Single‐atom materials (SAMs) have been widely investigated during the past years,
providing many high‐performance materials applied in catalyst, battery, solar cell, and so …

We review some of the factors that influence the hardness of polycrystalline materials with
grain sizes less than 1 µm. The fundamental physical mechanisms that govern the hardness …

Nanostructured metallic materials having nanocrystalline and ultrafine-grained structures
show exceptional mechanical properties, eg superior strength, that are very attractive for …

Grain rotation is a well-known phenomenon during high (homologous) temperature
deformation and recrystallization of polycrystalline materials. In recent years, grain rotation …

The mechanical properties of nanocrystalline materials are reviewed, with emphasis on their
constitutive response and on the fundamental physical mechanisms. In a brief introduction …

Grain boundary mediated plasticity (eg, grain rotation and grain boundary sliding) plays a
critical role in determining the deformation behavior of polycrystals, which is especially …

Nanocrystalline metals and alloys, with average and range of grain sizes typically smaller
than 100 nm, have been the subject of considerable research in recent years. Such interest …

Complex (dusty) plasmas are composed of a weakly ionized gas and charged microparticles
and represent the plasma state of soft matter. Complex plasmas have several remarkable …
