Summary: This paper aims to investigate the 3-D pore structure of cement paste at different scales using XCT and FIB/SEM. The results show that pore structures measured by FIB/SEM are more heterogeneous than those measured by XCT. Additionally, the pore connectivity decreases with decreasing water-cement ratio, increasing curing age, and the addition of fly ash/slag. The reduction in connectivity due to fly ash is more significant based on the observations by XCT compared to FIB/SEM. The transport-related tortuosity differs from geometric tortuosity, and the diffusional tortuosity exhibits a larger discrepancy from hydraulic tortuosity at lower porosity.

Summary: Nanoscale fabrication and characterization techniques are crucial for various fields, including nanoelectronics and nanobiotechnology. Focused ion beam (FIB) techniques are attractive due to their high spatial resolution and widespread use in processing nanostructured materials. In this study, we introduce FIB-induced fluorescence spectroscopy (FIB-FS) as a nanoscale technique for spectroscopic detection of ion-beam sputtered atoms. We demonstrate the nanoscale lateral and depth resolution using semiconductor heterostructures, and show that the resolution is limited by ion-induced intermixing of nanostructured materials. We also demonstrate the sensitivity of FIB-FS by depth profiling of quantum wells and detection of trace-level impurities. The utility of FIB-FS is demonstrated in the characterization of quantum wells and Li-ion batteries, combining the versatility of FIB nanofabrication techniques with the power of diffraction-unlimited fluorescence spectroscopy.

Summary: In this study, a physical model is presented to describe the effective electrical conductivity and percolation behavior in CB-based polymer nanocomposites. The presence of an interphase layer is shown to have a significant effect on the conductivity and percolation behavior. Experimental results validate the model's accuracy in predicting conductivity behavior in nanocomposites with different polymer matrices over a wide range of volume fractions, and it allows computation of percolation thresholds at very low volume fractions.

Summary: Composite modulation in the superparaelectric state of the BTBZ-CT system is proposed as an effective strategy to achieve both NTCC and excellent energy storage performance in dielectric ceramics. The addition of BZ and CT to BT ferroelectrics can move the SPE state to the normal use temperature zone, resulting in enhanced NTCC characteristics and energy storage performance. Furthermore, intentional precipitation of CT at grain boundaries can refine the grain size, increase the bandgap, and strengthen the local electric field distribution, thereby enhancing the breakdown electric field.

Summary: This study analyzes the influence of calcia refractory purity on the properties of calcia crucibles. Higher purity calcia results in well-developed grains and improved hydration resistance, leading to better high-temperature strength and thermal shock resistance. In contrast, lower purity calcia crucibles exhibit inferior properties. Therefore, high-purity calcia is considered a potential refractory for manufacturing oxide crucibles.

Summary: To raise the operating temperature of Si-based ceramic matrix composites (CMCs), researchers have applied thermal/environmental barrier coating (T/EBCs) materials, typically rare earth silicates. However, the high thermal conductivity and the mismatch of thermal expansion have been major challenges in developing new materials that can offer thermal insulation and environmental protection to CMCs. In this study, entropy engineering was used to create a multicomponent equi-atomic single-phase pyro silicate with extremely low thermal conductivity and enhanced water vapor corrosion resistance. The research findings show the potential of high entropy disilicates in achieving ultra-low thermal conductivity and low weight loss in corrosive environments.

Summary: This study provides an atomic-scale description of the high-velocity impact of alpha-Al2O3 particles onto an alpha-Al2O3 substrate during Aerosol Deposition (AD). The results suggest that the crystal orientation plays a crucial role in both plasticity and damage of the nanoparticles. Impact velocity has a direct correlation with plasticity and fragmentation, but adhesion efficiency has only a marginal increase. The crucial element lies in the substrate's surface alterations caused by the fragments left on the substrate after impact.

Summary: This study characterized the long-term and repeated ablation properties of modified Cf/HfC-SiC composites with YB4-Al2O3-Si3N4 under an air plasma torch. The structural stability and viscosity of the oxide layer were found to affect the ablation resistance of the composites. By forming nano c-HfO2 grains and high-viscosity Al-Si-Y-O glassy phase, the structural stability of the oxide layer was improved, resulting in enhanced ablation resistance. However, the oxidation of Si3N4 led to the formation of NO, NO2, and excessive SiO2 glassy phase, which resulted in a porous structure and reduced the viscosity of the oxide layer. Therefore, the addition of Si3N4 decreased the ablation resistance of the composites.

Summary: In this study, solid solutions of xBi(Ni1/2Hf1/2)O-3-(1 - x)PbTiO3 (xBNH-PT) were synthesized to investigate their phase boundary behaviors and physical properties. The presence of a tetragonal-pseudocubic phase boundary and a spontaneous ferroelectric-relaxor transition at specific compositions were confirmed. The introduction of a tetragonal-pseudocubic phase boundary improved the piezoelectric properties and suppressed the spontaneous ferroelectric-relaxor transition.
