Compared with liquid electrolytes, solid-state electrolytes offer higher safety and energy density and are expected to further broaden the application fields of lithium-ion batteries. Conventional solid-state lithium-ion batteries (SSLIBs) employ lithium metal as their anode, which raises new concerns about their safety and waste management. Therefore, silicon, with high safety, high theoretical capacity, low electrochemical plateau, and low handle cost, has become the most promising new-generation anode material. However, due to the volume expansion of silicon and the low contact with solid-state electrolytes, resulting in poor conductivity, the SSLIBs' capacity has not reached the expected level and the cycle performance is also poor. Therefore, further modification of silicon anodes has become one of the key points in the development of SSLIBs. This paper comprehensively expounds on the application and optimization of silicon anodes in SSLIBs. It proposes further optimization strategies, which focus on preventing the destruction of silicon and extending its lifespan. The strategies include (1) silicon with different morphologies; (2) the formation of amorphous silicon; and (3) silicon composites.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143955875","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}

In general, it is believed that the electrostain originates from three main aspects: electric field-induced phase transitions with volume changes, non-180° domain switching, and lattice stretching without volume changes. However, the individual contribution remains to be quantitatively understood. In this work, in situ synchrotron X-ray diffraction in different integration directions is performed to quantify the contributions of electric field-induced phase transition and non-180° domain switching to electrostrain for NBT-based ergodic relaxor ferroelectrics under external electric field. The calculated total strain is 0.41%, in which 0.038% results from volume strain related to the electric field-induced phase transition, while 0.127% is due to induced ferroelastic domain structures. The rest 0.245% is attributed to lattice stretching. The volume change caused directly by phase transition has a very limited effect on electrostrain, while the indirect effect of phase transition on strain (the domain switching of the ferroelectric phase) has a relatively large effect on electrostrain. This innovative work offers theoretical insights for optimizing NBT-based relaxor ferroelectric materials for actuator applications, contributing to better control of electrostrain.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143955850","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}

Covalent organic frameworks (COFs) have emerged as a promising platform to address this challenge and enable more sustainable lithium extraction, owing to their unique advantages such as precisely tunable pore sizes, robust stability, and the ability to incorporate functional binding sites for selective ion transport. This review focuses on structural design and functionalization strategies in COFs to optimize lithium-ion separation, highlighting how pore confinement effects, tailored interlayer stacking arrangements, and strategic functional group modifications can dramatically enhance Li+ selectivity over competing ions present in brine solutions. A particular emphasis is placed on the fundamental energy barriers associated with lithium-ion transport. In particular, we discuss how appropriately designed pore environments and lithium-binding functional groups reduce the dehydration energy required for Li+ to enter and traverse COF nanochannels, thereby facilitating faster and more selective Li+ conduction. We also survey recent advancements in COF-based lithium separation technologies, such as high-performance COF membranes and sorbents for extracting lithium from brines and seawater, evaluating their potential, as well as remaining challenges, for sustainable industrial implementation. This review provides a comprehensive understanding of how advanced COF engineering can enable efficient and selective lithium-ion transport, offering valuable insights for the development of next-generation lithium extraction materials and technologies.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143951686","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}

Nonetheless, oral probiotics encounter challenges such as limited bioactivity, brief retention time, intricate pathological conditions, and singular efficacy. Here we designed plant-derived 18β-glycyrrhetinic acid (18β-GA) prodrug nanomicelles with ROS and inflammation-resolving capabilities, as well as anti-depressant effects, to protect probiotics and amplify their therapeutic effects in alleviating UC and UC-associated depression-like behaviors. Upon oral administration to UC lesion sites, prodrug nanomicelles can be dissociated by excessive ROS and release 18β-GA to attenuate colonic inflammatory responses and oxidative stress, which in turn provided a favorable microenvironment for LGG to repair intestinal barrier integrity and restore the gut microbiota. The synergistic therapeutic effects of STG nanomicelles and LGG alleviated UC-associated depression-like behavior by suppressing the activation of microglia and reducing neuroinflammation. This study introduces a promising strategy for oral nanomedicine with satisfactory therapeutic outcomes for the treatment of inflammatory diseases by integrating naturally derived small-molecule drugs with probiotics.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143953425","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, lattice metamaterials composed of soft materials have been far less explored due to challenges posed by material nonlinearity and large deformations. Here, hyperelastic lattice metamaterials with curved microstructures are fabricated by 3D printing elastomers and are developed to mimic bionic S-shaped stress-strain behaviors. We propose a design framework for 3D printed hyperelastic lattice metamaterials that integrates digital geometry generation, hierarchical mechanics modeling, and validation by finite element (FE) simulations and experiments. The microstructures are modeled through deriving a Timoshenko-type beam theory governed by hyperelastic strain energy potentials. The model is then combined with the deformation and equilibrium analysis considering non-rigid connections between microstructures to predict the mechanical responses of hyperelastic lattice metamaterials. Using the developed design framework, programmable S-shaped stress-strain behaviors and high fracture strains (over 800%) are achieved. We demonstrate S-shaped stress-strain curves that match skeletal and cardiac muscles and highly stretchable lattice sensors for remote controls.

Hydrogen peroxide (H2O2) is a green oxidant and clean energy widely used in sterilization, degradation of pollutants and as an energy carrier, which is one of the important strategies to solve these two major problems. In recent years, solar-driven photocatalytic production of H2O2 has gained significant attention and been extensively studied. Two dimensional (2D) material photocatalysts offer promising prospects and distinct advantages for H2O2 production. However, their performance is hindered by challenges such as rapid electron-hole recombination, wide bandgaps, and slow reaction kinetics. Additionally, the high solubility of H2O2 in water and its tendency to decompose easily make it difficult to recover from solutions containing sacrificial agents, thereby restricting its practical applications. To the best of our knowledge, there are few reviews focused on the photocatalytic production of H2O2 using 2D material composite catalysts and its in situ applications. This review provides a detailed discussion of various strategies, including introducing vacancy defects, elemental doping, heterojunction engineering, functionalization and multi-strategy coupling, to improve the photocatalytic performance of 2D material composite photocatalysts. Furthermore, this review highlights the in situ applications of H2O2 produced through photocatalysis in diverse fields, including water purification, sterilization, and pharmaceutical intermediate synthesis.

However, cathodic electrochromic electrodes suffer from ion trapping induced performance degradation upon long-term cycling. Here, we present guidelines for designing electrolytes and preventing ion trapping to achieve optimal durability. Specifically, by controlling the solvation energy of the salts in the electrolyte, anions can be prevented from penetrating the cation-solvent sheath, thereby inhibiting their involvement in the ion trapping process. Therefore, cycling stability is significantly extended, i.e., no observed degradation after 1000 cycles. Following this concept, we further reveal that for the degraded electrodes which cannot be restored in an electrolyte with relatively weak cation-solvent interaction, they can be successfully recovered by switching to an electrolyte with strong cation-solvent interaction. Our work not only provides strategies to suppress the ion trapping and prolong the cycling stability of electrochromic electrodes, but also evokes the importance of electrode-electrolyte interaction to the electrochromic community.","PeriodicalId":87,"journal":{"name":"Materials Horizons","volume":" ","pages":""},"PeriodicalIF":12.2,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143955936","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}
