Ultra Low Cost Nano Porous Membrance For Fuel Cell Applications.
Dr.Arnon Blum, Hanan Terkel, Emanuel Peled
GFC
***********************
GreenFuelCells (GFC) is a Tel AViv University project, formed to develop advanced fuel cells (FC) for a variety of application. Our technology solved many of the fundamental problems delaying the commercialization of FC's. For the mobile electronics market GFC will provide a FC based power source that will be equivalent in price to Li-Ion batteries while delivering more than twice the energy levels.
A notebook PC will operate for more than 10 hrs under normal operating conditions when powerred by a GFC power source. Furthermore this power source will be fueled by a proprietary non hazrdous fuel, another unique feature of our technology. For light transportation vehicles such as scooters, GFC can provide the advantages of an electric vehicle with refueling capabilities. Scooters based on GFC's fuel cells system, will be lighter, environmentally cleaner, have higher driving range, better mileage and use cheaper fuel compared to gas based scooters.
GFC's patentedtechnologies enable the creation of the best and safest products in the market characterized by: Smaller systems (due to industry's highest power density), Long Running times High fuel utilization, Affordable product costs. Our main technological strengths are: A breakthrough patented Nano-Porous Membrane (based on nano materials) with highest power density and highest fuel utilization ever published. Ultra low cost membrane (down to 4$/m2 compared to over 700$/m2 of competitive membranes).
Our patented fuel does not require FAA certification thus allowing safe utilization and ransportation of fuel cell power sources on airplanes. The end product is smaller, simpler and lower in cost compared to similar systems based on competing technologies.

A new Method For Coating Of Magnetic Metal Shaped Nanoparticles On Fibrous Supports
Dr. Uri Meytal
Technion
***********************
A new method for coating of fibrous supports with shaped magnetic metal nanoparticles Uri Meytal Department of Chemical Engineering, Technion, Israel Institute of Technology Abstract Carbon-coated magnetic-metal nanoparticles are of great interest in potential applications to magnetic recording media, magnetic toner and so on. The carbon coating protects magnetic-metal particles against environmental degradation. The coating efficiently serves the role of reducing the magnetic coupling between individual particles, when applied to the recording media.
In order to realize ultra-high-density magnetic recording media of the next generation, size-controlled magnetic nanoparticles isolated by thickness-controlled non-magnetic phases are indispensable. So far, metal nanoparticles coated with graphitic layers, called carbon nanocapsules', have been produced by conventional arc-discharge, modified arc-discharge and ion-beam sputtering methods. Here, a new wet chemical deposition (WCD) method for synthesizing of shaped magnetic metal (Fe, Cu, Pd) nanoparticles on fibrous supports, like activated carbon cloth (ACC) has been presented. We will discuss the coating mechanism and advantages in our method.
