Summary: This paper investigates the influence of thickness on the performance of ferroelectric thin films and reveals that thicker films enhance spontaneous polarization but decrease dielectric permittivity, coercivity field, residual polarization, efficiency, and energy density, and gradually transition the positive electrocaloric effect into a negative regime. These changes can be attributed to the variation of in-plane tensile stresses with thickness, resulting in an increase in the tetragonal phase and a decrease in the rhombohedral phase structure.

Summary: A stretch sensor made of a hydrothermally grown ferroelectric PZT film on titanium foil has been developed. The unique sensor structure converts the stretching motion of the PZT film to an out-of-plane deformation with linear strain variation, and converts the induced polarization into a voltage output. The measured data fits well with the derived equation, and the more accurate displacement obtained via the detected voltage will significantly benefit wearable stretch sensors.

Summary: A novel method for determining the optimal material coefficients of piezoelectric ceramics was presented, which minimizes the average relative error in values obtained from experimental measurements and modeling. This method considers elastic, piezoelectric, dielectric coefficients, and Poisson's ratio as complex numbers, and finds the global minimum of the average relative error by searching among local minima. The uncertainties in the optimal material coefficients were evaluated by calculating minimum average relative error with prescribed real or imaginary parts.

Summary: Hafnia doping improves the performance of environmental barrier coatings (EBCs) for SiC-based ceramic composites. The optimal doping ratio, HfO2 distribution, and oxidation mechanism of the bond layer are still under investigation. A prototype Si-HfO2 bond layer with a designed HfO2-rich area was used to study its oxidation behavior. Simulation results suggest that 20-30 vol% of HfO2 is the optimal doping ratio for well-dispersed HfO2 in Si. Oxidation experiments on Si-xHfO(2) tablets confirmed that the thinnest thermally grown oxide was achieved with 20 vol% HfO2-doped Si.

Summary: To lower the sintering shrinkage and avoid defects, slurries with high solid content and low viscosity are needed for ceramic components fabricated by vat photopolymerization technique. However, the viscosity of slurry increases dramatically with the increase of solid content, which affects the printing process and performance quality. A novel strategy of powder surface modification and dispersant selection was proposed to increase the solid load without significantly increasing viscosity.

Summary: A multilayer reconstruction strategy is employed to suppress the evolution of lattice oxygen and structure transformation in layered lithium-rich manganese-based oxide (LRMO) through facile pyrolysis. The multilayer interface is visually observed using advanced electron microscopy techniques. The suppressed evolution of lattice oxygen during initial charging eliminates the variation in unit cell parameters and prevents lattice distortion during long cycling, leading to improved Coulombic efficiency, rate capacity, and long-term stability of the modified LRMO. This study provides a surface reconstruction strategy to suppress anionic redox and offers insights for material design in high-performance lithium-ion batteries.

Summary: Bi2O3 is a promising sintering additive for YSZ that can decrease its sintering temperature and increase its ionic conductivity. However, the growth of Bi2O3 into large-sized rods and its addition inducing phase instability and precipitation of monoclinic ZrO2 are unfavorable for the electrical property. A microemulsion method was introduced to control the morphology and size of Bi2O3. Spherical Bi2O3 nanoparticles were obtained and nanosized Bi2O3-YSZ composite powders with good mixing uniformity dramatically decreased the sintering temperature and increased the conductivity of YSZ electrolytes.
