Nanotechnology Now Our NanoNews Digest Sponsors Home > Press > Magnetism drives metals to insulators in new experiment: Study provides new tools to probe novel spintronic devices An illustration of two domains (blue and orange) divided by a domain wall (white area) in a material. The magnetic order is designated with organized arrows (electron spins) while the colors represent two different domains (but the same magnetic order). In the material pictured here, the domain walls are conductive and the domains are insulating. CREDIT Yejun Fang Abstract: Like all metals, silver, copper, and gold a...

Nanotechnology Now Our NanoNews Digest Sponsors Home > Press > Thin is now in to turn terahertz polarization: Rice lab’s discovery of ‘magic angle’ builds on its ultrathin, highly aligned nanotube films Rice University physicists have made unique broadband polarization rotators with ultrathin carbon nanotube films. The films optically rotate polarized light output by 90 degrees, but only when the input light’s polarization is at a specific angle with respect to the nanotube alignment direction: the “magic angle.” (Credit: Kono Laboratory/Rice University) Abstract: It’s always good when...

Nanotechnology Now Home > Press > You're so vein: Scientists discover faster way to manufacture vascular materials Synchronized manufacturing of a bioinspired structure with a hierarchical vascular network. CREDIT Mayank Garg, Nancy Sottos, Jeff Moore, and Phillipe Guebelle Abstract: Developing self-healing materials is nothing new for Nancy Sottos, lead of the Autonomous Materials Systems Group at the Beckman Institute for Advanced Science and Technology at the University of Illinois Urbana-Champaign.

POSS-peptoid molecules self-assemble into rhomboid-shaped nanocrystals. CREDIT (Illustration by Stephanie King | Pacific Northwest National Laboratory) Abstract: Inspired by nature, researchers at Pacific Northwest National Laboratory (PNNL), along with collaborators from Washington State University, created a novel material capable of capturing light energy. This material provides a highly efficient artificial light-harvesting system with potential applications in photovoltaics and bioimaging. Harvesting light like nature does:Synthesizing a new class of bio-inspired, light-capturing nanomat...
