Supercapacitors are increasingly favored for the storage of energy owing to their large specific power, rapid charge/discharge times, and long-term durability. The potential electrochemical energy storage using metal oxides motivated our research team to create DyMnO3 and their hybrid with reduced graphene oxide (rGO), via hydrothermal process in rGO/DyMnO3, as an electrocatalyst with comparatively high electrical conductivity and appropriate electrochemical active surface. This research was conducted utilizing a 2 M KOH as electrolyte within a possible window between −0.1 and 0.6 V. Impressively, our synthesized sample exhibited the remarkable specific capacitance of 1536.78 F g−1 on current density of 1 A g−1, attributed to quick charge storage and delayed discharging mechanism. The addition of rGO to porous spherical DyMnO3 enhances electrochemical performance, providing a specific surface area of 250 m2 g−1 and an electroactive surface area of 2675 cm−2. The created device displayed electrochemical activity with a high energy density of 149.40 Wh kg−1 at a power density of 719.86 W kg−1, respectively. Oxygen vacancy enhances results, indicating the rGO/DyMnO3 nanocomposite's potential for SCs and other electrochemical applications.","PeriodicalId":200,"journal":{"name":"Journal of the American Ceramic Society","volume":"108 5","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143530733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As expected, the doped Cu2+ ions could effectively reduce the sintering temperature and increase the density of the ferrites. With increasing doping amount of Cu2+, the coercivity, saturation magnetization, and Curie temperature of the resultant ferrites decreased. With x = 0.15, the sample presented the maximum initial magnetic permeability and highest Q-factor. On the basis of the measured magnetic parameters, the ferrites were examined as magnetic sheet in wireless charging system by digital simulation, while the structural parameters of the system were considered and the coefficients of hysteresis loss, eddy current loss, and excess loss were quantitatively separated under sinusoidal excitation. Specifically, because of its lower core loss, the optimal ferrite (x = 0.15) would perform better with much improved transmission efficiency than that without the doping of Cu2+, especially when the transmitting and receiving coils were settled more apart, which might be a good candidate for wireless charging system, and the proposed simple wireless charging system can be used as a general strategy for the evaluation of magnetic sheets.","PeriodicalId":200,"journal":{"name":"Journal of the American Ceramic Society","volume":"108 5","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143530632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, TBCs finite element model and TBCs thermal fatigue life prediction model based on particle swarm optimization are conducted. Finally, the effect of ARI on the interface stress state and thermal fatigue life of the TBCs is discussed. The results show that the maximum error in the fatigue life prediction model of TBCs is only 45.3%, and the fatigue life prediction error for TBCs under similar operating conditions is only 30.8%. When the axial interface wavelength is 0.060 mm and the circumferential wavelength interface is 0.057 mm, the maximum equivalent stress at the interface is the smallest, with a value of 241.4 MPa. The thermal fatigue life is maximum when the axial wavelength interface is 0.060 mm and the circumferential wavelength interface is 0.049 mm, with the value of 639 cycles, which is the 47.6% increase in fatigue life compared with the initial roughness TBCs model (The interface wavelengths are all 0.040 mm).

The interaction between a crack and dislocations was analyzed to discuss the effect of crack-tip plasticity on fracture toughness. The present paper first demonstrates a dislocation configuration around a crack-tip in a MgO thin crystal, where the plastic zone called 45°-shear type is dominant under the plane stress condition. Then, the slip systems necessary for brittle-to-ductile transition in ionic crystals with the rock-salt structure are discussed based on the temperature dependence of stress-strain relationships and the aspect of crack front observed in NaCl crystals. Second, crack-tip dislocations near the surface of bulk Si crystals are exhibited based on the 3D analyses using HVEM tomography. We focus on a newfound plastic zone being perpendicular to the crack plane, which is different from either 45°-shear type or the hinge type generally well-known. The dislocation loops observed in this plastic zone fundamentally have a crack-tip shielding effect to increase fracture toughness. Still, in addition, they contribute to activating crack-tip dislocations by their localized antishielding field. These analyses reveal a fundamental toughening mechanism for crystalline materials.","PeriodicalId":200,"journal":{"name":"Journal of the American Ceramic Society","volume":"108 6","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tellurite glasses are particularly suitable as a gain medium due to their lower phonon energy and better rare-earth solubility compared to silica glass. Various strategies, such as reducing the OH content and co-doping with silver nanoparticles (Ag NPs), are attempted to improve the spectroscopic properties. However, maintaining the glass drawability into fibers when developing glasses with improved spectroscopic properties remains a significant challenge. Indeed, it is confirmed that NH4HF2 can be added into the tellurite glass batch prior to the melting to reduce OH− content. However, the presence of remaining F in the glass is demonstrated to have a detrimental impact on the glass thermal properties preventing the drawing of this glass into fiber. The successful drawing of a single-index optical fiber from a tellurite glass preform heavily doped with Er3+ ions is reported for the first time. The Ag NPs are grown in the fiber using a thermal treatment at the glass transition temperature. The presence of the NPs is confirmed using a TEM and from the spectroscopic properties. The interaction between Er3+ ions and the Ag species offers potential for modifying the luminescence properties of the fiber.","PeriodicalId":200,"journal":{"name":"Journal of the American Ceramic Society","volume":"108 5","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143530623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed Na3-2xCaxSbS4 glass–ceramic electrolytes were subsequently manufactured using ball milling and heat treatment. The results acquired the maximum ionic conductivity of 1.59 mS cm−1 at room temperature, which reached the commercial use level when compared with the current popular lithium-ion battery. Moreover, calcium ions partially replaced sodium sites while creating massive Na vacancies to maintain charge neutrality, resulting in fast ion transport. Furthermore, a more stable ionic bond Ca–S was formed at the interface, which inhibited additional reactions at the electrolyte–metal interface and demonstrated exceptional cyclic stability, making it a viable electrolyte for solid-state sodium-ion batteries.","PeriodicalId":200,"journal":{"name":"Journal of the American Ceramic Society","volume":"108 5","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143530657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of sputtering power on the structure, electrical properties, and electrical stability of films was investigated. The results showed that the increase of ion energy during sputtering promotes grain growth resulting in the decrease of resistivity. The selective oxidation and kinetically controlled oxidation during oxidation process caused the gradient distribution of Cr3+, which affected the sluggish diffusion effect and further lead to the better electrical stability of the films. Notably, the fastest Cr3+ diffusion rate had the highest disorder of the Cr3+ distribution in the 30 W films, whose resistivity drift rate under accelerated aging at 125°C for 400 h is reduced from 9.67% to 1.05%.

In the evaluation, systematic energetic trends of RE2O3 depending on ionic radius of RE and the extrapolated data from RE2O3 containing binary systems were taken into account to obtain more accurate thermodynamic property data and phase transition data. Based on the newly established Gibbs energies of unary RE2O3 phases, the CALPHAD-type thermodynamic modeling was carried out for inter RE2O3 binary systems to obtain the thermodynamic models with optimized model parameters of all solid and liquid solutions, which can successfully reproduce all available and reliable experimental phase diagram data of the binary RE2O3–RE′2O3 systems. Using thermodynamic models with established model parameters, a complete phase diagram set of all 136 binary RE2O3–RE′2O3 systems were predicted for the first time.
