Title: In situ liquid SEM imaging analysis revealing particle dispersity in aqueous solutions

Abstract

A quantitative description on dispersity of boehmite (γ-AlOOH) particles, a key component for waste slurry at Hanford sites, can provide useful knowledge for understanding various physicochemical nature of the waste. In this work, in situ liquid scanning electron microscopy (SEM) was used to evaluate the dispersity of particles in aqueous conditions using a microfluidic sample holder, System for Analysis at Liquid Vacuum Interface (SALVI). Secondary electron (SE) images and image analyses were performed to determine particle centroid locations and the distance to the nearest neighbour particle centroid, providing reliable rescaled interparticle distances as a function of ionic strength in acidic and basic conditions. Our finding of the particle dispersity is consistent with physical insights from corresponding particle interactions under physicochemical conditions, demonstrating delicate changes in dispersity of boehmite particles based on novel in situ liquid SEM imaging and analysis.

Improving in situ liquid SEM imaging of particles

Journal Article Yu, Xiao‐Ying ; Arey, Bruce ; Chatterjee, Sayandev ; ... - Surface and Interface Analysis

This work presents in situ imaging of synthesized boehmite (γ-AlOOH) particles ranging from 20 to 100 nm, suspended in liquid, in a vacuum compatible microfluidic sample holder using a scanning electron microscopy (SEM) under the high vacuum mode and highlights the advantage of in situ liquid imaging of colloids. Nanometer-sized boehmite particles in high-level radioactive wastes at the Hanford site are known to be difficult to dissolve and cause rheological problems for processing in the nuclear waste treatment plant. Therefore, it is important to characterize boehmite particles and understand how they form aggregates in the liquid state. Several technical advancementsmore »« less

In situ imaging and elemental analysis of boehmite (AlOOH) particles in water is realized using the System for Analysis at the Liquid Vacuum Interface (SALVI) and Scanning Electron Microscopy (SEM). This paper describes the method and key steps in integrating the vacuum compatible SAVLI to SEM and obtaining secondary electron (SE) images of particles in liquid in high vacuum. Energy dispersive x-ray spectroscopy (EDX) is used to obtain elemental analysis of particles in liquid. A synthesized AlOOH particle is used as a model in the liquid SEM illustration.

In situ, in vivo, and in operando imaging and spectroscopy of liquids using microfluidics in vacuum

Journal Article Yu, Xiao-Ying - Journal of Vacuum Science and Technology A

This review offers a succinct overview of the development of a vacuum compatible microfluidic reactor, system for analysis at the liquid vacuum interface (SALVI), and its diverse applications in in situ, in vivo, and in operando imaging of liquid surfaces as well as the air-liquid (a-l), liquid-liquid (l-l), and solid-liquid (s-l) interfaces in the past decade. SALVI is one of the first microfluidics-based reactors that has enabled direct analysis of volatile liquids in vacuum surface tools such as scanning electron microscopy (SEM) and time-of-flight secondary ion mass spectrometry (ToF-SIMS). Its integration into ambient and vacuum spectroscopy and microscopy is illustrated.more »« less

Early Experiments with a New In Situ SEM Heating Technology

Conference Howe, Jane Y ; Walker, Larry R ; Allard, Jr, Lawrence Frederick ; ...

A new heating technology (Protochips, Inc.) has recently been introduced for in situ electron microscopy studies, including both TEM and SEM applications. Aduro{trademark} heater devices, fabricated using MEMS-based processing, offer numerous advantages for in situ SEM applications over those using a miniaturized furnace. The device supports a sample on a thin ceramic membrane that is directly heated by passing a current of a few mA, thereby also heating the sample. The entire heated area of the device is only 500um x 500um, so it is operated without circulating cooling water. The extremely small heated zone enables a rapid temperature responsemore »« less
