Electric Field Effect in Atomically Thin Carbon Films
K. S. Novoselov, A. K. Geim, et al.
Overview
Geim and Novoselov isolated graphene — a single atomic layer of carbon — and showed it is a stable, highly conductive two-dimensional crystal. Famously, they peeled it from graphite using adhesive tape.
Launched 2D materials science; won the 2010 Nobel Prize in Physics.
Key findings
Methods
Mechanical exfoliation ('the Scotch-tape method') of graphite onto an oxidised silicon wafer, optical identification of monolayers, and fabrication of field-effect devices to measure conductivity versus gate voltage.

Possible High-Tc Superconductivity in the Ba-La-Cu-O System
Bednorz and Müller discovered superconductivity in a copper-oxide ceramic at a far higher temperature than any known material, breaking the long-standing temperature ceiling and launching the field of high-temperature superconductivity.

C60: Buckminsterfullerene
The discovery of C60, a soccer-ball-shaped molecule of sixty carbon atoms. While vaporising graphite, the team found an unusually stable carbon cluster and proposed it was a hollow truncated-icosahedron cage, naming it after the architect Buckminster Fuller.

The Nature of the Chemical Bond
Pauling applied the new quantum mechanics to chemistry, explaining how atoms share electrons to form bonds. He introduced concepts — orbital hybridisation, resonance, and bond character — that became the language of structural chemistry.
