Direct Visualization of Temperature-Induced Phase Separation of Completely Miscible Au-Pd Alloy by In-Situ TEM
Abhijit Roy, Simon Hettler, Raul Arenal
In-situ transmission electron microscopy (TEM) studies reveal key insights into the structural and chemical evolution of nanoparticles (NPs) under external stimuli like heating and…
Toward thermoelectric characterization of (nano)materials by in situ transmission electron microscopy
Simon Hettler, Mohammad Furqan, Andres Sotelo +1
We explore the possibility to perform an in-situ transmission electron microscopy (TEM) thermoelectric characterization of materials. A differential heating element on a custom in-…
Room-Temperature Anomalous Hall Effect in Graphene in Interfacial Magnetic Proximity with EuO Grown by Topotactic Reduction
Satakshi Pandey, Simon Hettler, Raul Arenal +6
We show that thin layers of EuO, a ferromagnetic insulator, can be achieved by topotactic reduction under titanium of a Eu2O3 film deposited on top of a graphene template. The redu…
Stable CoO Nanoscrolls With Outstanding Electrical Properties
Simon Hettler, Kankona Singha Roy, Raul Arenal +1
Layered CoO is of great interest for its promising properties but is meta-stable in its bulk form. CoO was synthesized by converting the quasi-one-dimensional crystal struc…
Catalysts for the hydrogen evolution reaction in alkaline medium: Configuring a cooperative mechanism at the Ag-AgS-MoS interface
Avraham Bar-Hen, Simon Hettler, Ashwin Ramasubramaniam +3
Designing electrocatalysts for HER in alkaline conditions to overcome the sluggish kinetics associated with the additional water dissociation step is a recognized challenge in prom…
A Detailed Investigation of the Onion Structure of Exchanged Coupled Magnetic Fe(3-delta)O4@CoFe2O4@Fe(3-delta)O4 Nanoparticles
Kevin Sartori, Anamaria Musat, Fadi Choueikani +7
Nanoparticles (NPs) which combine several magnetic phases offer wide perspectives for cutting edge applications because of the high modularity of their magnetic properties. Besides…
Thin-film based phase plates for transmission electron microscopy fabricated from metallic glasses
M. Dries, S. Hettler, T. Schulze +6
Thin-film based phase plates are meanwhile a widespread tool to enhance the contrast of weak-phase objects in transmission electron microscopy (TEM). The thin film usually consists…
