High Energy Density Supercapacitor Based on a Hybrid Carbon Nanotube – Reduced Graphite Oxide Architecture

Bekyarova E., Ramesh P., Jha N., Itkis M.E., Haddon R.C., Carbon Solutions Inc, US

We report a high energy supercapacitor device that utilizes hybrid carbon electrodes and the ionic liquid, 1-butyl-3-methylimidazolium tetrafluoroborate (BMIMBF¬4) as an electrolyte. The hybrid electrodes were prepared from reduced graphite oxide (rGO) and purified single [...]

Save Hawai‘i…Save the Planet

Barlow J., Power Alternative, US

Petrochemicals are quintessential ingredient in most all products, technologies, and conveniences of modern lifestyle, so it is imperative that we eliminate abusing it to fuel modes of progress, and transports. Power Alternative is scientific R&D [...]

Challenges in Thermal Energy Storage for Solar Power Plants

Wibbenmeyer L., Smith T., Craig J., Abener / Abengoa, US

The need for renewable and sustainable energy is clear. Concentrated Solar Power (CSP) is one means of power generation that is becoming economically viable to meet those needs. CSP however, does have limitations due to [...]

BioGenerator – a Novel Bio-Technology for the Conversion of Hydrogen to Electricity

Karamanev D., University of Western Ontario, CA

One of the promising applications of the H2-to-electricity converters is in the field of power smoothing and storage. The technologies currently considered for smoothing and storage have certain problems. The use of hydrogen as a [...]

Tailoring Pt-Alloy Cluster Nanoparticles for Enhanced Electrocatalytic Activity

Balu R., Roy Choudhury N.K. Dutta N., Elvin C.M., Hill A.J., University of South Australia, AU

Polymer electrolyte membrane fuel cell, PEMFC is an electrochemical energy conversion device that has the potential to be an alternative to internal combustion engines. However, the complexity and slow oxygen reduction reaction (ORR) kinetics on [...]

An Electron-Relay Prototype Supercapacitor Mimics Electrophorus Electricus’s Reversible Membrane Potential for Multiple-organ Discharge

Chen E.T., Ngatchou C., Advanced Biomimetic Sensors, Inc., US

Electrophorus Electricus (EE) is known to discharge electric voltage through multiple organs based on Reversible Membrane Potential (RMP). We report a new type of supercapacitor for mimicking the EE’s RMP based on an electron-relay nano-biomimetic [...]

Fiber Optic Based Evanescent Wave Sensor for the Detection of Elemental Mercury Utilizing Gold Nanorods

Crosby J.S., Lucas D., Koshland C.P., University of California-Berkeley, US

We have developed a fiber optic based sensor for the detection of atmospheric elemental mercury that uses gold nanoparticles as the sensing medium. Previous work has established that the Localized Surface Plasmon Resonance Peak blue-shifts [...]

The identification of PM parameters in compression ignition engines

Pielecha J., Poznan University of Technology, PL

The paper discusses the possibility of a synthetic approach to the parameters of PM generated by Diesel engines. The authors felt compelled to realize the task following the obtainment of positive results of the PM [...]

Simultaneous Desulfurization and Particulate Removal with ZnO Dispersed Ceramic Filters at High Temperatures

Wang H.P., National Cheng Kung University, TW

Flue gas cleaning at high temperatures can increase thermal efficiency with more importantly to simplify processes and lower cost. The main objective of this work was to investigate the feasibility of simultaneous desulfurization and particulate [...]

TiO2-based photocatalytic and antimicrobial coatings: comparison between sol-gel and electrodeposited silver/TiO2 nano-composites

Diamanti M.V., Magagnin L., Del Curto B., Candiani G., Pedeferri MP., Politecnico di Milano, IT

Among possible ways to improve air quality in urban atmospheres, the use of nanostructured TiO2 films as photocatalysts is an excellent way to mitigate the problem, although it cannot offer a complete solution. TiO2 also [...]
