The ETNA mission concept: Assessing the habitability of an active ocean world

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Enceladus is an icy world with potentially habitable conditions, as suggested by the coincident presence of a subsurface ocean, an active energy source due to water-rock interactions, and the basic chemical ingredients necessary for terrestrial life ...

Climate variations on Earth-like circumbinary planets

open access: yesNature Communications, 2017
Large variations in insolation experienced by circumbinary planets raise the question of the habitability of such planets. Here, the authors show that while the changing insolation does not radically affect habitability, it does impact on the planet’s ...

Transition to a Moist Greenhouse with CO2 and solar forcing

open access: yesNature Communications, 2016
Greenhouse-gas forcing has previously been thought to be rather ineffective at destroying the habitability of Earth-like planets. Here, the authors show that CO2is as effective as solar forcing at causing a climate transition to a Moist-Greenhouse regime

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Mantle Flow and Anisotropy in Subduction Zones: Modeling and Clustering of Olivine Textures

open access: yesGeochemistry, Geophysics, Geosystems
The mantle near Earth's subduction zones endures intense deformation that generates anisotropic rock textures. These textures can be observed seismically and modeled geodynamically, but the complexity of this deformation makes analyses of these textures ...

User-friendly carbon-cycle modelling and aspects of Phanerozoic climate change

open access: yesApplied Computing and Geosciences
Carbon-cycle modelling is essential for testing the main carbon sources and sinks as climate forcings, and we introduce and describe GEOCARB_NET, a graphical user interface for the geologic carbon and sulfur cycle model GEOCARBSULFvolc.

Fluorine-Rich Planetary Environments as Possible Habitats for Life

open access: yesLife, 2014
In polar aprotic organic solvents, fluorine might be an element of choice for life that uses selected fluorinated building blocks as monomers of choice for self-assembling of its catalytic polymers.

Stress‐Induced Melting Controlled Failure Mechanisms of Methane Hydrate

open access: yesAdvanced Science, EarlyView.
We study methane hydrate via nanoindentation and nuclear magnetic resonance (NMR), finding its regional melting and mechanical properties, challenging existing views on hydrogen‐bonded crystals. Abstract Methane hydrate, a kind of nonstoichiometric crystalline, attracted worldwide attentions as a promising substitute energy. Its Dissociation is thought

A Novel Metric for Assessing Climatological Surface Habitability

open access: yesThe Planetary Science Journal
Planetary surface habitability has so far been considered, in the main, on a global scale. The increasing number of 3D modelling studies of (exo)planetary climate has highlighted the need for a more nuanced understanding of surface habitability.
