The first borate featuring a three-dimensional B–O anionic network with edge-sharing (ES) [BO4] units, Pb2.28Ba1.72B10O19 (PbBaBO), has been synthesized under ambient pressure. The squeezing effect of the 2∞[B10O19] bilayer structure on the intra-layer co-edge [BO4] leads to an extremely long B–B distance and quite small internal O–B–O angles in the [B2O6] ring.

Oxidative dehydrogenation (ODH) of ethylbenzene is a promising process for styrene production. However, its application is limited by product overoxidation and purification requirements due to the co-feeding of mild oxidants. Herein, we report a facile manganese-based catalyst (K/Mn 3 O 4 -Al 2 O 3 ) and achieve competitive styrene selectivity of 88 % and ethylbenzene conversion of 95 % at 450 ℃ (84 % yield vs. ∼ 60 % yield in commercial dehydrogenation process at 600 ℃) under a cyclic redox ODH scheme. The introduction of Al 2 O 3 into MnO x restructures composite oxides and depresses bulk lattice-oxygen migration for the partial oxidation of ethylbenzene. The surface modification using potassium creates reactive sites and regulates surface properties, achieving ethylbenzene activation and high conversions. Highly active lattice oxygen in catalysts after bulk and surface modifications selectively converts ethylbenzene to styrene and water. This study provides an understanding of roles of manganese-based catalysts in styrene generation and offers a strategy to modulate lattice oxygen on catalysts.

In this research, solid-liquid equilibrium for the ternary system (2-naphthaldehyde + o -phthalic anhydride + 1,4-dioxane) was measured at 283.15 K, 293.15 K and 303.15 K, respectively. Three isothermal phase diagrams of the system were plotted using the values of the experimental solubility. Pure 2-naphthaldehyde and o -phthalic anhydride were formed at (283.15, 293.15 and 303.15) K, and were determined by Schreinemaker’s wet residue method. The crystallization region of o -phthalic anhydride was found to be much larger than that of 2-naphthaldehyde at a certain temperature. The experimental solubility at multiple temperatures was correlated by the NRTL and Wilson models. The NRTL model was more accurate than the Wilson model in this system. The diagram of density versus component was also constructed.

Improved capability to inhibit degradation of trianionic curcumin has been realized in this study. The interaction between trianionic curcumin (Cur 3− ) and gemini dodecyl or tetradecyl O -glucoside micelles , tetradecyltrimethylammonium chloride (TTAC) or hexadecyltrimethylammonium bromide (CTAB) micelles as well as gemini alkyl O -glucosides (AGs)/alkyl trimethyl ammonium halides mixed micelles have been characterized. It is demonstrated that Cur 3− cannot be incorporated into gemini AGs micelles since the lack of electrostatic attraction and degraded as rapidly as in aqueous phase. Cur 3− tend to reside at palisade layer − water interface of TTAC or CTAB micelles due to the strong electrostatic interaction while moderate electrostatic interaction allows Cur 3− to locate more deeply in the palisade layer of mixed micelles. Additionally, mixed micelles tend to form a more compact and hydrophobic palisade layer than pure TTAC and CTAB ones. These factors bring about enhanced fluorescence intensity and blue − shift of emission maxima, improved fluorescence anisotropy and quantum yield, as well as reduced decay rate of Cur 3− in mixed micelles than in pure TTAC and CTAB ones.

Argyrodite sulfide solid electrolytes, such as Li6PS5Cl (LPSC), have received much attention due to their high ionic conductivity (>1 mS cm–1) and success in all-solid-state batteries (long cycle performance, high energy density, etc.). Numerous efforts are spent on modifying the properties of the electrolyte itself. Here, we combine first-principles calculations with experiments to investigate O-doped argyrodite sulfide solid electrolytes (Li6PS5–xClOx,x = 0–1). It is found that Li6PS4.75ClO0.25 (LPSCO0.25) with x = 0.25 and cubic phase (F4̅3 m) shows the highest ion conductivity of 4.7 mS cm–1 (cold-pressed), higher than that of undoped Li6PS5Cl (4.2 mS cm–1). The bare LiCoO2/LPSCO0.25/Li–In all-solid-state battery exhibits an initial capacity of 131 mA h g–1 at 0.1 C and satisfactory cycling stability with 86% capacity retention after 250 cycles to the 4th cycle at 0.3 C under 25 °C. In addition, the NCM811/LPSCO0.25/Li–In cell is assembled using bare LiNi0.83Co0.06Mn0.11O2 cathode and shows an initial discharge capacity of 181 mA h g–1 at 0.1 C and 160 mA h g–1 at 0.3 C. The doping of oxygen-forming Li6PS5–xClOx also improves the stability to Li metal, proven by cyclic voltammetry and powder X-ray diffraction tests. The calculation results for the band structure reveals that LPSC has the lowest unoccupied molecular orbital than LPSCO0.25, further confirming the above conclusion.

