Curriculum Vitae

Aljoscha Frede has studied Biochemical Engineering at the TU Dortmund University since 2013. He completed his bachelor thesis with the topic ‘Investment Cost Estimation of Heat Exchanger Types During Phases of Early Engineering’ at the Laboratory of Plant and Process Design. After a research internship at Sanyo Chemical Industries, Kyoto, Aljoscha graduated with the master thesis ‘Development of a Methodology for the Investigation of Industrial Liquid-Liquid Systems in a Stirred-Pulsed Extraction column’ at the Laboratory of Equipment Design. Since 2019 he works as a research associate at the Laboratory of Equipment Design.

Research

Micro reactors provide a high specific surface and low volume to enhance transport processes and enable safe handling of highly exothermic reactions. A drawback is that conventional sensor systems are rarely applicable in microchannels, which is why innovative and non-invasive solutions are desireable. The continuous, microfluidic calorimeter based on Seebeck elements allows the local and temporal resolution of heat flux profiles. Different operating modes of the reaction calorimeter provide thermodynamic and kinetic parameters of chemical reactions, which help to characterize reactors and aid reactor development.Explosionsansicht und Decisionmodule
