Anti-counterfeit polymers work like fingerprints

(Phys.org)—When it comes to tagging items to prove their authenticity, the goal is to stay ahead of counterfeit technology. The best tags are unique, complex, easy to read, and difficult to reproduce. One naturally-occurring ...

New self-stretching material developed

Although most materials slightly expand when heated, there is a new class of rubber-like material that not only self-stretches upon cooling; it reverts back to its original shape when heated, all without physical manipulation.

Fine-tuned supramolecular polymerization

In nature, supramolecular complexes—chain-like structures that are composed of many small units linked mainly by weak non-covalent bonds—are assembled and disassembled in a precisely controlled way. Now, in work published ...

Solar cell polymers with multiplied electrical output

One challenge in improving the efficiency of solar cells is that some of the absorbed light energy is lost as heat. So scientists have been looking to design materials that can convert more of that energy into useful electricity. ...

Two teams pave way for advances in 2D materials

This month's headlines on two-dimensional polymers showed noteworthy headway. "2-D Polymer Crystals Confirmed At Last," said Chemical & Engineering News. "Engineers Make the World's First Verified, 2-Dimensional Polymers," ...

New class of industrial polymers discovered

(Phys.org) —Scientists from IBM Research have successfully discovered a new class of polymer materials that can potentially transform manufacturing and fabrication in the fields of transportation, aerospace, and microelectronics. ...

Water purification at the molecular level

(Phys.org) —Fracking for oil and gas is a dirty business. The process uses millions of gallons of water laced with chemicals and sand. Most of the contaminated water is trucked to treatment plants to be cleaned, which is ...

Gentle caffeine boost for premature babies

Swiss researchers have developed a UV-activated membrane which releases a gentle dose of medication to the skin of a patient. In future those who fear injections will be able to sleep soundly, as will premature babies too, ...

The fix is in: Team studies self-healing polymers

(Phys.org) —A surfboard that seals its own cracks without having to cure in the sun for days. Underwater structures that can be fixed with less work and downtime. Joints that are almost instantly stronger after surgery. ...

'Shape-shifting' material could help reconstruct faces

Injuries, birth defects (such as cleft palates) or surgery to remove a tumor can create gaps in bone that are too large to heal naturally. And when they occur in the head, face or jaw, these bone defects can dramatically ...
