Recent Advances in Ultrafast Real-time Imaging of Sonoprocessing Advanced Materials: Jiawei Mi1; 1University of Hull
Applying ultrasonic waves in the syntheses or manufacturing of materials is generally termed as sonoprocessing. It involves many nonlinear dynamic phenomena and processes, for example alternating pressure induced cavitation bubbles dynamics, acoustic streaming flow, liquid-bubble-solid interactions, etc. Many fundamental issues or governing laws in these processes are either not fully understood or not fully quantified. It is due to mainly the difficulty in directly observing the dynamic phenomena in-situ and in real time operando conditions. Here, we report our very recent outcomes from operando study of the dynamics of nano/microparticles dispersion and exfoliation of 2D materials under ultrasound. We used the ultrafast synchrotron X-ray and MHz imaging capability available at the EU X-ray free electron laser facility. The unique world leading capability allow us to observe directly the interactions of liquid, bubble and solid particles, providing essential data for understanding the ns scale microfluidic dynamics in sonoprocessing of materials.

Real-time Plasmon-Enhanced Colorimetric Imaging: Brian Abbey1; 1La Trobe University
Recently we have demonstrated a new technique for imaging biological samples termed ‘colorimetric histology’ (Balaur et al., Nature, 2021) and have combined this with quantitative phase imaging to achieve unprecedented sensitivity to variations in sample structure and composition (Cadenazzi et al., Nature Photonics, 2021). Here we describe and demonstrate the extension of these methods to the time-resolved imaging of nanoscale processes including molecular adhesion and the formation of self-assembled monolayers. This talk will discuss the unprecedented, label-free, sensitivity that it is possible to achieve using colorimetric histology and provide a summary of its potential applications in the context of real-time imaging.

Behavior of Plastic Ashes in Gasification Environments: Jinichiro Nakano1; Kristin Tippey1; Anna Nakano1; Hugh Thomas1; Ömer Doğan1; 1US Department of Energy - National Engergy Technology Laboratory
Plastic upscaling/recycling is one of the most effective ways to decarbonize the chemical industries. Gasification is a chemical recycling path that enables carbon renewal at elevated temperatures by breaking waste plastics into basic constituents. Energy input may be offset by heat generation as a process byproduct. Significant energy savings in recycling plastics would be possible, not only compared to the mechanical recycling, but also to the traditional gasification because plastics carry higher heating values. This work reports ash compositions from various common plastics and their behavior at high temperatures. While most ash tends to be rich in alkaline earth metals, some such as low-density polyethylene (LDPE) and polypropylene (PP) ash indicate very high concentrations of Ti up to 95 wt.%. In-situ behavior of select ash/slag in simulated gasification environments (up to 1500 °C in 64%CO-36%CO2) will be examined using the customized high-temperature environmental confocal scanning laser microscope.
