Cumene,
produced via the alkylation of benzene with propene, is
a crucial intermediate for phenol and acetone. The catalytic performance
depends on framework architecture, crystal size, and the acid properties
of zeolites. Co-Al-LDO-β was synthesized by anchoring nanosized
β zeolite onto cobalt-aluminum layered double hydroxide (Co-Al-LDH)
via an in situ strategy, where Co-Al-LDH served as both an aluminum
source and support. The uniform dispersion of β zeolites on
the LDH allowed for tuning of the polymorph A/B ratio. The influence
of polymorph distribution on pore architecture and acid site distribution
was investigated by XRD, HRTEM, NMR, and pyridine-FTIR. The results
show that polymorph B enriches framework aluminum at T2 sites, forming
accessible Brønsted acid sites. Polymorph A induces aluminum
migration to constrained T7 and T5+T6 sites and extraframework aluminum,
increasing Lewis acidity. The B-type dominant β zeolite has
a favorable pore structure and acid site distribution, leading to
superior catalytic performance in benzene–propene alkylation.

β-Carotene is widely utilized in food systems due to its biological activities, but exhibits poor chemical stability and low bioavailability. This study utilized wholeAuricularia polytricha(Mont.) Sacc. powder as a direct emulsifier to establish a natural emulsion-based delivery system designed to enhance the stability ofβ-carotene. Under optimal conditions, using 7%Auricularia polytricha(Mont.) Sacc. powder (120 μm) and 1% oil phase fraction, microscopic analysis revealed that emulsion droplets were small and uniformly distributed, resulting in excellent long-term stability. After UV irradiation, the degradation rate ofβ-carotene in the emulsion was significantly lower than that ofβ-carotene directly dispersed in the oil phase.In vitrosimulated digestion indicated thatβ-carotene retention in the intestinal phase reached 9.2% in the emulsion system, 1.2 ± 0.23% higher than in the conventional oil-dissolved system. This strategy offers a practical approach for the high-value utilization of this fungal resource, streamlining industrial processes and reducing production costs.

Selective ring-opening (SRO) of bulky polycyclic cycloalkanes is a crucial process for producing high-quality fuels; however, its decisive catalytic descriptors remain poorly understood. Herein, the roles of different acid distributions on the SRO of perhydrophenanthrene were investigated by preparing a series of bifunctional Ir/β catalysts with different external Brønsted acid sites (BAS) densities. The results showed that the SRO of perhydrophenanthrene was governed by the density of externally accessible BAS, rather than by the total acidity or internal acid sites. The Ir/ExB catalyst enriched in external BAS exhibits markedly enhanced SRO activity and selectivity, whereas those with insufficient external BAS show negligible ring-opening performance. The SRO product yield exhibits a clear linear increase with the increase in external BAS density. These findings identify externally accessible BAS as a decisive descriptor for bulky polycyclic alkane SRO and provide guidance for the rational design of bifunctional Ir/β catalysts.

Currently, the efficient co-encapsulation of different bioactives remains a challenge. To enhance the activity and stability of encapsulation systems and reduce energy consumption, this study employed pulsed ultrasonic treatment (PUT) to prepare a nanoliposome system and evaluated its effects by combining molecular simulation and experiments. Results showed that treatment with a 15/5 s pulse ratio for 9 min significantly improved the activity (38.25%) and co-encapsulation efficiency of β-carotene (βC) and maize peptide (MP) (66.75% and 60.38%), while reducing energy consumption by 25%. Molecular insights revealed that PUT induced structural relaxation of MP, thereby enhancing its binding with βC and liposomes (by 11.73%) and consequently improving co-encapsulation. This method also significantly enhanced the stability under high temperature, oxidation, and light. This research elucidated the molecular mechanism by which PUT promoted encapsulation, offering a promising approach for the efficient and low-energy co-encapsulation of bioactives, while also contributing to enhanced activity and stability.

