Herein, ultrafine oxygen vacancy-rich Nb₂O₅ semiconductors are confined in carbon nanosheets (ov-Nb₂O₅/CNS) to boost dielectric polarization and achieve high attenuation. The polarization relaxation, electromagnetic response, and impedance matching of the ov-Nb₂O₅/CNS are significantly facilitated by the Nb₂O₅ semiconductors with rich oxygen vacancies, which consequently realizes an extremely high attenuation performance of − 80.8 dB (&gt; 99.999999% wave absorption) at 2.76 mm. As a dielectric polarization center, abundant Nb₂O₅–carbon heterointerfaces can intensify interfacial polarization loss to strengthen dielectric polarization, and the presence of oxygen vacancies endows Nb₂O₅ semiconductors with abundant charge separation sites to reinforce electric dipole polarization. Moreover, the three-dimensional reconstruction of the absorber using microcomputer tomography technology provides insight into the intensification of the unique lamellar morphology regarding multiple reflection and scattering dissipation characteristics. Additionally, ov-Nb₂O₅/CNS demonstrates excellent application potential by curing into a microwave-absorbing, machinable, and heat-dissipating plate. This work provides insight into the dielectric polarization loss mechanisms of nano-semiconductor/carbon composites and inspires the design of high-performance microwave absorption materials.</p><figure><div><div><div><picture><source><img></source></picture></div></div></div></figure></div>","PeriodicalId":48779,"journal":{"name":"Nano-Micro Letters","volume":null,"pages":null},"PeriodicalIF":26.6,"publicationDate":"2023-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-023-01151-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4577565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comparing to conventional lithography-based manufacturing methods which face significant challenges for 3D device architectures, additive manufacturing approaches such as direct ink writing offer convenient, on-demand manufacturing of 3D oxides with high resolutions down to sub-micrometer scales. However, the lack of a universal ink design strategy greatly limits the choices of printable oxides. Here, a universal, facile synthetic strategy is developed for direct ink writable polymer precursor inks based on metal-polymer coordination effect. Specifically, polyethyleneimine functionalized by ethylenediaminetetraacetic acid is employed as the polymer matrix for adsorbing targeted metal ions. Next, glucose is introduced as a crosslinker for endowing the polymer precursor inks with a thermosetting property required for 3D printing via the Maillard reaction. For demonstrations, binary (i.e., ZnO, CuO, In₂O₃, Ga₂O₃, TiO₂, and Y₂O₃) and ternary metal oxides (i.e., BaTiO₃ and SrTiO₃) are printed into 3D architectures with sub-micrometer resolution by extruding the inks through ultrafine nozzles. Upon thermal crosslinking and pyrolysis, the 3D microarchitectures with woodpile geometries exhibit strong light-matter coupling in the mid-infrared region. The design strategy for printable inks opens a new pathway toward 3D-printed optoelectronic devices based on functional oxides.\u0000</p><figure><div><div><div><picture><source><img></source></picture></div></div></div></figure></div>","PeriodicalId":48779,"journal":{"name":"Nano-Micro Letters","volume":null,"pages":null},"PeriodicalIF":26.6,"publicationDate":"2023-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-023-01147-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4543259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we address this issue by formulating a mechanistic understanding of bi-percolating ion channels formation and ion conduction across inorganic-polymer electrolyte interfaces in CSEs. A model CSE is composed of argyrodite-type Li₆PS₅Cl (LPSCl) and gel polymer electrolyte (GPE, including Li⁺-glyme complex as an ion-conducting medium). The percolation threshold of the LPSCl phase in the CSE strongly depends on the elasticity of the GPE phase. Additionally, manipulating the solvation/desolvation behavior of the Li⁺-glyme complex in the GPE facilitates ion conduction across the LPSCl-GPE interface. The resulting scalable CSE (area = 8 × 6 (cm × cm), thickness ~ 40 μm) can be assembled with a high-mass-loading LiNi_0.7Co_0.15Mn_0.15O₂ cathode (areal-mass-loading = 39 mg cm^–2) and a graphite anode (negative (N)/positive (P) capacity ratio = 1.1) in order to fabricate an SSB full cell with bi-cell configuration. Under this constrained cell condition, the SSB full cell exhibits high volumetric energy density (480 Wh L_cell⁻¹) and stable cyclability at 25 °C, far exceeding the values reported by previous CSE-based SSBs.</p><figure><div><div><div><picture><source><img></source></picture></div></div></div></figure></div>","PeriodicalId":48779,"journal":{"name":"Nano-Micro Letters","volume":null,"pages":null},"PeriodicalIF":26.6,"publicationDate":"2023-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-023-01139-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4542859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The multicarbon (C₂₊) products, especially ethylene, are of great interest due to their versatile industrial applications. However, selectively reducing CO₂ to ethylene is still challenging as the additional energy required for the C–C coupling step results in large overpotential and many competing products. Nonetheless, mechanistic understanding of the key steps and preferred reaction pathways/conditions, as well as rational design of novel catalysts for ethylene production have been regarded as promising approaches to achieving the highly efficient and selective CO₂RR. In this review, we first illustrate the key steps for CO₂RR to ethylene (<i>e.g.</i>, CO₂ adsorption/activation, formation of *CO intermediate, C–C coupling step), offering mechanistic understanding of CO₂RR conversion to ethylene. Then the alternative reaction pathways and conditions for the formation of ethylene and competitive products (C₁ and other C₂₊ products) are investigated, guiding the further design and development of preferred conditions for ethylene generation. Engineering strategies of Cu-based catalysts for CO₂RR-ethylene are further summarized, and the correlations of reaction mechanism/pathways, engineering strategies and selectivity are elaborated. Finally, major challenges and perspectives in the research area of CO₂RR are proposed for future development and practical applications.</p>\u0000 <figure><div><div><div><picture><source><img></source></picture></div></div></div></figure>\u0000 </div>","PeriodicalId":48779,"journal":{"name":"Nano-Micro Letters","volume":null,"pages":null},"PeriodicalIF":26.6,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-023-01146-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4459611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
