The photophysical properties of Ru(II) and Re(I) polypyridyl complexes including a bis-bipyridyl pyrene ligand are presented. ([(bpy)(2)Ru](2)bpb)(4+) [(CO)(3)ReCl(bpb)] (bpy = 2,2'-bipyridine, bpb 1,6-bis-(4-(2,2'-bipyrid-yl)-pyrene) were designed with the intent examining intramolecular energy migration between MLCT states localized on metal pyrene-localized (3)(pi-pi) states. Absorption spectroscopy both containing reveals that in addition to pyrene-centered (1)(pi-pi) transitions, new...

Architecture represents key evidence of dynastic practice and change in the archaeological world. Chronologies for many important buildings sequences, including iconic temples medieval Angkor Cambodia, are based solely on indirect associations from inscriptions architectural styles. The Baphuon temple, one last major without textual or scientifically-derived chronological evidence, is crucial both context date its construction period when western façade was modified into a unique, gigantic...

The high-grade mineral ores of the Phnom Dek region in central Cambodia have long been suspected playing a major role rise Angkor, largest medieval polity mainland Southeast Asia. This article presents first comprehensive study by Industries Angkor Project (INDAP) to document extent industrial activity this and test important relationship. Using combination intensive field survey, surface collection, archaeometallurgical analysis, we evaluate temporal spatial patterning iron production...

A rescue excavation has unearthed the remains of a bridge crossing Moselle River at Dieulouard (Meurthe-et-Moselle, France). This constitutes one rare examples non-religious monumental architecture from Carolingian period in France. The present archaeometrical study, conducted on set architectural iron fastenings, provides an opportunity to examine modalities through which early medieval building yards acquired ferrous materials. Located within vicinity active ironmaking zones, hypothesis...

In the early days of iron metallurgy in Western Europe, most widespread type ‘trade iron’ (semi‐product) was bipyramidal shape. Although they are frequently found, little is known about how were manufactured and circulated, or even their age. An interdisciplinary approach applied to Durrenentzen deposit (Haut‐Rhin, France), third‐largest Europe terms artefact quantities, an attempt reconstruct technological, social economic context that caused them be abandoned. A morphometric study 51 bars...

Extensive spatial and temporal distribution of high-quality data are essential for understanding regional global behaviors the geomagnetic field. We carried out chronological archaeomagnetic studies at Angkor-era iron-smelting site Tonle Bak in Cambodia Southeast Asia, an area with no available to date. recovered high-fidelity full-vector information from 11th 14th century this region, which fill gaps will significantly improve models. These results reveal a sharp directional change field...

Abstract The large number of iron-laden wrecked ships discovered off Saintes-Maries-de-la-Mer (south France) since the 1990s has enriched our knowledge both maritime trade in Mediterranean and ferrous bars used during antiquity. This exceptional corpus spawned numerous studies fields archaeology, history, archaeometallurgy, but, despite a relatively well-documented context, chronology wrecks is still to be clarified. Until recently, was mainly supported by archaeological remains found cargo...
