Self-healing Composite Membranes for Fuel Cell Applications

Wang L., Advani S.G., Prasd A.K., University of Delaware, US

Defects in the form of pinholes and cracks can occur in the membrane due to a combination of chemical and mechanical degradation mechanisms during operation of the polymer electrolyte membrane fuel cell. Such defects are [...]

Why Hydrogen?

Blanchet S., Nuvera Fuel Cells, US

Modern civilization has grown reliant on plentiful, cheap and convenient energy from fossil fuels. Now, the reality of climate change has compelled us to reconsider our current ways of producing and using energy. The standardization [...]

Fluorescent post-synthetic modified MOFs for methane sensing

Cárdenas J.C., Castillo L.A., Molano W., Sierra C.A., Reiber A., Universidad de los Andes, CO

Since the last decade, Colombia has been experienced a boom in coal mining due to the large amount of environmental licenses granted by the government. The growth of this activity triggered a concern in finding [...]

Regeneration of used motor oil by supercritical carbon dioxide

Rudyk S., Spirov P., Sultan Qaboos University, OM

Motor oil is used for lubrication in all kinds of cars and engines, which leads to large quantities of used motor oil. 570 million litres of used motor oil are produced every year in the [...]

Rheological Behavior of Novel Switchable Cationic Surfactant in High Salinity Carbonate Reservoirs

Gurusinghe N., Ramadan G., Liebum M., Nguyen Q.P., The University of Texas at Austin, US

The use of viscoelastic (VES) or polymer-like surfactant solutions are important in applications related to enhanced oil recovery and subsurface conformance control. VES resembles polymer where it acts as a mobility control agent to promote [...]

Rheological Characterization of a Novel Viscoelastic Surfactant for Subsurface Applications

Liebum M., Nguyen Q.P., The University of Texas at Austin, US

Viscoelastic solutions (VES) are used in many applications including oil and gas operations regarding reservoir stimulation and enhanced oil recovery to modify rheology properties in the subsurface. In general, the viscoelastic property of the surfactant [...]

A Novel Approach to Reducing Water and Energy Consumption in Oil Production

Pavia M.R., Glori Energy, US

Of all the oil discovered in the world to date, 60-70% remains trapped in the reservoir. Glori Energy has developed a novel oil recovery biotechnology, the AERO (Activated Environment for Recovery of Oil) Technology, which [...]

Asphaltene processing with suspended nanocatalyst. Relevance to in situ upgrading

Isquierdo F., Pereira-Almao P., Scott C.E., University of Calgary, CA

Hot fluid injection is a patented process developed at the University of Calgary by a group of researchers at the Schulich School of Engineering. It focuses on reducing the environmental footprint of heavy oil production [...]

Development and Testing of Thermosensitive Poly(NIPAm-AA)/Nano-SiO2 Composite Blocking Agent for Shale Gas Drilling Operations

Wang W., Qiu Z., Chen G., Zhong H., Huang W., Cao J., China University of Petroleum, CN

Nanotechnology has already contributed significantly to technological advances in energy industry and has the potential to revolutionize the drilling industry. Traditional blocking agents are difficult to form effective mud cake to prevent liquid penetration due [...]

Design of a heat-recirculating combustor for a thermophotovoltaic system

Kim H.K., Kim T.-Y., Kim H.K., Kim T.-Y., Kwon O.C., School of Mechanical Engineering Sungkyunkwan University, KR

Recently, the demand for light, fast-charging and long-lasting portable power sources to replace current lithium-ion batteries has been increased because of development of portable electronic devices such as laptop computers, cellular phones and signal equipments. [...]
