Investigating Technological Changes in Copper-Based Metals Using Portable XRF Analysis. A Case Study in Sicily

Open Archaeology, 2017
The introduction of copper-based metals in Sicily appears to have been a particularly late and slow process. A program of pXRF analyses on early metals in Sicily has revealed the use of mostly copper, and a very late introduction of tin.

Decoding the Structure of Benzodithiophene Polymers for High‐Efficiency Organic Solar Cells

Advanced Functional Materials, EarlyView.
This study reveals a unique solid mesophase in top‐performing benzodithiophene‐based polymers for solar cells, comprising stacked solid‐like and liquid‐like layers. Combining nanoscale fibrillar domains with amorphous regions, it introduces a new structural paradigm.

Early integration of pastoralism and millet cultivation in Bronze Age Eurasia

Proceedings of the Royal Society B, 2019
Mobile pastoralists are thought to have facilitated the first trans-Eurasian dispersals of domesticated plants during the Early Bronze Age (ca 2500–2300 BC).

A Mesolithic settlement site at Howick, Northumberland: a preliminary report [PDF]

, 2003
Excavations at a coastal site at Howick during 2000 and 2002 have revealed evidence for a substantial Mesolithic settlement and a Bronze Age cist cemetery. Twenty one radiocarbon determinations of the earlier eighth millennium BP (Cal.) indicate that the

Population history from the Neolithic to present on the Mediterranean island of Sardinia: an ancient DNA perspective

, 2019
Recent ancient DNA studies of western Eurasia have revealed a dynamic history of admixture, with evidence for major migrations during the Neolithic and Bronze Age. The population of the Mediterranean island of Sardinia has been notable in these studies –}

Further work at Kilise Tepe, 2007-11: refining the Bronze to Iron Age transition [PDF]

, 2014
The excavations at Kilise Tepe in the 1990s inevitably left a range of research questions unanswered, and our second spell of work at the site from 2007 to 2011 sought to address some of these, relating to the later second and early first millennia. This

Covalent Adaptable Networks with Associative Siloxane Exchange Enabled by Amide‐Based Internal Catalysis: Designing for Reprocessability and Extrudability by Increasing the Cross‐Link Density

Advanced Functional Materials, EarlyView.
Internally catalyzed siloxane dynamic chemistry is demonstrated resulting from amides covalently linked through alkyl chains to siloxanes. The alkyl length in the siloxane‐containing monomer tunes the network cross‐link density. Siloxane exchange dynamics are faster with increasing cross‐link density, because associative exchange is second order in ...
