Growing tungsten disulfide (WS 2 ) on self-supporting carbon fiber cloth is an effective means to enhance the sodium storage. However, it is difficult for WS 2 to exhibit high stability and fast reaction kinetics on the surface of carbon fiber cloth. Herein, we construct a composite structure that WS 2 nanosheets are grown on the surface of carbon fiber cloth with many gaps. These gaps are poured by pyrolytic carbon structure. The composite structures expose lateral (0 0 2) crystal plane of WS 2 nanosheets (WS 2 /CFC@C-P). When WS 2 /CFC@C-P is evaluated as an anode material for sodium-ion batteries (SIBs), the exposed (0 0 2) lateral edge realizes the rapid migration of Na + with fast reaction kinetics. Moreover, the poured carbon stabilizes expanded WS 2 nanosheets to maintain original structure. Under the above merits, WS 2 /CFC@C-P could provide high reversible capacity (672 mAh g −1 after 200 cycles at 100 mA g −1 ) and rate capacity (657 mAh g −1 at 0.1 A g −1 and 230 mAh g −1 at 2 A g −1 ). Furthermore, they deliver 297 mAh g −1 after 500 cycles at 2 A g −1 with a low capacity fading of 0.96% per cycle. This work provides a new insight to develop high performance SIBs by introducing the fine regulation of carbon layer.

The role of the Ni3S2 layer on Ni particles in the electrochemical performance of Na/NiCl2 cells with the addition of sulfur into the cathode is studied. It was found that the Ni3S2 layer could be in situ generated on nickel particles and exhibit a self-repairing function during cycling when sulfur exists in the cathode due to the reaction between the sulfur and nickel particles. The self-repairing function of the Ni3S2 layer could enhance the blocking effect and improve the battery cycle performance. The capacity of the cell with the optimum amount of sulfur (with self-repairing function) after 50 cycles is about 12% greater than that of the cell with the optimum level of Ni3S2 (without self-repairing function). The effect of the self-repairing function of the Ni3S2 layer is determined by the amount of sulfur in the cathode.

The continuous exploration of multinary chalcogenide semiconductors has provided a variety of new functional materials. In this paper, four new quaternary chalcogenides AHgPS4 (A+ = Na+, K+, Rb+, Cs+) have been prepared by solid-state syntheses. These findings complement the lack of research on this quaternary system. Influenced by the size effect of cations and the coordination mode of Hg, the four compounds crystallize in four different space groups [NaHgPS4, P4̅n2; KHgPS4, Pnn2; RbHgPS4, P21/n; CsHgPS4, P212121] and show an interesting evolution from a 3D framework structure to a 1D chain structure. Moreover, all of these compounds feature noncentrosymmetric (NCS) structures except for RbHgPS4. The materials exhibit wide band gaps of 2.7 eV < Eg < 3.0 eV. The NCS- related second-harmonic-generation (SHG) property of NaHgPS4 and KHgPS4 was also studied. They display strong powder SHG responses (3.14 × AgGaS2 for NaHgPS4; 4.15 × AgGaS2 for KHgPS4), which indicate their intriguing potential as IR nonlinear-optical materials. Moreover, first-principles theoretical calculations were performed to understand the structure–property relationships of these materials.

