Crystallographic perspective on xenon reactivity with aluminium-containing minerals under extreme conditions

Objective

Xenon (Xe) is a noble gas that was thought to be inert up to the middle of the 20th century. Recently, it has attracted more attention due to its uses in dark-matter detectors, in propulsion for space exploration, and due to its effective anaesthetic and other therapeutic properties. For these applications, xenon is extracted from air, but it is scarce and costly. However, Xe could be retained under the Earth's surface, potentially providing another deep source of this gas that could facilitate further technological and medicinal advances.
Current data on xenon retention in minerals is sparse due to extreme reaction conditions, instability of products, and instrumental limitations. The CrystXeMin project, supported by Marie Skłodowska-Curie Actions programme, aims to systematically investigate reactivity of xenon with common minerals under Earth crust conditions while utilizing crystallographic knowledge to mitigate instrumental limitations. This study will not just expand knowledge on the reactivity of this inert gas and produce the first Xe-rich minerals recoverable at ambient conditions. The project will unveil natural minerals that can react with xenon and can be used to capture and recycle this gas. Furthermore, an understanding of Xe concentration mechanisms can lead to the location of deep sources of this gas, facilitating its use for technological advances.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

HORIZON-TMA-MSCA-PF-EF - HORIZON TMA MSCA Postdoctoral Fellowships - European Fellowships

Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
