Researchers at our Uni, @Desy & European XFEL made a bubble 10 times smaller and at a pressure 100,000 times higher than an ordinary bubble. Then they used X-ray flash imaging to film it expanding at supersonic speed: ogy.de/e89d, doi.org/gkgqbm Nature Communications

An optical technique uses a laser pulse as a pump and collimated laser beam as a probe to generate nanosized gas bubbles in water go.aps.org/3hVkqcx

Professors who routinely take credit for work of students they do not support... ... today criticizing a university for taking credit for the work of a Nobel laureate they demoted...

In our last paper, we explore the use of ultrasound imaging to monitor and characterize fast fluid flows, the dissolution of tiny bubbles, and to track the propagation of shear waves induced by "bullet" jets in gelatin. Read more about it in Soft Matter. pubs.rsc.org/en/content/art…

"What is essential is invisible to the eye... and bubbles are not the exception" Check out our new paper in Experiments in Fluids Springer Nature on non-axysymmetric bubble jetting visualized by x-rays at the European XFEL. link.springer.com/article/10.100…

This acoustically driven bubble emits flashes of light during its periodic violent collapses and was imaged with single X-ray free-electron laser pulses European XFEL in our recent study: iopscience.iop.org/article/10.108… Juan Manuel Rosselló (JMR) Uni Göttingen #SBSL #cavitation #holography

The whispering gallery effect is behind cavitation-mediated high-speed jets ejected from curved liquid surfaces😮. Check out our new paper revealing how this works in International Journal of #Multiphase #Flow funded by @MSCActions and Humboldt-Stiftung. sciencedirect.com/science/articl…

Funny things happen when you create a bubble in a thin liquid layer: broad, mushroom & cylindrical jets + annular liquid sheet outflow, affected by the Rayleigh–Plateau and flapping shape instability. Check out our new paper. European Research Council (ERC) doi.org/10.1063/5.0209…
