Transition of amorphous to crystalline oxide film in initial oxide overgrowth on liquid metals [PDF]
, 2011 It is important to understand the mechanism of oxidation in the initial stage on the free surface of liquid metals. Mittemeijer and co-workers recently developed a thermodynamic model to study the oxide overgrowth on a solid metal surface.

Vortices and quasiparticles near the "superconductor-insulator" transition in thin films [PDF]
, 2005 We study the low temperature behavior of an amorphous superconducting film driven normal by a perpendicular magnetic field (B). For this purpose we introduce a new two-fluid formulation consisting of fermionized field induced vortices and electrically ...

Frustrated flexibility in metal-organic frameworks
Nature Communications, 2021 Responsiveness in metal-organic frameworks involving amorphous phases remains poorly understood. Here, the authors demonstrate MOFs that reversibly switch between well-defined crystalline and structurally degenerate amorphous states mediated by competing
