A novel impedance-based thermoplastic flow-through immunosensor is presented which integrates a porous polymer monolith capture element with an interdigitated electrode array (IDA). The technique employs a volumetric impedance sensing zone and a direct assay with secondary antibody labeled gold nanoparticles (Ab-AuNP). The captured gold nanoparticles are silver enhanced causing an impedance dro...

Here we demonstrate for the first time, a novel fabrication method to integrate microarray spotting technology with in-situ fabricated highly porous polymer monoliths in a microfluidic platform as a high-thourouput multiplex biosensor. Parallel screening of low-abundance analytes from a complex fluidic sample can be realized by covalent linkage of various capture antibodies in discretely define...

The monolithic column is a single piece of a continuous rigid porous polymer that possesses an interconnected skeletal structure and contains pores. According to their components, monolithic materials can be divided into organic polymer-based monoliths and inorganic silica-based monoliths. This review focuses on silica-based monolith with special emphasis on the preparation. Moreover, this revi...

Abstract For NO x removal from diesel exhaust, the selective catalytic reduction (SCR) is most common abatement technology. However, low engine load scenarios such as city driving and cold start phases demand efficient clearly below 200 °C, which difficult to achieve with SCR. Hence, this work investigates potential of low-temperature H 2 in exhaust. A monolithic Pt/WO /ZrO catalyst, recently r...

Lateral subsurface flow (LSF) is a phenomenon frequently occurring in the field induced by local water saturation along horizon boundaries under nonequilibrium conditions. However, observations of LSF undisturbed soils controlled irrigation laboratory are limited but needed for model improvement, prediction, and quantification LSF. We present method extracting an soil monolith boundary introduc...

Highly transient engine-out emissions imply significant challenges for the optimization and control of automotive aftertreatment systems, motivating studies effects flow pulsations on system behavior. In this work, an axisymmetric with a first-order reaction in monolith section is chosen to demonstrate role time-averaged conversion at exit. Reactive computational fluid dynamics simulations unde...
