A hexagonal structure refers to a shape that has six sides or six angles, like a honeycomb. It's like a pattern where everything is arranged in a symmetrical and geometric way using six equal parts. Full definition
As the perfect hexagonal structures of such monolayers are strained, they enter a subtle «soft mode» — the vibrating atoms slip free of their original configurations and distort towards new structures as the materials break. (sciencedaily.com)
The results showed that there are different possible configurations: Sometimes the particles are tightly packed in a simple hexagonal structure, which is well known from crystals. (sciencedaily.com)
He is known for his «machine sculptures», including a large hexagonal structure emitting an electronic hum, and a motorised mass with pieces of fake planets and meteorites stuck to its arms. (theguardian.com)
