Comprehensive Microscopy Analysis of Au/Ag Nanoclusters on Silica Nanospheres

Qian H., Shen W., Cui K., Cho J., Fenniri H., National Institute for Nanotechnology, CA

we report a comprehensive structural and morphological analysis of gold (Au) / silver (Ag) nanocluster (shell) on silica (SiO2) nanosphere (core) with transmission electron microscopy (TEM) based techniques, including scanning transmission electron microscopy (STEM) tomography, [...]

In-situ structural characterization of SWCNTs for probing the polymer/nanorod interactions

Liu T., Florida State University, US

Quantitative characterization of the structures of single-walled carbon nanotubes (SWCNTs) in the dispersion is important. It provides critical information for quality assurance of SWCNT dispersions, and more importantly for understanding and optimizing the properties and [...]

Electrospun Carbon nanofibers-Based Supercapacitors

Zhou Z.P., North Dakota State University, US

For efficient use of conductive polymers, such as Polyaniline (PANI) and Polypyrrole (PPy), in pseudocapacitors and other electrochemical applications, the poor conductivity of the conductive polymers is a major problem. To solve the problem, here [...]

Direct nanoscale 3D characterisation of Ge-Sb-Te and Ge-Te phase change films

Grishin I., Kolosov O.V., Lancaster University, UK

DC magnetron sputter-deposited Ge-Sb-Te and Ge-Te based phase change thin films were investigated via a variety of Scanning Probe Microscopy techniques. Micron and sub-micron crystalline and amorphous bit patterns were induced with laser heating and [...]

Nano-contacts and Nano-interconnects

Monty G., Underwriters Laboratories, and IEC TC113, US

This oral paper is the result of nearly 3 years of review and analysis of the state-of-the art of nano-contacts and nano-interconnects. An analysis of over 80 technical articles was performed, including interviews with some [...]

Investigation of Optical Properties of layered MoS2

Shukla S., Saxena S., Mazur E., Indian Institute of Technology - Bombay, IN

The motivation of the research work to be presented is to investigate in details the optical properties of Molybdenum disulphide. Raman spectrum and Photoluminescence spectrum of few layers of Molybdenum disulphide have been analyzed in [...]

Silver Precipitation in Energy-Scavenging Aluminum Nitride Resonators

Alleyne F.S., Ford M., Gronsky R., Yen T.-T., Pisano A.P., University of California-Berkeley, US

Despite more than a decade of experience in manufacturing of nanoelectromechanical systems (NEMS) incorporating piezoelectric elements, modern devices are still plagued by delamination at the electrode/piezoelectric interface. Consequently the electric field essential to generate and [...]

Lipid Nanoparticles as Novel Carrier for Broad-spectrum Sunscreen Formulations

Deng X.Y., Zhou H.J., Chen Y.L., Wang J.M., Xia Q., Southeast University, CN

The most widely used UVA absorber in broad-spectrum sunscreens is 4-tert-butyl-4’-methoxydibenzoylmethane (avobenzone). In the sunlight, however, it will be photolysised rapidly and its photoprotection against UVA will greatly decrease. A photoprotective formulationwas developed with an [...]

Photoacoustic Study of CdS quantum Dots for Photovoltaic Applications

Abdallah S., Al-Hosiny N., Badawi A., Taif University, SA

Recently, CdS quantum dots (QDs) have become one of the promising materials for high efficiency photovoltiac solar cell.. In this work we investigate the optical properties and photovoltaic characterization of CdS QDs -sensitized solar cells [...]

Comparing Nanorulers for Nanoparticles

Bodycomb J., Bath F., Treviranus I., Park K., Hou A., Horiba Scientific, US

Nanoparticle development and manufacturing require particle characterization to determine if design or quality goals are being met. Scattering techniques are the method of choice for analyzing average size and size distribution. There are two light [...]
