Researchers at the University of Valencia have developed a technique to determine the individual polarities of hundreds of semiconducting nanowires in a single, time-saving process. Led by Ana Cros, director of the University’s Materials Science Institute (ICMUV), the study constitutes a major step forward in both our understanding and application of these structures, since their polarity defines the properties of devices made from them.
Researchers from North Carolina State University have developed a technique for using chains of magnetic nanoparticles to manipulate elastic polymers in three dimensions, which could be used to remotely control new “soft robots.”
Researchers from McMaster University in Hamilton, Ont., have taken atomic-level images of individual nanoparticles during heating that could lead to improved fuel-cell technologies at lower cost, reduce dependence on imported oil and minimize greenhouse gas emissions.
A novel technique that uses optical fibre to track the motion of single, nanoscale viruses has been developed. It is hoped that this technique will allow researchers to understand the mechanisms by which viruses multiply and accumulate.
Using a new procedure researchers at the Technical University of Munich (TUM) and the Ludwig Maximillians University of Munich (LMU) can now produce extremely thin and robust, yet highly porous semiconductor layers. A very promising material – for small, light-weight, flexible solar cells, for example, or electrodes improving the performance of rechargeable batteries.
R&D Magazine recognized UCF and Jayan Thomas, at its annual R&D 100 Awards. Widely known as the “Oscars of Invention,” the prestigious R&D 100 Awards have a 50+ year history of honoring excellence in technology innovations.
A beam of ions has been used to successfully engrave magnetic regions into an alloy with a resolution of 10 atoms. This new method of producing nanoscale magnets could be widely used in the electronics industry.
Ting Xu, a polymer researcher from the Materials Sciences Division of Lawrence Berkeley National Laboratory (Berkeley Lab), has developed a novel set of nanocarriers that are produced from the self-assembly of polymers and amphiphilic peptides. Amphiphiles are a type of chemical compounds that have both lipophilic and hydrophilic characteristics. Micelles are spherical amphiphile aggregates. These nanocarriers have a structure of coiled-coil 3-helix micelles and hence, referred to as 3HM.
New research has shown quantum dots can be used to map neural networks in the brain by allowing neural signals to be visualised in real time. This breakthrough will allow further insight into neural communication in both normal and abnormal brains.
A novel 'flexo-electric' material that generates electricty upon compression has been developed. The material shows significant advantages over piezoelectric materials as it is non-toxic and generates a higher voltage at the nanoscale. It is hoped that the material will be used in self-charging pacemakers and ultra-sensitive sensors.
