Seeing the fine-scale properties of materials relevant to nanotechnology is a prominent challenge that currently can be met only under ideal conditions. Coherent X-ray imaging promises to greatly expand the range of materials and environments in which these important properties can be observed.
Researchers from Ulsan National Institute of Science and Technology (UNIST) demonstrated high-performance polymer solar cells (PSCs) with power conversion efficiency of 8.92% which is the highest values reported to date for plasmonic PSCs using metal nanoparticles.
Researchers at CRANN, Ireland's leading nanoscience institute, funded by Science Foundation Ireland and based at Trinity College Dublin, have discovered a new concept in sensor-development. The research provides a completely new platform for the development of sensors worldwide and will lead to low-energy, remotely powered sensors that have greater detection capacity than those currently available.
Researchers deformed mirrors in order to disrupt the regular light path in an optical cavity and, surprisingly, the resulting chaotic light paths allowed more light to be stored than with ordered paths.
The new material's artificial 'atoms' are designed to work with a broad range of light frequencies. With adjustments, the researchers believe it could lead to perfect microscope lenses or invisibility cloaks.
Scientists have discovered highly conductive polymer behavior occurring at a polymer/nanocrystal interface. The composite organic/inorganic material is a thermoelectric and has a higher performance than either of its constituent materials. The results may impact not only thermoelectrics research, but also polymer/nanocrystal composites being investigated for photovoltaics, batteries, and hydrogen storage.
A team led by Professor Keon Jae Lee from the Department of Materials Science and Engineering at KAIST has developed in vivo silicon-based flexible large scale integrated circuits (LSI) for bio-medical wireless communication.
A consortium of scientists from across the country has found that breathing ultrafine particles from a large family of materials that increasingly are found in a host of household and commercial products, from sunscreens to the ink in copy machines to super-strong but lightweight sporting equipment, can cause lung inflammation and damage.
RTI is expanding the utility of its Nanomaterial Registry by partnering with research organizations, universities, and industry in the nanomaterial research community to answer important questions on the connections between nanomaterial physical and chemical characteristics and nanomaterial benefits and risks.
Columbia Engineering researchers have developed a technique to isolate a single water molecule inside a buckyball and to drive motion of the so-called 'big' nonpolar ball through the encapsulated 'small' polar H2O molecule, a controlling transport mechanism in a nanochannel under an external electric field. They expect this method will lead to an array of new applications, including effective ways to control drug delivery.
Researchers were able to detect for the first time a major contributing factor to this limitation: trace residues of catalyst material left over from the development process prevent the organic photovoltaics from converting the maximum amount of sunlight to electricity.
