Graphene and other carbon nanomaterials can replace scarce metals

ScienceDaily.com: Nanotechnology News - 19 сентября, 2017 - 16:10
Scarce metals are found in a wide range of everyday objects around us. They are complicated to extract, difficult to recycle and so rare that several of them have become "conflict minerals" which can promote conflicts and oppression. New research shows that there are potential technology-based solutions that can replace many of the metals with carbon nanomaterials, such as graphene.

Just squeeze in -- when spaces are tight, nature loosens its laws

ScienceDaily.com: Nanotechnology News - 18 сентября, 2017 - 19:35
It turns out that when they're in a hurry and space is limited, ions, like people, will find a way to cram in -- even if that means defying nature's norms. Researchers have now shown that the charged particles will actually forgo their 'opposites attract' behavior, called Coulombic ordering, when confined in the tiny pores of a nanomaterial.

Scalable process discovered to produce structural colors inspired by bird feathers

ScienceDaily.com: Nanotechnology News - 18 сентября, 2017 - 19:35
Researchers made nano-sized balls of melanin aggregate into clusters called supraballs. Melanin appears black in individual nanoparticles. But altering spacing of the nanoparticles in the ball affects how the particles scatter light. A thin silica coating on the outside of melanin nanoparticles acts like a bumper, limiting how close the particles can pack together. Varying the diameter of the melanin core and the thickness of the silica shell creates supraballs in a range of colors.