Composite cathodes have attracted great attention due to the integrated advantages of each pure structure. Also, the component ratio deserves a careful modulation to further improve the corresponding electrochemical performance. Mn-based layer–tunnel hybrid composite became a focus in sodium-ion batteries due to the superiority in terms of high performance, low cost, and nontoxicity. In the previous reports, the structure modulation was carried out via changing the synthesis condition, varying the transition-metal-element ratio, and different ion doping. Also, it is still challenging to explore a more feasible method to simplify the adjustment process. Herein, we introduced Mg2+ into Na sites or transition-metal sites in Na0.6MnO2 and first discovered the doping-site-variation-induced structural adjustment phenomenon. Specifically, Mg doping in transition-metal sites could be beneficial for the growth of the P2-type structure, while layer/tunnel component ratio decreased when locating Mg2+ in Na sites. The P2–O2 phase transformations could be effectively suppressed by locating Mg2+ in both sites in high-voltage regions and thus improve the cycling performance. The designed material, Na0.6Mn0.99Mg0.01O2, could attain a decent capacity of 100 mA h g–1 at 1000 mA g–1 and a satisfied retention of 76.6% after 500 cycles. Additionally, ex situ X-ray diffraction analysis experiments verify the excellent structural stability of Mg-substituted samples during charge–discharge processes. Moreover, the Na0.6Mn0.99Mg0.01O2 also displays superior sodium-ion full-cell properties when merged with hard carbon anode. Thus, this research may indicate a proper novel thread for designing high-performance composite electrodes.

High-safety and low-cost Na 4 Fe 1.5 Mn 1.5 (PO 4 ) 2 (P 2 O 7 ) (NFMPP) is a highly promising cathode for Na-ion batteries (SIBs), offering a higher energy density than typical NFPP. However, its performance is hindered by Na/Mn anti-site defects and Jahn-Teller (J-T) distortion, resulting in voltage hysteresis and sluggish Na-ion diffusion kinetics. Herein, we demonstrate a high-rate and long-life NFMPP cathode by synergistically optimizing the initial molar ratio of Na-ion to transition metal (Na/TM) and vanadium (V) doping. The Na/Mn anti-site defects have been greatly alleviated from 5.9 % to 2.2 %, effectively suppressing the voltage hysteresis of Mn 2+ /Mn 3+ redox plateau. Meantime, the electron-rich V doping with strong V-O bonds (541 kJ/mol) exhibits strong interaction with Mn, significantly reducing the effect of J-T distortion on Na-ion diffusion. As a consequence, the optimized NFMPP cathode delivers a superior initial charge capacity of 115.1 mAh/g at 0.1C and achieves a high reversible energy density of 334 Wh/kg, surpassing many reported phosphate-based cathodes. It also exhibits exceptional cycling stability, retaining 94.1 % of its capacity after 500 cycles, making it a highly competitive candidate for next-generation SIBs.

To address the issues of low activity and poor stability of manganese-based catalysts in the catalytic degradation of refractory volatile organic compounds such as chlorobenzene (CB), this study designed a sodium-doped Mn-Cu bimetallic catalyst supported on hydroxyl-rich pseudo-boehmite (PB), denoted as Na-CuMnO x /PB, depending on the route of “support hydroxylation, bimetallic synergy, and alkali metal modification”. The catalyst achieved highly efficient degradation of CB under room temperature with the non-thermal plasma assistance. The PB support significantly increased surface hydroxyl groups and acidity. MnO x /PB showed a degradation efficiency of 85.14 %, superior to the 73.98 % achieved by a conventional Al 2 O 3 -supported catalyst. Cu doping promoted the formation of a Mn-Cu synergistic structure, increasing the surface-adsorbed oxygen to 56.59 % and the Mn(IV)/Mn(III) ratio to 0.63, thereby improving the degradation efficiency to 92.02 %. However, chlorine deposition (Cl content: 3.91 %) caused rapid deactivation. After Na modification, the Na-CuMnO x /PB catalyst exhibited a further increased Mn(IV)/Mn(III) ratio of 0.79, enhanced weak basic and acidic sites. The abundant surface hydroxyl groups and alkaline sodium hydrolysis facilitated HCl generation, achieving an HCl selectivity of 40.95 % with surface chlorine deposition as low as 0.59 %, thereby enabling the catalyst to maintain a degradation efficiency of 95.95 % over 16 h. Mechanism studies revealed the crucial roles of acid-base sites, reactive oxygen species, and metal valence states in CB degradation. The bimetallic system promotes the redox cycling between Cu(II)/Cu(I) and Mn(IV)/Mn(III), enabling continuous regeneration of active species. This work provides new insights for designing highly active and chlorine-tolerant catalysts for low-temperature purification of chlorine-containing VOCs.

