Energetic Validation of Various Crystal Structures in Zr2CoZ (Z = Al, Ga, In) Heusler Alloys
We energetically validate new Zr2CoZ (Z = Al, Ga, In) systems in the most common cubic crystal structures of Heusler alloys, that is, regular and inverse full-Heusler structures. The regular Heusle...
Structural, Mechanical and Electronic Properties of o-BC6N
Abstract The mechanical and electronic properties of o-BC6N are studied by using first-principles calculations. The anisotropy studies of Young’s modulus, shear modulus and Poisson’s ratio show that…

TLDR
It is still unknown whether there are families of tight knots whose lengths grow faster than linearly with crossing numbers, but the largest power has been reduced to 3/z, and some other physical models of knots as flattened ropes or strips which exhibit similar length versus complexity power laws are surveyed.
