Polar curved polycyclic aromatic hydrocarbons in soot formation by Menon, Angiras, Martin, Jacob W., Bowal, Kimberly, Slavchov, Radomir I., Akroyd, Jethro, Mosbach, Sebastian, Kraft, Markus

“…The earliest (smallest size) onset of curvature integration was found to be a six ring PAH with at least one pentagonal ring. The σ bonding in the presence of pentagons led to curvature, however, the π bonding strongly favored a planar geometry delaying the onset of curvature and therefore the induction of a flexoelectric dipole moment. …”

Transient prediction of nanoparticle-laden droplet drying patterns through dynamic mode decomposition by Tanis-Kanbur, Melike Begum, Kumtepeli, Volkan, Kanbur, Baris Burak, Ren, Junheng, Duan, Fei

“…The developed data-driven approach has also achieved the acceptable prediction for the droplet diameter with less than 0.13% error and a coffee-ring thickness over a range of 2.0 to 6.7 μm. Moreover, the proposed machine learning algorithm can recognize the volume of the droplet liquid and the transition of the drying regime from one to another according to the predicted contact line and the droplet height.…”
