Currently, effective strategies to simultaneously restore both soft and hard periodontal tissues remain insufficient. To address this challenge, a multifunctional dual-layer microneedles (d-MNs) design is proposed to regenerate both periodontal soft and hard tissues in diabetic patients. The d-MNs substrate is composed of gelatin methacryloyl (GelMA) infused with nano-hydroxyapatite (nHA), which facilitates the differentiation of osteogenic cells into osteoblasts, thereby promoting alveolar bone regeneration. The tips of the d-MNs, on the other hand, are primarily made of hyaluronic acid (HA) combined with a magnesium-based metal-organic framework (Mg-MOF) loaded with glucose oxidase (GOX). This composition creates a hypoglycemic, angiogenic, and anti-inflammatory microenvironment, which supports soft tissue repair. When implanted at the site of periodontitis, the synergistic interaction between the d-MNs substrate and tips effectively promotes the regeneration of both soft and hard tissues, as demonstrated in diabetic rat models of periodontitis. These innovative d-MNs have the potential to revolutionize traditional approaches to treating diabetic periodontitis and can see broad application in dental clinics.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"23 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911967","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}

Driven by the pervasive and growing demands for miniaturization and energy efficiency in nanoelectronics, further reductions in the operating voltage of ferroelectric-based devices are dispensable and thus have received immense attentions. Recent remarkable advances in atomic-scale synthesis, cutting-edge characterizations, and multiscale theoretical calculations of ferroelectrics have gained unprecedented insights into the manipulation of emergent functionalities in multiple length scales, which helps the discovery of nontrivial polar structures and designs of device architectures toward the promise of ultralow-power consumption. Here, state-of-the-art strategies for reducing operating voltage in ferroelectric materials and devices are reviewed. This article starts with a brief introduction and major achievements in ferroelectrics, and expounds on the techniques to probe the polarization-switching process. Moreover, this article focuses predominantly on recent advancements in achieving low operating voltages through various prevalent strategies such as thickness scaling, defect engineering, chemical doping, surface and interfacial design, strain engineering. Finally, perspectives with scientific and technical challenges are discussed, aiming to facilitate the energy-efficient applications of ferroelectric materials and devices in future information technologies.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"68 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911756","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}

Herein, drawn inspiration from a spontaneous hydrazine‒H2O galvanic cell configured on a low-valence Ru single atoms-loaded Mo2C electrode (RuSA/v-Mo2C), an alternative H2 energy solution utilizing self-powered electrochemical hydrazine splitting (N2H4 → 2H2 + N2) instead of the stereotyped electricity-consumed water splitting for green H2 production is proposed. This solution highlights a pH-decoupled hydrazine‒H2O primary battery with notable open-circuit voltage of 1.37 V and energy density up to 358 Wh gN2H4−1, which powerfully propels an alkaline hydrazine splitting cell, leading to bilateral H2 harvest with a remarkable rate of 18 mol h−1 m−2, i.e., 403.2 L h−1 m−2, setting a new record for the self-sustaining electricity-powered H2 production systems. The success of RuSA/v-Mo2C for this solution is further decoded by tandem theoretical and in situ spectroscopic studies, cross-verifying a Ru‒Mo dual-site synergy in streamlining the overall energy barriers, thereby enhancing the kinetics of electrode reactions.

However, how to facilely and rapidly fabricate electroluminescent pixels with both high pixels per inch (PPI) and high quantum efficiency has been a great challenge. Here, a one-step, mask-free, rapid laser writing strategy to fabricate ultra-high resolution perovskite quantum dots (PQDs) pixels is presented. It is found that the laser-induced reaction can convert PQDs into oxide, forming perovskite@oxide pixel arrays, replacing the complex etching and deposition processes previously used. Benefiting from the formation of the oxide layer, electrons transport can be effectively blocked in the non-emitting region, thus reducing the charge leakage in micro quantum dots light emitting diodes (Micro-QLED) arrays. Finally, red, green, blue Micro-QLEDs are achieved with PPIs ranging from 2000 to 5000 and the highest external quantum efficiency of 17.24%, 21%, and 6.6% respectively. These results are record-breaking in perovskite Micro-QLEDs, providing the strategy for active-matrix electroluminescent high-resolution pixel arrays for next-generation monochromatic displays.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"34 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911762","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}

