Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

Optical computing and logic circuits represent a transformative approach to information processing, utilising light rather than electrons to execute computational tasks. This paradigm leverages the ...

Researchers have built logic circuits, the heart of all electronic gadgets, on molybdenum disulfide films that are two molecular layers thick (Nano Lett., DOI: 10.1021/nl302015v). The devices are the ...

Since 1972, scientists have known there are four basic circuit components, but if you’ve spent any time in an electrical engineering classroom, you probably only have experience with three: capacitor, ...

The myriad processes occurring in biological cells may seem unbelievably complex at first glance. And yet, in principle, they are merely a logical succession of events, and could even be used to form ...

In a proof-of-concept study, researchers have created self-assembled, protein-based circuits that can perform simple logic functions. The work demonstrates that it is possible to create stable digital ...

Multiple droplets of a magnetic fluid have been used to create all of the fundamental logic circuits within a computer. Created by researchers in the US, the circuits are made by having the ...

DNA nanostructures constitute attractive devices for logic computing and nanomechanics. An emerging interest is to integrate these two fields and devise intelligent DNA nanorobots. Here we report a ...

We’ve all heard of the dangers of static electricity when dealing with electronics, and we all take the proper precautions when working with static-sensitive components — don’t we? But as much as we ...
