One of the issues in using carbon nanotubes for applications is the challenge of separating metallic from semiconducting single-walled carbon nanotubes (SWCNT) after production. Developing a rapid and parallel technique for the electronic characterization of high-density arrays of SWCNT devices is essential for future large-scale production processes of nanoelectronics components. Currently used methods for electronic characterization of SWCNT devices and arrays are time consuming to set up, slow to execute, and not suitable for large-scale deployment. These methods include direct electron transport measurements and scanning probe microscopy,... nanotechnology article
The emerging field of transparent and flexible electronics not only holds the promise of a new class of device components that would be more environmentally benign than current electronics; being able to print transparent circuits on low-cost and flexible plastic substrates also opens up the possibility of a wide range of new applications, ranging from windshield displays and flexible solar cells to clear toys and artificial skins and even sensor implants. Three broad application areas for this technology are taking shape: transparent displays; flexible displays; and transparent/flexible electronics. Traditional materials used for transparent... nanotechnology article
The flurry of recent announcements regarding reports, international cooperations, and new research activities that deal with the potential risks of manufactured nanomaterials is a clear indication that the field of nanotoxicology is gaining momentum - and not too soon. While there still is no coherent international approach to determining if and what risks are posed by what kind of nanotechnology materials, individual research groups are picking certain areas of concern and forge ahead with - often highly specific - toxicology studies. A lack of standards and definitions makes these early investigations hard to compare and sometimes they even... nanotechnology article
Graphene is a recently discovered allotrope of carbon, which consists of a planar single sheet of carbon atoms arranged in honeycomb lattice. It has attracted tremendous attention of the nanotechnology research community owing to a number of unique physical properties. From a practical point of view, some of the most interesting characteristics of graphene are its extraordinarily high room temperature carrier mobility and recently measured extremely high thermal conductivity. The outstanding current and heat conduction properties of graphene are beneficial for the proposed electronic, interconnect, and thermal management applications. There is... nanotechnology article
Neural engineering is an emerging discipline that uses engineering techniques to investigate the function and manipulate the behavior of the central or peripheral nervous systems. Neural engineering is highly interdisciplinary and relies on expertise from computational neuroscience, experimental neuroscience, clinical neurology, electrical engineering and signal processing of living neural tissue, and encompasses elements from robotics, computer engineering, neural tissue engineering, materials science, and nanotechnology. In order for neural prostheses to augment or restore damaged or lost functions of the nervous system they need to be able... nanotechnology article
