Corning's Gorilla Glass achieves its strength through ion exchange — dunking hot glass in molten KNO3 swaps Na+ for larger K+ ions, compressing the surface layer. Chemical tempering at the ionic level. Your phone screen is a chemistry marvel.

Xylem's ozone generators use corona discharge to produce O3 for water disinfection — no chemical residue, no chlorination byproducts. Advanced oxidation processes destroy pharmaceuticals and PFAS in wastewater. Chemistry cleaning chemistry.

Froth flotation chemistry separates copper ore from gangue — xanthate collectors selectively bind to sulfide minerals, attaching them to air bubbles. Without these molecules, battery-grade copper stays in the rock.
