Universal shape and pressure inside bubbles appearing in van der Waals heterostructures [PDF]
Trapped substances between a two-dimensional (2D) crystal and an atomically flat substrate lead to the formation of bubbles. Their size, shape and internal pressure are determined by the competition between van der Waals attraction of the crystal to the ...

Machine-Learned Free Energy Surfaces for Capillary Condensation and Evaporation in Mesopores
Using molecular simulations, we study the processes of capillary condensation and capillary evaporation in model mesopores. To determine the phase transition pathway, as well as the corresponding free energy profile, we carry out enhanced sampling ...

In this study, a theoretical model for prediction of bubbling regimes in bubble formation from a single submerged orifice has been developed. The model takes into account both chamber pressure fluctuations, and bubble–bubble and bubble–wall interactions on bubbling regimes.

Bubble mass transfer is a common phenomenon in industrial applications. In this paper, bubble dynamics in both still and turbulent flow were introduced first, followed by the mass transfer properties of a single bubble and bubble swarms.

In this paper, the extended finite element method (XFEM) is first applied to account for the weak discontinuity of the axisymmetric electrostatic field. Firstly, the interface between two materials in an element is described by the level set method.

We present an extrapolative model of bubbles. In the model, many investors form their demand for a risky asset by weighing two signals—an average of the asset’s past price changes and the asset’s degree of overvaluation.

Control of bubble size and bubble number in bubble electrospinning
AbstractThe surface tension of a bubble depends upon its size; a smaller bubble requires a smaller electronic force for fabrication of ultrafine fibers using bubble electrospinning. The electronic field triggers rupture of interacted bubbles to form daughter bubble cascades, so a very low voltage is needed for nanofiber fabrication.

Heat load and deuterium plasma effects on SPS and WSP tungsten
Tungsten is a prime choice for armor material in future nuclear fusion devices. For the realization of fusion, it is necessary to address issues related to the plasma–armor interactions. In this work, several types of tungsten material were studied, i.e.

To investigate the effect of frother concentration on bubbles and their tail vortex zone characteristics in flotation is an important prerequisite for predicting the probability of particle coiling in the trailing vortex zone of flotation bubbles.
