New polymer creates safer fuels

Before embarking on a transcontinental journey, jet airplanes fill up with tens of thousands of gallons of fuel. In the event of a crash, such large quantities of fuel increase the severity of an explosion upon impact. Researchers ...

Antimicrobial film for future implants

The implantation of medical devices is not without risks. Bacterial or fungal infections can occur and the body's strong immune response may lead to the rejection of the implant. Researchers at Unit 1121 "Biomaterials and ...

New fluorescent polymer makes deformation visible

A new type of polymer can show that it has changed shape. After exposure to UV light, the chain-like molecules emit a different colour of light. This opens a new pathway for research into how viruses function in a cell and ...

Anti-counterfeit polymers work like fingerprints

(—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 ...

Recipe for antibacterial plastic: Plastic plus egg whites

Bioplastics made from protein sources such as albumin and whey have shown significant antibacterial properties, findings that could eventually lead to their use in plastics used in medical applications such as wound healing ...

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. ...

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 ...
