Abstract Ceramic aerogels are highly efficient, lightweight, and chemically stable thermal insulation materials but their application is hindered by their brittleness and low strength. Flexible nanostructure-assembled compressible aerogels have been

Grain boundary movement is closely related to plastic deformation of materials. In our contribution, C atoms are introduced into the grain boundary and a highly stable C chain network is formed through structural optimization. The results show that t

The thermally/mechanically-driven structural instability of nano- and coarse-grained polycrystalline metals originates from the unstable grain boundaries (GBs). GB segregation of solute elements could not only stabilize but also embrittle GBs. To imp
