| Move over, silicon, there's a new circuit in town Posted: 17 Jun 2014 01:43 PM PDT When it comes to electronics, silicon will now have to share the spotlight. Scientists have now overcome a major issue in carbon nanotube technology by developing a flexible, energy-efficient hybrid circuit combining carbon nanotube thin film transistors with other thin film transistors. This hybrid could take the place of silicon as the traditional transistor material used in electronic chips, since carbon nanotubes are more transparent, flexible, and can be processed at a lower cost.  |
| Sub-wavelength images to be made at radio frequencies Posted: 17 Jun 2014 08:22 AM PDT Imaging and mapping of electric fields at radio frequencies currently requires structures about the same size as the wavelength of the RF fields to be mapped. New theoretical and experimental work suggests an innovative method to overcome this limit. The new technique uses a pair of highly stable lasers and rubidium atoms as tunable resonators to map and potentially image electric fields at resolutions far below their RF wavelengths.  |
| With light echoes, the invisible becomes visible Posted: 17 Jun 2014 06:32 AM PDT Scientists have developed a novel camera system which can see around the corner without using a mirror. Using diffusely reflected light, it reconstructs the shape of objects outside of the field of view. A laser shines on the wall; a camera watches the scene. Nothing more than white ingrain wallpaper with a bright spot of light can be seen through the lens. A computer records these initially unremarkable images and as the data is processed further, little by little, the outlines of an object appear on a screen.  |
| Fuel cells utilized to produce electricity from process industry by-product hydrogen Posted: 17 Jun 2014 06:28 AM PDT Scientists have developed a pilot-scale power plant based on fuel cells that utilizes by-product hydrogen from the process industry. The system produces electricity from hydrogen generated as a by-product of a sodium chlorate process at a high electric efficiency and is the first of its kind in the Nordic Countries.  |
