Abstract ：
Delicate design high-efficiency sulfur electrocatalysts is crucial for suppressing the shuttle effect of soluble lithium polysulfides (LiPSs) and improving the electrochemical performance in lithium-sulfur (Li-S) electrochemistry. Herein, a self-supported hierarchical NiCo2Se4@Ni0.85Se/MoSe2 electrocatalyst with abundant heterointerfaces and anion vacancies that directly grows on carbon cloth is elaborately designed to accelerate the sulfur redox reaction kinetics effectively. Noteworthy, the abundant heterointerfaces coupling with anion vacancies greatly facilitate the electron transfer, strengthen the chemical adsorption, provide sufficient active sites, and enhance the catalytic activity. Additionally, the hierarchical hollow arrayed architecture can guide the Li2S deposition, relieve the volume expansion, and maintain the structural stability. Consequently, the Li-S batteries with CC@NiCo2Se4@Ni0.85Se/MoSe2 exhibit exceptional electrochemical performance and high sulfur utilization even under high sulfur loading. More importantly, the pouch cells are fabricated to demonstrate the potential for practical applications. Furthermore, the integration of experimental and computational studies confirms that the Ni0.85Se/MoSe2 heterostructure possesses stronger chemical adsorption and reduced energy barrier for LiPSs conversion than MoSe2. Interestingly, it is also discovered that the incorporation of Ni0.85Se promotes the in situ lithium ions intercalation in MoSe2, which is conductive to further performance enhancement. This study provides new inspiration for the hierarchical engineering of electrocatalysts toward high-performance Li-S batteries. © 2025 Wiley-VCH GmbH.

Abstract ：
2D materials exhibit unique properties for next-generation electronics and quantum devices. However, their sensitivity to temperature variations, particularly concerning cooling-induced strain, remains underexplored systematically. This study investigates the effects of cooling-induced strain on monolayer MoSe2 at cryogenic temperatures. It is emphasized that the mismatch in thermal expansion coefficients between the material and bulk substrate leads to significant external strain, which superimposes the internal strain of the material. By engineering the material-substrate 2D-bulk interface, the resulting strain conditions are characterized and reveal that substantial compressive strain induces new emission features linked to direct-to-indirect bandgap transition, as confirmed by photoluminescence and transient absorption spectroscopy studies. Finally, it is demonstrated that encapsulation with hexagonal boron nitride can mitigate the external strain by 2D-2D interfaces, achieving results similar to those of suspended samples. The findings address key challenges in quantifying and characterizing strain types across different 2D-bulk interfaces, distinguishing cooling-induced strain effects from other temperature-dependent phenomena, and designing strain-sensitive 2D material devices for extreme temperature conditions.

Abstract ：
The sluggish reaction kinetics and formidable shuttle effect of soluble lithium polysulfides (LiPSs) are thorny problems for the future industrialization of lithium-sulfur (Li-S) batteries. Therefore, exploring efficient electrocatalysts to capture LiPSs and accelerate their conversion is highly desirable yet tremendously challenging. Herein, a high-efficiency Bi/Bi2O3/VMoN@rGO electrocatalyst with multifunctional active sites and multilevel heterointerfaces is elaborately designed for Li-S batteries. Noteworthy, the multilevel heterointerfaces can greatly modulate the electron distribution, facilitate the charge transfer, optimize the chemical absorption, and enhance the intrinsic activity, while rGO contributes to high electrical conductivity, sufficient active sites, and robust structural stability. Thanks to the synergy of different components, Li-S batteries employing the Bi/Bi2O3/VMoN@rGO functional separators exhibit impressive electrochemical performance and high sulfur utilization even under high sulfur loading. More importantly, it is discovered that Bi and Bi2O3 experience an electrochemical phase evolution to generate Bi2S3 with amorphous and crystalline phases, thereby bringing in unexpected performance enhancement. Furthermore, experimental results and theoretical calculations authenticate that a reduced Li2S decomposition energy barrier is achieved after the in situ electrochemical reconstruction. This work not only provides new mechanistic insights into developing high-efficiency sulfur electrocatalysts but also sheds light on regulating the catalytic activity via self-reconstruction.

