Morphology and Photoelectrochemical Properties of Sputtered WO3:Mo Anodes

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
WO3:Mo thin films for photoelectrochemical water splitting were deposited by sputtering from a W:Mo target. Substrate temperature, pressure, oxygen partial pressure, deposition rate, and film thickness were systematically varied. The results show that the substrate temperature is the dominant parameter governing both the film morphology and the ...

A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

Archaeometry, EarlyView.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

Early Bronze Age Copper Circulation in the Guadalentín and Segura Valleys (SE Spain)

Archaeometry, EarlyView.
ABSTRACT Identifying the sources of copper used in Early Bronze Age metalwork from south‐east Spain is key to resolving a long‐running debate concerning centralized control, or lack thereof, over El Argar society's economic organisation. This study provides the first substantial integrated programme of EDXRF and MC‐ICP‐MS analyses for copper‐base ...

Tracing Identity in a Fragmented Past: Multi‐Proxy Analysis of Human Skeletal Remains From Dungowan Creek, New South Wales, Australia

Archaeometry, EarlyView.
ABSTRACT Human skeletal remains constitute critical archaeological evidence for reconstructing past societies, yet their investigation requires careful ethical, cultural, and legislative consideration. This paper reports on the discovery, recovery and analysis of a set of skeletal remains encountered during a cultural heritage management (CHM ...

Late Iron Age and Early Roman Brooches From the Lower Rhine Area: Provenance of the Metal Supply Traced Through Lead Isotopes

Archaeometry, EarlyView.
ABSTRACT Geochemical analysis of five brooch types from the Lower Rhine area dated to the last century bc and first century ad is used to constrain resource use, exchange and mobility. Lead isotope ratios demonstrate an Iberian provenance for copper in bronze Late Iron Age brooches.

Influence of Laser Repetition Rate, Fluence and Spot Size on LA‐Q‐ICP‐MS/MS 87Sr/86Sr Precision: Insights from Apatites and Silicate Glasses

Geostandards and Geoanalytical Research, EarlyView.
Key Points Higher laser repetition rate, fluence and larger spot size increase signal intensity. Higher laser repetition rate produces overlaps in aerosolised particles, improving signal stability and precision. For Sr‐rich materials, moderate spot diameter (≤ 60 μm), 3 J cm‐2 fluence and ≥ 12 Hz repetition rate are recommended.
