A nanometer (nm) is a unit of length in the metric system, defined as one billionth (10-9) of a meter (m). The meter is the base unit of length in the International System of Units (SI), making the ...

and hundreds of micrometers in diameter. Within a cell, a DNA double helix is approximately 10 nanometers (nm) wide, whereas the cellular organelle called a nucleus that encloses this DNA can be ...

Skyrmions are nanometer- to micrometer-sized magnetic whirls that exhibit particle-like properties and can be moved efficiently by electrical currents. These properties make skyrmions an excellent ...

This tip, typically 5 micrometers tall with a 10-nanometer apex radius, scans across the surface of a sample. As the sample moves under the tip at velocity v, friction forces (F) between the tip and ...
