ROS Evaluation for Series of CNTs Using the ESR Method and the Effects of CNT Mophology

Tsuruoka S., Takeuchi K., Koyama K., Endo M., Fujisawa K., Matsumoto H., Saito N., Usui Y., Porter D.W., Castranova V., Shinshu University, JP

Carbon nanotubes (CNTs) are becoming important materials in industry. It is a concern that CNTs may induce carcinogenic responses through pulmonary exposure. It has been recently reported1-6 that CNTs scavenge ROS depending on their morphology. [...]

Optimization study of Supercapacitor electrode material composition and thickness for enhanced performance of the Supercapacitor

Ranade A.P., Jung D.Y., Sammakia B.G., Eilertsen T., Davis T., Binghamton University, US

A prototype electrode was constructed to verify the optimization of composition of materials for the supercapacitors. Surface area analysis and SEM images were used initially to select the most appropriate active carbon from a group [...]

Water Soluble Carotenoid Conjugates with Oligo- and Polysaccharides. Synergy of Drug Transport and Efficacy

Polyakov N.E., Leshina T.V., Meteleva E.S., Dushkin A.V., Konovalova T.A., Kispert L.D., University of Alabama, US

We present first example of water soluble conjugates of carotenoids with a triterpene glycoside, glycyrrhizic acid (GA), and natural polysaccharide arabinogalactan (AG), studied by various physicochemical techniques. Carotenoids are well known as a class of [...]

Novel Function of the Boron Icosahedron; a New Mediator of Magnetic Interaction

Mori T., National Institute for Materials Science, JP

Rare earth borides containing the B12 icosahedron display surprisingly strong magnetic interactions although they are magnetically dilute insulating materials with localized f-electrons. A microscopic local probe, ESR, was utilized to investigate the mechanism of the [...]

A Scheme for Electrical Detection of Single Electron Spin Resonance

Martin I., Mozyrsky D., Jiang H.W., Los Alamos National Laboratory, US

We study a scheme for electrical detection of the spin resonance (ESR) of a single electron trapped near a Field Effect Transistor (FET) conduction channel. In this scheme, the resonant Rabi oscillations of the trapped [...]
