Turning up the heat on antibacterial-resistant diseases

Photothermal therapy (PTT) is a proposed treatment for diseases like antibacterial-resistant infections and cancer, but despite over a decade of research, scientists have been unable to find a safe and effective chemical ...

Molecules move faster on a rough terrain

Roughness, the presence of irregularities on a surface, is commonly associated with slower motion and stickiness. This is true at different length scales: at human size (1 meter), it takes longer to walk along a path that ...

Liquid flow is influenced by a quantum effect in water

Researchers at EPFL have discovered that the viscosity of solutions of electrically charged polymers dissolved in water is influenced by a quantum effect. This tiny quantum effect influences the way water molecules interact ...

New polymer releases molecular cargo in response to force

Caltech scientists have developed a new kind of polymer that can carry a chemical payload as part of its molecular structure and release it in response to mechanical stress. The chemical system they have developed could one ...

Synthesis of helical ladder polymers

Researchers at Kanazawa University synthesized helical ladder polymers with a well-defined cyclic repeating unit and one-handed helical geometry, as they reported in the Journal of the American Chemical Society.

Polymer reversibly glows white when stretched

Researchers at the University of Fribourg's Adolphe Merkle Institute (AMI) and Hokkaido University in Japan have developed a method to tailor the properties of stress-indicating molecules that can be integrated into polymers ...
