In order to investigate a PROX microreactor performance, two-dimensional modeling of the reacting flow between two parallel plates is performed through a finite volume method using an improved SIMPLE algorithm. A three-step surface kinetics including hydrogen oxidation, carbon monoxide oxidation and water-gas shift reaction is applied for a Pt-Fe/γ-Al2O3 catalyst and operating temperatures of a...

Rapid biocatalytic process development and intensification continues to be challenging with currently available methods. Chiral amino-alcohols are of particular interest as they represent key industrial synthons for the production of complex molecules and optically pure pharmaceuticals. (2S,3R)-2-amino-1,3,4-butanetriol (ABT), a building block for the synthesis of protease inhibitors and detoxi...

A facile integrated platform for proteome profiling was established, in which native proteins were online denatured and reduced within a heater, digested with an immobilized trypsin microreactor, and analyzed by microflow reversed-phase liquid chromatography with electrospray ionization tandem mass spectrometry (microRPLC-ESI-MS/MS). In comparison to the traditional off-line urea denaturation p...

A system level microreactor concept for hydrogen generation with Sodium Borohydride (NaBH4) is demonstrated. The uniqueness of the system is the transport and distribution feature of fuel (hydrogen) to the anode of the fuel cell without any external feed connectors and flow fields. The approach here is to use palladium film instead of feed connectors and the flow fields; palladium’s property to...

Sample handling procedures including protein digestion, glycopeptide enrichment, and deglycosylation have significant impact on the performance of glycoproteome analysis. Several glycoproteomic analysis systems were developed to integrate some of these sample preparation procedures. However, no microsystem integrates all of above three procedures together. In this work, we developed a glycoprot...

A compact membrane-based displacement immunoassay has been designed for rapid detection of explosive compounds 2,4,6-trinitrotoluene (TNT) and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) at high femtomole levels. The system consists of activated porous membranes, onto which either TNT or RDX antibodies are immobilized, that are inserted into microreactor columns, incorporated into a flow syst...

in this study, an efficient and green process for the synthesis of dihydropyrimidin-2(1h)-ones from aromatic benzaldehydes, ethyl acetoacetate and urea using al-mcm-41 as heterogeneous catalyst and microreactor under solvent-free conditions has been developed. the advantages of this method are easy work-up procedure, regeneration of the catalyst, clean and neutral reaction conditions.

Continuous-flow microstructured technologies are now recognized as promising alternatives to batch processing for organic photochemistry, especially when light emitting diodes (LEDs) employed sources. To evaluate and optimize productivity energetic efficiency, the knowledge of incident photon flux density is crucial. In this context, objectives present work dual: first, transfer classical actin...

Microscale technology has been increasingly used in chemical synthesis up to production scale, but in biocatalysis the implementation has been proceeding at a slower pace. In this work, the design of a low cost and versatile continuous flow enzyme microreactor is described that illustrates the potential of microfluidic reactors for both the development and characterization of biocatalytic proce...

A microfluidic reactor has been developed for rapid enhancement of protein digestion by constructing an alumina network within a poly(ethylene terephthalate) (PET) microchannel. Trypsin is stably immobilized in a sol-gel network on the PET channel surface after pretreatment, which produces a protein-resistant interface to reduce memory effects, as characterized by X-ray fluorescence spectrometr...
