Quantum optics with microwaves

Physicists at ETH Zurich have demonstrated one of the quintessential effects of quantum optics - known as the Hong-Ou-Mandel effect - with microwaves, whose frequency is 100000 times lower than that of visible light. The experiment takes quantum optics into a new frequency regime and could eventually lead to new technological applications.

Imaging nanoscale polarization in ferroelectrics with coherent X-rays

Seeing the fine-scale properties of materials relevant to nanotechnology is a prominent challenge that currently can be met only under ideal conditions. Coherent X-ray imaging promises to greatly expand the range of materials and environments in which these important properties can be observed.

New graphene sensors could vastly improve air and water quality testing

Researchers at CRANN, Ireland's leading nanoscience institute, funded by Science Foundation Ireland and based at Trinity College Dublin, have discovered a new concept in sensor-development. The research provides a completely new platform for the development of sensors worldwide and will lead to low-energy, remotely powered sensors that have greater detection capacity than those currently available.

Composite organic/inorganic thermoelectric is more than sum of its parts

Scientists have discovered highly conductive polymer behavior occurring at a polymer/nanocrystal interface. The composite organic/inorganic material is a thermoelectric and has a higher performance than either of its constituent materials. The results may impact not only thermoelectrics research, but also polymer/nanocrystal composites being investigated for photovoltaics, batteries, and hydrogen storage.
