Here, we review the principle and applications of two recently developed methods: the capillary meniscus dynamometry (CMD) for measuring the surface tension of bubbles/drops, and the capillary bridge dynamometry (CBD) for quantifying the bubble/drop adhesion to solid surfaces. Both methods are based on a new data analysis protocol, which allows one to decouple the two components of non-isotropi...

Gas bubble behavior on a carbon anode in cryolite melt has been studied using see-through cell. The phenomena have growth, coalescence, detachment, and wetting during electrolysis. surface orientation affects behavior. Therefore, two different designs were tested, an with horizontal downward-facing vertical surface. At the anode, it was found that one large formed by growth coalescence of small...

Developing flexible and scalable methods for controlled assembly of nanomaterials remains a critical challenge in nanotechnology. In this article, we review the progress in assembly of nanostructures with a focus on the recently reported method utilizing a bubble expansion process to align one-dimensional nanostructures embedded in blown bubble films. This approach is general and enables effici...

Fill-in-the-bubble forms are widely used for surveys, election ballots, and standardized tests. In these and other scenarios, use of the forms comes with an implicit assumption that individuals’ bubble markings themselves are not identifying. This work challenges this assumption, demonstrating that fill-in-the-bubble forms could convey a respondent’s identity even in the absence of explicit ide...

Laser Doppler Velocimetry (LDV) has been employed to determine pseudo-turbulence characteristics of the flow field around bubble train forming in non-Newtonian caboxymethylcellulose (CMC) aqueous solution at low gas flow rate condition. The Reynolds stress and turbulent intensity of the liquid were investigated by means of Reynolds time-averaged method. The experimental results show that ax...

A sheared wet foam, which stores elastic energy in bubble deformations, relaxes stress through bubble rearrangements. The intermittency of bubble rearrangements in the foam leads to effectively stochastic drops in stress that are followed by periods of elastic increase. We investigate global characteristics of highly disordered foams over three decades of strain rate and almost two decades of s...

This paper unveils the basic mechanisms underlying rectified diffusion processes. The exact solution of the radial transport of species in both phases, gas and liquid, turns to be crucial to accurately predict the growthrate in the context of lithotripsy. The Direct Numerical Simulation of the temporal evolution of an spherical bubble is used to gain new insight on the effect of two phenomena: ...

Using a unique, near-field microscopy technique, fringe patterns and nanoparticle motions are visualized immediately following a nanofluid droplet deposition on a glass substrate in which an air bubble is entrapped. The nanofluid consists of DI-water, 0.10% Aluminum Oxide nanoparticles with an average diameter of 50 nm, and 0.0005% yellow-green polystyrene fluorescent particles of 1 μm diameter...
