Here we propose a distinctive structural prototype of displacive FEs from an experimentally prepared In2Te5 compound, and find ferroelectricity can be triggered in the In2Te5 monolayer by applying tensile strain to soften the transverse optical modes localized at the planar-coordinated Te chains, where the shielding effect of wrinkled spacer chains formed by vertex-sharing In-Te tetragons leads to scale-free ferroelectricity with independently switchable FE polarizations. Furthermore, elemental substitutions with experimental feasibility enable us to produce 2D scale-free FEs of this prototype by demonstrating the stability of M2S5 (M = Al, Ga, In, Tl) and M2Se5 (M = In, Tl) with intrinsic ferroelectricity. The FE polarizations stem from tailoring the chemical bonds of the chalcogen elements by using tensile strain or ionic radius differences, which gives the definite feature of elemental ferroelectricity but contained within compounds. We believe the M2X5 monolayers with the distinctive structural prototype represent unique elemental ferroelectric compounds and will promote development of 2D scale-free ferroelectricity once realized in experiments.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144315602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Perception of food is an important component of human sensations closely related to healthcare and overall quality of life, which, however, is an underrepresented area in current VR/AR technologies. This review summarizes recent progress in simulating chemical and physical sensations for enhancing eating experiences by utilizing emerging wearable electronics. We start with a brief overview of the key sensory components that shape eating-related perceptions, including the widely studied physical cues (auditory, visual, tactile) as well as the often-overlooked chemical senses (olfactory, gustatory). Then, we review prior work on eating experience-related HMIs, organizing them according to two main categories: sensors used for information capture and actuators used for the simulation of sensations. In the following section, we further discuss the integration of these wearable electronics with hardware and software to build Internet-of-Things and advanced HMIs for human-in-the-loop interactions. The final section summarizes remaining challenges and provides an outlook on the development of eating experience related VR/AR technologies for various applications, with the goal of providing references and guidelines for future research efforts in this underexplored yet thriving field.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144315600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, the development of advanced EMI shielding materials capable of ultra-broadband compatibility, multifunctional and wearability has emerged as an essential and urgent task. Conductive filler-integrated hydrogels (CFHs) demonstrate remarkable application prospects as an innovative multifunctional EMI shielding material, due to their tunable electrical conductivity, excellent flexibility, self-healing ability, and environmental and biological friendliness. This review commences by delving into the EMI shielding mechanisms of CFHs, exploring the crucial factors that affect their shielding performance, including water molecules, porous structures, and the type of conductive fillers. Subsequently, the fabrication methods and comprehensive performances of CFHs incorporating various conductive fillers, as well as different aerogels derived from CFHs, are systematically summarized. Finally, the potential challenges hindering the practical application of CFHs and their derived aerogels are discussed, and perspectives on how to overcome these challenges in future research are provided, thereby offering insightful guidance for the design of novel CFHs and aerogels for efficient and multifunctional EMI shielding.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although frequently used H2O2 reduction catalysts can avoid influence from many interferences, their inability to simultaneously prevent the oxygen reduction reaction (ORR) during H2O2 detection presents a significant limitation. In this study, a selective sensing platform based on noble metal/tin oxide (NM/SnO2) was fabricated by depositing an ultra-thin passivation layer of SnO2 onto noble metal catalysts using atomic layer deposition (ALD) technology. The amorphous SnO2 layer effectively inhibits O2 diffusion to the metal/oxide interface, endowing NM/SnO2 with remarkable tolerance to the ORR and enhancing its selectivity and performance in the electrochemical detection of H2O2. Based on this sensing platform, a series of bioassay systems were developed that can accurately detect multiple biomarkers, including glucose, lactate, and choline. This work provides a straightforward and controllable strategy for fabricating ORR-tolerant H2O2 reduction catalysts, with promising applications in electroanalysis and clinical diagnosis.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A common strategy involves incorporating high-thermal-conductivity fillers such as graphene and boron nitride nanosheets (BNNS). However, practical enhancements often fall short of theoretical predictions due to interfacial thermal resistance (RKapitza). Here, we address this challenge by engineering the hydrogen bond density (HBD) at the filler-matrix interface. By grafting 3,4-dihydroxyphenylalanine (DOPA) onto polyvinyl alcohol (PVA), we synthesized PVA-DX matrices (X = 0, 8, 12, 17, 24) with tunable HBDs. Incorporation of BNNS into these matrices revealed that higher interfacial HBD significantly reduces RKapitza, thereby enhancing the composite's thermal conductivity (κc). We achieved an exceptionally low RKapitza of 0.60 × 10-8 m2 K W-1, corresponding to a filler effectiveness (κc/∅f) of 120 W m-1 K-1. Notably, at a BNNS loading of 70 vol%, increasing the interfacial HBD to 2.14 mmol cm-3 achieves a κc of 51.01 W m-1 K-1, which is 1.45 times higher than the 35.29 W m-1 K-1 attained at an HBD of 0.5 mmol cm-3. This study underscores the critical role of interfacial hydrogen bonding in optimizing thermal transport and provides a robust framework for designing high-performance polymer composites for advanced thermal management applications.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Generative artificial intelligence approaches have recently been applied to overcome this limitation and explore unknown stoichiometries and structures, but efficiently generating candidates that satisfy strict stability criteria remains challenging. Here we introduce a physics-informed hierarchical generative framework that leverages symmetry-aware crystallographic principles to systematically explore molecular configurations, lattice parameters, and bonding environments. Our approach integrates empirical physical constraints and reinforcement learning utilizing a hierarchical state representation to generate chemically valid and structurally stable candidates. We propose symmetry-aware hierarchical architecture for flow-based traversal with density (SHAFT-density) that ensures efficient exploration of the material search space, prioritizing low formation energy, molecular packing optimized for stability and conductivity, and enhanced electrochemical properties. We discovered new binary and ternary metastable phases, of which we find highly conductive LiBr, LiCl, Li2IBr, and Li3CBr2. These materials can either function as solid-state electrolyte materials or be part of solid-state electrolyte mixtures.

Here, we demonstrate high-performance electronic synapses based on a high-throughput ferroelectric BaTiO3 (BTO) thin film. Two-terminal ferroelectric memristors are fabricated on a thickness-gradient BTO film with thickness ranging from 1 to 30 unit cells (UC), and intrinsic ferroelectricity is revealed in regions with thickness >5 UC. Notably, three typical resistive switching behaviors of resistor, FTJ, and FD occur sequentially with increasing BTO thickness, allowing these three basic electronic components to be integrated. High-performance FTJ synapses with adaptive conductance compensation from resistor and FD components are proposed based on an on-chip integration configuration. This approach improves the accuracy of handwritten digit recognition using artificial neural networks (ANNs) from 91.3% to 95.7%.
