Summary: In this work, the periodic homogenization method is used to study a system of two diffusion equations coupled through heterogeneous chemical reactions. The upscaling is discussed based on the magnitude of the Damkohler number. For large Damkohler numbers, a new homogenized diffusion reaction model that couples chemical reaction and diffusion is obtained. The homogenized diffusion and co-diffusion tensors depend on the heterogeneous reaction rate coefficients. The relevance of this homogenized model is analyzed in relation to the magnitude of the Damkohler number. Numerical simulations using this homogenized model are conducted and compared to simulations at the pore scale.

Summary: Experimental and field studies have shown a significant difference in time scales between cleanup and contamination processes, with the hydrodynamic dispersion coefficient of cleanup being significantly larger than that of contamination. This nonuniqueness in dispersion coefficients is attributed to concentration-dependent diffusion during advection and diffusion, affecting both contamination and cleanup processes. The findings enhance our understanding of transport processes and improve the estimation of chemical transport time scales in geological and engineering systems.

Summary: This study investigates the dispersion process of reactive substances between parallel plates. The classical method of moments and eigenfunction expansion are used to calculate the moments up to fourth order, allowing the reflection of non-Gaussian properties. The study reveals strong non-Gaussian properties and asymmetric concentration distribution in the preasymptotic regime, which is extended by the presence of crossflow and wall adsorption.

Summary: This study established a three-dimensional biofilm model and evaluated the local fluid flow velocity and pollutant diffusion and reaction fluxes inside the biofilm. It was found that both uniform structured and previously proposed heterogeneous models overestimated the performance of biofilms in wastewater treatment. The survival strategies of living cells in biofilms were discussed, including exposure to fresh pollutants and the tendency to form small aggregates for reducing diffusional resistance.

Summary: Sodium can be used as a tracer for brine in reservoir formations, and this study investigates the diffusion behavior of sodium in both bulk solution and porous media using nuclear magnetic resonance (NMR) techniques. The results show that the diffusion rate of sodium decreases with increasing counter-ion size, with a greater effect observed at higher ionic strengths and in porous media. By combining numerical simulation and experimental methods, effective diffusion coefficients and matrix properties can be estimated.

Summary: Through large-scale molecular simulations and theoretical analysis, it was found that nanoparticles in polymer networks with semiflexible strands exhibit enhanced heterogeneous diffusion characterized by hopping dynamics, with the hopping energy barrier approximating to linear dependence on confinement parameters in the regime of moderate rigidity. This nonmonotonic feature is attributed to the competition between conformation entropy and bending energy regulated by chain rigidity.

Summary: Studied tracer dispersion in stratified porous media and found that the hydrodynamic coupling between two layers leads to the tensorial nature of dispersion and advection. The obtained dispersion tensor and advection are not symmetric unless both layers have similar thickness, porosity, and molecular diffusion. The study also revealed the presence of dispersion barrier, uphill dispersion and advection, and osmotic dispersion during tracer transport in stratified porous media.

Summary: In order to understand solute transportation and chemical inhomogeneity in directional columnar structures, anisotropic permeability law was incorporated into a volume-averaged columnar solidification model. Ten different permeability laws were used to investigate the impact of mushy zone permeability on macrosegregation and channel segregation in solidification. The results showed that permeability coefficient had significant effects on macrosegregation and channel segregation, with an uneven solute distribution resembling the columnar morphology. Anisotropic permeability laws predicted distinct and physically justified segregated channels, considering the effect of directional columnar structures on solute transportation.

Summary: Previous studies often oversimplified complex system models and their failure mechanisms did not reflect reality. In this study, we develop a new model of heterogeneous multi-coupled interdependent networks and analyze the change in the giant component of the network after attack, considering load redistribution. The results show that the heterogeneous multi-coupled interdependent network is more robust, and the existence of the giant component is influenced by the low robust sub-network, but it is also related to the stock of nodes.

Summary: This study used time-frequency spectral analysis of resting near-infrared spectroscopy (NIRS) signals to evaluate the regulation of peripheral microvascular perfusion in CKD patients. The findings suggest that CKD patients have impaired neurogenic and endothelial functions, which may be associated with increased sympathetic activity and reduced endothelial function in CKD.

Summary: This study examines the preventative and therapeutic effects of inhibiting mammalian target of rapamycin complex 1 (mTORC1) on abnormal retinal blood vessels in a rat model of retinopathy of prematurity (ROP). The results suggest that mTORC1 activation in proliferating endothelial cells contributes to the appearance and progression of ROP-like retinal blood vessels. Inhibition of mTORC1 may be a promising approach for selectively targeting abnormal retinal blood vessels in ROP.

Summary: In the study, the process of angiogenesis in adult regenerating tissue was investigated by grafting portions of the regenerating lung onto the chick chorioallantoic membrane. The results showed peri-graft angiogenesis, particularly in the cardiac lobe. Functional vascular connections were observed between the cardiac lobe and the chick chorioallantoic membrane vascular network. Elevated gene expression levels were found in the cardiac lobe compared to other lobes.
