Here, we propose a simple strategy for the fabrication of multifunctional silk fabric-based ionogels (BSFIGs). The resulting fabric ionogels exhibits superior mechanical properties, with high tensile strength (11.3 ​MPa) and work of fracture (2.53 ​MJ/m³). And its work of fracture still has 1.42 ​MJ/m³ as the notch increased to 50 ​%, indicating its crack growth insensitivity. These ionogels can be used as sensors for strain, temperature, and tactile multi-mode sensing, demonstrating a gauge factor of 1.19 and a temperature coefficient of resistance of −3.17/°C^-1. Furthermore, these ionogels can be used for the detection of different roughness and as touch screens. The ionogels also exhibit exceptional optical transmittance and environmental stability even at −80 ​°C.

However, in recent years, the area of silicon photonics has experienced remarkable advancements and notable leaps in performance. The performance of silicon on insulator (SOI) based photonic devices, such as fast silicon optical modulators, photonic transceivers, optical filters, etc., have been discussed. This would be a step forward in creating standalone silicon photonic devices, strengthening the possibility of single on-chip nanophotonic integrated circuits. Suppose an integrated silicon photonic chip is designed and fabricated. In that case, it might drastically modify these combined photonic component costs, power consumption, and size, bringing substantial, perhaps revolutionary, changes to the next-generation communications sector. Yet, the monolithic integration of photonic and electrical circuitry is a significant technological difficulty. A complicated set of factors must be carefully considered to determine which application will have the best chance of success employing silicon-based integrated product solutions. The processing limitations connected to the current process flow, the process generation (sometimes referred to as lithography node generation), and packaging requirements are a few of these factors to consider. This review highlights recent developments in integrated silicon photonic devices and their proven applications, including but not limited to photonic waveguides, photonic amplifiers and filters, on-chip photonic transceivers, and the state-of-the-art of silicon photonic in multidimensional quantum systems.

Early evaluating coating microdefects and detecting corrosion sites are urgent yet remain challenge to achieve. Herein, we propose a robust, universal and efficient fluorescence-based strategy for hierarchical warning of coating damage and metal corrosion by introducing the concepts of damage-induced fluorescence enhancement effect (DIE) and ionic-recognition induced quenching effect (RIQ). The coatings with dual-responsiveness for coating defect and steel corrosion are constructed by incorporating synthesized nanoprobes composed of metal organic frameworks (Ni–Zn-MOFs) loaded with Rhodamine B (RhB@MOFs). The initial damage to the coating causes an immediate intensification of fluorescence, while the specific ionic-recognition characteristic of RhB with Fe³⁺ results in an evident fluorescence quenching, enabling the detection of coating damage and corrosion. Importantly, this nanoprobes are insensitive to the coating matrix and exhibit stable corrosion warning capability across various coating systems. Meanwhile, electrochemical investigations indicate that the impedance values of RM/EP maintain above 10⁸ ​Ω ​cm² even after 60 days of immersion. Therefore, the incorporation of fluorescent nanoprobes greatly inhibits the intrusion of electrolytes into polymer and improves the corrosion protection performance of the coating. This powerful strategy towards dual-level damage warning provides insights for the development of long-term smart protective materials.</div></div>","PeriodicalId":33573,"journal":{"name":"Nano Materials Science","volume":"7 3","pages":"Pages 326-339"},"PeriodicalIF":9.9,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140771024","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}

This reliance on lasers, however, also introduces a bottleneck for precision optical metrology, as it requires sophisticated photonic infrastructure for precise laser-wave control, leading to limited metrology performance and significant system complexity. Here, we take a key step toward overcoming this challenge by demonstrating a Pockels laser with multifunctional capabilities that elevate optical metrology to a new level. The chip-scale laser achieves a narrow intrinsic linewidth down to 167 Hz and a broad mode-hop-free tuning range up to 24 GHz. In particular, it delivers an unprecedented frequency chirping rate of up to 20 EHz/s and an exceptional modulation bandwidth exceeding 10 GHz, both of which are orders of magnitude greater than those of existing lasers. Leveraging this laser, we successfully achieve velocimetry at 40 m/s over a short distance of 0.4 m, and measurable velocities up to the first cosmic velocity at 1 m away—a feat unattainable with conventional ranging approaches. At the same time, we achieve distance metrology with a ranging resolution of &lt;2 cm. Furthermore, for the first time to our knowledge, we implement a dramatically simplified architecture for laser frequency stabilization by directly locking the laser to an external reference gas cell without requiring additional external light control. This approach enables long-term laser stability with a frequency fluctuation of only ±6.5 MHz over 60 min. The demonstrated Pockels laser combines elegantly high laser coherence with ultrafast frequency reconfigurability and superior multifunctional capability.

The strong optical anisotropies of these perovskite systems, driven by significant refractive index contrasts and robust excitonic resonances at room temperature, enable the emergence of synthetic magnetic fields that mediate photonic and polaritonic interactions.
