Summary: Detailed monitoring of atomic-scale processes is crucial for understanding grain rotation in nanocrystalline metals. In this study, in situ atomic-resolution evidence reveals that the type of grain boundary plays a role in the atomic processes involved in grain rotation in nanocrystalline Pt. General GBs exhibit a combination of dislocation activities and atomic rearrangements, while tilt GBs mostly rely on dislocation activities. GB dislocation climb, glide, and reaction are often associated with Lomer-like dislocation formation and destruction.

Summary: We investigated the response of Cu-W nanocomposites prepared by physical vapor co-deposition to He implantation. Nuclear reaction analysis revealed that a significant portion of the implanted He escapes during the implantation process. Microstructural analysis of the nanocomposites suggested that the loss of He is likely due to its diffusion out of the material along phase and grain boundaries. Our findings suggest that solid-state interfaces, such as phase and grain boundaries, serve as shortcut diffusion pathways for He transport.

Summary: Fracture behaviors in perfect and twinned B4C crystals were studied via in situ TEM mechanical testing. It was found that cracks preferentially initiated at the twin boundaries (TBs) and propagated along them, resulting in the fracture of B4C. The theoretical calculations also showed a softening effect of TBs on B4C, with amorphous bands preferentially nucleated at the TBs. These findings clarify the atomic arrangement and the role of planar defects in the failure of B4C.

Summary: Ongoing research explores the potential of Sn atoms to form freestanding stanene and/or Sn patches in graphene pores. Experimental observations show novel single-atom thick 2D planar clusters/patches ranging from 1 to 8 atoms within the graphene pores, with patches of three or more atoms adopting star-like or close-packed structural configurations. Density functional theory calculations indicate deviations from experiment for 2D patches larger than five atoms due to interfacial interactions between graphene pore edges and Sn atoms, advancing the development of single-atom thick 2D elemental metal membranes.

Summary: An experimental and theoretical study of anatase grain boundaries fabricated by epitaxial growth on a bicrystalline substrate provides accurate atomic-scale models. The electronic structure in the vicinity of stoichiometric grain boundaries is relatively benign to device performance, but segregation of oxygen vacancies introduces barriers to electron transport. An intrinsically oxygen-deficient boundary exhibits charge trapping consistent with electron energy loss spectroscopy measurements.

Summary: During thermal annealing at 1425 degrees C, nominal electric field strengths of 50 V/mm and 150 V/mm were applied along the grain boundary planes of a near 45 degrees (100) twist grain boundary in SrTiO3. Interface expansions of approximately 0.8 nm were observed near the positive electrode for both field strengths. However, annealing at 50 V/mm resulted in a decrease in interface width to around 0.4 nm, while higher field strength caused decomposition of the boundary structure close to the negative electrode. The migration of oxygen due to the applied electric field leads to the observed alteration of grain boundary structures, and at high field strengths, the agglomeration of anion vacancies can cause grain boundary decomposition.

Summary: High radiation damage resistance is increasingly important for functional materials in harsh environments. Diamond cubic carbon, with its high radiation damage resistance, is a unique material that can be used in radiation environments. The interaction between point defects and interfaces, such as grain boundaries, increases resistance to radiation damage. Grain boundaries act as sinks for point defects and can be used to control the segregation of point defects, thereby preventing material degradation.

Summary: An accelerated irradiation method was used to study the effect of atomic displacement damage and helium implantation on the mechanical properties and microstructure of recrystallized and precipitation-hardened Inconel X750. The results showed that both atomic displacement damage and helium implantation led to increased yield and ultimate tensile strength, and decreased ductility. TEM examination revealed that the increased strength was attributed to point defect clusters for the proton irradiated material and He-stabilized cavities for the He-implanted material.

Summary: The study presents a method to derive well-conditioned continuum reaction-drift-diffusion equations from master equations on a discrete, periodic state space. This method is applicable to kinetic Monte Carlo models and discrete, periodic Markov chains, and involves modifying the drift term to accurately capture the kinetics. A generalized Bloch relation is employed to calculate the eigenspectrum of the master equation and a kinetic clustering algorithm is used to define a reduced, Markovian state space, eliminating fast modes that hinder time integration.

