A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

X-Ray Spectrometry, EarlyView.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

The Fiery Eyes of a Maenad: Origin Determination of Faceted Garnet Eye Inlays in a Roman Bronze Bust From Southern Tyrol

Archaeometry, EarlyView.
ABSTRACT In 1837, the Tyrolean State Museum Ferdinandeum in Innsbruck, Austria, purchased a Roman bronze statue of a maenad from the 2nd century ce with red garnets as facetted eye inlays found near Brixen, Southern Tyrol. These garnets were investigated using optical microscopy, a portable hand‐held and a stationary micro‐X‐ray fluorescence device, as

Elemental depth profiling of thin film chalcogenides using MeV ion beam analysis [PDF]

, 2009
The comprehensive characterisation is one of many technical challenges in the fabrication of photovoltaic devices from novel materials. We show how the application of recent advances in MeV ion beam analysis, providing the selfconsistent treatment of ...

The Material Basis of 18th‐Century Meissen Porcelain

Archaeometry, EarlyView.
ABSTRACT In the summer of 1708, the quest for making hard‐paste porcelain from Saxonian clay and other mineral resources succeeded. This was achieved by applying as its essential ingredient newly discovered pure kaolin from Heidelsberg near Aue, western Saxon Ore Mountains.

Etiology, pathogenesis and treatment of peri‐implantitis: A European perspective

Periodontology 2000, EarlyView.
Abstract Peri‐implantitis is a plaque‐associated pathological condition occurring in tissues around dental implants. It is characterized by inflammation in the peri‐implant mucosa and progressive loss of supporting bone. Over the last 30 years, peri‐implantitis has become a major disease burden in dentistry.

Ultrafast Structural Dynamics of BlsA, a Photoreceptor from the Pathogenic Bacterium Acinetobacter baumannii [PDF]

, 2014
Acinetobacter baumannii is an important human pathogen that can form biofilms and persist under harsh environmental conditions. Biofilm formation and virulence are modulated by blue light, which is thought to be regulated by a BLUF protein, BlsA.

Research Trends on Trace Element Contamination in Brazilian Urban Lentic Ecosystems: Environmental and Policy Drivers

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Lentic ecosystems are vulnerable to contamination by trace elements, which can accumulate and pose risks to aquatic life and human health. In a large, developing country such as Brazil, marked by vast geographic, environmental, and socioeconomic diversity, it is crucial to understand how these factors shape research on this group of ...
