Multiplex detection of silver and molybdenum nanoparticles

Researchers investigated the oxidative response of both Ag and Mo nanoparticles by using differential pulse voltammetry. After identifying the individual responses, the two materials were combined on a single electrode for simultaneous detection.

Researchers time plasmon-generated electrons moving from nanorods to graphene

Plasmonic nanoparticles developed at Rice University are becoming known for their ability to turn light into heat, but how to use them to generate electricity is not nearly as well understood. Scientists at Rice are working on that, too. They suggest that the extraction of electrons generated by surface plasmons in metal nanoparticles may be optimized.

Scientists discover long-awaited synthetic particle

Researchers at Aalto University and Amherst College have now created and photographed synthetic magnetic monopoles under laboratory conditions. These observations lay the foundation for the underlying structure of the natural magnetic monopole - the detection of which would be a revolutionary event comparable to the discovery of the electron.

Cell membrane model studied as future diagnostic tool

Researchers have used a NIST-developed laboratory model of a simplified cell membrane to accurately detect and measure a protein associated with a serious gynecological disease, bacterial vaginosis, at extraordinarily low concentrations. The work illustrates how the artificial membrane could be used to improve disease diagnosis.

Learning more about piezoelectric

Though piezoelectrics are a widely used technology, there are major gaps in our understanding of how they work. Now researchers at the National Institute of Standards and Technology (NIST) and Canada's Simon Fraser University believe they've learned why one of the main classes of these materials, known as relaxors, behaves in distinctly different ways from the rest and exhibit the largest piezoelectric effect.
