Herein, we report the hopper-like NaCl and KCl crystals formed on the iron surface under rapid vacuum evaporation aided by organic molecules. Theoretical and experimental results indicate that it is attributed to the organic molecules alternating adsorption between {100} and {110} surfaces instead of adsorbing a single surface, as well as the fast crystal growth rate. Following this law, we found hopper-like crystals formed under natural evaporation conditions in salt lake crystals as well as synthesized kilogram-class hopper-like crystals. Interestingly, the hopper-like crystals can act as microcatalytic reactors to efficiently facilitate micro/nanoplastic degradation with ∼91.72% styrene yield, highly decreasing the degradation temperature from ∼400 to ∼275 °C. These findings provide an understanding of the growth mechanism of various crystals and a friendly environmental, low-carbon, and economical microcatalytic reactor for efficient micro/nanoplastic degradation.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"13 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143055444","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}

A novel approach is introduced, using a valence gradient in iron nanoparticles (Fe0, Fe2+, Fe3+) to stabilize the anodes. An Fe0 component, with fast Li diffusion, ensures a steady supply of Li to Fe2+ and Fe3+ components, which have slower Li diffusion. This coordinated interplay between fast and slow diffusion uniformizes Li deposition near the substrate, effectively reducing the rate of dendrite growth. The as-prepared framework demonstrates uniform Li plating with a minimal hysteresis voltage after extensive cycling for 1200 h in symmetric cells. Integrated into a full cell with LiFePO4, it demonstrates outstanding cycling stability for almost 950 cycles with a capacity of 92.2 mA h g–1 at 1C with an ultralow N/P ratio of 1.19. This valence gradient design strategy broadens the design potential for transition-metal compounds in regulating Li deposition by mitigating interfacial Li+ behavior.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"25 5","pages":"1783–1791 1783–1791"},"PeriodicalIF":9.6,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143127723","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}

Herein, a highly efficient photovoltaic–electrocatalytic system enabling high-rate solar-driven NH3 synthesis was developed. A high-performance Ru-doped Co nanotube catalyst was used to selectively promote the nitrite reduction reaction (NO2RR), exhibiting a faradaic efficiency of 99.6% and half-cell energy efficiency of 52.3% at 0.15 V vs the reversible hydrogen electrode, delivering a high NO2RR selectivity even in electrolytes with high NO3– and low NO2– concentrations.

An anionic poly(p-phenyleneethynylene) (PPE) polyelectrolyte wrapped single-walled carbon nanotube (SWNT) shows up to 200% turn-on and 85% turn-off responses to Fe(II) and Fe(III), respectively, allowing spatial and temporal analysis of iron uptake in both foliar and root-to-shoot pathways.

When aiming at dynamic applications such as AR/VR and LiDAR, high-quality factor (high-Q) phase gradient metasurfaces have emerged as a way to boost weak light–material interactions in flat-optical components. However, resonant features are naturally tied to polarization, limiting devices to operating on a single polarization state, which reduces the efficiency and adaptability of wave-shaping. Here, we propose polarization-independent high-Q phase gradient metasurfaces, where two cross-polarized dipolar guided mode resonances (DGMRs) with similar Q around 300 are spectrally aligned while being spatially tuned. Our simulations demonstrate that, by adding less than 5% geometric perturbation, the metasurface can steer arbitrarily polarized beams to 31° with diffraction efficiency >70%. These devices show potential for advancing programmable polarization-independent wavefront shaping and unlocking ways to efficiently sculpt nonlinear frequency generation and mixing processes.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"25 5","pages":"1862–1869 1862–1869"},"PeriodicalIF":9.6,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143127658","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}
