Insights into Red Deer Ecology during the Late Epigravettian: New isotopic evidence from Riparo Tagliente (Italian Prealps)

Journal of Quaternary Science, EarlyView.
Abstract The transition from the Last Glacial Maximum to the Late Glacial marked a shift from the cold conditions of Greenland Stadial‐2 (GS‐2) to the warmer phases of Greenland Interstadial‐1 (GI‐1), enabling the reoccupation of Alpine regions by Late Palaeolithic hunter‐gatherers.

Raman Line Scan Analyses and a New Hypothesis for the Formation of Anatase‐Hosting Microbialites: Study of the Stromatolites From Saint‐Jean‐de‐la‐Rivière, Cotentin, France

Journal of Raman Spectroscopy, EarlyView.
Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms. ABSTRACT Raman

Goethite Hinders Azo Dye Bioreduction by Blocking Terminal Reductive Sites on the Outer Membrane of Shewanella decolorationis S12

Frontiers in Microbiology, 2019
Iron (hydr)oxides are the most ubiquitous Fe(III)-containing minerals in the near-surface environments and can regulate organic pollutant biotransformation by participating in bacterial extracellular electron transfer under anaerobic conditions ...

Electrochemical Monitoring of Steel Corrosion in NS4 Solution Under Cathodic Protection Environment: Insights of Electrochemical Impedance Spectroscopy

Materials and Corrosion, EarlyView.
Electrochemical impedance spectroscopy (EIS) monitored corrosion on mild steel under cathodic protection in soil‐like conditions. CP reduced corrosion from 410 to 7 µm/yr, shifting the mechanism from mixed activation–diffusion to activation‐controlled, enabling protective calcareous and oxide film formation.

Fire Promotes Arsenic Mobilization and Rapid Arsenic(III) Formation in Soil via Thermal Alteration of Arsenic-Bearing Iron Oxides

Frontiers in Earth Science, 2019
Arsenic in oxic surface soils readily associates with Fe(III) oxide minerals such as ferrihydrite and goethite, predominantly as As(V). Fires are a common feature in many landscapes, creating high-temperature soil conditions which drive thermal ...

Selective leaching of nickel from prereduced limonitic laterite under moderate HPAL conditions- part I: Dissolution [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy, 2016
High pressure acid leaching (HPAL) is the primary method for extraction of nickel from limonitic laterite. The severe operating conditions, the complexity of facilities, and several technical problems, such as scale formation, have always ...

Ancient Chromophores and Auxiliaries: Phrygian Colorants from Tumulus MM at Gordion, Turkey, ca 740 BCE

Heritage, 2023
This paper discusses colorants found in Tumulus MM, the tomb of King Midas or his father, at Gordion, the capital of the Phrygian kingdom. Chromophores, colorants, and auxiliaries are preserved largely independent of the textiles they once colored.

Application of Electrical Resistance Probes for Corrosion Monitoring and Cathodic Protection Assessment of Offshore Structures

Materials and Corrosion, EarlyView.
A novel thick‐track electrical resistance probe with five sensing tracks was developed for offshore corrosion monitoring. The probe provides reliable, real‐time corrosion‐rate measurements in natural seawater. Corrosion‐rate trends showed strong agreement with weight‐loss coupon measurements.

Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

Allergy, EarlyView.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing
