Summary: The assembly and jamming of magnetic nanoparticles at liquid-liquid interfaces can create ferromagnetic liquid droplets with controllable magnetization and response to external stimuli. Remanent magnetization comes from jammed magnetic NPs at the interface and dispersed NPs coupled to it magnetostatically, even at low concentrations. Mixing nonmagnetic and magnetic NPs results in the formation of FMLDs, enabling structured liquids with heterogeneous surfaces.

Summary: By using the interactions between nanoparticles and polymeric ligands, nanoparticle surfactants can be generated at the liquid-liquid interface, increasing the binding energy. Through a simplified model, it is found that competitive ligands can reduce the binding energy, leading to the dissociation and disassembly of the surfactants at the interface and allowing the construction of responsive and reconfigurable all-liquid systems.

Summary: In this Letter, a new phenomenon is reported where a droplet can undergo multi-lobed rotation by controlling only its volume without the use of external devices, which is different from previous studies. This phenomenon is based on the interfacial reaction that causes the droplet rotation effect. In this system, the angular velocity and number of lobes have an inversely linear relationship with the droplet radius. By controlling the droplet volume, it can be manipulated to form four-, three-, and two-lobed shapes. Simple models are proposed to explain this phenomenon. The results support the theory proposed by Scriven and Brown.

Summary: The uneven distribution of biochemical reactions in space and time leads to the diversity of biological systems. Liquid-liquid phase separation (LLPS) is a remarkable example of fine regulation of these reactions by the microenvironment. With a sensor based on gold nanoparticles, we demonstrate that interfacial factors in natural biological environments and sensors exhibit similar properties, repelling molecules outside the interface and adjusting DNA conformation within the interface to produce unique dynamics.

Summary: All-aqueous microdroplets produced by liquid-liquid phase separation have been used as promising models of artificial cells and offer new methods for solvent-free encapsulation of fragile solutes. In this study, stable and impermeable water-in-water emulsions were constructed by the interfacial self-assembly of mixed sodium oleate/1-decanol bilayers on dextran-rich droplets. The lipid-based membrane was shown to be impermeable to oligonucleotides, proteins, and a low molecular weight dye.

Summary: The importance of colloidal self-assembly in scientific and technological advances is investigated. The self-assembly of colloids at fluidic interfaces that mediate elastic interactions is studied, and the dominant forces in the assembly of nanoparticles are found to be the electric double layer forces and the elastic forces caused by liquid crystal strain. The study also reveals the role of ion partitioning at the liquid crystal-water interfaces in the formation of assemblies. The findings have important implications for applications in sensors, microelectronics, and photonics.

Summary: This study is the first to report the uptake of nanoparticles (NPs) into liquid-liquid phase separation (LLPS) droplets in living cells. Fluorescent imaging was used to visualize the uptake of Nile red loaded polystyrene NPs (NR-PSt NPs) into LLPS droplets consisting of adenosine triphosphate (ATP) and poly-L-lysine (PLL). The results showed that the LLPS droplets exhibited a rapid uptake behavior of NPs. Moreover, temperature changes and ionic strength significantly affected the NP uptake behavior and stability of the LLPS droplets.

Summary: The study demonstrates that applying a negative voltage to the interface between liquid alloys and aqueous electrolytes can rapidly liberate bismuth nanostructures, with the oxidation state, morphology, and crystal structure of the expelled bismuth being controllable by adjusting a set of conditions; addition of ascorbic acid can prevent oxidation and produce bismuth metal nanoparticles. Molecular dynamics simulations help elucidate the rapid phase separation at the interface, potentially opening up new pathways for refining metals and producing nanomaterials using alloys as reaction media.

Summary: In this paper, a computational origami design method based on the nonlinear analysis of loaded thin sheets and topology optimization is proposed. By introducing a continuous crease indicator as the design variable and penalizing it with power functions, the method is able to establish the mapping relationships between the crease indicator and hinge properties. By minimizing the structural strain energy with a crease length constraint, the thin sheet can evolve into an origami structure with an optimized crease pattern. Two examples are provided to illustrate the effectiveness and feasibility of the method.

Summary: In this study, Cr2AlC single crystal samples were irradiated and their mechanical properties were measured. The results showed that new slip traces were activated after irradiation, and both the yield strength and Young's modulus decreased gradually with increasing irradiation doses, indicating a significant radiation softening effect. This softening effect may be the result of irradiation-induced vacancies, supported by DFT calculations. These findings suggest that MAX phases like Cr2AlC have excellent irradiation tolerance regarding mechanical properties and are promising candidate materials for advanced nuclear systems.

Summary: In this study, a theoretical framework is established to solve the interfacial coupled flow problem on a microstructured surface with slip boundary. By finding integral relation between the slip velocity and the slip velocity gradient, we solve the slip problem under the low-Reynolds-number limit. It is found that a small viscosity ratio, large fluid interfacial fraction, or large depth-to-width ratio of a groove can result in a large vorticity flux in the groove, leading to a large slip length. Therefore, we propose a method to enhance the slippage by introducing a jet flow in the grooves, which is verified by our theory. This study provides a new method for theoretically solving the coupled flow problem and can be extended to cases of high-speed flow.

Summary: Helium migration is a crucial mechanism in the embrittlement of irradiated metallic materials, impacting their reliability. This study presents a theoretical model that combines crystal plasticity and helium diffusion to explain the bidirectional dislocation-induced helium transport. Simulation results demonstrate that dislocation motion significantly affects helium migration in austenitic stainless steel, resulting in enriched helium concentration at grain boundaries and a higher risk of intergranular fracture. Additionally, the study reveals the influence of temperature and irradiation defects on helium concentration at grain boundaries by regulating intragranular helium distribution, providing insights into failure mechanisms of irradiated metallic materials.

Summary: Millifluidics, a revolutionary concept in chemical processing and engineering, enables the manipulation of liquid flow in millimeter sized channels. However, the rigid design of solid channels restricts their flexibility and prevents contact with the external environment. On the other hand, all-liquid constructs lack the flexibility of design and are immersed in a liquid environment. This study presents a solution by encapsulating liquids in a hydrophobic powder in air, allowing for flexibility and adaptability in design, as well as the ability to reconfigure, graft, and segment constructs.

Summary: Porous materials with nanometer-scale pores have important applications as nanoporous membranes. In this study, ABA triblock copolymers were used as precursors to produce nanoporous polymeric membranes (NPMs) in thin film form by degrading the end blocks. Polycyclooctene (PCOE) NPMs with tunable pore sizes were successfully prepared using solvent casting technique. Oxygen plasma etching was employed to improve the surface porosity and hydrophilicity of the membranes. This study provides a straightforward method to produce tough NPMs with high porosity and hydrophilic surface properties.
