Spiders spinning electrically charged nanofibers
A spider commonly found in garden centres in Britain is giving fresh insights into how to spin incredibly long and strong fibres just a few nanometres thick.
Demystifying nanocrystal solar cells
Researchers have developed a comprehensive model to explain how electrons flow inside new types of solar cells made of tiny crystals. The model allows for a better understanding of such cells and may help to increase their efficiency.
Electronic circuits with reconfigurable pathways closer to reality
Multitasking circuits capable of reconfiguring themselves in real time and switching functions as the need arises - this is the promising application stemming from a new discovery.
Joint international research project leads to a breakthrough in terahertz spectroscopy
Although terahertz spectroscopy has great potential, especially for environmental monitoring and security screening applications, it previously could not be used effectively to study nanocrystals or molecules at extremely low concentrations. An international team has found a solution to this problem by increasing the technique's sensitivity using metallic nanostructures.
Nanowire clothing could keep people warm
Scientists have developed a novel nanowire coating for clothes that can both generate heat and trap the heat from our bodies better than regular clothes.
Researchers use sound to slow down, speed up, and block light
Researchers have experimentally demonstrated, for the first time, the phenomenon of Brillouin Scattering Induced Transparency (BSIT), which can be used to slow down, speed up, and block light in an optical waveguide. The BSIT phenomenon permits light to travel in the forward direction while light traveling in the backward direction is strongly absorbed.
Building a graphene-based future for Europe
The European Union is investing heavily in the exploitation of graphene's unique properties through a number of research initiatives such as the SEMANTICS project running at Trinity College Dublin.
Nanoscale mirrored cavities amplify, connect quantum memories
Advance could lead to quantum computing and the secure transfer of information over long-distance fiber optic networks.
Holes in valence bands of nanodiamonds discovered
Researchers hope that their properties might be altered to permit nanodiamonds to be used as catalysts for generating hydrogen from sunlight.