A bifunctional evaporator for sola evaporation and photocatalysis was developed. • The 3D hydrogel shows broad-spectrum solar absorption and high energy efficiency. • The Z-scheme heterojunction boosts charge separation and phenol degradation. • A detailed degradation mechanism and reaction pathway of phenol are proposed. Solar interfacial evaporation (SIE) has attracted increasing attention in recent years due to its environmental friendliness, high efficiency, and low-carbon-emission characteristics. However, volatile organic compounds (VOCs) are often not effectively removed during the evaporation process, which can lead to secondary contamination of the collected condensate. Integrating SIE with photocatalysis for seawater desalination has therefore emerged as an effective strategy to mitigate the accumulation of VOCs in the condensate during seawater treatment. In this study, manganese (IV) oxide nanomaterials were coated with silver bromide to construct an AgBr/β-MnO 2 heterojunction that suppresses the fast charge annihilation of photoinduced electron–hole pairs and enhances photocatalytic efficiency. The resulting composite was further incorporated into a photothermal hydrogel (AgBr/β-MnO 2 -PH) matrix with excellent photothermal evaporation properties, forming a three-dimensional (3D) photocatalytic evaporation system capable of significantly improving the removal efficiency of VOCs during photothermal evaporation. Under standard solar irradiation (1 sun, 1 kW m −2 ), the porous acrylamide-based hydrogel evaporator achieved an evaporation rate of 3.47 kg m −2 h −1 and a photothermal transformation efficiency of 93.98%. In-situ irradiated XPS reveals light-induced electron enrichment on AgBr accompanied by electron depletion on β-MnO 2 , providing experimental support for a direct Z -scheme interfacial charge-transfer pathway that promotes carrier separation and reactive oxygen species (ROS)-mediated photocatalysis. Consequently, the AgBr/β-MnO 2 -PH system exhibits a removal efficiency exceeding 99% when treating phenol-containing wastewater. Overall, this work demonstrates an effective strategy for coupling SIE with photocatalytic degradation of VOCs. The developed AgBr/β-MnO 2 -PH provides a promising approach for producing freshwater from VOC-contaminated sources and offers new insights into the application of solar energy in seawater desalination and wastewater purification.

β-Ga 2 O 3 material with wide band gap and high radiation resistance, is potential in the application of X-ray radiation detections, and UV photoelectric detectors. The detector properties, such as sensitivity, response speed and stability, strong depend on the crystal quality of β-Ga 2 O 3 material. In this paper, β-Ga 2 O 3 thin films composed of crystalline grains were fabricated on sapphire substrates using the chemical vapor deposition technique. The thin films underwent annealing treatment in oxygen and a mixed ambient (5% H 2 +95% Ar), respectively. The effects of annealing on the structural, surface morphological and optical properties were investigated. X-ray photoelectron spectroscopy indicated the oxygen vacancy concentration decreased after annealing treatment. Overall, the β-Ga 2 O 3 thin films annealed in the hydrogen ambient displayed the best recrystallization characteristics, the process was discussed. The role of hydrogen quietly differed to oxygen during the annealing treatment, hydrogen promoted the decomposition of β-Ga 2 O 3 grains, followed by regrowth of β-Ga 2 O 3 with a preferred orientation, where decomposition and regrowth occurred competitively. The crystalline grains presented a gradual increase in size from as-grown to O 2 -annealed and H 2 -annealed β-Ga 2 O 3 thin films. Meanwhile, the grains annealed in hydrogen displayed a distinct alignment. The epitaxial relationships between the β-Ga 2 O 3 thin films and the sapphire substrate were investigated. Photoluminescence and absorption spectra were measured, the emission peaks fitted by Gaussian functions, and the deduced optical bandgap indicated the influence of the annealing treatment on the recrystallization of β-Ga 2 O 3 .

