An experimental study was conducted to further our understanding about the fundamental physics of electrokinetic instability (EKI) and to explore the effectiveness to enhance fluid mixing inside a Y-shaped microchannel by manipulating convective EKI waves. The dependence of the critical voltage of applied static electric field to trig EKI to generate convective EKI waves on the conductivity rat...

Digital microfluidic systems (DMFS) are a class of lab-on-a-chip systems that manipulate individual droplets of chemicals on an array of electrodes. The biochemical analyses are performed by repeatedly moving, mixing, and splitting droplets on the electrodes. In this paper, we characterize the tree structure of biochemical analyses and identify their minimum resource requirements, towards the d...

ThefPDB\(" Planar Doped B_arrier| diode is a device consisting of a p doping spike \v .' between two" intrinsic layers and n ohmic contacts. This device has the advantages of controllable barrier height, diode capacitance and forward to reverse current ratio. A symmetrically designed PDB has an anti-symmetric current vs. voltage characteristic and is ideal for use as millimeter wave subharmonic...

The terahertz (THz) range is very attractive for astronomical observations. Spectroscopy and photometry of remote space objects in the THz range allows for a study of their chemical composition, because this range covers rotational lines from simple molecules and electron transition lines from atoms and ions. Heterodyne receivers, due to their high spectral resolution, in the THz range allows f...

Static mixers are in-line devices, which consist of motionless mixing elements, inserted in the given length of the pipe. Homogenization is attained by using the flow energy of the material to be mixed. The mixing effect depends on the continuous separation, distribution, and reunion of particles in the stream of material. There are various element designs available for mixing liquids and they ...

We present microwave ~30 GHz! measurements on aluminum superconducting hot-electron bolometer ~HEB! mixers. Aluminum HEB mixers have a lower superconducting transition temperature than niobium and niobium nitride devices, and are predicted to have improved sensitivity and require less local oscillator power. The devices studied consist of a narrow superconducting aluminum microbridge with conta...
