Predicting the structural colors of films of disordered photonic balls
Anna B. Stephenson, Ming Xiao, Victoria Hwang +8
Photonic balls are spheres tens of micrometers in diameter containing assemblies of nanoparticles or nanopores with a spacing comparable to the wavelength of light. When these nano…
Experimental determination of the propulsion matrix of the body of helical Magnetospirillum magneticum cells
Liu Yu, Lucas Le Nagard, Solomon Barkley +2
Helical-shaped magnetotactic bacteria provide a rare opportunity to precisely measure both the translational and rotational friction coefficients of micron-sized chiral particles.…
Designing angle-independent structural colors using Monte Carlo simulations of multiple scattering
Victoria Hwang, Anna B. Stephenson, Solomon Barkley +4
Disordered nanostructures with correlations on the scale of visible wavelengths can show angle-independent structural colors. These materials could replace dyes in some application…
Mechanical properties of model colloidal mono-crystals
Jean-Christophe Ono-Dit-Biot, Pierre Soulard, Solomon Barkley +4
We investigate the elastic and yielding properties of two dimensional defect-free mono-crystals made of highly monodisperse droplets. Crystals are compressed between two parallel b…
Large depth-of-field tracking of colloidal spheres in holographic microscopy by modeling the objective lens
Brian Leahy, Ronald Alexander, Caroline Martin +2
Holographic microscopy has developed into a powerful tool for 3D particle tracking, yielding nanometer-scale precision at high frame rates. However, current particle tracking algor…
Rearrangement of 2D aggregates of droplets under compression: signatures of the energy landscape from crystal to glass
Jean-Christophe Ono-dit-Biot, Pierre Soulard, Solomon Barkley +4
We study signatures of the energy landscape's evolution through the crystal-to-glass transition by compressing 2D finite aggregates of oil droplets. Droplets of two distinct sizes…
Holographic Microscopy with Python and HoloPy
Solomon Barkley, Thomas G. Dimiduk, Jerome Fung +5
A holographic microscope captures interference patterns, or holograms, that encode three-dimensional (3D) information about the object being viewed. Computation is essential to ext…
Predicting the size of droplets produced through Laplace pressure induced snap-off
Solomon Barkley, Samantha J. Scarfe, Eric R. Weeks +1
Laplace pressure driven snap-off is a technique that is used to produce droplets for emulsions and microfluidics purposes. Previous predictions of droplet size have assumed a quasi…
Snap-off production of monodisperse droplets
Solomon Barkley, Eric R. Weeks, Kari Dalnoki-Veress
We introduce a novel technique to produce monodisperse droplets through the snap-off mechanism. The methodology is simple, versatile, and requires no specialized or expensive compo…
