We found that the surface cleaved in ambient air is completely oxidized, forming Co oxides and Sn oxides/hydroxides. This surface exhibits an overpotential of 503 mV to achieve a current density of 10 mA cm⁻² for OER. However, the UHV-cleaved surface maintains Co₃Sn₂S₂ pristine features, showing remarkably slow kinetics compared to the air-cleaved sample. Systematically tracking the oxidation process under various exposure conditions reveals that a small amount of Sn oxides forms upon exposures to O₂ and H₂O under UHV, while a strong interaction between Sn and liquid water occurs at atmosphere conditions. In contrast, higher exposed pressure promotes Co oxidation, resulting in the formation of Co oxides in atmospheric air, which correlates with enhanced catalytic activity. Despite unfavorable evidence regarding the surface robustness, this work provides crucial insights into Co₃Sn₂S₂ surface reactivity.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"10 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816016","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 study proposes a new strategy to prepare natural N/O co-doped bamboo-derived porous carbon using shrimp shells as multifunctional bio-templates. Shrimp shells exhibit multiple roles: proteins and chitin as a heteroatom source and CaCO₃ as a sacrificial hard template. The results show that the best carbon material (BC-SP-1) simultaneously displays a gravimetric capacitance of 311.45F/g and a volumetric capacitance of 283.98F/cm³. The aqueous symmetric supercapacitor (SS-BC-SP-1) and the Zn-ion hybrid supercapacitor (ZHSC-BC-SP-1) exhibit excellent cycling stability. In addition, ZHSC-BC-SP-1 displays a high energy density of 97.44 Wh/kg. The density functional theory (DFT) calculations indicate that the existence of N/O functional groups significantly enhances the adsorption of Zn-ion on carbon materials, especially pyrrolic N, quinone, and ether groups. In this study, the effects of heteroatom functional groups on the electrochemical properties of carbon materials are analyzed from multiple perspectives using experiments and simulations. This work utilizes shrimp shells as green bio-templates to optimize carbon material structure and enrich heteroatom, laying the foundation for the green synthesis of high-performance biomass-derived carbon electrode materials.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"15 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142816020","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}

By varying the TDC amount, the solid-state emissive color of CNS samples can be manipulated from blue to orange-red.

These properties make CNS highly suitable for multi-color light-emitting diodes (LED) applications, particularly in WLEDs with chromaticity coordinates (0.341, 0.359).

However, the role of phase interfaces in the dynamic deformation of these nano lamellar systems remains poorly elucidated, primarily because of the challenges pertinent to real-time characterization at nanoscopic resolutions. Here, the intricate interplay between shock waves and phase interfaces in face/body-centered cubic (FCC/BCC) FeCoNiCu_xAl_1-x HEA nanolaminates was examined, through performing large-scale molecular dynamics (MD) simulations. As a consequence of stress concentration at interfaces, shock waves with intensities beneath the Hugoniot elastic limit (HEL) were confirmed to trigger dislocation at these interface sites. These dislocations slipped in directions counter to that of deformation-induced ones, making them susceptible to collisions and subsequent dislocation reactions, which effectively fostered the emergence of immobile Hirth dislocations and thus an additional strain-hardening effect. Meanwhile, the BCC phase was demonstrated to undergo deformation through a transformation into a hexagonal close-packed (HCP) structure upon exposure to shock waves, accompanied by twinning within emergent HCP lamellae. This would contribute to dissipating energy from the propagating shock waves. More interestingly, the magnitude of both phase transition and twinning can be dynamically manipulated through the strategic manipulation of Cu/Al compositional ratios in the BCC phase. In addition, the layer-thickness difference was corroborated to dramatically affect the dynamic deformation behavior of DP-HEA systems. A decrease in layer thickness allowed a more frequent interaction between shock waves and phase interfaces, alleviating stress concentration and encouraging greater plastic deformation. Our current study illuminates the dynamic deformation characteristics of DP-HEAs, offering pivotal insights that can design and develop HEAs with optimized properties for future applications.","PeriodicalId":247,"journal":{"name":"Applied Surface Science","volume":"10 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820690","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}

To overcome these drawbacks, magnetic Co@CNT is decorated on the short carbon fiber (SCF) surface by In-situ growth method to enhance the interfacial characterizations of SCFRCs. The results demonstrate that the application of Co@CNT results in a dramatic increase of tensile strength, flexural strength and modulus by 250 %, 160 % and 190 %, respectively, compared to the pure SCF-epoxy (EP) composite. The primary reason can be attributed to the formation of a Co@CNT interfacial region between the short-cut carbon fiber (SCF) filler and the epoxy (EP) matrix in the composites. This interfacial region facilitates efficient stress transfer from the matrix to the surface-modified SCF filler, leading to enhanced mechanical properties of the SCF-EP composites. In addition, Co@CNT-modified SCFRCs obtained EMI shielding effectiveness as high as 59 dB in X-band, which is about 2.3 times that of pristine SCF-EP composite. The excellent EMI shielding effectiveness is ascribed to enhanced dielectric loss and magnetic loss caused by magnetic Co@CNT. Thus, the synergistic effect of magnetic Co and highly conductive CNT resulted in the improvement of mechanical properties and electromagnetic shielding properties.
