Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Cooperative Atomic Mechanism of Emergent Tilted Magnetic Anisotropy

Advanced Electronic Materials
Understanding the atomic origin of magnetic anisotropy is of paramount importance for designing advanced magnetic materials for the next generation of magnetic and spintronic technologies. The Ru‐substituted La0.70Sr0.30MnO3 (Ru‐LSMO) system has recently

Magnetic Anisotropy in Divalent Lanthanide Complexes

, 2019
We report here high-level ab initio calculations for [LnO], Ln=Tb, Dy, Ho, which show that divalent lanthanides can exhibit equally strong magnetic anisotropy and magnetization blocking ...

Ferroelectric Control of Magnetic Anisotropy

Nano Letters, 2011
We demonstrate unambiguous evidence of the electric field control of magnetic anisotropy in a wedge-shaped Co film of varying thickness. A copolymer ferroelectric of 70% vinylidene fluoride with 30% trifluoroethylene, P(VDF-TrFE) overlays the Co wedge, providing a large switchable electric field. As the ferroelectric polarization is switched from up to

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

Advanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...
