Towards In-Situ Electron Microscopy Studies of Flash Sintering

In situ transmission electron microscopy and scanning transmission electron microscopy studies of sintering of Ag and Pt nanoparticles

Transmission electron microscopy and scanning transmission electron microscopy studies were conducted in situ on 2–5 nm Pt and 10–40 nm Ag nanoparticles to study mechanisms for sintering and to measure relevant sintering kinetics in nanoscale particles. Sintering between two separated particles was observed to initiate by either (1) diffusion of the particles on the sample support or (2) diffus...

Flash Scanning Electron Microscopy

Scanning Electron Microscopy (SEM) is an invaluable tool for biologists and neuroscientists to study brain structure at the intracellular level. While able to image tissue samples with up to 5 nm isotropic resolution, image acquisition is prohibitively slow and limits the size of processed samples. In this work, we propose a novel approach to speeding up imaging when looking for specific struct...

An Electron Microscopy Study of Sintering in Three Dental Porcelains

In the manufacture of yttria partially stabilised zirconia dental prostheses, layers of porcelain veneer are sintered onto zirconia copings in order to reduce surface hardness and to produce an aesthetically pleasing finish. The stress of this interfacial bond and of the near-interface porcelain layers is crucial for reducing the likelihood of chipping during use. An improved understanding of t...

In Situ Heating Transmission Electron Microscopy

93 Abstract Temperature is one of the most important factors affecting the state and behavior of materials. In situ heating transmission electron microscopy (TEM) is a powerful tool for understanding such temperature effects, and recently in situ heating TEM has made significant progress in terms of temperature available and resolution attained. This article briefly describes newly developed sp...
