Experimental Analysis for Tritium Recovery in Lithium–Lead Alloy Using a Membrane Gas–Liquid Contactor Concept

The eutectic PbLi (15.7 at.% Li) alloy appears promising for producing tritium from fertile materials. Currently, in nuclear fusion design, the technologies being explored for tritium extraction in molten phases primarily focus on (i) established processes based on Gas–Liquid Contactor (GLC), such as bubble, packed, or spray columns, or on (ii) exploiting hydrogen permeation phenomena using dense metallic membranes, i.e., Permeation Against Vacuum (PAV). This work introduces a new concept, a ...

A New Master Supernovae Ia sample and the investigation of the Hubble tension

Modern cosmological research still thoroughly debates the discrepancy between local probes and the Cosmic Microwave Background observations in the Hubble constant (H0) measurements, ranging from 4 to 6σ. In the current study, we examine this tension using the Supernovae Ia (SNe Ia) data from the Pantheon, Pantheon+ (P+), Joint Lightcurve Analysis (JLA), and Dark Energy Survey, (DES) catalogs combined together into the so-called Master Sample. The sample contains 3714 SNe Ia, and is divided al...

Selection and characterization of bacterial consortia for the degradation of space organic waste

Planned human exploration beyond low Earth orbit involves establishing long-term Moon and Mars settlements. Due to the impracticality of continuous resupply from Earth for such missions, it is crucial to develop systems that allow partial or complete in situ recycling of resources necessary for human survival, such as Bioregenerative Life Support Systems (BLSSs), closed artificial ecosystems providing oxygen, food, and water. Microorganisms can play an important role in BLSSs for space missio...

Estimating the air quality standard exceedance areas and the spatial representativeness of urban air quality stations applying microscale modelling

This study builds upon the findings of a FAIRMODE intercomparison exercise conducted in a district of Antwerp, Belgium, where a comprehensive dataset of air pollutant measurements (air quality stations and passive samplers) was available. Long-term average NO2 concentrations at very high spatial resolution were estimated by several dispersion modelling systems (Martín et al., 2024) to investigate the ability of these to capture the detailed spatial distribution of NO2 concentrations at the mi...

An analytical framework for computing AC losses in the HTS insert of the EU-DEMO central solenoid

High-temperature superconductors (HTS) are being explored for integration into coil systems for magnetic confinement fusion, due to their ability to extend operational margins in terms of temperature, current, and magnetic field. Recently, a conductor design based on a sector-assembled (SECAS) cable-in-conduit-conductor (CICC) concept was proposed for the innermost layer of the central solenoid (CS) module in the EU-DEMO tokamak. The dynamic nature of plasma scenarios, characterized by rapid ...
