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: Infrared devices are increasingly used in various applications. This paper introduces a novel dispersive spectrometer that has high-throughput and decoupled spectral resolution. The proposed spectrometer utilizes a two-stage Hadamard transform encoding process to increase the signal-to-noise ratio. With a single-pixel detector, the system can be easily implemented in other desired wavelengths. Additionally, a method is developed to remove the need for uniform illumination and improve the ease of device design for in situ measurement.

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 evaluates the utility of near infrared (NIR) spectroscopy in quantitatively analyzing the moisture content in cellulose. It is the first statistical-based work to examine the relationship between wavenumber/absorbance and moisture content. The research describes the variations in the X- and Y-coordinates of 9 absorption bands plotted as a function of water amount established with Karl-Fischer titration. Simple linear, semilogarithmic, and power models were investigated, with the power model successfully describing the changes in intensity of the peak situated from 5400 to 5000 cm-1.

Summary: This study investigated the effects of epoxy resin contents on the performance of hot-mix epoxy asphalt and found a cost-effective proportion. Results showed that when the epoxy resin content exceeds or equals 40%, the mechanical properties of epoxy asphalt meet the requirements. Increased epoxy resin content also leads to a higher viscosity-increasing rate, especially at high temperatures. Additionally, certain wavenumbers in the infrared spectrum of epoxy asphalt demonstrate positive correlations with epoxy resin contents. Fluorescence microscopy tests revealed agglomeration of epoxy resin particles and the formation of a cross-linked spatial structure when the epoxy resin content exceeds or equals 40 wt%.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
