Spinning atoms in light crystals

After more than 40 years of intense research, experimental physicists still seek to explore the rich behaviour of electrons confined to a two-dimensional crystalline structure exposed to large magnetic fields. Now a team of scientists developed a new experimental method to simulate these systems using a crystal made of neutral atoms and laser light.

Nanoporous membranes clear the way for chip-sized pumps

Electroosmotic pumps (EOPs), devices in which fluids appear to magically move through porous media in the presence of an electric field, are ideal because they can be readily miniaturized. EOPs however, require bulky, external power sources, which defeats the concept of portability. But a super-thin silicon membrane could now make it possible to drastically shrink the power source, paving the way for diagnostic devices the size of a credit card.

Using genetic algorithms to discover new nanostructured materials

Researchers have developed a new approach to designing novel nanostructured materials through an inverse design framework using genetic algorithms. The study is the first to demonstrate the application of this methodology to the design of self-assembled nanostructures, and could help speed up the materials discovery process. It also shows the potential of machine learning and 'big data' approaches.

Workshop on 'Grouping and Read-Across for Nanomaterials'

This NIA Symposium will provide a discussion platform for exchange between companies and policy makers, in order to allow for a proactive approach in meeting the regulators' requirements for grouping- and read-across-approaches to nanomaterials, without hampering innovation and commercialization.

Scientists to gain from view inside of fuel cells with nano X-ray CT

Powerful scanners that give scientists a direct line of sight into hydrogen fuel cells are the latest tools Simon Fraser University researchers will use to help create more durable, lower-cost fuel cells. Use of these fuel cells in vehicles can substantially reduce harmful emissions in the transportation sector. The new Nano X-ray Computed Tomography tools will become part of a nationally unique fuel cell testing and characterization facility.
