Corrosion of Metal Films Observed Using In Situ and Ex Situ Electron Microscopy

Corrosion of Metal Films Observed Using In Situ and Ex Situ Electron Microscopy

Localized corrosion refers to the accelerated dissolution of metals and alloys due to the breakdown of their protective passive films at select sites [1]. Developing an understanding of localized corrosion phenomena has significant practical importance due to the deleterious effects of pit formation on the integrity of structural materials. However, localized corrosion is a challenging problem ...

Effects of Displacing Radiation on Graphite Observed Using in Situ Transmission Electron Microscopy Original Citation Effects of Displacing Radiation on Graphite Observed Using in Situ Transmission Electron Microscopy

Graphite is used as a moderator and structural component in the United Kingdom’s fleet of Advanced Gas-Cooled Reactors (AGRs) and features in two Generation IV reactor concepts: the Very High Temperature Reactor (VHTR) and the Molten Salt Reactor (MSR). Under the temperature and neutron irradiation conditions of an AGR, nuclear-grade graphite demonstrates significant changes to it mechanical, t...

Fabrication of Ti3SiC‌‌2-SiC max phase composites via in-situ and ex-situ synthesis

Recently, a series of three-component compounds with the combination of Mn+1AXn known as Max phases have been considered as a new material. One of the most important features of Max phases, is the self-healing property of them. The main reason for considering Max Phases is a unique collection of unusual properties including their metallic, ceramic, physical, and mechanical properties. One of th...

Insights into hydrophobic molecule release from polyelectrolyte multilayer films using in situ and ex situ techniques.

We report on the loading and release of curcumin (a hydrophobic polyphenol with anti-inflammatory and anti-bacterial properties) from polyelectrolyte multilayers composed of poly(diallyldimethylammonium chloride) (PDADMAC) and poly(sodium 4-styrenesulfonate) (PSS). We have used the in situ techniques of attenuated total reflectance (ATR) FTIR spectroscopy and quartz crystal microbalance with di...