Background: Influenza A virus is an acute respiratory virus that spreads quickly, affects a broad range of populations, and can lead to many complications and mortality.ArtemisiaL. species are widely used in traditional medicine, but their antiviral potential against H1N1 remains uncertain.Methodology: Network pharmacology and molecular docking were used to computationally explore their potential function in this domain, and to investigate how their invasion mechanisms and adsorption occur. UPLC-MS/MS analysis identified the main components of the extracts. The anti-H1N1 mechanism ofArtemisiaL. extracts was studied in vitro.Results: Network pharmacology identified 95 key targets betweenArtemisiaL. and IAV, with quercetin and luteolin as core active compounds. Molecular docking predicted strong binding affinities between these compounds and influenza virus proteins. UPLC-MS/MS analysis identified 75, 100, and 64 chemical components inACBE,AALE, andACTE, respectively, mainly flavonoids and terpenoids.ArtemisiaL. extracts exhibited both preventive and therapeutic effects against H1N1, reducing progeny virus NP mRNA and protein levels. In vitro experiments showed that higher concentrations of the extracts prevent virus attachment to MDCK cells by denaturing the HA protein. NA plays an essential role in progeny virus release. We found that a high concentration of ACTE can inhibit NA up to 85%, and ACBE showed a low inhibitory effect on NA.Conclusions: In terms of therapeutic effects,ArtemisiaL. extracts can regulate intracellular inflammatory factors via the TLR4/NF-κB/MyD88 signaling pathways and reduce the expression of IL-1β, IL-6, TNF-α, TLR4, NF-κB, p65, and MyD88 at the mRNA level, thereby inhibiting H1N1 virus replication. These results suggest that bioactive components inArtemisiaL. extracts may inhibit H1N1, potentially leading to the development of natural-product-based anti-influenza agents.

In recent years, there have been many significant breakthroughs in the research of potassium sodium niobate (KNN) based piezoelectric ceramics, positioning them as promising candidates for high-temperature piezoelectric device applications. To achieve synergistic optimization of high piezoelectric performance and high Curie temperature, the composition was designed to lie within the orthorhombic-tetragonal (O-T) phase coexistence region at room temperature by regulating the K/Na ratio, while the overall lattice stability was preserved. Our results show that the 0.96(KₓNa 1-x )(Nb 0.98 Sb 0.02 )O 3 -0.04Bi 0.5 Li 0.5 HfO 3 ceramic at x = 0.48 exhibits a high inverse piezoelectric constant of ~1383 pm/V and a strain of 1.32%, which are primarily attributed to the reduced polarization switching barrier enabled by the O-T phase coexistence at room temperature. Meanwhile, the local structural heterogeneity introduced by Sb 5+ and Hf 4+ doping further enhances the electrical strain response. Notably, the ceramic maintains a high Curie temperature of 276 °C, governed by the intrinsic lattice stability without significant compromise, confirming its great potential for high-temperature piezoelectric device applications.

Na3V2(PO4)3 has garnered significant attention as a promising cathode material for sodium-ion batteries due to its excellent ionic conductivity and robust structural stability. However, its further large-scale practical application has been hindered by its low electrical conductivity and poor interface kinetics. Therefore, it is reported in this study that the discharging/charging cycling and rate performance of Na3V2(PO4)3 cathodes are dramatically improved by the uniformly formed 3D carbon networks. Evidently, the Na3V2(PO4)3 cathode material prepared under the optimized conditions exhibited a relatively high initial capacity of 109.30 mAh/g at 0.1C with an initial Coulombic efficiency (ICE) of 99% and achieved an appreciable capacity of 99.42 mAh/g with a capacity retention of 96.39% after 400 cycles at 2C. Based on different characterizations and electrochemical performances, both the formation and sodium storage mechanism of Na3V2(PO4)3-based composite cathodes were initially concluded, which is significant and important for improving electrical conductivity and designing practical carbon-cladding strategies for Na-ion batteries.

