Comparison of Electromagnetic Induction and Electrical Resistivity Tomography in Assessing Soil Salinity: Insights from Four Plots with Distinct Soil Salinity Levels

Land
Electromagnetic induction (EMI) and electrical resistivity tomography (ERT) are geophysical techniques measuring soil electrical conductivity and providing insights into properties correlated with it to depths of several meters. EMI measures the apparent

Recent Developments in Electrochemical Lignin Depolymerization Using Flow Systems: A Mini Review

ChemElectroChem, Volume 13, Issue 16, 18 August 2026.
This review summarizes the current state of the electrochemical depolymerization of lignin focusing on studies performed in flow cells. Three anodic strategies are distinguished: oxygen evolution reaction substitution for energy‐efficient hydrogen generation, nonselective oligomer production, and selective aromatic monomer synthesis, such as vanillin ...

Gamma Rays Signal the Vulnerability of Forest to Extreme Drought

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Extreme drought and heat are driving forest die‐off globally, yet regional‐scale mapping of subsurface water storage capacity, governing forest vulnerability, remains a major challenge. Here, we demonstrate that airborne gamma‐ray spectrometry (GRS) of potassium (40K) decay provides a powerful proxy for subsurface constraints on water ...
