To comprehend the mechanical behavior of a polycrystalline material, an in-depth analysis
of individual grain boundary (GB) and dislocation interactions is of prime importance. In the …

Etch pits could form on an exposed surface of a crystal when the crystal is exposed to an
etching environment or chemicals. Due to different dissolution rates along various crystalline …

The origin of the indentation size effect has been extensively researched over the last three
decades, following the establishment of nanoindentation as a broadly used small-scale …

Most oxide ceramics are known to be brittle macroscopically at room temperature with little
or no dislocation‐based plasticity prior to crack propagation. Here, we demonstrate the size …

We present a new method based on uncorrelated misorientation measurements by Electron
Backscattered Diffraction (EBSD) to characterize the dislocation density of site-specific areas …

Polysilazane coatings have a broad need in real‐life applications, which require low
processing or working temperature. In this work, five commercially available polysilazanes …

Nanoindentation is a convenient method to investigate the mechanical properties of
materials on small scales by utilizing low loads and small indentation depths. However, the …

Dislocations have been identified to modify both the functional and mechanical properties of
some ceramic materials. Succinct control of dislocation‐based plasticity in ceramics will also …

We report room‐temperature bulk plasticity mediated by dislocations in single‐crystal cubic
potassium tantalate oxide (KTaO3), contrasting the conventional knowledge that single …

Dislocation‐tuned functionality in ceramic oxides for potential versatile applications gains
increasing attention. As the widespread chemical do** suffers from poor temperature …
