Decomposition of Methanol Catalyzed by Cu-ZnO@C

Hong C.-I., Kang H.Y., Chang F-C, Paul Wang H., National Cheng Kung University, TW

Decomposition of methanol (DM) to CO and H2 can be catalyzed by Cu-ZnO@C core-shell nanoreactors. It is found that reactivity of DM catalyzed by the nanoreactors increase with an increase in the fractions of ZnO [...]

Application Magnetite of Nanoparticles (ICNB Preparation) as Magnetically-Resonant Contrasting Means During Visualization of Tumours

Belousov A.N., Laboratory of Applied Nanotechnology Belousova A.N., UA

In investigation on animals (Vistar rats) was proof that magnetite of nanoparticles (ICNB) are contrast means for malignant tumour visualization. Was been shown that magnetite of nanoparticles have contrast effect when performing magnetic resonance imaging [...]

Separation of Nanoparticles from Nanoparticle Enhanced Phase Change Material

Haroon Sheikh M., Sharif M.A.R., Rupar P.A., University of Alabama, US

The phase change materials(PCM) have been used to store energy as a latent heat of fusion. Paraffin oils are proved to be the best suitable material as a PCM, however its heat capacity is lower [...]

Three-dimensional Core@Shell Nano-Array Electrodes for Integrated Lithium-Ion Microbatteries

Mao Y., Sun X., Li Q., Lv Y., University of Texas-Pan American, US

In micro/nanoelectromechanical systems (MEMS/NEMS) and biomedical devices, the desired on-board power storage and delivery occur in exceptionally small geometric scales, where amount of energy stored on given footprint (J/mm2) precedes that in either unit weight [...]

Large Scale Energy Storage with Thermal Matrix Energy Storage

Sutherland S., Lynch G., Pietsch T., Kelvin Storage Technologies, Inc, US

The presentation reviews the design and technical innovations for storing energy as heat in a graphite core at temperatures far above the melting point of steel. The high temperatures reached, over 4000F, enable storing vast [...]

Rechargeable Nanofluid Electrodes for High Energy Density Flow Battery

Timofeeva E.V., Katsoudas J.P., Segre C.U., Singh D., Argonne National Laboratory, US

Nanomaterial suspensions in liquids (nanofluids) are the new expanding area in nanotechnology, with applications as wide as biomedical, lubrication, thermal management, energy generation, energy conversion, and energy storage. Variety and unique characteristics of nanomaterials allow [...]

Novel Electrolytes for Supercapacitors

Stiemke F., Blumenröder B., Schubert T.J.S., IOLITEC Ionic Liquids Technologies Inc., US

Supercaps using ionic liquids (ILs) as novel electrolytes have gained much attention because of their interesting profiles of physical and chemical properties , such as tunable viscosities and conductivities, chemical and thermal stability as well [...]

Flexible and Turnable Biomimetic Pyruvate Dehydrogenase Complex (PDC) Supercapacitors

Thornton J., Christelle C., Chen E.T., Advanced Biomimetic Sensors, Inc., US

Flexible supercapacitors are challenged by low energy density and short discharge time. We report a new type of biomimetic pyruvate dehydrogenase complex (BIMPDC) supercapacitors having the self-assembling membrane (SAM) offer orders of magnitude higher in [...]

Pseudocapacitive random and aligned nano-porous electrode materials for supercapacitors

Saruhan B., Gönüllü Y., Arndt B., German Aerospace Center, DE

Commercial electric double layer capacitors store energy in an electric field. This is caused by charged particles arranged on two electrodes consisting mostly of carbon, in the form of a double layer. Such double layer [...]

High Performance Supercapacitors Based on Thermal Reduced Graphene Oxide

Perego D., Franz S., Bestetti M., Borioli C., Politecnico di Milano, IT

THERMALLY REDUCED GRAPHENE OXIDE BASED SUPERCAPACITORS HAVE BEEN FABRICATED AND TESTED. ELECTRODES BASED ON METAL SUBSTRATE (TI, AISI304, NI, AL) WERE FABRICATED BY EITHER BY ELECTROPHORESIS AND SPRAY COATING OF GRAPHENE OXIDE SOLUTIONS. ELECTROCHEMICAL TEST [...]
