Materials scientists in California have made a special metallic glass with a strength and toughness greater than any known material, using a recipe that could yield a new method for materials fabrication.
The glass, a microalloy made of palladium, has a chemical structure that counteracts the inherent brittleness of glass but maintains its strength. It’s not very dense and it is more lightweight than steel, with comparable heft to an aluminum or titanium alloy.
Precious metals in your car burn up the dirty exhaust, with no flame to be seen

More Than Meets the Eye
Invisible propane gas flows, unlit, from a torch. On hitting the rhodium-studded ceramic honeycomb from a catalytic converter, it burns without flame, heating the ceramic red-hot.
To a chemist, burning means the rapid combination of a fuel with oxygen, called oxidation. You might say, for instance, “Oh, no, we didn’t have a fire at the nuclear power plant, we just had a ‘rapid oxidation event,’ ” a phrase that won officials at Three Mile Island the Doublespeak Award in 1979.