The promotion of covalent grafting of seven structurally distinct polyphenols to β-Lactoglobulin (β-LG) via cold plasma (CP) treatment, and their influence on functionalities and antigenicity of β-LG were systematically investigated. Results indicated that covalent β-LG-polyphenol conjugates were generated after undergoing 45 s of CP treatment, with the highest (135.49 ± 1.87 μmol/g) and lowest (2.56 ± 1.43 μmol/g) polyphenol content in β-LG-(−)-epigallocatechin gallate (β-LG-EGCG) and β-LG-syringic acid (β-LG-SA) conjugates, respectively. This result clearly demonstrated that the binding capacity is directly related to the number of phenolic hydroxyl (-OH) groups in polyphenols. Multispectral analysis revealed that the β-LG's spherical conformation unfolded upon covalent grafting with polyphenols. Further analysis of functionalities and antigenicity revealed that improvement in functionalities and reduction in antigenicity of β-LG was positively correlated with the grafted polyphenol content. The β-LG conjugates modified with EGCG displayed a maximum decrease in antigenicity (58.40 ± 1.03 %), a nearly seven-fold increase in DPPH, and a five-fold increase in ABTS free radical-scavenging capabilities when compared to native β-LG. According to LC-MS/MS and immunoblot analysis, the primary cause of the decrease in antigenicity was the disruption of the linear IgE epitope in β-LG as a result of conjugated EGCG's masking and steric hindrance impact. These findings demonstrate that CP is a reliable method for promoting covalent conjugation between polyphenols and proteins. Moreover, the binding affinity was found to be positively correlated with the number of -OH groups present in the polyphenol, which is a key structural determinant for enhancing functional properties and for reducing the antigenicity of the resulting protein-polyphenol complexes.

Rare-earth-doped β-Ca 3 (PO 4 ) 2 -type derivatives are a research hotspot in optoelectronics materials, yet achieving eye-friendly comfortable emission in such multication lattice systems remains a challenge. Herein, a novel orange-emitting phosphor Sr 7 LuNaMg 1.5 (PO 4 ) 7 :Eu 2+ was designed based on the crystal structure of Sr 9 Fe 1.5 (PO 4 ) 7 (ICSD No. 93870), whose structure is topologically similar to β-Ca 3 (PO 4 ) 2 . The title phosphor exhibits ultra-broadband emission centered at 599 nm (full-width at half-maximum = 197 nm) under 395 nm n-UV excitation. Structural characterization coupled with spectroscopic studies demonstrates the coexistence of multiple luminescent centers in Sr 7 LuNaMg 1.5 (PO 4 ) 7 :Eu 2+ . A progressive redshift in the emission color coordinates was observed with increasing Eu 2+ doping concentrations, attributable to selective cation occupancy and crystal field effects. The concentration-dependent quenching mechanism was elucidated through comprehensive analysis based on Dexter's theory. Characterization of quantum efficiency, thermal stability and packing density validated the suitability of Sr 7 LuNaMg 1.5 (PO 4 ) 7 :Eu 2+ phosphor for high-performance white light-emitting diodes, demonstrating it as a competitive luminescent material for advanced lighting technologies.

In this study, a PEDOT:PSS@graphene composite structure was engineered by incorporating graphene into PEDOT:PSS, thereby significantly enhancing its electrical conductivity. This composite layer was subsequently integrated with high-crystallinity β-Ga2O3 microwires (MWs), synthesized via chemical vapor deposition (CVD), to fabricate a self-powered deep-ultraviolet (DUV) photodetector. The device exhibited an ultra-low dark current of only 0.13 pA under a bias of 10 V, highlighting its superior noise suppression capability. More importantly, under 245 nm illumination at a bias of 0 V, the photodetector demonstrated a remarkable responsivity of 65 mA W−1, which represents enhancements by factors of 48 and 4 compared with PEDOT:PSS/β-Ga2O3 MW and graphene/β-Ga2O3 MW heterostructures, respectively. In addition, the device achieved a high specific detectivity of ∼1012 Jones. These outstanding photoresponse characteristics can be primarily attributed to the incorporation of graphene, which improves the conductivity of the PEDOT:PSS layer while simultaneously strengthening the built-in electric field at the heterojunction interface, thereby facilitating more efficient separation and transport of photogenerated carriers. Overall, this work demonstrates a promising strategy for designing organic–inorganic hybrid heterostructures and offers new insights into the development of high-performance, self-driven solar-blind photodetectors.

