The mixing of analytes and reagents for a biological or chemical lab-on-a-chip is an important, yet difficult, microfluidic operation. As volumes approach the sub-nanoliter regime, the mixing of liquids is hindered by laminar flow conditions. An electrowetting-based linear-array droplet mixer has previously been reported. However, fixed geometric parameters and the presence of flow reversibilit...

Tfds paper explores, experimentally and theoretically, the problem of minimizing secondand third-order intermodulation distortion in diode mixers. A numerical technique is presented which can be used to cakulate internrodulation levels with unprecedented accuracy, and it is used to identify circuit and diode parameters which maximize dynamic range. It is shown that intermorhdation dktortion is ...

We are developing a symmetric gain optoelectronic mixer for chirped-AM laser detection and ranging systems (LADAR) operating in the “eye-safe” 1.55 m wavelength range. Signal processing of a chirped-AM LADAR system is simplified if the photodetector in the receiver is used as an optoelectronic mixer (OEM). Adding gain to the optoelectronic mixer allows the following transimpedance amplifier’s ...

Several dry processing techniques are assessed to elaborate metallic nanocomposite powders dedicated powder-bed-based (PBB) additive manufacturing as laser-powder bed fusion (L-PBF) and Binder Jetting (BJ). Electrostatic assembly of nanosized silicon carbide (35 nm) particles at the surface gas atomized aluminium (15-53 ?m) is performed using mixers covering a range mixing energy from rotative ...
