@MonniauxD@social.sciences.re @limitesnumeriques@mastodon.design c'est bien ça. L'or nécessite moins de purification, mais des efforts extractifs plus grand. Le silicium est plus plus facile à extraire mais demande extrêmement plus de purification.
En plus de l'article "Purer than pure" https://arxiv.org/abs/2509.18768 @gauthier@mastodon.design a aussi réalisé deux diagrammes sur les procédés de purification/production :

I missed two presentations in the morning 😢 so no reports.

After a long lunch break (even by french standards), we are back in thematic discussion sessions.

We have 3 themes this afternoon :

• Visualizations
• XR
• Sustainability

In the sustainability session we looked at videos and discussed the following papers:

• Designing a Card-Based Design Tool to Bridge Academic Research & Design Practice For Societal Resilience https://dl.acm.org/doi/10.1145/3613904.3642686
• The Future of HCI-Policy Collaboration https://dl.acm.org/doi/10.1145/3613904.3642771
• Post-growth Human–Computer Interaction https://dl.acm.org/doi/10.1145/3624981

We didn't manage to discuss the following papers :

• From Exploration to End of Life: Unpacking Sustainability in Physicalization Practices
• SolarClub: Supporting Renewable Energy Communities through an Interactive Coordination System
• From Surplus and Scarcity towards Abundance: Understanding the Use of ICT in Food Resource Sharing Practices
