Summary: This paper presents a high-order gas-kinetic ALE scheme for three-dimensional flows, utilizing the WENO scheme for spatial reconstruction and a two-stage fourth-order discretization for temporal evolution. The scheme carefully addresses mesh distortion and non-coplanar vertexes by selecting candidate stencils and designing topologically independent linear weights, while using bilinear interpolation to preserve the geometric conservation law in surface integrals for flux transport. The accuracy, robustness, and preservation of geometric conservation law of the scheme are evaluated through numerical examples.

Summary: We propose a set of novel closures for high-energy-density physics simulations with non-conformal meshes of materials, which affect thermal radiation transport (TRT). The closures work for any number of materials, both grey and multigroup energy discretizations, and any angular discretization (Sn, IMC, or diffusion). Our closures allow each species (ion and electron) of each material to have its own temperature, density, and internal energy, but use a single radiation distribution that interacts with all materials within the cell. The closures maintain energy conservation, have no additional computational cost in the TRT solve, are compatible with single-material TRT solvers, and do not assume temperature equilibrium.

Summary: The behaviour of a weakly-compressible SPH scheme obtained by rewriting the Navier-Stokes equations in an arbitrary Lagrangian-Eulerian (ALE) format is studied. The proposed model is expressed in terms of primitive variables (density and velocity) and is written using the standard differential formulations of weakly-compressible SPH schemes. The scheme can be stabilized by including appropriate diffusion terms in both the equations of density and mass.

Summary: Active sorting via acoustic and electric fields has potential in microscale separation activities, with the combination of these techniques taking advantage of multiple force mechanisms simultaneously. The concurrent application of dielectrophoretic (DEP) and acousto-phoretic forces has been shown to decrease the critical diameter at which particles can be separated, allowing for efficient sorting of subpopulations of extracellular vesicles. Using a combined acoustic/electric approach, exosome purification with high purity and recovery rates has been demonstrated.

Summary: Co-encapsulation of bead carriers and biological cells in microfluidics has become a powerful technique for various biological assays in single-cell genomics and drug screening. However, current co-encapsulation approaches limit the effective throughput due to a trade-off between cell/bead pairing rate and probability of multiple cells in individual droplets. The DUPLETS system is reported to overcome this problem by differentiating the encapsulated content in individual droplets and sorting out targeted droplets via a combined screening of mechanical and electrical characteristics.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
