On the origin of the anomalous compliance of dealloying-derived nanoporous gold
B. -N. D. Ngô, B. Roschning, K. Albe +2
The origin of the anomalously compliant behavior of nanoporous gold is studied by comparing the elasticity obtained from molecular dynamics (MD) and finite element method (FEM) sim…
Structural origins of the boson peak in metals: From high-entropy alloys to metallic glasses
Tobias Brink, Leonie Koch, Karsten Albe
The boson peak appears in all amorphous solids and is an excess of vibrational states at low frequencies compared to the phonon spectrum of the corresponding crystal. Until recentl…
Determination of optimal reversed field with maximal electrocaloric cooling by a direct entropy analysis
Yang-Bin Ma, Nikola Novak, Karsten Albe +1
Application of a negative field on a positively poled ferroelectric sample can enhance the electrocaloric cooling and appears as a promising method to optimize the electrocaloric c…
State transition and electrocaloric effect of BaZrTiO: simulation and experiment
Yang-Bin Ma, Christian Molin, Vladimir V. Shvartsman +4
The electrocaloric effect (ECE) of BaZrTiO (BZT) is closely related to the relaxor state transition of the materials. This work presents a systematic study on the…
Enhancement of the electrocaloric cooling by electric field reversal: simulation and experiment
Yang-Bin Ma, Nikola Novak, Jurij Koruza +3
An improved thermodynamic cycle is proposed, where the cooling effect of an electrocaloric refrigerant is enhanced by applying a reversed electric field. In contrast to conventiona…