Summary: In this work, atomistic simulations were used to investigate the effect of vacancy diffusion on surface segregation during annealing of CuNi bimetallic alloys. The multi-timescale methods employed allowed for the observation of rare stochastic events that are not typically seen with standard molecular dynamics (MD), thus bridging the gap between computational and experimental timescales. These findings have implications for the experimental design of CuNi alloy surfaces with controlled segregation.

Summary: Formation of helium cavities in coarse-grained materials leads to hardening, while preferential cavity formation in grain boundaries in nanostructured metals causes softening. This study uses ultrafine-grained tungsten to investigate the effect of cavity evolution on mechanical response. Softening is observed at high implantation temperatures but low fluence, accompanied by cavity coalescence and reduction in hardness. Atomistic simulations reveal that softening is driven by stress concentrations and cooperative deformation processes in grain boundaries.

Summary: In this study, laboratory analysis was used to investigate the effect of mineral albedo on the midinfrared emissivity spectra of silicates under lunar environment conditions. The study found that darkening effects of space weathering would change the thermal gradient in heavily space weathered lunar regolith, as shown by the shifts in the Christiansen Feature maximum to longer wavelengths and decreasing spectral contrast with decreasing albedo. These findings suggest the need for further investigation into the effects of space weathering on the midinfrared spectra of airless bodies.

Summary: This work evaluated the kinetic parameters of the simultaneous reactions of HDS and HDN using CoMoP/Al2O3 and NiMoP/Al2O3 catalysts. Both power-law and Langmuir-Hinshelwood models provided good fits for the experimental data. The NiMoP catalyst showed higher hydrogenating power and stronger adsorption of nitrogen compounds compared to the CoMoP catalyst. Catalysts with higher hydrogenating power are more capable of performing both HDN and HDS reactions simultaneously.

Summary: This paper describes our recent efforts to demonstrate direct current sintering parameters suitable for mimicking near-identical microstructure to optimize reduced activation ferritic martensitic castable nanostructured alloy. The fabrication process is presented, and through a combination of computational thermodynamics, multimodal characterization, and mechanical testing, we confirm that sintering can be used to produce relevant castable nanostructured alloy (CNA). Our success in demonstrating the applicability of sintering to CNA fabrication opens up opportunities to fabricate functionally graded first wall tile structures or other complicated structures with demanding high-temperature performance, such as fusion high heat flux components.

Summary: This work investigates the formation of adjoining twin pairs (ATPs) at grain boundaries (GBs) in hexagonal close-packed (hcp) metals, focusing on the co-nucleation (CN) of pairs of deformation twins. A continuum defect mechanics model is proposed to study the energetic feasibility of CN of ATPs resulting from GB dislocation dissociation. The model reveals that CN is preferred over the nucleation of a single twin variant for low misorientation angle GBs. Further analysis considering GB character and twin system alignment suggests that CN events could be responsible for ATP formation even at low m' values.

Summary: This study investigates the behavior of electric-field induced antiferroelectric to ferroelectric (AFE-FE) phase transition and reveals the evolution of atomic displacement ordering as the cause for the transition behavior changing from sharp to diffuse. The novel semi-ordered configuration results from the competing interaction between long-range displacement modulation and compositional inhomogeneity, which leads to a diffuse AFE-FE transition while maintaining the switching field.

Summary: In this work, a physics-constrained neural network is used to predict grain-level responses in FCC material by incorporating crystal plasticity theory. The key feature, shear strain rate of slip system, is identified based on crystal plasticity and incorporated into the loss function as physical constitutive equations. The introduction of physics constraints accelerates the convergence of the neural network model and improves prediction accuracy, especially for small-scale datasets. Transfer learning is performed to capture complex in-plane deformation of crystals with any initial orientations, including cyclic loading and arbitrary non-monotonic loading.

Summary: This study attempts to address the gap in cooling rates between thin film deposition and bulk metallic glass (BMG) casting by correlating the glass-forming range (GFR) determined from combinatorial materials chips (CMCs) with the glass-forming ability (GFA) of BMG. The results show that the full-width at half maximum (FWHM) of the first sharp diffraction peak (FSDP) is a good indicator of BMG GFA, and strong positive correlations between FWHM and the critical casting diameter (Dmax) are observed in various BMG systems. Furthermore, the Pearson correlation coefficients suggest possible similarities in the GFA natures of certain BMG pairs.
