The weak van der Waals gap endows two dimensional transition metal dichalcogenides(2D TMDs)with the potential to realize guest intercalation and host exfoliation.Intriguingly,the liquid intercalation and exfoliation is a facile,low-cost,versatile and scalable strategy to modulate the structure and physiochemical property of TMDs via introducing foreign species into interlayer.In this review,firstly,we briefly introduce the resultant hybrid superlattice and disperse nanosheets with tailored properties fabricated via liquid intercalation and exfoliation.Subsequently,we systematically analyze the intercalation phenomenon and limitations of various intercalants in chemical or electrochemical methods.Afterwards,we intensely discuss diverse functionalities of resultant materials,focusing on their potential applications in energy conversion,energy storage,water purification,electronics,thermoelectrics and superconductor.Finally,we highlight the challenges and outlooks for precise and mass production of 2D TMDs-based materials via liquid intercalation and exfoliation.This review enriches the overview of liquid intercalation and exfoliation strategy,and paves the path for relevant high-performance devices.

Injectability empowers conductive hydrogels to transcend traditional limitations,unlocking a realm of possibilities for innovative medical,wearable,and therapeutic applications that can significantly enhance patient care and quality of life.Here,we report an injectable,self-healable,and reusable hydrogel obtained by mixing the concentrated poly(3,4-ethylenedioxythiophene)doped with polystyrene sulfonate(PEDOT:PSS)suspension(~2 wt.%solid content),polyvinyl alcohol(PVA),and borax.Leveraging the presence of reversible borax/hydroxyl bonds and multiple hydrogen bonds,this PEDOT:PSS/PVA hydrogel exhibits notable shear-thinning behavior and self-healing capabilities,enabling it to be injected as a gel fiber from a syringe.As-prepared injectable hydrogel also demonstrates an ultra-low modulus(~2.5 MPa),reduced on-skin impedance(~45%of commercial electrodes),and high signal-to-noise ratio(SNR)(~15-22 dB)in recording of electrocardiography(ECG),electromyography(EMG),and electroencephalogram(EEG)signals.Furthermore,the injectable hydrogels can be remolded and reinjected as the reusable electrodes,maintaining nearly identical electrophysiological recording capabilities and brain-computer interface(BCI)performance compared to commercial wet electrodes.With their straightforward fabrication,excellent material properties and electronic performance,ease of cleaning,and remarkable reusability,our injectable PEDOT:PSS/PVA hydrogels hold promise for advancements in BCI based electronics and wearable bioelectronics.

Tumor hypoxia severely limits the therapeutic efficacy of photodynamic therapy(PDT) for solid tumors,which is highly dependent on tissue oxygen concentration.In this study,we developed a platinum(Ⅱ)-acetylide-based metallacycle compound bearing six 1,4-dimethylnaphthalenes(DMN) groups,and controlled the photodynamic and photothermal effects of the compound by adjusting the power of 730 nm laser to achieve reversible sensitization,storage and release of 1~O_(2) within a single molecule.The compound formed nanoparticles by self-assembly and exhibited good water solubility and biocompatibility.Under laser irradiation,the strong spin-orbit coupling of platinum atoms in the metallacycle facilitated 1~O_(2) generation.The produced 1~O_(2) was captured by the DMN carriers and transported into the hypoxic tumor,where 1~O_(2) release was triggered owing to the good photothermal effect of the extended conjugation of the metallacycle.During therapy,the metallacycle serving as a photosensitizer,1~O_(2) carrier,and photothermal reagent,achieved the synergistic therapy of PDT/PTT,demonstrating the versatility of the metallacycle.This study proposes a new strategy to develop phototherapy agents that are suitable for hypoxic tumors.

Potassium-ion batteries(PIBs)represent one of the most promising alternatives to lithium-ion batteries(LIBs),owing to their exceptional attributes such as high voltages,potent power capabilities,and cost-effectiveness.Nonetheless,challenges arise from the sluggish kinetics and significant volume expansion observed during the insertion/extraction of large-radii potassium ions,leading to subpar rate performance and considerable capacity degradation in potassium-ion batteries.Consequently,it becomes imperative to explore advanced anode materials exhibiting high electrochemical activity and robust structural stability.In this regard,the present review focuses on recent progress in metal-organic compounds(MOCs)as anode materials for potassium-ion batteries,systematically discussing their outstanding merits from the perspective of metal speciation.Additionally,the principal mechanism of K ion storage within relevant MOCs is presented.Furthermore,a comprehensive summary of existing drawbacks that hinder the broader application of MOCs-based materials is provided,along with proposed guidelines and strategies for addressing the inferior performance characteristics.This review serves to illuminate the development of MOCs-based anode materials for potassium-ion batteries and offers a valuable reference for future research endeavors.

Deformable catalytic material with excellent flexible structure is a new type of catalyst that has been applied in various chemical reactions,especially electrocatalytic hydrogen evolution reaction(HER).In recent years,deformable catalysts for HER have made great progress and would become a research hotspot.The catalytic activities of deformable catalysts could be adjustable by the strain engineering and surface reconfiguration.The surface curvature of flexible catalytic materials is closely related to the electrocatalytic HER properties.Here,firstly,we systematically summarized self-adaptive catalytic performance of deformable catalysts and various micro–nanostructures evolution in catalytic HER process.Secondly,a series of strategies to design highly active catalysts based on the mechanical flexibility of lowdimensional nanomaterials were summarized.Last but not least,we presented the challenges and prospects of the study of flexible and deformable micro–nanostructures of electrocatalysts,which would further deepen the understanding of catalytic mechanisms of deformable HER catalyst.

Aqueous zinc(Zn)ion batteries(AZIBs)are regarded as one of the promising candidates for next-generation electrochemical energy storage systems due to their low cost,high safety,and environmental friendliness.However,the commercialization of AZIBs has been severely restricted by the growth of dendrite at the Zn metal anode.Tailoring the planar-structured Zn anodes into threedimensional(3D)structures has proven to be an effective way to modulate the plating/stripping behavior of Zn anodes,resulting in the suppression of dendrite formation.This review provides an up-to-date review of 3D structured Zn metal anodes,including working principles,design,current status,and future prospects.We aim to give the readers a comprehensive understanding of 3D-structured Zn anodes and their effective usage to enhance AZIB performance.

Photodynamic therapy(PDT)is an effective treatment method for tumors.But the specifically accumulated of photosensitizer was very difficult in the tumor site,which greatly limited the efficacy of PDT.Here,mitochondria-targeted Janus mesoporous nanoplatform(JPMO-Pt-CTPP-ZnPc)for PDT was prepared,the nanoplatform has uniform size(275 nm)and good dispersion and biocompatibility.The confocal laser scanning microscopy(CLSM)revealed the signal of ZnPc of JPMO-Pt-CTPP-ZnPc were higher than JPMO-Pt-ZnPc in tumor cells,and flow cytometry results showed the cell uptake efficiency of JPMO-Pt-CTPP-ZnPc was 2.5-fold higher than that of JPMO-Pt-ZnPc.This revealed the modification of CTPP significantly improves the targeting ability of the nanoplatform.In vitro anti-tumor experiment showed the JPMO-Pt-CTPP-ZnPc significantly inhibited the growth of tumor cells upon the irradiation of low-power laser,and the survival rate of cells incubated with 60μg/mL JPMO-Pt-CTPP-ZnPc was only 3%.Simultaneously,compared with JPMO-Pt-ZnPc(not modified with mitochondria targeting molecules CTPP),the PDT efficacy of JPMO-Pt-CTPP-ZnPc was significantly better,as it has targeted mitochondria in cells.
