SEs are categorized into organic (polymer) and inorganic (ceramic) electrolytes, with this review focusing on inorganic solid electrolytes (ISEs). The main obstacles to high-performing ISEs are poor ionic conductivity at room temperature and high impedance at the electrode-electrolyte interface. Many strategies to improve the conductivity and interface have been attempted and are highlighted in detail in this review. This review commences by detailing the ion conduction mechanisms in ISEs, including halides, phosphates (NASICON), oxides (perovskite, antiperovskite, and garnet), and sulfides (argyrodite-type, LGPS-type, and LISICON). The review further explores the influence of defect chemistry, elemental substitution, ion migration pathways, ion doping, and phase stability on ionic mobility and interface in ISEs. Theoretical calculation and experimental characterization are discussed in parallel to give a comprehensive and deep grasp of ion movement and interfaces. Additionally, various nuclear magnetic resonance (NMR) techniques have been explored, such as NMR relaxometry to examine both slow and rapid bulk ion transport in ISEs, PFG-NMR to investigate ion self-diffusivity, and 2D NMR exchange spectroscopy (2D EXSY) to study ion exchange mechanisms. The review concludes by discussing dynamic nuclear polarization (DNP) as a hyperpolarization technique to enhance NMR sensitivity for electrode-electrolyte interfacial studies, and by proposing future research directions for ISEs.</div></div>","PeriodicalId":100958,"journal":{"name":"Next Materials","volume":"8 ","pages":"Article 100657"},"PeriodicalIF":0.0,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143844546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our results indicate that accurate characterization requires careful selection of ultrasonic propagation paths, which must consider the direction of additive layering, variations in processing parameters, and the component's geometry. We employed two distinct methods to estimate material properties from ultrasonic data: One assumes isotropy, while the other accounts for anisotropic interactions during the propagation of elastic waves. When applied to samples fabricated with laser energy densities ranging from 24 to 42 J/mm³ , these methods revealed transverse isotropy and weak anisotropy (quantified by small Thomsen parameters, <span><math><mrow><mi>ε</mi><mo>=</mo><mspace></mspace></mrow></math></span>0.0651 and <span><math><mrow><mi>γ</mi><mo>=</mo><mspace></mspace></mrow></math></span>0.0092) and less than a ∼6 % change in acoustic impedance. The assumption of isotropy, in this case, leads to small errors (less than 4 % or 1 % for Young's modulus in the build or transverse directions) when estimating orthotropic material properties using ultrasonic data measured along just two orthogonal directions, one of which must align with the build direction. By comparing ultrasonic measurements — which aggregate the spatial variability in material properties along the length of elastic wave propagation into a single value — with localized measurements obtained from surface nanoindentation, we uncovered and spatially profiled significant differences between the surface and interior properties. Specifically, the surface Young's modulus decreased from approximately 210 GPa to 180 GPa within a depth of about 3 mm. We attribute this surface-localized heterogeneity in PBF-fabricated components to distinct thermal histories experienced by the surface and interior regions. Collectively, the results of this study establish a framework for the ultrasonic characterization of material heterogeneity and anisotropy in material properties and demonstrate its application in additively manufactured metal components.</div></div>","PeriodicalId":100958,"journal":{"name":"Next Materials","volume":"8 ","pages":"Article 100614"},"PeriodicalIF":0.0,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143776603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
