A novel, multimicrocapillary flow reactor (MμCFR) was constructed and applied to a series of sensitized photoadditions involving 2(5H)-furanones. The reactor allowed for rapid and energy-, time-, and space-efficient sensitizer screening, process optimization, validation, scale-up, and library synthesis.

Homodispersed 1.8 nm gold nanoparticles were obtained reproducibly in high yields using the classical Turkevich protocol at a high concentration in a continuous flow capillary reactor. The microfluidic reactor made from commercially available items permitted short mixing, heating and quenching times which are the key parameters of this synthesis.

Prospect measurements of neutrino oscillations with reactor neutrinos are reviewed in this document. The following items are described: neutrinos oscillations status, reactor neutrino experimental strategy, impact of uncertainties on the neutrino oscillation sensitivity and, finally, the experiments in the field. This is the synthesis of the talk delivered during the NOW2006 conference at Otran...

The length of time that the solution remains inside the reactor channels—the residence time—can be greatly reduced by adjusting the length of the channels in flow microreactors. This feature is extremely useful in controlling reactive species. Unstable short-lived reactive species can be generated and transferred to another location to be used in the next reaction before they decompose. Therefo...

Adaptation of network weights using LevenbergMarquardt (LM) training algorithm was proposed as a mechanism to improve the performance of Artificial Neural Networks (ANN) in modeling the Tennessee Eastman (TE) chemical process reactor. A Neural Network of the AutoRegressive, eXternal (NNARX) input model was developed. Four sub-models for the TE reactor were built. They are: the reactor level, th...

In this manuscript, a two-input two-output (TITO) control strategy for an exothermic continuous chemical reactor is presented. The tasks of the are related to temperature regulation by standard proportional-integral (PI) controller. selected set point increases productivity due effect and prevents potential thermal runaway, until it reaches isothermal operating conditions. Then, optimal control...

A rapid and modular continuous flow synthesis of highly functionalized fluorinated pyrazoles and pyrazolines has been developed. Flowing fluorinated amines through sequential reactor coils mediates diazoalkane formation and [3+2] cycloaddition to generate more than 30 azoles in a telescoped fashion. Pyrazole cores are then sequentially modified through additional reactor modules performing N-al...

Study of reactor modeling in the process aniline synthesis. Every year demand for is growing all over world, and, accordingly, capacity its production. The areas consumption this product are different: production isocyanates used industry building materials (foams, decorative parts, pipe insulation, etc.), shoe industry, additives to motor fuels; pharmaceutical preparations; organic dyes and pi...

Controlled synthesis of both single-walled carbon nanotube and carbon nanowire networks using the same CVD reactor and Fe/Al(2)O(3) catalyst by slightly altering the hydrogenation and temperature conditions is demonstrated. Structural, bonding and electrical characterization using SEM, TEM, Raman spectroscopy, and temperature-dependent resistivity measurements suggest that the nanotubes are of ...
