In Situ and High Resolution TEM Studies of Nano-scale Materials

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

NANO- SCALE LOCALIZED CORROSION STUDIES OFEN AW- 3003ALALLOYBYSEM-EDS, SKPFM AND IN-SITU AFM

Abstract: Localized corrosion of aluminum alloys is often triggered by intermetallic particles, IMP’s. To understandthe role of IMP’s in corrosion initiation of EN AW-3003, efforts were made to combine nano-scale ex-situ analysis ofthe IMP’s by SEM-EDS, SKPFM and in-situ AFM monitoring of the localized attack in chloride containing solution.The results showed that two distinct types of eutectic...

In-Situ Mechanical Testing of Nano-Component in TEM

Combining High-Resolution TEM on Graphene With In-Situ Hall Measurements 105 Combining High-Resolution TEM on Graphene With In-Situ Hall Measurements

We describe an approach allowing high-resolution transmission electron microscopy (HRTEM) on specimens like graphene and the investigation on their electronic transport properties at the same time. The experimental set-up presented here is based on the modification of a commercial TEM specimen holder and on a specially designed sample carrier. A customized Hall sensor confirms that the local ma...
