Autor: Kirill Sidnov, Denis Konov, Ekaterina A. Smirnova, Alena V. Ponomareva, Maxim P. Belov
Publikováno v: Metals, Vol 14, Iss 4, p 438 (2024)
In this paper, the applicability of machine learning for predicting the elastic properties of binary and ternary bcc Ti and Zr disordered alloys with 34 different doping elements is explored. The original dataset contained 3 independent elastic const

Publikováno v: ACS nano. 15(8)
Most of the studied two-dimensional (2D) materials are based on highly symmetric hexagonal structural motifs. In contrast, lower-symmetry structures may have exciting anisotropic properties leading to various applications in nanoelectronics. In this

Publikováno v: Inorganic chemistry. 58(14)
Sulfur and nitrogen represent one of the most studied inorganic binary systems at ambient pressure on account of their large wealth of metastable exotic ring-like compounds. Under high pressure conditions, however, their behavior is unknown. Here, su
