Graphene paper takes shape and walks

Inspired by origami, researchers at Donghua University in Shanghai, China, have built self-folding paper from nanosheets of graphene oxide. The new paper bends in response to light or heat, can “walk” and even turn corners. The material could be used in a wide range of applications, including sensing, artificial muscles and robotics…….. http://nanotechweb.org/cws/article/tech/63120 The graphene […]

Light-responsive nanoparticles bring heart rhythm back to normal

Light-responsive nanoparticles that can selectively destroy heart muscle cells while leaving nearby healthy cells intact have been designed by researchers at the University of Michigan in Ann Arbour. The new technique could help overcome some of the limitations of catheter ablation – a common treatment for patients with arrhythmia…….. http://nanotechweb.org/cws/article/tech/63125 Sparing fibroblasts and vascular cells

Shedding more light on graphene moiré plasmons

Researchers at the University of California at San Diego (UCSD) are the first to have used infrared nano-imaging to study how surface plasmons (collective oscillations of electrons) propagate in “moiré-patterned” graphene grown on hexagonal boron nitride. The observations, which reveal new collective plasmon modes, could help in the development of advanced plasmonic circuits for novel […]

Deep-blue PHOLEDs brighten up

Researchers at the University of Michigan, Ann Arbor, in the US are the first to have fabricated phosphorescent organic light-emitting diodes (PHOLEDs) that emit both very bright and deep blue light. The new devices fulfill the most stringent requirements for blue pixel displays and other lighting applications…. http://nanotechweb.org/cws/article/tech/63009 Electrophosphorescent device characteristics

Chemical treatments protect cantilevers

Since the first reports of atomic force microscopy 30 years ago, single-crystal silicon cantilevers have attracted much interest for high-sensitivity imaging and sensing. The energy dissipation during the cantilever oscillation that is central to these technologies is one of the limiting factors preventing higher sensitivities and spatial resolutions. Now researchers have traced these losses to […]
