This review examines four primary mechanisms, namely, piezocatalysis, flexocatalysis, tribocatalysis, and sonocatalysis, each involving specific catalytic pathways for harnessing mechanical energy at the nanoscale. However, significant challenges arise in decoupling the effects related to each individual mechanism in order to better understand and manipulate their synergies. In this review, the fundamental principles underpinning MDC are systematically interpreted. Beyond mechanistic insights, recent advancements in performance enhancement strategies for these catalysts are highlighted. Potential applications using these mechanistic approaches in environmental remediation (pollutant and antibiotic degradation and microbial disinfection), renewable energy conversion (hydrogen production and greenhouse gas conversion), and biomedical treatments (particularly cancer therapy) are discussed. Finally, the mechanistic synergies and limiting factors are explored, addressing challenges related to the overlooked combined effects of ultrasound as the activation source, complexities in mechanical force interactions at the nanoscale, and the need for targeted application strategies. Additionally, the industrial potential of these catalytic processes with consideration to scalability and practical deployment is evaluated. While challenges remain, this review provides a roadmap for advancing mechanically driven catalyst design and implementation toward real-world applications, offering potential into its future trajectory and transformative impact across numerous fields.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"47 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143915771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The “freezing” silk fibroins not only bring the shape memory effect to elastic carbon nanotube sponges but also enable them to prop up heavy objects with loads exceeding 10,000 times their own weight. Also, the protein/CNTS hybrid achieves an ultrastiffness (over 10 MPa) and superelastic shape recovery (recovery strain >90%). Both experimental and numerical results indicate that the secondary conformational transition of silk fibroin plays a key role, where more α-helices/random coils transform into β-sheets under both confinement and low pressure.

EPs exist in diverse physical systems and give rise to many counterintuitive effects, offering rich opportunities to control the dynamics and alter the properties of optical, electronic, acoustic, and mechanical states. The last two decades have witnessed the flourishing of non-Hermitian physics and associated applications related to coalesced eigenstates at EPs in a plethora of classical systems. While stemming from the quantum mechanism, the implementation of EPs in real quantum systems still faces challenges of tuning and stabilizing the systems at EPs, as well as the additional noises that hinder the observation of relevant phenomena. This review mainly focuses on summarizing the current efforts and opportunities offered by quantum EPs that result from or produce observable quantum effects. We introduce the concepts of Hamiltonian and Liouvillian EPs in the quantum regime and focus on their different properties in connection with quantum jumps and decoherence. We then provide a comprehensive discussion covering the theoretical and experimental advances in accessing EPs in diverse quantum systems and platforms. Special attention is paid to EP-based quantum-optics applications with state-of-art technologies. Finally, we present a discussion on the existing challenges of constructing quantum EPs at the nanoscale and an outlook on the fundamental science and applied technologies of quantum EPs, aiming to provide valuable insights for future research and building quantum devices with high performance and advanced functionalities.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"3 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143910777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specifically, bioinspired chiral metasurfaces demonstrate strong chiroptical interactions with circularly polarized light, setting the stage for their role in next-generation optical technologies. In this study, a nature-inspired approach mimicking the structure of the Protaetia scarab beetle exoskeleton was applied to fabricate Bouligand meta-assemblies of magnetoplasmonic gold/iron oxide nanowires. By sputter coating a thin metallic platinum layer with controlled thickness, the fabricated structure exhibits amplified and tunable circular dichroism (CD) in transmission, diffuse reflectance circular dichroism (DRCD), and magnetic circular dichroism (MCD) modes within the ultraviolet and visible wavelength range. A strong enhancement of bisignate Cotton effects in the transmission CD spectrum was observed by adding a 30-nm-thick platinum layer, while a thinner metallic coating layer of 10 nm provided the strongest enhancement effect in DRCD mode. Additionally, the MCD study and computational optical simulations revealed the unique interplay of plasmonic coupling, enhanced absorption/reflection, and conformal inheritance of chirality as the origin of the enhancement effect of the metallic coating layer. The facile biomimetic fabrication technique provides multimodal control of the chiroptical Cotton effects, holding promises for applications in structural coloration, camouflage photonics, anti-counterfeiting, chiral sensing, and asymmetric catalysis.