Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

As graphene's popularity grows as an advanced 'wonder' material, the speed and quality at which it can be manufactured will be paramount. With that in mind, the research group has developed a cleaner and more environmentally friendly method to isolate graphene using carbon dioxide in the form of carbonic acid as the electrolyte solution.

Spray-on electric rainbows: Making safer electrochromic inks

A flick of a switch, and electrochromic films change their colors. Now they can be applied more safely and more commonly thanks to an innovative chemical process that makes them water soluble. They can be sprayed and printed, instead of being confined behind safety implements to handle volatile solvents and their toxic fumes.

Gold shines through properties of nano biosensors

With their remarkable electrical and optical properties, along with biocompatibility, photostability and chemical stability, gold nanoclusters are gaining a foothold in a number of research areas, particularly in biosensing and biolabeling. An international research team has now shown that the fluorescence is an intrinsic property of the gold nanoparticles themselves. The researchers used Au20, gold nanoparticles with a tetrahedral structure.
