SR offers, in contrast to conventional X-ray sources, highly brilliant polychromatic, polarized radiation with which micro-domain X-ray fluorescence spectrometry becomes possible. A feasibility study of utility, conducted at BESSY (Berlin) and at DELTA (Dortmund), both synchrotron facilities of the third generation, to evaluate the use of wavelength dispersive X-ray fluorescence spectrometry in combination with synchrotron radiation is presented. First results for material analysis, obtained by combining the synchrotron radiation and a commercially available spectrometer commonly attached to a scanning electron microscope, are presented. The spectrometer, of the linear type, uses curved focusing Bragg-crystals of the Johann type which leads to a high spectral resolution up to 3 eV. Examples of micro-domain analyses are presented and compared with those obtained by synchrotron radiation induced energy dispersive X-ray fluorescence.

T1 - Revealing Silver Nanoparticle Uptake by Macrophages Using SR-μXRF and LA-ICP-MS N2 - To better study the impact of nanoparticles on both in vitro and in vivo models, tissue distribution and cellular doses need to be described more closely. Here silver nanoparticles were visualized in alveolar macrophages by means of synchrotron radiation micro X-ray fluorescence spectroscopy (SR-μXRF) with high spatial resolution of 3 × 3 μm2. For the spatial allocation of silver signals to cells and tissue structures, additional elemental labeling was carried out by staining with eosin, which binds to protein and can be detected as bromine signal with SR-μXRF. The method was compatible with immunostaining of macrophage antigens. We found that the silver distribution obtained with SR-μXRF was largely congruent with distribution maps from a subsequent laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) of the same tissue sites. The study shows a predominant, though not exclusive uptake of silver into alveolar macrophages in the rat lung, which can be modeled by a similar uptake in cultured alveolar macrophages. Advantages and limitations of the different strategies for measuring nanoparticle uptake at the single cell level are discussed.

T1 - Gold provenance studies for Romanian archaeological objects using micro-SR-XRF N2 - Studies by Synchrotron Radiation-X-Ray Fluorescence (SR-XRF) for the search of the presence of trace elements like Sb, Sn, Te and Pb in archaeological metallic objects found on the territory of Romania-old coins and Bronze Age jewelry, aimed to determine the provenance of the gold used in their manufacture. The results are compared with the detailed elemental composition of alluvial or primary gold samples, obtained by the same technique. This work attempted to establish the origin of the gold used for the mint of two different types of koson coins. We found that the kosons with monogram are made of refined gold, while the one used for the kosons without monogram is mainly alluvial. The gold used in the manufacture of the Calarasi Vulchitrun-type disk and the Tauteu hair ring is also of alluvial origin.

A1 - Radtke, Martin A1 - Reinholz, Uwe T1 - A study on gold and copper provenance for Romanian prehistoric objects using micro-SR XRF N2 - This study intends to clarify the metal provenance of gold archaeological items using the variation of the Au–Ag ratio and the presence of trace elements as Sn, Sb, Te, and Pb, concentrating on gold Dacian Koson coins, recovered recently. It also extends the area of our investigations to the copper provenance of Bronze Age artifacts—axes, sickles, and celts—found on Romanian territory. The experiments were performed by micro-SR XRF at BESSY Berlin, at the BAM-line facility. Two types of coins (Koson, with and without monogram) were analysed. The conclusions we reached were that most of the monogram coins are made from refined gold (3–5% Ag, less than 0.5% Cu), while the without monogram coins are made from native Transylvanian gold (9–20% Ag, 0.5–2% Cu), of alluvial origin, proved by the presence of Sn, Sb and Te embedded in the gold. The problem of provenance for prehistoric Romanian copper and bronze objects consists in linking their elemental compositional patterns to the ones of the Bronze Age regional mines from Bulgaria, Serbia or Transylvania, most likely used as ore sources for their manufacture. The studied samples present relevant traces of As, Ag, Sb, and Co, suggesting the most probable use of copper from Serbia or northern Bulgaria for their manufacture.

