Sorry, cosmic acceleration, this was not your year.   The Nobel Prize in Physics 2010 was awarded jointly to Andre Geim and Konstantin Novoselov "for groundbreaking experiments regarding the two-dimensional material graphene".

Without question ultrathin carbon is here to stay and a lot of terrific work is done with it every month.  Bendable computer screens and ultralight materials could all result from graphene research.
Researchers have made environmentally-friendlier bricks that are also stronger than traditional ones.   That is a big win for everyone.

Untreated clay was one of the earliest building materials to be used by humankind. The oldest examples of this can be found in houses in the Near East dating from between 11,000 and 12,000 years ago, while earthy material mixed with plants and pebbles to make them stronger has also been found in certain archaeological deposits from 1,400BC  in Sardinia, Italy.
