Summary: The soil system is a dynamic component of the earth, and aggregate stability is crucial for soil quality and ecosystem services. This study found that the impact of clay, soil organic carbon, aluminum, and iron oxides on aggregate stability in tropical and subtropical soils is controversial, and the stability of aggregates varies depending on different breakdown mechanisms. Soil organic carbon and soil texture do not play a significant role in aggregate stability, while silicon oxides and iron oxides increase resistance to breakdown, and aluminum oxides decrease stability. The recommended methods for evaluating (sub)tropical soil aggregate stability are rainfall simulation and wet sieving.

Summary: Due to intensive cultivation, paddy fields in southeastern China are experiencing varying degrees of degradation and loss of soil organic carbon (SOC), leading to potential threats to the industry's sustainability. This study examined soil nutrients, stoichiometric ratios, and carbon pool management index (CPMI) in degraded paddy fields. The results showed that severe degradation led to significant decreases in concentrations of total nitrogen (N), labile organic carbon (C), total phosphorus (P), and available P, while iron (Fe) and available N tended to increase. The study also found that soil pH, Fe3+, sand, and electrical conductivity significantly influenced soil stoichiometric ratio and nutrients. Overall, paddy degradation resulted in greater loss of soil carbon and nitrogen than phosphorus, highlighting the need for proper agricultural practices and reduced cultivation of exhaustive crops to mitigate further soil degradation and restore soil fertility and carbon sequestration.

Summary: Carbon sequestration in soil has been extensively studied in agroecosystems through increasing organic carbon inputs and reducing soil organic carbon degradation processes. However, the influence of shallow water table on mineral soils, despite the importance of soil moisture in modifying the carbon cycle, is not well understood. This study examines the effects of shallow water table on carbon balance components in mineral soils and finds that a negative carbon balance was observed under all treatments. The study also highlights the interaction between shallow water table and organic carbon type, which is crucial for carbon balance in mineral soils.

Summary: Rhizosheaths are aggregated, sheath-like soils that physically adhere to root surface, and they have distinct soil organic carbon (SOC) signatures from rhizosphere soils of non-rhizosheath forming plants. The molecular characteristics of rhizosheath SOC, including more root inputs of labile substrates and relatively recalcitrant compounds, as well as its temporal dynamics, suggest a critical role of rhizosheath in shaping the rhizosphere microenvironment and regulating SOC cycling.

Summary: Liquefying halogen or inter-halogen compounds is crucial for achieving high reversibility in lithium halide cathodes. This can be done using interhalogen compounds with different electronegativity or by lowering the temperature. By demonstrating reversible LiCl conversion-intercalation chemistry in organic electrolytes, high reversible specific capacity is achieved in LiCl-LiBr-graphite cathodes at a lower cost than transition metal oxide cathodes.

Summary: Using pulsed laser deposition, a EuO1-x film was deposited on a Si(001) substrate with a MgO buffer, and compared to a heterostructure with an additional BaTi2O5 film on top of the EuO1-x surface. XRD analysis showed that the films had a preferred EuO(111) orientation and the presence of EuSi2, suggesting diffusion of Si or Eu across the MgO buffer layer. The EuO1-x films exhibited a ferromagnetic signature and temperature-dependent exchange bias, while the BaTi2O5 films showed an antiferromagnetic behavior, indicating an origin at the BaTi2O5/EuO1-x interface.

Summary: CO2 electrochemical reduction (CO2ER) is a promising technology for converting CO2 into useful chemicals and fuels, reducing greenhouse gas emissions. Cu nanoparticles-based catalysts are an excellent choice for CO2ER due to their high conductivity and catalytic activity. This study used STXM and spectro-ptychography to investigate the chemical and electronic structural changes of CuAg nanocatalysts during CO2ER. The observed self-aggregation and oxidation of Cu species provide insights into the loss of catalytic activity in CuAg nanocatalysts after CO2ER.

Summary: Understanding the spatial variability of factors that influence crop yield is crucial for site-specific management. This study evaluated the apparent soil electrical conductivity (ECa) in two fields and assessed whether the delimitation of management zones (MZs) based on ECa could identify regions with different soil densities (Sd). The results showed that MZs with higher ECa values also had higher Sd values, and the proposed ECa could detect in-field differences in Sd regardless of soil texture. Further studies are needed to confirm the efficiency of ECa in detecting soil bulk density at different depths.

Summary: This study developed a satellite-based data fusion approach to map crop rotation at field-scale and analyze the effects of environmental factors on crop yields in southern Brazil. The results showed that continuous soybean planting and one-year soybean with one-year corn rotation were the most common crop rotation patterns in the region. The study also found that crop rotation had significant effects on soybean yields, with variations depending on the regions and years of rotation. Furthermore, climate conditions and soil organic carbon were identified as important factors influencing crop rotation. This study provides the first crop rotation map for the state of Rio Grande do Sul and serves as a foundation for similar databases in other states and countries.

Summary: Li-ion battery electrodes exhibit a resistance increase during high-rate lithiation, which is poorly understood. Li transfer kinetics at the surface determines the hysteresis. Surface and bulk phase separation strongly depends on the direction and magnitude of the current. Dynamical asymmetry between lithiation and delithiation is attributed to autoinhibitory Li-rich and autocatalytic Li-poor domains.
