Quasicrystals are non-periodic solids that were discovered in 1982 by Dan Shechtman, Nobel Prize Laureate in Chemistry 2011. The underlying mathematics, known as the theory of aperiodic order, is the ...
Nanopatterning of subwavelength features has already been achieved by silk replication of aperiodic structures consisting of an arrangement of 200-nm-diameter holes separated by as little as 30 nm ...
On the spectrum, these correspond to each peak. On the other hand, speech sounds can also be aperiodic when analysing them acoustically. This means that they do not have a regular repeating pattern, ...
A study reveals the influence of grain boundaries on materials, showing how iron levels change icosahedral structures and affect material properties. Through microscopy and simulations, researchers ...