Traditional β-eucryptite (LiAlSiO4) is renowned for its unique characteristics of low thermal expansion and high temperature thermal stability, making it an ideal material for precision instruments and aerospace applications. In this study, β-eucryptite was fabricated into an aerogel structure through the sol–gel process and supercritical drying method and using alumina sol as a cost-effective precursor. The synthesized β-eucryptite aerogel demonstrated unique properties including a negative thermal expansion coefficient (−7.85 × 10−6K−1), low density (0.60 g/cm3), and high specific surface area (18.1 m2/g). X-ray diffraction (XRD) and transmission electron microscopy (TEM) mutually corroborated the crystalline structure of β-eucryptite, with XRD confirming the phase purity and TEM imaging revealing well-defined crystal lattice characteristics. Combined nitrogen adsorption–desorption analysis and scanning electron microscopy observations supported the hierarchical porous microstructure, with SEM visualizing interconnected nanoporous networks and nitrogen sorption data verifying the porosity. The negative thermal expansion behavior was directly linked to the β-eucryptite crystal structure, as collectively validated by thermal expansion measurements. Additionally, Fourier transform infrared spectroscopy (FTIR) independently confirmed the aluminosilicate framework structure through characteristic vibrational modes. This research shows the innovation in the synthesis of β-eucryptite aerogel, especially its application potential in precision instruments and building materials that need low thermal expansion and high stability, and the use of aluminum sol as an aluminum source has simplified the preparation steps and reduced production costs.

The developed wearable electrochemical sensing platform demonstrates significant potential for continuous monitoring of cortisol in human sweat, a key biomarker for evaluating stress and fatigue levels in athletic performance. Utilizing a novel Au-decorated nanocomposite functionalized with β-cyclodextrin-assisted molecular recognition sites, this study outlines a systematic fabrication process where SiC nanoparticles are first oxidized and subsequently decorated with gold nanoparticles, achieving an average Au particle diameter of 5.3 ± 1.2 nm to enhance conductivity and electron transfer kinetics. The incorporation of dual amine-terminated β-cyclodextrin not only improves molecular recognition but also facilitates selective cortisol capture, as evidenced by sensitivity improvements to approximately 1.85 μF per ng/mL over a linear range of 5–45 ng/mL and a limit of detection as low as 2.8 ng/mL. Comprehensive electrochemical evaluations, including cyclic voltammetry, confirm the sensor’s ability to reliably distinguish cortisol from potential interferents, yielding selectivity coefficients between 18.3 and 31.0, with reproducibility demonstrated by relative standard deviations below 4.8 %. Real sweat sample analyses using a standard addition method provided a robust calibration curve (R² = 0.993), confirming effective quantification in complex biological matrices typical of athletic environments. Furthermore, the sensor exhibited excellent mechanical resilience, with a capacitance reduction of only 4 % after 20 bending cycles, and maintained stable performance over 30 days, indicating long-term durability suitable for wearable sports applications. This innovative approach integrates material design, surface chemistry, and device engineering to enable rapid, accurate, and noninvasive monitoring of athlete stress levels, offering a promising avenue for real-time physiological tracking during training and competitive performance.

In the field of lithium-ion battery (LIB) research, black phosphorus (BP) emerges as a promising anode material due to its high electrical conductivity and capacity. However, its significant volume expansion during cycling can lead to electrode pulverization and rapid capacity fade. In this study, a novel network binary polymer binder composed of carboxymethyl cellulose (CMC) and β-cyclodextrin (β-CD) is developed. Intermolecular forces crosslink CMC and β-CD, while strong intermolecular forces connect CMC and β-CD to BP. Graphite (G) is bonded to BP through P–C and P–O–C linkages, forming a composite anode. Research indicates that this intricate network structure effectively accommodates the volume changes of black phosphorus during charging and discharging, preserving the electrode structural integrity and enabling high reversible capacity. The CMC-β-CD electrode exhibits excellent cycle stability, maintaining a capacity retention rate of 70.3% after 300 cycles at 2 A g −1 , which is significantly higher than the electrodes using CMC (40.8%) and PVDF (40.6%) binders.
