Future intent: Would you let an automated car do the driving?

Researchers have surveyed more than 2000 drivers across Australia, France and Sweden for two separate studies investigating what people think about travelling in automated cars. The first international study found French drivers were more likely to one day buy an automated car than drivers in Australia or Sweden. The second study surveyed local Queensland drivers and identified what they saw as the pros and cons of letting a car drive itself.

New silk materials can wrinkle into detailed patterns, then unwrinkle to be 'reprinted'

October 8, 2019 0 Comments 3-D Printing, Artificial intelligence, Computer Graphics, Computer Science, Information Technology, Materials Science, Nature of Water, Textiles and Clothing

Engineers have developed silk materials that can wrinkle into highly detailed patterns — including words, textures and images as intricate as a QR code or a fingerprint. The patterns are stable, but can be erased by flooding the surface of the silk with vapor, allowing the surface to be printed again. The researchers demonstrate multiple examples of the silk wrinkle patterns, and envision a wide range of potential applications for optical electronic devices.

The fast dance of electron spins

October 4, 2019 0 Comments Chemistry, Computer Modeling, Computer Science, Distributed Computing, Inorganic Chemistry, Physics, Spintronics, Spintronics Research

Metal complexes show a fascinating behavior in their interactions with light, which for example is utilized in organic light emitting diodes, solar cells, quantum computers, or even in cancer therapy. In many of these applications, the electron spin, a kind of inherent rotation of the electrons, plays an important role. Researchers succeeded in simulating the extremely fast spin flip processes that are triggered by the light absorption of metal complexes.
