[#TOP10] ☀️ « Passant de ~10GW à 600GW sur 10 ans. L’énergie solaire mondiale peut alimenter le Brésil. Cette utilisation dépassera nos réserves de silicium! »

➡️ Pour Nathanaëlle Schneider, il faut privilégier la piste de matériaux alternatifs.

"Urban mining" – the process of recovering valuable metal from electronic waste – could become much less energy-intensive thanks to a newly-expanded technique called flash Joule heating.

Conventional soft capacitive pressure sensors only work at pressures below 3 kPa, meaning that tight-fitting clothing can be enough to hinder their performance. @nanshulu and colleagues @UTAustin built a hybrid sensor that works over a much wider range. https://t.co/iNpFhMbrw1

A new ultrasound technique that measures the strength of atomic bonds within 2D materials, as well as the weaker forces between layers, reveals that the velocity of sound within these materials depends on the layers’ stacking arrangement. https://t.co/0U1nFpwCZ6

Quantum materials known as Mott insulators can “learn” to respond to external stimuli in a way that mimics animal behaviour, say researchers @RutgersU. The discovery could lead to new AI algorithms. https://t.co/DxpURPF3d9

“Where does the local magnetism come from in this metal-organic nanomaterial?” Nanoscience researcher @kumar_dhaneesh of @FLEETCentre found that it's all in the material's star-like "kagome" structure.

Electrons in a transition metal superconductor called ditetrelide (niobium germanide) flow like a fluid rather than behaving as individual particles – a finding connected to the physics of electron-phonon liquids. https://t.co/ZrRCmZi2ys
