Dripping, jetting and tip streaming have been studied up to a certain point separately by both
fluid mechanics and microfluidics communities, the former focusing on fundamental aspects …

For centuries, bubbles have fascinated artists, engineers, and scientists alike. In spite of
century-long research on them, new and often surprising bubble phenomena, features, and …

The depletion of high-grade and coarse-grain ores has led to an increasing demand for the
development of efficient separation technologies for low-grade and fine-grain ores …

Bubbles are always encountered for gas–liquid two-phase flow in microchannels, and have
potential applications in chemical engineering, polymer engineering, food engineering, and …

We provide a comprehensive and systematic description of the diverse microbubble
generation methods recently developed to satisfy emerging technological, pharmaceutical …

Microbubbles are increasingly being used in biomedical applications such as ultrasonic