Protein glycosylation plays essential roles in various biological processes, and thus determining the glycan structure present on the protein is essential to comprehensively understand these events. However, distinguishing saccharide stereoisomers is challenging, especially when their structures are very similar and their molecular weight and potential glycosylation sites are identical. One representative example is O-linked β-N-acetylglucosamine (O-GlcNAc) and O-linked α-N-acetylgalactosamine (Tn antigen). Traditional biochemistry approaches used in separating O-GlcNAc- and Tn antigen-modified peptides mainly include chemical derivatizations, lectins, and antibodies. However, subsequent mass spectrometry (MS) analysis is still required if one aims to determine the exact glycosylation site. Herein, a straightforward approach using the ratio of relative abundance (RA) of two fragment ions (RA126.055/RA138.055) in higher-energy collisional dissociation (HCD) MS without relying on the traditional biochemistry technique is reported to discriminate between O-GlcNAc and Tn antigen. This ratio was verified by synthetic glycopeptides and proteomic analysis in HeLa cells, where 10 proteins were found to be O-GlcNAcylation and 4 proteins were found to be Tn antigen-modified. Overall, this method can be extensively employed in liquid chromatography–mass spectrometry (LC-MS)-based proteomic studies and thus is of importance in biological and biomedical research.

Rational microstructure design and compositional regulation have emerged as effective pathways to enhance electromagnetic wave (EMW) absorption, However, simultaneously achieving strong absorption, broad bandwidth, thin thickness and low filler loading remains challenging. Herein, three-dimensional hierarchical heterostructures comprising amorphous carbon-wrapped magnetite supported on flower-like reduced graphene oxide (Fe₃O₄@C/FRGO) was constructed through spray-drying assembly, spatially confined solvothermal crystallization, and defect-modulated carbonization. By tailoring the reduction degree of FRGO and tuning ferrite composition through thermal treatment, the dielectric-magnetic properties and interfacial interactions are precisely regulated. With merely ≈ 3.26 wt% incorporation of FRGO, the optimized composite exhibits a minimum reflection loss (RL min ) of -66.29 dB at 1.94 mm (20 wt% filler) and a broad effective absorption bandwidth (EAB) of 6.60 GHz (11.30–17.90 GHz) at 2.73 mm (30 wt% filler). This exceptional performance is attributed to the engineered heterointerfaces that facilitate multi-path energy dissipation via magneto–dielectric coupling optimized impedance matching, intensive interfacial polarization from abundant hierarchical architectures and the flower-like structure induced multiple scatterings. This study highlights the pivotal role of interfacial engineering in heterostructured absorbers and offers a design paradigm for high-performance EMW-absorbing materials through coordinated component–structure modulation.

In this work, a novel ternary heterojunction consisting
of Zn vacancy-rich
zinc oxide (Zn 1– x O), a zeolitic
imidazolate framework-8 (ZIF-8), and cobalt phthalocyanine (CoPc)
was fabricated for photocatalytic N 2 fixation. The Zn 1– x O/ZIF-8 composite with bridged O–Zn–N
bonding was synthesized via in situ growth of ZIF-8 on Zn 1– x O, and it possessed a large surface area favorable
for N 2 adsorption. The incorporation of CoPc with dispersed
Co–N 4 (II) sites enhanced light harvesting and N 2 activation. Zn vacancies and coupled type II/Z-scheme charge
transfer pathways in the heterojunction accelerated the separation
of photogenerated charge carriers. As a result, the optimized catalyst
exhibited superior and stable photocatalytic N 2 reduction
performance via an alternating pathway in water, with an NH 4 + production rate of 65.2 μmol g –1 h –1 , which is 17.0 times higher than that of ZnO.
This study develops a novel ZnO-based heterojunction that simultaneously
optimizes multiple key factors for efficient photocatalytic N 2 fixation.

