High‐Performance Polymer‐derived Ceramics in LCD 3D Printing
Advanced Science, EarlyView.This study highlights the potential of silicon oxycarbide‐based formulations for producing polymer‐derived ceramics with superior properties via LCD 3D printing. VMM‐based ceramics demonstrate a remarkable 50‐fold increase in compressive strength (up to 17 MPa) compared to SPR‐684, along with exceptional high‐temperature survivability (up to 1500 °C ...

Advanced Science, EarlyView.The anisotropic‐structure SiC@SiO2 ceramic fiber aerogels feature aligned layers stacking layer‐by‐layer with the same direction and highly oriented 1D fibers inside each layer, resulting in an anisotropy factor as high as 5.08. Not only does it have 60% high recoverable deformation, but it also shows great promise for thermal protection in extreme ...

Leaky Wave Antenna-Equipped RF Chipless Tags for Orientation Estimation [PDF]
arXivAccurate orientation estimation of an object in a scene is critical in robotics, aerospace, augmented reality, and medicine, as it supports scene understanding. This paper introduces a novel orientation estimation approach leveraging radio frequency (RF) sensing technology and leaky-wave antennas (LWAs). Specifically, we propose a framework for a radar

Self‐Oscillation in Active Wires with Asymmetric Willis‐Type Viscosity
Advanced Science, EarlyView.This study suggests a self‐oscillation strategy enabled by a new set of material parameters, namely the asymmetric Willis‐type viscosity, to bias and independently control oscillation mode shapes as well as frequencies. The exemplified active wire can benefit the development of autonomous materials to construct soft motors, agitators, pumps, and ...

Lattice‐Distortion‐Driven Reduced Lattice Thermal Conductivity in High‐Entropy Ceramics
Advanced Science, EarlyView.Long‐believed potential mechanisms of lattice distortion and mass fluctuation for the reduced lattice thermal conductivity are explored by designing two groups of high‐entropy diborides based on machine‐learning‐potential‐based molecular dynamics simulations.
