How to turn the Fast-Track into a Fast-Track: Process integration for evaluation of the quality of Digital Health Applications (DiGAs) on the example of the German Fast-Track Process

In this paper, we address the research question of which integration points in the \textit{German Fast-Track process} are particularly well suited for the integration of evaluation platforms for digital health applications. For this purpose, possible integration points are first identified and then analyzed with the help of a utility analysis with regard to the posed research question. Finally, a recommendation for action is made based on the results of the conducted utility analysis

Group (III) Nitrides <i>M</i>[Mg₂Al₂N₄] (<i>M</i> = Ca, Sr, Ba, Eu) and Ba[Mg₂Ga₂N₄]Structural Relation and Nontypical Luminescence Properties of Eu²⁺ Doped Samples

The isotypic nitridomagnesoaluminates <i>M</i>[Mg₂Al₂N₄] (<i>M</i> = Ca,Sr, Ba,Eu) as well as a novel nitridomagnesogallate Ba­[Mg₂Ga₂N₄] have been synthesized by high-temperature reactions in arc-welded tantalum ampules. The crystal structures were solved and refined using single-crystal X-ray diffraction or powder X-ray diffraction data, respectively. All compounds crystallize in the UCr₄C₄-structure type (space group <i>I</i>4/<i>m</i> (no. 87), <i>Z</i> = 2, Ca­[Mg₂Al₂N₄]: <i>a</i> = 8.0655(11), <i>c</i> = 3.2857(7) Å, <i>wR</i>2 = 0.085 Sr­[Mg₂Al₂N₄]: <i>a</i> = 8.1008(11), <i>c</i> = 3.3269(7) Å, <i>wR</i>2 = 0.084; Eu­[Mg₂Al₂N₄]: <i>a</i> = 8.1539(12), <i>c</i> = 3.3430(7) Å, <i>wR</i>2 = 0.033; Ba­[Mg₂Al₂N₄]: <i>a</i> = 8.2602(9), <i>c</i> = 3.43198(19) Å, <i>wR</i>p = 0.031; Ba­[Mg₂Ga₂N₄]: <i>a</i> = 8.3654(12), <i>c</i> = 3.4411(7) Å, <i>wR</i>2 = 0.031) forming highly condensed anionic networks of disordered (Al/Mg)­N₄ and (Ga/Mg)­N₄ units, connected to each other by common edges and corners. The <i>M</i>²⁺ site is centered in <i>vierer</i> ring channels along [001] and coordinated in a cuboidal surrounding by N. Eu²⁺ doped samples of <i>M</i>[Mg₂Al₂N₄] (<i>M</i> = Ca,Sr,Ba) exhibit nontypical luminescence properties including trapped exciton emission in the red spectral region. These compounds widen the group of novel red-emitting materials such as Ca­[LiAl₃N₄]:Eu²⁺, Sr­[LiAl₃N₄]:Eu²⁺, or Sr­[Mg₃SiN₄]:Eu²⁺. Therefore, deep discussion of the observed anomalous luminescence is essential to understand the correlations between all these materials, which are fundamental to design narrow band luminescence of Eu²⁺ systems
