Evolution of thermal conductivity for sand-clay composite under one-dimensional compression

-


 

The evolution of thermal conductivity in sand-clay composites under one-dimensional compression is a critical subject in geotechnical and environmental engineering. As pressure increases, the rearrangement of soil particles, reduction in porosity, and redistribution of moisture content significantly influence the heat transfer capabilities of the composite. Initially, thermal conductivity tends to increase with compression due to improved particle contact and reduced air voids, which are poor conductors of heat. However, the rate of increase may vary depending on factors such as clay content, water saturation level, and grain size distribution. Understanding these variations is essential for designing effective underground thermal energy storage systems, evaluating soil behavior under load, and predicting heat transfer in layered soils in various engineering applications.

Biochar-influenced solubilization and mineralization mechanisms of phosphorus in saline-sodic soils

-
      The application of biochar in saline-sodic soils plays a crucial role in enhancing phosphorus (P) availability through improved solubilization and mineralization mechanisms. Biochar, due to its high surface area, porous structure, and functional groups, can adsorb excess sodium and reduce soil pH, creating favorable conditions for phosphorus dynamics. It enhances microbial activity and supports phosphorus-solubilizing bacteria and fungi, which convert insoluble phosphorus compounds into bioavailable forms. Moreover, biochar can interact with organic matter and soil minerals to release occluded phosphorus and reduce fixation by calcium, magnesium, and sodium ions. This dual function of improving soil structure and stimulating biochemical processes leads to increased phosphorus uptake by plants, especially in nutrient-deficient and saline-affected environments. #Biochar #PhosphorusSolubilization #PhosphorusMineralization #SalineSodicSoil #SoilAmendment #SustainableAgr...

Natural and artificial evolution of acetolactate synthase for crop breeding

-
        The natural and artificial evolution of acetolactate synthase (ALS), a key enzyme in the biosynthesis of branched-chain amino acids, plays a significant role in advancing crop breeding strategies. Naturally occurring mutations in ALS genes have provided insights into herbicide resistance mechanisms, while artificial evolution through gene editing and mutagenesis has enabled the development of crop varieties with improved resistance to ALS-inhibiting herbicides. This dual approach not only enhances crop resilience but also contributes to sustainable agricultural practices by reducing chemical inputs and enabling precision breeding techniques. As a pivotal target for both research and practical application, ALS evolution represents a critical interface between molecular biology and modern crop improvement.

Image analysis method combined with machine learning for the prediction of soil and air quality

-
      The integration of image analysis methods with machine learning has opened new frontiers in predicting soil and air quality with greater accuracy and efficiency. High-resolution satellite imagery, drone-captured visuals, and hyperspectral imaging are now widely used to extract visual features such as color variations, texture patterns, vegetation health, and land-use changes. These visual indicators are then fed into machine learning models—such as convolutional neural networks (CNNs) and support vector machines (SVMs)—to identify correlations with soil parameters (like moisture, pH, organic content) and air pollutants (like particulate matter, NOx, and CO₂). This data-driven approach enables continuous environmental monitoring, early warning systems, and sustainable land management strategies. The fusion of visual data with predictive analytics not only enhances spatial coverage but also minimizes the need for invasive sampling, offering a scalable solution for sm...
