Abstract Lithium (Li) metal anodes (LMAs) have garnered significant attention as a potential
solution for developing high-energy density batteries, given their theoretical specific capacity …

Miniaturization of mechanical structures offers excellent performances of the device while
has brought problems of fracture at nanoscale. However, whether the classical fracture …

The growing research interest in dislocation‐tuned functionality in ceramics is evident, with
the most recent proofs‐of‐concept for enhanced ferroelectric properties, electrical …

Brittle fracture and ductile failure are critical events for any structural or functional
component, as it marks the end of lifetime and potential hazard to human life. As such …

The local stress state and microstructure near the crack-tip singularity control the fracture
process. In ductile materials multiple toughening mechanisms are at play that dynamically …

Diamond possesses excellent thermal conductivity and tunable bandgap. Currently, the high‐
pressure, high‐temperature, and chemical vapor deposition methods are the most promising …

Ductility, namely a material's capacity for plastic deformation, is a key property for preventing
fracture-driven failure in engineering parts. While some brittle materials are known to exhibit …

In this work, in-situ TEM compression has been carried out to observe the nucleation and
movement of< c+ a> dislocations in Mg–Y alloys. The effect of Y contents (0.4 wt% and 4 …

Mechanical size effects are a well known phenomenon when the sample volume is reduced
or the characteristic length of the microstructure is changed. While size effects in micropillar …