T1 - The charge of solid-liquid interfaces measured by X-ray standing waves and streaming current N2 - Measurements of ion distributions at a charged solid–liquid interface using X-ray standing waves (XSW) are presented. High energy synchrotron radiation (17.48 keV) is used to produce an XSW pattern inside a thin water film on a silicon wafer. The liquid phase is an aqueous solution containing Br and Rb ions. The surface charge is adjusted by titration. Measurements are performed over a pH range from 2.2–9, using the native Si oxide layer and functional (amine) groups as surface charge. The Debye length, indicating the extension of the diffuse layer, could be measured with values varying between 1–4 nm. For functionalized wafers, the pH dependent change from attraction to repulsion of an ion species could be detected, indicating the isoelectric point. In combination with the measurement of the streaming current, the surface charge of the sample could be quantified.

T1 - Studies on archaeological gold items found in Romanian territory using X-ray-based analytical spectrometry N2 - This paper is an overview of the work developed by our group in the investigations of museum objects and alluvial gold, reflected in a series of studies published between 2000–2011, supplemented with new results, unpublished up-to-date. The X-ray based spectrometric techniques employed range from various X-Ray Fluorescence (XRF) investigations to ion beam analysis, including synchrotron radiation XRF and micro-Particle Induced X-ray Emission. The gold objects discussed are mainly part of the Sarmizegetusa Dacian hoards—spiraled bracelets (armbands) and coins. After obtaining in 2011 the permission of the Romanian authorities to take very small (1–2 mg) samples from the most 'unimportant' areas of the Dacian bracelets and several Koson staters, to analyze them by micro-SR-XRF at BESSY, in February 2012, the investigation of several micro-areas of 17 stater and 28 bracelet samples revealed important micro-structural inhomogeneity, especially in Sn and Cu. The same inhomogeneous micro-structure has been seen in Transylvanian alluvial gold. The analyses revealed details on the fingerprint of geological gold deposits and also the main characteristics of ancient gold metallurgy procedures used by the Dacians: a relatively low temperature (lower than Au melting point) and hammering during heating to obtain an ingot through sintering. The use of the sintering procedure was proved for the spiraled bracelets and the Koson without monogram coins, a tradition starting in the Bronze Age in Transylvanian gold processing. The existence of micro-inclusions of Ta-minerals in alluvial gold was also detected, explaining Ta trace presence in the artifacts from the Pietroasa hoard.

Die meisten Objekte sind Blecharbeiten, die aus einer Vielzahl von Einzelteilen mit metallischem Goldlot zusammengefügt und mit Granulation oder granulations-imitierendem Perl- oder Kerbdraht verziert wurden. Nur vier kleine Ohrringe sind massiv gegossen. Zwei Zierbleche dürften über Patrizen (Positivmodeln), die Deckel der Astragale in Matrizen (Negativmodeln) geformt worden sein. Alle Objekte wurden mit Synchrotron- und atmosphärischer Röntgenfluoreszenz analysiert. Die Daten zeigen das breite Spektrum an Goldlegierungen, die im 7./6. Jahrhundert v. Chr. in Kleinasien verarbeitet wurden: vom natürlichen Seifengold (Elektrum) bis zu geläutertem, fast reinem Gold. Eine Korrelation zwischen Goldqualität und Verarbeitungsmethode konnte nicht festgestellt werden. Sowohl hochreines als auch mit viel Silber und Kupfer legiertes Gold wurde zum Schmieden von Blecharbeiten, aber auch zum Massivguss verwendet. Aus der Goldfarbe kann wegen des Phänomens der oberflächlichen Goldanreicherung nicht auf eine Legierungszusammensetzung geschlossen werden. Der 1963 angekaufte Fundkomplex aus lydischen Metallarbeiten und ostionischen Salbgefäßen aus Ton dürfte einen Grabfund des frühen 6. Jahrhunderts v. Chr. darstellen, dessen Herkunft aus Ephesos jedoch nicht zu sichern ist. KW - Gold KW - Synchrotron KW - XRF PY - 2017 SN - 1866-7007 VL - 9 SP - 57 EP - 83 PB - RGZM.

Several minute fragments of natural Carpathian gold-placer and primary-and some very small (a few milligrams) fragments of archaeological items were studied using micro Synchrotron Radiation X-Ray Fluorescence (micro SR-XRF) at the BESSY Synchrotron Facility in Berlin, Germany. The goal of the study was to identify the trace elements characterizing Carpathian gold, looking especially at Sn, Sb, Pb and Te, and to determine if the gold in the archaeological items is native or refined. Applications to the authentication and provenance of nine Dacian gold bracelets, koson coins and two Bronze Age items are presented.
