A chemical criterion for rating movies

A measurable criterion now exists for determining the age rating of films. A group of scientists at the Max Planck Institute for Chemistry in Mainz has found that the concentration of isoprene in cinema air correlates with ...

DNA: The next hot material in photonics?

Using DNA from salmon, researchers in South Korea hope to make better biomedical and other photonic devices based on organic thin films. Often used in cancer treatments and health monitoring, thin films have all the capabilities ...

Researchers achieve major breakthrough in flexible electronics

Semiconductors, which are the very basic components of electronic devices, have improved our lives in many ways. They can be found in lighting, displays, solar modules and microprocessors that are installed in almost all ...

Shape-shifting gels get smarter

Gels are useful: we shave, brush our teeth, and fix our hair with them; in the form of soft contact lenses they can even improve our eyesight.

Semiconductor works better when hitched to graphene

Graphene – a one-atom-thick sheet of carbon with highly desirable electrical properties, flexibility and strength – shows great promise for future electronics, advanced solar cells, protective coatings and other uses, ...

Chemists eye improved thin films with metal substitution

The yield so far is small, but chemists at the University of Oregon have developed a low-energy, solution-based mineral substitution process to make a precursor to transparent thin films that could find use in electronics ...
