here, a rationally designed fluorine-modified phosphine oxide additive was introduced to in-situ passivate vacuum-deposited perovskites. The highly polar 2-F-TPPO incorporated perovskite films demonstrated enhanced photoluminescence quantum yield (PLQY), suppressed defects, and improved crystallinity. When implemented as active layers in PeLEDs, an external quantum efficiency (EQE) of 12.6% with an emission wavelength of 640 nm is achieved, which was 6 times higher compared to the previously reported most efficient vacuum-deposited red PeLEDs (EQE below 2%). Our findings lay the foundations for the further exploration of high-performance vacuum-deposited PeLEDs toward full-color perovskite displays.

The rapid development of near-eye display has put forward higher requirements for the resolution and image quality, while the performance of quantum dots (QDs) is virtually unlimited by pixel size, making them an ideal material for the next generation high-resolution display devices. However, there are still significant challenges in depositing multi-color pixels within the micron range and achieving high performance for the full-color quantum dot light emitting diodes (QLEDs). Herein, a combination of directional transfer printing and Langmuir-Blodgett (LB) technique was utilized to precisely transfer multi-color QDs arrays in the predetermined direction, and the full-color QDs arrays demonstrated fantastic morphology and uniform arrangement. As a result, the full-color QLEDs showed excellent performance with a resolution of 6350 pixels per inch (PPI), a luminance up to 62,947 cd/m 2 and a peak external quantum efficiency (EQE) of 10.03 %. In addition, pixel spacing layers were introduced to further suppress electrical crosstalk and unwanted light emission, and the redundant part of emissive layers enabled QDs to be embedded into pixel spacing layers readily. The resulting full-color QLEDs with independent pixels exhibited a same high resolution of 6350 PPI, with a luminance of 35,427 cd/m 2 and a peak EQE of 8.55 %. Our work represents the best performance of full-color QLEDs with both high efficiency and high resolution, which demonstrates great potential in the application of future near-eye displays.

In this paper, the rare earth europium complex Eu(FTFA) 3 TPPO 2 (EuFT) was synthesized by using europium as the central ion, 4-trifluoro-1-(2-furanyl)-1,3-butanedione (FTFA) as the first ligand, and triphenylphosphine oxide (TPPO) as the second ligand. The structure was characterized by Fourier transform infrared spectroscopy (FTIR), and the photoluminescence process was investigated by UV and fluorescence spectra. The luminescent film was prepared by adding EuFT and the compatibilizer POE- g -PHEMA into the POE matrix, which can convert the UV light to the red light, and improve the photovoltaic conversion efficiency while reducing the effect of UV aging on the cell. Experimental results show that the complex can absorb UV light (200–400 nm) and emit red light (612 nm), the luminescent film also maintains good luminescence performance. The peel strength of POE/POE- g -PHEMA/EuFT film achieves 23.9 N cm −1 ，while that of POE film is 12.8 N cm −1 . The silicon cell prepared by POE/POE- g -PHEMA/EuFT film also showed higher EQE in UV region, and its current density–voltage (J–V) curve revealed that J sc increased from 33.05 to 34.25 mA/cm 2 , the conversion efficiency increased from 12.99% to 13.39%, and the relative efficiency increased by 3.08%. The rare earth europium complex effectively improved the photoelectric conversion efficiency of solar cells.

