Highly Oriented SiC@SiO2 Ceramic Fiber Aerogels with Good Anisotropy of the Thermal Conductivity and High‐Temperature Resistance

open access: yesAdvanced 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 ...

Modelling interactions between waves and diffused interfaces

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 95, Issue 2, Page 215-241, February 2023., 2023
When simulating multiphase compressible flows using the diffuse‐interface methods, important issues arise during the interaction of waves with diffused interfaces. A solution is to use a pressure‐disequilibrium model with finite, instead of infinite, pressure‐relaxation rate.

Excellent Dynamic Non‐Wetting Performance Induced by Asymmetric Structure at Low Temperatures: Retraction Actuation and Nucleation Inhibition

open access: yesAdvanced Science, EarlyView.
Special asymmetric structures with interfacial thermal resistance characteristics can not only provide time for droplet ejection by inhibiting the nucleation process inside the microstructure but also synchronously reduce droplet adhesion and increase the driving force during the droplet retraction stage by enhancing the horizontal Laplace force ...

Lattice‐Distortion‐Driven Reduced Lattice Thermal Conductivity in High‐Entropy Ceramics

open access: yesAdvanced 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.

A Universal Toughening and Energy‐Dissipating Strategy for Impact‐Resistant 3D‐Printed Composites

open access: yesAdvanced Science, EarlyView.
A universal toughening and energy dissipation strategy inspired by B─O bonds, which can significantly enhance the mechanical properties of composites, enables 3D‐printed smart impact‐resistant structures. Abstract 3D‐printed polymer‐based composites are promising for various engineering applications due to high strength‐to‐weight ratios and design ...
