3 What is NANOSLAB about? NANOSLAB is designed to study the aggregation of zeolite NANOSLABS into bulk zeolite. The obtained information will serve to optimize the zeolite synthesis on earth to improve the properties of the zeolite product. For this, samples of clear solution containing the NANOSLABS will be heated to 95°C. This induces the aggregation process of the NANOSLABS into successively larger units. To obtain series of samples corresponding to different stages of the process, sample cartidges will be heated with a time delay. A quenching of all samples will then interrupt the aggregation process after different treatment times. A detailed analysis of the particle populations in the samples after retrieval will allow determination of the aggregation kinetics and will show the effect of convection and sedimentation on the formation of zeolite from NANOSLABS.

5 How are NANOSLABS prepared?

6 Hardware items 10 ensembles of 3 sample cells (30 samples) Ensembles are mounted in a Sample unit grid (frame) with cover Bottom cover plate Handle (use handle from MSG airlock top lid) Thumb screws (use from MSG) E-box Harness There is NO transport container needed Where are the NANOSLABS treated? The NANOSLAB experiment

7 Where are the NANOSLABS treated? The NANOSLAB experiment

8 Where are the NANOSLABS treated? The NANOSLAB experiment

9 Where are the NANOSLABS treated? The NANOSLAB experiment

10 Where are the NANOSLABS treated? The NANOSLAB experiment

11 Short Experiment Flow Remove from stowage, visual inspection Install experiment inside MSG Activate experiment Ensembles sequentially heat up to 95°and are kept at that temperature (heat up time = 29 minutes) After 48 hrs, de-activate heaters....

Please do not overcook them!

13 Short Experiment Flow Remove from stowage, visual inspection Install experiment inside MSG Activate experiment Ensembles sequentially heat up to 95°and are kept at that temperature (heat up time = 29 minutes) After 48 hrs, de-activate heaters Quench all ensembles at same time (mechanism) Let experiment cool down (5.8 minutes to 60°C – 15 minutes total) Remove from MSG Where are the NANOSLABS treated? The NANOSLAB experiment

14 What are the meríts of NANOSLAB? Knowledge of the effects of convection and sedimentation on the aggregation of NANOSLABS will help during the development of tailor made zeolite materials like: Highly catalytically active zeolite coatings with high specifity Highly catalytically active zeolite coatings with high specifity Highly catalytically active zeolite membranes with high specifity and separation performance Highly catalytically active zeolite membranes with high specifity and separation performance Zeolite Sensors Zeolite electro-optical devices because: There is nothing a zeolite will not do (once you convinced it to do it….)
