研究单元“通过新型集成微传感器评估和控制微反应器中的动态局部工艺条件(PROMISE)”研究微型化电气、电化学和光学传感器的开发及其与技术微反应器和相关微系统的集成。通过使用这些传感器进行空间和时间分辨率的测量，结合详细的建模和数值模拟，目标是从根本上了解此类系统中局部输运和反应过程的动力学。在已有知识的基础上，应开发和制造优化的微系统，通过基于模型和传感器数据的过程控制，这些微系统可以在接近物理和化学最佳的情况下安全运行。为此，四个跨学科项目涉及(I)微流控通道中溶剂的蒸发，(Ii)新型膜-微反应器中的元素的多相催化直接合成过氧化氢，(Iii)药物化合物的多阶段连续光化学合成，以及(Iv)在近临界或超临界水介质中的水热条件下在陶瓷微反应器中合成金属氧化物纳米颗粒。

The research unit 'Assessing and Controlling Dynamic Local Process Conditions in Microreactors via Novel Integrated Microsensors (ProMiSe)' studies the development of miniaturised electrical, electrochemical and optical sensors and its integration into technical microreactors and related microsystems. By spatially and temporally resolved measurements using these sensors combined with detailed modelling and numerical simulation, fundamental understanding of the dynamics of local transport and reaction processes in such systems is targeted. Based on the gained knowledge, optimised microsystems shall be developed and fabricated, which can be operated safely close to the physical and chemical optimum via model and sensor data-based process control. For this, four interdisciplinary projects address (i) the evaporation of solvents in microfluidic channels, (ii) the heterogenously catalysed direct synthesis of hydrogen peroxide from the elements in a novel membrane-microreactor, (iii) multistage continuous photochemical syntheses of pharmaceutical compounds, and (iv) the synthesis of metal oxide nanoparticles in a ceramic microreactor under hydrothermal conditions in near critical or supercritical aqueous media.
