Thermoelectric properties of molecular nanostructures

Kruchinin S.P., Bogolyubov Institute for Theoretical Physics, UA

We use the concept of resonant tunneling to calculate the thermopower of molecular nanosystems. It turns out that the sign of the thermovoltage under resonant tunneling conditions depends sensitively on the participating molecular orbital, and [...]

Feasibility of Wheel-Based Magnetostrictive Energy Harvester

Park Y.W., Wereley N.M., Park Y.W., Chungnam National University, KR

Manually-pushed carts with rotating wheels are easily seen around us. Also, active RFID has been gaining ground toward commercial usage. Currently possible power supply may be a rechargeable or disposable battery for the reader. The [...]

Ammonia Decomposition on Carbon Supported Cobalt Catalyst

Zhang H., Alhamed Y.A., Petrov L., Kojima Y., King Abdulaziz University, SA

Liquid ammonia has both high energy density and high hydrogen storage capacity which makes it suitable for on-board generation of COx free hydrogen by catalytic ammonia decomposition (AD). Cheap catalysts based on cobalt were considered [...]

Electrical conductivity studies of nanocrystalline Dy3+ doped CaMoO4 synthesized by sol-gel process

Jena P., Nallamuthu N., Venkateswarlu M., Satyanarayana N., Pondicherry University, IN

Oxygen ion conducting solid electrolytes have many device applications such as sensors, solid oxide fuel cells, oxygen pumps, electrochemical reactors and steam electrolysis cells. Among these, solid oxide fuel cells (SOFCs) have attracted great attention [...]

Electrospun Nanofiber Membranes and Electrodes for Fuel Cells

Wycisk R., Ballengee J., Park J.W., Brodt M., Pintauro P.N., Vanderbilt University, US

The focus of our research group has been on the use of electrospinning for the fabrication of nanofiber membranes and electrodes for PEM fuel cells. We have demonstrated dramatic improvement in fuel cell performance and [...]

Renewable Energy Technology Gains by Interfacial Engineering with Carbon Nanomaterials

Vander Wal R.L., The Pennsylvania State University, US

Creating a new paradigm, nanomaterials, when used as interfacial modifiers have the potential to significantly alter the energy landscape, given that these processes occur predominantly at interfaces. The key concept is that the nanomaterials serve [...]

Complex Adaptive Systems – Energy Metrologies for Nanobiomaterials in Artificial Photosynthesis

Greer M., Lockheed Martin, US

Municipal street and public space lighting serve critical safety and security functions but their associated costs can be one of the more significant items in O&M budgets. While the concept of Bio LED trees have [...]

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 [...]
