Workshop on JetCutter Technology and Digital Image Analysis

On December 15th to 16th a practical workshop on the JetCutter Technology and Digital Image Analysis was organized by the Institute of Materials Research of the German Aerospace Center (DLR) in Cologne.

Several PhD students and postdocs from Hamburg University of Technology, Koç University from Istanbul, Turkey and Mines ParisTech from Sophia Antipolis, France came to participate in the workshop. All of them are directly involved in the H2020 project “NanoHybrids”.

The workshop started with the JetCutter Technology. In the beginning just little theory was discussed including the cutting geometry

explained by Philipp Niemeyer from DLR. The main focus was based on practical work with the JetCutter device. Participants were asked to bring their individual recipes and polysaccharide solutions. After some quick pre-testing the JetCutter process parameters were estimated, adjusted and verified by experiments. Beautiful results were obtained from sodium-alginate solutions as well as from cellulose/EMIMAc solutions. Beads with diameters between 400 and 2000 µm were produced. Those diameters were perfectly matching most of the requirements of the NanoHybrids project. Production rates around 20 kg/h were obtained and verified the technology readiness level around TRL 5. Some of those samples were post-treated at DLR and are going to be dried with super critical CO2 these days.

After the introduction to the Jet CutterTechnology was finished the workshop focused on the Digital Image Analysis. In charge of Victor Baudron from TUHH an experiment on the emulsion gelation technology was performed. This was followed by explanations of theory and the custom made software. Perfect examples were shown as well as challenges in the digital image analysis.

The aim of the workshop to show the potential of the JetCutter technology to “NanoHybrids” members was successfully done. It was shown that the unique and promising technology fits the needs of high productivity and reproducibility. Within the workshop a configuration of tools and equipment was shown to efficiently reach the NanoHybrids requirements and deliverables of aerogel bead amounts between 20 and 60 L.

Participants were encouraged for further experiments and collaborations with DLR.
