“…Similar to human remains,p archment [29,30] and leather [54] are rich in hydrogen and amenable to investigation by strayfield NMR. As tudy by Zhu et al investigating treated and untreated arctic skin clothing found that not only can the presence of treatments be determined from ad epth profile but even the type of treatment can be distinguished.…”

Nuclear magnetic resonance (NMR) provides in situ information about selected isotope densities in samples and objects, while also providing contrast through rotational and translational molecular dynamics. These parameters are probed not only in NMR spectroscopy and imaging but also in nondestructive materials testing by mobile stray-field NMR, the unique properties of which are valuable in cultural heritage studies. We present recent progress in the analysis of cultural heritage with mobile H NMR stray-field sensors, for which the detection zone is outside of the NMR magnet. Prominent applications include the analysis of stratigraphies in paintings and frescoes, and the assessment of material states changing under the impact of aging, conservation, and restoration.

“…Collagen materials have an intrinsic property of shrinking when subjected to heating in an aqueous medium, reducing their length to a quarter of the original. The temperature at which the shrinking begins, the one at which the fibers contract simultaneously and the one at which shrinking is completed are indicators on the basis of which the hydrothermal stability and structural heterogeneity of the collagen fibers [10][11][12][13] are evaluated.…”

This paper presents an overview of the conservation state of the tawed white leather, parchment and reused parchment bookbindings from the Rare Book Collection of the Romanian Academy Library. The transdisciplinary study was jointly conducted by the researchers of INCDTP-ICPI and Manuscripts and Rare Book Department of the Romanian Academy Library. Over 50 bindings in alum-tawed (white) leather, parchment and reused parchment were analyzed in situ using specific non-invasive or micro-invasive analysis methods such as visual and microscopic analyses, thermal microscopy (imageMHT method), attenuated total reflection (ATR), Fourier transform infrared spectroscopy (FTIR), and X-ray Fluorescence Spectrometry (XRF). Based on these results, conservation sheets have been drawn up including damage status, threats and conservation recommendations for each investigated bookbinding. Two conservation sheets are illustrated for alum-tawed and re-used parchment bindings. This is the first Romanian study dedicated both to the artistic and material aspects of rare book bindings so far. KEY WORDS: bookbinding, alum-tawed leather, parchment, damage status, conservation reccommendations LEGĂTURI DE CARTE RARĂ DIN COLECŢIILE BIBLIOTECII ACADEMIEI ROMÂNE -STUDIU MULTIDISCIPLINARREZUMAT. Această lucrare prezintă o imagine de ansamblu asupra stării de conservare a legturilor de carte din piele albă argăsită, pergament şi pergament reutilizat din Colecţia de Carte Rară a Bibliotecii Academiei Române. Studiul transdisciplinar a fost realizat în comun de către cercetătorii din cadrul INCDTP-ICPI şi din cadrul Departamentului de Manuscrise şi Cărţi Rare al Bibliotecii Academiei Române. Peste 50 de legături din piele argăsită cu alaun (albă), pergament şi pergament refolosit au fost analizate in-situ utilizând metode specifice de analiză neinvazivă sau microinvazivă, cum ar fi analize vizuale şi microscopice, microscopie termică (metoda imageMHT), reflexie totală atenuată (ATR), spectroscopie în infraroşu cu transformată Fourier (FTIR) şi spectrometrie de fluorescenţă de raze X (XRF). Pe baza acestor rezultate, au fost întocmite fişe de conservare, care includ starea de deteriorare, riscuri şi recomandări de conservare pentru fiecare legătură de carte studiată. Două fişe de conservare sunt ilustrate pentru legături din pergament argăsite cu alaun şi reutilizate. Acesta este primul studiu românesc de până acum dedicat atât aspectelor artistice, cât şi aspectelor materiale ale legăturilor de carte rară.

Die Kernspinresonanz ermöglicht In‐situ‐Bestimmungen der Isotopendichte in Proben und Objekten. Dabei erzeugen Relaxationsprozesse weiteren Kontrast, der nicht nur mit der NMR‐Spektroskopie oder der Magnetresonanztomographie, sondern auch über die der zerstörungsfreie Streufeldanalyse mit tragbaren 1H‐NMR‐Sensoren erfasst werden kann. Bei unilateralen NMR‐Sensoren liegt das Detektionsvolumen außerhalb des Gerätes, sodass mobile Sensoren mittlerweile auch für Untersuchungen von Kunst und Kulturgut genutzt werden. Die wichtigsten Anwendungen umfassen die Analyse von Schichtstrukturen in Gemälden und Fresken sowie die Verfolgung von alterungsinduzierten Veränderungen der Materialeigenschaften durch Alterung, Konservierungs‐ oder Restaurierungsmaßnahmen.
