Investigation of Organic Materials From the ‘Royal’ Burials of Xiongnu (Noin‐Ula, Mongolia) by Srxrf and XAFS Methods

The burials of famous Xiongnu people are a unique source of information about Xiongnu culture, due to the variety of organic findings. SRXRF analysis of hair, clay, bones, teeth and woollen cloth was carried out. An anomalously high copper content was observed in all hair samples, whereas the levels of copper in bone and clay were low. To define the hair morphology and the elemental distribution in the hair cross‐section, high‐resolution X‐ray computed tomography (HRXCT) and energy‐dispersive spectroscopy (EDS) with scanning electron microscopy (SEM) were used. The X‐ray absorption fine‐structure method (XAFS) was applied to determine the local copper environment. The majority of the copper species in the hair and enamel samples are present as Cu2+ cations in a distorted octahedral (4 + 2) coordination, surrounded by light ligands (oxygen/nitrogen). A similar distorted octahedral coordination is typical for both inorganic mixed oxide/hydroxide Cu nanosystems and metal–organic Cu complexes (with oxygen/nitrogen).

Archaeological human hair in a burial context: Microscopical evaluation of samples from Iași, Romania (18th–19th centuries)

Owing to its resistance to degradation, hair is an important bio‐sample with unique properties used to study post mortem decompositional changes. The present paper is a microscopical approach to preserved human scalp hair discovered at the 18th–19th‐century archaeological site of Iași, Romania. The hair fibre alterations were assessed using optical microscopy, scanning electron microscopy, image analysis and hair histological scores. External alterations showed a statistically significant heterogeneous degradation. Image analysis results of the internal degradation of hairs were correlated to external lesions. The results consider the implication of intrinsic biological factors in the post mortem degradation of human hair preserved in graves with comparable environmental conditions.

Die Nachahmung von spezifischen (z. B. mechanischen, optischen und strukturellen) Eigenschaften, die in alten und historischen Systemen beobachtet werden, wird in diesem Kurzaufsatz als Paläo‐Inspiration bezeichnet. Zum Beispiel kann die Bergung in der Archäologie oder Paläontologie zur Identifikation von Materialien dienen, die a posteriori sehr widerstandsfähig gegen Veränderungen sind. Umso ermutigender ist die Tatsache, dass viele historische Materialien mit sanften chemischen Methoden hergestellt wurden, wobei oft nur geringe Energieressourcen und manchmal primitive Fertigungsmittel zur Verfügung standen. In diesem Kurzaufsatz werden historische Systeme als Inspirationsquelle für innovatives Materialdesign im Anthropozän betrachtet.
