From 2D to 3D Characterization of Materials Subjected to Extreme Pressure and Temperature Conditions

Farhang Nabiei

Planetesimal were the first planetary objects to form in the solar system, which later grew to make the proto-planets. Most of these bodies were differentiated as a result of internal heating. Several differentiated bodies have, then, been accreted followi ...

A Gibeon meteorite yields a high-performance water oxidation electrocatalyst

Paul Joseph Dyson, Arnaud Magrez, Kevin Sivula, Nestor Guijarro Carratala, Florian Le Formal, Mathieu Steven Prévot, Aswin Gopakumar, Wiktor Stefan Bourée

Examining the electrocatalytic performance of naturally-occurring metallic minerals is of interest for energy conversion applications given their unique atomic composition and formation history. Herein, we report the electrocatalytic function of an iron-ba ...

Atomistic simulation of the a(0) < 1 0 0 > binary junction formation and its unzipping in body-centered cubic iron

Seyed Masood Hafez Haghighat

Molecular dynamics simulation is used to study the formation of the a(0) < 1 0 0 > binary dislocation junction in body-centered cubic Fe. Results show that under an applied strain two intersecting 1/2 a(0) < 1 1 1 > dislocations, one mobile edge and one im ...

Energy-selective neutron imaging for morphological and phase analysis of iron-nickel meteorites

Steven Luc X Peetermans

We propose energy-selective neutron imaging as a new and non-destructive method to investigate rare metallic meteorites. It is based on attenuation of a neutron beam of limited spectral distribution in a sample depending on the elemental composition and cr ...
