Determination of Nanoparticle and Microdroplet Parameters in Levitating Microdroplets of Suspension by Speckle Image Analysis Using Convolutional Neural Networks
Yaroslav Shopa, Kwasi Nyandey, Daniel Jakubczyk
The optical response of a suspension microdroplet is governed not only by the properties of the dispersed phase, but also by the finite size and optical structure of the droplet it…
Refractive Index, Its Chromatic Dispersion, and Thermal Coefficients of Four Less Common Glycols
Anastasiya Derkachova, Daniel Jakubczyk, Gennadiy Derkachov +1
We report comprehensive measurements of the refractive index as a function of wavelength and temperature for four less commonly studied glycols: pentaethylene glycol, hexaethylene…
A convolutional neural network technique for online tracking of the radius evolution of levitating evaporating microdroplets of pure liquids, liquid mixtures and suspensions
Kwasi Nyandey, Gennadiy Derkachov, Daniel Jakubczyk
We have used convolutional neural network in a classification task to track the radius evolution of levitating evaporating microdroplets of pure diethylene glycol, diethylene glyco…
A numerical toy model of Langevin dynamics provides real-time visualization of colloidal microdroplet evaporation
Gennadiy Derkachov, Tomasz Jakubczyk, Sima Alikhanzadeh-Arani +2
We have developed and tested a simplified but versatile numerical model of nanoparticles' aggregation using Langevin dynamics. The model is particularly capable of simulating aggre…
Up-Converting Luminescent Nanoparticles as Probes of Surface Dynamics in Single Evaporating Microdroplets of Suspension
Yaroslav Shopa, Maciej Kolwas, Daniel Jakubczyk +4
We have investigated the optically measurable properties of single evaporating microdroplets of suspensions containing up-converting luminescent nanoparticles (Gd2O3:Er3+), levitat…
