A single organic device reconfigures as transistor, rectifier and logic gate, offering compact circuits with higher ...

(Nanowerk Spotlight) Logic gates, especially Boolean logic gates, are the fundamental building blocks of today's computers built with silicon-based circuitry; without them, digital information could ...

Light-based logic: The optical chirality logic gate is made of a nonlinear optical material that generates an output signal that’s dependent on the chirality of the two input beams. (Courtesy: Yi ...

DNA is often referred to as the building block of life. Now scientists from Imperial College London have demonstrated that DNA (and bacteria) can be used to create the fundamental building blocks of a ...

The ability for cells to control gene expression in response to changing conditions is crucial for their survival. People spend their entire careers teasing apart these mechanisms, many of which are ...

A logic gate is an electronic component (or set of them) that performs a logic operation, in which the binary values 0 and 1 are represented with two different voltage values, as seen in the previous ...

A collection of transistors and resistors that implement Boolean logic operations in a digital circuit. Logic gates have one or two 0 or 1 inputs but only one 0 or 1 output as in the following ...

Towards ultrafast logic gates (Courtesy: University of Rochester illustration / Michael Osadciw) The first logic gate to operate at femtosecond timescales could help usher in an era of information ...
