New research takes energy efficient windows a step further by proposing a new 'smart window' design that would harvest the sun's energy in the winter to warm the house and reflect it in the summer to keep it cool.
At extremely small scales, looks can be deceiving. While at first glance you might see lily pads floating on a tranquil pond, this image is actually a clever adaptation of a snapshot taken on a scanning electron microscope.
Scientists have successfully observed the Auger recombination in CdSe quantum dots occurring at a few picosecond timescales by utilizing transient absorption spectroscopy. The research group demonstrated that the process can be controlled through metamaterial nanostructures for the first time.
3D holograms, previously seen only in science fiction movies, may soon make their way into our daily lives. Until now, 3D holograms based on phase shifting holography method could be captured using a large, specialized camera with a polarizing filter. However, a research group has just developed technology that can acquire holograms on mobile devices, such as smartphones.
