A Compact Annular Electrostatic Clutch Joint: Dynamic Response Modeling and Time‐Sharing Control for Underactuated Robots

SmartBot, EarlyView.
Electrostatic clutches offer programmable variable stiffness for multi‐DOF robots, but their continuous motion is usually bottlenecked by spatial constraints and detachment delays. Here, the authors report a compact annular electrostatic clutch joint with a biphasic amplitude‐frequency modulation strategy to rapidly mitigate residual polarization ...

Universal Confinement Length Governs Radical Depolymerization Kinetics in Nanoconfined Polymers

Small, EarlyView.
Analysis of PMMA depolymerization kinetics identifies a critical threshold under extreme nanoconfinement where segmental mobility saturation prevents further increases in depolymerization temperature. ABSTRACT Thermal depolymerization is typically studied in bulk, yet many systems involve polymers confined within nanoscale geometries. Understanding how

HS‐AFM Reveals Hierarchical RNA Folding Driving Condensate Assembly and Material States

Small, EarlyView.
High‐speed atomic force microscopy reveals the nanoscale pathway of RNA condensate formation, from individual RNA folding to higher‐order assembly. Quantitative analyses of fusion dynamics and nanomechanical properties distinguish liquid‐like poly A condensates from solid‐like total RNA assemblies, providing a direct link between RNA self‐assembly and ...

Perforation Enhances Sound Insulation in Plate Lattice Metamaterials

Small, EarlyView.
Herein, perforations are engineered into face‐centered cubic plate lattice metamaterials to convert normally detrimental openings into acoustically active features. Experiments, finite‐element analyses, and a reduced‐order transfer‐matrix model show that selected perforation geometries activate Helmholtz‐like and cavity‐mediated resonances, enhancing ...

Fitting an Origin-Displaced Logarithmic Spiral to Empirical Data by Differential Evolution Method of Global Optimization

Logarithmic spirals are abundantly observed in nature. Gastropods (such as nautilus, cowie, grove snail, thatcher, etc.) in the mollusca phylum have spiral shells, mostly exhibiting logarithmic spirals vividly. Spider webs show a similar pattern. The low-

Van der Waals Integration of Tellurium Nanowires With Graphene Oxide for Performance‐Enhanced Ion‐Sensitive Field‐Effect Transistors

Small, EarlyView.
Van der Waals integration of 1D tellurium nanowires with 2D graphene oxide enables high‐performance ISFET arrays with exceptional stability and apparent super‐Nernstian pH sensitivity, paving the way for next‐generation bioelectronic diagnostics and environmental monitoring.
