Imagine having a picture on your wall that completely changes when the room gets too warm. Engineers at MIT have created a new printing technology called Thermochromorph to make full-color images that ...

Mercury is one of the only elements that's liquid at room temperature and it's also very dense. It's even denser than lead and is known to be very toxic, but as a liquid, it's kind of ok to touch.

Mercury, which is liquid at room temperature, was used in a wide range of products, such as fluorescent lamps, thermometers and batteries. But it is also highly toxic. Mercury poisoning caused by ...

Until fairly recently, when we needed to know the temperature precisely, reliably, and over a wide range we used mercury thermometers. The devices themselves were marvels of instrumentation ...

Starting with mercury, he observed that at 4.2 K ... Presumably, if you had room-temperature superconductors, you could form Josephson junctions with them, and all of these devices would become ...
