Shapes
Nanostructures of virtually any 3-dimensional shape can be deposited using computer-controlled scanning of electron beam. Only the starting point has to be attached to the substrate, the rest of the structure can be free standing. The achieved shapes and devices are remarkable:
- World smallest magnet
- Fractal nanotrees
- Nanoloops (potential nanoSQUID device)
- Superconducting nanowires

Famous quotes containing the word shapes:
“Incarnate devil in a talking snake,
The central plains of Asia in his garden,
In shaping-time the circle stung awake,
In shapes of sin forked out the bearded apple....”
—Dylan Thomas (1914–1953)
“I write about violence as naturally as Jane Austen wrote about manners. Violence shapes and obsesses our society, and if we do not stop being violent we have no future.”
—Edward Bond (b. 1934)
“Taught from their infancy that beauty is woman’s sceptre, the mind shapes itself to the body, and, roaming round its gilt cage, only seeks to adorn its prison. Men have various employments and pursuits which engage their attention, and give a character to the opening mind; but women, confined to one, and having their thoughts constantly directed to the most insignificant part of themselves, seldom extend their views beyond the triumph of the hour.”
—Mary Wollstonecraft (1759–1797)
