The result is a “Russian-doll” droplet that, if the correct oily and aqueous liquids are chosen, can be made permanent by curing some of its layers into transparent polymers using ultraviolet light.
Typically, fragile ceramics or rigid polymers are used in surgery to fix broken, old or cancer-damaged bones.
High voltage cables are typically insulated with special water-resistant polymers that have high-dielectric strength.
On the basic of it, fluoride polymers were applied to spin, leather, dope and so on.
The mobile lavatory consists of a plastic bag fitted with absorbent polymers that turn urine into a gel.
Previous researchers had tried to sidestep this problem by using gel polymers for the electrolyte, but even these contained flammable solvents.
The researchers are now doing that, and they are also exploring the use of different polymers that could replace PEG and offer more control over cell placement.
