▸ The reading
interpretive · artPalladium inhales up to nine hundred times its own volume in hydrogen — foils of it breathe H₂ in and out like sponge cake. That appetite purifies hydrogen streams and fires gasoline-engine catalysis. A metal defined by what it can hold without becoming something else: capacity as character.
The science below is cited as science; the symbolic layers are flagged as interactive art.

▸ Discovery
William Hyde Wollaston — co-discovered with rhodium in platinum residue · England · 1803
▸ Stellar origin
s-process + r-process contributionsSecond-peak s-process element with substantial r-process additions for the neutron-rich isotopes.
▸ Reactivity
Absorbs up to 900 times its volume in hydrogen gasHydrogen storage at room temperature — H atoms slip between Pd's lattice atoms. Heat it back up and the hydrogen comes out.
▸ Applications
- Catalytic converters (gasoline engines)
- Hydrogen purification membranes
- Electronics (multilayer ceramic capacitors)
- Dental alloys and jewelry
▸ Curiosity
Absorbs roughly 900 times its own volume in hydrogen gas — palladium foils breathe H₂ in and out like sponge cake.
