The piezoelectric coefficient (d33) and mechanical quality factor (Qm) determine the quality of the radiation performance of the antenna device and, therefore, play a pivotal role in antenna preparation and selection. However, achieving high values for both d33 and Qm simultaneously proves challenging, as these properties often tend to compete with each other. Herein, we address this challenge by introducing MnCO3-modified lead magnesium niobate (PMN)-PZT piezoelectric ceramics, leveraging elements doping to achieve a well-balanced performance, where the d33 was optimized to 530 pC/N, while concurrently attaining a Qm of 624, being attributed to the synergistic contributions from the defect dipole and lead vacancies. Notably, the PMN-PZT-based antenna device exhibits a significantly enhanced converse ME coefficient αCME = 0.138 Oe·cm/V, which improves the antenna emission performance by about 25% compared to commercial PZT-4 samples. These findings offer a promising theoretical foundation and a feasible technical pathway for the development and design of ME antennas in the future.","PeriodicalId":200,"journal":{"name":"Journal of the American Ceramic Society","volume":"108 5","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143530604","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}

Atomistic simulations of Σ3 and Σ9 grain boundaries showed that trivalent ions of varying ionic radii [Sc3+ (74.5 pm), In3+ (80.0 pm), Y3+ (90.0 pm), and Nd3+ (98.3 pm)] have a tendency to segregate to both interfaces, with Y3+ presenting the highest segregation potentials. The connection between segregation and the reduction of interfacial energies was explored by measuring the grain boundary energy on nanoceramics fabricated via high-pressure spark plasma sintering (HP-SPS) using differential scanning calorimetry (DSC). The results revealed that Y3+ doping at 0.5 mol% reduces the grain boundary energy in zinc aluminate nanoceramics from 1.1–1.3 J/m2 to 0.6–0.8 J/m2; the range correlates with the observed size dependence of the excess energy, with higher values observed for the smaller grain sizes (∼17 nm). The noted decrease in interfacial energies for doped samples suggests it is indeed possible to alter the stability of zinc aluminate grain boundaries via dopant segregation.","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":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jace.20383","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143530735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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}

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%.

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.
