  • Consumers, nanotechnology and responsibilities: Operationalizing the risk society
    • Risks are high on the agenda in our society, to the extent that we might refer to the society as a risk society. Our society experiences emerging technologies, like nanotechnology. Different actors respond to this in a variety of ways. Among these are the consumers, an important, but neglected category of actors in this context. Arguably it is in our role as consumers we first encountered nanotechnology, in the form of nano-enabled products at the consumers market. What consumers think and do, reacting to the mixed messages about benefits and risks of nanotechnology, contributes to how the risk society (with regard to nanotechnology) is developed, and in that sense becomes operationalized. The theme of this thesis is not just the responses of consumers (and how others perceive these) to the introduction of nanotechnology, but also a case study of how the risk society can be operationalized.

  • Availability of hydrogen controls chemical structure of graphene oxide
    • A new study shows that the availability of hydrogen plays a significant role in determining the chemical and structural makeup of graphene oxide, a material that has potential uses in nano-electronics, nano-electromechanical systems, sensing, composites, optics, catalysis and energy storage.
  • Sequence it ... and they will come
    • Rapid DNA sequencing may soon become a routine part of each individual’s medical record, providing enormous information previously sequestered in the human genome’s 3 billion nucleotide bases. This week’s NEWSFOCUS section of the journal Science describes recent advances in sequencing technology.
  • Dopant gives graphene solar cells highest efficiency yet
    • (Phys.org) -- By taking advantage of graphene’s favorable electrical and optical properties, and then adding an organic dopant, researchers have achieved the highest power conversion efficiency yet for a graphene-based solar cell. The 1.9% power conversion efficiency of the undoped devices increases by more than four times to 8.6% after doping.
  • Nanomedicine: Quantum dots appear safe in pioneering study on primates
    • A pioneering study to gauge the toxicity of quantum dots in primates has found the tiny crystals to be safe over a one-year period, a hopeful outcome for doctors and scientists seeking new ways to battle diseases like cancer through nanomedicine.
  • Synthetic scent hounds: Nanostructured sensor for detection of very low concentrations of explosive
    • To prevent terrorist attacks at airports, it would be helpful to detect extremely low concentrations of explosives easily and reliably. Despite the development of various sensor technologies, dogs continue to be the most efficient detectors. In the journal Angewandte Chemie, a German and French team has now described a type of micromechanical sensor with a structure derived from the sense organs of butterflies.
  • Using graphene, scientists develop a less toxic way to rust-proof steel

  • Electron hopping in graphene oxide leads to highly sensitive sensing
    • (Phys.org) -- Graphene has many promising applications on its own, but pairing the two-dimensional material with the semiconductor titanium dioxide (TiO2) extends its capabilities even further. A team of chemists at the University of Notre Dame in Notre Dame, Indiana, has demonstrated that graphene oxide (GO)-TiO2 films, when illuminated, cause electrons to hop from one side of the film to the other. When adding silver ions to the picture, this electron hopping can create films that have a semiconductor on one side of the GO and metal on the other. The resulting semiconductor-graphene-metal (SGM) films could serve as highly sensitive chemical sensors.
