However, the power consumption of most reported artificial synaptic devices remains substantially higher than that of their biological counterparts, which operate at the femtojoule (fJ) level per synaptic event. To this end, this research aims to develop ultralow-power silicon carbide (SiC) plasmonic nanowire network (NWN)-based artificial synaptic devices for using in musical classification neural network system. By leveraging the neural network-like physical architecture of the NWN and the alteration of conductance states at NW-NW junctions, the SiC/SiO₂@Ag NWN devices successfully emulate both ultraviolet (UV) visual and electrical synaptic functions under both externally biased electric field modulation mode and zero-bias photoexcitation mode conditions. Furthermore, due to the confinement effects of one-dimensional nanomaterials and the localized surface plasmon resonance (LSPR) induced by Ag nanoparticles, these devices exhibit substantial synaptic responses at ultra-low currents with minimal power consumption. With its low power consumption, the SiC/SiO₂@Ag NWN synapses exhibit superior performance in simulating music classification recognition, achieving an accuracy exceeding 95% within 20 epochs. Notably, the innovative SiC NWN structure ensures robust synaptic performance and high precision in neural network computations. This advancement has the potential to drive the development of novel computing architectures, such as spiking neural networks (SNNs), which more closely mimic the operational principles of biological neural networks, thereby facilitating enhanced music information processing.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":773,"journal":{"name":"Science China Materials","volume":"68 10","pages":"3703 - 3714"},"PeriodicalIF":7.4,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145248288","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 recent years, chiral metal nanoclusters (NCs) have emerged as a cutting-edge research frontier in asymmetric catalysis due to their precisely tunable structural attributes at the unprecedented atomic level, as well as their hierarchical structures reminiscent of natural proteins. It has become known that chirality can emerge at diverse structural hierarchies, including metal core, metal-ligand interface, ligand body, and assembly patterns of metal NCs, offering an ideal platform to not only boost the catalytic activity but also understand the catalytic mechanism in asymmetric reactions. This review systematically summarizes recent progress in the synthesis and asymmetric catalytic applications of chiral metal NCs, based on their core-shell structure scheme. The discussion starts with a brief elaboration on the structural origin of cluster chirality, followed by a concise account of the synthetic methodologies delivering enantiopure metal NCs. Before concluding this review with our perspectives on metal NCs-based asymmetric catalysis, the catalytic applications of chiral metal NCs are outlined.

Moreover, the zwitterionic hydration layer confers PCBUIA hydrogels with ultralow protein adsorption and markedly suppresses cell attachment; notably, it cannot provoke any foreign-body reaction or fibrotic capsule formation, demonstrating an outstanding biocompatibility.