Abstract ：
The ability to rapidly produce large single crystals is crucial for advancing the applications of covalent organic frameworks (COFs). Although the modulation strategy provides a straightforward method for growing high-quality single crystals, the slow crystallization process of COFs often limits their practical use. In this study, we combined the principles of crystallization thermodynamics and kinetics with the modulation strategy to develop a binary solvent-supersaturation method, enabling the growth of single-crystal COFs in a significantly shorter time. By systematically investigating the crystal-growth kinetics across different solvent ratios, we established a diffusion-reaction growth model, highlighting the essential role of supersaturation in controlling COF crystal growth. Especially, under this crystallization guidance, elegant single crystals of COFs built with heteroatom or other functionality can also facilely obtained, which spontaneously validate the universality of the protocol. Importantly, the resulting single-crystal COFs, characterized by high structural symmetry, exhibited notable second harmonic generation (SHG) activity, which could open new avenues for future research in this field.

Abstract ：
Sodium ion hybrid capacitors (SIHCs) are garnering substantial interest in the energy storage field due to their unique capability to integrate high energy density and power density with the economic advantages of abundant sodium resources. However, the kinetic mismatch between battery-type anodes and capacitor-type cathodes presents a significant obstacle, severely limiting the performance potential of high-performance SIHCs. Herein, we report the development of a favorable pseudocapacitive Na+ storage nanohybrid, featuring VC nanodots confined within an N-doped carbon nanofiber network (VC@N-CNFs), which has been successfully applied to SIHCs. The integration of VC nanodots with a conductive carbon fiber framework significantly enhances electron transport and provides ample interface between the electrolyte and VC active material, thereby effectively improving the reaction kinetics of the anode. Consequently, the VC@N-CNFs demonstrate exceptional sodium storage capability, achieving a high capacity of 160.2 mA h g-1 at 1 A g-1 after 2000 cycles. Thanks to the favorable kinetic matching between the anode and cathode, the assembled SIHCs exhibit high energy and power densities of 97.8 W h kg-1 and 4118.3 W kg-1, respectively, alongside remarkable cycling performance, retaining 73.5% of their capacity after 6000 cycles.

Abstract ：
The rapid advancement of neuromorphic computing and machine vision drives the need for optoelectronic memories that mimic neural and visual systems, integrating optical sensing, data storage, and processing. Traditional fabrication methods are often complex, multistep processes that struggle to achieve lightweight, scalable, and flexible designs. This limitation highlights the need for alternative approaches like printing technologies to enable flexible optoelectronic memory development. Here, a novel approach is presented to print optoelectronic memories using graphene (Gr)/WS2 nanostructured composite ink. This composite ink utilizes Gr nanosheets as conductive channels and defect sites in WS2 as charge capture centers, forming local heterojunctions that enable efficient photoelectric storage. Two types of Gr/WS2 composite inks are developed, tested, and compared with pure Gr ink. The findings reveal that the Gr/WS2 nanocomposite ink with enhanced edge states exhibits superior memory performance. Devices print using this ink demonstrated the ability to store visual information in both single-pulse and multi-pulse modes, reflecting potential applications in retina-inspired visual persistence and neuromorphic computing. This work highlights the promise of printed 2D material-based optoelectronic memories for advancing scalable, low-cost, and flexible electronic devices.

Abstract ：
The development of appropriate cathode materials with stable structures and fast diffusion kinetics of zinc ions is crucial for aqueous zinc-ion batteries (AZIBs) but remains significantly challenging. Herein, the design and synthesis of defect-rich and prismatic-shaped nanohybrids composed of vanadium oxynitride nanoparticles confined in the porous nitrogen-doped carbon framework (VNxOy@NC) are reported. Its unique structural advantages, including enriched defect sites that effectively enhance electrical conductivity, accelerate charge transfer kinetics, and improve structural stability. Additionally, the introduction of structural defects in VNxOy@NC increases the adsorption energy and reduces the hopping barrier of Zn ion, as evidenced by density functional theory (DFT) calculations. The H+ and Zn2+ co-insertion/extraction mechanism was systematically validated by ex-situ X-ray diffraction and ex-situ X-ray photoelectron spectroscopy tests. Consequently, the VNxOy@NC//Zn batteries exhibit an exceptional capacity of 570.9 mAhg-1 at 0.2 Ag-1, a superior rate capability of 446.7 mAhg-1 at 20 Ag-1, and long cycling life. Furthermore, the corresponding quasi-solid-state battery delivers an ultra-high energy density of 271.9 Whkg-1, demonstrating potential for practical applications. This work presents an effective structural and defect engineering strategy for designing advanced electrode materials with promising applications in AZIBs.

