Adsorption of rare earth elements in regolith-hosted clay deposits

open access: yesNature Communications, 2020
Global resources of heavy Rare Earth Elements (REE) are dominantly sourced from Chinese regolith-hosted ion-adsorption deposits in which the REE are inferred to be weakly adsorbed onto clay minerals.

Evaluating the Relationship Between the Area and Latitude of Large Igneous Provinces and Earth's Long‐Term Climate State

open access: yesGeophysical Monograph Series, Page 153-168., 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.

Additive manufacturing of lunar regolith structures

open access: yesOpen Ceramics, 2021
The key to any presence in space being sustainable is the ability to manufacture the necessary structures and spares in situ and on-demand, in order to avoid the cost, volume, and up-mass constraints that would prohibit a successful launch with ...

Gas-Driven Regolith-Sampling Strategy for Exploring Micro-Gravity Asteroids

open access: yesIEEE Access, 2020
Small celestial bodies contain abundant scientific information to understand the origin and evolution of the solar system. The acquisition and analysis of regolith sample is the most direct and effective way to explore the geological construction of ...

Farming on Mars: Treatment of basaltic regolith soil and briny water simulants sustains plant growth

open access: yesPLoS ONE, 2022
A fundamental challenge in human missions to Mars is producing consumable foods efficiently with the in situ resources such as soil, water, nutrients and solar radiation available on Mars.

A proposal of lunar long duration method (Fabrication of lunar environment simulator and experimental validation)

open access: yesNihon Kikai Gakkai ronbunshu, 2014
A lunar long duration method which utilizes a characteristic of a very low thermal conductivity of lunar regolith has been proposed. The principle of this method is to put heater in desired depth of the regolith and heat up the regolith layer during ...

The importance of Phobos simulants: a review on our current knowledge

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Phobos, a satellite of Mars, was successfully studied by flyby, orbiter, and landing missions to the Red Planet, but several questions remain about its origin, composition, and relationship to Mars.

The collisional evolution of undifferentiated asteroids and the formation of chondritic meteoroids [PDF]

open access: yes, 2016
Most meteorites are fragments from recent collisions experienced in the asteroid belt. In such a hyper-velocity collision, the smaller collision partner is destroyed, whereas a crater on the asteroid is formed or it is entirely disrupted, too.

A multidisciplinary study of an exceptional prehistoric waste dump in the mountainous inland of Calabria (Italy) : implications for reconstructions of prehistoric land use and vegetation in Southern Italy [PDF]

open access: yes, 2020
The mountainous inland of northern Calabria (Southern Italy) is known for its sparse prehistoric human occupation. Nevertheless, a thorough multidisciplinary approach of field walking, geophysical survey and invasive research led to the discovery of a ...

Bedrock geochemistry influences vegetation growth by regulating the regolith water holding capacity

open access: yesNature Communications, 2020
Although low vegetation productivity has been observed in karst regions, whether and how bedrock geochemistry contributes to the low karstic vegetation productivity remain unclear.
