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…
Aberration-corrected transmission electron microscopy with Zernike phase plates
Simon Hettler, Raul Arenal
We explore the possibility of applying physical phase plates (PPs) in combination with aberration-corrected transmission electron microscopy. Phase-contrast transfer characteristic…
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…
Shelling with MoS Functional CuS@MoS2 Hybrids as Electrocatalysts for the Oxygen Reduction and Hydrogen Evolution Reactions
Avraham Bar-Hen, Ronen Bar Ziv, Tsion Ohaion-Raz +4
The development of noble-metal free electrocatalysts is of high importance for clean energy conversion applications. MoS has been considered as a promising low cost catalyst fo…
Comparative image simulations for phase-plate transmission electron microscopy
Simon Hettler, Raul Arenal
Numerous physical phase plates (PP) for phase-contrast enhancement in transmission electron microscopy (TEM) have been proposed and studied with the hole-free or Volta PP having a…
In-situ reduction by Joule heating and measurement of electrical conductivity of graphene oxide in a transmission electron microscope
Simon Hettler, David Sebastian, Mario Pelaez-Fernandez +3
Graphene oxide (GO) is reduced by Joule heating using in-situ transmission electron microscopy (TEM). The approach allows the simultaneous study of GO conductivity by electrical me…
