Theoretical framework for technology-mediated public engagement with science - Nature

MainThe Bardeen–Cooper–Schrieffer theory of superconductivity, where the electron–phonon interaction binds two electrons into a Cooper pair, forms the basis of our present understanding of conventional superconductors. The critical temperature Tc is governed by an electron–phonon coupling constant λph through the McMillan formula1. The same interaction is also known to scatter electrons in the normal (resistive) state. At intermediate temperatures, where the resistivity ρ(T) is T linear, the associated scattering rate 1/τ = 2πλtrT. Here λtr is a measure of the electron–phonon coupling strength as manifested in charge transport. A near equivalence of λph and λtr has been demonstrated for a wide array of elements and alloys2 (Supplementary Fig. 2), affirming the correlation between the pairing strength and the strength of the relevant (transport) scattering process. Many superconductors of current interest, including heavy fermions, Fe-based superconductors, organic conductors, nickelates and cuprates, are believed to have a pairing mechanism that is non-phononic in origin.

With the iPhone Duo launch imminent (and the device backordered until January), we're now getting concrete information from Apple regarding some specifications that were previously unconfirmed. Apple recently released an EU energy label for the company's first-ever foldable smartphone, and we now know just how big the iPhone Duo's battery is. The iPhone Duo will be equipped with a 4,883 mAh battery. This matches previous reports based on leaks that said the iPhone Duo would utilize two battery cells, one 2,962 mAh and one 1,921 mAh battery, which combined add up to 4,883 mAh. This means that the iPhone Duo will have a bigger battery than its closest foldable competitors, such as the Samsung Galaxy Z Fold 8 and Google Pixel 11 Pro Fold.
