Nickel oxide hollow nano-fiber electrodes for electrochemical capacitors

Machida S., Tsutsumi H., Yamaguchi University, JP

Morphology of electroactive materials in electrodes affects their electrochemical performance and capacity of energy storage devices. New architectures (3D) for electrodes and cells will overcome the traditional electrodes’ problems. However, preparation of 3D electrodes needs [...]

Characterization of poly(vinyl alcohol)-based composites prepared by electrospinning technique with in situ coffining process

Hara C., Tsutsumi H., Yamaguchi University, JP

A number of methods are available for preparing a fiber reinforced polymer composite from two or more polymer matrixes and fibers. We propose new type reinforced polymer composites by electrospinning technique with in situ coffining [...]

CdSe nano-particles coated with thiol-terminated oligo(ethylene oxide)for protein targeting reagent

Ito Y., Tsutsumi H., Yamaguchi University, JP

Fluorescent labeling reagents are used as medical and biochemical research reagents that label specific protein, antigen, antibody, and DNA. However, the chromophoric groups (organic compounds) usually are not stable under long-time ultra violet (UV) excitation. [...]

Preparation and characterization of electrospun nickel oxide/polymer fibrous electrodes for electrochemical capacitor

Tsutsumi H., Hosogai S., Yamaguchi University, JP

Electrospinning provides a simple and unique technique for preparation of fibers with the diameters ranging from the nano- to microscale. We prepared the electrospun fiber which contains nickel oxide (NiO) as the electrochemical active material [...]

Characterization of new type polymer composites prepared by in situ coffining electrospun fibers into polymer matrixes

Tsutsumi H., Hara C., Yamaguchi University, JP

A number of methods are available for preparing a fiber reinforced polymer composite from two or more polymer matrixes and fibers. Many difficulties (for example, increasing viscosity of processing fluid, homogeneity of fibers in the [...]

Hydroxyapatite-imidazole-polymer composite films as a proton conductor under no humidified condition

Tsutsumi H., Hisha Y., Yamaguchi University, JP

We prepared the proton conduction system, hydroxyapatite (HAp)-imidazole (Im)-polymer composite films and investigated their structure, conduction behavior and mechanical properties. HAp particles used in our investigation were prepared with two different ways, a-HAp and n-HAp. [...]

CdSe Nanoparticles Modified with Water-soluble Terpolymers and their Application to Biomarkers

Tsutsumi H., Yamada M., Yasui M., Yamaguchi University, JP

Fluorescent labeling reagents are used as diagnosis and research reagents that label specific protein, antigen, antibody, and DNA. However, the chromophoric groups are not stable under long-time Ultra Violet (UV) excitation measurement condition. Nanometer-sized semiconductor [...]
