Super‐Enhancement Focusing of Teflon Spheres

Whole-Teflon microfluidic chips.

Although microfluidics has shown exciting potential, its broad applications are significantly limited by drawbacks of the materials used to make them. In this work, we present a convenient strategy for fabricating whole-Teflon microfluidic chips with integrated valves that show outstanding inertness to various chemicals and extreme resistance against all solvents. Compared with other microfluid...

Proteoglycans: the "Teflon" of the airways?

Proteoglycans are a family of structurally distinct, polyanionic complex carbohydrates composed of repeating disaccharide units. Proteoglycans include heparin, heparan sulphate, chondroitin 4-sulphate, chondroitin 6-sulphate, dermatan sulphate, and hyaluronic acid. Heparin is found in the granules of a subset of mast cells where it is bound to various mediators including histamine. Heparan sulp...

Static Electrification of Teflon by Metals

SUMMARY The electrification of a system consisting of a metal and polytetrafluoro-ethylene (Teflon) has been investigated under relative motion. First, the electrification charge received by the insulator was measured when velocity, radius of curvature of the metal electrode and normal force were varied. The measure ments were performed both in atmospheric pressure and later under vacuum, since...