Cr 3+ -activated phosphor has become the mainstream choice to obtain broadband near-infrared phosphor-converted light-emitting diodes (NIR pc-LED) for the applications of bio-imaging and component nondestructive detection. However, exploring efficient and stable Cr 3+ -activated NIR phosphors is still an important yet formidable challenge. Herein, a series of Na y K 3- y LiMg 4 (Si 2 O 5 ) 6 :Cr 3+ phosphors was synthesized, which exhibits a broadband emission spectrum spanning 650-1100 nm. Utilizing the innovative non-main lattice substitution strategy, the internal quantum efficiency (IQE) of Cr 3+ was enhanced from 21% to 80%, and thermal stability was also improved from 42% to 70%@150 °C. Based on the first-principles theory calculation, the IQE and thermal stability improvement are attributed to the strengthened local structure stability around Cr 3+ caused by the introducing of Na + . Finally, a NIR pc-LED device was packaged by combining the optimized Na 3 LiMg 4 (Si 2 O 5 ) 6 :4%Cr 3+ phosphor with blue LED chip, which demonstrates potential applications in biological imaging and night vision systems.

Technological progress has promoted the development of ultra-wide near-infrared (NIR) luminescent materials as a new NIR light source. The ultra-wide near-infrared (NIR) emission in Na(Al,Ga) 11 O 17 :xCr 3+ (NAGO:xCr 3+ ) phosphors is achieved by constructing unique Cr 3+ -Cr 3+ ion pair confined structure. The Cr 3+ -Cr 3+ ion pairs can be observed at a low concentration of Cr 3+ ions(x = 0.04), the increase of Ga 3+ ion would promote the formation of Cr 3+ -Cr 3+ ion pairs, thereby effectively enhancing the energy migration process from high-energy Cr 3+ ions to low-energy Cr 3+ ones. Herein, the full width at half maximum can be finely adjusted in a wide range from 17 to 223 nm, while the emission peaks can shift from 704 to 860 nm. NAGO:xCr 3+ exhibits the longest-wavelength emission in the known Cr 3+ -doped galliates and aluminates phosphors. The study further reveals the inherent mechanism of affect on the photoluminescence properties for Cr 3+ -Cr 3+ ion pairs. The quantum efficiency of optimal NaAl 11 O 17 :0.004Cr 3+ (sharp emission) and NaGa 11 O 17 :0.02Cr 3+ (ultra-wide emission) samples reaches 87.6% and 46.6% with high thermal stability (84.47% and 67.52%@150 °C), respectively. The comprehensive properties are excellent among known phosphors with similar property. Multifunctional applications of NAGO:xCr 3+ in agricultural production, quality inspection, and imaging fields are also demonstrated.

Carbonaceous materials , such as hard carbon and porous carbon , have gained great attentions as the anode materials for Na-ion batteries (NIBs). However, their defects and disordered structure cause the low initial coulombic efficiency (ICE), high-potential slope region and small charge capacity below 0.5 V. Herein, a structurally stable MOF contained 1,3,5-triazine-2,4,6-triamine moieties, belonging to the tetragonal space group I 4/m, is synthesized. On this basis, MOF-derived crystalline carbon with graphite-like crystal, instead of amorphous porous carbon, can be obtained due to slow pyrolysis of MOF framework along with timely and sufficient reassembly of the pyrolyzed carbon atoms into graphite-like crystal under graphite-induced condition. The graphite-like crystal has a geometrically similar unit cell to graphite crystal but with a magnification ratio of 1.25, yielding proportionally expanded d-spacing of (002) plane (4.2 Å), which enables the reversible Na + intercalation/de-intercalation. When applied in NIBs, it exhibits a very high ICE of 96.0% and reversible charge capacity of 356.2 mAh g −1 , reaching the advanced level of graphite applied in LIBs . More importantly, its charge capacity below 0.5 V can account for 90% of the total charge capacity, which is also the key parameter to effectively increase the energy density of full batteries.
