Summary: The kinetics of transient coarsening co-controlled by interface and matrix diffusion is studied in a new framework developed in the Lifshitz-Slyozov-Wagner space. The time for transient coarsening is found to change non-monotonically with the width and tail length of the initial distribution. A unique attractor state for the steady stage is identified, and the numerical origin of 'quasi-steady' distributions is revealed. The increase in volume fraction shortens the transient stage dominated by single mechanism but delays the transition to the diffusion-controlled stage.

Summary: The roles of curvature and stochastic effects in grain growth kinetics have been a long-standing question in theoretical analysis. This study introduces a thermodynamic dissipation-based framework that incorporates contributions from microstructure entropy and phenomenological grain topological energy to capture the stochasticity and spatial correlations in grain growth. The correlations between previous mean-field and stochastic theories are revealed and further validated using the 3-D Aboav-Weaire relationship.

Summary: It is confirmed in this study that the evolution of a non-equilibrium system corresponds to the constrained maximum of dissipation, while a system in a steady state minimizes dissipation. Additionally, the maximal dissipation generally decreases to its minimum value when the system approaches its steady state. Although these results agree with previous literature, the problem is still not fully clarified.

Summary: The adsorption of diclofenac (DCF), a common pharmaceutical pollutant, on Fe2O3-pillared montmorillonites (Fe-PMts) was studied. Fe-PMts were synthesized by intercalation of natural montmorillonite with iron polyoxocations. The pillaring process significantly increased the specific surface area and sorption capacity of the clay. The pH, sorbent content, DCF concentration, and temperature were found to be the main factors affecting DCF adsorption. The kinetic data and adsorption isotherm were analyzed using various models, and the results showed that the adsorption followed pseudo-second order kinetics and Langmuir isotherm. The thermodynamic parameters indicated that the adsorption of DCF on Fe-PMt was spontaneous and exothermic. Fe-PMt was proven to be an effective and environmentally friendly sorbent for DCF removal in pharmaceutical wastewater treatment.

Summary: Ionic liquids (ILs) have strong interactions with various solid surfaces, making them useful in lubrication, energy storage and conversion, and other applications. However, due to the vast number of potential ILs, finding the appropriate ILs for specific solid interfaces with desired properties is challenging. This study proposes a new method of deriving interaction parameters directly from experimental data obtained through colloid probe atomic force microscopy (CP-AFM), and tests the reliability of these parameters through molecular dynamics simulations.

Summary: Diffusion is crucial in regulating the microstructure and properties of metallic materials. However, the understanding of how microalloying affects diffusion kinetics in gold bonding materials is still incomplete, posing a threat to the reliability of microelectronic devices in the era of big data. Through theoretical computations, we demonstrate that trace rare earth (RE) microalloying can control diffusion at high temperatures in gold bonding materials. This finding offers insights into a rational microalloying strategy to improve the heat resistance and service lifetime of microelectronics packaging materials.

Summary: Classical thermodynamics focuses on quantifying the efficiency of thermodynamic engines and the challenge lies in estimating the upper limit of power transmission. Recent insights from stochastic models provide a new perspective for practice, indicating that power optimization can be achieved through stochastic control. By utilizing the framework of stochastic thermodynamics, bounds on the maximal power that can be drawn by cycling an overdamped ensemble of particles via a time-varying potential can be derived.

Summary: The need to reduce the lifecycle greenhouse gas emissions of fuels and lubricants has increased attention on hydroisomerization processes. By recognizing the individual alkane hydrocracking pathways, changes to the alkane hydroisomerization and hydrocracking networks can be determined based on catalyst pore topology. Spacious pores allow access to both kinetically favored and thermodynamically favored hydrocracking pathways, while narrower pores enhance isomerization by slowing down access to certain pathways and limiting hydrocracking to specific isomers.

Summary: Model-free data-driven computational mechanics replaces phenomenological constitutive functions with numerical simulations based on data sets. This method works well for non-linear elastic problems, but faces challenges with history-dependent materials. Recent research has addressed this issue by including local histories in the data set, but the need for models of specific internal variable evolution remains. Thus, a mixed formulation of classical and data-driven modeling is being developed.

Summary: This study proposes a novel porous breakwater based on triply periodic minimal surface (TPMS) cellular structure, and investigates its mechanical and hydrodynamic characteristics through experimental and numerical simulations. The results show that the Gyroid cellular structure exhibits better mechanical performance and its porosity affects the maximum load significantly. Computational fluid dynamics simulations reveal that the proposed breakwater can effectively reduce the energy of incident waves, and the porosity variation also influences wave transmission coefficients and wave-induced forces on the structure.

Summary: A variational model of pressure-dependent plasticity with a time-incremental setting is proposed. The dissipation potential is formulated in a novel manner to ensure variationally consistent condensed energy. For a one-dimensional model problem, an explicit expression for the quasiconvex envelope is derived, which is essentially independent of the original pressure-dependent yield surface. The model can be extended to higher dimensions empirically. Numerical simulation demonstrates well-posed behavior and mesh-independent results.

Summary: Waveform inversion is utilized to determine an optimal model for the velocity field of a ground structure by establishing a realistic forward computer model using a suitable numerical approach and solving the forward problem in the frequency domain with higher-order finite elements. The velocity field is inverted over specific frequencies to reduce computational costs and the nonlinearity of the inverse problem. Results are presented for different frequency sets, source and receiver locations in a two-dimensional model, and attenuation effects are also investigated, along with blind tests on unknown synthetic models to simulate realistic scenarios. Finally, the inversion results in a three-dimensional space are illustrated.

Summary: Elemental powders of Al, Ti, Sc, and Zr are blended and processed via laser powder-bed fusion to create binary and ternary alloys. The microstructural analysis and mechanical testing show that the addition of Ti results in the formation of primary precipitates, while the addition of Sc and Zr leads to the formation of fine grain bands. The Al-0.25Ti-0.25Zr alloy exhibits comparable strain rates to Al-0.5Zr at low stresses, but significantly higher strain rates at higher stresses during compressive creep testing. Finite element modeling suggests that the connectivity of coarse and fine grain regions is a critical factor affecting the creep resistance of the alloys.

Summary: Inverse temperature dependences of the detwinning stress were observed in face-centered cubic deformation twins in Cu-8at.%Al alloy. The detwinning stress increased with temperature when the pi detwinning mode was involved, but decreased when the pi/3 mode was involved. The dual effect of temperature on the detwinning stress was due to the reduction of internal stresses pre-existing within the deformation twins. The complete reduction of internal stresses at about 530 degrees C led to the equivalence of the critical stresses of different detwinning modes and a decrease in the yield stress anisotropy of the twin/matrix structure.

Summary: The elastic-plastic transition in magnesium alloy Mg-4.5Zn exhibits bursts of deformation, which are characterized by sudden changes in grain orientation. These bursts occur in a coordinated manner among nearby grains, with the highest burst rate observed at the onset of full plasticity. The most significant burst events are associated with twinning, supported by the observation of twinned structures using electron microscopy. The bursts are often preceded and followed by a stasis in peak movement, indicating a certain "birth size" for twins upon formation and subsequent growth at a later stage.
