Smart Transfemoral Prosthetic Socket with Motorized Cable‐Driven System

open access: yesAdvanced Intelligent Systems, EarlyView.
This study presents an innovative transfemoral socket featuring a motorized cable‐driven system and a sensorized liner, designed to adapt to changes in residual limb volume while monitoring interface pressures. Users can seamlessly control the socket in both open‐ and closed‐loop modes via a customized mobile application, enhancing comfort and ...

Decreasing the Cost of Morphing in Adaptive Morphogenetic Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
Shape‐morphing propulsive limbs enhance locomotion across land‐to‐water transitions, but prior designs rely on thermally responsive components, coupling performance to environmental temperature. This study introduces a pressure‐responsive mechanism that reduces morphing energy costs, enables rapid transitions, and minimizes failure modes.

Fast Sodium Ion Conductivity in Pristine Na8SnP4: Synthesis, Structure and Properties of the Two Polymorphs LT‐Na8SnP4 and HT‐Na8SnP4

open access: yesAngewandte Chemie, EarlyView.
Sodium‐ion conductors show great promise for use in rechargeable solid‐state batteries due to the high natural abundance of sodium. As a pristine material, Na8SnP4 demonstrates relatively high ionic conductivity and offers significant room for further enhancement, owing to its structure built on well‐known tetrahedral building blocks. Additionally, its

Phylogenomics, historical biogeography, and diversification of leaf traits in the Malagasy‐endemic genus Uncarina (Pedaliaceae)

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Uncarina contains 14 species of woody plants endemic to Madagascar. Its occurrence across dryland biomes on the island make it an interesting system to study the diversification of the flora. Methods Using samples of all species and 512 nuclear loci, we reconstructed phylogenetic trees to examine species relationships and assess their ...

Pressure‐Driven Reactivity in Dense Methane‐Nitrogen Mixtures

open access: yesAngewandte Chemie, EarlyView.
CH4 and N2 are abundant molecules in our solar system and are the primary constituents of Titan's atmosphere. Under extreme pressures and temperatures within a diamond anvil cell, CH4 and N2 are demonstrated to react to form a range of compounds, dependent on the conditions and initial concentrations.
