Materials engineers have found that the juncture at which graphene sheets meet does not compromise the material's strength. These so-called grain boundaries are so strong, in fact, that the sheets are ...

Alloy design model offers faster, more accurate predictions by factoring in material defects
The new model takes into account an important class of material defects (grain boundaries) and the tendency of the mixed solutes to gather—or segregate—around the structural imperfections during alloy ...
(Nanowerk News) Thin-film zeolite membranes with tiny, molecule-sized pores are one step closer to replacing the energy-intensive processes now used in industrial separations, a group of academic ...
Recently, the research group led by Prof. LIU Changsong from Institute of Solid State Physics (ISSP), Hefei Institutes of Physical Science (HFIPS) of Chinese Academy of Sciences (CAS) developed a set ...
Results indicate that grain boundary strength and motion, accommodated by either shear-coupled migration (SCM) or grain boundary sliding (GBS), strongly varies with pressure resulting in grain ...

Engineers have studied the structure and properties of the commonly occurring planar defects at the atomic scale, which spans only a few tenths of a nanometer. In the quest to design more efficient ...
Grain boundaries are interfaces that separate different crystallographic regions, known as grains, within a polycrystalline material. In nanomaterials, grain boundaries play a crucial role in ...
