Summary: Solid-state batteries have the potential to improve energy and power densities compared to conventional lithium-ion batteries. The composite cathode architecture, resulting from microstructural heterogeneity, poses a critical bottleneck for solid-state batteries. This study examines the inherent role of mesoscale interactions and how heterogeneities profoundly affect the spatio-temporal evolution of thermo-electrochemical dynamics, establishing solid-solid point contacts as mechanistic pain points for consideration in improving solid-state battery cathode architectures.

Summary: Ionic liquids show promise as designer solvents for multivalent electrolytes, with the ability to modulate solvate species interactions. Research on the molecular mechanisms and impact of ion clusters on electrolyte properties is lacking compared to ion pairs. Studies indicate that ion clusters can effectively suppress ion agglomeration in Mg electrolytes, leading to improved Coulombic efficiency for the reversible Mg deposition/stripping process. This highlights the importance of microstructural and dynamical heterogeneities in the rational design of enhanced multivalent electrolytes.

Summary: A continuous-time random walk (CTRW) reactive transport model is used to study the impact of physical heterogeneity on the effective reaction rates in porous media. The study shows that both the physical heterogeneity and transport conditions have an influence on the reaction rates, and a higher initial heterogeneity leads to a lower late-time reaction rate.

Summary: This brief review focuses on the recent progress in studies of the heterogeneous electrochemical behavior of various boron-doped materials, extending from zero-dimensional particles to three-dimensional surfaces. Boron-doped diamond exhibits large heterogeneities induced by factors like multifaceted crystallinity, uneven boron concentration, carbon ratio, surface terminations, and grain size distribution. Nanostructured diamond surfaces allow for high areas and large aspect ratios, showing highly heterogeneous charge-transfer performance for various applications.

Summary: This study investigates the effects of acid solution injection on chalk core samples and reveals that it increases the permeability of the rock samples and creates preferential conduits. The initial structural properties play a crucial role in determining the dissolution regime, with homogeneous systems showing direct correlation between dissolution rate and flow rate/acid concentration, while heterogeneous systems are controlled by pre-existing large-scale structural heterogeneities and micro-scale heterogeneities.

Summary: The study explores the impact of sub-scale chemical gradients on reaction kinetics using localized pulses of solute reacting with a solid or a dissolved species in excess as a case study. The combination of diffusion and reaction leads to effective kinetics that differ quantitatively and qualitatively from batch kinetics, resulting in a variety of reaction dynamics depending on the nonlinearity of the local kinetics. The findings offer new insights into interpreting imperfectly mixed lab experiments and integrating sub-scale concentration gradients in reactive transport models for field systems.

Summary: The study found that biphilic surfaces can be used for controlled dropwise condensation and liquid transport. The surface temperature and subcooling greatly affect their performance. Compared to uniform superhydrophobic surfaces, biphilic surfaces have faster condensation dynamics, but most droplets remain immobile within a few hours. This provides guidance for applications such as water collection, heat transfer, and separation processes.

Summary: Isotopic information from 81 snowpits in a large Colorado watershed was analyzed to understand the variability of snowpack and snowmelt. The study found that snowfall isotopic inputs and aspect were the primary factors affecting snowpack variability, while sublimation increased at lower elevations and during periods of high temperature and solar radiation. Additionally, post-depositional fractionation and isotopic homogenization were observed in the snowpack, with snowmelt becoming isotopically enriched over time.

Summary: A hydrologic and snowpack stable water isotope model is used to assess the controls on isotopic inputs in a mountainous basin. The study finds that the most depleted isotopic conditions occur in the upper subalpine where snow accumulation is high and rainfall is low. The isotopic inputs in meltwater are determined by the amount, phase, and isotopic mass of precipitation during the ablation period. Evaporative loss from the snowpack has the greatest effect on d-excess in snowmelt above treeline and in regions with low vegetation shading.

Summary: Unprecedented climate change and anthropogenic activities have led to increasing ecohydrological problems, prompting the development of large-scale hydrologic modeling for solutions. However, scientific progress in tracking water parcels at large-scale with high spatiotemporal resolutions is lacking due to the absence of powerful modeling tools. In this study, a parallel framework for the particle tracking model EcoSLIM is demonstrated, showing significant speedup and excellent parallel performance. This parallel framework can be applied to other particle tracking models and is a promising tool for accelerating our understanding of the terrestrial water cycle and upscaling subsurface hydrology to Earth System Models.

Summary: This study develops a purely data-driven approach to estimate water table depth (WTD) at continental scale, using a random forest (RF) model. The RF model provides reasonable estimates of WTD over most of the contiguous United States (CONUS), offering an alternative to physics-based modeling for large-scale freshwater resources. The study demonstrates that the RF model can be transferred to other regions with similar hydrologic regimes and limited observations.

Summary: This study explores the impact of precipitation, shortwave radiation, and wind speed on the water cycle of a small alpine catchment. High-resolution simulations show that distributed precipitation and shortwave radiation have significant impacts, while distributed wind speed has a smaller effect. This suggests that slope- and aspect-based meteorological distribution can improve the spatio-temporal representation of snow cover and evapotranspiration in complex mountain terrain.

Summary: Physical aquifer models are effective teaching tools for hydrology education, but they have limitations like high cost and static configuration. To overcome these limitations, an interactive computer simulation called ParFlow Sandtank has been developed. This tool allows users to learn hydrologic concepts and explore various factors affecting environmental systems, with features like model parameter adjustments and visualization of outputs. It has been widely used in educational settings and can be scaled-up for greater accessibility.
