There are so many materials properties leading to memory that a unifying description seems impossible. However, it is easy to show that the majority of two-terminal electronic devices based on memory materials and systems behave simply as, or as a combination of, memristors, memcapacitors, and meminductors.

The opportunity to use solid-state thermoelectrics for waste heat recovery has reinvigorated the field of thermoelectrics in tackling the challenges of energy sustainability. While thermoelectric generators have decades of proven reliability in space, from the 1960s to the present, terrestrial uses have so far been limited to niche applications on Earth because of a relatively low material efficiency.

In materials science, collaborations tend to be limited to the cooperation of several small research groups. Meanwhile, in the world of particle physics, it's an entirely different story. Markus Nordberg and Fabiola Gianotti from the LHC's ATLAS experiment, discuss the rewards and difficulties of large scale collaboration.
