High performance simulations of electrokinetic flow and transport in microfluidic chips
(Elsevier Science Sa, 2009-12)
This article discusses high performance numerical simulations of electrokinetic flow and transport phenomena in microfluidic chips. Modeling grounds on conservation equations of mass, momentum and electric charge in the ...
Newly designed dual-mode electrochemical sensor onto a single polydimethylsiloxane-based chip
(2021-01-01)
Here we present a planar polydimethylsiloxane (PDMS)-based millifluidic device in which the channel (at a serpentine-shape) and a new design of electrochemical sensor (dual-mode detection) are assembled into a single chip. ...
Influence of the tool edge geometry on specific cutting energy at high-speed cutting
(2007-07-01)
This paper presents specific cutting energy measurements as a function of the cutting speed and tool cutting edge geometry. The experimental work was carried out on a vertical CNC machining center with 7,500 rpm spindle ...
