To date, more than 1500 nanomaterials have been identified with enzyme-like activities, some demonstrating catalytic performances that match or even exceed those of natural enzymes. Despite this progress, key challenges remain, including poorly understood catalytic mechanisms, ambiguous structure-activity relationships, and a heavy dependence on nonspecific surface sites, all of which limit the efficiency, selectivity, and broader application of nanozymes. To address these limitations, researchers are turning to nature for inspiration, seeking to reconstruct enzyme active centers at the atomic scale and establish innovative design principles. This review examines the catalytic mechanisms and structural characteristics of natural enzymes, integrating machine learning approaches to investigate nanozyme kinetics, transition state stabilization, electron/proton transfer, and cooperative effects. It highlights bioinspired strategies such as three-dimensional structure design, cofactor incorporation, and artificial organelle systems. Furthermore, the review explores rational nanozyme design using activity descriptors and predictive modeling. Finally, it outlines the transformative potential of artificial intelligence and multiscale simulations in optimizing nanozyme performance, offering a theoretical foundation for the development of next-generation intelligent nanozymes.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144148724","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}

The prevailing paradigm in this area primarily focuses on valleys associated with ferromagnetic and ferroelectric properties. In this study, we go beyond the existing paradigm to propose a novel mechanism, termed ferroelastic valleytronics. The inversion of the valley index is achieved through transformations of the ferroelastic state. Using first-principles calculations and model analysis, we validate this concept in Pd4X3Te3, a material with intrinsic valley polarization that is ferroelastically controllable. Beyond its intrinsic valley polarization and ferroelasticity, Pd4X3Te3 exhibits a range of intriguing physical phenomena, including anisotropic carrier mobility at valleys, ferroelastic-correlated Hall coefficients, and valley-contrasted selectivity for linearly polarized light. Furthermore, non-adiabatic molecular dynamics (NAMD) simulations reveal the dynamics of intervalley carrier transfer and recombination in Pd4X3Te3. Our results indicate that hole transfer between valleys occurs more rapidly than electron transfer and that intervalley carrier recombination takes place on the nanosecond timescale. This theoretical research not only provides a promising approach to control valley polarization but also advances the emerging field of valleytronics.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144148727","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}

However, achieving precise control over their structures and compositions to enhance solution processability and film properties remains a significant challenge. This study introduces a novel ligand-regulation strategy for modularly assembling In-Ti-oxo clusters and represents the pioneering application of In-Ti-oxo clusters in nanolithography. Specifically, we explore the indium-based flexible trifurcate InL3 as a metalloligand (L = salicylate derivatives) to stabilize isomeric In4Ti12-cores with varying spherical shells: InOC-20V, InOC-21V, InOC-22V and InOC-23H. These isomers, in turn, induce markedly distinct solution processabilities. InOC-20V to InOC-22V feature vertically connected Ti6In2-SBUs, resulting in superior solubility compared to InOC-23H, which has parallel-connected Ti6In2-SBUs. In addition, the organic periphery is critical for film formation, and only InOC-20V, decorated with salicylate groups, produces high-quality films via spin-coating with 50 nm resolution patterns for lithography. To gain insight into the exposure mechanisms, a combination of DFT calculations, TGA-MS, XPS, and AFM-IR was used, indicating that the decarboxylation of the ligands significantly contributes to the solubility-switching behaviors necessary for lithography. These findings offer generalizable synthetic methods to expand the In-Ti-oxo cluster structural chemistry and highlight the efficacy of tailored structural modulation of cluster materials in enhancing solution processability and lithography performance, providing valuable insights for future material design and applications.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144148728","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}

Current research focuses on passive driving mechanisms through structural design or surface design/enhancement. Among these, passive regulation of fluid transport through surface wettability gradient differences is a hot topic. This study constructed patterned surfaces through ordered/disordered combinations of hydrophilic/hydrophobic/superhydrophobic (wettability/hydrophobicity) properties and investigated fluid flow behavior. A \"Smart\" valve design was proposed, which utilizes changes in contact angle hysteresis force (Fh) caused by interfacial wettability differences to achieve micro flow-velocity regulation. The results showed that when water flowed through pattern I, the flow rate experienced a two-stage surge (667% and 2200%), while at pattern II, it triggered a stepwise deceleration (reductions of 79% and 75%). Furthermore, a mechanism of \"Interfacial Barrier\" was proposed, where gravitational force, viscous force (Fη), and Fh jointly contribute to energy storage and dissipation across the interface. Additionally, droplet impact experiments validated that the greater the interfacial wettability difference, the stronger the energy storage or dissipation effect. This study establishes the \"Smart\" valve as an efficient and precise fluid control solution that requires no external power, applicable in fields such as chemical engineering, biomedicine, and microfluidics.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144148730","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}

While previous reports that proved the wettability of materials play a crucial role in the fog collection process, the underlying mechanism remains unclear. Despite the focus on convex-backed beetles, hydrophobic smooth-backed beetles like Onymacris unguicularis also efficiently harvest fog. Through comprehensive investigation, the enhancement of fog collection efficiency on hydrophobic surfaces was attributed to the in situ 3D patterning process of microdroplets. Hydrophobic surfaces form dynamic liquid bumps that disturb airflow, improving the capture of tiny fog droplets. With a harp-like collector configuration, the superhydrophobic surface further enhances efficiency by 57% compared to superhydrophilic collectors. COMSOL Multiphysics simulations show that surfaces with stronger hydrophobicity and lower contact angle hysteresis intercept fog droplets more effectively.

These sensors offer flexibility, biocompatibility, and the ability to detect both static and dynamic forces, making them highly suitable for wearable electronics, robotic skins, and human-machine interfaces. However, conventional piezoionic sensors suffer from low output signals and slow response times due to inefficient ion transport and charge separation. To address these limitations, we propose a multilayered piezoionic sensor incorporating positively and negatively charged surface layers to create a controlled charge gradient. This design enhances ion mobility and reduces binding energy between ion pairs, and accelerates charge redistribution, leading to significantly improved sensing performance. The proposed sensor achieves an enhanced output current of 1.2 μA and a rapid response time of 19 ms, demonstrating superior sensing performances compared to single-layer designs. Additionally, the sensor effectively detects both static and dynamic forces, including vibration stimuli for surface texture detection, and enables air flow mapping by distinguishing both direction and intensity.
