These results can be set in a historical context and help to confirm art historical interpretations. Proofs of certain pigments can be used for dating purposes and may reveal if the artist used not only local but also imported materials. A pilot study of two Chinese reverse glass paintings from the late 19th (Yingying and Hongniang) and early 20th centuries (The Archer) was performed using a multi-analytical approach including X-ray fluorescence (XRF), diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and Raman spectroscopy. This approach allowed the identification of the pigments and the classification of the binding media. The results reveal a combined use of traditional Chinese and imported European materials. Several pigments like cinnabar, lead white, orpiment, carbon black and copper-arsenic green (probably emerald green) were found in both paintings; red lead, artificial ultramarine blue, Prussian blue and ochre appear in at least one of the paintings. The proof of limewash (calcite and small amounts of portlandite) as a backing layer in “Yingying and Hongniang” indicates that clamshell white was also used for reverse glass paintings. Drying oil was classified as a binding media in most areas of both paintings. However, the orange background of The Archer yielded prominent bands of both proteinaceous and fatty binder.

T1 - Innovation Network PerFluSan N2 - Per und polyfluorierte Alkylsubstanzen (PFAS) werden im Rahmen ihres breiten industriellen Einsatzes in die Umwelt ein­gebracht, wo sie aufgrund ihrer kritischen Eigen­schaften ein Problem darstellen. Der nach­haltige Schutz von Mensch und Umwelt vor dieser Stoff­gruppe ist eine wichtige Zukunfts­­aufgabe. Verfügbare PFAS-Reinigungs- und -Sanierungs­verfahren sind jedoch teuer und oftmals unzul­änglich. PerFluSan möchte einen entscheidenden Beitrag zur Lösung dieses Problems leisten, indem hier neue PFAS-Sanierungs­verfahren für Böden und Wässer, sowie innovative analytische Methoden zum PFAS-Nachweis entwickelt werden. Die lang­fristige Vision ist es, PerFluSan zu einer nationalen Anlauf­stelle der PFAS-Thematik auszubauen, die mit Hilfe der Synergien zwischen den PerFluSan-Akteuren alle Aspekte der Problematik ganz­heitlich, nachhaltig und effektiv adressiert. N2 - Per- and polyfluorinated alkyl substances (PFAS) are transferred into the environment as part of their broad industrial use, where they pose a problem due to their critical properties. The sustainable protection of people and the environment from this group of substances is an important task for the future. However, available PFAS removal and remediation processes are expensive and often inadequate. PerFluSan would like to make a relevant contribution to solve this problem by developing new PFAS remediation methods for soils and water, as well as innovative analytical methods for PFAS detection. The long-term vision is to develop PerFluSan into a national contact point for the PFAS topic, which uses synergies between the PerFluSan actors to address all aspects of the problem holistically, sustainably and effectively.

On the contrary, the WKI flask method was leading to more variable results depending on sample geometry. Thus, microchambers could be used for reliable routine market surveillance. An exposure assessment led to noticeable formaldehyde indoor air concentration values, pointing out the need for an effective Surveillance of such samples.

SOPs are available for the disciplines of physical-chemical characterisation, for toxicology, for environmental applications and for exposure applications. Furthermore the SOPs need to be integrated in the regulatory framework and need to be detailed enough for the digital processing. This is highlighted in this presentation.

Together with bacteria and algae they may establish subaerial biofilms and cause weathering of the surfaces they grow on. Their impressive survival abilities as well as their constitutive protective pigmentation and cluster-like microcolony organisation are similar in environmental isolates as well as in heat-tolerant opportunistic pathogens of animals and humans. We selected the rock-inhabiting fungus Knufia petricola (class Eurotiomycetes, order Chaetothyriales) that exhibits all the characteristics of microcolonial black fungi such as yeast-like cell growth, absence of reproductive structures and constitutive dihydroxynaphthalene (DHN) melanogenesis (Nai et al. 2013, Fungal Genet Biol). We developed protocols to efficiently generate and transform protoplasts resulting in stable homokaryotic transformants by targeting genes involved in pigment synthesis. The differences between the wild-type fungus and its melanin-deficient mutants were tested in geomicrobiological experiments and measured are now discussed in detail, with special accent on the possible effects of the mutation on EPS and other exuded substances.

A1 - Hahn, Oliver A1 - Golle, U. T1 - Blindness and Insight. The Rhetoric of Connoisseurship and the Investigation of Materiality. N2 - The aim of the lecture is to present the productive interplay of connoisseurs and material analysis using the example of selected drawings from the Rembrandt collection of the Klassik Stiftung Weimar. We try to determine the point at which the question of the materiality of the drawings makes sense in the traditional discourse of connoisseurship. On the one hand, this involves the question of authorship – Rembrandt – or not? – and the locating of attributed drawings in the context of the work. On the other hand, it is about making drawing processes visible, characterizing ways of drawing and workshop practices as well as distinguishing different forms of reworking and copying within the Rembrandt workshop. The material analyses culminate in the question of whether Rembrandt’s inks can be distinguished at all. It becomes apparent that the newly gained knowledge about the materiality of the drawing no longer reveals itself to the “mere” view of the connoisseur. Rather, it is only generated by the digital image. The rhetoric of connoisseurs must therefore be contrasted with the necessity of a hermeneutics of the digital image. The envisaged “material turn” of drawing science is thus simultaneously able to take up the critique of the question of authorship, which has been growing ever more recently, and to transfer it to a more comprehensive perspective of aesthetics of production.