This study significantly enhances the photo(electro)catalytic capabilities of CuAlO 2 , a wide bandgap semiconductor, through targeted defect engineering. By employing a tailored solid-state reaction under a mixed oxygen-argon atmosphere, an intrinsic defect complex of [O i +Cu Al ] into has been successfully integrated into CuAlO 2 , thereby expanding its light absorption to the visible spectrum. The optimized CuAlO 2 sample, containing the [O i +Cu Al ] complex, demonstrates a remarkable 2.13-fold increase in photocatalytic degradation of tetracycline hydrochloride under visible-light irradiation. The maximum incident photon-to-current conversion efficiency value is elevated from 0 to 3.27 %, and the photocatalytic water splitting hydrogen production rate is increased by 10.78-fold. Density functional theory calculations, in conjunction with experimental data, elucidate the role of the [O i +Cu Al ] complex in facilitating visible-light absorption and improving the separation of photogenerated electron-hole pairs. Under simulated sunlight, the modified CuAlO 2 sample exhibits a substantial 2.26-fold enhancement in photocatalytic degradation of tetracycline hydrochloride, a photocurrent density increase from 0.80 to 8.20 µA·cm −2 , and a 1.13-fold increase in photocatalytic hydrogen production rate compared to defect-free CuAlO 2 . This research underscores the potential of strategic defect engineering to enhance visible-light-driven photo(electro)catalysis in wide bandgap semiconductors.

Energy-saving materials have vast application prospects in the field of construction. The development of energy-efficient and smart glass is crucial for reducing building energy consumption and improvin g human living environment. In this study, We developed a novel composite material with a Cs 0.33 WO 3 @TiO 2 core-shell structure, where TiO 2 is precisely deposited on the surface of Cs 0.33 WO 3 . The incorporation of TiO 2 into Cs 0.33 WO 3 enhances visible light transmittance and significantly improves near-infrared (NIR) absorption by forming a protective core-shell structure. This structure shields Cs 0.33 WO 3 from environmental degradation while also promoting efficient charge transfer, thereby modifying its electronic properties and further boosting NIR absorption. Additionally, TiO 2 strengthens the localized surface plasmon resonance (LSPR) of Cs 0.33 WO 3 , amplifying its overall NIR absorption capacity. Cs 0.33 WO 3 attracts electrons from TiO 2 , allowing more W 6+ to be reduced to W 5+ and enhancing the transparent heat insulation performance by a factor of 4.5. Meanwhile, the core-shell heterojunction of S-scheme narrows the band gap of TiO 2 and accelerates the charge separation and transfer, retaining more active photogenerated carriers to participate in the surface redox reaction and exhibiting a 11-fold increase in the photocatalytic rate. Furthermore, a superhydrophilicity property of the composite is achieved at a contact angle of 4.5°, demonstrating strong potential for self-cleaning application. The design and fabrication of this composite material with multifaceted functions offer valuable insights for practical applications in energy-saving coating films, contributing to low-carbon development.

Photocatalysis is a promising method for methylene blue (MB) degradation due to its effectiveness and environmental compatibility. Among the photocatalysts, titanium dioxide (TiO2) has been widely used for MB degradation due to its exceptional photocatalytic activity. However, the wide bandgap limits the degradation efficiency of TiO2under visible light. Here, an interstitial nitrogen-doped TiO2(5%NT/TiO2) used thiourea as the N source was fabricated for visible light-derived MB degradation. The 5%NT/TiO2exhibited an extended absorption range of visible light. Moreover, photoelectrochemical measurements showed an improvement in the photocurrent response and charge transfer behavior on N/TiO2. Thus, 5%NT/TiO2had enhanced photocatalytic activity compared with pristine TiO2and substitutive N-doped TiO2(5%NAB/TiO2). The accelerated photocatalytic MB degradation process on N/TiO2could be mainly attributed to the interstitial N doping, which caused the appearance of new energy states and extended optical properties. Through comparing the impact of interstitial and substitutive in TiO2activity, our work proposes a suitable form of element doping to enhance the optical properties and photocatalytic activity of TiO2and even other semiconductors, providing guidance for future work.

