Researchers have developed a novel strategy to produce single-walled carbon nanotubes with specific chirality by applying a new family of catalysts, which has great applications and influence in nanoelectornics and related fields.
Scientists have discovered that molybdenum trioxide nanoparticles oxidize sulfite to sulfate in liver cells in analogy to the enzyme sulfite oxidase. The functionalized Molybdenum trioxide nanoparticles can cross the cellular membrane and accumulate at the mitochondria, where they can recover the activity of sulfite oxidase.
Physicists have solved a mystery that has puzzled scientists for half a century. They show with the help of powerful microscopes that the distance between graphite oxide layers gradually increases when water molecules are added.
The antibacterial properties of silver-coated textiles are popular in the fields of sport and medicine. A team at Empa has now investigated how different silver coatings behave in the washing machine, and they have discovered something important: textiles with nano-coatings release fewer nanoparticles into the washing water than those with normal coatings.
Physicists have used a scanning tunneling microscope to create quantum dots with identical, deterministic sizes. The perfect reproducibility of these dots opens the door to quantum dot architectures completely free of uncontrolled variations, an important goal for technologies from nanophotonics to quantum information processing as well as for fundamental studies.
This achievement paves the way toward smart composites that enable continued and automatic monitoring of the structural health of the composite material in for example tidal blades, wind turbines, airplanes or marine structures.
For his doctoral dissertation in the Goldman Superconductivity Research Group at the University of Minnesota, Yu Chen, now a postdoctoral researcher at UC Santa Barbara, developed a novel way to fabricate superconducting nanocircuitry. However, the extremely small zinc nanowires he designed did some unexpected - and sort of funky - things.
