The aqueous zinc ion battery (AZIB) has been widely studied due to its rapid kinetics and high specific capacity attributed to the chemical insertion of H + protons. However, the current research landscape lacks comprehensive investigations into copper-based sulfide materials and the intricate co-embedding/extraction mechanism of H + /Zn 2+ . In this study, we employed an innovative in-situ etching method to synthesize a current collector-integrated Cu@Cu 31 S 16 cathode material. Cu 31 S 16 not only exhibits excellent stability and conductivity but also activates proton insertion chemistry. Consequently, we have demonstrated, for the first time, efficient and reversible co-embedding/extraction behavior of H + /Zn 2+ in Zn-Cu 31 S 16 batteries. Specifically, owing to the lower charging and discharging plateaus of zinc ions (0.65 V, 0.45 V) compared to H + (0.97 V, 0.84 V) in Zn-Cu 31 S 16 batteries, two distinct plateaus were observed. Moreover, we delved into the mechanism of ion co-embedding/extraction by exploring different ions (Zn 2+ , H + /Zn 2+ , H + ) within varying voltage ranges. This exploration led to the development of three types of ion batteries, where Zn 2+ , H + /Zn 2+ , and H + exhibit co-embedding/extraction within voltage ranges of 0.3–0.9 V, 0.3–1.05 V, and 0.5–1.05 V, respectively. These batteries have achieved impressive performance with specific capacities of 282.74 mAh g −1 , 587.4 mAh g −1 and 687.3 mAh g −1 , respectively. Introducing the concept of “Voltage-Selective Ion Co-Embedding/Extraction”, this study broadens the research scope of AZIBs . This research not only offers a feasible solution and theoretical guidance for future proton batteries but also underscores the tremendous potential of AHPB.

Polar-embedded stationary phases are superior to conventional alkyl stationary phases in terms of water-wettability, silanol activity and polar selectivity. A novel method was proposed for efficient preparation of amide-embedded stationary phases bearing extended aliphatic chain and large aromatic ring. The present approach, which simply required isocyanate and desired carboxylic acid, rather than the normal combination of amine/acyl chloride/proton scavenger, produced aromatic pyrenyl amide-embedded (PYE-Amide) and aliphatic docosanyl amide-embedded (C22-Amide) stationary phases. The as-synthesized packing materials were characterized and evaluated in comparison with conventional octadecyl stationary phases in terms of bonding density, aromatic and hydrophobic natures, charge-transfer capability, and selectivity towards isomers of various unsaturated compounds. A high affinity of the unsaturated ligand for the unsaturated solutes, especially the electron-deficient ones, was observed. The PYE-Amide stationary phase exhibited unique aromaticity-dependent shape selectivity, which was beneficial to the resolution of certain geometric isomers of polycyclic arenes. The applicability of such stationary phases was demonstrated by effective separations of estrogens and sulfonamide drugs.

A magnetic hybrid material (Fe3O4-embedded-MOF) consisting of a stable metal–organic framework HKUST-1 embedded with poly(N-vinyl-2-pyrrolidone) coated Fe3O4 microspheres was simply prepared under refluxing conditions for 4 h. The as-synthesized material was characterized using powder X-ray diffraction, scanning electron microscopy (SEM), vibrating sample magnetometry (VSM), energy dispersive spectroscopy (EDS) and N2 adsorption–desorption at 77 K. The hybrid material was studied for the adsorption of methylene blue from aqueous solution. The effects of dye concentration, adsorbent dose, and initial pH on the adsorption of methylene blue were measured, and from these experimental data, adsorption isotherms, kinetics, and thermodynamics were obtained. The results showed that a pseudo-second-order kinetic model and Langmuir isotherm (with R2 = 0.937) matched well for the adsorption of methylene blue onto Fe3O4-embedded-MOF. Thermodynamic parameters including free energy, enthalpy, and entropy of methylene blue adsorption were calculated, and the results showed that the adsorption of methylene blue were favorable on Fe3O4-embedded-MOF. The magnetic hybrid Fe3O4-embedded-MOF material features both magnetic separation characteristics as well as excellent adsorption performance for methylene blue in aqueous solution. The results of the present study demonstrate that Fe3O4-embedded-MOF is a promising adsorbent for the removal of dye from wastewater.

In miniature ion trap mass spectrometry, achieving a balance between isolation resolution and efficiency is a formidable challenge. The presence of absorption curves causes target ions to inadvertently absorb energy from AC signal components near their resonant frequencies. To mitigate this issue, SAM–SFM waveforms introduce a parameter known as the decreasing factor. Unlike SWIFT waveforms, SAM–SFM’s spectral profile intentionally departs from a rectangular window, adopting an arch-shaped excitation window to minimize the impact on target ions and improve ion isolation efficiency. SAM–SFM waveforms have the advantage of low computational complexity, enabling real-time computation using an embedded FPGA technology. Regardless of any parameter changes, the FPGA can consistently guarantee waveform output within 1 μs. This not only enhances throughput but also eliminates the need for a PC in miniature mass spectrometry devices. The performance of SAM–SFM has been validated on an improved “Brick” miniature ion trap mass spectrometer. Comparative experiments with SWIFT waveforms confirm the lossless unit-mass isolation capabilities of SAM–SFM. This waveform has the capability to simultaneously isolate multiple target ions, even allowing for the lossless isolation of ions with lower abundance within isotopic clusters, albeit at the cost of requiring extended isolation durations.

