The Captivating World of Quasicrystals: A Nobel Discovery 🌌🔬
What Are Quasicrystals?
Quasicrystals are a remarkable class of materials characterized by their unique atomic arrangement, which exhibits long-range order but lacks translational symmetry. Unlike conventional crystals,which have repeating patterns,quasicrystals possess a non-repeating,complex structure that can be both stunning and mind-boggling.
The Discovery of Quasicrystals
The discovery of quasicrystals dates back to 1982 when Dan Shechtman,an Israeli scientist,observed these intriguing structures while examining an alloy of aluminum and manganese under an electron microscope.His findings challenged the conventional understanding of crystallography, leading to a groundbreaking discovery that earned him the Nobel Prize in Chemistry in 2011.
The Structure of Quasicrystals
Quasicrystals manifest unique symmetries-most notably, they can exhibit five-fold symmetry. This is impossible in traditional crystalline structures due to Bravais lattices. The unique atom arrangements give rise to various fascinating structures, including:
