Complex Electrical Conductivity of a Single‐Fractured Rock: Fracture‐and‐Matrix Coupling Mechanism and Aperture Size Predictions

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Fractured rocks play a crucial role in myriad natural and engineered systems, including Earth's critical zone, oil/gas/geothermal reservoirs, and geological CO2/H2/waste storage systems. While complex electrical conductivity is extensively used to estimate the pore and grain sizes of conventional porous rocks and soils, it is rarely used to ...

Land Models Likely Underestimate the Impact of Future Atmospheric Dryness on European Tree Growth

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Understanding how the land carbon sink will be altered by climate change is critical for projecting future atmospheric CO2 concentrations under different emission pathways in Earth System Models (ESMs). Most land models assume that woody growth, the main driver of land carbon storage, is driven by photosynthetic carbon supply.

Earthward Propagated Auroral Kilometric Radiation: Observations From Polar

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Auroral Kilometric Radiation (AKR), the strongest natural radio emission from Earth's magnetosphere, has been primarily observed in space. It is generally understood to propagate anti‐Earthward and be detected at large radial distances, while Earthward‐directed waves are thought to be blocked by the ionosphere. Surprisingly, AKR‐like emissions

Time‐Resolved SNOM via Phase‐Domain Sampling

open access: yesNanophotonics, Volume 15, Issue 12, 25 June 2026.
Time‐resolved scanning near‐field optical microscopy (tr‐SNOM) grants access to the dynamic dielectric function of monolayer and multilayer WS2, using visible wavelengths. In order to use a femtosecond laser with a repetition rate of 200 kHz, the signal is sampled and demodulated in the modulation phase domain, marking the first realization of tr‐SNOM ...

Free Vibration of Hemp Fiber‐Reinforced Laminated Composite Curved Beams Using Generalized Differential Quadrature Method

open access: yesPolymer Composites, Volume 47, Issue 12, Page 11300-11318, 20 June 2026.
Schematic representation of hemp‐, glass‐, and carbon‐based laminated composite curved beams, including different stacking sequences and their vibration response. ABSTRACT In recent years, increasing environmental awareness has stimulated growing interest in natural fiber‐reinforced composites (NFRCs) due to their eco‐friendly composition ...
