Summary: This study quantitatively analyzed the microstructural evolution and porous network development of Room Temperature Vulcanized (RTV) silicone pyrolysis at high temperatures using in situ high-temperature X-ray computed micro-tomography. The results showed that the microstructure evolution and porous network development were dependent on the heating rate, and the bulk sample volume change, porosity, pore network size, and densification were evaluated using X-ray attenuation. The findings of this study are important for the development of multi-physics models for thermal response.

Summary: The evolution of the condensed phase in solid propellants during combustion is crucial for understanding their behavior and achieving desired characteristics. However, due to phase opacity and deformation, in-situ characterization of the microstructure and gaseous products is lacking. This study uses in-situ synchrotron X-ray radiography and FT-IR spectroscopy to characterize the subsurface condensed-phase evolution. The obtained images reveal the microstructural changes and the FT-IR spectroscopy tracks the evolved gas products. This methodology provides insights into the subsurface microstructure evolution and related chemical reactions.

Summary: A model based on hydrodynamics and rheological behavior of semi-solid metals is proposed to estimate flow-induced microstructural segregation due to migration of externally solidified crystals (ESCs). By manipulating process parameters, such as solid fraction, cavity size, and filling velocity, it is possible to control such segregation. Experimental data and simulation results show good agreement, indicating the potential for optimization using a solid fraction-related rheological (SFR) model.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: An efficient phase inversion-impregnation approach is developed to fabricate BaO-decorated Ni8 mol% YSZ anode-supported tubular solid oxide fuel cells (SOFCs) with anti-coking properties. BaO nanoislands are successfully introduced inside the Ni-YSZ anode, leading to higher peak power densities and improved stability in methane fuel. Density functional theory calculations suggest that the loading of BaO nanoislands facilitates carbon elimination by capturing and dissociating H2O molecules to generate OH.

Summary: Li-CO2 batteries, which utilize CO2 and have a high energy density, are hindered in practical applications due to slow kinetics and safety hazards. This study introduces a stable and highly conductive ceramic-based solid electrolyte and a metal-organic framework catalyst to improve the safety and performance of Li-CO2 batteries. The optimized Li-CO2 cell shows outstanding specific capacity and cycle life, and the post-cycling analysis reveals the degradation mechanism of the electrodes. First-principles calculations based on density functional theory are also performed to understand the interactions between the catalyst and the host electrode. This research demonstrates the potential of MOF cathode catalyst for stable operation in Li-CO2 batteries.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
