1959
Buehler NOL
William Buehler’s team at Naval Ordnance Lab named NiTiNOL.
Nitinol did not arrive as a finished commodity. NOL 1959 Buehler around United States still explains who makes it and which tests it sits in.
Ten dated points, five eras and three milestones below are the spine — not a complete industrial history.

1961Coffee-pot demo
Folded strip unkinks in hot water — the myth and the lab both persist.
1970sOrthodontic archwires
First large medical market.
1980sPipe couplings
Cryofit aero hydraulic couplings.
1990sSelf-expanding stents
Nitinol cages in vessels.
2000sASTM F2063
Wrought NiTi medical spec.
2010sAdditive NiTi
Porous implants, still tricky oxygen.
2010sActuator wires
Robotics and consumer gadgets of mixed reliability.
2020sFatigue standards
Million-cycle claims need waveform honesty.

Fibra de carbono
Filamentos de polímero com folhas tipo grafite: aero e bikes; o fogo é a resina.
Geral 49 ⬡Grafeno
Uma folha de carbono de um átomo: Nobel, hype em compósitos, poucos usos honestos.
Geral 50 ☁️Aerogel
Esponja de sílica nanométrica: λ entre os mais baixos; frágil sem manta.
Geral 60 ☀️Perovskita
Haletos ABX3 que dispararam a eficiência solar de laboratório; umidade, chumbo, vida.
