@wanjek.bsky.socialThis technique enhances whiteness without toxic dyes, using #nanotechnology to make surfaces reflect white. And there's a bonus: the coating repeals water.

@oddlytruejp.bsky.social⚪ The whitest surface Kyoto University has ever made is mostly air.
No pigment. No titanium dioxide. No PFAS. Just foam pockets scattering light, the way bare paper makes the white in Hokusai's Great Wave.
20,000 dpi, water-repellent.

Fun rabbithole! 🐇 🕳️
