A small team of researchers at the University of Tokyo has created a polymer that can be repaired when broken into two parts by applying a small amount of pressure at room temperature. In their paper published in the journal ...
(Phys.org)—Biological material such as bone and muscle tend to have a wide range of elasticity and rigidity that is different from synthetic materials. In general, with synthetic materials, as stiffness increases, elasticity ...
As 3-D printing has become a mainstream technology, industry and academic researchers have been investigating printable structures that will fold themselves into useful three-dimensional shapes when heated or immersed in ...

(Phys.org)—Drug delivery is tricky because the therapeutic compound needs to be non-toxic and deliver the correct dosage at the correct time. Some therapeutics are chemically unstable and others do not have the correct solubility ...
Imagine a polymer with removable parts that can deliver something to the environment and then be chemically regenerated to function again. Or a polymer that can lift weights, contracting and expanding the way muscles do.
