New manufacturing strategy improves graphene airgel sensitivity and durability for human-machine interfaces
Graphene airgel shows potential as a high-performance pressure sensor in human-machine interfaces due to its mechanical properties and electrical conductivity. Anisotropic chitosan graphene oxide (CS-GO) airgel metamaterials with highly ordered honeycomb microstructures were synthesized using conventional directional freeze casting. Subsequently, cross-linked chitosan and reduced graphene oxide (CCS-rGO) aerogels with buckled networks achieved by heating and post-crosslinking at 180 °C for…

Capturing finer-scale topographic differences improves the ability of Earth system models to reproduce observations
Spatial pattern of number of topographic units (TGU) per 0.5 degree grid. We demonstrate the ability of a terrain-based subgrid structure to capture terrain heterogeneity across a mountainous region and associated data that is a measure of the computational efficiency of the data reduction metric (DRM). We define a variable number of TGUs per grid in conjunction with the allocation…
