(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 ...

The Boolean logic gates AND, OR and NOT comprise transistors, which are on/off switches wired together. Gates have one or two inputs but only one output, and they are wired in patterns that make up ...

Transistors wired in series and parallel patterns make up "gates," which accept binary input (0 = no pulse; 1 = pulse) and generate binary output. Although AND requires both inputs to be 1 in order to ...

Scientists have engineered cells that behave like AND and OR Boolean logic gates, producing an output based on one or more unique inputs. This feat could eventually help researchers create computers ...

(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, ...

Johns Hopkins scientists have engineered cells that behave like AND and OR Boolean logic gates, producing an output based on one or more unique inputs. This feat, published in the May issue of Nature ...
