Inspired by ideas and techniques for cooling atomic gases, an experiment demonstrates how the temperature of micrometre-scale electronic devices can be lowered using solid-state quantum circuits.

Chip manufacturers are forever trying to squeeze more and more components onto a single chip. The smallest features on today’s microchips are about 100 nanometers in width, whereas a carbon nanotube ...

The supply voltage is shared between components in a series circuit, so the sum of the voltages across all of the components in a series circuit is equal to the supply voltage, \({V_s}\). if two ...

Series and parallel circuits Current in series circuits Voltage across components in a series circuit Current in parallel circuits Voltage across components in a ...

Chemistry isn't necessarily the most photogenic of disciplines, but 10 years ago, George M. Whitesides' group at Harvard University grabbed the chemical community's attention with a picture of a ...

Through-hole assembly means bending leads on components and putting the leads through holes in the circuit board, then soldering them in place, and trimming the wires. That took up too much space and ...
