Crustal thickness and lithospheric properties of Mercury constrained by gravity data

open access: yesGeo-spatial Information Science
The crust and lithosphere of Mercury record the footprints of exogenous and endogenous activities since its formation, and their physical properties provide important clues for understanding the overall evolution of Mercury.

Integrating Sustainability Into Dental Education: Students' Knowledge, Behaviours, and Curriculum Perspectives

open access: yesEuropean Journal of Dental Education, EarlyView.
ABSTRACT Introduction The healthcare sector contributes approximately 5% of global greenhouse gas emissions, and dentistry represents a notable environmental burden due to high energy consumption, material use, and medical waste generation. This study aimed to evaluate dental students' awareness, attitudes, and perceptions regarding environmental ...

Monitoring of gaseous elemental mercury in central Antarctica at Dome Concordia

open access: yesE3S Web of Conferences, 2013
Within the framework of the Global Mercury Observation System (GMOS), we are monitoring gaseous elemental mercury (Hg(0)) at the Dome Concordia Station to improve our understanding of atmospheric Hg in the Antarctic atmosphere.

(Ultra)high‐Pressure Metamorphism in Sedimentary Versus Basaltic Rocks: Insights From a Variscan Mélange in the South Carpathians

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT Reconstructing the pressure–temperature–time (P–T–t) evolution of (ultra)high‐pressure rocks is essential for constraining subduction and collisional dynamics. Subduction zones are often investigated using basic eclogites, whereas nonbasic high‐pressure rocks remain comparatively understudied, potentially hindering a comprehensive ...

Short‐term observations of double‐peaked Na emission from Mercury's exosphere

open access: yesGeophysical Research Letters, 2017
We report the analysis of short‐term ground‐based observations of the exospheric Na emission (D1 and D2 lines) from Mercury, which was characterized by two high‐latitude peaks confined near the magnetospheric cusp footprints. During a series of scheduled

On the Gravitational Energy of Planet Mercury

open access: yes, 2022
The Sun is travelling around the Solar System barycentre so that on average, orbiting Mercury is attracted to a position between the Sun's centre and the barycentre. This toroidal-Sun-effect generates a small quadrupole moment in the gravitational energy of Mercury, which cannot be reduced to zero by using heliocentric coordinates.

Revisiting the life cycle of Margalefidinium polykrikoides Group III

open access: yesJournal of Phycology, EarlyView.
Abstract Dinoflagellates produce cysts as a strategy to withstand environmental stressors, with nutrient depletion generally considered a key trigger for cyst production. Resting cysts are thick‐walled, typically composed of one to several layers, and characterized by a prolonged dormancy period.

Advanced aqueous alteration in primitive meteorites: Micro‐ to nanoscale studies of CR1 iron sulfides

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract This study documents micro‐ to nanoscale observations of primary nebular and secondary parent body iron sulfides in the CR1 GRO 95577. Despite the extensive alteration of the bulk sample, some primary sulfides managed to avoid alteration, having originally formed in the solar nebula during chondrule formation by either fission‐sulfidization or

Evaluating maturity of organic matter in hydrated C1 and CM‐like clasts and a dehydrated clast within a polymict eucrite and a howardite

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Volatile‐rich xenolithic clasts in different types of brecciated meteorites represent unique pristine solar system material. This study investigates the maturity and thermal history of organic matter using Raman spectroscopy and aqueous alteration effects using infrared spectroscopy in the matrix of 15 volatile‐rich clasts (C1 and CM‐like ...
