A wrench or a screwdriver of a single size is useful for some jobs, but for a more complicated project, you need a set of tools of different sizes. Following this guiding principle, researchers have engineered a nanoscale fluidic device that functions as a miniature 'multi-tool' for working with nanoparticles.
In a step toward solving a long-standing problem in semiconductor manufacturing, scientists at JILA and collaborators have used their unique version of a 'fine-toothed comb' to detect minute traces of contaminant molecules in the arsine gas used to make a variety of photonics devices.
The roadmap 'The use of nanotechnologies in the manufacturing of Light-emitting diodes' describes the different types of light-emitting devices and compares their possible market future with trends observed currently in the light-emitting diodes (LED) segment.
COST, the European Cooperation in Science and Technology, invites researchers throughout Europe to submit proposals for research networks and use this unique opportunity to exchange knowledge and to embark on new European perspectives.
Not that many companies claim they can turn a kilo of collagen from discarded hoki skins into a fibre that could reach all the way to the Sun. Auckland-based nano-technology start-up company Revolution Fibre does.
The new material, known as Nano Adaptive Hybrid Fabric (NAHF-X), is nicknamed 'fuzzy fiber' for its multiscale capabilities in electrical and thermal conductivity, chemical sensing and energy storage and conversion.
Call it the anti-sunscreen. That's more or less the description of what many solar energy researchers would like to find - light-catching substances that could be added to photovoltaic materials in order to convert more of the sun's energy into carbon-free electricity.
Scientists at the University of Toronto in Canada have shown that inexpensive nickel can work just as well as gold for one of the critical electrical contacts that gather the electrical current produced by their colloidal quantum dot solar cells.
