(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 ...

(a) Schematic illustration of logic gate NOR built by cascaded OR and NOT gates. (b) Optical image of the designed Ag NW structure. (c) Schematics of experimental setup. BS, beamsplitter; OBJ, ...

We’re going to focus on three fundamental operations - NOT, AND, and OR. Today, Carrie Anne is going to take a look at how those transistors we talked about last episode can be used to perform complex ...

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 ...

Finally, E. coli is good for something other than making you regret not washing that lettuce better. Boffins at the Imperial College London have employed the bacteria as living Boolean logic ...
