The simple cubic unit cell is delineated by eight atoms, which mark the actual cube. These are corner atoms, so each one only contributes one eighth of an atom to the unit cell, thus giving us only ...

Cells are the smallest unit of life. Cells in multicellular plants and animals are arranged into tissues, organs and organ systems. Cells. Tissues. Organs. Organ systems. And the organism itself ...

Graphene — a single layer of carbon atoms arranged in a honeycomb lattice ... Although the efficiency of their graphene-on-silicon solar cell is currently quite low, the researchers envisage ...

A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their ...

When sunlight hits the cells, it knocks electrons loose from their atoms. As the electrons flow through the cell, they generate electricity. On a much larger scale, solar-thermal power plants ...

A new strategy for measuring magnetic fields could one day lead to a host of new quantum sensors—from tools that might map out the activity of the human brain to devices that could help airplane ...
