Oxides with the ABO 3 chemical formula play a crucial role in studying photostriction in inorganic materials. In this study, the photostrictive behavior of ilmenite-type ceramics ATiO 3 (where A = Mg, Fe, Co, Ni, and Mn) was investigated under visible light irradiation. Among the ceramics investigated, CoTiO 3 showed the highest photostriction of approximately 0.1 % under 405, 520, and 650 nm light irradiation. The photostrictive response decreased successively in FeTiO 3 , MnTiO 3 , NiTiO 3 , and MgTiO 3 . Temperature and thermal expansion tests revealed that the deformation of the ceramics caused by the photothermal effect accounted for approximately half of their photostriction. Raman and charge transfer analyses indicated that the photostriction of the ceramics depended significantly on their crystal structure. Thus, the ceramics exhibited distinct photostrictive performances. This study highlights the connection between the crystal structure and photostrictive performance of ilmenite-type ceramics, providing valuable insights into the underlying mechanism of photostriction in inorganic materials.

Exchange bias (EB) effects play a crucial role in modern magnetic memory technology. Recently, the van der Waals heterostructures have shown potential for investigating mechanisms of the EB effect owing to their tunable physical properties and flexibility in fabrication. However, due to low magnetic ordering temperatures for most van der Waals magnets, establishing EB in van der Waals antiferromagnet/ferromagnet heterostructures at room temperature is challenging. In this study, we fabricate (Fe0.56Co0.44)5GeTe2 (FCGT)/Fe3GaTe2 (FGaT) heterostructures with magnetic ordering temperatures of each component well above room temperature to achieve a room-temperature EB effect. It is found that the sign and magnitude of the EB field can be efficiently controlled by manipulating the Néel order of FCGT. The manipulation of the Néel order shows significant magnetic field dependence. A strong preset field induces a switch in the Néel order of FCGT, which aligns the interfacial magnetization at the FCGT/FGaT interface, leading to robust EB, as revealed by both transport measurements and macrospin model calculations. Our findings demonstrate the intrinsic manipulation and switchability of room-temperature EB in all-van der Waals heterostructures and further emphasize the potential of two-dimensional spintronic devices.

Rheum tanguticum petiole juice, widely consumed in Tibet as both a vegetable and an herb, exhibits varying chemical compositions depending on the production methods. This study aims to identify the bioactive components in raw juice using ultra-performance liquid chromatography–quadrupole time-of-flight tandem mass spectrometry (UPLC–QTOF–MS–MS) and analyze their antidiabetic properties through network pharmacology. In addition, the effects of the three types of membrane clarification were evaluated. A total of 36 compounds were identified, and a components–targets–pathways–disease network was constructed for diabetes treatment. Among the membranes tested, the 0.2 μm microfiltration membrane exhibited the highest permeate flux and retained significant amounts of total flavonoids, phenolics, and proanthocyanidins, making it the optimal choice for juice clarification. These findings lay the groundwork for the industrial processing and utilization of R . tanguticum petiole juice in China.

The low efficiency of photogenerated carriers separation and slow cycling of Fe 2+ /Fe 3+ in Fe-based metal–organic frameworks (MOFs) have limited the improvement of their photo-Fenton activity. Therefore, in this work, MIL-100/BiOBr heterogeneous photo-Fenton catalyst was constructed by compositing MIL-100 with BiOBr nanosheets through a simple solvent evaporation method. In this system, the type II heterojunctions formed by the close contact of MIL-100 and BiOBr can promote the separation of photogenerated carriers and accelerate the redox cyclic of Fe 2+ /Fe 3+ , thereby significantly enhancing the photo-Fenton activity. Under visible light irradiation for 60 min, the best removal rate of tetracycline hydrochloride (TCH) by MIL-100/BiOBr is 94.3 %. Remarkably, the MIL-100/BiOBr exhibits a nearly fourfold increase in degradation rate constant compared to MIL-100 at photo-Fenton system. In addition, the catalysts can maintain high degradation performance over a wide pH range (3–9) and the co-existence of different anions. An in-depth investigation of the degradation mechanism reveals that superoxide radicals ( · O 2 – ) and hydroxyl radicals (·OH) play major roles in the photo-Fenton system. Based on this, the possible degradation pathways were proposed. Therefore, this study provides a new strategy for Fe-based MOFs to remove emerging pollutants from wastewater by photo-Fenton reaction.

