Field studying materials' structure, properties, and performance across metals, ceramics, polymers, and thin films for electronics and energy uses.
Natalia Seliutina's new paper in the New Zealand Journal of Geology and Geophysics describes the microstructure of pounamu at grain sizes thinner than a hair, and she says the cause of its toughness is still an open question.

NC State's Jun Liu says the azobenzene lead iodine film is 700 to 10,000 times stiffer than silicone and five times the insulator. The lowest-conductivity claim in the announcement applies to dense, nonporous materials only.
Reality
Researchers put the azobenzene ethyl ammonium lead iodine film at roughly 0.04 watts per metre-kelvin and 700 to 10,000 times silicone's stiffness. Without a thickness figure an engineer cannot specify it.

Yuval Paz, Jay Fineberg and colleagues watched two-dimensional broken patches creep for at least three quarters of a fracture event, a slow stage classical fracture mechanics was never built to describe.

Korean researchers ordered platinum and nickel into a fixed lattice and ran it for four months. The result is a replacement-cost input, but the operating point behind it is missing.
