A possible mechanism of ultrafast amorphization in phase-change memory alloys: an ion slingshot from the crystalline to amorphous position

open access: yes, 2008
We propose that the driving force of an ultrafast crystalline-to-amorphous transition in phase-change memory alloys are strained bonds existing in the (metastable) crystalline phase.

Efficient Process Development for Laser Powder Bed Fusion of a Soft‐Magnetic Metallic Glass Composite

open access: yesAdvanced Engineering Materials, EarlyView.
Iron‐based metallic glass alloys exhibit excellent soft‐magnetic properties, and unprecedented geometrical freedom in the design of soft‐magnetic metallic glass components is made possible by additive manufacturing. An efficient workflow for developing parameters for laser‐based powder bed fusion of a Fe‐based metallic glass alloy is presented along ...

Mapping rules from nodal line semimetal to topological crystalline insulator in face centered cubic lattice

open access: yes, 2020
We study what kind of topological crystalline insulator phase emerges from nodal line semimetal phases in the face-centered cubic system which is not indicated by topological indices when spin-orbit coupling (SOC) is introduced. We construct an effective

Effects of Carbon Nanoparticles on Triboelectro‐Induced Surface Defects

open access: yesAdvanced Engineering Materials, EarlyView.
Carbon nanoparticles added to grease modify the electrocontact behavior. The synergy of particle concentration and electric current dominates the surface damage of metals in contact. Electrical surface damage caused by current leakage is a critical challenge in high‐performance applications such as electric vehicle (EV) drivetrains and wind turbine ...

Crystalline structures and frustration in a two-component Rydberg gas

open access: yesNew Journal of Physics, 2015
We study the static behavior of a gas of atoms held in a one-dimensional lattice where two distinct electronically high-lying Rydberg states are simultaneously excited by laser light.

Properties of Electrodeposited Ni-B-ZrO2 Composite Coatings

open access: yesInternational Journal of Electrochemical Science, 2015
Ni-B coatings have high hardness and high wear resistance which make them suitable for automotive, aerospace, petrochemical, textile and electronics industries. Further improvement in properties (especially the corrosion behavior) will extend their range

Crystalline modification of a rare earth nucleating agent for isotactic polypropylene based on its self-assembly [PDF]

open access: yesRoyal Society Open Science, 2018
In this paper, the crystalline modification of a rare earth nucleating agent (WBG) for isotactic polypropylene (PP) based on its supramolecular self-assembly was investigated by differential scanning calorimetry, wide-angle X-ray diffraction and ...

Topological Crystalline Insulators

open access: yes, 2011
The recent discovery of topological insulators has revived interest in the topological properties of insulating band structures. In this work, we extend the topological classification of insulating band structures to include certain point group symmetry ...
