Combining Density Fractionation and Ca K‐Edge XANES Reveals Contrasting SOM–Mineral Association Patterns Shaped by Parent Material in Forest Soil O Horizons

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Soil organic matter (SOM) accumulation in forest soils is strongly influenced by interactions with inorganic constituents derived from parent material mineralogy. However, their role in the forest floor remains underexplored.

Challenges in dating blanket peat and implications for understanding its initiation in Ireland

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Blanket peat is widespread in maritime extra‐tropical environments. Prehistoric land‐use activity was traditionally invoked as the stimulus of blanket peat initiation in the British Isles, but recently, climate has been viewed as the driver of peat formation.

Study of Garnets in Hellenistic–Roman Jewellery From the Collections of the Archaeological Museum of Thessaloniki, Greece

open access: yesJournal of Raman Spectroscopy, EarlyView.
This study presents the gemological analysis of 25 garnets from Hellenistic and Roman jewellery in the Archaeological Museum of Thessaloniki using mobile Raman spectroscopy and micro‐EDXRF. The garnets are classified into three geochemical clusters, with notable differences in distribution between Thessaloniki and Pydna, suggesting distinct trading ...

Vapor Deposition of Polymer Structures: From 2D Surface Coatings and Surface Microstructures to 3D Building Blocks and Structural Monoliths

open access: yesMacromolecular Rapid Communications, EarlyView.
This review discusses the progress of vapor‐deposited polymer structures, from simple thin films and surface microstructures to complex 3D architectures and monoliths. It covers fabrication methods, polymerization mechanisms, and processes for fabricating these structures. The applications of these polymers are discussed, focusing on device integration

Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Trace Element and Isotopic Characteristics of Plagioclase Megacrysts in Plagioclase Ultraphyric Basalts (PUB)

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Major, trace, and isotopic compositions of plagioclase megacrysts from plagioclase ultraphyric basalts (PUB) from multiple mid‐ocean ridges were determined to characterize the liquid compositions from which they were derived.

Study on the Cohesive Characteristic of Nano‐SiO2 Bioinspired Grafting Basalt Fiber and Asphalt

open access: yesNano Select, EarlyView.
Nano‐SiO2 bioinspired grafting basalt fiber (BF) was prepared by chemical grafting method based on the bioinspired idea of mussel‐plaque. The mechanism of nano‐SiO2 bioinspired grafting BF was analyzed by micro‐morphology, functional group changes, and elemental composition tests.

Volcanic soils alleviate the allelopathic capacity of Empetrum nigrum in degraded tundra ecosystems

open access: yesOikos, EarlyView.
Land degradation due to unsustainable land use is of major concern worldwide and recovery is often slow. A potential mechanism behind slow recovery of degraded ecosystems is the retarding impacts of allelopathic plant species on the establishment of species that might facilitate the recovery process.