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"103 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143915768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, the metal–graphene (MG) interface has been considered straightforward, primarily affecting graphene’s work function through doping mechanisms. However, as device dimensions shrink to the sub-micrometer scale, subtle interfacial phenomena become increasingly significant. Here, we investigate transport phenomena occurring at high-quality, sub-micrometer metal contacts on graphene. Through transport measurements, electrostatic simulations, and first-principles calculations, we demonstrate that the metal contact induces a localized n-doped radial cavity, defined cooperatively by the metal-induced electrostatic potential and Klein tunneling. This mechanism leads to quantized energy states and secondary resistance peaks as a function of graphene doping that decrease with increasing contact size. In the presence of a perpendicular magnetic field, the cavity hosts a distinct set of Landau levels, resulting in the formation of a secondary bulk interacting with the intrinsic graphene bulk. This interplay enables the direct observation of topological edge states arising from bulk-boundary correspondence. Our results provide an improved understanding of metal–graphene interfaces, highlighting fundamental properties of graphene relevant for graphene-based nanoelectronic devices.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"62 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143915769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there exist two challenges of insufficient CO2 activation and fast charge carrier recombination, impeding this conversion. Herein, a hierarchical Co9S8@In2.77S4 (CoS@InS) heterojunction is developed by the in situ growth of the In2.77S4 nanosheets on the Co9S8 nanotubes for efficient photocatalytic reduction of CO2 to syngas in an aqueous reaction system with [Ru(bpy)3]Cl2 serving as a photosensitizer and triethanolamine as a sacrificial agent. In addition to the promoted charge separation and transfer, the strong interfacial electric field formed in this heterojunction tunes the p-band center of In active sites toward the Fermi level. Accordingly, the adsorption of the key intermediate *COOH is enhanced, and the energy barrier of *CO desorption is reduced. Besides, the hierarchical hollow structure enhances light utilization and mass transfer, increases the specific surface area, and provides abundant reaction sites. As a result, the hierarchical CoS@InS heterojunction exhibits superior activity. The optimized heterojunction yields CO and H2 production rates as high as 83,648 and 28,635 μmol g–1 h–1, respectively, with an apparent quantum yield of 5.60% at 450 nm.","PeriodicalId":21,"journal":{"name":"ACS Nano","volume":"25 1","pages":""},"PeriodicalIF":17.1,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143915934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The obtained d-RuO2 catalyst exhibits a low overpotential of 150 mV and long-term operational stability of 500 h at 10 mA cm–2, outperforming many Ru/Ir-based oxides ever reported. A PEMWE device using d-RuO2 sustains operation for 348 h at 200 mA cm–2. In-situ characterization reveals that the incorporation of lattice hydroxyl increases the Ru–Ru distance, which facilitates the turnover of the Ru oxidation state and promotes the formation of stable edge-sharing [RuO6] octahedra during the OER, thereby accelerating the formation of O–O bonds and suppressing the overoxidation of Ru sites. Additionally, the small particle size of the catalyst decreases the three-phase contact line and promotes bubble release.

This is particularly critical for polarized cells, such as neurons, where mRNA compartmentalization is essential for regulating gene expression, and defects in these localization mechanisms are linked to numerous neurological disorders. However, many subcellular analysis techniques require a compromise between subcellular precision, live-cell measurements, and nondestructive access to single cells in their native microenvironment. To overcome these challenges, we employ a single-cell technology that we have recently developed, the nanotweezer, which features a nanoscale footprint (∼100 nm), avoids cytoplasmic fluid aspiration, and enables rapid RNA isolation from living cells with minimal invasiveness. Using this tool, we investigate single-cell mRNA compartmentalization in the soma and dendrites of hippocampal neurons at different stages of neuronal development. By combining precise targeting with sequential sampling, we track changes in mRNA abundance at dendritic spine regions of the same neuron, both before and after stimulation. This minimally invasive approach enables time-resolved, subcellular gene expression profiling of the same single cell.