Abstract ：
van der Waals (vdW) superlattices, comprising different 2D materials aligned alternately by weak interlayer interactions, offer versatile structures for the fabrication of novel semiconductor devices. Despite their potential, the precise control of optoelectronic properties with interlayer interactions remains challenging. Here, we investigate the discrepancies between the SnS/TiS2 superlattice (SnTiS3) and its subsystems by comprehensive characterization and DFT calculations. The disappearance of certain Raman modes suggests that the interactions alter the SnS subsystem structure. Specifically, such structural changes transform the band structure from indirect to direct band gap, causing a strong PL emission (similar to 2.18 eV) in SnTiS3. In addition, the modulation of the optoelectronic properties ultimately leads to the unique phenomenon of thermally activated photoluminescence. This phenomenon is attributed to the inhibition of charge transfer induced by tunable intralayer strains. Our findings extend the understanding of the mechanism of interlayer interactions in van der Waals superlattices and provide insights into the design of high-temperature optoelectronic devices.

Abstract ：
Amorphous transition metal oxides have recently received particular research interests in electrochemical energy storage. However, there is still a lack of direct comparisons between amorphous materials and their crystalline counterparts. Here, we demonstrate the rational synthesis of crystalline and amorphous Fe2O3 nanocubes uniformly grown on carbon nanofibers (denoted as CNFs@C-Fe2O3 and CNFs@A-Fe2O3, respectively) for lithiumion batteries (LIBs) and lithium-sulfur batteries (LSBs). In such a structure, the Fe2O3 nanocubes possess strong interfacial bonding with CNFs, which can ensure rapid electron transportation. Besides, these Fe2O3 nanocubes are highly porous, which can effectively alleviate the volume change, enlarge the surface area, increase active sites and facilitate ion diffusion. When employed as freestanding anode for LIBs, the CNFs@C-Fe2O3 electrode delivers much improved lithium ion storage performance compared to that of CNFs@A-Fe2O3. When evaluated as interlayers for LSBs, instead, the batteries with CNFs@A-Fe2O3 exhibit better rate performance cycling stability than that of with CNFs@C-Fe2O3. Moreover, theoretical calculations elucidate the amorphous Fe2O3 has stronger adsorption ability toward the soluble lithium polysulfides. This work would provide new insights into the reasonably development of crystalline and amorphous transition metal oxides toward electrochemical energy storage.

Abstract ：
Catalytic conversion of polysulfides has been regarded as an effective strategy to suppress the shuttle effect in lithium-sulfur (Li-S) batteries by accelerating the conversion of lithium polysulfides (LiPSs). However, the rational design of high-performance sulfur electrocatalysts still remains a big challenge. In this work, we develop a facile approach to synthesize a grain-boundary-rich cobalt selenide hollow multi-shelled structure (denoted as GB-CoSe HoMS) to serve as a high-efficiency electrocatalyst for Li-S batteries. Such a unique structural design could physically inhibit the diffusion of polysulfide intermediates and effectively accommodate the large volume expansion. Besides, the GB-CoSe HoMS possesses strong chemical adsorption towards LiPSs and superior catalytic activity to accelerate the conversion reaction kinetics, thereby suppressing the shuttle effect of LiPSs and enhancing the sulfur utilization. Owing to the multifarious advantages, the assembled Li-S batteries with GB-CoSe HoMS modified polypropylene separators display a high initial discharge capacity of 1393.3 mA h g-1 at 0.1C, superior rate performance (660.9 mA h g-1 at 3C), and good long-term cycle stability with a low capacity decay rate of 0.046% per cycle after 1000 cycles at 1C. More significantly, even with a high sulfur loading of 5.5 mg cm-2 and lean electrolyte (E/S approximate to 8.0 mu L mg-1), the battery still harvests a high discharge capacity of 977.8 mA h g-1 after 40 cycles at 0.2C, suggesting its great potential for practical applications. The present work demonstrates the importance of engineering the morphology and grain boundary in developing high-performance electrocatalysts for Li-S batteries. A unique grain-boundary-rich cobalt selenide hollow multi-shelled structure (GB-CoSe HoMS) has been rationally designed and synthesized as a high-efficiency electrocatalyst to adsorb and convert the polysulfides for lithium-sulfur batteries.
