We report a self-contained electrochemical enzyme linked immunosorbent assay in microchannel devices constructed from low temperature co-fired ceramic with screen-printed gold for fast and sensitive assays. No one has previously reported a device constructed from these materials for combined immobilization and electrochemical detection. These low temperature co-fired ceramic microchannel device...

We propose here a new method for continuous concentration and classification of particles in microfluidic devices, named hydrodynamic filtration. When a particle is flowing in a microchannel, the center position of the particle cannot be present in a certain distance from sidewalls, which is equal to the particle radius. The proposed method utilizes this fact, and is performed using a microchan...

A typical MCP consists of about 10,000,000 closely packed channels of common diameter which are formed by drawing, etching, or firing in hydrogen, a lead glass matrix. Typically, the diameter of each channel is ~ 10 microns. Each channel acts as an independent, continuous dinode photomultiplier. In astronomy, and in the many other fields that use MCPs, the detectors are generally used for disto...

In this work\ a comparative investigation of jet impingement and microchannel cooling is presented[ The thermal performance of each technology evaluated at the respective optimal condition is compared to each other with the target dimension as a main parameter[ It is revealed that the microchannel cooling is preferable for a target dimension smaller than 9[96 by 9[96 m\ while the jet impingemen...

Molecular communication is a promising technique for microchannel systems. In this paper, various microchannel molecular communication schemes are simulated and analyzed using information theory, including molecular motors and Brownian motion with drift. Results suggest Brownian motion with drift can deliver excellent performance, depending on the drift velocity.

This study presents a theoretical investigation of a flexible, electromagnetically controlled microchannel transport system (i.e., controllable micropump) utilizing a soft magnetorheological elastomer. A two-dimensional time-dependent model using a coupled fluid-solid-magnetic analysis is developed to conduct a parametric study on a system which consists of a flexible channel and valves. Effect...

Thermal management has become a critical issue for high heat flux electronics and energy systems. Integrated two-phase microchannel liquid-cooling technology has been envisioned as a promising solution, but with great challenges in flow instability. In this work, silicon nanowires were synthesized in situ in parallel silicon microchannel arrays for the first time to suppress the flow instabilit...

This paper describes the heat and mass transfer in a square microchannel that is heated from one side. This microchannel represents a reaction channel in a microreactor that is used to study the kinetics of the catalytic partial oxidation of methane. The microchannel is contained in a silicon wafer and is covered by a thin silicon sheet. At the top side of this sheet, heating elements are prese...

This paper presents the refrigerant adiabatic upward flow in the vertical header of microchannel heat exchanger and its effect on distribution. R410A is circulated into the header through the microchannel tubes (5 or 10 tubes) in the bottom pass and exits through tubes (5 or 10 tubes) in the top pass representing flow in the heat pump mode of reversible systems. Three circular headers were expl...
