Bislang werden in vielen kulturellen Einrichtungen die Umweltbedingungen für vorhandene Bestände lediglich in regelmäßigen Intervallen händisch kontrolliert. Dieses pragmatische Vorgehen ist dem Umstand geschuldet, dass für ein Monitoring in Bestandsobjekten bislang nur kommerzielle Systeme zur Verfügung stehen, die auch aufgrund des Kostenfaktors meist nur in spezialisierten Anwendungsfällen zum Einsatz kommen. Basierend auf dieser Ausgangslage wurde ein Open-Source-Framework entwickelt, das mit günstiger Hardware betrieben werden kann. An der Universitätsbibliothek Bamberg wird dieses System seit September 2017 an unterschiedlichen Standorten erfolgreich eingesetzt. Monitoring of storage conditions in cultural institutionsThe Open Source Framework MonTreAL: Abstract: Currently, most cultural institutions monitor environmental storage conditions through mere manual measurements that are performed on a regular basis. The reason for this is that commercial storage monitoring solutions for an existing building are deployed only in specialized scenarios, partly due to their cost. Therefore, we developed an Open Source Framework operating on inexpensive off-the-shelf hardware. The university library of Bamberg is using this system successfully since September 2017 in different locations. [ABSTRACT FROM AUTHOR]

Many of the remarkable electrical and optical properties of organic semiconductors are governed by the interaction of electronic excitations with intra- and intermolecular vibrational modes. However, in specific systems this interaction is not understood in detail at a molecular level and this has been due, at least in part, to the lack of easy-to-use and widely available experimental probes of the structural dynamics. Here we demonstrate that thermal diffuse scattering in electron diffraction patterns from organic semiconductors, such as 6,13-bistriisopropyl-silylethynyl pentacene, allows the dominant lattice vibrational modes to be probed directly. The amplitude and direction of the dominant molecular motions were determined by comparison of the diffuse scattering with simulations and molecular dynamics calculations. Our widely applicable approach enables a much deeper understanding of the structural dynamics in a broad range of organic semiconductors. [ABSTRACT FROM AUTHOR]
