And if I am concerned, are there any alternatives? I know there are non-stick hydrophobic ceramic coatings available for frying pans etc, but a compatible breadpan and paddle?

Side note, kids clothes at major UK retailers, including and particularly school uniform, are still sometimes 'teflon coated'. Was shocked when I came across this and obviously avoided.

PSA: Star-shaped Bowden tubes are terrible for flexible filaments. Instead of reducing friction, they can increase it—because the filament gets pushed into the star “corners” under tension.

Chemists discover clean and green way to recycle Teflon

New research demonstrates a simple, eco-friendly method to break down Teflon—one of the world's most durable plastics—into useful chemical building blocks.

Oh, look! I updated a thing! Now a *set* of couplers to connect PTFE tubing for printers, dryboxes, etc.

(marvy. yet another potential source for #PTFE contamination in a new 'stretchable fabric'?)

"…researchers in 2D semiconductors tend not to engage with #ionomer chemistry, UCLA's energy and 2D optoelectronics subgroup constantly exchange ideas about materials processing.

That overlap sparked the idea of combining two "common" materials from different worlds—#Nafion and MoS2—and the unexpected synergy made the breakthrough possible."

Stretchable light-emitting material holds promise for photon-based devices

A research team led by the California NanoSystems Institute at UCLA, or CNSI, demonstrated a new type of light-emitting material expected to be suitable for photonics—devices based on light in the same way that today's electronics are based on electrical signals.
