Hydrological Processes, Volume 40, Issue 6, June 2026.Temperature with depth measurements were used to model heat transport associated with sub‐daily changes in bidirectional hydrological fluxes. Tidal pumping along the shoreline, of alternating patterns of tidal intrusion during high tide and groundwater discharge during low tide, was modelled using a recursive estimation state‐space model.

InfoMat, Volume 8, Issue 6, June 2026.To address the low through‐plane thermal conductivity (λ⊥) of carbon fiber/epoxy composites, which poses thermal management challenges in the expanding low‐altitude economy, we incorporated spherical thermally reduced graphene (s‐TRG) as a bridging filler. This architectural design achieved a λ⊥ of 2.73 W m–1 K–1 at 10 wt% loading.

Ultrahigh Stiffness and Energy Absorption Properties of Isotropic Metallic Closed Cell Microlattices
Small, Volume 22, Issue 35, 23 June 2026.True closed cell microlattices without holes are fabricated for the first time using a novel Laser Sheet Fusion additive manufacturing technique. These microlattices exhibited isotropy in stiffness and surprisingly, strength and plasticity as well, despite orientation‐dependent failure mechanisms. Furthermore, material work hardening is shown to be key
