Description


Jeroen Jansen:"Measuring and Detecting the behaviour of Complex Systems"

Jeroen Jansen - Analytical ChemistryThe behaviour of complex systems, both alive and dead, needs to be measured to be understood and to be brought under control. Full understanding of how a disease perturbs human homeostasis requires comprehensive biochemical measurement, continuous measurement of different interacting compartments of an industrial process allows it to be operated on an economically much more competitive level. Thirdly, measuring different aspects of the quality of the river water that enters the Dutch delta will allow institutions like Rijkswaterstaat to give early and robust warnings on the specific pollutions that enter our country within this water as a serious danger to public health when not mitigated adequately.

These three examples all need the robust analytical technology (spectroscopy, spectrometry) that is at the core of IMM research, but it also needs a processing and analysis of the resulting data that will maximize the information that may be extracted for it. I will show that although the three examples are very different, we have developed data analysis methods for these issues that use many similar and convergent ideas. I will also show that our knowledge of  the analytical technology may be used to our advance in the analysis of this data, and therefore in the information and the value it contains.

Hans Elemans: "Encoding information into polymers"

Hans Elemans (Physical Organic and Supramolecular Chemistry)The amount of digital data produced in the world grows faster every year, and it is expected that within several decades the demand for data storage exceeds the availability of microchip-graded silicon. For this reason, new data storage concepts, in particular long-term (archiving), are being explored. In this context, data storage at the molecular level, on polymers, is highly appealing, since extremely high storage densities can be obtained. DNA is nature’s example of such a data storage material, but biopolymers are relatively vulnerable and suffer from limited temperature and solvent windows. Therefore, data storage on potentially more versatile and robust synthetic polymers is an exciting alternative.

In this talk I will show our current efforts and challenges of using a catalytic cage molecule (green) to ‘write’ oxygen atoms (red and purple) onto a synthetic polymeric alkene (yellow). Using a chiral catalyst, we expect to be able to carry out enantioselective oxidation reactions and use the thus formed (R,R) and (S,S) epoxides on the polymer chain as ‘0’ and ‘1’ values in a binary data storage system.