Loading noble metal on the surface has been widely used to improve photocatalytic activity of semiconductor photocatalyst. Here, Pt-embedded anatase (A)-rutile (R) TiO 2 junction photocatalyst (A/Pt/R) was found to show much more efficient photocatalytic H 2 evolution activity than the other TiO 2 photocatalysts loading Pt on the outside surface (such as Pt/A/R, Pt/A, Pt/R and Pt/P25), although the as-embedded Pt is unreachable to reactants. The A/Pt/R sample shows a photocatalytic H 2 evolution rate as high as 17.9 mmol⋅g cat −1 ⋅h −1 , which is 27.2 and 2.5 times higher than the common A/R and Pt/A/R samples, respectively. The traditional theory fails to explain the unexpected high photoactivity. The reverse tandem Schottky junction is suggested to be possibly responsible for the high photoactivity of A/Pt/R, which allows the photogenerated electrons to transfer more swimmingly from rutile to anatase than the common A/R phasejunction. This finding provides a new strategy for further promoting photocatalytic activity of Pt/TiO 2 and other heterophase or heterojunction photocatalysts.

Embedding enzyme in biodegradable polyester accelerates hydrolysis in environments it ends up, but the release of microplastics (MPs) and nanoplastics (NPs) during this process remains underexplored. This work investigated the evolution of MPs and NPs released from poly(ε-caprolactone) (PCL) with embedded Lipase PS. The embedded enzyme significantly accelerated hydrolysis, causing the PCL film to disappear within 96 h. Notably, the formation rates and quantities of MPs and NPs were much higher compared to film with external enzyme. At 96 h, MPs (3.55 ×10 5 particles/mL) was 2.4 times, and NPs (4.65 ×10 7 particles/mL) was an order of magnitude higher than that with external enzyme. After 130 days, although both quantities and average size of MPs and NPs decreased due to only 90.6 % of enzymes were detected leaking, they did not completely disappear. The quantities of MPs and NPs were comparable to that with external enzyme, and the average size of MPs remained 1 μm. The simultaneous erosion inside film macroscopically, and severe chain cleavage microscopically, contributed to feasible film disintegration and formation of high amounts MPs and NPs. These findings underscore the importance of managing the release of MPs and NPs during the hydrolysis of enzyme-embedded biodegradable polyesters to ensure safety and mitigate environmental impact.

Owing to the low-cost, dendrite-free formation, and high volumetric capacity, rechargeable Li + /Mg 2+ hybrid-ion batteries (LMIBs) have attracted great attention and are regarded as promising energy storage devices. However, due to the strong Coulombic interaction of Mg 2+ with host materials, the traditional “Daniell Type” LMIBs with only Li + intercalation usually cannot ensure a satisfactory energy density. Herein, graphene monolayers are arranged intercalating into MoS 2 interlamination to construct van der Waals heterostructures (MoS 2 /G VH). This operation transforms the construction of ion channels from pristine interlamination of two MoS 2 monolayers to the interlamination of MoS 2 monolayer with graphene monolayer, thereby greatly reducing ion diffusion energy barriers. Compared with pristine MoS 2 , the MoS 2 /G VH can obviously reduce the migration energy barriers of Li + (from 0.67 to 0.09 eV) and Mg 2+ (from 1.01 to 0.21 eV). Moreover, it is also demonstrated that MoS 2 /G VHs realize Li + /Mg 2+ co-intercalation even at a rate current of 1000 mA g −1 . As expected, the MoS 2 /G VH exhibits superior electrochemical performance with a reversible capacity of 145.8 mAh g −1 at 1000 mA g −1 after 2200 cycles, suggesting the feasibility of potential applications for high-performance energy storage devices.

