Summary: Soil salinity has a significant impact on agricultural production, especially in low-lying coastal areas where saltwater intrusion is a growing concern. Monitoring salinity is challenging due to the influence of soil moisture on the soil's spectral signature. The study found that Fourier-transform infrared spectroscopy can be used to map salt-affected soils, particularly in inaccessible areas. Advancements in thermal satellite sensors may provide possibilities for monitoring soil salinity in the future.

Summary: Soil biogeochemistry is interconnected with the redox cycling of iron and manganese, where manganese oxides serve as electron acceptors and might be reduced by organic substances as electron donors. In this study, we investigated the impact of low-molecular-weight organic acids (LMWOA) on the transformation of birnessite. Our findings suggest that the reductive transformation of birnessite into more stable forms of manganese oxides is facilitated by the oxidation of LMWOA, which serves as electron donors. This process plays a critical role in controlling the abundance of LMWOA in natural systems.

Summary: Accelerating permafrost thaw increases organic matter availability in high-latitude ecosystems. The chemical composition of permafrost-derived organic matter influences microbial metabolic efficiency, which can determine the Arctic's role as a carbon sink or a source of greenhouse gases. This study investigated shifts in soil and dissolved organic matter chemistry during a thaw experiment, and found that permafrost depth and enzyme activities correlated with changes in organic matter chemistry. Understanding these patterns can help improve projections of Arctic carbon storage during global change.

Summary: This study focuses on the three-dimensional compositional mapping of Li in Li-doped ZnO films using atom probe tomography, and confirms the phase formation of the films through spectroscopic analyses. Scanning electron microscopy was used to determine the structure evolution of the films, while EDX and XPS were employed to estimate the stoichiometric ratio of Zn and O and probe their chemical state. APT was then used to quantitatively estimate and map the distribution of Li, Zn, and O on the film surface.

Summary: Fuel cells and rechargeable batteries have achieved great success as advanced electrochemical energy conversion and storage techniques. With the increasing demand for energy in modern societies, there is a need for EECS devices with high efficiency and enhanced performance. The rational design of catalysts, electrode materials, and electrode/electrolyte interfaces based on a deep understanding of electrochemical redox reactions is crucial. In situ techniques such as Raman, FTIR, and XRD spectroscopy can provide valuable information on the dynamic redox reaction processes and help identify intermediates, leading to a better understanding of mechanisms and the development of novel EECS systems.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
