Structural analysis of the samples by X‐ray diffraction, transmission electron microscopy, differential scanning calorimetry, Fourier transform infrared spectra, and optical absorption techniques indicated that the glasses are embedded with Ag3PO4, Ag2SeO3, and Zn3(PO4)2 anisotropic crystal phases along with Ag+ ions and Ag0 particles. Dielectric properties, ac conductivity (σac), and dielectric breakdown strength (DBS) are investigated as functions of Ag2O concentration. The results show the maximal concentration of Ag+ ions and Ag0 metallic particles in the sample containing 0.6 mol% of Ag2O. Dielectric parameters and (σac) increase with increasing Ag2O up to 0.6 mol%, while the DBS and electrical impedance decrease. The observed dipolar effects are quantitatively analyzed and possible dipoles are identified. Ionic contribution is predominant up to 0.6 mol% of Ag2O, beyond which the polaronic tunneling phenomenon prevails. These findings indicate that 0.6 mol% of Ag2O is the optimal concentration for using these glass ceramics as solid electrolytes in ionic batteries. Moreover, glass ceramics containing Ag2O beyond 0.6 mol% have exhibited larger polaronic conductivity, hence such glasses can be considered suitable candidates for electrodes in ionic batteries.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87052458","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}

In case of a large value of residual thermal stress, a weak interface forms between the second phase and the matrix material, reducing the strength of the material. Herein, a new type of core–shell structure silicon carbide SiC–glass phase is produced inside the material by adding a presintering process into the traditional SiC–Si3N4 sintering process. The radial and tangential thermal stresses around the core–shell structural SiC–glass phase and SiC particle are compared by using the finite element method. The results indicate that the core–shell structural SiC–glass phase inhibits the interfacial debonding. Compared with the introduction of SiC particle alone, the core–shell structural SiC–glass phase optimizes the mechanical properties of SiC/Si3N4 composite ceramic, with the fracture toughness reduced by 9.6%, the bending strength increased by 12.3%, and the friction coefficient reduced by 8.5% for the SiC/Si3N4 ceramics with SiC content of 5%.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73086368","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}

The Rietveld refinement of X‐ray diffraction patterns confirms the formation of the inverse spinel nickel ferrite phase with an additional orthorhombic phase PrFeO3. The crystallinity of those samples is better with a lesser weight percentage of the secondary phase for higher sintered samples. Structural parameters like crystallite size, lattice parameter, microstrain, and bond lengths depend strongly on sintering temperature with an increasing trend. Scanning electron micrographs clearly show the grain growth of the samples with sintering temperature with the formation of a secondary phase at the grain boundaries. The photoluminescence study points to the photocatalytic nature of the compositions. The bandgaps of the samples are calculated using a UV–vis study, which shows an initial decrease in values with increasing sintering temperature. The electrical study confirms the grain and grain boundary contribution to the total conductivity. With higher sintering temperatures, activation energies decrease, but the dielectric loss and saturation dielectric constant tend to increase. The scaling of conductivity and dielectric loss spectra confirm the time–temperature superposition principle.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"105 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80861200","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}

The antiopaline TiO2 photonic crystal (PC) structure is further prepared via immersed carbon nanospheres in TiO2 precursor solution, and the antiopal PC is used as the scattering layer of the photoanode of dye‐sensitized solar cell (DSSCs). As a comparison, the antiopal PC reflective layer is also prepared on the photoanode of DSSCs using polystyrene nanospheres as the template material. The photoanodes with those PC scattering layers prepared with different template materials are fabricated into complete DSSCs. The final photoelectric conversion efficiency of the DSSCs prepared with carbon nanospheres as the template material reaches 7.02%, which is comparable to the cells prepared with polystyrene nanospheres as the template material.
