These interfaces provide MoS₂ with undisturbed, atomically smooth electrical contacts, and enable efficient gate control via electric double layers. Benefiting from the inherent softness of liquids and their damage-free processing, Fermi level pinning is significantly mitigated by the liquid metal, achieving a pinning factor |s| = 0.7. Meanwhile, the ionic liquid enables a subthreshold swing of 60.7 mV dec-1, approaching the theoretical thermal limit. Furthermore, our flexible transistors demonstrate multifunctionality as enhanced logic gates, low-voltage inverters, and ultra-high-linearity synaptic devices.

Yet, harnessing chemo-mechanical signal conversions in synthetic systems remains a key challenge in energy-dissipative materials design. While droplets can move and interact with their environment reminiscent of active biological matter, chemo-mechanical interactions are limited by the translation of chemical changes into extensive force variations required on small timescales. Droplets naturally adopt spherical shapes to minimize surface-energy and restructuring liquids into non-equilibrium geometries requires mechanisms beyond current stimuli-responsive surfactant systems, which lack the force-amplifying mechanisms needed for transient liquid structuring. Here, a spring-like charging and latch-controlled release mechanism is introduced for actuating droplets. This is based on reversible, light-induced crystal-to-coacervate phase transitions of photo-responsive surfactant assemblies, namely between anionic sodium dodecylsulfate and cationic azobenzene-based surfactants. During phase-transition, reversible partitioning of the surfactants into the oil or aqueous phases of the emulsion transiently induce rapid changes in interfacial tensions, which are up to 900 times greater than those observed for conventional stimuli-responsive surfactant systems. The insights into this novel chemo-mechanical transduction mechanism provide new control over purely liquid systems, paving the way for programmable, hierarchically structured, all-liquid matter acting with physicality.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"54 1","pages":"e2506100"},"PeriodicalIF":29.4,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144488202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the electrolyte instability leading to inferior rate performance and short lifespan remains to be addressed. In this study, a new non-concentrated gradient-solvation electrolyte by solvent polarity discrepancy is developed. A highly donor-capable ether forms the Li⁺-solvated core through strong ion-dipole interactions, while a weakly donating carbonate creates the shell structure. Such a gradient-solvation structure enables the electrolyte with a high oxidation voltage (4.6 V vs. Li/Li+) and rapid Li+-desolvated kinetic. Consequently, the electrolyte facilitates the LiNi0.8Co0.1Mn0.1O2 (NCM811)||Li cells to attain a specific capacity of 165.8 mAh g-1 at 5C, alongside 1000 stable cycles at 1C charge/3C discharge with 66% capacity retention. Even under lean conditions (N/P = 1.5, electrolyte: 20 µL), NCM811||Li cell still maintains 97.5% capacity retention over 100 cycles.

This approach, however, suffers from critical issues of binding saturation for cfDNA and risk of re-exposure of the captured cfDNA. Herein, an inflammation-activatable nanoscavenger integrating both cfDNA capture and cleavage functions is constructed from dendrimer-templated, charge- and conformation-transformable polypeptides with Cyclen-Zn complexes conjugated on the backbone termini. At neutral pH, the polypeptides containing both cis-aconitic acid and guanidine side chains adopt negative charges and random-coiled conformation, thus featuring long blood circulation and high accumulation to the inflamed intestinal tissue. Inside the mildly acidic inflammatory microenvironment, the polypeptides transform to the positively charged α-helices due to removal of the cis-aconitic acid groups, thus enabling robust cfDNA capture through electrostatic attraction, salt bridging, and spatial confinement within the cavity between adjacent rod-like helices. Subsequently, the exposed Cyclen-Zn endows the nanoscavenger with DNase-like activity to cleave the captured cfDNA, allowing sustainable cfDNA capture and scavenging. In consequence, the nanoscavenger efficiently inhibits TLR9 activation and restores immune homeostasis in IBD mice. This study proposes an enlightened strategy for sustainable cfDNA scavenging, and it renders a promising modality for AIDs treatment.","PeriodicalId":114,"journal":{"name":"Advanced Materials","volume":"9 1","pages":"e2504557"},"PeriodicalIF":29.4,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144488197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through tailoring the -NH2 group numbers and pore sizes creates ingenious H2O sites, preserving CO2 adsorption space and enhancing CO2 adsorption interactions in 1D channels.

Consequently, it shows top-performing CO2 enrichment ability with easy regeneration in long-term separation experiments (over 100 cycles) under high-humidity (75% RH).

Moreover, NH4X (X = Cl, Br, I) etchants combined with small-molecule intercalants enabled the targeted synthesis of MXene-based heterostructures, such as Mo2CTx@MoS2 featuring ≈15 nm amorphous MoS2 surface layers. Notable, the Mo2CTx(Br) heterostructure exhibited outstanding electrochemical stability, delivering a capacity of 465.5 mAh g⁻¹ after 300 cycles at 1 A g⁻¹, and achieving high coulombic efficiency of 99.8% during lithium-ion battery cycling.

Herein, a Fukui function-guided molecular engineering approach is proposed to develop a gel electrolyte (HG-3TP) with higher Gibbs free energy of HER (ΔGHER). The reduced electrophilic Fukui function inhibits Zn electron extraction while participating in Zn2⁺ solvation to decrease free water activity. Simultaneously, attenuated nucleophilic Fukui function creates an inert barrier on Zn anodes, raising H⁺ desorption energy and lowering proton diffusion. These synergistic effects suppress the Volmer/Heyrovsky step, significantly increasing ΔGHER and inhibiting HER. Meanwhile, optimized interfacial energetics facilitate uniform Zn plating/stripping while maintaining cathode compatibility. As a result, Zn batteries with HG-3TP exhibit excellent long-term cycling stability, achieving 4,000 h in Zn||Zn symmetric cells and maintaining operation for 710 h at 60 °C, while demonstrating 83.5% capacity retention over 11 000 cycles in Zn||VO2 full cells.

While often attributed to sluggish ion transport, the underlying mechanisms and the quantitative link between thickness and performance remain unclear due to complex pore structures and nanoconfined ion dynamics. Here, using multilayered graphene membranes as a model system, modified Poisson-Nernst-Planck simulations with experiments are combined to reveal how electrosorbed ions reshape local electrical and chemical potentials, particularly as the surface-to-volume ratio increases with reduced pore size. It is shown that electrosorbed ions substantially influence the scaling behavior of capacitance across electrode thicknesses, causing marked deviations from classical transmission line models as pores approach nanometric dimensions. Despite the complexity introduced by nanoconfinement, introducing a correction factor enables capacitance-scan rate relationships to collapse into a unified curve across various electrode architectures, allowing computationally efficient design of high-performance fast-charging electrochemical and iontronic devices.