Sulfur in petroleum coke poses significant environmental risks and damages equipment and carbon products, making its removal essential. This study presents a method for the desulfurization and modification of high-sulfur petroleum coke through catalytic roasting with reduced iron powder. The experimental results indicated that with a petroleum coke particle size of 75–58 μm, an iron powder-to-petroleum coke mass ratio of 50 %, and roasting at 1400 °C for 1 h, the desulfurization rate reached 87.93 %, reducing the sulfur content to 0.91 wt%, with a product recovery rate of 80.82 %. A series of characterizations of petroleum coke products before and after desulfurization were conducted, revealing that both the desulfurization efficiency and the graphitization performance of petroleum coke were significantly enhanced by the addition of iron powder. Additionally, density functional theory calculations for the pyrolysis of benzothiophene showed that the energy barrier for the pyrolysis process was reduced in the presence of Fe catalysis, theoretically confirming the desulfurization mechanism. The resulting low-sulfur petroleum coke products can serve as raw materials for graphite preparation.

The application of sodium sulfide (Na 2 S) as sulfidation reagent of zero valent iron (ZVI) has been well studied, however, the effect of Na 2 S existence on ZVI reactivity remains obscure. In this study, Ni(II) removal performance, mechanism, and stability by ZVI with Na 2 S were investigated at neutral condition. The results showed that Ni(II) removal sharply increased from < 5–100% by ZVI within 60 min with the increase of Na 2 S concentration, but the subsequent Ni(II) release occurred. In addition to the slight Ni(II) removal by Na 2 S in aqueous phase , Ni(II) was mainly removed by the adsorption and reduction by Na 2 S mediated ZVI system. Characterization analysis indicated that Na 2 S could lead to the severe Fe 0 corrosion and the main corrosion product on ZVI was lepidocrocite , which played the dominant role for Ni(II) immobilization. Meanwhile, the formation of iron sulfides on ZVI surface would enhance Ni(II) reduction and partially transform the adsorbed Ni(II) to NiS. Moreover, the higher ionic strength could further enhance the initial Ni(II) removal rate but the stability became poor. Regardless of the additive methods , the Ni(II) removal significantly enhanced in the system of ZVI and Na 2 S combination. Overall, this work reveals the sulfide mediated Fe 0 corrosion and provides a potential method for enhancing the reactivity of ZVI in the treatment of Ni(II) pollution.

Further enhancing the effective absorption bandwidth (EAB) and the harsh-environment stability of high-entropy alloy (HEA) electromagnetic-wave absorbing (EMA) materials is of great practical significance and broad application prospects. A new type of sulfur (S)-dissolved HEA EMA material was developed in this work. The flaky FeCoNiCuSx (x = 0, 0.05, 0.10, 0.20) HEAs were successfully prepared by a mechanochemical process. The phase structure, magnetic properties, corrosion resistance, oxidation resistance and EMA performances of the FeCoNiCuSx HEAs were investigated in detail and it was found that the introduction of S significantly optimized the impedance matching and achieved excellent EMA performances. The results showed that S10 (FeCoNiCuS0.10) had a minimum reflection loss (RL) of −65.20 dB and a wide EAB of 6.89 GHz. And the S20 (FeCoNiCuS0.20) achieved an ultra-wide EAB of 7.00 GHz and an RL of −55.40 dB in the C-band. In addition, the FeCoNiCuSx HEAs also exhibited excellent corrosion resistance. This work not only demonstrated the potential application of S-dissolved HEAs in the EMA field in harsh environments, but also provided new ideas for optimizing the electromagnetic impedance matching of HEAs.

The sustainable recycling of valuable metals from spent lithium-ion batteries (LIBs) is critical for resource conservation and environmental protection but remains challenging due to the complex coexistence of target and impurity metals. This study systematically investigates the selective leaching behaviors of metals (Co, Li, Cu, Fe, Al) in phosphoric acid media, revealing that lithium could be preferentially extracted in mild acidic conditions (0.8 mol/L H3PO4), while complete dissolution of both Li and Co was achieved in concentrated acid (2.0 mol/L H3PO4). Kinetic analysis demonstrated that metal leaching followed a chemically controlled mechanism, with distinct extraction sequences: Li > Cu~Co > Fe > Al in dilute acid and Cu > Al~Li > Fe > Co in concentrated acid. Furthermore, we developed a closed-loop process wherein oxalic acid simultaneously precipitates Co/Li while regenerating H3PO4, enabling acid reuse with minimal efficiency loss during cyclic leaching. These findings establish a single-step phosphoric acid leaching strategy for selective metal recovery, governed by tunable acid concentration and reaction kinetics, offering a sustainable pathway for LIBs recycling.

