Shock Wave Emissions of a Sonoluminescing Bubble
, 1998 A single bubble in water is excited by a standing ultrasound wave. At high intensity the bubble starts to emit light. Together with the emitted light pulse, a shock wave is generated in the liquid at collapse time.

Advanced Functional Materials, EarlyView.Oct4‐nanoscript, a biomimetic nanoparticle‐based artificial transcription factor, precisely regulates cellular rejuvenation by activating Oct4 target genes, restoring epigenetic marks, and reducing DNA damage. In a progeria model, it effectively rescued aging‐associated pathologies and extended lifespan.

Dynamics of laser-induced bubble pairs
Journal of Fluid Mechanics, 2015 The interaction of two laser-induced bubbles in bulk water is investigated. The strength and direction of the emerging liquid jets can be controlled by adjusting the relative bubble positions, the time difference between bubble generation, and the laser ...

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 ...

Blowing bubbles: Dermoscopy of bubble hair
International Journal of Trichology, 2017 Exposing wet hair to high temperatures can create gas bubbles within the hair shaft, leading to brittle, dry hairs in a disorder known as bubble hair abnormality. We present a case of a 61-year-old woman who presented for hair breakage over her crown. She regularly dried her damp hair with a blow dryer.

Ultrasonic Healing of Plastrons
Advanced ScienceSuperhydrophobic surfaces (SHS) exhibit a pronounced ability to resist wetting. When immersed in water, water does not penetrate between the microstructures of the SHS. Instead, a thin layer of trapped gas remains, i.e., plastron. This fractional wetting
