We have successfully employed femtosecond laser to craft microstructures on polymeric substrate to imbed micro-mixiers. Since the laser pulse is ultra-short, the heat affected zone is not significant. Therefore the thermal melting damage is not as severe as that using continuous carbon dioxide laser. As a result, using femtosecond laser the fabrications of reproducible and defined micro-structu...

This paper describes an 84-116 GHz Nb/Al-oxide/Nb SIS mixer with multi-octave IF bandwidth and quantum-limited sensitivity. The mixer can be integrated with a three-stage 4-12 GHz HFET preamplifier or fitted with a coaxial connector for operation with an external isolator and IF amplifier. An 84-116 GHz receiver using the mixer with an integrated 4-12 GHz HFET preamplifier has a double sideband...

The purpose of this study was to explore the complex flow structure a novel active-type micromixer that based on concept of Wankle-type rotor. The characteristics of this micromixer are two folds; a rapid mixing of reagents in a limited space due to the generation of multiple vortices and a graduate increment in dynamic pressure as the mixed reagents is delivered to the output ports. Present mi...

The aim of this work is to introduce a novel statistical technique for quantifying the concentration field uniformity liquid-liquid mixing process within micro-scale chaotic pipeline. For illustration, microscale mixer in which inlet direction parallel unit designed by using pipeline with Baker map. Meanwhile, non-uniformity coefficient method adopted quantificationally instead qualitatively es...

We developed a confocal microscopic method for a quantitative evaluation of the mixing performance of a three-dimensional microfluidic mixer. We fabricated a microfluidic baker's transformation (MBT) mixer as a three-dimensional passive-type mixer for the efficient mixing of solutions. Although the MBT mixer is one type of ideal mixers, it is hard to evaluate its mixing performance, since the...

Computational fluid dynamic (CFD) simulation is an effective research approach for understanding velocity fields used in process and equipment intensification. It was found that mixer-settler used in rare earth metal extraction process was unsatisfying in large amount of liquid backlogged, high energy consumption and longtime settling process. In this paper, CFD simulations and experiment valid...

material balance around process has been conducted by using mixer output equations. a method based on mason's theory has been proposed to develop mixer output equations.

Identity Mixer is an anonymous credential system developed at IBM that allows users for instance to prove that they are over 18 years old without revealing their name or birthdate. This privacy-friendly technology is realized using zero-knowledge proofs. We describe a formal model of Identity Mixer that is well-suited for automated protocol verification tools in the spirit of black-box cryptogr...

This paper describes how to response of oscilloscopes, especially at low fre MHz to 1 GHz. The method uses the phas standard mixer calibrated by three-mixer reference phase. We describe basic principles obtained using a balanced mixer and a real-tim GHz BW).

A low-voltage and low-power RF mixer for WCDMA applications is presented. The paper presents a novel topology mixer that leads to a better performance in terms of isolation and power consumption for low supply voltage. The measuring results of the proposed mixer achieve: 7dB power conversion gain, 10.4dB double side band (DSB) noise figure, -2dBm input third-order intercept point (IIP3), and th...