Emergent magnetism in 2D materials has attracted significant attention due to their intrinsic magnetic order, which persists down to the monolayer limit, and their potential applications in spintronic devices. In particular, domain structure modulation plays a crucial role in 2D magnet-based nano-spintronic devices. However, the fabrication and modulation of the desired domain structure, along with the establishment of reliable electrical write/read operations, remain significant challenges. Herein, a unique structure-shaping way to modulate domain structure is demonstrated via folding a continuous flat Fe 3 GaTe 2 nanosheet. Accompanied by magnetic domain structure transformation, the symmetric butterfly-shaped magnetoresistance (MR) curve changes to an antisymmetric field-dependent magnetoresistance. Notably, the MR exhibits either the same or opposite sign at geometrically equivalent positions, depending on the relative angle of the current flow and domain wall direction. The MR behavior with respect to sweeping field and electrodes position is due to the circulating current in the vicinity of the domain wall. More importantly, this new concept of manipulating domain structure and its associated magneto-transport behavior can inspire novel spintronic devices fabrication and application.

Two-dimensional ternary transition metal thiophosphites (MPS 3 ), as an emerging class of anode candidates for sodium ion batteries (SIBs), exhibit tremendous application potential. This study focuses on a series of 2D MPS 3 materials containing different transition metal elements (M = Mn, Fe, Co, and Ni) synthesized by the chemical vapor transport method. In-depth theoretical analysis employing density functional theory combined with crystal orbital Hamilton population reveals that NiPS 3 exhibits the lowest Na + diffusion barrier and the strongest Na + adsorption capability among the four materials. And these exceptional characteristics originate from the distinctive low-spin electronic configuration inherent in NiPS 3 , triggering a pronounced electronic repulsion between bridging Ni and S atoms, consequently diminishing the strength of Ni-S bonds and substantially enhancing the electrochemical reactivity. Furthermore, the S element in NiPS 3 exhibits a highest p-band center energy level in the four samples, resulting in a corresponding decrease in the occupancy of the Na-S antibonding sigma orbital, which in turn strengthens the interaction between S and Na + . This enhanced interaction significantly improves the adsorption capability of NiPS 3 towards Na + , effectively facilitating the charge transfer at the interface. Electrochemical test results indicate that NiPS 3 exhibits the most superior electrochemical performance among the four materials, maintaining a specific capacity of 500.7 mA h g −1 after 1100 cycles at 5 A g −1 . This study, through the profound integration of theory and experiments, fundamentally elucidates and verifies the underlying reasons for the superior properties of NiPS 3 in MPS 3 anodes.

This study developed novel polyferric titanium chlorides (PFTC) with varying Fe/Ti ratios and basicity (B) to achieve safe and effective surface water treatment. The formation of Fe-O-Ti was confirmed through the characterization of PFTC and its impact on physicochemical properties and coagulation performance was thoroughly investigated. Additionally, the molecular-level coagulation mechanism was elucidated. The results demonstrated that PFTC exhibited remarkable stability, with a distinct pH-stable phase during alkaline titration. PFTC showed excellent bridging adsorption capacity, achieving bovine serum albumin (BSA) removal efficiency of 78.33%. The flocculation rate increased to more than 222%, producing larger, denser flocs with superior settling performance, while posing no environmental risks to treated water. XPS and FTIR analyses revealed that hydrogen bond was the primary mechanism driving bridging adsorption. Molecular docking analysis indicated that PFTC hydrolysates formed stronger hydrogen bonds with higher binding energy at key BSA residues compared to polyferric chloride (PFC). According to XDLVO theory, the dominant hydrogen bond range between PFTC and BSA was more than 2.75 times greater than that of PFC and BSA. The hydrogen bond domain expansion effect, coupled with robust hydrogen bond, overcame distance barriers, enabling PFTC to establish strong bridging adsorption interactions with a broader range of BSA molecules, thereby enhancing coagulation efficiency. This study provides valuable insights into the interaction mechanisms between PFTC and BSA, supporting the practical application of polymeric metal composite coagulants.

Laterite nickel ore is rich in nickel and iron resources, and the nickel element is extracted in the form of nickel salt. However, the acid-leaching tailings of laterite nickel ore (LTLNO), which contain valuable iron resources, have not been cost-effectively recovered. In this work, we designed a novel method to extract iron from LTLNO and recycle it into high-valuable iron phosphate products using only phosphoric acid and iron powder. We explored the effects of reaction parameters, such as phosphoric acid concentration, iron powder dosage, time, and temperature, on the leaching behavior of key elements. The results showed that the iron leaching rate was as high as 96.54 % when using 3.5 mol/L phosphoric acid with a liquid-to-solid ratio (L/S) of 5 mL/g and an iron powder dosage based on the Fe/Fe n+ ratio of 0.5 after 3 h at 25 °C, and a final high-purity FePO 4 (99.4 %) was obtained. Kinetic analysis revealed that the leaching reaction was controlled by the diffusion through the neogenetic layer, and the leaching reactions were thermodynamically favorable. This method allows for a simpler and more efficient recovery of iron and the products of higher-value iron phosphate products than other LTLNO recycling technologies. Additionally, it offers a total economic benefit of $134/t for LTLNO treatment, demonstrating great prospects for industrial application.
