Inverted Classroom question: Why does the energy vs. tempertaure curve in fig. 3 of the paper (HERE) tell us anything about the melting temperature?

  • Adhesion, Gecko effect, Lotos effect
  • Thomson model

Inverted Classroom reading: Gecko effect (link) and discussion on Spiderman's abilities and devices (link)

Inverted Classroom question: (1) Why does the gap between the 3p and 3s derived orbitals shrinks upon increasing the cluster size? (2) Why PES is useful to study this phenomenon? (3) Can we speak of a 3d band for all clusters under study?  Manuscript: Gantefoer et al., Chemical Physics Letters 1994:  Shell structure and s-p hybridization in small aluminium clusters.
