Reduction of droplet volume by controlling actuating waveforms in inkjet printing for micro-pattern formation (2009, background): “Chen and Basaran (2002) investigated formation of small water– glycerin droplets and observed a tongue of liquid moving at a higher velocity than the nearby liquid by applying a successive negative and positive driving wave.”
Controlled impact of a disk on a water surface: cavity dynamics (2008, background): “…of industrial applications, drop impact and the subsequent void formation are crucial in pyrometallurgy (Liow et al. (1996); Morton et al. (2000)), in the food industry, and in the context of ink-jet printing (Le (1998); Chen & Basaran (2002); de Jong et al. (2006a); de Jong et al. (2006b)).”
Drop on demand in a microfluidic chip (2008, background): “Each of these aspects is sensitive to the design geometry and the actuation process [52, 54-59].”
Visualization of drop-on-demand inkjet: Drop formation and deposition (2006, methodology): “However, even though ultrafast digital systems [14, 69] were used, the maximum number of frames for one single process was too low for de tailed analysis of the entire drop formation process.”
ENGINEERING FLOWS IN SMALL DEVICES (2004, methodology): “For example, pulsing the pressure field using a piezoelectric sleeve has been used advantageously in improving ink-jet designs for the production of droplets with diameters in the tens of microns range (e.g., Chen & Basaran 2002).”
Inkjet printing of conductive materials: a review (2012, methodology): “There have been several experimental studies on waveform design but the results of these are often print head specific (Hwang et al., 2007; Kwon, 2010; Dong et al., 2006b; Chen and Basaran, 2002).”
Dynamics and breakup of a contracting liquid filament (2004, background): “…surface on which a liquid drop is placed is oscillated to eject a portion of the drop (Wilkes & Basaran 2001; James et al. 2003) or drops are generated from a drop-on-demand inkjet nozzle (Döring 1982; Chen & Basaran 2002), symmetrical filaments can be produced for liquids of arbitrary viscosity.”
