Fine and Hyperfine Interactions with Multi-level Spin Relaxation of the purified Giese-Salt in Veterinary Medicine: Prussian Blue Compound Ammonium-Ferric-Hexacyano-Ferrate

Ammonium ferric hexacyanoferrate is a veterinary-medical milestone and antidote against radiocesium, well-known as Giese-salt after the Chernobyl disaster fed to domestic and wild animals, which shows even a rich interplay of properties in nanostructural chemistry and ferromagnetism. Among the broad analytical techniques, the ambivalence of macroscopic micrometer-sized agglomerates and nanoparticle sizes, a suggested enlarged Fe(II)$-$C$\equiv$N$-$Fe(III) bond length by Fe K-edge XAFS results and multi-level spin relaxation in $^{57}$Fe M\"ossbauer spectroscopy are highlighted. This sets this underestimated compound in a new light, e.g., for modern biomedicine and biofunctionality, extending its essential importance in addition to hypothetical future nuclear incidents

Escape Room combined with European Board Game Concepts for self-adjusted Challenge Levels: An educational Eurogame Escape Room in Physics

We present an educational escape room in physics (ERP) covering the main disciplines of physics as taught in the education of neighboring sciences, in this case veterinary medicine, extended by a European board game system of victory points (VP). The puzzles in physics are mandatory to master the ERP requiring to be solved in a sequential order. In our study, we show the growth of knowledge by knowledge-transfer cards separated into disciplines of physics as demonstrated by critical exemplary questions of test groups. Tactical secondary puzzles, the so called \textit{Eurogame puzzles} (EPs), are able to be solved in parallel in any arbitrary and independent sequence, allowing a self-adjusted challenge autolevelled by the students by choice. The motivation is improved by a scoring list to solve, at least, a few optional EPs as additional game-like adventure and challenge collecting VP. A second part of the study demonstrates the attraction of the introduced European board game concept as an important tool for gamificiation and open-by-choice EPs not being necessarily related to physics directly. EPs are able to smooth the contrast of playing games and learning, providing an additional bridge to overcome the fear of physics. A strong advantage is the flexibility of the European board concept, choosing from a broad range of optional EPs to fascinate and motivate students taking into account individual preferences improving escape rooms by decision-making skills. The concept is able be applied to every escape room independent of the taught subject or topic.
