These home made transistors sacrifice a point contact diode to get the small chip of germanium, and form the other two electrodes with metal foil glued to paper. Given that germanium point contact ...

For example, you can insert a resistor, a capacitor, an inductor, a diode, or a transistor and get a readout of which pin is which. It seems like magic, but [Andreas Spiess] did the research on ...

Aluminum foil is an indispensable item in nearly every household. It's versatile: You can use it for everything from foil packet recipes to cleaning your grill. The handy product comes equipped with a ...

From household chores and entertaining to garden care and camping, your trusty roll of aluminum foil is here to make life easier. Right alongside plastic wrap and parchment paper, aluminum foil enjoys ...

Why it matters: Silicon transistors are great, but just like any other object in the physical world, they are held back by a few limitations. The laws of physics put a bottleneck on performance ...

We won’t get foiled again. Americans think nothing of using aluminum foil to prepare breakfast, lunch and dinner — but there are some risks involved, according to food safety experts.

MIT researchers have developed a new type of 3D transistor that could be more energy-efficient and powerful than current silicon-based transistors. The novel 3D transistors have been designed ...

But there’s never been a foil like the one beneath Red Bull athlete Peter Salzmann’s wingsuit. It helped the Austrian smash records for unpowered human flight. A wingsuit is a one-piece ...

The never-before-seen technology is the result of collaborative development between Salzmann and wingsuit foil developer Andreas Podlipnik, as well as support from the engineering team at Red Bull ...
