Summary: In this study, the diffusion coefficient of an active tracer in a crowded environment with hardcore interactions is calculated. A closure approximation method is proposed to accurately determine the diffusion coefficient for an arbitrary density of crowders in the system, capturing non-equilibrium effects. The approach also allows the characterization of environment perturbations induced by the movement of the active tracer. The asymptotic regimes of low and high densities are considered to obtain explicit expressions for the diffusion coefficient.

Summary: This study highlights the significant impact of particle preferred orientation on water dynamics in clayey media, demonstrating differences in water diffusion properties between swelling and non-swelling clay minerals, and the influence of interlayer porosity on water diffusion. The results also show that anisotropy in water diffusion can be directly predicted based on the degree of particles' preferred orientation, regardless of the total or distribution of different types of porosities.

Summary: A novel poly(phenazine-alt-pyromellitic anhydride) (PPPA) has been synthesized as a promising cathode material in organic zinc-ion batteries. The PPPA cathode exhibits a reversible Zn2+-coordination mechanism and an ultrahigh Zn2+ diffusion coefficient, which is the highest among all organic cathode materials for zinc-ion batteries. The extended pi-conjugated plane in PPPA sample contributes to a significant reduction in energy gap, promoting intramolecular electron transfer during charge/discharge process.

Summary: Diffusion behavior in the CoCrFeMnNi high-entropy alloy is investigated using an augmented tracer/interdiffusion couple approach. A consistent composition-dependent diffusion database is established, and a pair-diffusion model is used to describe the tracer diffusion and chemical concentration profiles. The uphill diffusion of Co observed in the experiment cannot be explained by existing kinetic and thermodynamic databases, and the vacancy wind effect is found to have a strong influence on intrinsic cross diffusion coefficients.

Summary: The effect of local photo-triggered heat release on the motion of organic nanoparticles is investigated. It is found that the nanoparticles undergo acceleration upon light absorption and their motion shows a strong dependency on the irradiation intensity. The analysis also reveals that the effective temperature increase due to irradiation is much larger than expected. In addition, the nanoparticles exhibit a fractional Brownian motion in more intense irradiation regime.

Summary: Artificial tracer testing is an effective method to identify fluid flow pathways and characterize subsurface hydrological properties. Synthetic DNA tracers with varying lengths were used in laboratory experiments to investigate their transport behavior, showing that DNA length and adsorption have notable effects on DNA tracer transport. The effects of DNA length on peak arrival time and tracer dispersion were not significantly different in a given porous medium, but showed reversed trends in different porous media, likely due to the different likelihoods for longer DNA to have multisegment attachment during transport.

Summary: Replacing carbon black and silica with organic fillers can decrease the weight of polymer nanocomposites. Soft nanoparticles (SNPs), produced in large quantities through microemulsion polymerization, can be customized in terms of elasticity and diameter. This study investigates the linear viscoelasticity of all-polystyrene nanocomposites filled with different molecular weights of matrix chains. The results show that the second plateau is observed with semi-rigid SNPs if the weight percentage of SNPs is above a critical value, while polymer nanocomposites filled with soft SNPs do not exhibit this plateau.

Summary: The diffusion behavior of Al and Cu in the Cu(Al) solid solution phase was investigated, and it was found that the diffusion coefficient of Al was higher than that of Cu. The thermodynamic factor for the Cu(Al) phase was calculated, and different activation energies were observed for intrinsic and tracer diffusion for Al and Cu. The correlation factors suggested a low concentration of vacancies involved in the diffusion process and a higher jump ratio for Al compared to Cu.

Summary: Living systems contain active particles that can enhance the diffusion of passive particles through their active motion. The density and activity of active particles affect the passive tracer particle diffusion. Additionally, clustering of active particles can suppress the enhanced diffusion of passive particles.

Summary: Through rational design and engineering, we have developed a soft prosthetic electronic skin that mimics the sensory feedback and mechanical properties of natural skin. It is capable of multimodal perception, neuromorphic pulse-train signal generation, and closed-loop actuation. Our e-skin has achieved low subthreshold swing, low operation voltage, low power consumption, and medium-scale circuit integration complexity for stretchable organic devices, thanks to a trilayer, high-permittivity elastomeric dielectric.

Summary: This study explores the potential of magnetothermal responsiveness and covalent adaptable networks in liquid crystalline elastomers to realize versatile morphing modes and local magnetic control. Various magneto-actuated contraction-derived motions can be achieved, reprogrammed, and seamlessly assembled. The systems also exhibit favorable performances including stepwise magnetic controllability, multiresponsiveness, self-healing, and remolding ability.

Summary: This study aimed to mathematically model the release behavior of polymer-drug conjugates and proposed a diffusion model suitable for macromolecular drugs. The results showed that hydrogels have a heterogeneous structure, and the release of macromolecules is affected by diffusion in different regions. Additionally, this study demonstrated the applicability of a biphasic model in designing hydrogel systems for precision drug release.

Summary: This study analyzes the diffusion of particles on a two-dimensional square lattice using the excess chemical potential to represent the interaction between particles. A general expression for transition rates between neighboring cells is derived, and the approximate expression for the correlation factor representing memory effects is obtained through analyzing the joint probability of having given numbers of particles at different sites.

Summary: A new area of sustainable energy and environmental research focuses on developing novel electrolytes to enhance the solubility of target species and improve reaction performance, particularly in flow batteries and CO2 conversion. Liquid-like nanoparticle organic hybrid materials (NOHMs) show promise for electrolyte applications due to their enhanced conductivity, although high viscosity is a challenge. This study investigated the impact of different secondary fluids on the transport behaviors of NOHMs, with findings on how secondary fluids affect transport properties and the conformation of polymer in NOHMs.
