Needle-free jet injectors have been proposed as an alternative to injections with hypodermic
needles. Currently, a handful of commercial needle-free jet injectors already exist. However …

The dynamics of a cavitation bubble within a droplet is one of the hot research topics at
present. The present paper summarizes the research progress of bubble collapse within …

We analyze systematically the acoustic transients emitted during the collapse of a laser-
induced cavitation bubble for 0: 4 c 5: 2. c is the standoff parameter, the ratio of the distance …

Droplets splash when they impact dry, flat substrates above a critical velocity that depends
on parameters such as droplet size, viscosity, and air pressure. By imaging ethanol drops …

Drug diffusion within the skin with a needle-free micro-jet injection (NFI) device was
compared with two well-established delivery methods: topical application and solid needle …

This study investigated the fluid–tissue interaction of needle-free injection by evaluating the
dynamics of the cavity induced in body-tissue simulant and the resulting unsteady …

The background-oriented schlieren (BOS) technique with the physics-based optical flow
method (OF-BOS) is developed for measuring the pressure field of a laser-induced …

Cavitation occurs widely in nature and engineering and is a complex problem with
multiscale features in both time and space due to its associating violent oscillations. To …

We investigate the motion of a gas–liquid interface in a test tube induced by a large
acceleration via impulsive force. We conduct simple experiments in which the tube partially …

We experimentally examine a laser-induced underwater shock wave paying special
attention to the pressure impulse, the time integral of the pressure evolution. Plasma …
