Drop-on-demand inkjet-based cell printing with 30-μm nozzle diameter for cell-level accuracy.
Biomicrofluidics, 2016 We present drop-on-demand inkjet-based mammalian cell printing with a 30-μm nozzle diameter for cell-level accuracy. High-speed imaging techniques have been used to analyze the go-and-stop movement of cells inside the nozzle under a pulsed pressure ...

Global Subsonic and Subsonic-Sonic Flows through Infinitely Long Axially Symmetric Nozzles [PDF]
arXiv, 2009 In this paper, we establish existence of global subsonic and subsonic-sonic flows through infinitely long axially symmetric nozzles by combining variational method, various elliptic estimates and a compensated compactness method. More precisely, it is shown that there exist global subsonic flows in nozzles for incoming mass flux less than a critical ...

Global Stability of Steady Transonic Euler Shocks in Quasi-One-Dimensional Nozzles [PDF]
arXiv, 2011 We prove global in time dynamical stability of steady transonic shock solutions in divergent quasi-one-dimensional nozzles. We assume neither the smallness of the relative slope of the nozzle nor the weakness of the shock. Key ingredients of the proof are an exponentially decaying energy estimate for a linearized problem together with methods from ...