The most common yellow phosphor for wLEDs, Y3Al5O12:Ce3+ (YAG:Ce3+), suffers from a deficiency of red in its spectral content of light. In this paper, a new strategy is provided to tailor the Ce3+ spectral profile through surface-located dye molecules of ATTO-Rho101, which feature intense, broad absorption in the green-yellow spectral region of Ce3+ emission as well as bright red emission. Sphere-shaped and highly dispersed micrometer and nanometer-sized YAG:Ce3+ (micro/nano-YAG:Ce3+) was synthesized through a modified solvothermal method. Surface SiO2 coating and simultaneous dye embedding were performed on the solvothermally derived YAG:Ce3+, heat-treated micro-YAG:Ce3+ and commercial phosphors. Efficient radiative transfer/reabsorption from Ce3+ in the inner core of YAG to the dye molecules in the SiO2 outer shell, irrespective of the size of the phosphors, was demonstrated in the accumulated YAG:Ce3+@SiO2 + dye powder upon blue light excitation; this enhanced its red emission. Fluorescence microscopy was demonstrated to be a powerful tool to identify the reabsorption phenomenon of the powdered materials. Packaging the heat-treated micro-YAG:Ce3+@SiO2 + dye phosphors on blue LED chips yielded a warm wLED (Ra ∼ 93), but an Ra of only ∼79 was obtained for the wLED with commercial YAG:Ce3+@(SiO2 + dye)5 due to the low concentration of phosphors dispersed in the epoxy resin and the resulting decreased reabsorption by dye molecules. Surface-protonated amine species were found to induce Ce3+ → Ce4+ oxidation upon activation by heating or photoirradiation and then quench the photoluminescence (PL) of micro-YAG:Ce3+ even after surface modification by SiO2, YAG or being embedded in an epoxy resin matrix. High calcination temperatures greatly improved the PL stability of micro-YAG:Ce3+ through the removal of surface-capped species. The dye in the silica matrix showed high stability against heating and irradiation due to the so-called “caging effects”; however, decreased photo-stability was found in commercial YAG:Ce3+@(SiO2 + dye)5 due to the incomplete and/or loose SiO2 layer grown during multiple surface modifications.

Electrochemical intercalation behavior of anions into the graphite electrode is very complex, which can be governed by the solvation structure of the electrolyte in contact with the graphite electrode. Although extensive investigations have primarily focused on single-solvent electrolyte systems, the synergistic intercalation of multiple solvents with anions remains poorly understood. Herein, we demonstrate the synergistic intercalation of the tetrafluoroborate anion together with two different kinds of solvents, ethylene carbonate (EC) and ethyl methyl carbonate (EMC), from the solutions of LiBF4-EC/EMC into natural graphite. This intercalation process exhibits a unique continuous structural change of the anion-graphite intercalation compounds (AGICs), in stark contrast to the conventional two-phase transitions in AGICs. In situ X-ray diffraction (XRD) analysis reveals a progressive transition in AGICs with their intercalation gallery heights (IGHs) gradually contracting from 0.81 to 0.77 nm in a specific LiBF4-EC/EMC solution. The formation conditions of this synergistic cointercalation phenomenon have been systematically addressed.

The bismuth-embedded columnar activated carbon (Bi-AC) composite was prepared by the method of self-reduction and investigated for trapping I 2 and CH 3 I. Our findings showed that the bismuth-based compounds mainly existed as simple substance in Bi-AC. The elemental bismuth was regularly spherical in the shape, and mostly embedded on the surface of activated carbon, seldom inside of activated carbon. The capture capacities of I 2 and CH 3 I by the Bi-AC composite was 569.0 ± 14.2 and 232.1 ± 17.7 mg/g, respectively, which was better than that of the commercial silver-based materials. I 2 was trapped to form I 5 - and Bi(IO 3 ) 3 , while CH 3 I was catalytically cleaved to form BiOI and I 5 - . The Bi-AC composite is expected be used as adsorbents of 129 I to replace silver-based materials due to its high performance and low cost.

A facile and scalable polymer bubbling technique was used to fabricate three-dimensional nickel-embedded nitrogen-doped porous carbon foams (3D Ni@NPCFs) exhibiting high-performance electromagnetic wave absorption. The 3D Ni@NPCFs were characterized by their unique 3D interconnected porosity and the cooperative effect of conductive magnetic Ni nanoparticles and nitrogen incorporation. The optimal sample achieved reflection loss (RL) of -47.20 dB at 6.05 GHz and an effective absorption bandwidth (EAB) of 7.4 GHz within the absorber thickness of 3.0 mm. This superior performance is attributed to the unprecedented synergistic interplay between the tailored 3D porous network, which facilitates multiple scattering and prolonged wave propagation, and the embedded Ni nanoparticles coupled with nitrogen doping, which enhances both the magnetic and dielectric losses. Furthermore, the optimal sample demonstrated a simulated radar cross-sectional reduction of up to 28.43 dBm 2 . The 3D Ni@NPCFs show great promise as high-performance absorbers for electromagnetic protection applications.

A facile solvothermal approach was used to prepare brookite-type TiO 2 nanocrystals with different phase content and structure, accomplished by adjusting the ratio of TiCl 4 to t -BuOH. The obtained biphasic brookite/rutile TiO 2 nanocrystals showed a high brookite weight content (72%). The photocatalytic degradation of phenol under UV-irradiation was used to determine the synergetic effect from the combination of different phases ( e.g. , brookite, anatase, and rutile). The biphasic NST-4 composed of brookite and rutile exhibited the highest degradation rates, with rate constants three times higher than commercial Degussa P-25. Detailed analysis found that, besides phase composition and content, the semi-embedded structure was essential to obtain a superior activity of biphasic TiO 2 samples.
