![Left: A beam of electrons generates vibrational waves in a crystal lattice that are then reflected by quantum dots. Right: Generated vibrations are more easily reflected by abrupt, sharp interfaces of materials than by diffuse ones.](/-/media/bes/mse/images/highlights/2024/Pan.png?h=544&w=936&la=en&hash=81D974DD9F233DF01E8D309EE95F0DC678891544B46662F7DB2526F988CF0EB3)
Unveiling How Heat Moves in Materials with Atomic-Scale Resolution
Scientists develop a nanoscale electron imaging method that reveals the dynamics of the collective vibrations of atoms at the interface between materials.

Quantum Effects Make Electrons Superconduct while Standing Still
Twisted bilayer graphene defies conventional theories by exhibiting superconductivity despite a vanishingly small charge carrier velocity.