The isotopic fractionation of organic compounds during evaporation is one of the most critical issues in the field of stable isotopes. The hydrogen (H) isotopic compositions of light hydrocarbons (LHs) in oil have gained increasing interest in the research of oil genesis in recent years. However, compared to carbon (C) isotopes, our understanding of H isotopic fractionation patterns and influences for various types of LHs during evaporation is limited. In this study, we performed evaporation experiments at a constant temperature on LHs in three systems: single compound, alkane mixture, and light oil. We assessed the contents and H isotopic compositions of individual LHs in the residual liquid phase. The degree of H isotopic fractionation and influencing factors are studied combined with C isotopes. The H isotopic fractionation of LHs exhibits “inverse isotope fractionation” characteristics (a depletion in D in the residual LHs) with progressive evaporation, which is opposite to the C isotopic fractionation. The degree of isotopic fractionation is influenced by the evaporation system, the compounds’ molecular weight, and their structure. (1) The isotopic fractionation degree of H and C decreases in the following order: light oil > alkane mixture > single compound system. This difference may be related to the unsaturation level of the evaporative system and the evaporation matrix. (2) For LHs with the similar structure in the same evaporation system, the degree of H isotopic fractionation increases with increasing molecular weight due to the buffering effect of the sample pool, while the magnitude of C isotopic fractionation decreases. (3) For LHs with the same C number, methylcyclohexane (MCH) has a lower evaporation rate and less isotopic fractionation than the other C 7 compounds like 3-methylhexane (3-MH), n -heptane ( n C 7 ), and toluene (Tol). The distinctive fractionation characteristics of H isotopes make them very useful in geological applications. Combining H and C isotopic compositions of the same compound with the commonly used molecular ratios of LHs (e.g., n C 7 /MCH, Tol/ n C 7 ) enables full differentiation of three critical processes controlling oil formation: evaporation, thermal maturation, and biodegradation. Furthermore, the differences in H isotopic compositions between C 7 LHs (3-MH, n C 7 , and Tol) may be changed by evaporation, but the variation range is much smaller than that caused by source differences. Therefore, combining H and C isotopes may have great potential for oil source characterizations.

Capillary force self-assembly (CFSA) technology unfolds great potential in the fabrication of functional micro/nanostructures. To date, most self-assembly methods focus on monolithic microstructure manipulation yet it remains a challenge to achieve precise localized control over the CFSA process of micro/nanostructures. Herein, a light-regulated CFSA is proposed to realize the localized precise control of microstructures, leveraging on the synergistic effect of photothermally-responsive hydrogel and self-assembly technique. The micropillars with asymmetric cross-linking densities can readily prepare by applying a rationally designed laser and laser-exposing dosage, thereby realizing the on-demand steering of their bending directions. Significantly, owing to the giant capillary force deriving from the evaporating water, above micropillars can successfully assemble into highly-ordered chiral structures. Simulation coupling with fundamental hydrodynamics enables to shed light on the light steering principle over pillar's actuations. Last, on the basis of vortical dichroism spectra analysis, the chiral characteristics of light-regulated self-assembly including the chiral as well as the achiral self-assembled microstructures are successfully deployed. This strategy provides an avenue for fabricating the localized controllable self-assembly at the microscale and will bloom the field over metamaterials, microsensors, chiral optics, and so on.

In this paper, a series of corncob carbon modified g-C 3 N 4 composite catalyst with excellent visible light response properties was synthesized via a simple one-pot co-solvothermal method. The catalysts displayed enhanced adsorption performance and photocatalytic activity of 98.89 % and 99.08 % on Rhodamine B (RhB) and methyl orange (MO) removal efficiency under visible light irradiation, respectively. The superoxide radical and hydroxyl radical were the dominant reactive oxygen species involved in the photocatalysis reaction. The significantly enhanced adsorption and photocatalytic performance of the catalysts was ascribed to the porous structure and the strong interactions between g-C 3 N 4 and corncob carbon. After six cycles of experiments, the catalysts still exhibit stable and high performance for the removal efficiency of RhB and MO. Based on the analytical results, a possible mechanism of photocatalytic degradation was proposed in detail. The corncob carbon modified g-C 3 N 4 composites can be regarded as a potential catalyst in the application of the dye wastewater treatment.