Electrochromic supercapacitors (ECSCs) find extensive applications in flexible wearable, self-powered smart windows because of their visual energy storage characteristics. ECSCs simultaneously achieve rapid response, high transmittance and high specific capacity. Due to O, S heterocycle with more electron cloud which will bring more electroactive properties, two monomers and a series of polyamides (PAs) films containing furan, thiophene blocks (named as PA1, PA2, PA3, PA4, PA5 and PA6) are designed and synthesized. All the six PAs demonstrate a colorless to dark green/dark blue, while PA2 shows an initial optical contrast of 86 %, bleaching time (t b ) and coloring time (t c ) of 0.9 s and 1.2 s. Simultaneously PA2 delivers a specific capacitance of 197.2F g −1 at a current density of 1 A g −1 . When the current density rises to 20 A g -1 from 1 A g −1 , its capacitance retention rate remains at 79 % of its initial capacitance after undergoing 3000 charge–discharge cycles. ECSCs with PA1, PA2 assembled exhibit a ΔT of 70 % and 76 %. The ECSCs have a specific capacitance (60.1F g −1 and 69.1F g −1 at 1 A g −1 ), with 70 %, 69 % of initial specific capacitance following 2000 consecutive charge–discharge cycles. These PAs containing O, S heterocycle cores demonstrate promising prospect for ECSCs.

Ruthenium oxide is among the most active electrocatalysts for the acidic oxygen evolution reaction (OER), yet its practical use is severely limited by anodic over-oxidation, lattice-oxygen participation, and the resulting Ru dissolution. Here, we report a monolithic RuO 2 -TiO x /Ti anode directly constructed on Ti felt through a one-step impregnation-calcination strategy, in which the native surface oxide evolves at only 400 °C into a rutile-like TiO x interlayer that is lattice-matched with rutile RuO 2 . The resulting structurally defined RuO 2 -TiO x heterointerface induces interfacial charge redistribution and tensile lattice distortion, thereby modulating the Ru–O coordination environment, attenuating Ru–O covalency, and suppressing excessive lattice-oxygen participation. Operando spectroscopy, isotope-labeling analysis, electrochemical probing, and theoretical calculations collectively reveal that such interfacial regulation shifts acidic OER toward the adsorbate-evolution mechanism while suppressing Ru overoxidation and local structural reconstruction. Beyond active-site modulation, the integrated TiO x interlayer and metallic Ti scaffold provide robust interfacial adhesion, efficient electron transport, and favorable gas/liquid transport under high-rate operation. As a result, RuO 2 -TiO x /Ti delivers an overpotential of 172 mV at 10 mA cm −2 , sustains 50 mA cm −2 for 1000 h with only 18 ppb Ru dissolution, and enables proton exchange membrane (PEM) water electrolysis at 1.65 V at 1 A cm −2 . This work highlights lattice-matched heterointerface engineering as an effective strategy for durable acidic OER electrodes. The lattice-matched RuO 2 -TiO x heterointerface induces charge redistribution and tensile distortion, elongating Ru–O bonds, reducing covalency, and suppressing lattice-oxygen participation for highly active and durable acidic oxygen evolution reaction (OER).

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.

A polystyrene-based foam with excellent mechanical properties was prepared. • The synergistic effect of low surface energy and micro-nano rough structure provides excellent anti-adhesion performance against high-temperature oil and water, enabling the material to effectively separate high-temperature emulsions. • The high tortuosity factor of the 3D microporous material ensures high separation efficiency, while the fluid shear force generated under applied pressure effectively expels the demulsified internal phases, thereby ensuring long-term separation of high-temperature emulsions. The separation of water from high-temperature emulsions in real time remains highly challenging due to the potential failure of material wettability. In this study, we develop a thermally stable oleophobic/hydrophobic microporous polystyrene-based foam (FPEI/MoS 2 PS foam) by combining a low-surface-energy fluorinated coating with a micro-nano rough structure. The foam was fabricated via a high internal phase emulsion (HIPE) templating method to construct a 3D microporous structure. Subsequently, MoS 2 was grown on the foam skeleton through a hydrothermal process, followed by the covering of a fluorinated polyethyleneimine (FPEI) functional coating. The resulting foam exhibits a rough microporous structure and thermally stable oleophobic/hydrophobic wettability (WCA and OCA above 128° even at 90 °C). Within a temperature range of 60–90 °C, the material effectively separates surfactant-free emulsions, surfactant-stabilized emulsions, and real industrial emulsions from diesel cracking processes. For W/D ⁎ (surfactant-free water in diesel emulsion), W/D (surfactant-stabilized water in diesel emulsion) and real industrial emulsions at 90 °C, the permeation flux reached 4600, 3050, and 1700 L m −2 h −1 , respectively, with all separation efficiencies exceeded 98%.
