Self‐Templated Hierarchically Porous Graphitic Aerogels for Emi Shielding

Small, EarlyView.
This work presents a self‐templated, single‐component hierarchically porous graphitic aerogel derived from albumen through pyrolysis for lightweight EMI shielding applications. Controlled thermal processing enables tunable structure, electrical conductivity, and attenuation mechanisms.

Synaptic ultrastructural alterations in human focal cortical dysplasia: Insights from volume electron microscopy

Epilepsia, EarlyView.
Abstract Objective Focal cortical dysplasia (FCD) is a developmental malformation of the cerebral cortex and a leading cause of drug‐resistant epilepsy in children and young adults. Disruption of the excitation–inhibition (E–I) balance is a hallmark of neuronal hyperexcitability in FCD, yet the underlying synaptic ultrastructural changes remain poorly ...

Electron microscopy‐based three‐dimensional subcellular imaging of plant male gametophyte

Journal of Integrative Plant Biology, EarlyView.
The Aquilos2 Cryo‐FIB workflows provide practical routes for cryo‐electron tomography and volume imaging in plant structural biology. ABSTRACT Understanding cellular events in three dimensions (3D) is of great importance for the annotation and illustration of biological processes in a contextual way. Imaging techniques based on electron microscopy (EM),

Evaluating the possible role of bottom currents and internal waves in shaping seafloor morphology in a mesophotic reef

Sedimentology, EarlyView.
ABSTRACT Mesophotic reefs are located in low light conditions which, depending on the region, are usually found in water depths greater than ~30 m. They are less affected by ocean warming than reefs found in shallower water depths and thus might become increasingly important for the sustainability of marine biodiversity.
