Operando X-ray spectroscopy shows what happens in each single part of a working catalyst.Nature Catalysis: Operando X-ray spectro-scopy shows 3D view of catalysts in action

Catalysts accelerate chemical reactions in order to reduce energy consumption and undesired by-products as in emission control. “To really understand how these materials function, we need to take a look inside the reactor when the catalyst is working,” says Thomas Sheppard. With a newly developed setup, the operando X-ray spectroscopy, his team succeeded in tracking the complex 3D structure of an active catalyst in cooperation with the Swiss Light Source of Paul Scherrer Institute in Switzerland and the European Synchrotron Radiation Facility in France. The results are published in Nature Catalysis.

Biodegradable displays adhere to the skinCompostable displays for sustainable, environmentally friendly electronics

Electronic waste that is biodegradable? For printed displays, it has become a reality. Gerardo Hernandez-Sosa's group used biocompatible materials of mainly natural origin for this purpose. The inkjet printing process also enables customised, cost-effective and material-efficient production with high throughput. Sealing with gelatine makes the displays adaptable and adherent. Thus, they can be worn directly on the skin and are suitable for use e.g. in medical diagnosis or food packaging. The researchers published their results in the Journal of Materials Chemistry.

Catalyst used in emissions control are structurally complex. Multiscale tomography can address these structures from the macroscale to the nanoscale.German Research Foundation funds new Collaborative Research Centre TrackAct

Heterogeneous catalysis plays an important role in emission control, converting harmful pollutants to inert products: e.g. nitric oxids to nitrogen. However, the relationship between catalyst structure, function, and the mechanisms which drive such chemical reactions are highly complex, and still largely unknown. Thus, the goal of the new SFB is to get an holistic understanding of catalytic processes. As PI of a subproject, Thomas Sheppard will derive structure-activity relationships and relate local structure observations to catalyst performance using synchrotron-radiation-based hard X-ray microscopy and (electron) tomography.

Science WalkYIN Day 2020 with Prof. Rebecca Harrington - a successful hybrid event

The two highlights of the day were a science walk through the Hardtwald and an invited talk by YIN alumna Rebecca Harrington, professor at the Ruhr University Bochum. During the walk, YIN members and alumni presented their research in short pitches. Between each station, there was plenty of open space for discussion and networking. The first ideas for joined projects have, thus, been born. Rebecca Harrington’s talk on “Using a-typical seismic signals to understand the earthquake problem” concluded the afternoon's online program. A-typical earthquakes occur in unusual depths in the fault zone or away from active plate boundaries.

DFG-KodexYIN on the Project Advisory Board for the Implementation of the DFG Code of Conduct

The freedom of science is closely linked to responsibility and a commitment to scientific integrity and honesty. To this effect, the DFG has adopted a Code of Conduct with Guidelines for Safeguarding Good Research Practice. Universities and research institutions must implement these guidelines in order to qualify for further DFG funding. KIT now faces the task of adapting its statutes in terms of content and language by July 31, 2021. With Hartwig Anzt and Manuel Hinterstein, two YIN representatives monitor this change as part of the advisory board of the implementation project.

Mehle auf InsektenbasisAlternative protein source: flours from insect powder

Larvae of mealworms are rich in protein and have a CO2 balance twice as good as beef. Processed as powder and used as ingredient for traditional foods like bread, it is conceivable that they may be introduced on the German market, so Azad Emin. His team uses an extrusion process similar to that used for pasta. This can be specifically adapted so that insect flours, despite their higher protein and fat content, do not differ noticeably in taste, baking properties, and texture from conventional baking flours. At the same time, the process deactivates enzymes, removes residues, and can promote improved digestibility.

Hartwig Anzt, UT/KITFaster algorithms through multiprecision format

Multiprecision algorithms mix different precision formats to get faster computation run-time – currently saving up to 20%. While preserving double-precision quality in the output, intermediate calculations can run on a lower precision format. In memory bound algorithms, where the data transfer volume slows down the computation, more-compact precision formats can reduce the pressure on the memory bandwidth. Hence, decoupling of the arithmetic from the memory format is essential, says Hartwig Anzt in a Let’s Talk Exascale podcast. As multiprecision algorithms are not limited to special-function units, a strong focus lies on interoperability.

Offering full reproducibility and open source code, software contributions can be more beneficial to the scientific community than classical publications. However, they do not count towards impact metrics like the H-index. To instigate a change, software contributions could become acceptable as a full-value conference submission to be included in the proceedings after an additional independent review. In the blog Better Scientific Software, Hartwig Anzt argues that a community-based assessment would reduce the workload of the independent reviewer and ensure a very high quality.

Inkjet-Printed Perovskite PhotovoltaicsPerovskite photovoltaics – flexible in shape and color

In the project PRINTPERO, German and Greek researchers have teamed up with industrial partners to develop printed perovskite semi-conductors for building integrated photovoltaics. In ACS Applied Energy Materials, they report how a strong color perception can be achieved by inkjet-printing luminescent layers on top of the Perovskite solar cells at a relatively small (∼17%) reduction of power conversion efficiency. Gerardo Hernandez-Sosa and Ulrich Paetzold, both YIN members, added their know-how in electronic printing and photovoltaics respectively.
