A team of researchers led by the University of Pittsburgh demonstrated a programmable superconducting diode at the LaAlO 3 /KTaO 3 (LAO/KTO) interface, an advance that holds potential to enhance/help ...

There is a near-endless number of resources to find in Marathon, and knowing where the real value lies is a trick in and of itself. In this guide, I'll show you where to go to find the all-important ...

We might tend to take the word “diode” for granted if we’re thinking of a “diode” as just a two-lead or two-terminal device that gets used in this or that place for this or that purpose. It can become ...

CEO Sam Altman called a strange graph in its GPT-5 presentation a ‘mega chart screwup.’ CEO Sam Altman called a strange graph in its GPT-5 presentation a ‘mega chart screwup.’ is a senior reporter ...

A diode is a device that allows electric current to flow in only one direction, from its anode towards its cathode but not the other way around. There is plenty of online material explaining diode ...

In any electronic circuit, the energy stored in an inductor must be properly channeled in the event of switching. This FAQ explains how a freewheeling diode can help achieve smooth inductor ...

If you’ve been making the same commute for a long time, you’ve probably settled on what seems like the best route. But “best” is a slippery concept. Perhaps one day there’s an accident or road closure ...

[Julian] knows that real diodes you can buy don’t work exactly like we say they do. That’s actually pretty common. We routinely ignore things like wire resistance and source resistance in batteries.

The superconducting diode effect allows for nonreciprocal, dissipationless transport. It has the potential to enhance transfer current efficiency compared to the traditional semiconducting equivalent ...
