In-situ TEM Observation with Environmental Cell for Hydrogen Storage Materials

In situ observation of facet-dependent oxidation of graphene on platinum in an environmental TEM.

We performed a direct observation of a crystal facet-dependent oxidation of graphene layers on platinum nanocrystals at atomic resolution in an environmental transmission electron microscope. Combined with density functional theory calculations, our work provides a novel approach for the dynamical exploration of the facet-dependent reactions at the atomic level.

Development of TEM Holder Generating In-Plane Magnetic Field Used for In-Situ TEM Observation

For easy performance of Lorentz microscopy with simultaneous electric measurements, a special specimen holder for transmission electron microscopy (TEM) has been developed that has electromagnets to generate magnetic field and four leads for electric measurements. This TEM holder was evaluated by checking experimental results of permalloy (Ni0.8Fe0.2) patterns. Clear observations of domain wall...

In situ Analytical TEM of Ilmenite Reduction in Hydrogen

Ilmenite (FeTiO3) is an important mineral, formed in igneous and metamorphic rocks, and is the main feedstock for the titanium industry. Ilmenite is also an attractive and inexpensive oxygen carrier for chemical-looping combustion (CLC), one of the most promising technologies to accomplish CO2 capture in power plants [1]. The technique uses solid metal oxides as an oxygen carrier, which transfe...
