Strong interactions bubble/bubble and bubble/flow [PDF]
, 1994 The study of bubble dynamics in non-uniform flow fields is fundamental to the ability to predict or explain any cavitation effects in real flow fields. In this presentation we describe our recent contributions towards the fundamental understanding of bubble dynamics in non-uniform flow fields when large bubble deformations and bubble interactions are ...

Magnetic resonance imaging of oxygen microbubbles
Healthcare Technology Letters, 2019 Oxygen loaded microbubbles are being investigated as a means of reducing tumour hypoxia in order to improve response to cancer therapy. To optimise this approach, it is desirable to be able to measure changes in tissue oxygenation in real-time during ...

Applied Optics, 2019 Starting from a peculiar image observed below a bubble that is floating at a water–air interface, this paper analyzes several optical properties of these special types of refracting objects (termed bubble axicons). Using mainly geometrical optics, their relation to common axicons, the shadow-sausage effect, and elementary optical catastrophes (caustics)

Advanced Functional Materials, EarlyView.HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

We investigate the evolution and formation of double-layered vacuum bubbles during cosmological phase transitions with mltiple vacua. Using a semiclassical approach with initial velocity fluctuations, we demonstrate that under certain conditions, quantum effects do not lead to the formation of double-layered vacuum bubbles, while flyover transitions ...
