Traditional electromagnetic materials with fixed responses and performance after manufacturing, fail to meet the requirements for reconfigurable and multi-frequency protection. Inspired by the moth surface cilia to bend and evade bat sonar detection, our work introduces a metamaterial featuring broadband and tunable microwave absorption (MA) characteristics. In material systems, polyurethane (TPU) elastomers are used to reinforce CPLA matrices, balancing the mechanical properties and shape memory properties of 4D-printed composite materials for shape reconfigurable requirements under multi-physical fields. In structural design, we implement multi-unit encoding strategies to enlarge the dimensions of absorption regulation. In the optimization method, we provide a Deep Q-Network high-dimensional morphological intelligent optimization design method. The final 5 × 5 array achieves broadband, tunable MA effects in the 5.6–18 GHz range.

In this work, the concentration of oxygen vacancies (<i>V</i><sub>O</sub>) and the degree of lattice distortion in spinel oxides were successfully regulated by implementing a heteroatom doping strategy, which enhanced the structural stability as well as the optimization of the permittivity. However, the description of the polarization mechanisms in spinel structures is currently unclear. Therefore, carbon cloth (CC) surface was constructed with modified spinel structure to form nanosheet arrays (C@NMC). Localized electronic reconfiguration and altered spinel configurations were achieved by modulating manganese (Mn) substitution at specific metal sites. The lattice distortion activated dipole polarization, which increased the permittivity of the CC material to twice its original value. As a result, Mn–doped C@NMC samples (C@NMC–0.2) demonstrate a reflection loss (RL) of −63.40 dB (2.06 mm) and an effective absorption bandwidth (EAB) of 4.80 GHz. This work achieves precise regulation of dielectric properties through atomic–level defect engineering, while establishing a synergistic model between structural stability and polarization paths at the experimental level.

However, Ca plating/stripping at room temperature (r.t.) is severely impeded by the formation of ion-insulating passivation layers. Constructing artificial protective layers that can effectively transport Ca<sup>2+</sup> on Ca metal is crucial for realizing practical CMBs. Nonetheless, identifying a suitable candidate that is both highly ionic conductive (&gt;10<sup>−4</sup> S cm<sup>−1</sup> at r.t.) and electrically insulating remains a formidable challenge. Ionic covalent organic frameworks (iCOFs) represent a distinctive class of porous, crystalline polymers containing ionic moieties to facilitate ion conduction in batteries. In this study, we introduce, for the first time, single-ion conductive sulfonate iCOFs with a Ca<sup>2+</sup> transference number of 0.95 and ionic conductivity of 2.23 × 10<sup>−4</sup> S cm<sup>−1</sup> at r.t. as artificial protective layers for the Ca metal anode. This iCOF protective layer promotes uniform Ca deposition and effective anticorrosion of modified anodes.

Here, we design a miniaturized, modular, and skin-interfaced sweat sensing patch for rapid and efficient large-scale health monitoring and diagnosis through multimodal laser sensing. The patch's workflow involves sweat collection via a microfluidics-based collection module, followed by sweat sensing and artificial intelligence (AI)-assisted diagnosis. The sweat sensing module, prepared by coating silver nanowires on filter paper, enables rapid detection of multi-analytes (e.g., glucose, lactate, urea, sodium, potassium, and lead) using multimodal laser sensing techniques (that combine surface-enhanced Raman spectroscopy with nano-enhanced laser-induced breakdown spectroscopy). Furthermore, the multispectral data, analyzed with AI assistance, can rapidly and efficiently detect abnormalities in sweat components for quick diagnosis.

We investigated the effects of doping, bias voltage, gate voltage, and interface configurations on the device performance. We considered two types of lateral graphene/MoS<sub>2</sub> heterostructures, with graphene connected to either the S edge (C-S) or Mo edge (C-Mo) of the MoS<sub>2</sub>. Our calculations show magnetic coupling at the graphene/MoS<sub>2</sub> interfaces even though they are composed of non-magnetic materials, which is consistent with previous theoretical studies. The spin polarization effects degraded the rectification ratios of the graphene/MoS<sub>2</sub> rectifiers. However, n-type doping of MoS<sub>2</sub> could significantly enhance the rectification ratio of the C-S device to 10<sup>5</sup> and increase the current by an order of magnitude. The C-Mo device was shown to be highly suitable for spin filter applications, with a spin current polarization ratio of almost 100% under bias and gate voltage modulation. For optoelectronic applications, both types of lateral graphene/MoS<sub>2</sub> heterostructures exhibited high photocurrent peaks across the infrared, visible, and/or ultraviolet light regions, with a maximum photocurrent of 13 μA/mm<sup>2</sup> and suitable bias and gate voltages. Our study reveals the magnetic multifunctional nature of lateral graphene/MoS<sub>2</sub> heterostructure devices, and can serve as a theoretical guide for the design and modulation of high-performance multifunctional devices based on two-dimensional lateral heterostructures.</p><p>\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":48538,"journal":{"name":"Infomat","volume":"8 3","pages":""},"PeriodicalIF":22.3,"publicationDate":"2026-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inf2.70111","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147563289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