Without sufficient protection, these undesired impacts would lead to critical mechanical instability even damage to flexible sensors, resulting in restricted measurement range and imprecise sensing. Thus, it is of significance, but still is a fresh challenge to enhance the mechanical stability and energy-absorption capacity of flexible sensors under impacts. Here, a multi-design strategy is proposed to construct an interpenetrating-phase cellulose-acetate composite (IPC2) architecture for flexible sensors in impact-intensive sensing applications. The external structure mimics bellows-morphology of beverage-straws that deform in programmed loading direction to enhance the mechanical stability, while the internal conductive core has a co-continuous interpenetrating-phase architecture that can efficiently absorb impact energy. Systematic numerical analysis and experimental tests demonstrate that IPC2 architecture presents excellent structural stability, cyclic performance and a unique combination of exceptional specific energy absorption (SEA = 2.66±1.2 kJ kg−1), low density (ρ = 720±10 kg m−3), electromechanical properties (GF≈39.6). Remarkably, the recovery behaviors in terms of shape and electrical signals show good repeatability and reliability. This study offers a new composite framework to exploit the potentialities of flexible sensors with protective functions and commercial values.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"39 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911962","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}

While p-type performance is as essential as n-type in CMOS technology, the development of high-performance p-type 2D materials has lagged behind their n-type counterparts. Here, high-performance p-type tellurium (Te) field-effect transistors (TeFETs) that undergo plasma treatment at low temperatures to enhance their electrical and optoelectrical properties are presented. Ar plasma-treated Te shows significantly improved crystallinity compared to untreated counterparts, confirmed by various characterization techniques. Plasma treatment shifts the Fermi level toward the valence band and induces subgap states near the valence band in the Te film. A valence band offset of 0.2 eV and 30.6% surface flattening are confirmed in plasma-treated TeFETs. The electrical performance of plasma-treated TeFETs exhibits a 20-fold increase in the Ion/Ioff ratio, from 1.2 × 104 to 2.7 × 104, and a 51% reduction in subthreshold swing, from 19.1 to 9.4 V per decade, compared to pristine devices. Stability and bias stress tests show resilience to degradation after plasma treatment. Notably, optoelectrical performance improves due to the trap-assisted photogating effect.

Ionic thermoelectric materials based on the thermogalvanic effect can generate stable voltage under low-temperature differences, but their low thermopower and poor contact interface with electrodes hinder practical use. In this study, strong chaotropic salts are utilized to modify the solvation shells of ions, increasing the thermopower of the p-type redox couple [Fe(CN)₆]3⁻/[Fe(CN)₆]⁴⁻ to 3.98 mV K−1. Additionally, Arrhenius acid is introduced to inhibit the deprotonation of the n-type redox couple Fe3⁺/Fe2⁺, enhancing the thermopower to −2.29 mV K−1. Liquid metal electrodes, with excellent deformability and hydrogen bonding with hydrogel surfaces, effectively reduce the resistance of thermocells. Thus, a pair of p-n thermocells achieve a voltage output of 118 mV and a current density of 4.5 A m−2, with a maximum power density of 0.11 W m−2 (ΔT = 5 K).

To tackle this challenge, a photothermal evaporator with a novel parallel two-water paths strategy is developed in this study. Unlike the conventional one-way water path, which generally leads to salt accumulation at the water supply end on the evaporation surfaces, thereby limiting the lifespan of the evaporator and compromising solar evaporation performance, here, with the second parallel water supply path, the ion diffusion and distribution within the solar evaporator is reconfigured and optimized. No salt accumulation occurs on either the evaporation surfaces or the water paths, eliminating the impact of salt crystallization on evaporation performance and enabling convenient salt collection. A high and stable evaporation rate of 3.09–3.26 kg m−2 h−1 is recorded over 84 h continuous evaporation of NaCl solution (3.5 wt.%) without salt accumulation on the evaporator, making it an ideal strategy for zero liquid discharge solar evaporation.","PeriodicalId":112,"journal":{"name":"Advanced Functional Materials","volume":"25 1","pages":""},"PeriodicalIF":19.0,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142911972","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}
