Scientists are pioneering the use of nanomaterials in compact, sensitive, fast, low-cost terahertz detectors with potential in applications such as biomedical diagnostics, airport security screening and high data-rate wireless communication.
To construct ligand-directed 'active targeting' nanobased delivery systems, aptamer-equipped nanomedicines have been tested for in vitro diagnosis, in vivo imaging, targeted cancer therapy, theranostic approaches, sub-cellular molecule detection, food safety, and environmental monitoring.
Researchers obtain conductivity values for stroncium iridate 250 times higher than in normal conditions, just pressing with nanometric needles. The results where obtained thanks to the use of the atomic force microscope (AFM) showing that the material could become a good candidate for future applications in sensors and electronics.
Researchers have made an advance in manufacturing molybdenum disulfide. By growing flakes of the material around 'seeds' of molybdenum oxide, they have made it easier to control the size, thickness and location of the material.
Molecular beam epitaxy systems enables scientists to control the properties of new crystals with exquisite precision, right down to the atomic level. They can grow nanomaterials with features just a few billionths of a meter across, and even control how many electrons they have inside them.
Researchers manipulated zinc oxide, producing nanowires from this readily available material to create a ultra-violet light detector which is 10,000 times more sensitive to UV light than a traditional zinc oxide detector.
Scientists announced today that they demonstrated interaction between light and sound in a nanoscale area. Their findings elucidate the physics of light-matter coupling at these scales - and pave the way for enhanced signal processing on mass-producible silicon photonic chips.
A research team has identified and synthesized a material that can be used to create efficient plasmonic devices that respond to light in the mid-infrared range. This is the first time anyone has demonstrated a material that performs efficiently in response to this light range, and it has applications in fields ranging from high-speed computers, to solar energy to biomedical devices.
Researchers have demonstrated the autonomous computer-controlled assembly of atoms into perfect nanostructures using a low temperature scanning tunneling microscope. The results show the construction without human intervention of quantum confined two-dimensional nanostructures using single atoms or single molecules on a copper surface.
Scientists have succeeded in the synthesis of new ferroelectric silicates with a tetrahedral coordination. The mechanism for the evolution of ferroelectricity was studied by both experiments and theoretical calculations.
Corannulene is a carbon molecule with a unique shape (similar to the better known fullerene) and promising properties. Scientists carried out computer simulations of the molecule's properties and discovered that it might help overcome the difficulties building molecular circuits.
