4-D imaging with liquid crystal microlenses

Most images captured by a camera lens are flat and two dimensional. Increasingly, 3-D imaging technologies are providing the crucial context of depth for scientific and medical applications. 4-D imaging, which adds information ...

Novel nanostructures could make smartphones more efficient

EU-funded researchers and partners are pushing the boundaries of the laws of physics, developing nanocomposite materials and nanoelectronic circuits to greatly improve energy, thermal and computing performance. This could ...

Promising discovery could lead to a better, cheaper solar cell

McGill University researchers have gained tantalizing new insights into the properties of perovskites, one of the world's most promising materials in the quest to produce a more efficient, robust and cheaper solar cell.

Schools of molecular 'fish' could improve display screens

Take a dive into what may be the world's smallest coral reef. Scientists at the University of Colorado Boulder are using a type of material called liquid crystals to create incredibly small, swirling schools of "fish," according ...
