Heat capacities and thermal expansion coefficients of iron triad metals

Конденсированные среды и межфазные границы, 2023
One of the complex problems relating to the thermodynamics of a substance is creating an adequate description of its thermal properties. For example, the Einstein and Debye models (as well as in various modifications of these models) the heat capacity is

Direct Observation of the Deformation Mechanism of Twin-Structured Ni NWs under Bending Strain

Metals, 2022
In situ atomic-scale bending tests of twin-structured Ni nanowires were realised using a homemade deformation device. The results showed that the plastic deformation mechanism in twin-structured Ni nanowires depended on the deformation stage.

Electronic properties of dislocations [PDF]

Applied Physics A, 2015
Dislocations are one-dimensional crystal defects. Their dimension characterize the defects as nanostructures (nanowires). Measurements on defined dislocation arrays proved numerous exceptional electronic properties. A model of dislocations as quantum wires is proposed.
