A new approach analyzing car paint based on the medical imaging technique optical coherence tomography (OCT) provides the car industry with a practical way to automatically analyze these metal flakes, which until now have been difficult to image, in order to improve the efficiency of the automotive finishing process.

When certain materials are cooled below a critical temperature they become superconductors, with zero electrical resistance. An international research team observed an unusual electronic state in new superconductor chromium arsenide. This finding could prove useful in future superconductor research and material design. The study was published on June 5 in Nature Communications.

South Korea's Ulsan National Institute of Science and Technology has presented a new cost-efficient way to produce inorganic-organic hybrid perovskite solar cells (PSCs) which sets a new world-record efficiency performance of 22.1 %.

The target of large, cheap and quick graphene synthesis achieved: 5 x 50 cm2 and beyond.

Researchers have developed a new synthesis route for alternative catalysts of noble metals.

A team including Berkeley Lab scientists has developed a faster and easier way to make a class of sulfur-containing plastics that will lower the cost of large-scale production.

For the first time an international team realized direct writing of silver nanostructures using an electron beam applied to a substrate. Silver nanostructures have the potential to concentrate visible light at the nanoscale. Potential applications include sensor design to detect extremely small traces of specific molecules, as well as devices for optical information processing.

Scientists at Nagoya University have developed a new way to make stimuli-responsive materials in a predictable manner. They used this method to design a new material, a mixture of carbon nanorings and iodine, which conducts electricity and emits white light when exposed to electricity. The team's new approach could help generate a range of reliable stimuli-responsive materials, which can be used in memory devices, artificial muscles and drug delivery systems, among other applications.

Urban food demand in the Amazon could be hitting wildlife up to 1,000 km away from the city, according to new research.
