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 …

Cavitation bubble dynamics include the releasing shock wave, violent jet impact, and
extremely local high temperature at the collapse phase. Notably, in the case of a bubble …

Integrated photoelasticity is investigated for a soft material subjected to a three-dimensional
stress state with large deformation. Our measurement target is designed based on the …

Ultrasound is a ubiquitous technology in medicine for screening, diagnosis, and treatment of
disease. The functionality and efficacy of different ultrasound modes relies strongly on our …

Hertzian contact of a rigid sphere and a highly deformable soft solid is investigated using
integrated photoelasticity. The experiments are performed by pressing a styrene sphere of …

When a cavitation bubble re-expands near the surface of a liquid, an axisymmetric crown
forms around the jet that is initially produced. Controlling this crown is essential if the first jet …

This study systematically investigates the flow birefringence of cellulose nanocrystal (CNC)
suspensions. The aim is to clarify the importance of the stress component along the …

The birefringence response of aqueous cellulose nanocrystal (CNC) suspensions in a two-
dimensional laminar flow is measured and studied. The suspensions have CNC …

This work explores bubble laser technology as an alternative to needles in injection systems
for vaccination, cancer treatment, insulin delivery, and catheter hygiene. The technology …

Focused jets have been widely studied owing to the abundance of attractive flow
phenomena and industrial applications, whereas annular focused jets are less studied. This …
