Compared with fuel cells and electrochemical capacitors, dielectric capacitors are regarded
as promising devices to store electrical energy for pulsed power systems due to their fast …

Metallic materials are usually composed of single phase or multiple phases, which refers to
homogeneous regions with distinct types of the atom arrangement. The recent studies on …

Nanostructured metals are usually strong because the ultrahigh density of internal
boundaries restricts the mean free path of dislocations. Usually, they are also more brittle …

High‐performance ferroelectric materials are widely used in various electronic devices
owing to the function of mutual conversion among different energies, which mainly relates to …

Lead-free dielectric ceramics with both a high recoverable energy storage density (W rec)
and excellent mechanical performance are highly desirable for practical applications in next …

Metals can be processed to reach ultra-high strength, but usually at a drastic loss of ductility.
Here, we review recent advances in overcoming this tradeoff, by purposely deploying …

Conventional metals become harder with decreasing grain sizes, following the classical Hall-
Petch relationship. However, this relationship fails and softening occurs at some grain sizes …

It is not easy to fabricate materials that exhibit their theoretical 'ideal'strength. Most methods
of producing stronger materials are based on controlling defects to impede the motion of …

Magnesium (Mg) and its alloys usually show relatively low strength and poor ductility at
room temperature due to their anisotropic hexagonal close-packed (HCP) crystal structure …

Although diamond is the hardest material for cutting tools, poor thermal stability has limited
its applications, especially at high temperatures. Simultaneous improvement of the hardness …
