Nanotechnology researchers create quantum dots with single-atom precision

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.

'Compressive sensing' provides new approach to measuring a quantum system

In quantum physics, momentum and position are an example of conjugate variables. This means they are connected by Heisenberg's Uncertainty Principle, which says that both quantities cannot be simultaneously measured precisely. Recently, researchers have been developing novel techniques, such as 'weak measurement,' to measure both at the same time. Now Rochester physicists have shown that a technique called compressive sensing offers a way to measure both variables at the same time, without violating the Uncertainty Principle.

Testing nano materials to build consumer confidence

Engineered nano materials (ENM) are being used more and more in a variety of commercial products. However, there is also concern that some of these properties may be harmful to humans. The FP7-funded research project, NANOSOLUTIONS aims to address this problem by classifying the safety potential of a variety of ENMs.

Watching nanofluids flow in 4D real-time (w/video)

Researchers have applied a new imaging technique called four-dimensional (4D) electron microscopy to the nanofluid dynamics problem. They describe how they visualized and monitored the flow of molten lead within a single zinc oxide nanotube in real time and space.
