Large‐Scale Structural Dynamics in the Tail Fiber Modulate the Infective Transition of the T7 Bacteriophage

open access: yesSmall, EarlyView.
During host recognition, the fibers of T7 bacteriophages transition from a capsid bound state to an extended conformation, which requires some level of fiber flexibility. By using high‐speed atomic force microscopy, we show that the fibers have an internal molecular hinge and a torsionally compliant coiled‐coil region.

Spatial Activity Patterning and Topological Defect Transport in Acoustically Energized Active Liquid Crystals

open access: yesSmall, EarlyView.
Channel geometry is used to pattern activity in acoustically energized active liquid crystals, producing controlled, directional transport of topological defects. The mechanism is revealed by experiment and minimal modeling, offering a new design principle for programmable topological transport and active microfluidic architectures. ABSTRACT Patterning

Geometry‐Encoded Programmable Mechanics in Single‐Material Dual‐Phase Metamaterials

open access: yesSmall, EarlyView.
Inspired by the unique soft‐hard heterogeneous architecture of nacre, this study proposes a novel class of dual‐phase (DP) metamaterials. The DP metamaterials exhibit programmable nonlinear mechanical responses, tailored failure processes, and enhanced energy absorption by systematically varying the spatial coding patterns of soft‐hard unit cells ...

Martian‑Regolith Simulant Confined Nanogenerators for Wireless Tactile Sensing for Human‐Machine Interface

open access: yesSmall, EarlyView.
A Martian regolith‐simulant/PDMS triboelectric nanogenerator is developed as an ISRU‐inspired, self‐powered tactile sensor for wireless human–machine interface applications. ABSTRACT Achieving a sustainable energy system for space missions remains challenging due to the continued reliance on Earth‐supplied materials.
